Thank you, Erica. Good afternoon and thank you all for joining us on our conference call. Given the unusual circumstances surrounding the COVID-19 pandemic, I will take the opportunity during this call to focus most of my discussion on how we are managing business in light of the situation and provide insight into the coming quarter. Starting, however, with highlights of our first quarter results. We concluded the quarter with record revenues of approximately $430 million. These revenues include a record quarter in our solar business of approximately $408 million. Overall, this quarter we shipped five million power optimizers and 202,000 inverters. This quarter was in line with our guidance and expectations for continued growth and included highlights, which is a record quarter for revenues in Australia and North America, and record commercial shipments by megawatt both globally and in North America. Obviously, in the current environment, there are bigger question marks about the future and I would like to focus on that rather than on the achievements of the quarter that has ended. At the time of our Q4 earnings call in early February, COVID-19 was an event concentrated in China and the concerns and question marks raised were about the ability to supply. At the time, we communicated that thanks to early measures we had taken, we expected no significant supply issue and as our results show we executed on this message. Since then the pandemic has spread to various regions of the world in varying levels of severity. Due to our global spread and in particular, our large operations in the early and significantly hit locations like Korea and Italy, events, on the one hand, challenged the company and management but on the other hand, these events gave us early insight into the dynamics, which has now affected most of the world. We learned and implemented early on the tools and procedures needed to keep our workforce safe and made decisions such that by the time the virus impacted the United States and countries in Europe, we were able to adjust rapidly. In addition, we have been sharing this know-how with customers, distributors and installers. Through March and April, we conducted more than 340 webinars attended by more than 25,000 people covering subject matters ranging from news about SolarEdge products to how to sell solar systems remotely and other topics of interest for solar installers. In some webinars, we hosted third-party experts who shared information aimed at enriching the knowledge and capabilities of our customer base of approximately 30,000 global installation companies. On top of the customer engagement activities, only visibility of the COVID-19 impact enabled us to prepare all of our global service manufacturing and R&D centers, such that work throughout the period continued with minimal impact other than challenges related to the inability to travel internationally. Moving onto the business environment. In order to assess market dynamics, we are closely tracking installation rates of our products through our monitoring portal globally and per country. While this is an important indicator, it provides only part of the system as it is not directly indicative of new solar system sales by our installers; however, we do think it is a helpful tool to foresee market demand. During the COVID-19 impacted months of March and April, installation rates of SolarEdge products outside of the U.S. increased by 15% compared to the same period last year. Starting from Europe on a potential basis, installations in Italy, historically a strong SolarEdge market declined by 47%. In the last three weeks, however, the installation rates there have started to rise again. In the Netherlands, where we are the market leader, our product installations were flat when compared to March and April of last year. The most positive data comes from Germany where our product installations during this period were up 42% compared to the same period in 2019. This is a result of the lower COVID-19 impact in Germany, coupled with market share gains related to our end-of-2019 release of the three-phase residential storage inverter. In the U.S. during the same period, the installation rate of our products declined by 16% compared to March and April of 2019. In the U.S., where the impact of COVID-19 hit later than in Europe, the decline in installation rates in April alone was 33% and the number of daily installations has now stabilized for the last few weeks. Additionally, we are in constant contact with distributors and installers to monitor their inventory levels as well as review our new solar system sales in their markets. Generally, the sentiment in Europe and Australia is more positive than that in the U.S. However, the data vary significantly from country to country and demand from our installers. Similarly, it is difficult at this point to identify a clear trend between residential and commercial. However, we believe that our global presence in diverse revenue streams both geographically and in multiple segments positions us well to minimize the impact of the pandemic on our business, but it will impact business and this is reflected in our second quarter guidance. While it is difficult to see how long this downturn will last, we are preparing for various scenarios, including a potentially slower third quarter. Preparations include careful scrutiny of our spending and management of operations. Already, we have made expenditure adjustments, including the review of all of our variable expenses. In addition, effective April 1, our senior executives voluntarily reduced their base salaries by 20%. The above measures combined with our strong balance sheet will be used to continue and push and even accelerate the strategic projects that we shared with you during and since our Analyst Day. This month we are beginning to shift in North America our new HD Wave-based energy hub inverter which provides storage and backup offerings compatible with third-party batteries and is the basis for our complete solution, which will be coupled with our own batteries scheduled for release towards the end of the year. Later in the quarter, we will start shipping our new commercial inverter with added safety features and higher energy density, followed by a ground-mounted dedicated power optimizer with higher power density and better economics. Our focus on long-term R&D projects continues as planned with a broad pipeline of products and capabilities for residential, commercial, and utility applications. On the non-solar front, our lithium-ion business program in Korea is stable and continues to deliver revenues while utilizing our entire manufacturing capacity. Activities with the expansion of the two-gigawatt factory are on the way as planned. In the E-Mobility business, qualification by a Tier 1 automotive manufacturer of our full electrical powertrain solutions continues while we deliver increased numbers of units to accelerate the validation process. In summary, we are pleased with the results of the first quarter and while we expect a challenging period in the near future, we are confident that the core strengths of our company in technology and institutional feasibility combined with our extensive product roadmap will enable us to come out of this period even stronger. With this, I hand it over to Ronen, who will review our financial events.

