Description
Building an off-grid system can get confusing pretty quickly... different batteries, different chargers, different brands, different rules. And every setup is a bit different. That’s where this service comes in.
With this Custom Wiring Diagram Service, you get a wiring diagram built specifically for your setup... your components, your layout, and the way you actually use your caravan, canopy, tiny house, boat, or bus. No guesswork, no dodgy Facebook advice, no hoping for the best... just a clear, safe, AS/NZS 3001 aligned plan drawn by a sparky who lives off-grid and builds these systems all the time.
You give me your gear list and goals... I map out the whole system so you know exactly what connects to what, what size cables and fuses you need, and the right way to wire it all together.

FAQ's
Q: What info do you need from me?
A: At minimum I’ll need a list of your main components (batteries, inverter, chargers, solar, DC-DC, etc), whether it’s a caravan, canopy, tiny house, boat, or bus... and roughly what you want to run. Photos of your space or existing setup are a bonus and can help me design a cleaner layout.
Q: Can you help me choose the right gear as well?
A: Yes... if you’re still in planning mode, I recommend booking a 1-on-1 system design call as well. On that call we’ll work out what you actually need, then I’ll follow up with a custom diagram based on the final gear list.
Q: Is the diagram enough for my electrician to work from?
A: In most cases... yes. The diagram gives your sparky a clear overview of how the system should be wired, what sizes and protections are needed, and how the AC and DC sides tie together. They may still tweak things based on site conditions or local rules... but this gives them a solid starting point.
Q: Will this make my system “certified”?
A: No... the certification comes from your licensed electrician and/or inspector. The diagram is a design tool that supports a compliant install when followed and combined with good workmanship and local regulations.
Q: Can you update the diagram later if I upgrade my system?
A: Small tweaks are covered in the included revision... if you do a major upgrade later (like changing inverter size, voltage, or adding a whole new section), we can sort out a follow-up diagram at a reduced cost.
