Mate, this made wiring my van so much easier. I’ve built a few setups before, but I always just winged it a bit. Followed the diagram and it worked first go. Bloody brilliant.

I’m an electrician by trade and grabbed this out of curiosity — honestly, it’s really well put together. Would recommend it to anyone doing a van conversion themselves.

Thanks Marcel, legend

Loved that it shows both 12V and 240V systems on the same plan. I’d been trying to figure out how to connect my inverter to shore power safely

We’re doing our first van build and honestly had no idea where to start with power. This made everything click. The DC-DC charger setup and solar layout were spot on. Thanks for making something normal people can actually understand!
Marcus –
Super helpful. Covers both 12V and 240V properly, which most guides skip over.
Naomi –
Such a good resource. I’m not usually one to leave reviews but this deserves it. Made something super technical feel easy to follow.

I would have loved the products linked into the diagram, but maybe that’s coming in the future. Apart from that, it’s just what I needed
