1. Introduction
Thank you for choosing the Xijia 2000W Pure Sine Wave Inverter. This device converts 72V DC battery power into 120V AC household power, enabling you to operate various electronic devices and appliances from your vehicle, RV, boat, or off-grid solar system. This manual provides essential information for safe installation, operation, and maintenance of your inverter.
A pure sine wave inverter produces AC power that is identical to, or even better than, the power supplied by your utility company. This makes it suitable for sensitive electronics, medical equipment (like CPAP machines), and appliances with motors, ensuring their longevity and efficient operation.
2. Important Safety Instructions
Please read and understand all safety instructions before installing or operating the inverter. Failure to follow these instructions may result in electric shock, fire, serious injury, or property damage.

4. Setup and Installation
4.1 Choosing a Location
- Install the inverter in a cool, dry, and well-ventilated area.
- Avoid direct sunlight, heat sources, and moisture.
- Mount the inverter securely on a stable surface.
- Ensure there is at least 6 inches (15 cm) of clear space around the inverter for proper airflow.
4.2 Connecting to the DC Power Source (Battery)
Important: Ensure the inverter's power switch is in the OFF position before making any connections.
Image: Inverter Dimensions and Battery Cables. This image illustrates the physical dimensions of the inverter and the recommended battery cable connections, showing red for positive and black for negative terminals.
- Identify the positive (+) and negative (-) terminals on your 72V DC battery bank.
- Connect the red battery cable to the positive (+) terminal of the inverter and then to the positive (+) terminal of the battery.
- Connect the black battery cable to the negative (-) terminal of the inverter and then to the negative (-) terminal of the battery.
- Ensure all connections are tight and secure to prevent loose connections, which can cause overheating and damage.
- Use appropriate gauge cables for your power requirements. The provided cables are 4AWG for 12V/24V and 7AWG for 48V, but for 72V, ensure your cables are rated for the current.
4.3 Connecting the Remote Control
Plug the remote control cable into the designated RJ45 port on the inverter. The remote control allows you to turn the inverter ON/OFF from a convenient location.
5. Operating Instructions
5.1 Turning the Inverter ON/OFF
- To Turn ON: Ensure all DC connections are secure. Flip the main power switch on the inverter (or the remote control switch) to the 'ON' position. The 'Inverter ON' indicator light will illuminate, and the LCD display will show operational parameters.
- To Turn OFF: Disconnect all AC loads from the inverter. Flip the main power switch on the inverter (or the remote control switch) to the 'OFF' position.
5.2 Connecting AC Loads
- Plug your 120V AC appliances directly into the AC outlets on the inverter's front panel.
- Ensure the total continuous wattage of all connected appliances does not exceed 2000W. For appliances with high startup (surge) power, ensure the combined surge power does not exceed 4000W.
- The pure sine wave output is suitable for sensitive electronics such as laptops, TVs, CPAP machines, and power tools.
