Choose your kit

Build it around how you'll use it.

Every kit starts with the same power station. What changes is the panels, and whether it connects to your home.

  1. Pick your starting point Choose the power station on its own if you already have panels, or a kit if you are starting from scratch.
  2. Match the panels to your life Folding panels pack away for the RV and campsite. Rigid panels suit a cabin, shed or backyard. The transfer switch connects to your home.
  3. Let us help you set it up Every order comes with our setup guide and lifetime support from the team, before and long after delivery.
