2 Product Introduction

2.1 Intended Usage

The inverter is a transformerless three-phase PV grid-connected inverter, is an integral component in the PV power
system.
This document involves the following product models:
CSI-75K-T40001-E, CSI-100K-T4001A-E, CSI-100K-T4001B-E, CSI-110K-T4001A-E, CSI-110K-T4001B-E, CSI-120K-T4001A-E
and CSI-120K-T4001B-E.
The inverter is designed to convert the direct current power generated from the PV modules into grid-compatible AC
current and feeds the AC current to the utility grid. The intended usage of the inverter is illustrated in figure as bellow,
inverter application in PV power system.
A
A) PV string; B) Inverter; C) AC distribution box/cabinet; D) Transformer station; E) Utility grid
Inverter cannot connect the PV strings whose positive and negative terminals need to be grounded.
Do not connect any local load between the inverter and the AC circuit breaker.
