I just tried setting the amps limit to -1 in the DVCC.
Each time the setting will not save so I can put ESS in to #3, I tried it on a few other cerbos and was still the same.
If you mean the setting “Limit charge current” then a setting of -1 is meaningless as you can not have negative charge current. The field is probably limited to 0.
It would be nice to have that back as I do use it that’s all and it puts ESS in to state 3.
0 amps puts the inverters to 53hz which is painful for some machines motors and they can trip out
