Horsebox & Racetruck Electrical Systems

Electrical Systems for Horseboxes & Racetrucks

Horseboxes and racetrucks often rely on electrical systems to power living areas, equipment and support facilities while travelling or at events.

At Keltie Campers Ltd, we install and upgrade electrical systems for horseboxes and motorsport support vehicles, improving reliability and providing dependable off-grid power.

These systems allow vehicles to operate comfortably without relying on campsite or venue power connections.

Off-Grid Power for Support Vehicles

Many horseboxes and racetrucks require electrical systems capable of powering lighting, refrigeration, equipment charging and living areas while parked away from mains power.

We design electrical systems that combine modern lithium batteries, inverter power and efficient charging systems to support these requirements.

Lithium Battery Upgrades

Lithium batteries are particularly well suited to support vehicles that require large amounts of usable power. Compared with traditional batteries they offer significantly more usable capacity, faster charging, longer service life and reduced weight.

Lithium systems can dramatically improve how a horsebox or racetruck electrical system performs, particularly for vehicles used for extended periods at shows, events or race meetings away from mains power.

Charging & Solar Systems

Charging systems are critical to maintaining reliable power. We install systems that allow batteries to charge effectively from alternators, mains power and solar installations where suitable.

This ensures the electrical system remains reliable during travel and at events.

Frequently Asked Questions — Horsebox & Racetruck Electrical Systems

What electrical systems do horseboxes typically need?
Most horseboxes need systems capable of powering lighting, water pumps, compressor fridges, phone and device charging, and in some cases 230V appliances. For extended event use, lithium battery storage paired with an inverter charger and solar is the most reliable solution.

Can you install Victron systems in horseboxes?
Yes. We regularly install Victron inverter chargers, MPPT solar controllers and monitoring systems in horseboxes and specialist support vehicles. As Scotland's Victron Approved Installer, we have the expertise to design and build these systems correctly.

How much battery capacity does a horsebox need?
This depends on the equipment fitted and how long the vehicle is used away from mains power. Many horsebox installations use between 200Ah and 400Ah of lithium capacity. We can help calculate the right size based on your power usage.

Do you work on racetrucks and motorsport support vehicles?
Yes — we carry out electrical installations and upgrades on racetrucks and motorsport support vehicles. These vehicles often have similar electrical requirements to horseboxes with the addition of workshop equipment and compressor power.
