Siemens to begin manufacturing solar inverters in U.S.

21 August 2023

Siemens has made a significant announcement in sync with President Biden's trip to Wisconsin, revealing plans to commence the production of photovoltaic (PV) string inverters in Kenosha, Wisconsin. This move signifies Siemens' commitment to manufacturing utility-scale solar components tailored for the U.S. market. The manufacturing facility in Kenosha, operated by the longstanding partner Sanmina, aims to address the rising demand for locally produced essential components for photovoltaic projects. This effort aligns with enabling customers to fully capitalize on solar tax incentives and domestic content rewards.

Governor Tony Evers expressed enthusiasm, stating, "The essence of manufacturing runs deep in Wisconsin's veins. Siemens' decision to manufacture these environmentally friendly components in Kenosha not only aligns with this heritage but also contributes to our journey towards achieving 100% carbon-free electricity by 2050."

The Kenosha facility is a strategic addition to Siemens' expanding U.S. operations, underlining the company's robust manufacturing presence in its largest market. With an investment of $3 billion over four years to bolster U.S. manufacturing and strategic initiatives, Siemens has firmly established itself in the American landscape.

Senator Tammy Baldwin, emphasizing the importance of local support, remarked, "I championed the inclusion of strong Made in America provisions in the Inflation Reduction Act because our efforts to nurture a clean energy economy should uplift Wisconsin's workforce, businesses, and economy."

Brian Dula, Vice President of Siemens Smart Infrastructure USA, acknowledged the surging demand in the solar industry and its alignment with tax credits, stating, "Siemens is strategically positioned to address the supply challenges we face in localizing production for green and renewable infrastructure."

The production at the Kenosha facility is anticipated to kick off in early 2024, with the capacity to manufacture 5,200 BPTL3 string inverters (800MW) annually. These inverters, designed for 1000- or 1500-Volt DC solar arrays, boast an impressive California Energy Commission (CEC) efficiency of 99%, catering to both decentralized and 'virtual central' design architectures.

Ruth Gratzke, President of Siemens Smart Infrastructure USA, highlighted the company's commitment to sustainable practices, remarking, "Our investments in communities like Kenosha and our contribution to renewable infrastructure will play a pivotal role as we work towards achieving our net-zero objectives as a nation."

The initial phase of operations at the facility will generate up to a dozen jobs, with plans for further expansion both at the facility and within the regional supply chain.

Summit Ridge Energy, the largest commercial solar company in the U.S., extended congratulations to Siemens for their decision to manufacture inverters domestically. This move aligns with Summit Ridge Energy's goal of utilizing American-made technology, strengthening the domestic manufacturing sector, and creating employment opportunities.

The Kenosha production facility joins a network of Siemens manufacturing centers across the U.S., reinforcing its commitment to supporting key industries, including solar, semiconductor, battery manufacturing, and data centers.
