Siemens to set up 800-MW solar inverter production line in Wisconsin

Siemens Corporation, a US-based arm of German conglomerate Siemens AG, will set up a production line to produce 800 MW of solar string inverters annually in Wisconsin, it said on Tuesday.

The photovoltaic (PV) inverters will be made in Kenosha and will be designed to address the needs of the US market as demand is expected to grow thanks to the tax credits available under the Inflation Reduction Act (IRA). The products will be sold to community and utility-scale solar developers and infrastructure providers.

Specifically, Siemens will house the manufacturing line for 5,200 BPTL3 string inverters at the Kenosha facility of its local manufacturing partner Sanmina. The inverters will have capacities of between 125 kW and 155 kW and will be suitable for 1,000-V DC or 1,500-V DC solar array input. Production is due to be launched early next year and will scale up until the 800 MW target capacity is reached.

Capacity reservations for volume commitments for 2024 have already begun.

“[..] Siemens is well positioned to address supply challenges our country is facing as we work to localize production for green and renewable infrastructure,” said Brian Dula, vice president of the Electrification and Automation business at Siemens Smart Infrastructure USA.
