Hey Im having trouble with my smart BMV 712 not sowing the correct SOC when my MPPT charge controller is at absorb.
I have tried manually syncing it to 100% when I reach absorb on the MPPT. This seems to work for a couple of weeks but then goes back to about 82% give or take 1%
Im pretty sure I have things wired up correctly.
16 x Battle born batteries wired to 48 Volts
Please see photos and let me know if you have any ideas on this.
Thank you so much, any help would be hugely appreciated.
If you want accurate voltage readings, change the battery in your multimeter. Re low battery warning on multimeter display.
Have a look at the BMV Youtube tutorial.
Follow Battle Born's BMV set up guide.
Follow Battle Born's Manual and Installation Guide for advice on charging voltages, and advice on series / parallel battery banks.
Change your charged voltage to say 56, or just above float voltage. try 56 first
