1Safety

When installing, commissioning, operating, and maintaining the product, strictly observe the

labels on the product and the safety requirements in the manual. Incorrect operation or work

may cause:

• Injury or death to the operator or a third party;

• Damage to the product and other properties.

• The safety instructions in this manual are only supplements and cannot cover

all the precautions that should be followed. Perform operations considering ac-

tual on-site conditions.

• SUNGROW shall not be held liable for any damage caused by violation of gen-

eral safety operation requirements, general safety standards, or any safety in-

struction in this manual.

• When installing, operating, and maintaining the product, comply with local laws

and regulations. The safety precautions in this manual are only supplements

to local laws and regulations.

1.1 Unpacking and Inspection

Check all safety signs, warning labels and nameplates on devices.

Ensure that the safety signs, warning labels and nameplates must be clearly visible

and cannot be removed or covered before the device is decommissioned.

After receiving the product, check whether the appearance and structural parts of

the device are damaged, and check whether the packing list is consistent with the

actual ordered product. If there are problems with the above inspection items, do

not install the device and contact SUNGROW in time.

1.2 Installation Safety

Make sure there is no electrical connection before installation.

Before drilling, avoid the water and electricity wiring in the wall.

Batteries deliver electric power, resulting in burns or a fire hazard when they are

short circuited, or wrongly installed.

Lethal voltages are present at the battery terminals and cables connecting to the

inverter. Severe injuries or death may occur if the cables and terminals in the inver-

ter are touched.

Damage to the product caused by incorrect wiring is not covered by the warranty.

• Electrical connection must be performed by professionals.

• All cables used in the PV generation system must be firmly attached, properly

insulated, and adequately dimensioned.

Check the positive and negative polarity of the PV strings, and connect the PV con-

nectors to corresponding terminals only after ensuring polarity correctness.

During the installation and operation of the inverter, please ensure that the positive

or negative poles of PV strings do not short-circuit to the ground. Otherwise, an

AC or DC short-circuit may occur, resulting in equipment damage. The damage

caused by this is not covered by the warranty.

Comply with the safety instructions related to PV strings and the regulations re-

lated to the local grid.

User Manual 1 Safety

To avoid the risk of electric shock, do not perform any other maintenance opera-

tions beyond this manual. If necessary, contact SUNGROW for maintenance. Oth-

erwise, the losses caused is not covered by the warranty.

Improper settings or maintenance can permanently damage the battery.

Incorrect inverter parameters will lead to the premature aging of battery.

1.6 Disposal Safety

Please scrap the inverter in accordance with relevant local regulations and stand-

ards to avoid property losses or casualties.

User Manual 1 Safety

2Product Description

2.1 System Introduction

• The inverter must only be operated with PV strings with class II protection in ac-

cordance with IEC 61730, application class A. It is not allowed for the positive

pole or the negative pole of the PV strings to be grounded. This can cause the

inverter to be destroyed.

• Do not connect any local load between the inverter and the AC circuit breaker.

For the TT utility grid, the N line voltage to ground must be 30 V or less.

The inverter applies only to the scenarios described in this manual.

The three-phase hybrid inverters are applicable to both on-grid and off-grid PV systems.

With the integrated Energy Management System (EMS), they can control and optimize the

energy flow so as to increase the self-consumption of the system.

2.2 Product Introduction

Model Description

The model description is as follows (take SH10RTas an example):

Appearance

The image shown here is for reference only. The actual product received may differ.

Symbol Explanation

Danger to life due to high voltages!

Only qualified personnel can open and service the inverter.

Do not touch live parts for 10 minutes after disconnection from

the power sources.

Additional grounding point.

2.4 LED Indicator

The LED indicator on the front of the inverter indicates the working state of the inverter.

table 2-1 LED indicator description

LED indicator LED state Definition

Blue

ON The inverter is running in the on/off-grid mode.

Twinkling The inverter is at standby or startup state

(without on/off-grid operation).

Red

ON A system fault has occurred.

Gray

OFF Both the AC and DC sides are powered down.

Voltage may still be present in AC side circuits after the indicator is off. Pay atten-

tion to the electricity safety during operating.

2.5 DC Switch

The DC switch is used to safely disconnect the DC circuit whenever necessary.
