Hi All
Is it bad for Lithium batteries to be going in to bulk / absorption daily - when they probably don't need to ?
Situation is....
Thanks

As a precautionary measure, you could set all chargers to some lower voltages.
Such as: absorption 3.40V ... 3.45V (LiFePO4 cell voltages).
Float voltage should be about 3.35V even now.
Arhh.... I see... good idea.
Do you know if it is bad for the MPPTs to going in to bulk / absorption every day ?
I've got AGMs, not lithium, but with my MPPTs set to end absorb based on tail current, it doesn't seem to be an issue. It's usually no more than 5 minutes from the point where the MPPTs are making enough power to push the voltage up to the point where they hit absorb voltage, sense the low current and immediately drop to float, allowing the voltage to fall back to float voltage. So the batteries aren't getting held at higher voltage for very long every morning.
That said, it would be nice if DVCC had a way to send the MPPTs right to float if SOC = 100% and the multiplus is on shore power and currently in float.
