1.Safety Precautions
It is very important and necessary to read the user manual carefully before installing or using the
battery. Failure to follow any of the instructions or warnings in this document can result in
electrical shock, serious injury, death, or may damage the battery and the whole system.
If the battery is stored for a prolonged time, it is requirement that they are charged every three to
six months, and the SOC should be no less than 80%.
The battery needs to be recharged within 12 hours, after fully discharging.
Do not expose cable outside.
All battery terminals must be disconnected before maintenance.
Do not use cleaning solvents to clean the battery.
Do not expose the battery to flammable or harsh chemicals or vapors.
Do not paint any part of battery, include any internal or external components.
Do not connect battery with PV solar wiring directly.
Any other extra object is prohibited to be inserted into any part of the battery.
Any warranty claims are excluded for direct or indirect damage due to items above.
1.1.Before Connecting
After unpacking, please check the battery and packing list first, if the battery is damaged or spare
parts are missing, please contact the dealer.
Before installation, be sure to cut off the grid power and make sure the battery is in the turned-off
mode;
Wiring must be correct, do not mix-connect the positive and negative cables, and ensure no short
circuit with the external device;
It is prohibited to connect the battery with AC power directly;
The embedded BMS in the battery is designed for 48VDC, please DO NOT connect battery
in series;
It is prohibited to connect the battery with different type of battery;
Please ensure the electrical parameters of battery system are compatible to inverter;
Keep the battery away from fire or water.
1.2.During operation
If the battery system needs to be moved or repaired, the power must be cut off first and the
battery is completely shutdown;
It is prohibited to connect the battery with different type of battery;
It is prohibited to put the batteries working with faulty or incompatible inverter;
In case of fire, only dry powder fire extinguisher can be used, liquid fire extinguishers are
prohibited;
Please do not open, repair or disassemble the battery. We do not undertake any consequences
or related responsibility due to violation of safety operation or violating of design, production and
equipment safety standards.
