5. Operation
5.1 Powering On/Off
- After ensuring all connections are secure, switch the inverter's power button to the "ON" position.
- The LCD display will illuminate, showing operational parameters.
- To turn off, switch the power button to the "OFF" position.
5.2 Understanding the LCD Display
The integrated LCD provides real-time feedback on the inverter's status:
- Input Voltage (V): Displays the DC voltage from the battery.
- Output Voltage (V): Shows the AC output voltage (e.g., 220V).
- Frequency (Hz): Indicates the AC output frequency (e.g., 50Hz or 60Hz, depending on model).
- Load Power (W): Displays the current power consumption of connected devices.
- Temperature (°C): Shows the internal operating temperature of the inverter.

5.3 Connecting AC and USB Devices
Once the inverter is powered on, you can connect your devices:
- Plug AC appliances into the 220V AC outlets. Ensure the total wattage does not exceed 5000W.
- Connect USB-powered devices to the USB charging port.
6. Maintenance
Regular maintenance helps prolong the life of your inverter.
- Cleaning: Periodically clean the exterior of the inverter with a dry, soft cloth. Ensure ventilation openings are free from dust and debris. Do not use liquid cleaners.
- Connection Check: Regularly inspect all electrical connections (battery terminals, inverter cables) 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.
7. Troubleshooting
The inverter is equipped with multiple protection features that may cause it to shut down or display an error. Refer to the LCD display for specific indicators.
| Problem | Possible Cause | Solution |
|---|---|---|
| Inverter not turning on | Loose battery connections, low battery voltage, faulty fuse. | Check battery connections, charge battery, check inverter fuses. |
| Overload Protection (Inverter shuts down) | Total power draw of connected devices exceeds 5000W. | Reduce the load by disconnecting some appliances. Restart the inverter. |
| Overheating Protection (High temperature on LCD) | Poor ventilation, blocked fans, excessive ambient temperature. | Ensure adequate ventilation, clear fan vents, allow inverter to cool down. |
| Low Voltage Protection | Battery voltage is too low (below 24V threshold). | Recharge or replace the battery. |
| High Voltage Protection | Battery voltage is too high (above 24V threshold). | Check battery charging system. Disconnect inverter until voltage stabilizes. |
| Short Circuit Protection | Short circuit in connected appliance or wiring. | Disconnect all appliances and check for faults. Restart inverter. |
