Why is my opti-solar Inverter working in battery mode when mains exist?
- L
  Lori RomeroAug 11, 2025
  If your opti-solar Inverter continues to operate in battery mode even when mains power is available, the issue could stem from a few causes. First, the input protector might be tripped; check if the AC breaker is tripped and ensure the AC wiring is securely connected. Alternatively, the quality of the AC power from the shore or generator could be insufficient; verify that the AC wires aren't too thin or excessively long. If you're using a generator, confirm it's functioning correctly and that the input voltage range setting is correct (specifically for UPS Appliance models). Also, consider changing the output source priority to Utility first.

What to do if opti-solar SP6000 Handy Ultra Inverter has no response after power on?
- D
  Dale SmithAug 17, 2025
  If your opti-solar Inverter doesn't respond after you power it on, there are a couple of things to check. First, the battery voltage may be far too low (below 1.4V/Cell). Second, the battery polarity may be connected reversed. Ensure that the batteries and wiring are connected correctly and securely. If the connections are good, try recharging the battery. If recharging doesn't work, consider replacing the battery.

  If your opti-solar Inverter shuts down automatically during the startup process, it's likely due to low battery voltage (less than 1.91V/Cell). Try recharging the battery. If the issue persists, consider replacing the battery.

What causes the internal relay to switch on and off repeatedly on opti-solar SP6000 Handy Ultra?
- T
  Thomas SweeneyAug 29, 2025
  If the internal relay of your opti-solar 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 well.

What to do if opti-solar Inverter buzzer beeps continuously and red LED is on?
- P
  Philip WolfNov 5, 2025
  A continuous beep and a red LED on your opti-solar Inverter indicate several potential issues. It could be due to an overload error (inverter is overloaded beyond 110%), a short circuit in the output, or the temperature of an internal component being too high (over 120°C). It might also indicate that the battery is over-charged or that the battery voltage is too high. A fan fault, abnormal output voltage (below 190Vac or above 260Vac), internal component failure, over current or surge, unbalanced output voltage, bus voltage being too low, or poor battery connection/blown fuse could also be the cause. Here's what you can do: * Reduce the connected load by switching off some equipment. * Check the wiring and remove any abnormal loads. * Ensure the unit's airflow isn't blocked and the ...
