    Running 230V well pump from 115V generator?

    I have a 115V Honda inverter generator that can put out 2200 watts. My well pump is 1/2 hp, which should be well within that power requirement, but is 230 volts. Can I simply install a step-up transformer to run the pump off my generator?

    My day 3: build a gsm monitor/alarm for a pump house

    Seems to be working ok, as in texting and calling. The mains relay's I have used are getting too hot, seems that the led resistor is of the wrong value so are dissipating too much heat. Have started to do it another way for the mains monitoring.
