Conceptual Diagram
The SUN2000 is a single-level inverter that converts DC power into single-phase AC power
through an inverter circuit. Surge protection is supported on both the DC and AC sides.
The SUN2000 uses a battery port to connect to batteries which are used to store the surplus
power produced by PV strings and not required by local loads. To meet peak power
consumption requirements and maximize benefits, the power stored in batteries can be
exported to the power grid based on the load condition.
