solar charger questions
Hello, I have a couple questions. I have 2 6v 225 interstate batteries with a 100 watt zamp solar panel mounted on the roof of my 2015 Nash 25c. I also have a eco 100 watt portable unit with its...

.....until the batteries were at 14.5-.7 and then there was still 1-1.5 amps of chargeCan you explain this more fully? You are stating a voltage and a level of current, two dissimilar things.
The charge controller may be charging the batteries at 14.7 Volts and you may have 1.5 Amp Hours of capacity to fill but that isn't clear from your post.
After the batteries have rested with no charge and no load what is the voltage? The Victron should display that in the early AM before sun hits the panels.
Theoretically, the solar charge controller will charge until the batteries will not accept any current from the solar system. There is always a small amount of self-discharge (along with any parasitic loads) so that state of charge is fleeting.
I have a programmable, temp compensated controller and it is usually back at float level very early in the morning when in storage. It will cycle through the bulk and absorption charge levels quickly before going into float.
More focused advice can be given if you share which controller you have.
