Battery Management System（BMS）
Voltage Protection
Discharging Low Voltage Protection：
When any battery cell voltage is lower than the protection value during discharging, the
over-discharging protection starts, and the ALM light always on. Then battery system
stops supplying power to the outside. When the voltage of each cell recovers to rated
return range, the protection is over.
Charging Over Voltage Protection：
When total voltage or any battery cell voltage reaches the protection value during
charging, battery stops charging. When total voltage and all the cell voltage recover to
rated return range, the protection is over.
Temperature Protection
Less/Over temperature protection in charging：
When battery's temperature is beyond range of 0oC~+55oC during charging, temperature
protection starts, device stops charging.The protection is over when it recovers to rated
return range.
Less/Over temperature protection in discharging：
When battery's temperature is beyond range of -20oC~+55oC during discharging,
temperature protection starts, device stops supplying power to the outside.
The protection is over when it recovers to rated return range.
Other Protection
Short Circuit Protection：
The battery does not allow external short circuit, which will damage the BMS.

Electrical installation
Before connecting the power cable and ground wire, it is recommended to use a
multimeter to measure the continuity of the cable, whether it is short-circuited, and
confirm the positive and negative.
Measuring methods:
Cable continuity: select the multimeter buzzer file, use a probe to measure both ends
of the same color cable, if the buzzer sounds, the cable is available.
Short circuit judgment: select the multimeter resistance file, use the probe to measure
the positive and negative poles of the same end, if the resistance shows infinity, it
means the cable is available.
Positive and negative poles: After the power cable is connected visually, the positive
and negative poles of the battery should be connected to the positive and negative
poles of the opposite device respectively.

4 Use, maintenance and troubleshooting
Instructions for use and operation of the battery system
After completing the electrical installation, follow the steps below to turn on the battery
system;
1. Refer to the wiring instructions of “Wiring diagram for single module use” or “Wiring
diagram for parallel use of modules", do the preparation work before the battery pack
is turned on, and then press the SW button , the RUN light is on after the self-test. SOC
indicator is on.
CAUTION
After pressing the SW button, if you find that the battery status indicator on the front
panel is continuously red, please refer to "Alarm Description" to deal with it. If the fault
cannot be eliminated, please contact the dealer in time.
2. Use a multimeter to measure whether the voltages on the DC breaker connected to
battery are more than 11.4V, and check whether the voltage polarity is consistent with
the inverter input polarity; if the DC breaker side connected to battery has output
voltage and is more than 11.4V, the battery has started working normally;
3. After confirming that the battery output voltage and polarity are correct, turn on the
inverter; Turn on the DC breaker.
4. Check whether the indicator lights (communication indicator light and battery
connection status indicator light) on the inverter are normal; if they are normal, the
connection between the battery and the inverter is completed. If the indicator is
abnormal, please refer to the inverter manual to find the reason or contact the dealer.
