Could more efficient battery storage systems meaningfully reduce energy costs for your household?
Sungrow has integrated onsemi silicon-carbide (SiC) power modules into its PowerTitan 3.0 energy storage platform. This design update raises peak inverter-level efficiency to 99.3%, marking a 0.4% increase over previous generations.
Why it matters
Higher conversion efficiency directly improves the economics of utility-scale storage by reducing energy waste. In a 100-MW system, this 0.4% efficiency gain translates to an additional 475 MWh of electricity delivered to the grid annually.
The PowerTitan 3.0 supports power-conversion units rated up to 450 kW. The system achieves its 99.3% efficiency rating using three-level inverter topologies that combine SiC MOSFETs for high-frequency switching with traditional silicon power devices.
The players
Sungrow
A global manufacturer specializing in solar inverters and utility-scale energy storage systems for grid-tied applications.
onsemi
A semiconductor company focusing on power-management integrated circuits, specifically SiC technology for industrial and automotive efficiency.
The details
The platform utilizes SiC MOSFETs—semiconductor switches that operate at higher frequencies and temperatures than standard silicon—to minimize switching losses. By pairing these with silicon power devices in a three-level inverter configuration, the system reduces the voltage stress on individual components. This architecture not only boosts conversion efficiency but also enhances thermal management and overload capability for demanding grid conditions.

The Tech Race
The adoption of silicon-carbide components places Sungrow in direct competition with other energy storage firms attempting to lower levelized costs through semiconductor upgrades. This shift accelerates the move away from traditional silicon-only power modules in utility-scale deployments.
Utility-scale operators can now specify the PowerTitan 3.0 to increase energy availability in 450 kW power-conversion increments. The 0.4% efficiency increase provides a quantifiable reduction in energy loss, though adopters must weigh the performance benefits against the integration costs.
The takeaway
This incremental efficiency gain illustrates how component-level semiconductor choices can significantly shift the total energy output of large-scale infrastructure. Stakeholders should monitor whether these SiC-based architectures become the new standard for 450 kW class units in 2027 installations.
