Please read this manual thoroughly before installation and use.
2. Safety Information
Adhering to safety guidelines is crucial when operating power inverters. Failure to do so may result in personal injury or damage to equipment.
- Ventilation: Ensure the inverter is installed in a well-ventilated area to prevent overheating. Do not block ventilation openings.
- Cable Sizing: Use appropriate gauge cables (4 AWG or thicker for this model) to connect the inverter to the battery. Undersized cables can lead to overheating and power loss.
- Polarity: Always connect the positive (+) terminal of the battery to the positive (+) terminal of the inverter, and the negative (-) terminal of the battery to the negative (-) terminal of the inverter. Reverse polarity can cause severe damage.
- Grounding: Properly ground the inverter chassis to a reliable earth ground or vehicle chassis.
- Overloading: Do not exceed the inverter's continuous power rating of 4000W. While it supports a 7000W surge for 2 seconds, sustained overload can trigger protection mechanisms or damage the unit.
- Water and Moisture: Keep the inverter away from water, rain, snow, or excessive moisture.
- Children: Keep the inverter out of reach of children.
- Certified Components: This inverter features ETL-listed transformers, UL458-certified fuses, and FCC-approved anti-interference technology for enhanced safety.

4. Setup and Installation
Proper installation is critical for the safe and efficient operation of your inverter.
4.1 Choosing an Installation Location:
- Install the inverter in a dry, cool, and well-ventilated area.
- Avoid direct sunlight, heat sources, and moisture.
- Ensure sufficient clearance around the inverter for airflow.
4.2 Battery Connection:
- Ensure the inverter is turned off before making any connections.
- Connect the included battery cables to the inverter's DC input terminals. Ensure correct polarity: red cable to positive (+), black cable to negative (-).
- Connect the other ends of the battery cables to your 12V battery. Again, ensure correct polarity. Use 4 AWG or thicker cables for optimal performance and safety.
- Secure all connections tightly to prevent loose contacts, which can cause overheating.
- Connect the inverter's grounding terminal to a reliable earth ground or vehicle chassis.

4.3 Remote Control Connection:
Plug the RJ10 cable from the remote controller into the designated RJ10 port on the inverter. The remote allows for convenient power control and monitoring from a distance.
4.4 AC Output Connections:
- Plug your AC appliances into the 4 standard AC outlets on the inverter.
- For high-power devices requiring a direct connection, use the 40A hardwire terminal. Consult a qualified electrician for hardwire installations.
- Utilize the PD36W USB-C and 3.6A USB-A ports for charging compatible USB devices.
