EPC Power Inverter Manufacturing, 27 GW Capacity Expansion, Generac Partnership, and 2 Key Product Launches (2024 to 2026)

US Inverter Manufacturing Capacity, EPC Power Triples Output to 27 GW

Domestic manufacturing of power conversion systems has become a strategic imperative, driven by the convergence of AI-driven electricity demand and persistent global supply chain risks. EPC Power’s recent expansion is a direct response to this market shift, adding 27 GW of annual inverter production capacity in the U.S. to specifically serve data center and grid infrastructure clients who now prioritize supply chain security alongside technological performance. This move signals a fundamental change in procurement strategy, where onshoring production is no longer just a political objective but a critical component of project execution and risk mitigation for energy infrastructure.

• Between 2021 and 2024, the primary focus for inverter supply was managing component shortages and logistics hurdles from Asia to support the build-out of utility-scale solar and storage projects. The technology was often viewed as a commodity, with procurement decisions heavily weighted toward cost.
• From 2025 to today, the narrative has pivoted dramatically. The explosive growth of AI data centers, whose power demand is projected to reach 134.4 GW by 2028, has created an urgent need for high-performance, grid-forming inverters. Major tech operators like Google and Meta are exploring diverse energy strategies, making the power stack a critical enabler.
• EPC Power’s inauguration of a new 167, 000-square-foot facility in Fountain Inn, South Carolina, in July 2026 directly addresses this new reality. This plant nearly triples the company’s manufacturing footprint and is designed to produce the M-series and MRACK inverters, which are essential for stabilizing power for high-intensity AI workloads.
• The expansion provides customers a hedge against geopolitical tensions and tariff volatility, while also allowing them to capitalize on incentives like the 10% domestic content bonus tax credit under the Inflation Reduction Act (IRA).

$4 M+ Raised, EPC Power Finances US Factory Expansion

EPC Power secured the necessary capital to fund its aggressive U.S. manufacturing expansion through strategic equity financing from private investment firms. This funding was not for speculative research but was allocated directly to the capital expenditures for the new South Carolina facility, demonstrating investor confidence in the thesis that domestic, high-performance power electronics are critical to enabling the AI and energy transition infrastructure boom. The investment de-risks the company’s expansion and ensures it has the resources to scale production to meet secured and anticipated demand.

• In December 2025, it was reported that EPC Power had raised at least $4 million in equity financing to support its growth and manufacturing initiatives. This capital injection was critical for funding the development of the new plant.
• The financing round included participation from prominent investors such as Cleanhill Partners, Goldman Sachs Asset Management, Rhea Capital Management, and 13 Capital, indicating strong institutional backing for the company’s domestic manufacturing strategy.
• The primary use of these funds was the construction and operational launch of the Fountain Inn, South Carolina plant, which officially opened in July 2026. This facility represents the core of the company’s strategy to capture the high-value data center market.
