3.2kW Off-Grid Solar Kit - Rich Solar 6K Inverter - 10kWh Lithium Battery [CORE PRO]

Shipping Late October 2026

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.