Thank you, Zvi and good afternoon everyone. As always, my review includes 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. In addition to providing explanation and color around our Q1 numbers, I will provide as much insight as possible into the financial impact we're seeing that COVID-19 is having on our business. While we will make every effort to provide this insight, as you well know, and as you all have seen over the last few months, circumstances surrounding COVID-19 can change rapidly and are outside of our control, and so my inputs on this call are, of course, based on what we are seeing at present. As for the first quarter results, total revenues were $431.2 million, a 3% increase compared to $418.2 million last quarter and a 59% increase compared to $271.9 million for the same quarter last year. Revenue from the sale of solar products was $407.6 million compared to $389 million last quarter and was driven by growth in the United States and the rest of the world. U.S. solar revenues grew this quarter to $246 million representing 60.3% of our solar revenues. In U.S. revenues included safe harbor revenues of $54.1 million, a slightly higher number than we originally planned as we expedited some of these deliveries over non-safe harbor shipment to avoid delays related to possible border closures. Solar revenues from Europe were $122.3 million or 30% of our revenues. Q1 revenues generated from outside the United States and Europe were $39.7 million, a record number representing 9.7% of our solar revenues this quarter, most significantly from Australia, in which we had a record quarter. On a megawatt basis, this quarter we delivered 926 megawatts to the United States, 641 megawatts to Europe, and 283 megawatts to the rest of the world. Residential products represented 56% of our megawatt shipped and commercial systems were 44%. This quarter, our top 10 solar customers represented 62% of our quarterly solar revenues, a decrease from the last quarter, and one distributor accounted for more than 10% of revenues. Blended ASP per watt decreased this quarter by approximately 4.3% compared to the last quarter due to a change in the customer mix and devaluation of the euro and Australian dollar against the U.S. dollar. This quarter revenues from our non-solar products were $23.6 million, mostly related to the sale of lithium-ion battery. GAAP gross margin for the quarter was 32.5% compared to 34.3% in the prior quarter, and 31.7% in the same quarter last year. Non-GAAP gross margin this quarter was 33.6% compared to 35.5% in the prior quarter and 32.8% in the same quarter last year. Non-GAAP gross margin for solar activities was 35% compared to 37.8% in the last quarter. Last quarter our solar margins benefited approximately 300 basis points due to one-time effects related to the implementation of cost reduction measures to our warranty accrual. Excluding this one-time benefit, the solar business gross margin slightly increased as a result of lower than anticipated air shipments, which represented 215 basis points this quarter. These lower-than-anticipated air shipments were mostly attributed to the increased capacity we built in the last quarters. The lower-than-expected air shipments were partially offset by a change in the product and customer mix and holiday labor rates paid to contract manufacturers who continue to work during Chinese New Year and the subsequent lockdown in February and early March. We expect our air shipment expenses to be much lower in the second quarter of 2020. Non-GAAP gross margin for our non-solar activities was 9% compared to 4.9% in the previous quarter. The increase was a result of a strong margin from the sale of our lithium-ion batteries offset by lower margin in the machinery and E-mobility groups. Moving to our operating expenses; in total, operating expenses for the first quarter were $72.2 million or 16.8% of revenues compared to $92.7 million or 22.2% of revenues in the prior quarter, and $258.1 million or 21.4% of revenue for the same quarter last year. On a non-GAAP basis, operating expenses for the first quarter were $66.3 million or 15.4% of revenues compared to $63.1 million or 15.1% of revenue in the prior quarter and $48 million or 17.7% of revenue for the same quarter last year. Our non-GAAP solar operating expenses as a percentage of solar revenues was 13.5% compared to 13.8% last quarter. This quarter, GAAP operating expenses included a non-recurring income of $4.9 million that was collected from the major selling stakeholder of Kokam and indemnification for settlement of a pre-acquisition claim. As part of our reaction to the economic slowdown that we are already seeing from COVID-19 and as Zvi mentioned, we have reviewed carefully our business plan for 2020 and implemented certain cost-cutting measures including a reduction in executive management base salary, general halt on recruitment, and freeze on salary increases which were planned for April. In addition, we are eliminating workforce redundancies and adjusting our headcount to the reduced level of activity in certain regions as well as renegotiating other expenses such as rental agreements and consulting services. Some of these adjustments are still ongoing, and the effect will be seen in our operating expenses for Q2 and Q3. Our GAAP operating income for the quarter was $67.8 million compared to $50.5 million in