Kyocera and Nichicon have completed an agreement for Kyocera to begin domestic sales this summer of a new energy management system (EMS) which combines Kyocera's highly reliable solar power generating systems with Nichicon's long-lasting, high-capacity lithium-ion battery storage units. Designed for the Japan market, the new system responds to the growing demand for residential energy storage equipment following the March 11 disasters. Kyocera will begin sales in Japan this summer.
Using and regulating a solar power generating system with battery storage requires a power inverter and sophisticated energy-management technology. The EMS developed by Kyocera is thus effective in optimizing residential energy use from those systems and utility power from the electricity grid.
The new EMS system offers various operating modes to meet the energy use patterns and needs of various customers — whether their peak energy consumption occurs in the daytime or at night and for families who want to prioritize reducing their energy bill or those who place a premium on guaranteed electricity supply. The system automatically switches to independent operation in the event of a natural disaster or electricity black-out. In the event of a prolonged black-out, the battery can be charged directly by the solar modules during the day, allowing users to draw from the battery at night or during inclement weather.
Residential energy storage.
The system uses a lithium-ion battery, which can last roughly five times one longer than conventional lead-acid batteries. The battery has a high capacity of 7.1kWh, weighs roughly 200kg and has a size of 120H x 90W x 35D (centimeters)*2.
Summer 2012 in Japan only.
