High-efficiency solar inverter systems and manufacturing solutions from Germany's leading industrial technology company
Siemens stands as a global leader in renewable energy infrastructure, leveraging over 175 years of German engineering excellence to deliver cutting-edge solar power solutions. While the company doesn't manufacture traditional solar panels, Siemens produces industry-leading photovoltaic string inverters in Kenosha, Wisconsin, where the company manufactures utility-scale solar components specifically designed to serve the U.S. market. Their comprehensive portfolio covers the entire solar value chain, from advanced automation systems to grid integration technologies.
The facility is projected to scale up to a capacity of 5,200 BPTL3 string inverters (800MW) per year, positioning Siemens as a key player in America's clean energy transition. With domestic manufacturing capabilities and German precision engineering, Siemens solar equipment manufacturing represents the future of sustainable energy infrastructure.
The string inverters range from 125 to 155 kW and are manufactured with a California Energy Commission efficiency of 99%. These high-performance units convert DC electricity generated by solar panels into usable AC current for utility-scale applications. The inverters are designed for 1000- or 1500-Volt DC solar array input and can be utilized for either decentralized or 'virtual central' design architectures.
The BPTL3 series represents Siemens' commitment to maximizing solar plant efficiency and reliability through cutting-edge inverter technology. Each unit undergoes rigorous quality control processes aligned with California Energy Commission standards, ensuring optimal performance in diverse operating conditions.
Beyond inverters, Siemens provides comprehensive solar monitoring systems and utility scale solar systems integration. Their smart infrastructure solutions enable real-time performance tracking, predictive maintenance, and seamless grid connectivity for large-scale installations.

Siemens solar power solutions excel in large-scale commercial installations, providing reliable grid-tied systems for energy producers nationwide. The company's inverter technology supports projects ranging from community solar gardens to multi-gigawatt utility installations.
Manufacturing facilities benefit from Siemens' integrated approach, combining solar generation with existing industrial automation systems. This synergy enables optimized energy management and enhanced operational efficiency.
According to the Solar Energy Industries Association (SEIA), the total number of installed U.S. solar fleets is expected to grow fivefold from 2024 to 2033, with tax credits from the Inflation Reduction Act strengthening demand. The Kenosha facility helps customers take advantage of the full value of solar tax credits and domestic content incentives.
Domestic manufacturing provides significant cost advantages through reduced tariff exposure and shortened supply chains. Projects utilizing Siemens equipment qualify for enhanced federal tax credits under the Inflation Reduction Act's domestic content provisions.
"As the largest commercial solar company in the country, Summit Ridge Energy congratulates Siemens—our long-term partner—on their decision to manufacture inverters in the U.S. which supports our efforts to provide affordable energy to American communities,"
— Raj Soi, Executive Vice President of Operations at Summit Ridge Energy
"I work in the solar industry and have not seen any Siemens products before. As a life long electrician I have used a lot of Siemens products. They make quality products and it is good to see them in the solar game,"
— Industry Professional
Siemens specializes in solar inverters and manufacturing equipment rather than photovoltaic panels themselves. Our BPTL3 string inverters convert DC power from solar panels into usable AC electricity.
Domestic manufacturing in Wisconsin eliminates tariffs and reduces shipping costs. Customers also benefit from enhanced federal tax credits for using American-made components.
Our inverters are compatible with most major solar panel brands and support both 1000V and 1500V DC input configurations for maximum flexibility.
Siemens provides comprehensive warranty coverage aligned with industry standards, backed by our global service network and local technical support teams.
