8. Troubleshooting
This section provides guidance on common issues you might encounter. For more complex problems, please contact technical support.
| Problem | Possible Cause | Solution |
|---|---|---|
| Inverter does not power on. | Battery switch off, low battery voltage, loose connections. | Check battery switch, ensure battery voltage is sufficient, inspect all battery connections. |
| No AC output. | Overload, short circuit, inverter fault, PV/Mains input issue. | Reduce load, check for short circuits, refer to fault indicator (Component 4 in Figure 3.5), verify PV and mains input. |
| Fault indicator is lit. | Overcurrent, low voltage, overheating, overload. | Identify the specific fault code on the LCD display. Address the underlying issue (e.g., reduce load for overload, ensure proper ventilation for overheating). |
| Inductive loads not starting. | Starting power of load exceeds inverter capacity. | Ensure the starting power of inductive loads is within the inverter's surge capacity (typically 3x rated power). Consider a higher capacity inverter if needed. |
| WiFi monitoring not working. | WiFi module not connected, network issues, app configuration. | Verify WiFi module connection to the communication port, check local network connectivity, ensure correct app setup. |
9. User Tips
- For optimal battery life, ensure your battery type is correctly configured in the inverter settings, especially for lithium batteries (Program 05: Custom).
- Utilize the dual AC outputs to manage different load priorities. The primary circuit is switched off if battery voltage is too low, while the secondary output is maintained to save energy.
- Regularly check the RGB LCD display for system status and any alerts to ensure continuous and efficient operation.
- If using the WiFi monitoring feature, keep your mobile application updated for the best performance and access to new features.
