3 Product Introduction

3.1 Product Naming Rules

The model involved are GW250K-HT and GW225K-HT
Model Description:
1. GW - abbreviation for GOODWE
2. 250K/225K - rated output power
3. HT - model code

3.2 Application

The HT series inverters are three-phase grid-tied PV string inverters that convert the DC power
generated by PV strings into AC power and feed the qualified power into the power grid. The
inverters are transformerless. The HT inverters can be applied in grid-tied PV systems of
large-scale or commercial and industrial PV systems. Typically, there consists of a PV string, invert-
er, transformer, and utility grid in a grid-tied PV system.
