Function

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.

Networking Application

The SUN2000 applies to grid-tied PV systems for commercial rooftops and large PV plants. Typically, a grid-tied PV system consists of the PV string, SUN2000, alternating current distribution unit (ACDU), and isolation transformer.

In medium-voltage grid connection scenarios and non-low-voltage public grid connection scenarios (industrial environment), the SUN2000 is powered by a dedicated power transformer instead of connecting to low-voltage overhead power lines.

Supported Power Grid

The SUN2000-50KTL-M0 and SUN2000-60KTL-M0 support the following power grid modes: TN-S, TN-C, TN-C-S, TT, and IT. The SUN2000-65KTL-M0 supports only IT grid mode.
