How to fix MPP Solar Inverter that shuts down automatically during startup?
If your MPP Solar Inverter shuts down automatically during the startup process, it may be because the battery voltage is too low (less than 1.91V/Cell). Try recharging the battery. If that doesn't work, consider replacing the battery.
What to do if MPP Solar Inverter has no response after power on?
If your MPP Solar Inverter doesn't respond after powering it on, it could be due to a very low battery voltage (less than 1.4V/Cell). Check the batteries and wiring to ensure they are well connected. Another possibility is reversed battery polarity, in this case, re-charge battery. If the issue persists, the battery may need to be replaced.
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 turned on, check if the battery wires are properly connected, as the issue might be due to a disconnected battery.
Why is my MPP Solar Inverter working in battery mode when mains are available?
If your MPP Solar Inverter is running in battery mode even when mains are available, it could be due to a tripped input protector. Check if the AC breaker has tripped and ensure the AC wiring is properly connected. It may also be caused by insufficient AC power quality, so check if the AC wires are too thin or too long. Also check if generator (if applied) is working well or if input voltage range setting is correct. Finally, try changing the output source priority to Utility first.
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 indicate several issues. It might be due to an overload (above 110%), in which case, reduce the load by switching off some equipment. Check for a short circuit in the output and ensure the wiring is properly connected, removing any unusual loads. For 1-3KVA models, verify that the unit's airflow isn't blocked and the ambient temperature isn't too high. Other potential causes include over-charged battery (in this case return to repair center), high battery voltage (check if the battery specifications and quantity meet the requirements), fan fault (replace the fan), abnormal output voltage (reduce the connected load), internal components failure (return to repair center), over current or surge (restart the unit, an...
