3 Product Introduction

3.1 Product Naming Rules

The models involved are as follows:
GW73KLV-HT
GW100K-HT
GW110K-HT
GW120K-HT
GW136K-HTH
Model Description (taking GW100K-HT as an example):
1. GW - abbreviation for company name
2. 100K - rated output power
3. HT - model code
3.2 Product Purpose
The HT series is a three-phase transformerless PV string grid-tie inverter, which is the key unit of
the photovoltaic system for connecting the PV string to the grid. The inverter converts the DC
power generated by the photovoltaic module into AC power that meets the parameters of the
local power grid and feeds it into the power grid. The intended use of the inverter is shown in the
diagram below:
A B
If an isolation transformer is not used on the output side of the inverter to connect to
the power grid, neither the PV+ nor the PV- input terminal of the inverter can be
connected to the ground.
