I have yet to see any FLA battery that can go 4-5 months without service.
Typically a FLA needs an increased voltage to attain the same full charge
rating at low temps, but you still require watering. I have clients with
shut down houses and no load situations, we back off the Absorb set point
volt
I agree with Todd and Bob, leave the PV solar on, EQ off.
I also instruct my customers to reduce the absorb timer to 0.1 hours. Since the
battery is staying full, there is no need to spend time above cell gassing
point which will increase water loss.

Everything mentioned so far works well however, if you're using a charge
controller with an auto equalize function.
Turn it off!
I had a friend who has left his system over the winter for years with no issues
and he shut his inverters off one year got back to the batteries being boiled
dry

i built a system for a friend's seasonal (summer) off-grid residence in alaska.
my instructions were simple:
leave the pv input & cc output breakers "on" and the load breakers (inverter,
dc sunfrost etc) "off".
there was never a problem with winter freezing (even at -40f) until one year

AGM - sealed type batteries are perfect for non- maintenance individuals and
prolonged non usage periods as long as the bank does get a semi regular
recharge.

I do systems like this every year. (-45F winter temps). Use quick connects and
train the customer on the batteries and their maintenance. Find bats with
freeze points that match your area. I typically mount the modules at 90degree
so snow never covers the array/module.

Hey Wrenchers,
A friend wants a very small battery set up at hunting cabin (like under
1kW). It will only be used in the warmer months. I'm wondering what you all
recommend for the batteries over the winter. I assume the ideal situation
would be that they would be disconnected and brought somewher
Why size is the generator?
How much load?

That is what we are doing as a temporary fix.
According to outback the charger should stay off if it's set that way. It's
unclear why it's not doing it.
Actually opticsRE will allow full programming.
No phone app ( darn) but computer yes.
