Inverter manufacturer Fronius released an official information about State Code 107 appearing at Fronius Symo 10.0-3-M, 12.5-3-M, 15.0-3-M, 17.5-3-M and 20.0-3-M produced from May 2017 to 18 August 2017 (Serial numbers 28173818 to 18346124)
In case this Code is shown on inverter’s display, inverter cannot feed in anymore and needs to be re-started through an AC-reset. However, this is only short-term solution, Fronius strongly recommends updating the inverter with the latest firmware version.
