    Why does my opti-solar Inverter work in battery mode when mains exist?
    • M
      Mary PayneAug 8, 2025
      If your opti-solar Inverter continues to operate in battery mode even when mains power is available, it could be due to a tripped input protector. In this case, verify that the AC breaker hasn't tripped and that the AC wiring is securely connected. Another cause could be insufficient AC power quality, especially when using shore power or a generator. To resolve this, check if the AC wires are adequately sized and not excessively long. If using a generator, ensure it is functioning correctly and that the input voltage range setting is correct for your UPS appliance.

      If your opti-solar Inverter isn't responding after you power it on, the battery voltage might be too low. In this case, try to recharge the battery. Another possible cause is a tripped internal fuse. If this is the case, contact a repair center to replace the fuse.

    Why does my opti-solar Inverter shut down during startup?

      Christopher HillAug 28, 2025
      If your opti-solar Inverter shuts down automatically during the startup process, it's likely that the battery voltage is too low (less than 1.91V/Cell). To address this, first, try to recharge the battery. If the issue persists, consider replacing the battery.
