International Battery, a U.S. manufacturer and developer of large-format lithium-ion rechargeable batteries, today announced they have recently 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 state-of-the-art 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 (LFP) cells and a battery management system (BMS) that is integrated into a standard Electronics Industry Alliance (EIA) 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.
Storing energy from renewable sources is vital for managing variations in electricity production, improving power quality and stabilizing the power grid. International Battery is helping communities, organizations and utilities take advantage of the company’s large format prismatic lithium-ion technology and battery management systems to maximize the energy potential of renewable systems.