the previous quarter and $28 million for the same period last year. Non-GAAP operating income for the quarter was $78.6 million compared to $85.3 million in the previous quarter and $41.2 million for the same period last year. This quarter, non-solar activities resulted in a non-GAAP operating loss of $9.3 million compared to an operating loss of $8 million in the previous quarter, driven by operating losses in the UPS machinery and E-mobility divisions and offset by profitability of the lithium-ion businesses. Financial expenses for the quarter were $16.6 million compared to financial income of $11.1 million in the previous quarter and a financial expense of $6.2 million for the same period last year. The decrease is a result of foreign currency changes resulting mostly from unrealized exchange fluctuations, and the accounting treatment of intercompany balances and intercompany loans provided for the acquisitions in Korea and Italy. The impact of these unrealized intercompany exchange rate expenses on GAAP and non-GAAP net diluted EPS was $0.24. Tax expense was $8.9 million this quarter compared to $9.2 million in the prior quarter and $3.9 million for the same period last year. Our non-GAAP tax expense was $12.5 million compared to $10.4 million in the prior quarter, and $4.9 million for the same period last year. GAAP net income for the first quarter was $42.2 million compared to a GAAP net income of $52.8 million in the previous quarter, and $19 million for the same quarter last year. Our non-GAAP net income was $50.7 million compared to a non-GAAP net income of $87.4 million in the previous quarter and $32.9 million for the same quarter last year. GAAP net diluted earnings per share was $0.81 for the first quarter compared to $1.03 in the previous quarter, and $0.39 for the same quarter last year. Non-GAAP net diluted EPS was $0.95 compared to $1.65 in the previous quarter, and $0.54 in the same quarter last year. Our non-solar business generated $0.23 non-GAAP diluted earnings per share loss. Turning now to the balance sheet. As of March 31, 2020, cash, cash equivalents, bank deposits, restricted cash deposits and investments were $558.7 million compared to $467.5 million on December 31, 2019. During the first quarter of 2020, we generated a record $107.7 million in cash from operations. We are happy to be in such a strong cash position with practically no debt during these times. AR net decreased this quarter reaching $235.7 million compared to $298 million last quarter. DSO this quarter in the solar business was 62 days, a decrease from 65 days last quarter. Naturally, in light of the financial situations in the market and our global operations, AR in collections are a major point of focus for us. Over the last few weeks, we have closely reviewed our AR balances and the financial stability of our customers. In some cases, we are selectively examining and providing longer credit terms to customers in order to support them in this period. We will continue to examine the creditworthiness and strength of our customers even more cautiously these days, and we will carefully consider adjusting credit allocations as needed. As of March 31, 2020, our inventory level net of reserves was at $198.6 million compared to $170.8 million in the prior quarter. Most of this increase is related to raw materials of our factory accumulated in anticipation of component shortages and supply chain disruptions from COVID-19. These raw materials will be used for manufacturing in the next quarters. Additionally, approximately $38.2 million of our inventory relates to non-solar inventory, the majority of which is raw materials held in Kokam. As Zvi explained, we expect that the effect of COVID-19 will impact our business in the United States and to a lesser extent in Europe, and will result in reduced revenue in the coming two quarters. Given our size and scale of operation, adjusting our manufacturing and inventory levels to the new level may take one to two quarters. Moving now to the guidance for the second quarter of 2020. Before outlining our guidance, I would like to remind you that the evolving impact of the COVID-19 pandemic is unprecedented and that makes it difficult to predict with confidence its impact on the company's business for the next quarter and for the rest of this year. Our guidance for the next quarter includes the anticipated impact of the COVID-19 pandemic on our businesses, as viewed today. In our Q4 earnings call, we told you that approximately 7% of our Q2 2020 orders were already received. Since then, we have of course received additional orders; however, we have also received requests for rescheduling and/or cancellation of orders. Our Q2 backlog is large enough to exceed the guidance we have provided and our manufacturing capacity and inventory will facilitate the delivery of those orders. We expect revenues for the second quarter of 2020 to be within the range of $305 million to $335 million. Revenue from the sale of solar products is expected to be within the range of $285 million and $315 million. We expect growth margins to be within the range of 30% to 32%. Growth margins from solar activities are expected to be within the range of 32% to 34% reflecting a higher percentage of revenues from Europe, which is characterized by lower margins. I will now turn the call to the operator to open it up for questions.

