Hi, Sorry if this is a common question, I'm very new to Solar and trying to learn. I'm very impressed with my Victron gear but there is 1 problem.
I watched the Victron video explaining to change the BMV settings and have done so however the SOC detection still doesn't seem to be working...hope someone can offer some advice.
120Ah "Fusion" brand battery
110W Solar Panel
VenusOS on a Pi 3B+ with 2 x USB to VE Direct cables
The battery seems to be charging fine, I can see bulk then absorption then float phases. Unfortunately the SOC never gets reset at all, it just gradually declines until it's zero.
I haven't changed anything on the MPPT, it's by default at Factory default "Gel Victron deep discharge 2".
The BMV I have these settings:
Battery Capacity: 120Ah (I changed this)
Charged voltage: 13.5V (I changed this)
Tail Current: 4% (default)
Charged Detection time: 3m (default)
I set the charged voltage at 13.5V because I can't find the battery stat for this on the manufacturer's details so I looked at the average figure during absorption phase, 13.8. Based on this I set charged voltage at 13.5, 0.3 below absorption rate per video instructions here:
I guess I must have misunderstood something, can anyone help?
