Hey,
Im having a 12v 100ah lithium lifepo4 battery and a 100/20 MPPT device.
Im trying to set the MPPT controller to load my battery not to 100% but to 80% or 90%.
I know there is an absorption voltage, float voltage and in expert mode even more voltages (equalization and bulk voltage) that can be set to go from one loading phase to another. Unfortunately the manual is no help for me.
While loading most of the time the controller is in BULK mode, then goes over to ABSORBTION mode and when full it goes to FLOAT mode.
Could someone explain these voltages and how to set them to load only 90% of the battery? The absorption mode is not clear to me, the other seem more logical (but would be awesome if someone would explain them too).
Here's the datasheet for my battery
Current settings are:
Absorption voltage: 14.20V
Float voltage: 13.50V
Expert mode deactivated
Thanks in advance!
