What to do if my SUNFLX Inverter shows bypass or inverter overload protection?
If the SUNFLX Inverter displays 'Bypass overload protection' or 'Inverter overload protection', try reducing the amount of power being used by your equipment. Then, restart the unit to resume load output.
How to troubleshoot parallel connection fault in SUNFLX SEI-8K-SP?
If the SUNFLX Inverter indicates a parallel connection fault, check the parallel line connections to ensure they are secure and correctly connected.
How to resolve battery undervoltage protection on SUNFLX SEI-8K-SP Inverter?
If the SUNFLX Inverter shows battery undervoltage protection, charge the battery until it reaches the low voltage disconnection recovery voltage.
What to do for fan failure in SUNFLX SEI-8K-SP Inverter?
If the SUNFLX Inverter displays a fan failure, check to see if the fan is spinning freely and is not obstructed by any foreign objects.
What happens when SUNFLX SEI-8K-SP's heat sink temperature is too high?
If the SUNFLX Inverter's heat sink is overheating, allow the device to cool down until the temperature falls below the recovery temperature. After that, normal charge and discharge control will resume.
How to check PV overvoltage on SUNFLX Inverter?
If the SUNFLX Inverter reports PV overvoltage, use a multimeter to check if the PV input voltage is exceeding the maximum allowable input voltage.
What to do if SUNFLX Inverter shows a battery disconnected alarm?
If the SUNFLX Inverter is alarming about a disconnected battery, verify that the battery is properly connected and that the battery circuit breaker is closed.
What to do if SUNFLX SEI-8K-SP Inverter has short-circuit protection?
If the SUNFLX Inverter indicates a short-circuit, carefully inspect the load connection and eliminate any short-circuit faults. After doing so, power the system back on to restore load output.
How to fix no display on SUNFLX Inverter screen?
If your SUNFLX Inverter screen is blank, ensure the battery or PV switch is closed and in the "ON" position. You can also try pressing any button on the screen to wake it up from sleep mode.
