Axion Power International Inc., the developer of proprietary lead-carbon PbC batteries and energy storage systems, has received a follow-on purchase order for four more PowerCube energy storage systems from its strategic partner, a New Jersey-based solar installer for commercial and residential markets.

The purchase order, Axion says, includes batteries, racks, wiring, a data communication system and the electronics coordination needed to outfit and install the PowerCubes.

Axion notes that each PowerCube will be tied to solar arrays that produce between 500 kW and 700 kW, storing energy produced by the arrays and providing 500 kW for frequency regulation of PJM Interconnection's grid.
