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 |
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.
The SUN2000 can also apply to the AC power system with the neutral point grounding of the step-up transformer. The SUN2000 itself does not connect to any neutral wire.
