• Camping/RV Use: Light (10W), Fan (40W), Air Conditioner (1150W), Coffee Machine (550W), Projector (100W), Car Refrigerator (60W).
• Home Use: Refrigerator (15W-520W), Air Conditioner (1150W), Microwave Oven (1160W), Oven (800W), Router (15W), TV (150W).

7. Maintenance

Regular maintenance ensures optimal performance and longevity of your inverter.

• Keep Clean: Periodically clean the inverter's exterior with a dry cloth. Ensure ventilation openings are free from dust and debris.
• Check Connections: Regularly inspect battery and output connections for tightness and corrosion. Tighten as necessary.
• Storage: If storing the inverter for an extended period, disconnect it from the battery and store it in a cool, dry place.

8. Troubleshooting

The inverter features four distinct protection modes to help diagnose issues. Refer to the LCD display for error codes or indicators.

• No Output Power: Check battery connections, ensure the inverter is switched ON, and verify the battery voltage is within the operating range (10V-14V).
• Overload Protection: If the inverter shuts down due to overload, reduce the connected load and restart the inverter.
• Overheating: Ensure adequate ventilation. If the inverter overheats, it will shut down. Allow it to cool down before restarting. Dual high-efficiency cooling fans help maintain optimal temperature.
• Low/High Voltage Protection: The inverter will shut down if the input DC voltage is too low or too high to protect the battery and inverter. Check your battery's charge level or charging system.
• Short Circuit Protection: If a short circuit is detected, the inverter will shut down. Disconnect the faulty device and restart.
• Remote Control Issues: Ensure the remote control cable is securely connected. Check the remote's battery if applicable (for wireless models).
