I updated the settings for all devices via InsightLocal and the settings are sticking now. I think there was some sort of conflict. When I changed settings via the SCP, they would not be reflected in InsightLocal, but when I changed settings in InsightLocal the settings would instantly change on the SCP.
I think the source of the high DC voltage issue was something else, however. I discovered that all of the charge controllers were set to Flooded rather than Custom battery type (for LFP), and some of the charge controllers had equalization enabled. It was cloudy yesterday, so I have to wait until solar gets the batteries to 100%, hopefully today, to see if the high DC voltage issue comes back.
