- The fans operate quietly and activate only when the internal temperature reaches approximately 45°C or when the load capacity exceeds 2800W.
- This smart cooling mechanism helps extend the inverter's lifespan and ensures stable performance.
5. Setup & Installation
5.1 Connecting to a 12V Battery
Follow these steps to safely connect your inverter to a 12V DC power source:
- Ensure the inverter's power switch is in the 'OFF' position.
- Connect the red battery cable to the positive (+) terminal of your 12V battery.
- Connect the other end of the red cable to the positive (red) terminal on the inverter. Tighten securely.
- Connect the black battery cable to the negative (-) terminal of your 12V battery.
- Connect the other end of the black cable to the negative (black) terminal on the inverter. Tighten securely.
- Ensure all connections are firm to prevent loose contacts, which can cause sparks or overheating.

5.2 Mounting the Inverter
For optimal performance and safety, the inverter should be installed horizontally. This allows for proper airflow and heat dissipation. Ensure the mounting surface is stable and can support the weight of the inverter.
6. Operating Instructions
6.1 Powering On/Off
- To Power On: After connecting the inverter to the battery, press the main power switch to the 'ON' position. The LCD display will illuminate, showing operational data.
- To Power Off: Press the main power switch to the 'OFF' position. The LCD display will turn off.
6.2 Using AC Outlets, USB, and Type-C Ports
- Once the inverter is powered on, you can plug your AC appliances into the three standard AC sockets.
- Connect your USB-powered devices to the dual USB ports or the Type-C port for charging. These ports are live whenever the inverter is connected to a battery, even if the main AC output is off, allowing for convenient charging without activating the full inverter.
6.3 Wireless Remote Control
The included wireless remote control allows you to conveniently turn the inverter on or off from a distance of up to 100 meters.
- Important: Before using the remote control to turn on the inverter, ensure the main power switch on the inverter itself is in the 'OFF' position.
- Press the 'ON' button on the remote to activate the inverter.
- Press the 'OFF' button on the remote to deactivate the inverter.
- The remote uses an A23 size battery (not included).
