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.
I always recommend removal. I've thought about temp controlled incandescent lamp with a timer in a battery box for really cold nights.... Haven't got around to working through that design. I'm interested in the real seasoned off-grid installers thoughts about this.
