Why does my Sun Gold Power Inverter beep continuously and the red LED is on?
- J
  Julia JohnsonAug 7, 2025
  The continuous beeping and red LED on your Sun Gold Power Inverter could be due to several reasons: * **Overload:** Reduce the load by switching off some equipment. * **Short Circuit:** Check the wiring and remove any abnormal load. * **Over Temperature:** Ensure the inverter's airflow isn't blocked and the ambient temperature isn't too high. * **Other Issues:** In some cases, it may indicate over-charged battery, fan fault, output abnormality, internal component failure, over current or surge, poorly connected battery or burnt fuse, requiring you to return the unit to a repair center. Also, check if the spec and quantity of batteries meet requirements.

Why is my Sun Gold Power Inverter working in battery mode when mains exist?
- K
  Katelyn TaylorAug 13, 2025
  If your Sun Gold Power Inverter is operating in battery mode even when mains are available, it could be due to a tripped input protector. Check if the AC breaker has tripped or if the AC wiring is properly connected. It could also be due to insufficient quality of AC power. Check if the AC wires are too thin or too long, and if a generator is being used, ensure it's working correctly and that the input voltage range setting is correct. Alternatively, change the output source priority to Utility first.

How to fix Sun Gold Power Inverter that shuts down automatically during startup?
- A
  Amy ArcherAug 19, 2025
  If your Sun Gold Power Inverter shuts down automatically during startup, it's likely because the battery voltage is too low (less than 1.91V/Cell). You should try to recharge the battery. If the problem persists, consider replacing the battery.

What to do if Sun Gold Power Inverter has no response after power on?
- D
  Deborah JohnsonAug 26, 2025
  If your Sun Gold Power Inverter isn't responding after you power it on, the battery voltage might be too low (less than 1.4V/Cell). First, check that the batteries and wiring are properly connected. Then, try recharging the battery. If it still doesn't work, you may need to replace the battery.
