Keeping The Lights On With Wolfspeed SiC

EPC Power, a leader in utility-scale power conversion, has partnered with Wolfspeed to launch the “M” inverter, an innovative modular solution designed to revolutionize energy storage. Built with Wolfspeed’s 2300 V silicon carbide WolfPACK™ power module, the “M” inverter offers superior efficiency, power density, and reliability compared to traditional central inverters.

This modular string-style inverter combines the flexibility of smaller inverters used in residential solar systems with the scale necessary for utility-level energy storage. The modular approach simplifies installation, reduces maintenance, and improves system uptime by minimizing points of failure. With fewer passive components, the inverter offers a wider operating range for both AC and DC voltages and is optimized for seamless deployment across multiple energy storage sites.

By shifting from a complex three-level to a simpler two-level power conversion system, EPC dramatically reduced system size, cost, and development time. The “M” inverter bridges the gap between two architectures, delivering reliable grid-tied energy storage for LEO/MEO/GEO satellite systems, renewable energy storage, and other power-intensive applications.

Wolfspeed’s silicon carbide technology also extends the inverter’s lifespan, thanks to enhanced resistance against cosmic ray failures, resulting in lower maintenance costs and greater reliability over time. Together, EPC and Wolfspeed aim to drive global deployment of sustainable, scalable energy storage solutions, ensuring a more efficient and resilient power grid.
