Installation

From the first visit to the first test outage.

Five steps. You are needed for three of them, for under ten hours in all, and the power is off for about two.

45 minutes · One installer

Site visit

An installer measures the wall, opens your main panel and maps the conduit run. You get the final price in writing before anyone drills.
Two to four weeks · We file it

Permit and paperwork

We file the electrical permit and, if you have solar, the paperwork with your utility. Your city sets the pace; you do nothing.
Six to eight hours · Two installers

Installation day

They fix the bracket to the studs, lift the K13 onto it, run one conduit to the panel and fit the backup switch by the meter. The power is off for about two hours.
30 minutes · Your city, with us there

Inspection

The city inspector checks the work. We meet them at your door, so you do not have to take the morning off.
15 minutes · You and the installer

First test outage

We switch the grid off at the main while you watch. The house carries on, and the light on the front shows what is left.

What your home needs

A wall, a panel and three feet of floor.

The installer checks all of it at the site visit, and tells you then if something has to change.

A wall or a slab: 29.5 inches of wall that can carry 282 lb on two studs. If it cannot, the K13 stands on the floor on steel feet.
Clear space: Three feet of open floor in front of it, the working space an electrician needs at any panel.
Your main panel: Any 120/240 V split-phase service. The backup switch goes between your meter and the panel.
Indoors or out: The case is rated NEMA 3R, so an outside wall works. It runs from −4 °F to 122 °F.
Solar, if you have it: Any grid-tied solar inverter. The K13 connects on the AC side of your panel.
Where we install: The lower 48 states and the District of Columbia. Alaska and Hawaii are not served yet.

Forty-five minutes at your house. You get the final price in writing before anyone drills.
