New Pool motor and salt water Chlorine Generator? Intelliflo and Intellichlor?

You know Mr Parker, I'm not sure I can figure you out. Once minute, you sound knowledgeable to the point I'm thinking you are in the pool business, and the next you are talking about using a 3ph motor in a residential application!

Are you working commercial pools?

Regardless, discussions of roll-your-own VFD systems don't belong in the general discussions, so I'm moving this to the China Shop.

No I am not in the pool business but I was an engineer in the computer chip industry and was a Landscape contractor some 20 years ago plus did residential electrician work when I was in high school.
I am an engineer at heart and am always looking at how things are made and how can it be done better and cheaper.
I just have a residential pool and my electric meter was just upgraded so I can go onto PGE and see the electric use and their is a huge spike in usage when the pump turns on. I am just trying to decide what is the best way to lower the cost. Seems like their are two choices. VFD and 2 speed. Both are better then a single speed it seems.
Ok gotta get back to my project. At my moms house fixing her sprinklers.

And, when they upgraded your meter, they also upgraded your power from single phase, to 3 phase????

[mrrparker]

No but the VFD units will convert 1 phase to 3 phase. I am still researching and will post my results when I get some more information.

OK, I'll buy that.

But you are into a level of hobbyist experimentation that is very different from most of our members, and also not characteristic of most guys in the pool business. So, the China Shop is the appropriate place for your discussions.
