A power conversion system for commercial and industrial storage has been developed by SolarBridge Technology, a U.S.-based manufacturer, so that buyers can keep their federal tax credits. The Golden Gate STC-P135, which is rated at 135 kW, is to be shown at RE+ 2026 in Las Vegas, and its volume production is to begin in Dallas in early 2027.

SolarBridge Technology Inc., a U.S.-based maker of power conversion systems (PCS), hybrid inverters and energy management software, is to show a new product at RE+ 2026 in Las Vegas, Nevada, United States, on 17-19 November. The Golden Gate STC-P135 is a 135 kW bidirectional PCS for commercial and industrial (C&I) storage, and its volume production is to begin at the company's new facility in Dallas, Texas, United States, in early 2027.
SolarBridge points to the One Big Beautiful Bill Act, under which a storage project relying on equipment from a foreign entity of concern (FEOC) can lose the federal Investment Tax Credit, worth 30% or more of its cost. The company has also cited a recent FCC rule, which bars new foreign-made inverters and PCS units that lack existing FCC approval. SolarBridge, for its part, plans to have an independent law firm certify its non-FEOC status and supply chain by early 2027.
The units have been kept small by design, as the company has said that smaller projects were left with limited options while manufacturers concentrated on systems above 1 MW. Integrators can build systems of up to about 1 MW from them, and the company's Integrated AC Cabin holds four units, or 540 kW. Battery voltages of 720 to 1,500 volts are accepted, both grid-tied and off-grid operation are possible, and the peak efficiency is 98.7%. Should one unit fail, it can be pulled and replaced while the others carry on.
We're not just assembling a product in Dallas. We're building a production line around state-of-the-art automated testing equipment. Every unit that leaves this building will have been tested at full power, and every one will help a Texas manufacturing workforce grow with this industry.
Larry Huang, Senior Director of Manufacturing and Quality Control at SolarBridge Technology
Production equipment is due to arrive in Dallas in November 2026. At full output, the plant is to turn out 1,000 to 1,500 units a month, and its first phase is expected to bring about 50 jobs. Several national storage companies will begin testing the sample units in December 2026, and a liquid-cooled 450 kW string PCS, the STU-P450, has been planned for the second quarter of 2027 for utility stations of up to 7.2 MW.
Moment Energy took a similar step in September, when it said that a Top 10 US law firm had verified its non-Prohibited Foreign Entity status and FEOC compliance, since a project that fails the rules can face clawbacks during a 10-year recapture period. In October, Energix Renewable Energies signed an MoU with LG Energy Solution for up to 4.5 GWh of BESS by 2028, and that framework includes potential U.S.-manufactured, FEOC-compliant systems.
