SolarBridge launches 135 kW PCS for C&I storage
SolarBridge Technology, a Delaware-incorporated company founded in 2025 and headquartered in Dallas, has introduced the Golden Gate STC-P135, a 135 kW bidirectional power conversion system (PCS) aimed at commercial and industrial battery storage. The unit will be shown at RE+ 2026 in Las Vegas, with commercial production planned at the company's Texas assembly facility in early 2027.
Modular design and capacity
The STC-P135 is built around a modular architecture that lets system integrators scale multiple units to roughly 1 MW. SolarBridge also offers an Integrated AC Cabin that can house up to four units, providing 540 kW of aggregated capacity. The company says the modular approach allows individual unit swaps during maintenance without a full site shutdown.
Key specifications
- Rated AC power output: 135 kW
- Maximum AC apparent power: 148.5 kVA
- Maximum efficiency: 98.7%
- Maximum DC voltage: 1500 V
- Maximum DC current: 206 A
- Grid-connected configuration: three-phase, three-wire at 480 Vac when DC bus voltage is between 720 Vdc and 820 Vdc
- Supports both grid-tied and off-grid operation
- Full power output maintained at ambient temperatures up to 45°C
Software and compliance
The hardware can be paired with SolarBridge's proprietary, AI-powered energy management system, which stores customer data on domestic servers and supports demand charge management, time-of-use arbitrage, solar self-consumption, and backup power protocols. The company states that meeting FEOC and FCC requirements is central to its strategy, and it plans to have its non-FEOC supply chain independently certified by a third-party law firm by early 2027 while completing FCC equipment authorization.
Manufacturing timeline
Manufacturing equipment is scheduled for installation at the Dallas facility in November 2026, with local assembly, functional testing, and software loading beginning in the first quarter of 2027. The facility is expected to employ about 50 workers initially, with a targeted monthly output of 1,000 to 1,500 units, representing up to 2.5 GW of annual production capacity. Every unit will undergo full-power operational testing before shipment. Sample units are slated for field testing with select energy storage companies in December 2026.
Future product
SolarBridge plans to expand its lineup in the second quarter of 2027 with the STU-P450, a liquid-cooled 450 kW string PCS designed to anchor turnkey utility-scale block stations up to 7.2 MW, coinciding with a Phase II manufacturing expansion near Dallas.
Pricing, warranty terms, and final availability dates for the STC-P135 were not disclosed in the announcement.
