Thanks guys. I realize I am asking some simple questions (ok they are a little stupid) but I am new to solar systems so thanks for being patient.

I purchased the kill-a-watt meter from here and will use it on each appliance, the fridge and deep freezer for a week each and get some real numbers.
Also I purchased the book:
Photovoltaics: Design & Install Manual
From this site and will do some homework before I come back to this group with another post.

I know, you wanted to suggest that but I got to it on my own Smiley
Little by little this is starting to come together for me.
Thanks again for your opinions.

The calc I came up with is
Refrig = 1200 watt-hours per day
Freezer = 1000 watt-hours per day

I am new to altE and am very pleased with the site and the education available.
I will be purchasing a new solar system and building the system myself, component by component.
The only thing I am unsure about is how I have architected the system.  So please let me tell you what I have sitting in my altE cart and why and then maybe you can confirm if my choices are good.
I want this system to power my refrigerator and freezer, that’s it.  It will be off-grind only.
The only component I own right now is 4 gel 12v 90ah batteries. Everything else is being considered. I know I will need approx 15 batteries for a complete system but this is what I have today.
A friend suggested this solar panel
The charge converter I am considering is:
Morningstar Tristar TS-MPPT-60, 60A MPPT Charge Controller
 And the battery monitor I am considering is
Bogart Engineering TM-2020 TriMetric Meter Battery Monitor
And of course the inverter:
Go Power 1000W GP-1000 12V Inverter
What do you think so far ? acceptable choices or can you suggest something different ?
I picked the Morningstar Tristar cause it has the ability to handle 6 of the solar panels above and it can select the sealed/gel battery.
Also, I would connect the panels in parallel, so the volts would be 17.4 total and the amps would be 780
I just want to be sure before I go and do a cart checkout and then learn later on that I missed something
