What to do if PowMr Inverter shows no display on the screen?
If there's no display on the screen of your PowMr Inverter, first ensure that the battery air switch or the PV air switch is closed and in the "ON" state. If the switch is on, try pressing any button on the screen to wake it from sleep mode.
What to do if PowMr Inverter has bypass overload protection or inverter overload protection?
If your PowMr Inverter is showing 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.
What to do if PowMr POW-LVM3K-24V-H Inverter has short circuit protection?
If your PowMr Inverter is experiencing short circuit protection, carefully inspect the load connection and fix any short-circuit issues. After clearing the fault, power the unit back on to restore load output.
What to do if my PowMr POW-LVM3K-24V-H Inverter reports a battery missed alarm?
If your PowMr Inverter is reporting a battery missed alarm, check to ensure the battery is properly connected and that the battery circuit breaker is closed.
What to do if PowMr Inverter fan fails?
If the fan on your PowMr Inverter fails, check if the fan is not turning or if it's obstructed by a foreign object.
What to do if Inverted AC Output Backfills to Bypass AC Input on PowMr POW-LVM3K-24V-H Inverter?
To address inverted AC output backfilling to bypass AC input on your PowMr Inverter, disconnect the AC, PV, and battery inputs. Once the screen is off, reconnect only the battery and start the system. If fault 26 appears, the AC input relay switch may be short-circuited, and you should contact the manufacturer for a replacement.
