8. Troubleshooting
This section addresses common issues you might encounter.
| Problem | Possible Cause | Solution |
|---|---|---|
| No power output | Inverter off; loose battery connections; low battery voltage; blown fuse | Turn on inverter; check and tighten battery cables; charge battery; inspect and replace internal fuses (professional service recommended). |
| Overload alarm/shutdown | Connected appliance wattage exceeds 2000W | Reduce the load by disconnecting some appliances. Restart the inverter. |
| Overheat alarm/shutdown | Poor ventilation; blocked cooling fans; excessive ambient temperature | Ensure clear airflow around the inverter; clean fan vents; move inverter to a cooler environment. Allow unit to cool before restarting. |
| Low voltage alarm/shutdown | Battery voltage too low | Recharge or replace the 12V battery. |
| High voltage alarm/shutdown | Input voltage too high | Verify the input voltage from the battery is within the specified range (typically 10.5V-15V for 12V systems). |
