Diapered Horse Trots Up...
A lot depends on what the charge controller is capable of or more importantly what it isn't capable of.
Myself I like BFL's answer.
Spring arrives. You drive all the way up there -ooooooops ---- happens. The panel got covered with three feet of snow. Oops, something, a load turned on when it shouldn't have. Oops, the controller got a sudden case of PMS.
You find all this out not in your driveway but way the hell and gone back in the sticks. Where does it leave you. Up el creeko is where.
I like to weigh decisions like this using the "Risk Benefit" ratio. IMHO the teeter-totter with the take-them-home side is jammed to the ground.
