Several weeks ago, Kyocera Corporation announced its plans to sell two different energy storage units to residential customers in Germany. The 4.8-kilowatt-hour and 7.2-kilowatt-hour units will be available in May, sold through its German distributor Energetik Solartechnologie-Vertriebs.
Kyocera’s lithium-ion batteries are the core of the new systems, which feature inverters from Energetik and Datensysteme’s energy monitoring software and hardware.
Kyocera claims that the units will achieve a charging efficiency of 97 percent. This, it says, is due to the multi-inverter, which incorporates functions of both a solar power inverter and battery inverter.
