5. Setup
5.1 Location and Mounting
Choose a dry, well-ventilated area for installation. Ensure there is sufficient space around the inverter for airflow, especially near the cooling fans. Mount the inverter securely on a flat, stable surface.
5.2 DC Input Connection
- Ensure the inverter is turned OFF.
- Connect the red battery cable to the positive (+) terminal of your 12V battery.
- Connect the other end of the red cable to the positive (+) DC input terminal on the inverter.
- Connect the black battery cable to the negative (-) terminal of your 12V battery.
- Connect the other end of the black cable to the negative (-) DC input terminal on the inverter.
- Ensure all connections are tight and secure.
5.3 Grounding
Connect a grounding wire from the inverter's grounding terminal to a proper earth ground point (e.g., vehicle chassis, ground rod).
5.4 Remote Control Connection
Plug the 6-meter remote control cable into the 'Remote Connect' port on the inverter and the corresponding port on the remote control panel.

6. Operating Instructions
6.1 Powering On/Off
- After ensuring all connections are correct, press the main power switch on the inverter or the remote control panel to turn the unit ON.
- The LCD display will illuminate, showing input voltage, output voltage, and current power.
- To turn OFF, press the power switch again.
6.2 Connecting AC Devices
Plug your AC appliances into the 110V-120V AC outlets on the inverter. Ensure the total wattage of connected devices does not exceed the inverter's continuous power rating (3000W).
6.3 Using USB Ports
Connect your USB-compatible devices to the USB-A (5V 2.1A) or USB-C (18W) ports for charging.
