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 quote and BOM start where the sale is strongest.

Tick what you use and set how many hours a day it runs. Untick "Same time" for things never used together with others. 12V items run straight from the battery, with no inverter needed.

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.
