6. Setup and Installation

Proper installation is crucial for the safe and efficient operation of your inverter. Please follow these steps carefully.

Choosing a Location:

• Install the inverter in a dry, well-ventilated area, away from direct sunlight, heat sources, and moisture.
• Ensure there is sufficient clearance around the inverter for airflow, especially around the cooling fans.
• Mount the inverter on a stable, non-flammable surface.

Battery Requirements:

For optimal performance and safety, use a deep cycle battery with at least 80% discharge depth. The inverter is compatible with various battery types including LI (Lithium), SLD (Sealed Lead-Acid), FLD (Flooded Lead-Acid), GEL, and AGM batteries.

The inverter supports multiple battery input types and can power various household and vehicle appliances.

Connection Steps:

1. Prepare Cables: Use the provided 7AWG positive (red) and negative (black) battery cables. Ensure the cable length is appropriate for your setup to minimize voltage drop.

7. Operation Guide

Turning On/Off:

1. Ensure all connections are secure.
2. Flip the main power switch on the inverter to the 'ON' position. The LED display will illuminate, showing input/output voltage and other parameters.
3. To turn off, flip the main power switch to the 'OFF' position.

Using the Remote Controller:

The wired remote controller allows you to turn the inverter on and off from a distance, which is convenient for installations where the inverter is not easily accessible. Simply use the switch on the remote to control the inverter's power state.

Cooling Fan Operation:

The inverter features intelligent cooling fans. These fans will automatically activate when the internal temperature reaches approximately 50 degrees Celsius or when the load reaches half of the inverter's capacity. This ensures efficient heat dissipation and maintains optimal operating temperature, contributing to the inverter's durability.

The inverter's dual cooling fans operate efficiently to maintain optimal temperature.

8. Maintenance

Regular maintenance helps ensure the longevity and reliable performance of your XWJNE inverter.

• Cleaning: Periodically clean the exterior of the inverter with a dry, soft cloth. Ensure ventilation openings and cooling fans are free from dust and debris. Do not use liquid cleaners or solvents.
• Connection Check: Regularly inspect all electrical connections (battery cables, ground wire) to ensure they remain tight and free from corrosion. Loose connections can cause overheating and damage.
• Fuse Replacement: The inverter is protected by internal fuses. If a fuse blows, the inverter may stop functioning. Replacement should only be performed by qualified personnel. Use only 40A 32V fuses as replacements.
• Storage: If storing the inverter for an extended period, ensure it is clean, dry, and stored in a cool, well-ventilated area. Disconnect it from all power sources.
