1Safety Instructions
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 onsite 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 your distributor first. If the problem persists, con-
tact SUNGROW in time.

2
1.2 Installation Safety
Make sure there is no electrical connection before installation.
Before drilling, avoid the water and electricity wiring in the wall.
Improper installation may cause personal injury!
• If the product supports hoisting transport and is hoisted by hoisting tools, no
one is allowed to stay under the product.
• When moving the product, be aware of the product weight and keep the balance
to prevent it from tilting or falling.
Before operating the product, must check and ensure that tools to be used have
been maintained regularly.
1.3 Electrical Connection Safety
Before electrical connections, please make sure that the inverter is not damaged,
otherwise it may cause danger!
Before electrical connections, please make sure that the inverter switch and all
switches connected to the inverter are set to "OFF", otherwise electric shock may
occur!
The PV string will generate lethal high voltage when exposed to sunlight.
• Operators must wear proper personal protective equipment during electrical
connections.
• Must ensure that cables are voltage-free with a measuring instrument before
touching DC cables.
• Respect all safety instructions listed in relevant documents about PV strings.
1 Safety Instructions User Manual

Danger to life due to a high voltage inside the inverter!
• Be sure to use special insulation tools during cable connections.
• Note and observe the warning labels on the product, and perform operations
strictly following the safety instructions.
• Respect all safety instructions listed in this manual and other pertinent
documents.
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.

1.4 Operation Safety
Please comply with the following requirements when the product is running:
• Do not touch its enclosure.
• It is strictly forbidden to plug and unplug any connector on the inverter.
• Do not touch any wiring terminal of the inverter. Otherwise, electric shock may
occur.
• Do not disassemble any parts of the inverter. Otherwise, electric shock may
occur.
• It is strictly forbidden to touch any hot parts of the inverter (such as the heat
sink). Otherwise, it may cause burns.
• Do not operate the DC switch if the inverter is equipped with the DC switch. Oth-
erwise, device damage or personal injury may occur.
1.5 Maintenance Safety
Risk of inverter damage or personal injury due to incorrect service!
• Before any service work, first disconnect the grid-side AC circuit breaker and
check the inverter status. If the inverter indicator is off, please wait until night to
disconnect the DC switch. If the inverter indicator is on, directly disconnect the
DC switch.
• After the inverter is powered off for 10 minutes, measure the voltage and cur-
rent with professional instrument. Only when there is no voltage nor current
can operators who wear protective equipment operate and maintain the inverter.
• Even if the inverter is shut down, it may still be hot and cause burns. Wear pro-
tective gloves before operating the inverter after it cools down.
Touching the power grid or the contact points and terminals on the inverter con-
nected to the power grid may lead to electric shock!
• The power grid side may generate voltage. Always use a standard voltmeter to
ensure that there is no voltage before touching.
To prevent misuse or accidents caused by unrelated personnel, post prominent
warning signs or demarcate safety warning areas around the product.

To avoid the risk of electric shock, do not perform any other maintenance opera-
tions beyond those described in this manual. If necessary, contact your distributor
first. If the problem persists, contact SUNGROW. Otherwise, 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 product in accordance with relevant local regulations and stand-
ards to avoid property losses or casualties.

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.
