How to fix MPP Solar Inverter when it shuts down automatically during startup?
If your MPP Solar Inverter shuts down automatically during startup, it's likely due to low battery voltage. Recharge or replace the battery.
What to do if the internal relay of my MPP Solar Inverter switches on and off repeatedly?
If the internal relay of your MPP Solar Inverter switches on and off repeatedly when turned on, the battery may be disconnected. Check the battery wires to ensure they are properly connected.
Why does my MPP Solar Inverter beep continuously and the red LED is on?
A continuous beep and red LED on your MPP Solar Inverter indicates several potential issues: overload error (reduce the connected load by switching off some equipment); output short circuit (check wiring and remove abnormal load); high internal temperature (check air flow and ambient temperature); over-charged battery, abnormal output voltage, fan fault or internal component failure (return to repair center); or high battery voltage (check battery specifications).
What to do if my MPP Solar Inverter works in battery mode even when mains exist?
If your MPP Solar Inverter operates on battery despite mains being available, the input protector may be tripped (check the AC breaker and wiring). Also, the AC power quality might be insufficient (check AC wires and generator if applicable). Alternatively, change the output source priority to Utility first.
What to do if my MPP Solar Inverter doesn't respond after powering on?
If your MPP Solar Inverter shows no response after power on, it could be due to very low battery voltage (check battery connections, recharge, or replace the battery) or reversed battery polarity (recharge or replace the battery).
