Important Safety Notification

General

This user manual contains important instructions and notifications that must

be followed during installation and maintenance of the CPS grid-tied PV

Inverter.

The CPS grid-tied PV Inverter is a well-designed product through strict tests

to meet international safety requirements, but as an electrical and electronic

equipment, certain precautions must be observed during the installation and

operation of the PV Inverter.

In order to avoid personal injury during installation and daily operation of the

Inverter, users must read and follow all instructions, cautions and warnings

that are described in this manual.

Electrical Code

CPS grid-tied PV Inverters follow the National Electrical Code and other local

regulations to meet the requirements of electrical installation in the United

States. For the electrical installation in Canada, inverter installation must be

completed in accordance with applicable Canadian standards.

Safety Instructions

This manual contains important safety instructions to minimize the hazards to

people and equipment. Not following the procedures and practices correctly

could result in damage to or destruction of part or all of the CPS grid-tied PV

Inverter and/or other equipment connected to the Inverter or personal injury.

Preventive Regulation of Product

The Inverter should be installed, operated and maintained by qualified

personnel who have read and understood the operation instructions. The

qualification of the personnel is defined in the National Electrical Code.

Moreover, CPS grid-tied PV Inverters are provided with fixed trip limits and

shall not be aggregated above 30kW on a single point of common

connections.

Safety Symbols

ELECTRIC SHOCK

Electric shock indicates a potential risk of electric shock if not

avoided.

WARNING

Warning indicates a potentially hazardous situation that could

result in death or serious injury if not avoided.

CAUTION

Caution indicates a hazardous situation that could result in minor

injury if not avoided.

HOT SURFACE

Hot surface indicates a hot surface during operation that could

result in a burn injury if not avoided.

IMPORTANT

Important indicates important and useful information that the user

should know about the system.

ESD Protection

Risk of electric shock can occur when qualified service personnel

are dealing with the electrical components within the PV Inverter,

such as wiring box. An ESD glove should be worn during the

wiring operation, fuse replacement and component installation.

Tool Equipment Symbols

Multi-Meter

Multi-meter symbol indicates that a multi-meter is needed for

measuring to ensure the proper operational functionality of

components.

Tools

Tools symbol indicates that specific tools are required during

installation procedures.

1. Introduction

This manual describes all the information needed to install and operate the

following PV Inverter Models:

CPS SCE4KTL-O/US, CPS SCE5KTL-O/US, CPS SCE6KTL-O/US, and

CPS SCE7KTL-O/US

IMPORTANT

In order to avoid problems during the installation, it is

recommended to read the entire user manual before any

installation procedures.

Any improper usage may result in damage to the unit. Therefore, it is

important that all installation procedures shall be completed by qualified

personnel that have been trained to install and operate PV Inverters.

Moreover, this user manual only describes the information that is needed for

the CPS grid-tied PV Inverter and does not cover any installation information

relating to other equipment installed in the PV system. The following safety

instruction should be followed:

WARNING

It is necessary that only qualified personnel conduct the

installation and operation of the PV Inverter. Otherwise, risk of

damage to or destruction of part or all of the Inverter and/or other

equipment connected to the Inverter or personal injury due to

improper installation procedures or practices.

ELECTRIC SHOCK

Alternating Current (AC) and Direct Current (DC) sources are

directly connected to the terminals in the PV Inverter. In order to

prevent risk of electric shock before maintenance or installation, it

is necessary to ensure that all AC and DC terminals are

disconnected.

HOT SURFACE

Although the inverter is designed to meet international safety

standards, the surface of the inverter can become hot during

operation. Therefore, do not touch the heat sink or peripheral

surfaces during or shortly after operation.

ELECTRIC SHOCK

Risk of electric shock from energy stored in capacitors. Do not

remove the cover until three minutes after disconnecting all

sources of power supply and the service should be done by

qualified personnel.

2. Limited Warranty

The warranty policy of this product is specified in the contract; otherwise,

the warranty period is 10 years.

The Inverter has been used for purposes other than for which it was

designed

The Inverter has been used beyond its stated specifications, operating

parameters and application

Acts of third parties, atmospheric discharges, excess voltage,

chemical influences, natural wear and tear and for loss and damage

in transit

Improper testing, operation, maintenance, adjustment, repair, or any

modification of any kind not authorized in writing by the inverter

4. Product Overview

4.1 Introduction of Grid-tied PV system

The grid-tied PV system is mainly composed of four parts: PV modules, DC

distribution unit, grid-tied PV inverter and AC distribution unit. When the PV

modules are exposed to sufficient irradiation, they will generate DC power.

First, the DC will be fed to the PV Inverter (via DC distribution unit). Then the

Inverter converts the DC to AC and feeds AC to the Public Grid via the AC

distribution unit. The AC power can be used directly by the local load, or it can

be sold to your energy supplier.

The following figure shows the general picture of a grid-tied PV System:
