Princeton, N.J., September 26, 2012 — Princeton Power Systems announces the commissioning of a microgrid using its Optimized Energy Management System, for Scripps Ranch's Recreation Center in San Diego, California.

The microgrid is intended to provide backup power to the facility in the case of power outages, as well as minimize demand charges and provide grid support functions.

The system, consisting of two PPS 100 kW grid-tied inverters, a 100 kWh lithium-ion battery module, and the balance of components including a weatherproof enclosure and various disconnects and conduit, collects power from a 30 kW solar array to store in the batteries, and serves the facility loads through a seamless transition from grid power to battery power.
