When trying to set EssSystemSettings.MaximumSystemGridFeedIn with NODE RED to a Value greater than int32 (33400) you get an out of range exc (Number outside Range)
it changes with 32767 (valid) 32768 (invalid)
The node "VE Bus System", system "multiplus-II" chosen.
The measurement "Battery current" do not show positive charging current, only negative current pulled from batteries. While charging, msg.payload is strictly 0. I don't know if this is intentional, but it is in my view not logical. No big deal, I can calculate what I need from other input and output measurements of the multi, just wanted to report this if it is indeed a bug.
Love your work.
