Overview

Power that grows with you.

Formerly known as the OGK-PRO, the newly branded PRIME PRO is the pinnacle of our PRIME line, engineered specifically for those who demand the absolute best in high-capacity backup and grid-interactive performance. Whether your goal is to fully protect a large family home with seamless backup, transition to a high-powered off-grid lifestyle, or drastically lower your utility bill through smart energy management, the PRIME PRO is the definitive choice.

Like all ShopSolar kits, the OGK PRO includes every major component and specialized part required to get your system up and running. We have engineered this kit for a truly DIY-friendly experience, ensuring a homeowner can comfortably manage the majority of the installation. This streamlined design also makes it simple for a local professional to step in and finalize the connections quickly, saving you time and expensive labor costs.

Typical Uses: What Can It Run?

  • Whole-Home Autonomy: Provides the significant energy and surge capacity needed to run central air conditioning, well pumps, and electric water heaters.

  • Advanced Peak Shaving: Utilize intelligent software to shift your heaviest loads to battery power during peak utility hours, significantly slashing your monthly bill.

  • Multi-Day Backup: With up to 32kWh+ of storage, you can keep a typical home running for over 24 hours (or much longer with solar) during a total grid failure.

  • Commercial & Industrial: Reliable power for small businesses, medical clinics, or retail spaces that require zero-downtime protection.

  • EV Charging: Generate enough daily solar harvest to fully charge electric vehicles directly from your own roof.

  • Outbuildings & Structures: Reliable power for shops, garages, greenhouses, barns, and ADUs across your property without the need for expensive trenching or new utility lines.