Thank you. And first we'll go to Mark Strouse with JP Morgan. Your line is open.

Thank you very much for taking my questions. Appreciate it. Ronen, if I could just start with the guidance, the revenue range is wider than usual, not surprising given everything that's going on, but can you just kind of talk about what needs to happen to come in at the high end of that range versus what might happen at the low end?

So in general, and as I mentioned, we are sitting today on a backlog that is sufficient to fulfill and basically cover the entire range that we have provided. However, during the last few weeks, we have seen requests for either rescheduling and cancellations, and at the same time, we're also seeing customers that are either struggling or we are afraid that they will struggle with payments in terms. As such, even if we have orders that were already received, already booked, already in our orders book with a defined delivery date, we are looking at every order, we talk to every customer and we make sure that we are not only providing whatever was already ordered but actually we make sure that we are not providing customers with goods that either do not need or at the same time that we're providing credit to customers that we are a little bit afraid that they will not be able to collect. Again, the orders are there, but the situation is changing rapidly. I think that every day in almost every week you see restrictions or continued restrictions. In this case, we almost as usual decided to take the more prudent guiding approach given the range that we see a bit recently.

Okay, that's helpful. And then kind of related to that, just your sense given your conversations with your customers regarding channel inventory, maybe if you can talk about what that looked like in late February and early March versus what that looks like today and any kind of trends that you're seeing with sell-through for those distributors?

So, of course, as Zvi mentioned, what we see around the world is very much different between country to country, continent to continent, and even customers to customers. So, I'm not sure that I can generalize my entire answer to all of the customers that we see and we talk to. I would say that in general, we usually see 60 days to 90 days of inventory levels within large distributors; usually, smaller distributors are holding smaller amounts because of the working capital needed to be. Usually the way that they're measuring these 90 or 60 days is based on the forecast, they see in front of them and what they expect to do. I would say that overall, when we deliver the product, the inventory level on the absolute value may be very similar to what we usually see within the customers, they do not carry much more on the dollar volume. The time that they need to consume these inventories may change. And again, it varies. But I would say that in Europe, we will see almost regular days while in the U.S., at least right now with some of the shelter-in-place restrictions, some of the distributors have much higher than the usual days of inventory than they typically carry.

[Operator Instructions] And next we'll go to Colin Rusch from Oppenheimer. Your line is open.

Thanks so much. We've been monitoring inconsistent lead times and resource availability. Can you give us an update in terms of where you're at in terms of general lead times on products that are extended a little bit versus the rest of your portfolio?

So, first of all, in the last few quarters, we saw lead times extending as naturally the business grew much faster than our ability to manufacture and ship. For the beginning of the quarter, I think Q2 our lead times are almost similar to what they were before, and in some cases it was even close to 10 weeks, mostly related to the fact that we decided to avoid air shipment and we're shipping most of our products using ocean freight. I would say that in general, what we're aiming to do is to be at around six weeks of lead time once we are able to replenish inventory to the desired levels using ocean freight in all of the territories in which we operate.

Great. Thanks so much. And I know the CapEx with the battery factory, can you speak to what level we should anticipate for this year as a total number and then equipment availability? Is there any delays or parts of that project that you're going to delay at this point given the COVID-19 situation?

Can you speak again? The line was not really good. Your question is mostly related to the?

The Korean battery factory and your build-out on capacity there. What's the expected total CapEx? Are there any equipment procurement issues that you're looking at right now, and if there are any delays regarding that project?

