I’ve been wondering how to improve our well pump so it can run off our generator in our RV or install a windmill to it.
The well pump is likely 240v, your RV generator may just be 120v.
You can create split phase 240v from single phase 120v by wiring a 1:1 isolation transformer in a proper configuration. Most small gensets don’t use a 4-wire plug (split phase) so it can be useful to have one of these
