Onsemi and Sungrow partner on SiC tech for utility energy storage
Onsemi (Nasdaq: ON) announced that Sungrow has adopted onsemi's EliteSiC silicon carbide hybrid power module technology for its PowerTitan 3.0 energy storage platform, according to a company press release dated Oct. 14, 2026.
The integration improves inverter-level efficiency by 0.4% compared with the previous-generation platform. Onsemi's analysis states that this efficiency gain could save more than 475 MWh of energy annually in a 100 MW battery energy storage installation.
The PowerTitan 3.0 platform uses onsemi's high-density power integrated modules, optimized for three-level inverter architectures. The architecture supports power conversion units rated up to 450 kW and achieves peak efficiency exceeding 99.3%.

Sungrow estimates delivering 10 GWh of PowerTitan 3.0 across Europe in 2026. "PowerTitan 3.0 represents Sungrow's continued innovation in advanced energy storage system design," said Chen Peng, General Manager of Energy Storage Conversion Product Line at Sungrow Energy Storage Business Unit.
"At utility scale, even small improvements in power conversion efficiency can have a meaningful impact on battery energy storage system performance and total cost of ownership," said Sergio Fissore, Vice President and General Manager of the IPD Power Division at onsemi.
