Yes! This would lead to a lot of creative folks coming up with different solar designs. It would be so cool to have a built in MPPT with a simple + and - MC4 or similar plug that would accept a decent range of DC voltage and amps. This would be one of the coolest features for a CT in my opinion. Not particularly useful everyday, but definitely a major cool factor.
The inverter in the truck will not be large enough to power a house. Only a few critical circuits like your fridge or freezer.
The CT inverter will be 30A at 240V. That's 7.2 kW. I have a largish house and pulled, on average over the last month, 3.7 kW. The average American house uses 30 kWh per day. That's an average of 1.25 kW. And the truck will have a 200 kWh battery so it would last the average guy 6 days (and me more like 2). So clearly no problem with the inverter size as long as the peak loads are controlled (big ones shed). Lots of people install transfer switches and use 5 - 7 kW generators for emergency power. The CT is eqivalent, in terms of power deliverable to a house, to one of those.
Not really. Today's inverters are better than 90% efficient.
You missed the point. It is that the CT is potentially quite flexible in terms of what one can do with it as a load leveler. Unless Tesla does something to prevent or make it difficult to use it as such.
While that's impressive, it won't handle most houses. A water heater would use half that, and a central air conditioner would use almost all of it. You wouldn't be able to use them both at the same time. Much less any of the other loads a typical house has.
I can power my house on a 50a drop,
I don't know where you are getting these ideas but as I mentioned in my last post I averaged 3.64 kW over the last 6 months which is 87.6 kWh/da, almost triple what the average US house takes. Median draw was 2.8 kW. I exceeded 7 kW 10.6% of the time. My baseline load was 1.65 kW. Given that power consumption (or at least mine anyway) is baseline plus a Weibul distributed random load it is pretty easy to suppose that the average house might have a baseline 1/3 what I do and that the difference between the median and baseline might be 1/3 of what it is for me. With those assumptions its easy to estimate that the probability of exceeding 7 kW is 1E-5 (0.001%). In a year it would be exceeded 5 minutes. For me it would be 929 hours so I wouldn't even try to run my whole house on the CT or a 7 kW generator. Now I would not hesitate to put 40 or 50 amps of loads on one of those priority circuit transfer panels they sell for this application with small generators. Their ubiquity should be sufficient evidence that you can indeed do what you are saying you can't do. Millions of people do it. Intelligent load shedding is, of course, part of this. Assuming it's a power emergency that has caused you to hook up your house to your CT you tell Mrs not to bake cookies in her electric over, fire her most recent pottery project of dry clothes until the power is back on. Not only does this protect the gnerator/inverter from overload but it makes the fuel/charge last longer. If you are hooked up legally no load of that magnitude is on the transfer panel. It is only connected to refrigerators, lights, communications, the well pump etc.
I get these crazy ideas by using math. Average loads really aren't relevant. Peak loads will exceed what the CT can supply. As I said, a central AC unit will use almost all the power it can supply. If the water heater kicks on at the same time, it's not going to be able to handle the load.
