Jeff K reacted to Coulomb in Axpert MAX I 11kw 100v stickingThe display firmware supports it, the DSP firmware does not. Sadly, I don't have any 73.xx firmware that does.

500.12 was definitely a problem and Growatt themselves instructed me to revert to the previous version (500.11 as I recall) to stop the fan fail warnings.
As soon as I reverted, that nonsense stopped.

Try upgrading first to 500.09 and also update your comms and BMS firmware . if it still does not work, check your cable connections id they are all tide.
