Thank you, Erica. Good afternoon and thank you all for joining us on our conference call. Starting with highlights of our first quarter results, we concluded the quarter with revenues of approximately $405 million, just above the top end of our guidance. Revenues from our Solar business were $376 million, while revenue from our non-Solar business was $29 million. This quarter, we shipped 3.7 million power optimizers and 182,000 inverters. Our Solar business grew this quarter across all segments and geographies, including record quarterly revenues in Australia, Italy, and France. In North America, we saw a 23% growth in revenues from Q4 to Q1, representing increased demand for both residential and commercial products. Business in Europe is continuing to grow, led by sales in the Netherlands, where we had a record quarter of residential revenues, as well as revenues from Germany, Italy, and Poland. Also noteworthy is our continued growth in France, where we had a record quarter both in residential and commercial sales. In the region outside Europe and the U.S., which includes Australia, Asia-Pacific, Japan, Brazil, Israel, and several other countries, we had our third consecutive quarter of growth and record shipments. Noteworthy among these countries is Australia, where we delivered close to 100 megawatts of products, representing more than 50% of quarter-over-quarter growth. A big part of this momentum was due to the volume shipments of our new three-phase residential inverter optimized for the Australian market. When it comes to new market opportunities, we see Korea as a particularly interesting one. We recently completed certification of our three-phase commercial inverter for installation on commercial rooftops in Korea. As the C&I market in Korea is more than 2 gigawatts in size and considering our strong local presence, we are optimistic about the growth potential there. And indeed, we had already installed more than 10 megawatts of rooftops in a conditional certification setup in the first quarter. As we projected in recent calls, this quarter we began to see meaningful signs of recovery in our commercial business across all regions. Our megawatt shipments of commercial products grew by 35% from last quarter. As we had anticipated and discussed in our last earnings calls, the commercial sector has been slower to recover from the economic downturn during the pandemic, but inventory in our distribution channel is now back to healthier levels. We are seeing a pickup in commercial installations and opportunity pipeline. We expect revenues from the commercial segments to continue and grow back to pre-pandemic levels in the second and third quarter of 2021. On the product side, demand for our battery-ready Energy Hub inverter continues to grow and it is now more than 20% of our residential shipments to the U.S. At the same time, we see growing interest in our self-consumption devices such as our EV charger and water heating product. Our plan to launch our residential battery remains on track. We have active test sites already in the U.S. and will begin initial shipments this quarter. These batteries will be shipped to the U.S., Europe, and later to Australia. The test period is aimed to validate battery performance in the field and sharpen installation practices with the help of some of our select installers. Additionally, the goal is to confirm the system-level battery plus Energy Hub inverter self-consumption and backup scenarios. In a recent study of our global installed base of more than 30,000 systems of SolarEdge backup inverters installed with third-party inverters, we analyzed consumer behavior patterns and system performance through more than 75,000 blackout events lasting more than 5 minutes. We characterized in detail typical blackout frequencies, duration, the power and energy capacity needs, as well as practices to prevent depletion of batteries during extended blackout events. We will be incorporating these learnings into our system in conjunction with maximizing self-consumption and financial decision-making algorithms to enable smart automated system decisions and provide a flexible, easy-to-manage system for the consumer. As we have said in the past, we don't plan for meaningful battery revenues until Q3 of this year. Given the growing demand for energy consumption and storage, which I referred to earlier, we are confident that our storage-ready inverters fitted with our DC coupled battery represent a significant milestone in progressing our vision of a home system that provides both maximization of self-consumption and economic value where relevant, as well as backup capability where and when needed. In the Commercial segment, we see good adoption of our 120-kilowatt Synergy inverter, including a dedicated version for ground mount installations in the U.S. This new high-power inverter is designed to support larger commercial fields and improved economics, as well as simplify installation and commissioning. Our customers can now set up and test the entire installation before even connecting to the AC grid. As the C&I market continues to improve, our new high-power inverter, combined with our recently released 1,100-watt optimizer, offers a means to reduce the cost per watt for installers and increase the adoption of our solution in larger ground mount and rooftop installations. I would like now to elaborate on our operational status. Cycles of component shortages are common in our industry, and we have experienced such cycles before. Based on our past experience, we have adopted a methodology to closely monitor the procurement of components by our contract manufacturers and, at times, manage the supply and demand of components directly from their suppliers. This allows us to identify relatively early cycles of shortages. We typically hold high levels of safety stock and finished goods inventory that allow us to overcome temporary fluctuations in component availability. Additionally, we have developed alternate sources for critical components. As a result, currently, based on the current alignment and delivery schedules with our contract manufacturers and suppliers, we are comfortable in our ability to support the increased demand we are seeing and our projections for further demand increases later in the year. Though at times, this may come at a higher cost due to expedited shipments and cost increases, as is reflected in our gross margin guidance for the forthcoming quarter. On a related note, our Sella 1 factory in Israel is continuing to ramp. We are now employing over 480 workers and manufacturing inverters and optimizers from our own facility, which is on track to reach full capacity by the end of this quarter. The fruits of this investment are already being borne as, thanks to a joint project of our R&D and operational teams in Israel, we have been able to increase the output of our power optimizer automated assembly lines and copied this improved process to our contract manufacturers in other locations. In our non-Solar business, our e-Mobility Division began delivering full powertrain units and batteries for the Fiat E-Ducato in Europe. The ramp of the production line will be gradual and several months will pass until we reach full capacity. In our Energy Storage division, the Sella 2 factory for lithium-ion cells and batteries in Korea is now well underway, with the groundbreaking work behind us and building establishment in process. The factory is expected to start pilot production in the first half of 2022, enabling us to supply our own cells and reduce our dependency on third-party manufacturers. In summary, we are happy with the results of the first quarter and the progress our teams are making across our regions and business units. With this, I hand it over to Ronen, who will review our financial results.

