Frequently Asked Questions
What are off-grid electrical wiring diagrams?
Off-grid electrical wiring diagrams are detailed, system specific schematics that show how every component in an electrical system connects and operates together. They cover charging sources, leisure batteries, inverters, protection devices, providing a clear and safe layout for installation.
What types of builds are wiring diagrams suitable for?
Our wiring diagrams are suitable for campervans, motorhomes, off-grid cabins, tiny houses, and other small-space or off-grid builds. Each diagram is designed specifically for the build type, layout, and intended use rather than following a one-size-fits-all template.
Why is electrical safety so important in off-grid systems?
Off-grid electrical systems combine multiple power sources, stored energy, and confined spaces. Without correct design, this can introduce serious safety risks. Our wiring diagrams prioritise electrical safety and compliance, ensuring correct cable sizing, protection and isolation, all before installation begins.
Each diagram is also supplied with a clear installation guide, helping builders and installers conform to UK electrical safety standards and ensure the system is installed to the components specification.
Are your wiring diagrams compliant with UK electrical standards?
Yes. All wiring diagrams are designed with UK electrical safety standards and best practice in mind, including relevant elements of BS7671, where applicable. Furthermore, they are also designed to highlight any specific component specification the installer may need to be aware of. This helps ensure systems are safe, logical, and suitable for inspection, testing, and long-term use.
What does the wiring diagram process involve?
The process starts with a 30-minute Zoom consultation to understand how the system will be used, followed by power calculations and system design. We then produce a bespoke wiring diagram tailored to your build, components, and future plans, with clarification and support available if needed.
Can I use a wiring diagram if I’m building the system myself?
Yes. Many customers use our wiring diagrams for DIY installations, while others work with professional converters. The diagrams are designed to remove guesswork and provide clear guidance, helping ensure systems are installed correctly and safely.
Do you only design wiring diagrams for Victron systems?
Yes. Our wiring diagrams are designed exclusively around Victron Energy systems, alongside other high-quality, compliant components such as Blue Sea Systems. This ensures reliability, consistency, and compatibility with modern off-grid electrical installations.
Each diagram is also supplied with a clear installation guide, helping builders and installers conform to UK electrical safety standards and ensure the system is installed to the components specification.
Why do you only work with Victron Energy components?
Using proven, high-quality components allows us to design systems that are safer, more reliable, and easier to support long-term. Victron Energy and manufacturers such as Blue Sea provide robust, well-documented equipment that supports correct system design, monitoring, and future upgrades.
Can wiring diagrams be used for future upgrades?
Yes. Wiring diagrams are designed with future expansion in mind, allowing additional charging sources, batteries, or loads to be added safely without redesigning the entire system.
Do wiring diagrams include installation or certification?
Wiring diagrams are a design service and do not include installation or certification by default. However, they can be used alongside our installation, inspection, and testing services, or by professional installers working to the same safety-led approach.
