5. Operating Instructions
Once the inverter is properly installed, follow these steps to operate it:
- Power On: Flip the main power switch on the inverter to the "ON" position. The LED display will illuminate.
- Monitor LED Display: The LED screen provides real-time information:
- Battery Level: Indicates the remaining charge of your connected battery.
- Input Voltage: Displays the DC voltage from the battery (e.g., 24.0V).
- Output Voltage: Shows the AC output voltage (e.g., 120V).
- Frequency: Displays the output frequency (e.g., 60Hz).
- Output Load Percent: Visualizes the percentage of the inverter's capacity currently being used.
- Inverter Normal Working: An indicator confirming the inverter is operating correctly.
- Connect Devices: Plug your 120V AC appliances into the two AC output ports or use the 5V 2.4A USB port for charging compatible devices.
- Remote Operation: Use the remote controller to turn the inverter on/off and monitor key parameters from a distance.
- Power Off: When finished, disconnect all appliances and then flip the main power switch to the "OFF" position.

6. Protection Mechanisms
The XWJNE 4000W Pure Sine Wave Power Inverter is equipped with six powerful protection functions to ensure safe and reliable operation:
- Undervoltage Protection: Automatically shuts down if the input DC voltage drops below a safe level to protect the battery from deep discharge.
- Overvoltage Protection: Protects the inverter and connected devices from damage due to excessively high input DC voltage.
- Overload Protection: Prevents damage when the connected load exceeds the inverter's rated capacity.
- Over-temperature Protection: Activates the smart cooling fan and/or shuts down the inverter if internal temperature becomes too high.
- Short Circuit Protection: Safeguards against damage from short circuits in the output.
- Reverse Connection Protection: Protects the inverter from damage if battery polarity is accidentally reversed.

7. Maintenance
Regular maintenance ensures the longevity and optimal performance of your inverter:
- Cleaning: Keep the inverter clean and free from dust and debris. Use a dry, soft cloth for cleaning. Do not use liquid cleaners.
- Ventilation: Regularly check that the cooling fans and vents are clear and unobstructed. The smart fan will automatically activate when the internal temperature reaches 50 degrees Celsius or when the load reaches half capacity, operating at low decibel levels.
- Connections: Periodically inspect all electrical connections for tightness and corrosion. Loose connections can cause overheating and damage.
- Storage: If storing the inverter for an extended period, disconnect it from the battery and store it in a cool, dry place.
