Hello,
I'm in the process of upgrading my equipment to Victron but I'm having a few issues with the solar charger voltage.
Currently I have
4x100AH flooded batteries (will be upgraded later)
120w solar panel (will be upgraded later)
Victron 3000w/12/50 inverter
Victron BMV-712 battery monitor
Victron 100/50 Smart solar
On random clear sunny days the solar voltage will drop to 12v but the following day it'll be back up to 21v. It isn't a weather issue nor panel as I've metered the solar voltage from the panel and it registers 21v but when plugged into the solar charger it reports 12v?
Here is photos showing the problem

Any ideas?
