is correct. (UPS appliance) change output
source
Check to make sure battery wires are
properly connected.
Check whether the environment around the
equipment is well ventilated.

Check to make sure battery specifications
and quantities meet requirements.
Return to repair center.
Reduce solar panels.
Check whether the battery temperature is too
high, the BTS cable to the battery is loose,
and open the cover to check whether the BTS
cable to the control board is loose.
Reduce the connected load by switching off
some equipment.
Check to make sure wiring is connected
properly and remove abnormal load.
Check whether the environment around the
equipment is well ventilated.
Check to make sure battery specifications
and quantities meet requirements.
Replace the fan.
Check the input voltage of the solar panel.
1. Improve the use environment.
2. Check the temperature sensor for damage.
3. Return to the maintenance center.