Thank you, Zvi, and good afternoon everyone. This financial review includes a GAAP and non-GAAP discussion. Full reconciliation of the pro forma to GAAP results discussed on this call is available on our website and in the press release issued today. Total revenues for the first quarter were $405.5 million, a 13% increase compared to $358.1 million last quarter and a 6% decrease compared to $431.2 million for the same quarter last year. Revenues from the sale of solar products were $376.4 million, a 15% increase compared to $327.1 million last quarter. U.S. solar revenues this quarter were $162.5 million and represented 43.2% of our solar revenues. Solar revenues from Europe were $158.4 million, or 42.1% of our revenue, and the rest of the world solar revenues were $55.5 million, or 14.7% of our total revenues, driven mostly by record revenues in Australia. Revenue this quarter represented strong demand for our products in both residential and commercial segments in Europe and the rest of the world, with revenues in the United States continuing to be driven by sales of residential products. On a megawatt basis, we shipped to the United States 573 megawatts, to Europe 721 megawatts, and to the rest of the world 397 megawatts. 45% of the total amount were commercial products, and the remaining 55% were residential. Channel inventory remains healthy in all regions in anticipation for Q2 and Q3, which are typically characterized as stronger quarters for the solar industry in general. Point-of-sale data received from our distributors demonstrates strength in all regions. In the United States, where commercial sales were weaker over the last quarter, we see, as anticipated, strong point-of-sale data, which lowers the inventory days within the channels and new project discussions with our customers are expected to yield an increase in our U.S. commercial sales in Q2 and the following quarters. This quarter, our top 10 solar customers represented 62.2% of our solar revenues. One U.S. distributor accounted for more than 10% of the solar revenues. Pricing levels remained stable this quarter across all regions. Blended ASP per watt for our solar products decreased by approximately 8% compared to the last quarter, driven by customer and product mix. This quarter, revenues from our non-solar products were $29.1 million, led by sales of lithium-ion batteries to non-solar customers by Kokam and increased sales from our e-Mobility business that delivered the first full powertrain kits to Stellantis. GAAP gross margins for the quarter were 34.5% compared to 30.8% in the prior quarter and 32.5% in the same quarter last year. Non-GAAP gross margin this quarter was 36.5% compared to 32.5% in the prior quarter and 33.6% in the same quarter last year. Non-GAAP gross margin for the Solar business was a record 39.7%, compared to 36.2% in the last quarter and above our long-term solar gross margin target of 36% plus-minus 1%. This increase in the non-GAAP solar margin is a result of several factors; primarily, we saw a higher portion of residential products, which are characterized by higher gross margins out of the total product mix, improved exchange rate on sales in Europe and Australia, a reduction in the portion of Chinese-made products shipped to the United States and that are subject to U.S. custom tariffs, as well as lower warranty charges as a percentage of revenues associated with the support of our product and economies of scale. 86% of the products shipped to the United States this quarter were not subject to the tariffs, as they were manufactured outside of China. As you can see from our Q2 gross margin guidance, we expect margins to be slightly lower in the coming quarter. Over the last quarter, we experienced a substantial increase in ocean freight prices as a result of the effects of COVID-19 on trade and supply chains. Ocean freight prices have increased by more than 100% over the last month and our pre-negotiated prices have gradually expired and exposed us to higher freight costs worldwide. Another element that affects our margin is increased cost of certain components and freight costs related to the expedited shipments of such components. As Zvi mentioned, we are managing these component shortages in a way that currently allows us to meet the annual operating plan, but such management requires us from time to time to pay higher prices for a component or airship them to our