- Monitor the LCD display for any fault codes or unusual readings.
7. Troubleshooting
If you encounter issues with your inverter, refer to the following common troubleshooting steps. For persistent problems, contact customer support.
7.1. Common Issues and Solutions
| Problem | Possible Cause | Solution |
|---|---|---|
| Inverter not turning on | No battery connection, low battery voltage, power switch off, faulty wiring. | Check battery connections and voltage. Ensure power switch is ON. Verify all wiring is correct and secure. |
| Fault indicator lit | Overload, short circuit, high/low battery voltage, high temperature, PV input issue. | Reduce load. Check for short circuits. Verify battery voltage is within range. Ensure adequate ventilation. Check PV input connections and voltage. |
| No AC output | Overload, inverter fault, AC output wiring issue. | Reduce connected load. Check AC output wiring. If fault persists, contact support. |
| Battery not charging | No PV input, low PV voltage, AC input issue, incorrect battery settings. | Check solar panel connections and sunlight. Verify AC input is present. Adjust battery type settings on LCD. |
Note: The inverter is designed to be compatible with a variety of daily appliances. However, it is crucial to avoid overloading the unit. Refer to the load selection model below for guidance.
