Frequently Asked Questions

  • Do you work on caravans, motorhomes, and campervans?

    Yes, we handle all types of recreational vehicles, as well as marine systems and off-grid tiny homes.

  • Can you diagnose from photos first?

    In many cases, yes. Photos of your setup often reveal common issues like undersized cabling or incorrect fuse placement, allowing us to give you a preliminary assessment before we arrive.

  • Do you supply parts if needed?

    We carry a range of common fuses, cables, and connectors. If a specific part is needed, we can source it or work with what you already have.

  • How long does troubleshooting take?

    Most diagnostics are completed within 1 to 2 hours. Complex issues may take longer to trace.

  • Do you do 240V wiring?

    Our primary focus is the DC side (Solar, Batteries, Chargers). For 230/240V AC mains installations or repairs, a registered electrician is required. We can refer you to a local partner for this.
