What are you planning for?

This changes how the battery gets charged on the road.

Install notes

Cable lengths are entered later on the wiring plan, after parts are placed on the vehicle.

What will you power?

Start from the trip that sounds most like yours. We'll tick the appliances and charging that usually go with it, then you can adjust.

Pick the customer's trip style. We pre-tick a fuller kit (and charging) so the BOM starts from a realistic build.

Tick what you use and set how long it runs each day. Time is hours and minutes in one box (for example 1.15 = 1 hour 15 minutes). Untick "Same time" for things never used together with others. 12V items run straight from the battery, with no inverter needed.

Appliance Qty Watts Hours/day Same time

Enter the load profile directly.

How long off grid, and where?

"Off grid" means days in a row without a mains hookup.

How will you charge the battery?

We'll suggest what fits your vehicle and loads. Tick or untick to change. Most setups combine two or three.

Mains hookup

UK sites usually give 10–16A. Many European sites give only 4–6A. Pull more than that and the site breaker trips.

Solar
Charging from the engine

A DC-DC charger tops up the leisure battery from the alternator while driving.
