I have a hobbyist lathe with a single-phase 115v motor of 3/4 HP. This motor turns on normally when I am connected to grid power, and VERY occasionally when connected to solar. But most of the time on solar the motor does not spin up. I’m wondering what I can do to allow it to start on solar.
My solar system, when running on batteries alone, can produce at least 70 amps output for several minutes at least (I have tested this with an electric heater and the battery monitor shows 70 amps coming out of the batteries when the heater is on). I wouldn’t think the 3/4 HP lathe motor would take anything like that for startup amperage, but perhaps it is possible.
Could adding some additional start capacitors to the motor cicuit help in this situation?
