How to fix MPP Solar LV 6548 Inverter that shuts down automatically 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). To resolve this: 1. Re-charge the battery. 2. If re-charging doesn't work, replace the battery.
What to do if MPP Solar LV 6548 has no response after power on?
If your MPP Solar Inverter is not responding after you power it on, it could be due to: * Very low battery voltage: Check the connections of the batteries and wiring. Recharge or replace the battery. * Reversed battery polarity: Check the connections of the batteries and wiring. Recharge or replace the battery.
Why does the internal relay of my MPP Solar Inverter switch on and off repeatedly?
If the internal relay of your MPP Solar Inverter switches on and off repeatedly when the unit is turned on, it indicates that the battery is disconnected. Check if the battery wires 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 beeps continuously and the red LED is on, it could be due to several reasons: * Overload error: Reduce the connected load by switching off some equipment. * Output short circuit: Check the wiring and remove any abnormal loads. * High temperature: Ensure the unit's airflow isn't blocked and the ambient temperature isn't too high. * High battery voltage: Verify the battery specifications and quantity meet the requirements. * Fan fault: Replace the fan. * Abnormal output voltage: Reduce the connected load. * Battery connection: If the battery is connected well, please return to repair center.
Why my MPP Solar Inverter works in battery mode when mains are available?
If your MPP Solar Inverter is operating in battery mode even when mains are available, it could be due to: * A tripped input protector: Check if the AC breaker is tripped and the AC wiring is properly connected. * Insufficient AC power quality: Check if the AC wires are too thin or too long, and ensure the generator is working correctly and the input voltage range setting is correct. * Incorrect output source priority: Change the output source priority to Utility first.
