Battery Management System (BMS)
Voltage Protection
Under Voltage Protection
while Discharging
When any battery cell’s voltage or the total voltage is lower
than the rated protection value during discharging, the
over-discharging protection will be activated, and the buzzer
will sound. The battery system will stop supplying power to the
external device. When the voltage of each cell is back to the
rated range, the protection ends.
Over Voltage Protection
while Charging
During the charging stage, the system will stop charging when
the total voltage of the battery pack is higher than the rated
value or the voltage of any single cell reaches the protection
value. When the total voltage of all cells returns to the rated
range, the protection ends.
Current Protection
Over Current Protection
while Charging
When the charge current of any module is higher than 110A,
the over-current protection mode is activated and the current
is limited to 1A. The protection will be deactivated after a rated
delay of 10s. This process will repeat until the current falls below
110A.
Over Current Protection
while Discharging
When the discharge current of any module is higher than
115A, the battery buzzer will sound, and the system will stop
discharging after 15s. When the protection ends, the discharg-
ing will restore in a 60s delay or immediately when a charging
current is present.
The buzzer sound from the alarm function can be deactivated, from the software, resulting in
the system reverting to default factory settings.

Other Protection
Short Circuit Protection
The DC circuit breaker would be triggered by a short circuit
when the battery is on. If the DC circuit breaker does not
operate, the short circuit protection function of the BMS will be
activated automatically to cut off the device’s output.
Self Shutdown When no external loads are present for over 72 hours, the
device will automatically be dormant and go on standby.
The maximum operating current required for the electrical load should be less than the
maximum discharge current capacity of the battery.
Temperature Protection
Under/Over temperature
protection while charging
When the battery’s temperature exceeds the range of 0°C ~ +
55°C during charging, the temperature protection mode will be
activated. The charging of the battery will stop. The protection
mode will be deactivated when it returns to the rated range of
working temperatures.
Under/Over temperature
protection while discharging
When the battery’s temperature exceeds the range of -20°C ~
+ 55°C during discharging, the temperature protection mode
will be activated. The battery will stop supplying power to the
external device. The protection mode will be deactivated when
it returns to the rated range of working temperatures.

Electrical Installation3
Before connecting the power cables, use a multimeter to measure the cable continuity, short-circuit
condition, and positive and negative ports. Mark them clearly on the cable labels.
Measuring method:
Power cable check
Perform visual inspection of cable connections and insulation for any damage. Perform insulation
resistance and continuity test.
Unit visual inspection
Inspect battery unit to confirm it is free from damage, confirm all electrical connections a free from
damage, debris and moisture.
After visual inspection of the power cable, the positive and negative terminals of the battery should
be connected to the respective positive and negative terminals of the inverter/charger.
1) Connect the battery box to the ground cable
Installers need to prepare M6 OT terminals and ground cables. Ground the battery shell as shown
below. The cross-section of the grounding cable should be at least 6mm², and the bolt-max torque is
6NM.
If there is any question during installation, please contact
your dealer to avoid damage to the equipment.