So first of all, we're very happy that actually we see that the project is continuing as scheduled despite the fact that Korea was one of the first countries that was affected by COVID-19. This project is scheduled and continuing as usual; the plan is to have our 2-gigawatt factory able to start manufacturing at the beginning of 2022. The cost associated with this project is about $95 million, including the land that we actually just acquired right after the quarter. We acquired the land, the building and the machinery, and all of these expenses and equipment will be bought and deployed over the next 18 months. We do believe that right now based on the schedule, we do not see a delay. We do believe that the continued work that we need to do when it comes to negotiating terms on machinery, and some of the machinery is coming from outside of Korea. This will, of course, depend on the ability to travel to ship and have the technicians coming in but at least at the point we are today, we do not see delays for these 2-gigawatt factory beginning to deliver in 2022.

[Operator Instructions] And next we'll go to Maheep Mandloi from Credit Suisse. Your line is open.

Hi, thanks for taking the question. Just on cost controls which we announced in the quarter, can you talk about when we could see the benefits in gross margins, either in Q2 or the second half of this year?

So, the cost control and the margin. Let’s first differentiate because a lot of the cost control is also related to the operating expenses and not just to the margins themselves. Our aim is to be by the end of Q2 at the run rate of operating expenses that were similar to what we saw in Q3, 2019, and this is around $58 million to $59 million a quarter of operating expenses. Again, since we're implementing these measures, we're already in the beginning of May. Of course, not all of this will be realized in Q2. Some of it will come in Q3. When it comes to this margin because the activities that we do there are a little bit hard to predict because they are dependent on what we achieve but also dependent on the revenue, the mix and the customer mix so it's geographic mix and customer mix. For example, in the second quarter of 2020, a substantial part of our revenues will come from Europe and gross margins in Europe are lower than gross margins in the United States. So despite the fact that we have already cut costs in our cost of goods sold in our operational departments and costs related to manufacturing components and shipments, the fact that we're delivering substantially higher volumes into Europe, which is characterized by the lower margin, will take away a little bit of these effects. This is what you see, actually in the guidance that we give. All in all, on OpEx, we will go back to about Q3, and when it comes to gross margins, the magnitude of sales to each and every territory will determine what the numbers will be.

Thank you for the clarification. I just want a small housekeeping question then on the Safe Harbor; could you clarify how much Safe Harbor do you expect in the Q2 revenues? I think previously you said you might have something in April for Safe Harbor. The last question, then I'll jump back, is just on the other product launches. You touched upon the battery product but can you talk about the Smart Modules security scale and the Gen4 optimizer? Thank you.

I'll talk first about the first part of the question and Zvi will answer the second. Safe harbor orders for the second quarter are approximately $17 million. These are important to say that these are not just, of course, residential safe harbor orders but also commercial, but all in all, it's around $17 million. Now, regarding new products, Zvi maybe.

As I mentioned, the residential battery as we said all along is scheduled for the second half initial shipment. We are on schedule with that. We are approaching the certification service that takes place in multiple places around the world, so there is still some question mark on how much we will be able to ship our batteries around the world. That's the only risk factor on meeting the schedule during the second half of the year. Smart Modules we already delivered today. It's not a huge part of the business, but we are delivering every quarter embedded Smart Modules of SolarEdge optimizers already today, and we expect this to ramp while it's still a small portion of the business. Optimizers, I'm not sure in particular to what you are referring. As I mentioned, we have a new optimizer that is the high power optimizer specifically for ground mount installations especially focused on the community solar market in the U.S. That optimizer will begin to ship in the next few weeks or before the end of this quarter. On the standard residential and commercial optimizing enhancements and improvements being introduced continuously. So there is no specific new generation that is intended in the next few months.

Next, we'll go to Philip Shen from ROTH Capital. Your line is open.

Hi, everyone, thanks for the questions. Looking beyond Q2, I was wondering what kind of visibility you have into Q3. How much, for example, of Q3 may be booked? How do you expect potential margins to trend? I know you're not providing official guidance, but if you can provide any color on that, that'd be great.