contract manufacturer's facility as supply time also fluctuates. Lastly, the seasonal growth in revenues in Europe and increased sales of commercial products in the United States are both characterized by lower gross margin products in our overall mix. Despite all these factors, our gross margin target and our expectation to meet it remain unchanged at the range of 36% plus-minus 1%. Non-GAAP gross margin for our non-solar activities was -4.7% compared to -6.4% in the previous quarter. The improvement is mainly a result of the growing volumes of powertrain kits supplied this quarter, although volumes are not yet stabilized at the anticipated level that will get us to the low-single-digit target gross margin on this project. On a non-GAAP basis, operating expenses for the first quarter were $76.2 million, or 18.8% of revenues, compared to $72.9 million, or 20.4% of revenues in the prior quarter and $66.3 million, or 15.4% of revenues for the same quarter last year. This increase is a result of our recommenced investment in talent acquisition in our research and development department, as well as the expansion of sales infrastructure in all businesses. Our non-GAAP solar operating expenses as a percentage of solar revenues were 17%, compared to 18.9% last quarter. Non-GAAP operating income for the quarter was $71.9 million, compared to $43.5 million in the previous quarter and $78.6 million for the same period last year. This quarter, non-GAAP solar activities resulted in an operating profit of $85.5 million, compared to an operating profit of $56.5 million last quarter. This number represents 22.7% of our solar revenues and is at the higher end of our 20% to 23% long-term operating profit model. The non-solar activities resulted in a non-GAAP operating loss of $13.6 million, relatively flat to an operating loss of $13 million in the previous quarter. Non-GAAP financial expense for the quarter was $6.3 million, compared to a non-GAAP financial income of $16.9 million in the previous quarter. This expense is mostly a result of unrealized foreign currency fluctuations related to intercompany loans between the group companies. Our non-GAAP tax expense was $10.1 million, compared to $4.6 million in the previous quarter and $12.5 million for the same period last year. GAAP net income for the first quarter was $30.1 million, compared to a GAAP net income of $17.7 million in the previous quarter and $42.2 million in the same quarter last year. Our non-GAAP net income was $55.5 million, compared to a non-GAAP net income of $55.7 million in the previous quarter. However, this net income this quarter is a result of a substantially higher operating profit. GAAP net diluted earnings per share was $0.55 for the first quarter, compared to $0.33 in the previous quarter and $0.81 for the same quarter last year. Non-GAAP net diluted EPS was $0.98, the same as in the previous quarter and a slight increase compared to $0.95 in the same quarter last year. Turning now to the balance sheet, as of March 31, 2021, cash, cash equivalents, bank deposits, restricted cash deposits, and investments were $1.2 billion. Net of debt cash, cash equivalents, bank deposits, restricted bank deposits, and investments were $515.2 million. During the first quarter of 2021, we generated $24.1 million in cash from operations. Accounts receivable net increased nominally this quarter to $271.7 million, compared to $218.7 million last quarter. Days sales outstanding this quarter in the Solar business was 73 days, a decrease from 75 days last quarter. As of March 31, our inventory level, net of reserves, was at $340 million compared to $331.7 million in the prior quarter. This amount reflects slightly lower finished good inventories and higher raw material inventory in both our Solar and non-Solar businesses as we are working through the component shortages and ramping up our e-Mobility powertrain production line. Moving now to the guidance for the second quarter of 2021, we expect revenues for the second quarter to be within the range of $445 million to $465 million. Revenues from the sale of solar products are expected to be within the range of $405 million to $420 million. We expect the non-GAAP gross margin to be within the range of 32% to 34%. Non-GAAP gross margin for the sale of solar products is expected to be within the range of 36% to 38%. I will now turn the call over to the operator to open it up for questions.

