Hello,
I have two series BAT412201084 AGM 12V batteries with a solar system. Its data sheet lists the Absorption Voltage as 14.2v-14.6v.
Questions:
Q1 Should the BMS charged voltage parameter be set using the upper or lower of these values (i.e. 28.4 or 29.2v)?
Q2 Should the charged voltage be set 0.3v or 0.6v below Absorption Voltage (i.e. is the 0.3V in the case of a solar system per battery?).
The possible setting are:
CV = (2 x 14.2) - 0.3 = 28.1v
CV = (2 x 14.6) - 0.3 = 28.9v
CV = (2 x 14.2) - 0.6 = 27.8v
CV = (2 x 14.6) - 0.6 = 28.6v
Thank you.
