Fronius inverter AC coupled runs throttled after firmware update

HI,

I have a 5kVA Quattro with a Fronius Primo 8.2 AC Coupled (5.5Kwp PV) and a Victron DC Coupled mppt 250/60 (3kwp PV).

It all worked well for more than 3 years until I updated the Victron to the latest firmware. The fronius runs throttled permanently now. I updated the fronius to the latest firmware chose MG50 and reloaded the ve config and ess assistant again but it still throttle the PV on the fronius. Fromius SA tech team logged into my system and confirmed everything is fine on the Fronius. They reffered a Victron expert and he logged in and all settings are correct.

Any advice would be appreciated.

kind regards
