5. Setup Instructions
Proper setup is crucial for the safe and effective operation of your inverter.
5.1 Choosing a Location
- Place the inverter on a flat, stable surface.
- Ensure adequate ventilation around the inverter. Do not place it in an enclosed space or block the fan vents.
- Keep the inverter away from direct sunlight, heat, moisture, and flammable materials.
5.2 Grounding the Inverter
For safety, the inverter must be properly grounded.
- Locate the grounding terminal on the inverter (refer to Figure 1).
- Connect a grounding wire (not included) from the grounding terminal to a proper earth ground point. In a vehicle, this can be the chassis. In an RV or off-grid system, connect to the system's main grounding point.
5.3 Connecting to a 12V DC Power Source
The inverter offers two connection methods depending on the power requirements of your devices.

Method 1: Cigarette Lighter Plug (for loads under 150W)
- Ensure the inverter's power switch is in the 'OFF' position.
- Insert the cigarette lighter plug cable into the inverter's DC input port.
- Plug the other end of the cigarette lighter cable into your vehicle's 12V cigarette lighter socket.
- This method is suitable for low-power devices such as laptops, routers, cameras, and air pumps, provided their combined wattage does not exceed 150W.
Method 2: Battery Cables (for loads between 150W and 500W)
- Ensure the inverter's power switch is in the 'OFF' position.
- Connect the red battery cable to the inverter's positive (+) terminal and the black battery cable to the inverter's negative (-) terminal. Ensure connections are tight.
- Connect the other end of the red battery cable to the positive (+) terminal of your 12V battery.
- Connect the other end of the black battery cable to the negative (-) terminal of your 12V battery.
- Double-check all connections for polarity and tightness. Incorrect polarity can damage the inverter and battery.
6. Operating Instructions
6.1 Powering On the Inverter
- After ensuring all connections are secure and correct, switch the inverter's power switch to the 'ON' position.
- The LCD display will illuminate, showing various operational parameters.
- The smart cooling fan may activate briefly during startup or when a load is applied.
6.2 Understanding the LCD Display
The intelligent LCD display provides real-time information about the inverter's status.

- Input Voltage (VDC): Displays the current DC voltage from your battery.
- Output Voltage (VAC): Shows the AC output voltage (typically 110V/120V).
- Battery Level: Indicates the approximate charge level of the connected battery.
- Output Frequency (Hz): Displays the AC output frequency (typically 60Hz).
- Output Power (W): Shows the current wattage being drawn by connected AC devices.
- Protection Indication: Icons or messages may appear to indicate active protection modes (e.g., overload, low voltage).
- Fan Status: Indicates if the cooling fan is active.
6.3 Connecting AC and USB Devices
- With the inverter powered on, plug your AC appliances into the 120V AC sockets.
- Plug your USB-powered devices into the USB or Type-C ports for charging.
- Monitor the output power on the LCD display to ensure you do not exceed the inverter's 500W continuous rating.
- For optimal performance and to prevent battery drain, turn off the inverter when not in use.
7. Maintenance
Regular maintenance helps ensure the longevity and reliable operation of your inverter.
