I am not able to set any numbers in "Grid setpoint’ with VRM (negative = feed-in energy to the grid, posive = take energy from the grid). As soon as I return to the ESS screen the set value is set to 0 and the Limit feed-in on the feed-in screen is set to ON.
I have a Cerbo-S (Venus v.3.55) and 3x (3-phase) MultiPlus 70/5000 (firmware v.556). No Dynamic ESS. (set to off).
Is this a Cerbo problem or MP a problem (or a VRM problem?). Anyone with the same issue?
does your grid standard permit export? and are you able to set this locally?
