I've been reading on the board here that most 2 speed pumps cannot prime solar panels, but that it may be possible if the pump ran on high, then switched to low? I have an installer scheduled to come out and install 7 FAFCO Sunsaver panels. I have a 2 story house. My pump is a 1.5 HP Jandy Flo-Pro 2 speed pump, with cartridge filter. I have no water features or spa, and dual Intermatic timers (one controls on / off, other pump speed).
Anyone know if it would be possible to start the pump on high, then switch to low? I want to get the energy savings of my low speed, rather than have to run the darn thing on high all the time.
I know I can get additional pins for the timers to cycle the pump speed - but I'm wondering if it will work. The solar installer doesn't like 2 speed pumps, which is not a good sign.
