- Monitor Performance: Regularly check the LCD display for any error codes or unusual readings.
- Battery Health: For lead-acid batteries, check electrolyte levels and specific gravity as per battery manufacturer guidelines.
7. Troubleshooting
If you encounter issues with your inverter, refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| No output power | Inverter off, battery low, input power issue | Check power switch, charge battery, verify AC/PV input. |
| Overload error | Connected load exceeds inverter capacity | Reduce connected load or disconnect non-essential appliances. |
| Battery not charging | PV input too low, battery connection issue, MPPT controller fault | Check solar panel output, battery wiring, and MPPT settings. |
| High temperature warning | Insufficient ventilation, blocked fan, excessive ambient temperature | Ensure clear airflow, clean fans, relocate if necessary. |
