Residential Solar Plus Storage

Battery manufacturer Encell Technology asked Nuvation Energy to provide battery management systems and engineering services to help their customer build energy storage systems for two federal buildings in Southern California. Nuvation Energy provided battery management systems, custom Stack Switchgear with site-specific safety features, and a custom controller to interface between the BMS and PCS. Nuvation Energy’s solutions enabled Encell to deploy their 1.2 Volt Nickel-Iron (NiFe) batteries into energy storage systems that provided a range of demand charge management services. By charging the battery system during off-peak hours and discharging during peak hours, the system reduces both demand and consumption charges. The Encell ESS also includes an intelligent controller that adapts the charging and discharging cycle to daily use patterns and responds to curtailment requests from the utility.

GS Yuasa chose Nuvation Energy’s Low-Voltage System Assembly and Stack Switchgear (SSG) for their solar plus storage solution installed in Bright Power’s solar photovoltaic (PV) system. The PV system was installed at Via Verde, a residential development located in the Bronx, New York City. New York City suffered from severe power outages during Hurricane Sandy in 2012. Jonathan Rose Companies and Phipps Houses, the developers of the Via Verde residences, built affordable housing that provided reliable energy to a community that was harshly impacted by the hurricane. They built a 300,000 square foot urban infill, which included Bright Power’s 66 kW building-integrated PV system. The solar system provides affordable energy to residents, cutting annual electricity costs by $13,000.
