Not quite, thats just how the rough numbers worked out in this case. When people want me to spec up a stay in place system theres a lot more questions and real life testing done to confirm numbers because no one runs "just a fridge" everyone has a lot of other little things that add up over time.
For the numbers I threw down for you I basically took the numbers for my system, doubled the fridge draw left the misc values totaled them then doubled it for the solar watts needed and rounded up to the next convenient panel size. I then doubled the aux battery capacity to deal with the extra fridge over night. What should get you though on that is the doubling of the misc values + the round up factor combined with the benefits of the bigger batteries and the traxide. IT should get you to about 7 maybe 8 days but you'll still wind up against batteries in a lower state of charge than when you started.
For the stay and live on solar deal you need (roughly) 3 times the amount of draw you expect the system to deal with as your charge ability and thats only properly viable while everything is 100% in reality i'd spec up nearer to 4 times.
With that you're running essentially the same system I am, with just a single engle and no accessory load that will just about keep you infront indefinately but add some sub optimal charging factors, some lights, a radio, charge a phone and the laptop and you're behind. I think that this will get you about 3 days in location but the battery will be drained on day 3 and you'll need to move on to charge the batter(ies). The traxide will give you a little more by the magic it does But I dont have one fitted because of a very special way I need to be able to abuse my setup that the traxide system was never intended to deal with (jump starting 24V out of a 12V system and welding off the batteries)
The configuration and build sequence you really want here is a little different..
Fit the 80w panel to the vehicle, add its regulator and couple it to the main batery. Your now set to go with a single fridge for about 3 days. Your system, charge wise wont be any better than mine but you have the advantage of the traxide which in terms of real life will put you about 30% ahead of how my setup works. maybe more if you use better batteries, panels and regulators. I've put this first as it sounds like you already have all of this gear.
next get yourself the upgraded traxide you wont see an obvious and immediate change to how your system works but trust me for the next bit you will.
then get yourself a second panel set or array when you start hooking up the next fridge/freezer. This set you hook up to your aux battery or the anderson plug with a dedicated regulator.
This gives you the most cost effective and flexible setup. youve got a panel set on the vehicle that looks after the main battery all the time and via the magic of the traxide the aux battery as well when the main battery is mostly charged. (which means you're not letting solar power goto nowhere when the battery is charged)
When you expand you have a second complete solar system that is not anchored to the vehicle so you can use it elsewhere or position it else where and with the newer traxide looking after things if you have to park the vehicle in the shade you can use the solar or any other charger to get all the batteries back up. IF you want you can even remove the second (third) battery and mount it to the second solar system to look after one of the fridges if you need the space in the vehicle.
if your parking it all up you can put the small maintenance panel onto the system anywhere and it will look after everything. (with the early traxide you must connect to the main battery with the later any will work)
