20W solar...need controller?
I have acquired a 20W solar panel that shows 20vdc when not connected to anything (in full sun). When hooked up to a 12v battery, I have seen it as high as 17vdc. I'm wondering if I can get away wit...

Trojan on AGM Float:
"applications where batteries are infrequently used, it is desirable to compensate for
self-discharge by keeping a low charging voltage on the batteries. This is called the float voltage.
Avoid using continuous float charging on VRLA batteries that are charged more than once/month."
Seems they prefer you disconnect and let them sit instead of getting the wrong float voltage? AGMs do sit without significant self discharge for longer than a month.
RV "disconnect switch" does not usually disconnect everything (LP alarm, radio settings, etc, stay on) so watch for that.
