The SUN2000 is a three-phase grid-tied PV string inverter that converts the DC power generated by PV strings into AC power and feeds the power to the power grid.
The SUN2000 applies to grid-tied PV systems for commercial rooftops and large plants. Typically, a PV system consists of the PV strings, SUN2000, AC power distribution unit (PDU), and low-voltage power grid.
