At 350 volts you need about 10 ~200 watt panels in series. Each panel has a running voltage of about 34 volts. You would have about $2k just in panels and probably close to that in racking and wiring. -
I would guess that it is mppt and you should be able to do what you're asking. You should contact Franklin and ask them. Please keep this thread updated I would love to know how this gets resolved.Leave a comment:

I have not used a Franklin solar pak but I would guess that they're made for someone like you. Since you already have a three phase motor it should be plug and play.Leave a comment:

Might be better into looking how to swap the 3 phase for single so you can use any conventional generator. Per the Franklin AIM manual you need a 10KW externally regulated or 5KW internally regulated generator to start that pump.
Also, Franklin does make a kit that converts a 3 phase motor into solar. Check these out: http://solar.franklin-electric.com/products.aspx#Tab4. Looks like you've already got the 3-HP three phase motor. Might look into what it would take to get this going. You'll probably save in fuel what it would cost to convert after about 5 years.
Also, it would seem that with a 350V panel configuration I could only have one string. Would it be reasonable to hook up 2 strings of panels at 350V (which could produce up to 16 amps). This would put it outside of the power range on their documentation but it would seem that the controller would only pull the amperage that it could handle. My thinking here is that the extra string would power the pump during cloudy periods.
Does the controller have a buck converter or MPPT capabilities?

VFD - Variable Frequency Drive
You can get a electronic box that converts single phase, to 3-phase and soft start.

This is likely the easiest route.Leave a comment:

Do you know the starting amps using an ammeter?

is 208 VAC phase to phase. 3hp is only going to run around 3KW or 1KW per line above, or 8A. A typical
mechanical generator has some surge rating; I wouldn't design for a run rating of the starting surge. The
rotating machinery gives some extra energy. My 8HP 4.5KW generator managed to start up a 4HP air
compressor, yes everything dimmed and slowed but it worked. 2 HP car lift, no problem. Bruce RoeLeave a comment:

Still gonna have a hard time getting that much water unless you use multiple wells/windmills. I would still go solar on multiple wells. Solar is about 1/2 the cost of wind and much easier to maintain.

missing the pic tube and had continuous tuning (still have it). I learned that good
sound was way more important than the picture. The old time radio guys
understood that, and though the sound was only 1% of the bandwidth, the FCC
enforced using 10% of the transmitting power for sound. The picture had to be
REALLY snowy before you couldn't hear the program. Todays digital guys didn't
get it; the sound drops out all the time.
My second TV had a 7JP4 crt. If you want to call, use my land line. My daughter
eventually bought me an answering machine. Bruce RoeLeave a comment:
