We just purchased a Whynter 45G fridge/freezer to keep our pup's raw food cold.....I'm concerned about battery usage while @ Q we have 2 120W panels....below is the usage chart from Whynter...any thoughts appreciated as always.

Don't need no freezer tonite!
Your battery capacity is going to be way more than on the chart. The temp that time of year will probably put you in the 77 deg. chart. What AH's the 2 125 watt panels put out depends on clouds and sun angle at the Q. You definitely have enough battery power to go through the night and if you need to supplement the solar just use the generator.
Hans, will you need to run your main inverter to provide power to the fridge? If yes, you may want to do a trial run at home.
My magnum 2812 inverter puts enough load on my batteries that they are low by morning if I leave it on overnight. Since Barb and I both use a CPAP keeping 120v available is necessary. I solved my battery problem by installing a few smaller inverters for specific uses. 2-300 watt and a 700 watt.
After a home trial you may want a smaller inverter just for the Fridge. Running your generator will likely also be necessary, since you don't have a lot of solar. I have a 170 watt panel and I run my generator twice a day. I almost never use my big inverter anymore.
Steve, his fridge is also 12 volt. No inverter needed
Hans- running your fridge and other items will depend on your battery capacity. We replaced your 2 8D AGM batteries a few years ago and they should still be good knowing how well you take care of them. The real issue is your total usage in amp hours vs what your solar generates, the balance can be made up by running your generator.
I know you have an Amish cooling unit on your refrigerator so that should not use much amp hours. I suggest installing a power meter like a Victron 712 or Triametic ( spelling doesn't count) so you can monitor you amp hours used overnight. I finally broke down and got one and I am amazed at what uses power and what doesn't. Of course, how you use your power in the evenings after dark has a lot to do with it.
Looking forward to seeing you & Marjet soon- safe travels. ^.^d
