Is anyone using a 120v-240v step up transformer?
I was fortunate to get a 30kW 3phase 240v-480v transformer from my boss when we built our home. I now have 3 transformers that are good for 120v-240v. I use one to run the other side of my panel when I run inverter or smaller inverter generator. I am thinking to run my panel at strictly 120v and using a smaller 120v-240v transformer for the well pump.
The point is that these transformers are easy to find and inexpensive. A buck-boost transformer can be wired for either 120v or 240v. You can ignore the secondary of these transformers and just use the split primary to get 240v. If you like the inverter generator but are confounded by the limited offering at 240v then take a look at a transformer to get to 240v. The transformer will also provide some leakage reactance which may limit the starting surge in a well pump situation. The transformer will have it's own surge so I say may. The transformer can be energized first, and then switch on the well pump.
