What to do if AC utility power fails and the opti-solar Inverter load is supplied by battery power with a buzzer alarm every 4 seconds?
If AC power fails and your opti-solar Inverter is running on battery with the alarm sounding every 4 seconds, it could be due to an AC power failure or an incorrect AC input connection. Try reducing the less critical load to extend backup time and check the rated input or connected line.
What happens if AC utility fails and the opti-solar SP is in battery backup mode with a buzzer alarm beeping every second?
If the opti-solar Inverter is in battery backup mode and the buzzer beeps every second, it means the battery power is approaching a low level. The Inverter will shut down automatically soon, so save your data or turn off loads quickly.
What to do if the opti-solar SP Inverter is overloaded when AC utility power is normal?
If the opti-solar Inverter is overloaded (load between 100% and 125%) while AC power is normal, the warning LED will light up and the buzzer will beep once per second. Reduce the critical load to below 100% to resolve this.
What to do if the opti-solar SP warning LED does not fade out and the buzzer beeps per 0.5 second when AC utility power is normal?
If the warning LED doesn't fade and the buzzer beeps every 0.5 seconds on your opti-solar Inverter, it means the load is between 125% and 150%. Please reduce the critical load to below 100%.
What should I do if the opti-solar SP Inverter warning LED lights up and the buzzer beeps continuously when AC utility power is normal?
If the warning LED is on and the buzzer beeps continuously while AC power is normal, the load on your opti-solar Inverter exceeds 150%. Reduce the critical load to below 100%.
How to fix the fault LED and continuous beeping on my opti-solar SP Inverter when AC power is normal?
If the fault LED lights up and the buzzer beeps continuously on your opti-solar Inverter while AC power is normal, the cause might be a damaged charger PCB, a damaged fan, or an unknown error. You can try replacing the charger PCB or the fan. Alternatively, try restarting the Inverter.
What happens if AC utility power fails and the opti-solar Inverter shuts down automatically?
If the opti-solar Inverter shuts down automatically after AC power fails, it's likely because the battery ran out. The Inverter will restart when AC power is restored.
