Shop by what you are building

Start with your rig.

Tell us what you have and we show the kits that fit. A van, a bus, an RV, or a shed with no engine at all.

Why this is different

No extra. No waste. No guessing.

The hard part of an off-grid install is working out what to buy and how long every wire is. We already did that, then we boxed it.

01

Cut to length

Every cable is measured for your build and cut in the right gauge and color. You crimp and connect; you do not hunt for 4 ft of 4/0.

02

Counted, not bagged

Eighteen lugs means eighteen lugs. Fuses, ferrules, heat shrink and screws are counted per kit, so nothing is missing and nothing is left over.

03

A plan you can follow

Each kit ships with a labeled wiring diagram and an install guide. Fewer calls, fewer emails, and a result that looks like the picture.

Packaging & waste

We ship it safe, not shiny.

Cutting wire to length is already about not wasting things. The box works the same way: reused while it is still strong, paper before plastic, and nothing inside it you did not need.

Reused boxes

Strong boxes and sound packing material from our own deliveries carry your kit out, with our label over the old one.

Paper before plastic

Paper tape and paper fill by default. Plastic only where it protects something expensive, because a cracked inverter is the least green outcome there is.

Offcuts recycled

Copper offcuts go to a scrap recycler and cardboard gets another run. Your kit is measured first, so there is less of both.

The diagram is the product

Every wire labeled. Every connection named.

Wire size, length, fuse rating, lug and terminal for every connection, in the order you install them. It is the reason our customers finish and the reason our inbox stays quiet.
