Across the country's National Interconnected System, Brazil's 9GW-plus of wind power supplied 5,783 average MW (138.8GWh), enough electricity to power 27 million homes.
The new production high was the result of the country's southern sub-market witnessing record wind production. Wind projects in the south produced 1,302 average MW (31.2GWh) of wind power, beating the 1,289 average MW (30.9GWh) set on 8 June.
The windier northeast region of Brazil also set a new production record, two days earlier on 5 September. It produced 4,784 average MW (114.8GWh), the energy ministry said.
Wind is helping to plug a gap in northeast Brazil left by a dip in hydropower due to a lack of rain in recent years, the ministry added.
Brazil is targeting 24GW of installed wind capacity by 2024.
