To demystify this process and ensure a successful electrical setup, let’s delve into the world of campervan wiring, with a focus on a comprehensive campervan wiring diagram.

Here at Nomadic Leisure not only have we spent weeks researching and learning about campervan electrical systems, but we have implemented and installed a variety of electrical systems in many vans first hand.

Our Must Have Campervan Electrical Components

To understanding the basics of what you require for you campervan electrical system begin by familiarising yourself with the basics of campervan wiring. Identify essential components, such as batteries, inverters, solar panels, and appliances. Understanding the electrical demands of your campervan layout is key to creating an efficient and reliable system.

We’ve compiled a list of essential products that are integral to every campervan conversion we’ve undertaken and find indispensable.

Victron LiFePO4 Battery 12,8V/200Ah Smart (BAT512120610)

LiFePO4 Batteries

We would now always choose LiFePO4 batteries over any other. Unlike traditional AGM or other lithium batteries, LiFePO4 batteries offer unparalleled advantages: extended lifespan, rapid charging, lightweight design, deeper discharge capabilities, consistent voltage output, and eco-friendly composition. Further down we will go onto talk about how to size your leisure battery for your campervan.

Battery to Battery Charger

In a campervan setup, a battery-to-battery charger is indispensable for efficient energy management. This device ensures optimal charging of your auxiliary battery while driving, addressing the limitations of alternator charging alone. With a battery-to-battery charger, you can control the charging process, ensuring that your leisure battery receives the correct voltage and charge profile. This not only maximises charging speed but also protects your vehicle's starter battery from over-discharge. The result is a reliable and balanced power system in your campervan, providing sustained energy for your adventures while on the road.

Solar Charge Controller

A solar charge controller is an essential component in a campervan's solar power system, serving as a guardian for your batteries. Its primary function is to regulate the energy flow from solar panels to the batteries, preventing overcharging and damage. This device optimizes the charging process, ensuring that your batteries receive the right voltage and current, thus extending their lifespan. In a campervan, where energy autonomy is crucial, a solar charge controller plays a pivotal role in harnessing the sun's power efficiently, providing a sustainable and reliable source of energy for your on-the-go lifestyle.

Multiplus Inverter-Charger

A MultiPlus inverter-charger is a game-changer for campervan enthusiasts seeking versatile and efficient power management. Unlike a Phoenix inverter, the MultiPlus integrates both inverter and charger functions seamlessly, allowing for simultaneous charging from various sources, including shore power and solar. This ensures optimal energy utilisation, providing continuous power whether connected to the grid or off-grid. The MultiPlus also offers advanced features like power assist and uninterruptible power supply (UPS) functionality, enhancing its flexibility. With the MultiPlus, campervan owners enjoy a comprehensive and intelligent power solution, enabling a reliable and customizable energy system that adapts to diverse travel scenarios.

Battery Monitoring System


A battery monitoring system, exemplified by the Victron Cerbo and GX Touch 50, is indispensable in a campervan for precise control and insight into your power setup. These systems allow real-time monitoring of battery status, energy consumption, and charging rates. This information is crucial for preventing over-discharge, optimizing energy usage, and ensuring the longevity of your batteries. The Cerbo and GX Touch 50 provide a user-friendly interface, enabling campervan owners to make informed decisions about power consumption, energy sources, and overall system health. With these monitoring tools, you gain a comprehensive understanding of your campervan's energy dynamics, empowering you to manage your power resources efficiently during your on-the-road adventures.

Solar Panels


Installing solar panels on a campervan is a transformative investment that enhances both sustainability and freedom during your travels. Solar panels harness sunlight to generate clean, renewable energy, providing an independent power source for charging batteries and running appliances. This self-sufficiency reduces reliance on traditional power outlets, allowing for extended off-grid adventures.

Campervan Electrical Kit Accessories

In the intricate landscape of campervan electrical setups, small accessories play a pivotal role in ensuring a comprehensive and seamlessly functional system. These seemingly minor components are the unsung heroes, bridging gaps, and enhancing the overall efficiency of your electrical kit. From reliable connectors and fuse holders to cable management solutions, these small accessories are the linchpin that transforms a collection of components into a reliable, well-integrated power system. Embracing the importance of these details ensures not only the longevity of your equipment but also streamlines the installation process, making small accessories an indispensable part of any truly comprehensive campervan electrical kit.
