Off-Grid Caravan Power Without the Generator

Free camping in a caravan is better without a generator rattling in the background. Zeliox delivers 240V power for fridges, lighting, water pumps, and device charging — silent, solar-compatible, and compact enough to fit in a caravan storage bay or tow vehicle.

THE PROBLEM

Caravan Power Systems Are Often an Afterthought

Many caravans come with basic battery setups that struggle to run a fridge overnight, let alone lights, pumps, and chargers. Adding capacity usually means an expensive upgrade, a separate solar regulator, and more wiring — or falling back to a generator that ruins the peace of a free camp.

THE Solution

Compact Power That Fits in the Van or Tow Vehicle

Zeliox is compact enough to mount in a caravan storage bay or in the tow vehicle, providing 240V power for all the essentials. Built-in MPPT solar charging means you can top up during the day from roof-mounted or portable panels, extending off-grid stays.

The Zeliox Advantage

Free camping has become more popular than ever, and for good reason — no booking fees, no crowded sites, and the freedom to pull up wherever the map says you can. But free camps rarely have powered sites, and that leaves caravanners with the same old choice: a generator or a battery system that might not last the night.

Zeliox is compact enough to mount in a caravan storage bay or in the tow vehicle, so it does not eat into living space. The system powers a standard caravan fridge, LED lighting, water pump, and device charging — the essentials that keep a caravan comfortable off-grid. During the day, roof-mounted or portable solar panels feed the built-in MPPT regulator. When you hitch up and move, the alternator in the tow vehicle tops up the battery on the drive to the next stop.

Unlike a generator, Zeliox runs at zero decibels — so you can run the fridge through the night without waking yourself up, let alone the neighbours. And because there is no engine to service, no oil to change, and no fuel to store, the maintenance overhead is essentially nil. For anyone who has carried jerry cans of generator petrol in a caravan boot, that alone is worth the switch.
