1.Try to lower the ambient temperature.
2.Make sure that the inverter is installed
according to the manual and there is no
shelter around the inverter.
3.After the inverter is powered off and

Battery
over-voltage
protection
The voltage exceeds
equalized charge and
floating charge 20v
Check whether the actual battery voltage
exceeds the battery charging cut-off voltage
by more than 20v.
Battery
under-voltage
protection
Voltage lower than
battery cut-off
voltage.
Check whether the actual battery voltage is
lower than the battery discharge cut-off
voltage.
Battery Voltage less than Confirm that the wiring is normal, and
