Are they telling you they have now fixed the issue? SE phone support is broadly OK if you can get thru. You can sleep easy at night knowing you and your family are safe without any risk of a fire on your roof. It may not be their fault but that's a good way to get action. We've just had our solar system reinstalled on our new house ( knock-down rebuild) Since it was reinstalled we've had nothing but problems. Doesnt it excite you? Just remember when you are buying solar, its best to understand what you need. My Frankston Vic solar system was installed at the end of May 2018 with 16 x LG Neon R 360W panels, 16 SolarEdge DC Optimizers and 6kW SolarEdge HD Wave. This will result in5,464 kWh of solar energy coming from the 3.5kW system annually. Can you recommend the optimizer brands flexible and reliable to use for different brand inverter with or without panel monitoring option? A support phone call needs to be made if you want action at all. I think you are based in Adelaide so Arthenius's equation would come into play as I stated in this blog. i know you're located in qld and therefore not an ideal install option, but any suggestions as to what to get would greatly be appreciated. Your privacy is important to us. SolarEdge ticks a number of the boxes I'm looking for, especially the small size of the inverter. Each had similar statements. Get the latest news and analysis in the stock market today, including national and world stock market news, business news, financial news and more Those seem to be the most common along with Jinko solar panel systems or LG panels coupled with SolarEdge inverters. Therefore, it makes more sense to just buy more solar panels for a given power requirement. Cheers, Hi Mark, Im planning to get a 6.48KW Sunpower X22 system with solaredge 5KW hd wave with p500 optimisers. Hopefully my installer can resolve this quickly. The installer is no longer responding to my emails or text so Ive logged a job with SolarEdge but nothing has occurred. Dear Marc! Would think that would be true for most but I don't know the market from an installer point of view. To be clear, I was not saying that. I have 41 300W panels with a Solaredge SE 10000HJ-US inverter unshaded in so CA. Steer clear. Learn more, 2022 Climatebiz All Rights Reserved Twitter YouTube Facebook, Master's degree in Electrical Engineering. You have summed up my main concerns with SolarEdge perfectly. Have you made a decision yet? I'm guessing you didnt read the blog if you are considering SolarEdge! Each panel has its own optimiser which stablises the DC current so it will automatically shut down if the DC exceeds a dangerous level. although reading forums is useful, inherently i found contradictory opinions for all components. I believe it's very unusual - possibly a one-off. Yes, you install minimum one panel in shade, so you will have a minimum of 7 panels on sun and 1 in shade, and at this point your system may lose perfomance. They eventually replaced all three optimisers, (albeit one by one). SolarEdge is at the eve of offering a whole new swag of technically complex products. For example, a friend in Darwin has a significantly worse failure rate than mine. If he is, Ill let him know a bad local review of his company is coming from me. its a firm no. Botched automatic firmware upgrade? It is not that tough to figure this out nowadays, given that there are a handful of decent solar calculators out there. We have been accused of installing them incorrectly, but nobody has suggested how we installed them incorrectly. Adjacent is one of the worst examples. I rang and emailed my installer and messaged SolarEdge (who still havent replied) as it is a warranty issue. In fact, look at the waiver I mentioned in the blog: They obviously trust our design and install capabilities. Hello, can you please provide a contact to Laszlo Suranyi who also has the SolarEdge error 8x10? (only 4 months). The voltage of all the panels add up to 380 volts and 2.2amps. Thank you for your research and informative article. That it needed to dry out then it would start working again Ok, Not impressed. If they mapped the panels on the monitoring platform properly, you could usually tell which one failed. Voltage never stays at the same. Interesting Leon. Which one would be preferred? Curious why the new Enphase IQ series or AC modules would not be the ticket to avoid Solaredge issues all together. Optimisers work on a string level by increasing or decreasing the voltage on individual panels so that the current in each panel in that string is the same. Have you heard of this concern or have any knowledge of this concern? So P404 what would help to solve this problem is completley useless because of its lower Isc value .. Why, why we need P300 ; P370 ; P404 ; P500 ; and now the newest P505 ? Have you got a SolarEdge system? I would also suggest if MPV tediously looked at every panel's production (not just alerts), they would find failed optimisers. Hi Zeus. Would be nice to know what broke, how they want to fix and why beforehand. Do some installers just have good luck? They said something about the fault occurring after heavy rains. Is it an extra cost for the top level monitoring software package. I have found out that I have 750 V DC to my SE17K inverter in Sweden with 3 phase system. 3/. I have just been advised that this is the last time they will replace it and if It fails against will need to do a home insurance claim. (I believe they do most of Victoria). The P404 is about $5 more expensive that the P370. Thanks for your edifying blog - it's very considered, detailed and filled with useful information. My second theory relates to monitoring. An interesting although relatively anecdotal observation that an industry friend recently made: the companies that defend SolarEdge reliability have often been installing them for less than two years. Hi Lawrence. Hi Mark, I am reading this from Cape Town South Africa from a company called Smart Energy SA. I have a 40 panel system (LG "R" 350 panels) in two strings, one 22 and one 18. I've had a 70% failure rate in just 8 years. Is there any days that it is not the same? Its position insensitive: you can place it in any position, unlike the traditional flooded lead acid battery, which must always be upright. However for some reason the phone support always appears to have LOOOOOONG queues no matter what time of day. So yeh, wholesalers should stock up and we should all more often use 404's for $5 more. With this youll get long lasting warranties and the safety features of SolarEdge without any risk of fires of DC on your roof. We have also seen a rise in what SolarEdge considers to be a "Thermal Event" requiring