6. Setup and Installation
- Prepare the Battery: Ensure your 12V DC battery has sufficient capacity for the appliances you intend to power. Insufficient battery capacity may prevent high-power appliances from running.
- Ensure Voltage Matching: Confirm that the inverter's input voltage (12V DC) matches your battery's voltage.
- Connect Battery Cables:
- Connect the red battery cable to the positive (+) terminal of the inverter and the positive (+) terminal of your 12V battery.
- Connect the black battery cable to the negative (-) terminal of the inverter and the negative (-) terminal of your 12V battery.
- Ensure connections are tight and secure. Use the provided wrench for the inverter terminals.
- Grounding: Connect the alligator clip safety ground to the inverter's ground terminal and to a suitable ground point (e.g., vehicle chassis).
- Initial Power On: Before connecting any appliances, turn the inverter's ON/OFF switch to the "ON" position. The LCD display should illuminate, showing input voltage and other parameters.
- Connect Appliances: Once the inverter is powered on and stable, connect your AC-powered devices to the AC outlets and USB devices to the USB port. Ensure the total wattage of connected equipment does not exceed the inverter's continuous power rating (1500W).
IMPORTANT: Do not connect the inverter directly to an AC circuit breaker panel or any other AC power source. This inverter is for DC to AC conversion only.

- Always ensure the total power consumption of all connected devices does not exceed the inverter's continuous power rating (1500W). Overloading the inverter will trigger protection mechanisms.
8. Protection System
Image: Upgraded BMS System Protection Features.
The JIGUUN inverter incorporates an advanced protection system to ensure safe and reliable operation:
- Under Voltage Protection: Shuts down the inverter if the input DC voltage drops too low (10.0±0.5V DC) to protect the battery from over-discharge.
- Over Voltage Protection: Shuts down the inverter if the input DC voltage exceeds a safe level (15.0±0.5V DC).
- Overload Protection: Automatically shuts down if the connected load exceeds the inverter's capacity.
- Over Temperature Protection: Activates cooling fans when the internal temperature exceeds 45°C and shuts down if it becomes too high.
- Short Circuit Protection: Protects against short circuits in the output.
- AC Ground Terminal: Provides a safety ground connection.
- Reverse Connection Protection: Protects the inverter and battery from damage due to incorrect polarity connection.
If any protection is triggered, the inverter will typically shut down. Disconnect the load, resolve the issue, and then restart the inverter.
9. Maintenance
- Cleaning: Periodically clean the exterior of the inverter with a dry, soft cloth. Ensure cooling vents are free from dust and debris. Do not use liquid cleaners.
- Connections: Regularly check all DC input connections to ensure they are tight and free from corrosion. Loose connections can cause overheating.
- Storage: When not in use for extended periods, store the inverter in a cool, dry place away from direct sunlight and moisture. Disconnect it from the battery.
- Battery Maintenance: Ensure your 12V battery is properly maintained and charged according to its manufacturer's instructions. A healthy battery is crucial for optimal inverter performance.
10. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Inverter does not turn on. | No power from battery; loose connections; low battery voltage. | Check battery connections and voltage. Ensure battery is charged. |
| No AC output. | Overload; short circuit; over-temperature; low/high input voltage. | Reduce load. Check for short circuits. Allow inverter to cool. Check battery voltage. |
| Fans are constantly running or very loud. | High internal temperature due to heavy load or poor ventilation. | Ensure adequate ventilation. Reduce load. Clean vents if blocked. |
| Connected appliance not working correctly. | Appliance power requirement exceeds inverter capacity; appliance not compatible with pure sine wave. | Check appliance wattage. Ensure appliance is suitable for pure sine wave power. |
