Product code

H0/H1: product series with the 1500 V DC input voltage

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.

(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.
