What to do if MPP Solar LV 3KVA-24V Inverter has no response after power on?
If your MPP Solar Inverter isn't responding after you power it on, it could be due to very low battery voltage (less than 1.4V/Cell) or reversed battery polarity. To resolve this: * Ensure the batteries and wiring are properly connected. * Attempt to recharge the battery. * Consider replacing the battery if necessary.
Why does my MPP Solar LV 3KVA-24V Inverter shut down during startup?
If your MPP Solar Inverter shuts down automatically during the startup process, it's likely because the battery voltage is too low (less than 1.91V/Cell). Try recharging the battery or replacing it.
How to fix MPP Solar LV 3KVA-24V Inverter internal relay switching on and off repeatedly?
If the internal relay of your MPP Solar Inverter switches on and off repeatedly when you turn it on, the battery might be disconnected. Check the battery wires to ensure they are properly connected.
What to do if my MPP Solar Inverter buzzer beeps continuously and the red LED is on?
If your MPP Solar Inverter's buzzer is beeping and the red LED is illuminated, it indicates a few potential issues. It could be due to an overload (reduce the connected load by switching off some equipment), a short circuit (check wiring and remove abnormal loads), the internal converter being too hot (check airflow and ambient temperature), a fan fault (replace the fan), or the battery voltage being too high (check battery specifications). In some cases, the unit may need to be returned to a repair center, especially if internal components have failed, there's an overcurrent or surge (try restarting first), or the battery connection is faulty (if reconnecting doesn't work, return for repair).
Why is my MPP Solar Inverter working in battery mode when mains exist?
If your MPP Solar Inverter continues to operate in battery mode even when mains power is available, the issue might stem from a tripped input protector (check the AC breaker and wiring). It could also be due to poor AC power quality from the shore or generator (inspect AC wires and generator functionality, ensuring the input voltage range is correctly set). Alternatively, try changing the output source priority to 'Utility first'.