Thank you. We'll take our first question from Stephen Byrd of Morgan Stanley.

Hey, thanks so much for taking my questions. Maybe just first talking about the gross margin guidance, you described the cost impact of, for example, shipment costs, etc. And I was just curious for the second quarter, are the sort of costs for those sorts of, I think, it was inventory-related costs, is that fully reflected in 2Q? Or could you see further margin impacts in subsequent quarters that could be a bit larger than what you're seeing in 2Q guidance?

So generally, first of all, the margin is relatively, I would say, a mix of various items other than, of course, the logistic cost, which are also related to mix of products and mix of geographies and currencies. Therefore, spotting one specific element is always a little bit more complicated, and one of them may move and actually overcast the others, such as the exchange rate, for example. But from a perspective related to the logistic costs, basically, our prices are usually pre-negotiated in advance, and we try to close them as much as possible to hedge prices against changes that are happening. We were able, actually, to do it pretty well in the last few quarters. It's simply that over time, the cost went up and our prices elapsed, and therefore we had to pay the higher prices. So right now, I think that we have a pretty clear visibility for the ocean freight prices at least for the quarter where we guided. We do not see a lot of changes happening there. I think that for the quarters to come, we do not have yet numbers to see. We believe that the trend is going to be slightly downward. But of course, as long as the traffic of both in and out from the United States into China and the other areas is somehow disturbed because of COVID and changes in trade patterns, this may change. We do not expect major changes more than we saw this quarter, however, in the next few quarters.

That's really helpful. And then maybe just one follow-up. It's great to see the progress on your energy storage business and you talked about the residential battery being on track for deliveries in the second quarter. Just in general, how are you feeling about the growth potential for that business? I mean, it strikes us that there should be tremendous demand for that product. But just curious compared to your original expectations, how has that sort of process of development and how would you expect rollout? In other words, are you feeling more bullish because demand is very high? Are there logistical issues that would go on the other side of the equation? How are you generally feeling about the growth of the storage business?

I think you hit the nail on the head. Demand is probably not the issue. So the demand is very strong. It's coming from multiple geographies all over the world in general for storage and in particular for an integrated system as we provide. We will be ramping our production line. We'll make the introduction gradual because it is a new product and you want to be a bit cautious in how you roll it out to the field, how you train installers, how you get it installed, and logistics are a challenge, but they're not much more of a challenge than they are in other areas. So the outlook is very positive in this area, but it's not going to be a very sharp hockey stick of tremendous growth from one quarter to another, but we're very encouraged by the demand and by the way the product is shaping out and we're excited to bring it out to the market in the next couple of quarters.

Very good. Thank you very much.

Thank you. And we will take our next question from Philip Shen of ROTH Capital Partners.

Hi, everyone, thanks for taking my questions. Just as a follow-up on the storage question. I was wondering if you could talk about what you think meaningful demand could be in Q3. I think you mentioned that that would be the first quarter. And then perhaps put in context, for us, what kind of growth Kokam, the core business could see in 2021 versus 2020? And if you can talk about pricing for the battery system, that would be fantastic as well? Thanks.

So I'll try to take them one by one, Phil. So, again, demand is very strong in terms of how much we will ship in Q3. We're not yet giving specific guidance as we iron out the plan. And as we said multiple times, we believe it will be already meaningful quantities and revenue. But the exact numbers, we'll guide next quarter. In terms of the pricing, we began to communicate the pricing to select customers in the market and we are obviously aiming it to be competitive and reflect the value of the product. So we won't be on any major edge in terms of significantly higher or lower than market prices for batteries today. And the last question, Phil, I don't recall about the…

So what kind of growth could we see with the Kokam business year-over-year?

So I think that here, Phil, the question is mostly related to the capacity they have. Today, the capacity they have in the older factory in Nonsan is pretty much taken. Therefore, we do expect to see a small growth year-over-year simply due to the fact that they are able to make improvements. But it's not going to be something that will move the needle in the overall SolarEdge numbers for this year. The biggest growth will come starting next year because once Sella 2 will start producing cells, this will be the first simple cells in the first quarter and go into full production within the year. Then our expectation was around $300 million, as we communicated in the past. However, we do see that this assumption that was based on relatively large ASP erosion in the cell industry is not really materializing, and therefore the effect could be higher. But at least for us, the way that we're planning is about $300 million of incremental revenues in 2022.

Great. Thank you both. As my follow-up question here, as it relates to litigation, I was wondering if you guys could provide an update on any of the risks and opportunities as it relates to what's going on, the lawsuits in China or in Germany? What is the risk that you guys may be prevented from manufacturing in China? And if so, do you have any contingency plans around that?

So we discussed several times over the years that the litigation has been going on. These are typically very long processes and usually don't end in a dramatic fashion in one way or another, so all of this is still ongoing, as you mentioned both in Europe and in China. Nonetheless, we obviously have set in motion contingency plans based on scenarios that might evolve. But so far also, as we indicated in our guidance for the quarter and our message for the subsequent quarter, we are comfortable with our ability to deliver on the increased demand that we're seeing.

And we will take our next question from Colin of Oppenheimer.

Could you talk a little bit about what's going on with seasonality in Europe and sell-through in Europe both in the commercial and the residential market? And a comment on diversification of the geographic footprint where you guys are selling through.

