Thanks! That sounds promising. I'll investigate. I should have no difficulty providing whatever signal it needs and derive it from the "solar pump" control 24VAC output that's not used. I believe this corresponds to the JVA on solar. The Sta_Rite pump itself is in good shape as it was replaced less than 5 years ago. So what you are saying is this Vgreen motor can simply replace the existing Sta-Rite motor leaving the pump. Do you run the filter 24hrs/day? It seems a shame to run it during peak PG&E rates in the summer evenings. So I think you are saying run the motor all the time but program it so when the JVA solar signal is present, it shifts to the faster rate I determine for optimizing my solar flow. Can it be programmed for any rate for the 2 priorities suggested? Is there some reason it would not be set up to run at all times except 3-8 weekdays due to peak rates.
And its only about $500 and easy to install... Excellent idea! thanks.

Got it. Looks pretty good. seems pretty straightforward. It even says its compatible with my Sta-Rite Max E Pro so I presume its just unbolting the Sta-Rite motor, bolting on the V Green, hooking up permanent 240VAC, building my Jandy output to Vgreen circuit for the solar JVA signal, determine my best speeds for pool filtering and solar and programming it. Is there some reason it couldn't be programmed to start at say 11PM ( or so) on slow speed and run slow all night on off peak rates until my jandy control input came on around 9-10AM till about 4PM ( when it was sunny and hot) but shut itself off when the PG&E rates were high and the solar was not working at around 4PM. Then come back on each night. It wouldn't save much. The filter time flow would need to be high enough for my cartridge filter to achieve adequate pressure.
