Assuming the OP shuts off the electrical loads when he leaves, keeping the batteries up while he's gone is pretty much a non-issue. Even if the output is down by 90% due to overcast/snow cover, it should be fine.
The batteries will hold a reasonable charge by themselves for several weeks assuming there is absolutely no load (I would disconnect the batteries when I left). A couple of hours on a generator and charger would bring them up to snuff !
I would not want to leave them for more than 1-2 months.
