I have a battery system shown in the picture, 6 parallel branches of 4 batteries connected in series. The first 3 consist of old batteries which are 2 years old, the fourth branch consists of 1.5-year batteries, and the last two branches are made up of new batteries. Each branch contains a battery balancers.
Can someone explain how batteries will work in this system if the charge/discharge cycle is 1 day? How batteries are charging (do they get full capacity)? What should I expect? Please give your recommendations. Thank you in advance for your answers.
PS I hope each answer will contain facts, because I already browsed the Internet, and got very confused. Everyone says the opposite things.
In the diagram above you can see the battery voltage and current.
Equipment that I use is Victron Quattro 10KVA, Victron smart MPPT 100A, Fronius symo 5 kW, diesel generator 7,5 kW. 24 PV panels 270W connected to Victron smart MPPT and 24 PV panels 265 W connected to Fronius symo.
This is a fully autonomous system not connected to the grid.
