Overview

Power that grows with you.

Formerly known as BPK-PLUS, the newly branded SELECT PLUS is an exceptional choice for homeowners looking to fully integrate with the utility grid while maintaining robust battery backup. This system is designed for maximum flexibility, functioning seamlessly off-grid or through grid-interconnection. This makes it the ideal solution for residents in states where selling power back to the utility offers a strong return on investment.

Every SELECT Power Kit comes complete with all the essential parts and pieces needed to get your system up and running. We have engineered these kits for a truly DIY-friendly experience, allowing homeowners to comfortably manage the majority of the installation. The streamlined design also ensures that a local professional can step in and finalize the grid connection quickly and easily.

Typical Uses: What Can It Run?

  • Grid-Tie & Energy Offset: Automatically export excess solar production to the grid to significantly lower or eliminate your monthly utility bill.

  • Intelligent Bill Savings: Utilize your 20kWh+ battery reservoir during "peak" hours to avoid the highest electricity rates from your utility provider.

  • Essential Home Backup: Provides 10kW of continuous backup power for critical circuits, including lights, refrigerators, and security systems.

  • Grid Outage Support: Keeps your home running smoothly and comfortably during neighborhood power failures.

  • Medical Devices: Provides dedicated, reliable power for CPAP machines or other essential home health equipment that requires zero downtime.
