3 Product Overview
3.1 Product Introduction
The inverters are single-phase gird-connected PV string inverters without transformer, which can convert the DC power
from the photovoltaic (PV) strings into alternating current (AC) power, and feed the power into the power grid.
This document involves the following product models:
CSI-3K-S22002-E, CSI-5K-S22002-E, CSI-5K-S22003-E.
PV grid-connected system mainly includes PV modules, DC switch, inverter, AC switch, electricity meter, and local grid.
The PV power system diagram is shown as FIG.3-1.
