Battery Storage

Store surplus solar, ride through outages, and shift expensive peak energy to cheaper hours.

UL 9540 / 9540A compliant TOU arbitrage & backup VPP‑ready

Why add storage?

Backup power

Keep critical loads (lights, IT, refrigeration, HVAC) running in outages.

Bill savings

Charge off‑peak, discharge at peak. Reduce demand charges in commercial sites.

Solar self‑consumption

Use more of what you generate, even after sunset. Lower export penalties.
