Onboard power for motorhomes, vans and specialist vehicles
Keep the lights on, the fridge cold or your tools running when you’re parked away from a mains hook-up. JY Group designs, supplies and fits off-grid power systems for motorhomes, campervans, work vans and specialist vehicles.
How it works
A dedicated leisure battery stores energy for the back of the vehicle. Depending on your setup, roof solar panels can recharge it in daylight, a DC-to-DC charger can top it up while you drive, and a mains hook-up can recharge it when one is available. An inverter turns battery power into mains electricity for compatible equipment.
What we can fit
- Mains and low-voltage power. 230–240 V sockets for appliances and chargers, dedicated 110 V supplies for compatible site tools, and low-voltage feeds for lighting, fridges and water pumps.
- Battery and charging systems. Lithium leisure batteries, inverters, roof solar, charging while driving and battery monitoring.
- Heating, cooling and water. We can integrate air conditioning, Eberspächer diesel night heaters, sinks and onboard water systems into the fit-out.
Tell us what you need to run, what may be on at the same time and how long you spend parked. We’ll size the battery, inverter and charging system around your use. Air conditioning and other high-draw equipment need particular attention because they can shorten battery runtime considerably.

Vet in a Van for Longridge Vets
We worked with the directors of Longridge Vets to build a mobile veterinary surgery for their Vet in a Van service. The vehicle gives their team a place to see pets and their owners at community locations, with power and facilities on board for appointments away from a mains hook-up.
- Off-grid power. A lithium battery system, inverter and 240 V mains supply, with roof-mounted solar panels to help recharge the batteries.
- Internet and networking. We installed an onboard internet connection, Wi‑Fi and a wired Ethernet network.
- Clinical facilities. Air conditioning, a refrigerator for temperature-sensitive medicines, and a sink with running hot water and waste collection.
- Visibility and access. External CCTV viewable from the rear working area, plus lighting around and beneath the vehicle to illuminate the approach for pet owners.
- Provision for X-ray equipment. Wiring installed as part of the fit-out.
