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.

4 Storage
The following requirements should be met when the inverters need to be stored:
Do not unpack the inverter.
Storage temperature: –40°C ~ +70°C.
Storage humidity: 0% ~ 100%RH (Non-Condensing).
The warehouse should be clean, well-ventilated, and non-corrosive gas, meanwhile it should be accessible all the time.
No smoking, no illegal use of electricity and fire.
When storing inverters, do not stack more than the allowed layers to avoid damage, which number marked on the
product packaging.
Regular inspection is required during the storage.
After long periods storage, the inverters need to be inspected and tested by technicians persons before they are put
into use.
5 Unpackaging and Inspection
Before unpacking the inverter, check the package appearance thoroughly, such as for holes and cracks, and check the
inverter model accordingly. If you discover any damage to the packaging which indicates the inverter may have been
damaged, or the inverter model is not the one you requested, do not unpack the product and contact your dealer
immediately.
