The $1.5m solar generation and energy storage system, which will be installed at Princeton Power’s headquarters, will be controlled and connected to the Public Service Enterprise Group electric grid using Princeton Power’s Grid-tied Inverter product. The inverter and energy storage system will be housed in a mobile shipping container expandable to 1MWh of storage.
The lithium-ion batteries from International Batteries, which are claimed to contain up to 10 times more energy than other prismatic cells, will be used in the project to create a less complex system with an efficient electrical bus and low thermal management requirements, allowing compact packaging and enhanced energy density.
The company said that the battery management system will monitor the temperature and voltage of each individual cell and provide continuous balancing of the system maintaining all cells within a narrow voltage range and also contributing to system efficiency in the 85 to 90% range.
The project, which is financed in part by the State of New Jersey’s Clean Energy Manufacturers Fund, is expected to be fully operational in the fourth quarter of this year as system integration testing is now underway.
Darren Hammell, co-founder and executive vice president of business development at Princeton Power, said: “International Battery’s large-format technology and approach to clean energy storage is a perfect fit for our large-scale solar and energy storage system.”
