NeoVolta establishes U.S.-based BESS manufacturing in new joint venture
San Diego-based energy technology firm NeoVolta announced the launch of a new joint venture with LONGi Green Energy and PotisEdge Jan. 14, establishing domestic BESS production in the U.S.
Described by company representatives as “transformational,” the joint venture will allow NeoVolta to serve both the utility-scale and commercial and industrial (C&I) solar markets as a manufacturer. Known as NeoVolta Power, LLC, the firm will emanate from a manufacturing platform for battery systems in Pendergrass, Georgia and will support 2 GWh of initial annual production capacity starting in mid-2026.
“This transformative joint venture with PotisEdge and LONGi represents a major step forward for NeoVolta, positioning us as a vertically integrated leader in the fast-growing energy storage sector,” says NeoVolta CEO Ardes Johnson. “By launching domestic BESS manufacturing, we’re directly addressing surging demand in utility-scale and C&I markets, enabling scalable, reliable solutions for grid stability, peak load management, and high-growth applications.”
Officials added that the facility’s production numbers are scalable up to 8 GWh per year, should the need arise. The plant will employ approximately 89 production personnel for initial capacity, and “will initially focus on prismatic-cell battery pack assembly and DC container integration.”
The platform’s initial production capacity represents about $400 million in annual revenue potential at full utilization, the company says. Reports from Wood Mackenzie expect the battery energy storage market to expand to $45 billion by 2030, but actual results for the joint venture may vary.
Corporate changes and inclusions
Production at the plant will be weighted towards utility-scale BESS projects, with C&I making up and increasing share of the product catalogue as demand and need arise. This shift in market focus marks the culmination of a business transformation for NeoVolta, the company says.
In the evolving solar market of 2026, the manufacturing platform is built to support multiple sets of product formats and system configurations, representatives say.
NeoVolta has a 60% controlling stake in the recently established joint venture, with LONGi and PotisEdge each holding a 20% stake in the new LLC. LONGi will contribute “deep expertise in large-scale battery manufacturing,” the companies say, with installation, commissioning, and production ramp support on the Chinese firm’s to-do list for the project.
“LONGi’s strategic expansion into energy storage reflects our commitment to delivering integrated, scalable clean-energy solutions,” said Eric Luo, group vice president and president of North America at LONGi Green Energy. “By aligning PotisEdge’s technology leadership with NeoVolta’s U.S. market expertise, this joint venture brings together complementary strengths to serve the next phase of growth in renewable energy infrastructure.”
LONGi got its feet wet in the energy storage space with the acquisition of PotisEdge late last year, folding it into one of the world’s largest renewable energy companies.
“PotisEdge is proud to partner with NeoVolta in building a U.S. battery manufacturing platform designed for scale and long-term growth,” said Minjie Shi, founder and chief technology officer of PotisEdge. “As a minority owner, we are contributing our manufacturing experience, systems, and technical capabilities to support efficient execution and a successful production ramp for utility-scale and C&I energy storage solutions.”
