How to use
Install the inverter in a well-ventilated area of the vehicle, secure it to a stable surface and connect the input to the vehicle's 24 V electrical system using appropriate cabling and fuse protection. Connect the AC-powered devices to the inverter's 230 V output sockets, ensuring the combined load does not exceed the inverter's rated power.
