Maintenance
Regular maintenance ensures the longevity and optimal performance of your inverter:
- Cleaning: Keep the inverter clean and free from dust and debris. Use a dry cloth to wipe the exterior. Do not use liquid cleaners.
- Ventilation: Periodically check that the cooling fans and vents are clear and unobstructed.
- Connections: Inspect battery connections regularly to ensure they remain tight and free from corrosion.
- Storage: If storing the inverter for an extended period, disconnect it from the battery and store it in a cool, dry place.
The intelligent cooling fans automatically adjust speed based on load and temperature, preventing overheating and ensuring stable operation.
Troubleshooting
If you encounter issues, refer to the following table for common problems and solutions. The LCD display will show error codes (E1-E6) for specific protection indications.
| Problem / Error Code | Possible Cause | Solution |
|---|---|---|
| No Output / Inverter Off | Loose battery connections, low battery voltage, power switch off. | Check battery connections, charge battery, turn power switch ON. |
| E1: Short-circuit Protection | Short circuit in output wiring or connected appliance. | Disconnect all appliances, check wiring for shorts, reconnect one by one. |
| E2: Under-voltage Protection | Battery voltage is too low. | Recharge or replace the battery. |
| E3: Over-temperature Protection | Inverter is overheating due to poor ventilation or excessive load. | Reduce load, ensure proper ventilation, allow inverter to cool down. |
| E4: Overload Protection | Total power draw of connected appliances exceeds 3000W. | Reduce the number or wattage of connected appliances. |
| E5: Over-voltage Protection | Input voltage from battery is too high. | Check battery voltage; ensure it is within the 12V DC range. |
| E6: Pre-power Overload Protection | Indicates an overload condition detected before full power output. | Similar to E4, reduce connected load. |
