I think what you're asking is about the lack of resources, that would be because solar is still limited. My mother tried to run her agricultural facility off grid. It winds up with propane generators in key locations where the batteries can't store enough electricity, etc. Her house had some DC appliances, some AC, gas furnace, stove and oven. Large and small solar trailers for places she didn't even have panels set up. After more than a decade of problems, she threw in the towel and had the grid installed. Lucky for her the distance had been shortened by several miles by then. But even in the beginning it would have cost less to bring the power to her that way than what she spent. Though the trailers are of course still in use. They have been the most practical because they see less demand. The moment I hear someone wants 240v I assume they want a 40amp breaker, that's now 4 times the wattage per outlet, not twice. Don't think about unlimited power off grid. Think very low power usage.
You can run at 240vac from the panel and step down. It's available, not sure it's so practical for most people. I would say the more you need to DEPEND ON your 240v, the less you want it to be solar. The more you want to depend on the solar, the less you want to demand from it. On grid you'll have your power either way, so it doesn't matter your own power will be unstable. But I want a bigger than local power outlet in my garage to run something you don't normally find in a residential garage, but I could run a 10kw motor several times a week from a battery solar charged. . . .
