Every Sunbox kit ships with a permit pack: a one-line electrical diagram, the panel and inverter spec sheets and a roof layout drawn for your address.

Before you order

Check whether your city wants a licensed electrician to make the final connection. Most Colorado cities allow homeowner installs on your own home with an electrician for the tie-in.

The utility

  • Labels on the isolators and the main panel — they ship in the kit.
  • Every rail grounded, every cable clipped.
  • The permit pack printed and on site.
