About Sungrow
Sungrow Power Supply Co., Ltd. is a Hefei-based manufacturer of PV inverters and battery energy storage systems, active in China, Europe, the Americas, Australia, the Middle East and Southeast Asia. In BESS it acts as a system integrator: Sungrow designs the string PCS, EMS, thermal management and enclosures, while LFP cells come from third parties not identified on product pages or datasheets. The utility line is the PowerTitan family of liquid-cooled 20 ft AC blocks with PCS inside the container: PowerTitan 3.0 (6,904 kWh, 4 x 450 kVA SiC PCS, launched June 2025), PowerTitan 2.0 (5,015 kWh, 314 Ah cells, 2023) and the legacy PowerTitan 1.0 DC container (ST2752UX / ST2236UX) paired with SC-series central PCS. C&I products are the PowerStack 255CS (257 / 514 kWh, 125 kW), PowerStack 200CS (229 / 458 kWh, 110 kW, EU/APAC) and the modular PowerKeeper pack system (50–250 kWh). Datasheets are published per SKU, with US, EU and AU variants differing in grid standards, certifications and ratings. Not published: cell supplier, cycle-life data and test conditions, warranty terms, and system RTE for most SKUs (only press releases quote RTE); the 12.5 MWh '30 ft Plus' PowerTitan 3.0 has no public datasheet yet.
