Fronius Releases Symo GEN24 Plus Solar Inverter

Fronius International has launched the Symo GEN24 Plus solar inverter. Its Multi-flow technology makes it suitable for a wide range of applications supporting energy self-sufficiency.

fronius“SiC modules can be used to build very energy-efficient, robust, and reliable inverters,” said Andreas Luger, Head of R&D Power Electronics from the Solar Energy Business Unitat Fronius. “This technology enables significant increase in switching frequency. Compared to the previous generation, the functionality is significantly improved, while its size remains comparable. Each device now also has an output for a secure power supply, and backup power, in addition to the standard connection options for a hybrid inverter.”

“To maximize the advantages of SiC, engineers from Fronius and Infineon have jointly optimized the layout and chip assembly of the modules,” said Peter Wawer, Division President Industrial Power Control at Infineon. “Ultimately, the close communication between the development teams enabled system advantages that correspond to customer needs. Based on our tried and tested Easy module, the inverter’s booster stages now use 1200 V CoolSiC MOSFETs in combination with CoolSiC diodes. This full-SiC solution thus ensures maximum efficiency.”

All this thanks to silicon carbide (SiC) from Infineon Technologies with an efficiency of over 98 percent. In combination with the high voltage storage from BYD, the Symo GEN24 Plus achieved a record value in the System Performance Index (SPI) of 94 percent in the 10 kW class. It was the only one in this combination to achieve Class A energy efficiency.

The combination of SiC MOSFET modules in the booster and battery input with hybrid modules in the inverter stage ensures the best possible ratio of efficiency and cost. As Infineon’s SiC power semiconductors have a high power density, the Symo GEN24 Plus from Fronius offers many functions such as backup power, storage connection, multi-MPP tracker, and energy management.