Yes. So Europe had an interesting winter in the fact that the first couple of months were pretty tough winter and installation rates were kind of slow. Sometime from mid-February and on, things opened up, and the installation rate is gone up, sell-through is on the rise, and most of our dialogues with our distributors across Europe, both for residential and commercial are about pull-ins and expedite these days as the market woke up very aggressively and inventory levels are relatively low compared to the full capability from the installers. In terms of the general breakdown, if that's what you're referring to, we are stabilizing more on a 40% U.S., 40% roughly Europe, and 15% rest of the world. The rest of the world is growing quite quickly, and that pattern might shift later on. We are investing a lot into places like Korea that I mentioned. Taiwan is a good growing market. Thailand is a good growing and interesting market as well. The growth rate in these regions of the market is higher than that in the U.S. and Europe, and we are making the investments in order to capitalize on it. Still, nonetheless, for the foreseeable future, that mix of roughly or fluctuating between 40% to 50% each between Europe and the U.S. and the rest coming from the rest of the world is probably going to be the pattern for the next 12 to 18 months continuously.

That's super helpful. And then just as a follow-up, could you give us a sense of how things are progressing on your effort to enter the utility-scale market and the evolution of that market as we start to see some evolution on the balance of systems for the electrical elements of these systems just leading up right there?

So we're continuing incremental penetration into the ground mount market, if you will, which wouldn't be classified as utility in terms of that we're not talking about the installation sizes of hundreds of megawatts. But we are more and more installing systems based on the larger inverters that we are introducing and the lower-cost optimizers into more and more projects at the size of 5 megawatts, 10 megawatts, 15 megawatts ground mount installations all over the world. The next step improvement or the next step penetration from our side will be, as we discussed several times, toward the end of this year, beginning of next year with the introduction of an above 300-kilowatt inverter, which will take us a next step in terms of suitability for larger ground mount installations, and we will continue to evolve from there.

And we will take our next question from Mark Strouse of JPMorgan.

Just wanted to go back to the component inventory to Stephen's earlier point. Are you able to quantify that at all or maybe put it in terms of if the supply chain inventory headwinds last for another two quarters or another two years, whatever, at what point does it become even more of a material headwind to SolarEdge?

So, two to three years is a tough question. We are in continuous dialogue, obviously, with the contract manufacturers and the supply base for components. Based on that dialogue, in terms of the projections that we give them and the commitments that they give us, we don't see major issues assuming everybody sticks to their plan, i.e., our growth is the growth that we are expecting. We don't see major decommission. Now this is based on alignment that is done recently and not based on, as you know, live within the crisis and not commitments or alignment that was done prior to the crisis beginning. So what this translates to in our messages is that we have a plan for the foreseeable future that is aligned with the supply base to the component level, not only the contract manufacturing to which we can deliver on the optimistic growth expectations that we see. To extrapolate that two years out and what could happen in the component industry, that's a bit beyond our capability at this point, especially if you take into account these cycles usually don't last that long in terms of the ability of component manufacturers to add capacity within those time cycles.

Yes, sure, makes sense. Okay, and then just lastly for me - not looking for you to name any specific customers, but as you look at your U.S. customers that are providers of leases or PPAs that have maybe safe-harbored in the past. Can you talk about any change in their buying behavior since the ITC was extended a few months ago?

Yes, as you said, I can touch on specific names based on a press release that we issued shortly after our previous earnings call about an agreement that we reached in Sunrun for delivering the Energy Hub to them, and we're very happy in terms of how that renewed relationship is evolving. Part of that is obviously translating into our projections. I don't have full visibility to them and the other large installers in terms of how much Safe Harbor they still might have in their inventory and what type of product.

And we will take our next question from Brian Lee of Goldman Sachs.

Thanks for taking the questions. I had two; one on gross margins. I know you had talked about Ronen a couple of moving pieces here that are kind of pressuring gross margins and the 2Q outlook. Can you help quantify a little bit just some of the logistical costs, what sort of basis point impact it's having because obviously you put up a very good gross margin in Q1 on the solar products. It seems like there is a headwind you're seeing on the logistical cost from quarter-to-quarter. And then mix helped you a lot in Q1. It sounds like mix is still pretty good in Q2 because you're expecting growth in the U.S. to continue to be robust. But can you kind of level set us again? You said in the past sort of what your margin delta is between different regions and between resi and commercial. I know it converged a bit recently, but could you level set us again as to kind of what the margin delta you typically see across some of your end markets and geographies?

