We aren't talking about inspected installations here, my wall doesn't look like this anymore because I'm becoming legal, but you can still get these "ST-5000" power converters for $100 that have a toroidal transformer in it with taps labelled at 0V, 110V, and 220V. I tested it for a day after reconfiguring it as a a split phase autotransformer running a 120v ~2kw load behind it, and it didn't even get warm. I put a 3-pole breaker on it. I only had it so if I were in off-grid mode I could flip it on to balance the loads on my Deye better.
