I have onnected 6 panels of 275W with two individual (3 panels in both) MPPT 150/85 Tr solar charger connected into battery bank of 1200Ah via LYNX IN bushbar. I have a MultiplusCompact inverter charger 12V 3000KVA for 230V. I have bluetooth smartdongle and BMV-700 for adjusting the chargers and Multiplus with my laptop and iPAD. I have a battery bank of PzS 1200 Ah/12V semi traction battery bank consisting of six pieces of 2V/1200Ah batteries.
I have an HONDA 2,2kW generator for Multiplus charger.
I performed manual equalization when it was a sunny day and the battery bank was in float mode. I put "ON" the process in one of my two chargers. Why did the equalization voltage not rise to its set value of 16.9V but remained at 15.7V? Why did the equalization process last only one hour even though the maximum time in the settings is 4 hours? Attached are the mppt controller values set with the victron connect app.
