Use two 5 watt solar panels and a continuous duty isolator relay. It can't
get any simpler than that.

Okay sounds good. The isolator would connect to what other than the
two batteries? And it's purpose would be to keep anything on the boat
from pulling from the aux right? Also, would 5watts overcharge the
batteries and require a controller?

Yes, the batteries would have no load while sitting, but I'm recalling
those two week trips and my car not starting when I got back.

Thanks!