As we mentioned at the beginning, due to the fact that there are so many moving pieces to name and to give the effect of all of them, it's relatively tough. I would say that in this quarter, first of all, as I've laid out, if you take the mid-range of our guidance, we are supposed to be at around 37% on the mid-range, which means about 200 basis points of reduction compared to this quarter. This encapsulates the vast majority of all of them because the ocean freight is usually, I would say, not more than 100 to 150 basis points in general, usually, but again, these kinds of expenses almost doubled over the last quarter. But this is something that, again, is changing based on the routes that you're shipping whether you ship more from Europe, whether you ship more from China and Vietnam, and there are a lot of fluctuations there, and you see a relatively large number. The exchange rate differences, of course, are hard to predict. This quarter they were above the usual rate, but at the end, they worked a little bit against us. So again, I think that if you take a new bundle all of the changes in the shipping prices plus the effect of the mix plus the effect of the exchange rate you get to these 2%, and this is the neighborhood not dramatically over this one.

Okay, fair enough. That's helpful. And then just a second question on - there is a lot of questions around the battery storage and the ramp here that you're contemplating here over the next several quarters. I thought in the past you had talked about kind of the ability or at least the confidence around $100 million to maybe $150 million of battery storage revenue resi as you ramp in 2021, obviously, mostly in the second half given the timeline of the ramp. But are you no longer of the view that you can get to that kind of triple-digit millions of dollars of revenue this year, and if that's the case?

No, no, we still hold this view.

Okay. So you're a $100 million plus in the second half of this year on the new resi storage product. Just wanted to make sure that that's still your view.

Yes, and again based on - all according to the ability to ramp and no disturbance on the supply chain. But in general, there is no change. And Zvi mentioned before, everything is on track, and there are no changes to the plan.

And we will take our next question from Maheep Mandloi of Credit Suisse.

Could you maybe just talk about the split of commercial revenue on residential revenues in Q2? And how that should evolve in Q3, Q4? And I'm just trying to understand. You guided commercial should recover in Q2 and Q3. So just trying to see if we should expect higher commercial demand run rate in Q3 versus current levels going forward? Thanks.

Yes. So Maheep, as I mentioned in the comments, our commercial volume in megawatts from Q4 to Q1 grew by about 35%. This was primarily growth in Europe and rest of the world. Our commercial shipments also in the U.S. grew quarter-over-quarter, but to a lesser effect than they grew quarter-over-quarter in the other two regions, as we characterize them—Europe and Australia. At the same time, we began to see also in the U.S. higher installation rates and sales by our distributors and reduction in inventory levels. So we do believe that the U.S. will begin to pick up as well following the pickup that we saw in Australia and rest of the world, not necessarily at that growth rate. We are, and we referred to this a few times in the past, we expected, barring the improvement from the economies related to the pandemic, to begin a pickup in the second quarter. Usually, commercial installations are back-end heavy in the year, so it is a reasonable assumption that the commercial shipments will continue to improve globally and, in particular, in the U.S., as I mentioned.

Thanks for that. And just on the freight cost and thanks for the color on the gross margin impact for that, but I just wanted to understand if the higher freight cost or freight challenges is impacting your, I believe, supply in any of the markets right now or the way to ask is if demand is much higher than what you're seeing out there?

Yes. Demand is strong and becoming stronger. Our logistics operations are complex and global. We manufacture at five sites in multiple locations around the world and we deliver to many countries and optimize continuously based on various elements and that's not a simple operation. I can give you an example in the Suez crisis of a month ago. We had more than 100 containers of product that were stuck in this congestion, some of which were on the actual boat that was blocking the canal and some were at both sides of the canal. Nonetheless, with all of that going on, our delivery dates were intact and our customer deliveries were not delayed because the complexity also gives us many options and a lot of levers to play with. We believe we are pretty good at this. With all the challenges ahead, we believe that we will be able to execute on the demand both from a component availability and the logistics constraints that are out there today.

And we will take our next question from Eric Lee of Bank of America.

Maybe first on just in terms of the channel supply inventory levels versus target. Can you talk quantitatively about how much the extent of the increase in residential solar demand was relative to the extent of the incremental supply you're able to secure post the AC and ASC drivers here in terms of keeping channel supply inventory consistent with yours?

