Inverters are just one example of a class of devices called power electronics that regulate the flow of electrical power. Fundamentally, an inverter accomplishes the DC-to-AC conversion by switching the direction of a DC input back and forth very rapidly. As a result, a DC input. . To improve grid stability, many electric utilities are introducing advanced grid limitations, requiring control of the active and reactive power of the inverter by various mechanisms. SolarEdge inverters with CPU version 2. 337 and later support these requirements (some features may require later. . In this post, we'll look at four reactive power control modes that can be selected in modern smart inverters to control inverter reactive power production (or absorption) and subsequently voltage where the plant connects to the system.
