Siemens to begin manufacturing solar inverters in Wisconsin

Aug. 18, 2023
The string inverters will range from 125 to 155 kW and will be manufactured with a California Energy Commission (CEC) efficiency of 99%.

Siemens has announced plans to begin manufacturing photovoltaic (PV) string inverters in Kenosha, Wisconsin. The string inverters will range from 125 to 155 kW and will be manufactured with a California Energy Commission (CEC) efficiency of 99%. According to the company, the inverters are designed for 1000- or 1500-Volt DC solar array input, as well be being compatible with either decentralized or ‘virtual central' design architectures. The facility, owned and operated by Sanmina, will produce utility-scale solar components. Production at the new plant will begin in 2024 and the expected capacity will be 5,200 BPTL3 string inverters (800MW) per year.

In a recent quote, Brian Dula, Vice President of the Electrification and Automation business at Siemens Smart Infrastructure USA, said, “According to the Solar Energy Industries Association (SEIA), the total number of installed U.S. solar fleets is expected to grow fivefold from 2022 to 2033, and with tax credits now available due to the Inflation Reduction Act, that demand will only get stronger. Working with Sanmina to establish this new production line, Siemens is well positioned to address supply challenges our country is facing as we work to localize production for green and renewable infrastructure.”
