After monitoring VRM since installing ESS I've noticed that my Bat and Charging voltage never reaches absorption voltages. My absorption volage is 57.6v, Float is 54.4v (AGM) as configured on the Multi. In ESS, SOC is 85% (Min and actual.) I also have two scheduled charges. One charge begins at the tail-end of usable PV late in the day, overlapping the last bit of sun (to capture some PV so as to limit some of the draw from the grid when charging.) This charge ends roughly 6 hrs later around 1:00 AM EST at which point I am inverting for 6 hrs, until the sun comes up. Both scheduled charges have SOC limit reached unchecked so that it stays in the charging cycle, intentionally, to keep the Multi from slipping back into inverting.
Other ESS settings that might be pertinent, Optimized Mode with Battery Life, DC-Coupled Feed-in with Limit 0W.
Even during the scheduled charges, mostly grid supplied, I never see more than the float voltage. Any thoughts as to what or why this is? @Alexandra perhaps you can comment as you are very knowledgeable on this area? :)
