Grid-forming inverters: SMA and M.O.E. put a new verification method i...

02.10.2026 | Itzehoe (renewablepress) - The manufacturer SMA has reached an important milestone in the development of grid-forming inverters. Following extensive testing, simulations, and model validations, the M.O.E. certification body has issued a prototype confirmation for grid-forming capabilities based on VDE FNN Guideline 2.1 for the Sunny Central Storage UP-S 4600 inverter with “Full Boost” current boost. This is the first prototype confirmation of its kind in the industry. The project took a newly introduced technical requirement through the complete practical verification process: from the manufacturer’s development phase, through testin... more...
