Using this, underperforming panels can also be highlighted and assessed for issues. MLPE’s offer a range of benefits including power optimisation to ensure every panel is performing at its peak power output, plus panel-level monitoring to provide real-time power generation data from every panel in a solar array. Power optimisers, along with micro-inverters are generally known in the industry as MLPE or Module Level Power Electronics, which as the name suggests consists of electronic power conversion units attached directly to individual solar panels. SolarEdge DC Power Optimisers are small add-on electronic devices that enable each solar panel to operate at its maximum power point. I should also mention power optimisers cannot generate additional power during bad weather or when most of the panels are dirty, or shaded, sorry they aren’t magic! For example, if multiple panels are shaded or underperforming the optimisers can only compensate so much (as they have a limited range) before whole system performance is reduced. Of course, there are some limitations to the SolarEdge system. SolarEdge optimisers are in effect DC to DC converters that work together to deliver the optimum string voltage to the inverter for maximum power. If several panels are shaded or underperforming resulting in low voltage or current, the other panel optimisers can compensate (up to a point) for the poor-performing panels and provide the optimum string voltage for maximum performance. The power optimisers work much like a maximum power point tracker (MPPT) and can either boost or reduce the panel voltage to deliver the optimum voltage to the inverter. They work by using DC power optimisers connected to each solar panel. SolarEdge Inverters on the other hand operate at very specific voltage point (typically 380V). This generally works very well unless there is partial shading, dirty cells or issues with one or more panels which often results in the whole string power being reduced. String inverters track the voltage and convert the DC power to AC at the maximum power point (MPP) of the entire string. Depending on the weather conditions and time of day this results in a wide range of string operating voltages. ![]() Conventional solar inverters convert DC power from a string of solar panels connected in series to AC power. Despite the disadvantages such as higher upfront cost and added complexity, there are several advantages to using DC optimised systems as we explain in detail below.īefore we explain how the SolarEdge systems works, we will quickly describe how a common string solar system works. ![]() SolarEdge systems have long held a large market share in the US and popularity has increased in Australia, while European sales have also grown as both customers and installers discover the benefits of panel-level monitoring to help reduce the impact of shading. Founded in 2006, SolarEdge is rather unique among Inverter suppliers as they do not manufacture conventional string solar inverters but what the company refers to as ‘intelligent inverter systems’ using power optimisers to maximise power generation at the individual panel level. SolarEdge Technologies headquarters based in Israel supplies a wide range of inverters for residential, commercial and small utility-scale solar installations, along with a range of optimisers and smart energy solutions. ![]() ![]() Home > solar inverters > best inverters review > SolarEdge Inverter Review
