[RE-wrenches] PV solar powered pond aeration compressor

[R Ray Walters]

Windy was our best resource for DC air pumping. I recall brush wear,  and other high voltage arcing problems.
I remember  using an AC air pump (simple magnetic coil) with a rectifier, also. Never heard from those customers again,
 so 'No news= Good News"?

I'm not sure how to calculate the pressure and volume needed but a similar 120vac pump draws about 1200 watts and delivers about 9 CFM. I assume that the same wattage DC motor would mean comparable air supply. Any experiences out there?