So in general, Eric, first of all, the level of inventory or the nominal level, I think is sometimes not the only number or I would call it factor that is interesting. It's more actually the inventory days that they're holding, which means for how long they can basically supply based on the inventories that they have. Now, in general, what you see is that toward the end of the first quarter, the absolute number or the absolute value of inventory is growing in channels because everyone is getting ready for Q2 and Q3. The more you hear about component shortages in the market, the more you hear about complexities of companies to provide at that time, you see those, I would call it, distributors trying to optimize the level of inventory that they are holding, which is something that costs money in working capital with a desire to get as much stability by simply holding the inventory. So in essence, what we see right now is that when we talk to our distributors, we're very well aligned with them on lead times. As Zvi mentioned, even if there are logistical hurdles, we're able to meet the delivery times, and we're able to communicate them well to the distributors and allow them to understand and decide what is the level that they have. Right now, at least we see normal behavior for this time of the year, and again we do not believe that there is any pull-ins or any deliveries done now just to secure that they have inventories for the rest of the year.

And in terms of power question on storage as you heard the product since the markets in 2Q, can you talk about how you're planning to prepare pretty actively across any potential storage versus solar here, presumably around a lot of expertise and training to install your storage solution given that the teams continue to pretty made by some of your peers out there. Thank you.

So I'm not sure we understood all of the questions, but a big enhancement in the battery is the communication technology and ease of installation. We invested a lot of attention in that in the design of the battery and in particular the way it integrates with our Energy Hub system. So that training is actually being initiated this week toward the installers, but I believe that due to the design and the way it was designed and the simplicity that after some simple installation, most of the installers, and we have many experienced installers, will be able to deal with this with relative ease.

And we will take our next question from Jed Dorsheimer of Canaccord Genuity.

Thanks from Canaccord Genuity. So I guess first question, if we look at, if I look at the five times cost decline in solar in general over the past two decades, from a right law perspective, it seems like technology has kind of led the way. And that does leave the opening or it leaves labor at least from a balance of systems, and I'm just wondering how you're thinking about the reduction of labor cost as a function of either as you talk about three-phase sort of light commercial, if you will, in non-utility or residential sides of things. Is that about lightening - reducing the weight of your inverters? How are you thinking about that value proposition at this point?

Yes, it's an interesting question and worth spending more time than this type of short discussion. It is something that we are paying attention to at many levels, and generally, over the years, it was considered a relative strength of ours. Our position with the large installation companies and some of that strength was coming from a lot of joint efforts to help their installation efficiency, and our - the importance we were putting in it and the willingness to discuss these types of items and work together on how we help them in some cases in our small part. Obviously, the big issue is theirs in terms of increasing the amount of installations that can be done per day or reducing the amount of time for installation. There have been things that have been done over the years in terms of integrating elements that were previously installed separately and incorporating them into the inverter and other elements of reducing time of commissioning and downloading software and things like that. In all of these areas we are investing a lot of R&D and doing that in cooperation with some of the large customers that we work with both in residential and C&I. There are, as you suggest, also opportunities that are more related to the overall balance of the systems of installations, and the direction that things are going more in C&I. We are investing again in R&D and looking at these types of opportunities, and it's an area that we have a team that is focused on. Again, it's not something to get into right now, but we concur that this is an area of growing importance in terms of the growth of the industry and the adoption of these types of solutions around the world.

And then I guess maybe just a longer term, I mean, assuming you'll probably - getting through this tightness, there'll be a decent amount of overcapacity in the marketplace that you’d benefit from. But as you think about the procurement of components, how are you thinking through the competition that increasing around electrification? Because for the past decade or two, it's largely been competing against different solar technologies, and today it's now a competition among EV system design or transmission and distribution of non-solar-based technologies. So as you think through the hierarchy from your system solution perspective and multiple facets to that, how are you thinking about making sure that you have the capacity in a fabless design?

Again, a bit of a high-level question. I'll answer with two elements. First is, from the beginning, our optimizers were based on our ASIC, and we've expanded that level of vertical integration at the component level to other elements of the system that are basically components designed for us and ordered by us. Obviously, yes, we are dependent on—in some cases—not in all cases, obviously—for the same components and it's a trend that we plan to continue and exercise also in some of our other businesses. So the broader topic of the question is indeed, and I think it's a good sign for our industry, the entrance of big technology players that are seeing renewables and solar, and PV in particular, as growth opportunities and are significant opportunities that are here to stay. We welcome that, and I think it's good for all of us. I think we are pretty aware of our strengths and at the same time aware of our weaknesses. Now that we are in the e-Mobility space in some of the areas, it also allows us to compare ourselves to other companies from other industries and realize that if you take the specific topics of power electronics and high efficiency, high reliability power electronics and the ability to mass produce high-quality, high-efficient power electronics, that's what we know how to do. That is the core strength of the company, and we feel good about our capability and talent compared to most companies that we came across, including some of the very well-known names around the world in this area. So that's our strength, and it's a strength that we believe can provide us with a lot of opportunities in the future, and we are focusing on maintaining that strength and finding a way to capitalize on it. And I hope that helped answer the question that you were aiming for.

