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 S C 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 the battery, include any internal or external components.
Do not connect battery with PV solar wiring directly.
Any foreign 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 D N T 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
