1.6kW Off-Grid Solar Kit - Dual Rich Solar 3K Inverters - 5-7kWh Lithium Battery [CORE MAX]

Formerly known as RPK-PLUS, the newly branded CORE MAX is designed for places where a grid connection is impossible or impractical. As the "middle ground" of our CORE line, it offers increased solar input with dual inverters to handle more frequent use and larger daily demands. Whether you are powering a high-use workshop, a medium-sized off-grid cabin, or a remote job site, the CORE-MAX provides the expanded power foundation you need for total independence

Like all our kits, the CORE MAX 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 every cable, connector, and adapter along with simple, easy-to-follow instructions and wiring diagrams. While it’s designed to be straightforward enough for a homeowner to handle, the completeness of the kit also makes it super simple for a local professional to set up quickly if you choose to hire one.
