Thank you for the response. Today with those screenshots I am out at Anchor, later in the day we will have enough sun to reach absorption.
Yesterday and for three days before we were using the SHore power, and the voltage was in the range you specify and the BMS said it was balancing, but it never achieved balanced status. Despite 3 days of 8h sessions of absoprtion charge.
OK, I dont know why, but it looks like a bug, but I reset the SoC to 100% using victron connect, and then immediately the Lynx BMS reports the battery bank as Balanced.
