Shed & Cabin Build

Build your shed or cabin system

A small array, one inverter, and a battery, sized for a shed, a cabin, or a workshop with no line run out to it. The engine checks every connection live.

Ground racking

Solar panels

Pick the panel that fits your ground array. Large-format modules welcome here.

I already have panels. Use mine instead: the kit leaves the panels out, and the compatibility checks run on the numbers you type from the label on the back of your panel (or its datasheet).

Hybrid inverters

The brain that ties panels, battery, and the house together.

Batteries

LiFePO4, 48V class. Size to the loads you want to back up.

I'm supplying my own battery. Leave it out of the kit. (Must be a 48V LiFePO4 bank; a tech confirms the pairing.)

Rapid shutdown

NEC 690.12 fire-safety cutoff, required on rooftop arrays. Pick how much the panel-level units do beyond the shutdown itself.

I'm handling rapid shutdown separately. Leave the RSD units out of this kit. (NEC 690.12 still requires rapid shutdown on rooftop arrays and the inspection will look for it. A tech confirms your shutdown plan before anything ships.)

Backup generator (optional)

Feeds the system's generator input for backup power. Clean sine wave inverter generators only (under 3% THD); a conventional generator's rough power upsets the inverter's AC input. Added to your kit total; pick it again or hit the ✕ under Your system to take it back out. Hookup ratings get field verified by your tech.

Your build, live

Pick a solar panel to begin.