So literally, again, it seems that visibility is already problematic for Q2, and Q3, of course, is much more limited. I would say that we have limited feasibility. We talk to all of our customers constantly. We see the signs in each country and we are following up very closely with all of our customers and their inventory levels. But I think that the question here is not just what they have but actually what is going to happen to the installation rate itself during the second quarter. Therefore, although the visibility that we have or the level of transparency that we have has been very open and good, the ability to predict Q3 is problematic right now because I think that neither us nor the customers know how much of their inventory will be consumed. This is why we talk about this limited visibility. Now, when it comes to the margins themselves, this will come mostly due to the fact of what will be the mix between the geographical shipments that we will do. We continue to do cost reduction on the cost side on a continuous basis. Of course, as we mentioned before, as Zvi mentioned, we are working all the time to do it, and actually this time in some cases, we're even accelerating those but of course, if you see different mix in different countries, this will affect the margins as well. I would say that I don't think that we can say anything substantial right now about the upcoming quarter itself and the levels, but I can tell that we are following very closely and we're in constant dialogue with our customers to understand their businesses.

Great, thanks. I believe you may have indicated for Q1 that the ASP may have been weak because of mix but I think the U.S. mix went up and U.S. typically has a higher ASP and greater concentration in residential. Can you provide a little bit more color on why the ASP in Q1 was a bit weaker and to what degree may have this been impacted by some competitive dynamics that you guys might be experiencing?

So I think that this was not actually related to much to the competitive environment. It is mostly due to the fact that in Q1 Safe Harbor deliveries were made due to the fact that again and even expedited that we were very much concerned about closures of borders by the end of the quarter, and therefore we decided that we expedited whatever we can in order to avoid these and actually to meet the very strict delivery times of the safe harbor. Naturally, that means that a higher portion of our U.S. revenues came to date from larger customers, and again, naturally larger customers get larger discount rates that were pre-negotiated and known for a longer time. So here it is really more of a mix issue rather than anything related to changes in pricing or pricing environment during this quarter.

Next, we'll go to Jeff Osborne from Cowen and Company. Your line is open.

Good afternoon. Excuse me. Ronen, I was wondering if you could walk us through the gross margins. It's been asked a couple of times, but more specifically the guidance of solar going from 35 at the midpoint to 33. I think you called out a 215 basis point headwind for air shipments. I would assume that that goes to zero. It looks like there is about, at the midpoint, a little over 400 basis points. Is it a safe assumption to say that Europe generically speaking is always 400 basis points lower margins or is it mix or are you using price in Europe to try to gain share? That magnitude was a little bit higher than I was thinking.

Yes, here again, the main effect in Europe, and I will give you even the specific numbers. As we mentioned several times in the past, when we started to actually price products in Europe and the United States, the prices were about the same, but the exchange rate of the euro to the U.S. dollar was approximately $120 per euro. Today we're talking about a much lower rate. Actually, over the last 12 months alone, the euro devaluated by 2.8% against the U.S. dollar. I can tell you that as of today, the difference in average -- the difference between Europe and the U.S. in gross margin is about 450 basis points. Now, this quarter, the main effect that you see is that there is a substantial shift into Europe which is traditionally much stronger in the second quarter and the third quarter, and this move into Europe is, of course, pushing this gross margin down. In addition to this, in Europe, you see sometimes installations that are more heavier towards the commercial products and in the commercial products, and especially the larger products within the commercial portfolio, you have also lower gross margins compared to the residential U.S. market, and this is why you see the effect. This is entirely coming from mix due to geographic and segmental shifts.

And next we'll go to Brian Lee from Goldman Sachs. Your line is open.

Hey guys, thanks for taking the questions. Hope everyone is staying safe and healthy. I guess, question on just the guidance, Ronen. You mentioned April -- or Zvi mentioned April was down 33% in the U.S. but then stabilizing at those levels. But I also think you mentioned Q3 could be slower later in the call. I might have misread or misinterpreted, but are you actually expecting Q3 to be worse than Q2? And then, if not, what sort of data are you looking at to consider Q2 the bottom there?

So maybe I'll clarify what exactly the data we are looking at. We are looking at the rate of installations of new systems, almost every day new SolarEdge systems across every country, and actually even in every state. And we compare that to the rate of installation of new systems a year ago. What I mentioned is that while in Europe and across the world during March and April, actually more SolarEdge systems were installed this year than were installed last year during the same period. In the United States during April, there were 33% less installations of new SolarEdge systems compared to April of 2019. By the way, this will vary significantly by state. Actually Texas was more than a year ago, and California is down a bit more compared to a year ago, and you look at this as every single state. That is giving us an indication on the general level of business, and when we think inventories at the distributor are not rundown and they will begin to either bring in new orders or as Ronen mentioned, the reduced risk of requesting to push out or cancel orders. That is what we're basing our Q2 guidance on. Visibility for Q3, as Ronen mentioned, is very limited, especially concerning the United States. Generally, in several markets around the world -- several big markets around the world, there is a sentiment of business as usual. We just have to wait and see if that carries out to Q3 as well. In the U.S., I think it's very volatile right now; the business is down significantly compared to a year ago, and it's very early to predict what will happen in Q3.

