2. Safety Information
Always observe the following safety precautions to prevent injury or damage to the inverter and connected devices:
- Ensure proper ventilation around the inverter. Do not block cooling vents.
- Keep the inverter away from water, moisture, and flammable materials.
- Connect the inverter only to a 12V DC power source. Connecting to a different voltage may cause damage.
- Always connect the ground cable before connecting battery cables.
- Observe correct polarity when connecting battery cables (Red to positive, Black to negative). Reverse polarity protection is built-in, but incorrect connection should be avoided.
- Do not open the inverter casing. There are no user-serviceable parts inside.
- Disconnect the inverter from the power source before performing any maintenance or cleaning.
- The inverter features 8 advanced safety protections: short circuit, input over/under-voltage, overload, over-temperature, reverse polarity, high input voltage, and low output voltage protection.

4. Setup Instructions
4.1 Connecting the Inverter to a Battery
- Ensure the inverter is turned OFF.
- Connect the included ground cable to the inverter's ground terminal and then to a suitable ground point (e.g., vehicle chassis or earth ground).
- Connect the RED battery cable to the positive (+) terminal of the inverter and then to the positive (+) terminal of your 12V battery.
- Connect the BLACK battery cable to the negative (-) terminal of the inverter and then to the negative (-) terminal of your 12V battery.
- Ensure all connections are tight and secure to prevent arcing and ensure efficient power transfer.
4.2 Connecting the Remote Control
The 15ft remote controller provides convenient operation. Plug the remote control cable into the designated port on the inverter. The remote allows you to turn the inverter on/off and monitor battery status from a distance.
4.3 Adjustable Input Voltage for Lithium Batteries
This inverter features an upgraded adjustable input voltage setting, specifically designed for compatibility with lithium batteries. Refer to the detailed instructions in the full product manual for custom voltage settings to optimize performance and extend battery lifespan. This feature helps reduce battery draw and prevents premature shutdown.

5. Operating Instructions
5.1 Powering On/Off
Once connected, press the power button on the inverter or the remote control to turn the unit ON. The LCD display will illuminate, indicating operational status. Press the button again to turn OFF.
5.2 Using the LCD Display
The LCD screen provides real-time data:
- Battery Status: Visual indicator of battery charge level.
- Input Voltage: Displays the DC voltage from your battery.
- Output Voltage: Shows the AC output voltage (110V/120V).
- Load Watts: Indicates the current power consumption of connected devices.
- Protection Codes: Displays specific codes if a protection feature is activated (e.g., overload, low voltage).
The screen features an automatic rest function, dimming after one minute of inactivity to save energy and prolong screen life.

5.3 Connecting Appliances
The inverter provides multiple output options:
- 3 AC Outlets: For standard 110V/120V AC devices.
- 1 PD36W USB-C Port: For fast charging compatible devices.
- 1 3.6A USB-A Port: For charging various USB-powered devices.
Connect your devices to the appropriate outlets. Ensure the total continuous power draw of all connected devices does not exceed 1500W. For devices with high startup current (e.g., motors, compressors), ensure their surge power requirement is within the inverter's 3100W peak capacity.
