I think the use of the AC freezer is going to be dictating at how you approach the solar use. You should definitely use a Solar calculator to add up all the devices you want to power but the freezer is going to rule all.
If the freezer averages a 1.3 A draw and say, a duty cycle of 1/3, your total draw would be around 100 AH/day at 12V. Two 24V modules and a good MPPT controller would probably be a good fit. If you have batteries that need the 15V, the better controllers have a PC interface where it can be set, easily.
The downside of the bigger modules is that they are bulky to cart around. I wouldn't want to use one or more as portables because I'm old and lazy. You may feel different.
Oh, BTW, if you can, put some foam sheet insulation around the box. It really helped the duty cycle on my fridge.
