KACO new energy solar inverters

KACO new energy is a globally recognized pioneer in the solar energy sector, specializing in the development and manufacture of power electronics for decentralized energy supply. Originally part of a company founded in 1914, the specific brand was established as KACO Gerätetechnik GmbH in 1999 and became famous for launching the world's first transformerless solar inverter. Its core manufacturing remains centered in Neckarsulm, Germany, though the brand has historically maintained a production and sales presence across the Americas and Asia.

In 2019, the brand reached a major milestone when it was acquired by the global technology powerhouse Siemens AG. Today, KACO new energy operates as a key subsidiary within Siemens' Smart Infrastructure division. This acquisition integrated KACO’s advanced silicon carbide (SiC) inverter technology into Siemens' broader portfolio of building technology, electromobility, and energy storage solutions. As of 2026, the brand continues to lead in the clean energy market under the ultimate ownership of Siemens, maintaining its reputation for high-quality German engineering.
