Formerly known as the OGK-MAX, the newly branded PRIME MAX is designed for those who need more than just the essentials. As the "middle ground" of our PRIME line, it offers nearly double the solar input and expanded battery storage to handle larger daily demands. Whether you are looking for high-performance home backup, deeper peak shaving, or a robust power system for a large off-grid cabin, the PRIME-MAX can handle it.

Like all our kits, the PRIME 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, designed so that a homeowner can comfortably handle the majority of the installation, while remaining simple enough for a local professional to step in and finalize the connection quickly.