And we will take our next question from Jim Ricchiuti of Needham and Company.

A question I have is related to storage, given that you're reaffirming your storage revenue targets for this year. I'm wondering how we might think about this in terms of, does this skew the revenue mix more toward residential in the back half of the year and presumably and tell me if this is - if I'm not misinterpreting, but a higher mix in North America? And then I have also a follow-up on your installers.

So not necessarily, especially since we began shipping the Energy Hub, there are many inverters out there that have not yet been coupled with a battery. So it does not mean that every battery that we will be shipping will be going automatically with an inverter at that time, and as a result, leading to that type of tilt—a more dramatic tilt toward residential. Many will, but some will not. So I don't think that this will skew the balance between residential and commercial or between specific geographies as it relates to the solar installations. Yes, the majority of the batteries in the first phase will be coming to North America, so the initial surge in revenue generation will come from North America and then spread to Europe and Australia and the rest of the world.

And we will take our next question from Kashy Harrison of Simmons Energy.

Good evening, everyone, and thank you for taking my questions. So my first one surrounds the supply chain. Thanks for all the commentary there. You mentioned you have enough supply to meet your anticipated demand in the second half of the year. Just curious, does this contemplate any excess demand that may materialize if your major competitor doesn't have enough supply to meet their demand for the latter part of the year?

We were projecting year-over-year growth based on different dynamics that we thought will come through 2021. We don't know - I don't think we know how to quantify specifically if and what type of opportunity will arise out of that dynamic. So we know that we expect growth, and we know that we and believe that we can deliver on that growth. If there will be such a component within that opportunity, we should be able to deliver on it, but I have no way to confirm or quantify something like that.

And we will take our next question from Tristan Richardson of Truist Securities.

Just a quick question on the new product launches, just on the storage side. I think in the past you've said that from a margin perspective, 25% could be a general high-level expectation. Just curious if that still holds, and maybe just the timeframe to get there in terms of what kind of scale you need to see first?

So first of all, nice to talk for the first time, actually. In general, the gross margins that we expected was indeed in the range of 25%, and I think that there are two factors that we need to take into account here. The first one is that when we made this assumption, we believed that there was going to be a relatively sharp ASP erosion in the prices of batteries, which actually did not happen due to the relatively high demand in the market. Therefore, there is an expectation that at least in the short term gross margin will not be there but may be much higher at the very beginning due to the fact that you still need to ramp up their economies of scale related to the way that you ramp up. But we definitely see potential to get there. I think that it's the next layer of potential. Actually, once we have our Sella 2 factory—and this is something that will come in the later part of 2022 when batteries from Sella 2 will start arriving—because at that point we will have our own factory with our own cost and with our own supply chain, meaning that we do not need to leave margin maybe in the hands of a third party as well. We feel that there is achievable capability to get to a higher margin and of course, over the long term, once there is satisfied demand, we believe it will go back to this 25%.

And we will be taking our last question from George O’Leary from TPH & Company.

Just kind of a big picture question from me related to e-Mobility. I realize there is the Fiat E-Ducato that you guys already have in the bag. But just qualitatively, what is the pipeline for incremental auto OEMs that you guys see? And how has that been affected by kind of the recent events that we've seen in the auto space? Is the pipeline still growing, or are people kind of hit the pause button as they're dealing with their own supply chain issues? Just curious for any color you could share there.

I think we mentioned our investments in this segment are long-term, and the growth is going to be gradual and long-term. So we don't have in our pipeline for the—and we said this in the last earnings call—in the late next 12 or 18 months, an equivalent in terms of scale and visibility like the Ducato. So we have a series of smaller, shorter-term opportunities and longer-term bigger opportunities that we are working with and working on, and we'll share them as they evolve and materialize. One of the results of that is we are not really dependent on these types of current events and constraints that are somewhat disrupting the e-Mobility industry, and we are more there to execute and ride on the long-term path of this segment, which is showing or where the potential is growing every day. We don't have anything big other than the Ducato in the next years. As a result, these events are not going to impact us positively or negatively in the next year or two, year-and-a-half.

Thank you. And I will now turn the conference back over to our speakers for closing remarks.

First of all, thank you everyone for joining. We are taking this call for the first time in the last year-and-a-half from our California office, enabling us for the first time to travel out of Israel to here and in recent weeks, we've been able to visit our factories in Italy and Korea as well. So we are encouraged by the direction that that is going and wish everyone else in our industry and other industries health and success and to come back to normal as soon as possible. Thank you for joining.

Thank you, ladies and gentlemen, for your participation in today’s teleconference. You may now disconnect.
