Why is my PNI GreenHouse SC1800B Inverter working in battery mode when mains exist?
- M
  Michelle CampbellAug 10, 2025
  If your PNI Inverter works in battery mode even when mains are available, it could be due to these reasons: * The input protector is tripped. Check if the AC breaker is tripped or if the AC wiring is connected correctly. * The AC power quality is insufficient (from shore or generator). Check if the AC wires are too thin or too long. Also, if using a generator, ensure it's working correctly and that the input voltage range setting is correct.

How to fix a PNI Inverter that shuts down during startup?
- L
  Lisa CarrollAug 16, 2025
  If the PNI Inverter shuts down automatically during startup, it's likely because the battery voltage is too low (less than 1.91V/Cell). To resolve this, try recharging the battery. If that doesn't work, the battery may need to be replaced.

What to do if my PNI GreenHouse SC1800B Inverter has no response after power on?
- R
  Rebecca FloresAug 22, 2025
  If your PNI Inverter doesn't respond after you power it on, the battery voltage might be too low (less than 1.4V/Cell). First, check if the battery wires are connected properly. If they are, try recharging the battery. If it still doesn't work, you may need to replace the battery.

Why does the relay switch on and off repeatedly on my PNI Inverter?

  Brian CortezAug 28, 2025
  If the internal relay of the PNI Inverter switches on and off repeatedly when you turn it on, it's likely that the battery is disconnected. Check if the battery wires are connected correctly.
