This is the thing that has kept me from wanting to go off grid complete minus fossil fuel sources. I could never feel that the battery system was really up to what the solar was able to handle. Maybe if the truck could couple with a couple powerwalls, or have the ability to supplement in extreme use. Yet need off grid really. Plus wind? I see the new designs for these Cyber truck houses all over instagram. Seriously doubt a truck could reverse power those places for very long. Ancillary power sources must be present.
