HNU Energy, International Battery team for solar and energy storage project

Allentown, Pa., February 8, 2010 — International Battery teamed with HNU Energy to participate in a solar power generation and energy storage project in Maui, Hawaii.

The project, recently put into operation, will assess the effectiveness of storing solar energy using new, more-efficient battery technology.

The renewable energy system is comprised of sixty 224-watt photovoltaic panels, a bi-directional 3-phase inverter system, and a charge controller network provided by system integrator HNU Energy, located in Maui, Hawaii.

International Battery supplied a 48V, 16.4kWh lithium-ion based energy storage system — complete with battery management and controls — to store the energy generated from the solar array.

The energy storage system includes four battery modules totaling 32 160Ah lithium iron phosphate cells and a battery management system that is integrated into a standard Electronics Industry Alliance style 19″ portable rack mount chassis and enclosure.

For easy management and monitoring of the batteries, International Battery’s comprehensive BMS monitors and controls the entire battery system.

Key to overall system performance is knowing the health and charge state of the individual battery cells as well as understanding the temperature, depth of discharge and charging status.

HNU Energy, a unit of HNU Photonics, specializes in the commercialization and integration of solar PV technologies and high-efficiency LED lighting products, made available directly from our warehouse and distributors throughout North America. HNU is currently selling 5kW-100kW modular solar PV “kits” scalable to over 1 MW.

Headquartered in Allentown, Pa., International Battery is a U.S. manufacturer, designer, and developer of large-format lithium-ion rechargeable cells and batteries for use in a wide range of transportation, industrial, electric utility, smart grid and military applications, employing a uniquely environmentally friendly manufacturing process.
