The renewable energy system is comprised of sixty 224W photovoltaic panels, a bi-directional three-phase inverter system, and a charge controller network provided by system integrator HNU Energy.
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 inches portable rack mount chassis and enclosure. International Battery’s BMS monitors and controls the entire battery system.
Dan O’Connell, CEO and founder of HNU Energy, said: ”We’re excited to implement International Battery’s proven battery technology and management system as part of our hybrid renewable energy solution for the Maui Economic Development Board (MEDB) project.
”International Battery’s turnkey system and engineering capabilities made them a perfect partner for this project. Their ability to respond very quickly and design a system specific for this application was extremely beneficial. We are very impressed with their manufacturing process. It is based on an environmentally friendly water based process; a first in the industry.”
Ake Almgren, president and CEO of International Battery, said: ”We are pleased to partner with HNU Energy and demonstrate the effectiveness of our energy storage systems for the MEDB.
”Our lithium-ion battery modules are the ideal energy storage solution due to the high energy density, robust thermal and cycling performance as well as easy system expandability. We are very excited about our first project in Hawaii and we look forward to working with HNU Energy on many other projects in Hawaii in the near future.”
