Energy Storage Systems
Princeton Power's "Energy Storage System" (ESS) was developed to make 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 (kW's) and energy (kWh's). 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.
ESS configurations are tailored for:
- Microgrids
- Facility Backup Power
- Grid Frequency Regulation
- Solar/PV support
- Wind Grid Support
- Diesel Generator Integration
Our application Engineering Team can quickly specify an ESS that meets customer requirements, and provide a turnkey system 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.
