Energy Storage Systems

Princeton Power's Energy Storage System (ESS) makes adding a turnkey energy storage component to any facility or project fast, easy and cost-effective. The ESS consists of multiple inverters and battery racks in a weatherproof enclosure, sized to customer requirements by both power (kWs) and energy (kWhs). The system is built on 100kW inverter building-blocks and can support several battery technologies, including sealed lead-acid, large-format lithium-iron-phosphate and hybrid lead-acid. Each ESS includes all disconnects, connection points and safety systems needed based on the size of the system and technology employed.

Our application team will recommend the optimal ESS for your unique needs with minimal installation and engineering required. Each ESS comes equipped with a web-based monitoring and control system, which allows real-time views of operating data and integration with Building Management Systems, SCADA systems, and data services, such a PJM Interconnection signals. The ESS is compatible with a variety of third-party monitoring and controls platforms.

ESS configurations are tailored for:

  • Microgrids
  • Facility backup power
  • Grid frequency regulation
  • Solar/PV support
  • Wind grid support
