3 Product Overview

3.1 Product Introduction

The inverters are single-phase grid-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-7K-S22002-E; CSI-8K-S22002-E; CSI-9K-S22002-E.

PV grid-connected system mainly includes PV modules, DC switch, inverter, AC switch, electricity meter, and local grid.

3.3 Product Nameplate

The nameplate provides a unique identification of the inverter (Product type, device -specific characteristics,

certificates and approvals).

The nameplate is on the left side of the enclosure.

FIG.3-3 Inverter Nameplate (for reference)

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 noncorrosive 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 technical Engineer before they are put

into use.

5 Unpackaging and Inspection

5 Unpackaging and Inspection

Before unpacking the inverter, check the package appearance thoroughly, such as any holes and cracks, and check the

inverter model accordingly. If discover any damage to the packaging which indicates the inverter may have been

damaged, or the inverter model is not what you requested, do not unpack the product and contact your dealer

immediately.

After opening the package, check all of the accessories carefully in the carton. If any damage is found or any

component is missing, contact your dealer.

Notice:

1) For component details, see the packing list document in the packing case.

2) Need two persons to carry the inverter.

6 Installation

6.1 Basic Installation Requirements

1) Do not install the inverter on the structures constructed of flammable, thermolabile or explosive materials.

2) The installation surface must be strong enough to bear the inverter's weight for a long period time. (Please check

the inverter’s weight in the product specification of Appendix B).

3) The inverter is protected to IP65, can be installed indoors and outdoors.

4) The humidity of the installation location should be below 100% without condensation.

5) The ambient temperature should be between -25°C to 60°C.

6) Install at eye-level for easy operation.

7) Do not install the inverter near television antenna or any other antennas and antenna cables.

8) Ensure the inverter is out of children's reach.

9) Install inverter at the locations with some cover or protection, to ensure the optimum operation, as per FIG.6-1.

10) Do not install in small closed cabinet where air cannot circulate freely. Do not put any other objects on the inverter,

as per FIG.6-2.

FIG.6-1 Inverter Installation Positions FIG.6-2 Forbid to Install in Small Closed Cabinet

11) Comply with the Min. clearance to walls, other inverters, or objects to ensure the installation and maintenance,

meanwhile for the good heat dissipation.

12) Install the inverter vertically or at a maximum backward tilted angle of 15 degrees to facilitate heat dissipation,

and to ensure that no moisture can penetrate the product.

0~15°

FIG.6-5 Installation Angle Requirements

13) Do not install the inverter outdoors in salt, sulfur or other corrosive areas.

The inverter would be corroded in salt area (i.e. marine environments), and the corrosion may cause fire. Salt area

refers to the region within 500 meters from the coast.

Please consult the CSI Solar Co., Ltd. technical support department on the use of inverters in special climates (i.e. salt,

sulfur, or ammonia areas) which may affect the product warranty.

14) Need two persons to install the inverter.

2) Drill expansion anchors into the corresponding four holes, and then secure the bracket by using screws, as per FIG.

6-7 & FIG. 6-8.

FIG.6-7 Install Expansion Anchors FIG.6-8 Fix Wall-mounting Bracket

6.3 Installing Inverter

Note: It must be ensured that the wall-mounting bracket was accurately mounted fixed to the wall before installing

the inverter.

Procedure:

1) Hang the inverter on wall-mounting bracket. Keep balance during the operation to prevent device damage from

colliding with walls or obstacles, as per FIG. 6-9.

2) Use two safety bolts to fix both sides of inverter to ensure the inverter fixed to the wall firmly, as per FIG. 6-10.
