This fully integrated ZESS power system will be used in an on-grid configuration with Photovoltaic (PV) renewable energy generation inputs for use to provide both daytime and nighttime power to the host building's lighting system. The ZESS POWR PECC system will control energy and power inputs, direct energy flows to and from energy storage, regulate clean power to the lighting system and when available, send excess energy to the site's larger electrical distribution system.

ZBB's Vice President Sales and Marketing, Mr. Kevin Dennis said, "This project is the initial 24hr photovoltaic powered system for a US government facility, that firmly places energy storage as the cornerstone for an integrated, renewable energy system that not only can shift energy outputs across the daily use and generation cycle associated with PV, but has the capabilities to send surplus power to either storage or to the grid, based on time of day or other priorities. Though this is only the initial demonstration system, the architecture used by SEI for this project is readily scaled up to much larger systems capable of producing, storing and managing renewable energy for entire sites."

Mr. Mark Kelly, Vice President / Program Manager for the Energy Technologies group at SEI said, "ZBB's system approach for integrating next-generation zinc-bromide energy storage units and renewable energy made this a straight-forward design and implementation for our engineering team that wasn't available previously. The ZESS POWR system will make renewable energy more stable and valuable as a generation source."
