Inverters: Fully SiC design takes the win
The jury of the pv magazine Awards 2025 once again faced a challenging comparison. Submissions spanned the full inverter spectrum, from microinverters for balcony systems to multi-megawatt central units for grid-scale storage. The diversity of technologies underlines how dynamic the inverter segment remains and how difficult it is to evaluate across this spectrum. Facing the challenge, the jury awarded first place to a product dedicated to the fast-growing grid-scale battery storage market – an offering that also aims to open opportunities in new market fields. Second place similarly went to a grid-scale design that reduces servicing costs in this segment.
Winner SMA Sunny Central Storage UP-S SMA’s new battery inverter platform comes in four power classes ranging from 2.7 MW to 4.6 MW. With an efficiency of 99.2%, it was one of the highest ratings in this year’s competition. A key innovation lies in the inverter’s use of silicon carbide (SiC) transistors across its entire …
