Princeton Power Systems Inverters Selected by Bysolar for Frequency Regulation

Princeton Power Systems Inverters with Axion Power's Batteries Provide Battery Backup for Bysolar PV System

PRINCETON, N.J.--(BUSINESS WIRE)--Princeton Power Systems, Inc., a global leader in design and manufacturing of technology products and embedded software for energy management, micro-grid operations, and electric vehicle charging, has been chosen by Bysolar, Inc. to provide a 500kW battery inverter system for frequency regulation and emergency backup power. Bysolar is working in conjunction with Princeton Power Systems and Axion to create a battery system alongside a 575kW solar PV system at an undisclosed facility in northern New Jersey. The battery system provides power in case of a grid outage, and generates revenue with an anticipated return-on-investments of five years.


Operating in conjunction with Bysolar's solar system installation, the Princeton Power Systems 500kW Inverter system and Axion Power's (AXPW) 300kWh of batteries moderate the power transients typical from solar production. During grid outages, Princeton Power Systems' inverter solution organizes the solar and battery combination to initiate a black-start action and automatically configures a microgrid providing emergency backup power to maintain operations.

"We believe that the application of Princeton Power Systems' grid-tied inverter and battery controller, in combination with Axion Power's Lead Carbon (PbC®) battery technology, provide the most effective battery solution for frequency regulation on the grid," said Alan Cowe, President, Bysolar, Inc. "The ability to handle the repetitive high current charging and discharging in response to PJM's regulating signal, provides a robust capability for frequency regulation and automatic demand response activity."

"When configured for frequency regulation, the Princeton Power Systems 500kW inverter combined with Axion's 300kWh battery creates a revenue-generating backup power system," said Darren Hammell, Chief Strategy Officer and Co-Founder, Princeton Power Systems. "The investment in the system will be repaid within five years while providing the assurance that power will always be available should the grid be impaired."
