Have any of you tried this? I have a T240 auto transformer supplying my panel board in our cabin which feeds our deep well pump. The well pump is our only 240 volt load, it seems this is not the most efficient setup as the transformer has a 12 watt hour consumption. I am thinking about removing the T240 and installing a more compact T220 transformer on the load side of the well pressure switch so it is only on when the pressure switch calls for it. The well pump is a Grundfos SQ series soft start so I am hoping the in rush current to the transformer and powering the well pump will not be so severe, as this configuration would burden the inverter more than the present set up. Is this worth the effort?
