of warranty
WARNING: Appropriate personal protective equipment (PPE) such as rubber
gloves, rubber boots and goggles should be worn when working with batteries.
Warning: System operating temperature range: 0℃～45℃, exceeding the
operating temperature range may cause the battery system temperature to be
too high/low , which will further shorten the cycle life。
For battery installation, the installer should strictly abide by the installation
operation standards.
Improper maintenance can permanently damage the battery。
Incorrect inverter parameters will further lead to battery failure/damage。
Attention!
Before installing or using the battery, it is very important and necessary to read
the user manual (included in the attachment) carefully. Failure to do so or to
follow any instructions or warnings in this document may result in electric
shock, serious injury or death, or damage to the battery, possibly rendering it
inoperable。
If the battery is stored for a long time, it is required to be charged every six
months, and the SOC should not be lower than 90%；
The battery needs to be charged within 12 hours after being fully discharged;
Do not expose cables to the outside；
1.2 In use
If the battery system needs to be moved or serviced, the power must be
disconnected and the battery turned off completely；
It is forbidden to connect the battery with a different type of battery；
Do not use the battery with a faulty or incompatible inverter；
Do not remove the battery modules；
In the event of a fire, only dry powder fire extinguishers can be used, liquid fire
extinguishers are prohibited；
1.3 Before wiring
After unpacking, please check the product and packing list first, if the product
is damaged or missing parts, please contact your local retailer;
Before installation, make sure to cut off mains power and make sure the

battery is in off mode；
The wiring must be correct, the positive and negative cables must not be
wrongly connected, and there is no short circuit with external equipment；
Do not connect the battery directly to AC power；
The battery system must be well grounded and the resistance must be less
than 4Ω；
Please ensure that the electrical parameters of the battery system are
compatible with the related equipment；
Keep batteries away from water and fire。
