If you want to keep your residential fridge and want to camp off-grid, you have to have a generator unless money was no object, in which case spend the $19,000 for the biggest solar package Keystone offers.

And even with that kind of investment, successful "long term off grid camping" depends as much on where you're parked and how much sunshine hits the solar panels "at the right angle to provide maximum energy production"...
Just a couple days of "gloomy weather" can send even the best SolarFlex system to failure without alternative power sources (like that trusty generator)..
Parking in Arizona in the desert with "hot glaring sun" is significantly different than parking in northern Michigan in the winter when the sun's angle barely provides a couple hours of "solar panel activity" if you can keep the snow from covering the panels. Then there's those "pesky trees" in most boondocking sites that provide "cooling shade at the expense of direct sunlight"...
My take on it (FWIW):
SolarFlex 200/220 (OEM equipment) - Nah, might keep the smoke detector running in storage.
SolarFlex 400/440 ($1830 no batteries provided)- Might run the furnace a couple hours a night in cool temps.
SolarFlex 600/660 ($11430 with 270 A/H capacity) - Use the microwave for popcorn, but sparingly if you need the furnace.
SolarFlex 1200/1320 ($18930 with 540 A/H capacity) - Use the microwave for popcorn, maybe perk a pot of coffee and watch TV in the evening, but hope for bright, sunny days EVERY DAY or "budget your battery use carefully. Forget the Air Conditioner for more than an hour a day, otherwise, you'll be "in the dark come 11PM.
With any of the above systems, if you have a "residential 120 VAC refrigerator" you're going to have to be "vigilant about ALL electrical use" if you want to have "frozen ice cream"... And, running the ice maker when on "solar power" is a "HUGE consumer of battery power that could be better used for lights or furnace"
The SolarFlex systems offer "some glimpse into the future" but none of them are "right for off grid camping for sustained trips if there's any interruption in the sunlight on an "every day basis"....
