How to use
Install the inverter in a well-ventilated area inside the vehicle with secure mounting to prevent movement.

Use fused connections and appropriate cable cross-sections between the battery and the inverter to minimize voltage drop and reduce the risk of overheating. Avoid continuous operation at or near the maximum rated power to extend device life. Allow adequate ventilation and do not cover the inverter while in use.
