Overview

Power that grows with you.

Formerly known as RPK-PRO, the newly branded CORE PRO is designed for places where a grid connection is impossible or impractical.  At the top of our CORE line, this system moves to a higher 48V platform to provide bigger output and storage capacity. Whether you are powering a full-sized off-grid cabin, a heavy-duty workshop, or a remote work-site, the CORE-PRO provides the foundation you need for total independence.

Like all our kits, the CORE PRO comes with all the parts and pieces you need to get up and running. We’ve engineered this kit for a truly DIY-friendly experience, including necessary cables and adapters along with a custom wiring setup and commissioning diagram.

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.
