Maintenance
Fault
Solutions
Make sure the battery is properly connected and charged to
be able to recognize the solar inverter.
or click any button on the screen to exit screen sleep mode.
Screen not displaying
Measure whether the battery voltage exceeds 60Vand
disconnect the photovoltaic array from and the power-on.
Rechargeable battery
overvoltage protection
Wait until the battery is charged to return to above the low
voltage recovery voltage.
Battery undervoltage
protection
Disconnect or reduce any loads from the unit. Shut down the
solar inverter charger and turn on again to clear the error.
Inverter short-circuit
protection
Check with the meter if the PV input voltage is above the
maximum allowable input voltage of 145 V operating voltage.
PV overvoltage
Check that the battery is not connected or that the battery
side circuit breaker is not closed.
Battery missed alert
When the temperature of the equipment cools to, normal
charge and discharge control is restored.
Over-temperature Protection
(1) Reduce the use of electrical equipment;(2) restart the
solar inverter charger and load recovery output.
Overload Protection
Check that the fan is not turning or is blocked by something else.Fan failure
In order to maintain optimal long-term performance, it is recommended to perform inspections
of the following items twice a year.
1. Make sure that the air flow around the solar inverter is not blocked and remove any dirt or
debris from the radiator.
2. Check all terminals to see if there is corrosion, insulation damage, high temperature or
combustion / discoloration signs, tighten the terminal screws.
Danger of electric shock! Make sure that all power supplies on solar inverter disconnected and
that all capacitive power is released before checking or operating accordingly!
