1 Safety Messages and Precautions
1.1 Declaration
Please read this manual carefully before installation, operation, and maintenance. Inappropriate
use may lead to injury or even death for the user or third parties. Material damage to the battery
and other equipment can also occur. All operations should be performed by a qualified person.
The manufacturer will not be liable for any consequences of the following circumstances:
• Operation beyond the conditions specified in this document.
• The installation and use environment do not comply with relevant international or national
and regional standards.
• Failure to follow the operation instructions and safety messages on the batteries and in this
document.
• Product damage caused by an unstoppable natural disaster.
• Damage caused during transportation by the customer.
• Damage caused by storage conditions that do not meet the requirements specified in
related documents.
• Damage caused by the device due to negligence, improper operation, or intentional
damage to the device.

~ 7 ~
1.2 General Safety Requirements
DANGER
• Ensure the housing of the battery packs is properly grounded before operation.
• Do not dispose of batteries in a fire or hash chemicals. The batteries may explode.
• The disassembly of batteries may generate internal short circuits, which may cause
firing or other problems.
• Do not open or mutilate batteries. Released electrolyte is harmful to the skin and
eyes. It may be toxic.
• Batteries theoretically do not have flowing electrolytes
, but in the event of any
leakage and contact with skin, eyes, or other parts of the body, flush the electrolyte
with water immediately and seek medical attention.
•
The battery may be damaged due to impact or other reasons during transportation
or assembly. If the battery is found to have any abnormal characteristics, such as
the housing being damaged, the electrolyte gas, the electrolyte leak, etc. The battery
shall not be used. Contact the dealer or installer to replace it.
• Do not expose the cable externally which may cause a short-circuit to the battery
or electric shock to humans.
• Do not touch the output terminals of the battery pack while it is working. The DC
cables connected to an inverter may be live. Touching live DC cables may result in
death or serious injury due to electric shock.
• When performing high-voltage operations, use dedicated insulation tools.

~ 8 ~
WARNING
• Wear suitable personal protective equipment for all work on the battery system.
•
Before installation, be sure to cut off the power grid and ensure that the battery is
in shutdown mode.
• For the equipment that
needs to be grounded, install the protective earthing (PE)
cable first when installing the equipment and remove the PE cable last when
removing the equipment. Do not operate the equipment in the absence of a properly
installed grounded conductor.
• Remove metal objects from your body while operating, such as watches, necklaces,
and rings.
• Connect all cables according to the instructions and ensure no reverse connection
for positive and negative poles. No external short circuit.
• Do not connect the battery to the utility grid or AC source directly.
• Do not mix and match this battery with other batteries.
• If a fire occurs ABC, or carbon dioxide extinguisher can be used.
NOTICE
• Inspect the package contents upon receipt. Notify the dealer if there is any damage.
•
Do not operate this battery pack in direct sunlight, in contact with fluids, or where
there is excessive dust or high humidity.
• Do not lay tools or metal parts on top of the battery.
• Do not place inflammable items around the equipment.
•
Wear ESD gloves when handling the equipment. Do not wear clothes prone to static
electricity.
• The battery modules cannot be stored at high temperatures (greater than 60 °C)
•
The battery system must only be used as stationary equipment. If the battery system
needs to be moved or repaired, the power must be cut off and the battery has to be
completely shut down.

or irreversible damage to the batteries.
2) The battery is damaged, falls, or leaks due to improper operations or incorrect
connection.
3) Battery parameters are incorrectly set.
4) After being installed and connected to the system, the batteries are not powered on
in time, which causes damage to the batteries due to over-discharge.
5) The batteries are overloaded or used with other batteries, including but not limited
to batteries of other brands or batteries of different rated capacities.
6) The batteries are damaged because the operation is outside the recommended
environment or external power parameters do not meet the stated technical
specifications.
7) Batteries are frequently deep-discharged or have not been fully charged for a long
time.
8) The warranty period of batteries has expired.

2 Product Introduction
2.1 Overview
The Lithium-Ion Battery Pack System is a high-power DC battery system for use with inverters.
It contains two parts, one is the battery module, and the other is the control box.
It can store and release electric energy based on the requirements of the inverter. It has a built-in
intelligent battery management system (BMS), which can manage and monitor the battery voltage,
temperature, current and other information. The battery pack system can be used individually or
in parallel, and the capacity and power can be expanded according to different requirements.
2.2 Battery Capacity Description
The battery supports power and capacity expansion. One power control box supports a maximum
of five battery expansion modules. The capacity of each module is 3.8 kWh.
Figure 1 Modules in series for power and capacity expansion

~ 11 ~
Figure 2 Battery in parallel for capacity expansion
Note: Two batteries in parallel only support capacity expansion, power expansion is not suggested.
The Module quantity of each string of battery should be the same.
2.3 Battery application on the Grid
The battery can be used in the grid-tied systems of residential rooftop PV plants.
