SMA ShadeFix is our software-based shade management system. Commonly this feature is used in systems with light to medium shading. Your energy yield is optimized without adding any further components to the system or PV modules. SMA ShadeFix is already integrated into SMA SUNNY BOY and SUNNY TRIPOWER inverters and activated automatically during commissioning. There are no additional costs because SMA ShadeFix is an integral part of the operation management of SMA SUNNY BOY and SUNNY TRIPOWER inverters.
