    Hi, how long is the max cable run from leisure battery to the inverter? My inverter was only supplied with very very short connecting cables. Thanks for any advice. BUSBY.

    How big is the Inverter ??
    Usually you try and keep them as short as possible to the battery and you have to be careful that you use the correct thickness of cable. To thin and to much power = "fire".....
    In my old van I kept the inverter by the battery and ran a 4 way mains extension cable to where I needed it..

    If you need / want to extend the cables you need to consider

    1. Max Current ,

    = Watts / voltage .. for example a 1,000 watt inverter = 1000/12 so it will pull about 84 Amps

    2. Cable run length..

    when you have this info. use this calculator to determine the optimum size of cable..

    you should also fit a suitable sized fuse at the battery end of the positive cable..


    if unsure, post the size of the inverter and the cable run length

    Its most important to keep the cable length between the battery and inverter as short as possible. Using the supplied cables is a good idea. The mains cable between the inverter and the item being powered can be as long as you like, as it will only be carrying 1/20th of the current.
