SEOUL--South Korea's Samsung SDI Co. (006400.SE), a maker of the rechargeable batteries used in consumer electronics and vehicles, said Wednesday it signed a memorandum of understanding to supply energy storage systems to German solar power inverter maker KACO new energy GmbH from the end of this year, in what will be the Korean firm's first entry into the European market.

Samsung SDI said it will supply energy storage and battery management systems to the German firm. Inverters transform the direct current output of a solar panel into alternating current, which most appliances use.

KACO is based in Neckarsulm, Germany. The two companies also have an agreement to further cooperate in the development of energy storage systems, Samsung SDI said.

In October last year, Samsung SDI signed an agreement with Japan's Nichicon Corp. to supply energy storage systems to Japanese households from the first half of this year. The Korean battery maker said at the time it aimed to have a more than 30% share of Japan's household energy storage system market by 2014.
