Bill- JKB should be fielding that question. He is wayyy more qualified than I. I sure hope he jumps in here. Basically, AC opens up your pump options.
The pump listed by Edit earlier in this post was the AC version of the exact same pump I have been using for the last 5 years of testing. Except mine is the 12VDC version. IMHO, there would be no advantage for him to invert and use that AC pump.
mnfish,
Not knowing squat about solar, I've been reading a lot of technical manuals and have the bloody eye syndrome.
As you said, there is a lot too this and needs to be sorted out. I mean, reality from hype.
Without knowing the quality of power coming from solar, it's difficult to answer some questions, but am narrowing it down.
Probably one of the only, commonly produced, AC single phase motor's you could run "raw" from the AC output of solar (without grid connect) is a PSC (Permanent Split Capacitor) motor. There are others, but this would be most common that could work.
I'll have more later.
