![]() ![]() This would prevent solar contributing to your house fire, and the firefighters will appreciate that you used a solar solution that enables rapid shutdown. If the SolarEdge inverter is turned off, the optimised panels will produce a safe 1 volt each. SolarEdge’s optimisers require communication with the inverter in order for them to operate. Optimizers and microinverters offer a solution that brings another level of safety. The nature of electricity is that it is not 100 per cent safe, but we can put measures in place to make it safer. If solar systems are installed by electricians who follow today’s standards, your solar is arguably as safe as the rest of the electrical wiring in your home. I deliberately didn’t call this section “enhanced safety” or “SafeDC” as SolarEdge brand it, because that infers other solar systems are not safe. So if one panel is shaded, it does not drag down the performance of the next. It takes the MPPT’s out of the inverter and effectively puts one MPPT (or optimiser) behind every panel. The SolarEdge Inverter offers one solution to this problem. The potential problem with standard string inverters is that a string of panels works kind of like old school Christmas tree lights: if one panel is affected by shade, then all the panels in the string are affected. As the sun’s intensity changes throughout the day, the two MPPT’s will continually adjust the voltage and the current from the panels to achieve maximum power. The panels on a house are divided into two groups (or strings) and connected to the two MPPT’s in the inverter. ![]() Standard string inverters have two MPPT’s. To step back a bit, let’s look at one of the key components of any solar inverter: the Maximum Power Point Tracker (or MPPT). So what are they doing right? Optimisation Today they are second only to SMA for the number of residential inverters they are moving, and the way I read it, they have been successful are making money hand over fist. They only kicked off in 2006 with the first inverter sales in 2010. Compared to their competitors, they are the new kids on the block. SolarEdge is a huge player in today’s solar inverter market. Some of the requested changes were inaccurate and the agreement would not allow for future updated to this blog so I didn’t agree. SolarEdge Lawers asked for more changes in July 2020 so that they would not persue claims. I’ve updated this blog to removed some, arguably cheap-shots and irrelevant arguments in order to negotiate a truce. Then on the day before Good Friday 2019, I received further threats from SolarEdge. Instead, I amended Part Three to address their concerns, and I added lots of bonus updates. The letter demanded I remove Part Three of this post. On Christmas Eve of 2018 at 3:15 pm, I received a letter from SolarEdge lawyers. Failure rates were last updated in December 2020. Part three is where I address the five significant problems I have discovered with SolarEdge: failure rates, monitoring, alerts, underperformance and blocking. In part two, I pull apart SolarEdge’s newest model, the SolarEdge HD Wave. In part one, I explain the SolarEdge inverter theoretical advantages. Part one and two are a condensed version of my original review. Since then SolarEdge lawyers have sent me threats on two occasions about this blog. But, as time went on, significant problems started appearing so I changed this SolarEdge review to voice my concerns with SolarEdge. We installed over 3000 SolarEdge optimisers, and I had a tour of the SolarEdge HQ in Israel and had meetings with some of SolarEdge’s founders. It’s been a couple of years since I first wrote this SolarEdge inverter review. ![]()
