- Grounding: Ensure the inverter is properly grounded according to local electrical codes.
5. Operating Instructions
- Power On: Flip the ON/OFF switch on the inverter's front panel to the "ON" position, or use the ON/OFF button on the remote controller. The LCD display will illuminate.
- Connecting Appliances: Plug your AC appliances into the US outlets or connect them to the hardwire terminal. Ensure the total continuous power consumption does not exceed 3500 Watts, and peak power does not exceed 7000 Watts.
- Monitoring with LCD Display: The LCD display provides crucial operational information:
- Battery pattern and voltage (e.g., 25.6V)
- Battery power level
- Inverter output voltage (e.g., 120V)
- Output current and frequency (e.g., 2.1A 60Hz)
- Internal temperature (e.g., 39°C)
- Protection mode indicators (flashing patterns/icons)
- Protection Mode Behavior: The inverter will automatically shut down and display an error/alarm in case of:
- Low Voltage Protection: If the input voltage drops below 20.2V (for 24V system), the inverter will alarm and shut down. (Demonstrated in Video 4.1, 0:15-0:23)
- High Voltage Protection: If the input voltage exceeds 30.4V (for 24V system), the inverter will alarm and shut down. (Demonstrated in Video 4.1, 0:23-0:28)
- Overload Protection: If the connected load exceeds 105% of the rated power, the inverter will alarm and shut down. (Demonstrated in Video 4.1, 0:29-0:34)
- Over Temperature Protection: If the internal temperature exceeds 80°C, the inverter will alarm and shut down. (Demonstrated in Video 4.1, 0:34-0:40)

7. Troubleshooting
This section addresses common issues you might encounter with your inverter. Refer to the LCD display for error indications.
| Problem | Possible Cause | Solution |
|---|---|---|
| Inverter does not turn on. | No battery connection, low battery voltage, faulty switch. | Check battery connections and voltage. Ensure battery is charged. Verify ON/OFF switch position. |
| Low Voltage Alarm/Protection (LCD shows low voltage, audible alarm). | Battery voltage is too low. | Recharge or replace the battery. Reduce load if battery is weak. |
| High Voltage Protection (LCD shows high voltage, audible alarm). | Input voltage is too high. | Check battery charging system. Ensure correct battery type (24V). |
| Overload Protection (LCD shows 105%, audible alarm). | Connected load exceeds inverter's capacity. | Disconnect some appliances to reduce the load. Restart the inverter. |
| Over Temperature Protection (LCD shows high temp, audible alarm). | Inverter is overheating due to excessive load or poor ventilation. | Reduce load. Ensure adequate ventilation around the inverter. Allow it to cool down. Clean cooling fans if obstructed. |
| No AC output. | Inverter in protection mode, faulty appliance, loose connection. | Check LCD for error codes. Test appliance with another power source. Secure all connections. |
