Hi everyone, I wanted to know if any of you could better explain some of the behaviors of my 12v system.
I have 4 PV panels in series for 80 volts of VOC and 9 amps, an epever 6415AN and 4 AGM in parallel 12 v 440 amps total .
Use as boost parameters 14.50 volts ( no equalization ) , a float at 13.70 volts , a boost duration of 180 mn and a coefficient of -2 mv .
Normally in the evening at the cut off I find myself with 12.77 volts, in short, the batteries are almost charged. I noticed that under normal conditions, around 12:00 Pm the voltage is already at 14.50 and a little more and then around 15:30 (if the day is clear) the current drops and then goes into a float, keeping at a voltage of 13.30 - 13.60, in short, oscillating. Today I changed the float to the default one that provides 13.80 volts and I noticed that even if I use a load of about 100 w, with this maximum bulk voltage of 13.80 the batteries begin to absorb, in short, to give an example: if in the afternoon I have the load of 100 watts with a stable float of 13.80, I see that the power of the panels is also brought to 300 watts, as if the batteries still require some current. Is it possible that this epever float is a pseudo float as some users have written on the internet? I know that when the batteries go into float it should absorb little current, in my case 440 / 4 110 amp batteries, they should absorb a maximum of 2 amps for one.
