Axion Power International announced the release of its newest residential energy storage system, further broadening its consumer product line. The residential system features the latest generation of Axion’s PbC Batteries and works with inverters from leading manufacturers. Power levels are available between 4 and 8 kW and can be expanded by paralleling multiple inverters to meet a variety of residential and light commercial needs. Each system comes with a five-year full and five-year prorated battery warranty and is designed for more than 10 years of use.
Axion Power’s residential energy storage system adds flexibility and dependability to solar energy use, making solar a viable alternative to other energy sources, storing excess production for later use. This allows the homeowner to be energy independent by maximizing self-consumption of solar, avoiding high peak energy rates and providing security in the event of a power outage.
Comprised of 15 PbC Batteries, these systems are reliable and virtually maintenance free. PbC Technology allows the system to operate in a partial state of charge and offers rapid recharge. In addition, PbC boasts a long cycle-life allowing for years of steady use resulting in a low lifetime cost of ownership. The base 15 battery cabinet provides 7kWh (20-hour rate) of usable energy storage and can be customized for larger sizes. Axion’s residential energy system, along with products such as their off-grid solar light kit (released earlier this year), can be combined to create smarter energy independent homes.
Axion’s 7 kWh residential energy storage solution includes 15 PbC Batteries with complete battery cabinet and is now available for order with an introductory price of $7,995. The system can be professionally installed with a new or existing solar system.
Axion Power is a technology leader in lead-carbon energy storage. Axion’s patented lead carbon battery is the only advanced battery technology with an all carbon negative electrode. Axion’s negative electrodes are designed to be directly substituted for lead acid negative electrodes producing the unique benefits of the Axion carbon technology. Axion Power’s primary goal is to become the leading supplier of carbon electrode assemblies for lead-acid battery companies around the world. For more information, visit