an initial site visit to document that some part of the inverter has "fried". I am going to build a house and looking into different things I need to set up ready for Solar, I will be putting 3 phase on to give more flexibility. I must tell you that each one of these farms is a 100KW block so there are 50 such blocks. i had to combine the two stings into one to get them all to work the whole day. I have a 22 Kw install with 33 SolarEdge P700 Optimizers (1:2) serving 65 LG 335 watt panels. SolarEdge has claimedelectrolytics only last an average of 10 years, and by using film capacitors they significantly increase the expected life of the inverter. Is 380 V on extra design problem with a smaller design window than with 750 V for voltage/current limit problems and so on? My contractor is reputable and has been around for a long time and their performance guarantee will reimburse me for my grid use until the inverter is replaced in a couple weeks. We have tried putting in a claim directly to Solar Edge on a couple of occasions and got pawned off back to our installer. We installed the first shipment of Jinko/Maxim in Australia and had heaps of tv reception issues. I asked three times for corrections or additions. Cheers Peter. Communications failure since day one. Upcoming opportunities depending on green energy outlook. I installed a 5KW HD Wave Dec 2019, it failed Jan 2020 and was an approved warranty replacement. But then, maybe they start failing after 5 years. The nature of electricity is that it is not 100 per cent safe, but we can put measures in place to make it safer. I am trying to avoid the same voltage blocking issue are you have. If you google MC Electrical Enphase review you'll see my comment on Enphase. I have a new SolarEdge system that was just installed here in Canberra at the end of March and to this point, am quite happy with it. So you'll find out in 2 years. Over half of our failures have been picked up because our customer looked at the individual panel monitoring, or we have happened to stumble across it. Quite misleading. Is that a new design or an older unit? But, if you are convinced it is a SolarEdge issue and your installer is no longer around, I',m afraid you'll probably need to take it up with the ombudsman. home. Our Enphase MicroInverter failures is a grand total of 3. Amazingly I heard from SE, unfortunately excuses started flowing. The tech support then said to go on site and megger the mains cables, this makes no sense at all as a low insulation on the mains would give a low voltage not a high voltage. By the way, I like Gavin, the Australia General Manager. If youre interested in SolarEdge, we strongly recommend you get a free site design consultation as this technology needs to be used correctly to maximise your energy output. According to a site commissioning report that I ran this morning, there are 14 x P370-5RM4MRM-MM23 and 2 x P370-5RM4MRM-MM26 optimizers on the roof currently. To be honest, 1-2% efficiency isnt really enough to make that much difference but still, to get there it takes a lot of hard work, research and new technology. Hi Christine, Sorry to hear (and sorry for the delayed reply). What issues have you seen in this product used in this size installation. And the installers have lost interest and will make us wait when theres a problem even though we spent $16,000 on the system. many times it doesnt even load. You would normally only see the fully failed ops. They are really known in Australia and Europe. Hi Tom, In Australia, we can install panels to a maximum of 33 per cent over the nominal output of the inverter. This is also future ready for a battery to get included into your home system. Temperature range is -20C to +70C. If it isn't tried and tested and still alive after 5 yrs in Queensland, stay away from it is my advice and the advice pasted on to me from the solar oldies I know and respect. Andy. Hopefully, for you and the industry, SolarEdge has solved the issues with Gen 4. Am I reading that right? Then Ill be putting some good surge protection before the next wet/build up. Ive read about poly, mono, PERC, split cells, various wattages, sizes, even colours. It really is a mine field with everybody telling you that their system is the best system. Their brand represents high quality, long lasting products. As it is, the company recently boosted its planned investment in EVs to $50 billion by 2025 which is a figure that should put it well on the path to near-100% BEV production. Sometimes marketing and engineering just has the urge to create a solution - and look for a problem to fix. Their tune has now changed and they now admit they have high optimiser failure rates across the board. I believe SolarEdge are working on a S series optimiser this could be a more reliable design? I'm not volunteering to find out. For me, the energy hub really allows you to move towards a greener, more affordable future. thanks again. Technicians for Sustainability is a Tucson based, employee-owned, mission driven company specializing in renewable energy and sustainable technology for residential and commercial settings. The original MLine product, now rebranded has not changed its spots. Multiplying our 7,805 kWh of solar energy by $0.2275 gives us$1775.64. Regards from the Springbok country. Having 2 failures in 3 years is really very bad for a product with a 25-year warranty. Hi Stephen, the Jury is currently out on the Sunpower P Series. Their products have changes appreciably since your review - for the better. Winter often has the worst results. The max output that I managed to achieve (constantly reading from the inverter screen) was 4.028kW . where we detail the benefits and challenges of working with nearly any inverter on the market.. Most companies I talk to only give the customer the most basic access when they set up the SolarEdge inverter monitoring portal. Hi Zeus, I always recommend Fronius as the first option. kind regards, Christine Paton. It has, but it also has lower Isc value than for example P370. If it is shutting off 3 times a day, it's likely either because you have high grid voltage, (above 255v?) I take those obligations seriously. 7. I have watched solaredge installations on YouTube channels and was surprised at the statements made by the installer that the optimiser allows a panel to fail and the rest to of the panels increase their output.

Consider mixing it with a split cell (half cell) panel like QCell duo, or a shingle panel like SunPower p19. As to Enphase reliability - one thing we've discovered is that many "failures" are actually communications issues. It's interesting that you did work for the "important and strategic sites".
