setting
1. Reduce or disconnect the load. If the alarm
is released, the battery voltage returns to
normal, indicating that the load power is too
large or the battery voltage and capacity are
low. It is easy to cause undervoltage
protection with heavy load;
2. Disconnect the load controller and still
alarm, the battery voltage does not return to
the over-discharge recovery setting value, and
the battery pack needs to be charged by PV or
other means, so that the fault can be released
after the battery pack voltage reaches the
recovery point set value.

1. The ambient
temperature is too high,
the heat dissipation of
the equipment is poor,
and the fan is not well
ventilated; 2. The fan is
damaged.
1. Check the installation environment of the
equipment, remove the debris of the
equipment, and ensure that the fan is
ventilated smoothly; 2. The fan needs to be
replaced if it is damaged.

Load power is too large
1. Reduce the load power;
2. Restart and release the fault;
3. Without excessive sensibility and capacitive
load;
Remark: The above fault phenomenon can not be turned on except the battery under voltage, other
faults can refer to the fault information through the PC background or mobile APP;
