APPLICATION
Small-sized Industrial and Residential Use
Our 20kW, 25kW, and 30kW 3 phase solar inverter with dual MPPTs are designed for small-sized industrial and residential solar systems. These inverters efficiently convert DC power from solar panels into AC power and feature dual MPPT technology, optimizing energy production by managing multiple panel arrays with different orientations or shading conditions. With reliable grid synchronization, these inverters offer high efficiency and ensure stable power supply for both residential and small industrial setups.
