ESS suddenly started oscillating after 2 years of stable operation

Hello,

I reinstalled Venus 3.33 on the Cerbo GX. The following post appears to describe an identical problem, which is why I chose this version:

With version v3.33, my system is working as it did before.

It would be good if Victron could provide an explanation of how ESS operates between the different versions.

I will have to do without the new Venus interface.
