Why is my opti-solar Inverter working in battery mode when mains are available?

  Todd OchoaAug 12, 2025
  If your inverter is operating in battery mode despite mains being available, the issue might stem from a tripped input protector. Check whether the AC breaker has tripped or if the AC wiring is properly connected. Another potential cause could be insufficient AC power quality, particularly from shore power or a generator. In this case, verify that the AC wires aren't too thin or long. If using a generator, confirm it's functioning correctly and that the input voltage range setting is correct. You can also try changing the output source priority to “USB” (utility first).

  If your opti-solar Inverter doesn't respond after powering on, the battery voltage might be too low, so try recharging the battery or replacing it. Also, the internal fuse might have tripped; in this case, contact a repair center to replace the fuse.

  Brandon MurphyAug 25, 2025
  If your opti-solar Inverter shuts down automatically during startup, it's likely because the battery voltage is too low (less than 1.91V/Cell). Try recharging the battery. If the problem persists, you may need to replace the battery.

What to do if the opti-solar Inverter buzzer beeps continuously and the red LED is on?
- K
  Kevin HarrisNov 5, 2025
  If the buzzer is beeping continuously and the red LED is on, it could be due to several reasons: * The inverter might be overloaded. Try reducing the connected load by switching off some equipment. * If the PV input voltage is too high, it may cause overload. Reduce the number of PV modules or the connected load. * There might be a short circuit in the output. Check the wiring and remove any abnormal loads. * The internal converter component might be overheating. Ensure the unit's airflow isn't blocked and the ambient temperature isn't too high. * The battery voltage may be too high. Check if the specifications and quantity of batteries meet the requirements. * The fan may be faulty. Replace the fan. * The output may be abnormal (Inverter voltage below than 190Vac or is high...
