SolarEdge develops and markets solar inverters, monitoring software, battery storage and related products for residential, commercial and industrial PV systems. Founded in 2006, it was the first company to commercialise the power optimizer, which tracks the maximum power point at module level before sending energy to a central inverter.
In many PV systems, panels are wired in series to a central inverter, so output is limited by the weakest panel and affected by shading and weather. SolarEdge solves this with a small power optimizer behind each panel that performs module-level MPPT and enables panel-level monitoring instead of string-level data.
