Network Application
The inverter applies to grid-tied PV systems for commercial rooftop PV plants and large PV plants. Typically, a grid-tied PV system consists of the PV string, inverter, AC power distribution unit, and step-up transformer.
(A) PV string
(B) Inverter
(C) AC distribution unit (ACDU)
(D) Step – up transformer
(E) Power grid
Note: The SUN2000 is powered by a dedicated power transformer instead of connecting to low voltage overhead power lines.
Supported Power Grid
The inverter supports the IT power grid.