Okay. Fair enough. We are shifting gears a little bit here, I think, on the safe harbor split here, just a question around the $75 million. You guys had originally guided for, I think, last quarter, Ronen, you had said evenly split between Q1 and Q2, roughly speaking. I know you pulled some forward into Q1 here, but it seems like if you hadn't pulled that $17 million or so from Q2, you would have come in about $10 million below the revenue guidance range for the quarter. Just wondering what drove that dynamic or is it all production issues at the end of the quarter or were there other issues? Because I would assume that given you gave the guidance in late February, you had volume demand pretty much locked up for the quarter. So just wondering where that slippage might have occurred and if you're recapturing that volume in Q2 or if that's some of the rescheduling and cancellations you're seeing?

Well actually, it's neither. The situation was -- and again, we need to understand now how the end of March looked in China. At the end of March, it was almost impossible to ship anything outside of China. Ports were not operating fully. Airlines almost entirely stopped flying into China and bringing -- in one case, I can even tell you that we chartered an entire plane to fly products from China into the United States. So in this case, we did not actually decide that we wanted to pull in the orders to meet the revenue guidance. It was the fact that we decided to prioritize Safe Harbor shipments over non-Safe Harbor shipments in order to make sure that we are meeting the delivery times of those Safe Harbor shipments that needed to be around no later than April 15. So in this case, revenues will be approximately the same. We simply took all of the capacity that we could have and we could send outside of China before the end of March. And in this limited and capped capacity, we decided to prioritize Safe Harbor shipments.

[Operator Instructions] Next, we'll go to Mike Cikos from Needham & Company. Your line is open.

Hey, guys. Thanks for taking the questions here, and I apologize if I missed this. I'm juggling between a couple of different calls. I just wanted to come back to some of the supply chain constraints that you guys saw. Can you give us more color with respect to how those constraints are as we stand today, and whether or not the constraints -- once those bottlenecks are past you, are you looking to help your distributors build up the appropriate level of inventory in the current demand environment to help reduce your expenses on the air freight shipments?

So just to clarify, we manufacture in several sites. We manufacture in China, in Vietnam, and in Hungary. Actually, we don't see any supply constraints right now, and we are able to deliver on all orders that we received. What we are doing is instead of air shipping, we are ocean shipping products and building inventory gradually. But we are currently able to supply all demand, and we're looking at the inventory levels of distributors very closely and making sure that no one has any shortage of parts to meet demand.

Okay. Thank you for helping me out with that. And then the follow-up I have for you, with respect to the cost-cutting measures that you guys are taking, can you help us better understand how much of this is temporary? Just because I have to imagine once things start to recover, you guys will be going back into growth mode from the current run rate. So just trying to get a gauge of how quickly these expenses may come back on as demand starts to recover.

So being veterans of cyclical business coming out of the semiconductor industry, looking at this type of event as a short-term downturn, and this not being certain for how long it will go, we look at the items of R&D that are temporary and easy to recover when the business recovers. It’s typically activities that are directly related to the level of operations, and typically, not any type of critical capability or skill that will be difficult to supplement. So we examine the operation entirely, identify those types of opportunities, and those are the cost-cutting measures that we implemented. When the business recovers, we will be able to recover that activity quickly.

And at this time, I will turn the call back to Zvi Lando for closing remarks.

Thank you. In summary, I think it's appropriate to point out that we have entered this pandemic not only as a strong company, but in a strong industry. Smart energy and solar in particular has proven an excellent investment for home and business owners, and I believe that the demand for solar in a climate and world where backup and energy independence is growing in importance, we will continue to evolve. Recent events have proven not only for SolarEdge but through our competitors and colleagues that this industry of mature and conservative market is in an extremely challenging period. Thank you for joining us on the call today.

And that does conclude our call for today. Thank you for your participation. You may now disconnect.
