I have a 305w solar panel connected to victron 100/20 to two 12v 100ah batteries.
On day 1 and 2 of all powered up I was getting 100-180wat showing on the victron connect app and can see batteries charging. Today on a very hot sunny day the app is only showing solar panels at 22-35w which cannot be right. All wiring and breakers are ok, and it appears im still charging the batteries as I can see 13.8v showing.
