Complete Power System with 600Ah Lithium and 3000VA Inverter

Complete Power System with 600Ah Lithium and 3000VA Inverter: a pre designed system with 600Ah of lithium, a 3000VA inverter charger, DC to DC charger, MPPT controller, battery monitor and a fused distribution board.

A complete electrical system sized for the way you use the van, with the batteries, charging and distribution designed together rather than bought one piece at a time. We size it from how many days you want to stay off grid and what you run, and we send the diagram with it. This part is not van specific, and the listing says where the mounting position matters.

Fitting

Every positive cable is fused as close to the battery as possible, cable is sized for voltage drop rather than just current, and anything carrying mains voltage from an inverter or hook up goes through an RCD. If you are not confident with any of that, buy the fitted option; a badly wired 12V system can start a fire as easily as a mains one. Lithium iron phosphate batteries weigh about half as much as lead acid for the same usable capacity and can be run much flatter without damage. They must not be charged below freezing, which is why the self heating versions exist and why they are worth it in a van that is used in winter. They also need a charger and a DC to DC charger with a lithium profile. Conversions are heavy. Batteries, water, furniture and insulation can add 500 to 800 kg, and a van that starts at 3.5 tonnes gross can end up overweight before anyone has packed a bag. Every listing states its weight, and it is worth weighing the empty van at a public weighbridge before the build begins. Tell your insurer about the conversion as it progresses, not afterwards. Since 2019 the DVLA has been strict about reclassifying vans as motor caravans on the V5C, and most specialist insurers will cover a converted van as a camper whatever the V5C says, provided they know what is in it. We supply and fit camper conversion parts for panel vans, and we build and live in our own. We are not Ford, Mercedes-Benz or Volkswagen and are not appointed by them; the van names describe fitment. Everything here is chosen for vans that get used all year, including the British winter, and we say plainly where a cheaper part would do the job.

Which version to buy

Parts Only is the parts delivered with our wiring diagram or fitting notes, for a self build or your own installer. There is one version of this because it is the one we fit in our own vans.
