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.
