What to do if my MPP Solar Inverter shows an overload fault?
If your MPP Solar Inverter shows an overload fault, first remove some of the connected devices to reduce the load. Ensure that the total power consumption of your connected devices is less than the inverter's maximum power capacity. Then, restart the inverter.
Why does the MPP Solar Inverter leakage current exceeds the allowable range?
If the leakage current exceeds the allowable range on your MPP Solar Inverter, it may be due to high ground voltage. First, disconnect the AC breaker, then the DC breaker. After the LCD screen shuts down completely, check if the grounding is properly connected. If the grounding is correctly connected, turn on the DC breaker. When the LCD screen displays “No Utility”, turn on the AC breaker. The system should automatically connect to the grid after 300 seconds. If the error persists, further assistance may be needed.
What to do if MPP Solar Inverter shows over temperature fault?
If your MPP Solar Inverter is showing an over temperature fault, it means the internal temperature is too high. Allow the inverter to cool down to room temperature. If the error message continues to appear, further assistance may be needed.
What to do if MPP Solar Inverter output is short circuited?
If there's a short circuit on the output of your MPP Solar Inverter, turn off the inverter. Then, disconnect the AC circuit breaker, followed by the DC circuit breaker, and then disconnect the loads. Check the load circuit to ensure it is working correctly. After resolving the short circuit, turn on the PV DC breaker and battery breaker. Finally, turn the inverter back on. If the error persists, further assistance may be needed.
What to do if MPP Solar Inverter says battery disconnected?
If your MPP Solar Inverter indicates that the battery is disconnected, check if the battery cable is firmly connected. If the error message remains after checking the connection, further assistance may be needed.
What to do if DC bus voltage exceeds the upper threshold on MPP Solar Inverter?
If the DC bus voltage exceeds the upper threshold on your MPP Solar Inverter, first disconnect the AC circuit breaker, then disconnect the DC circuit breaker. Wait until the LCD screen completely shuts down, then turn on the DC breaker first. The LCD screen should display “No Utility”. Then, turn on the AC breaker. The system will automatically connect to the grid after 300 seconds. If the error message continues, further assistance may be needed.
What to do if auxiliary power failed on MPP Solar Inverter?
If the auxiliary power fails on your MPP Solar Inverter, turn off the inverter and then restart it. If the error message persists, further assistance may be needed.
What to do if MPP Solar Inverter shows fan fault?
If your MPP Solar Inverter is showing a fan fault, first check if the fans are running correctly. If the fans are running, shut down the inverter and then restart it. If the fans are not running or if the error message persists after restarting, further assistance may be needed.
How to fix reverse connection of input and output wires on MPP Solar Inverter?
If the input and output wires are reversed on your MPP Solar Inverter, shut down the inverter completely. Check if the grid wires are connected to the AC output terminals. If they are mis-connected, reconnect them correctly and turn the inverter on again. If the error message persists, further assistance may be needed.
What to do if MPP Solar Inverter shows OP Current Sensor fault?
If your MPP Solar Inverter is showing an OP Current Sensor fault, shut down the inverter completely and then restart it to see if the issue is resolved. If the error message persists, further assistance may be needed.
