Your system is almost equal with mine, except I have 3200 watts up on the roof.
They're fixed, but they're set up in such a fashion that they don't get 100% focused sun all day, but someone's always getting good sun.
I hate wind generators, yeah yeah yeah, they make quiet ones, but fuck that shit.
The litmus test for a wind generator.
Is the wind a CONSTANT NUISANCE?
If you answered yes, then wind might be a good answer.
If not, it's hardly worth the extra cost and set up.
Yeah, there's times when the sun's not out, and another source of power would be good, but if the wind ain't blowin, it won't do any good.
But here's my thing.
I know a few folks that have them, and they're noisy as fuck.
They chop and whirr and speed up and slow down, and to me they totally screw up my peace and quiet.
I'd spend the extra money on more batteries.
Ya can never have too much battery!
You probably won't need it all, but you never know, you might end up in that cabin for more than a week at time with rate things are going.
Anyways back to your question, almost.
We have similar sized banks, although mine are lead acid forklift batteries.
I have almost all the amenities anyone else would have in their home, sans central heat and AC.
Stove, water heater, fridge and small room heater are on propane.
Everything else is electric and runs off the solar.
We have computers, and fans, and toasters, and washing machine. The wife irons, I have power tools, saws la la la, you get it.
I use them just about anytime I like.
I also have a small 7 cubic foot electric freezer that's on a timer. It runs all day, and shuts off at night.
My point is, you're probably aren't going to use near as much power as I do by any stretch, especially only being there a handful of days a month.
The other thing is if no one's making or selling propane, you don't have a fridge, and unless someone takes the sun away....
After this last go a round with propane fridges, I think I'm done.
This one was about $2000 plus freight.
It's made by the Amish.
When I bought it, I somehow thought this was going to be a done deal, and that it would somehow last longer or be better than the others.
Unforunately, it's locked up.
Fortunately, it still under warranty,and they're going to replace the cooling unit.
Unfortunately, it has to be shipped from Illinois.
Fortunately, they're going to pay for it all.
Unfortunately, I have to do all the work myself.
There is one very slight possibility that they might just ship a new fridge.
I'll know tomorrow.
So at this point, I say screw propane cooling.
The problem is this: they have to put an anti rusting compound in with the ammonia, and that compound crystalizes over time, blocking the flow of coolant.
Screw it, I'll fix this one or whatever, but after that, I'll add another battery if I have to, and for my money, I'm going electric.
tl;dr. Go with electric!
Here's my panels set up, although I'm still not sure why my roof came out pink. (stupid drone)
It's white. Wow, that was like 8 months ago.
