Camper Van Electrical System

Camper van electrics, can be one of the most daunting parts of the van conversion build, with our build we didn’t want to use gas or have gas tanks in our build, we wanted to be able to stay off grid for a decent amount of time and not have to worry about having site electrics available.

We have a fridge/freezer/microwave oven and an induction hob for cooking, as well as our 12v demands.

I worked out our total wattage requirements, which came out at 3.5KW if we had everything on, not that we would ever do that and there our in line fuses to prevent all appliances being on at the same time, just me I’m always over safety.

So that’s why we went for a 4KW pure sine wave inverter to give us our mains 240V supply, we have four 100A Yuasa EFB batteries wired in 2 banks in parallel, giving 2 banks of 200A X 12V. each bank is then wired in series giving us 24V X 200A output.

The 24V output goes to our 24V X 4KW mains inverter, and also through a DC to DC converter (24V to 12V) and feeds our low voltage appliances. we also have 2 Victron smart chargers for maintaining the the batteries through the winter months.

There will be a full in depth video (soon) of the electrical system, on our YouTube channel if you are interested in finding out more. youtube.com/@offgridexplorer9495
