For the electrical engineers that really want to get into the weeds on this, real question for you.
IF you had a Tesla truck and TT and ran out of power in the desert southwest. And you had a trailer with 400 watts of solar, and a 430 Amp/hr battery pack. Along with a 1500 watt inverter.
How long would it take to generate enough power to get the truck, without the trailer, 20 miles, to a real power source for recharging if you dont run anything else in the trailer?
It may be a lot better than I am guessing, but I really do wonder if there is an optimistic answer.
That there is a self sufficient method is a positive, just curious if the method would be real world useful.
