I am interested in powering my pool pump during the daylight hours (10-12 HRS) using solar panels. I am also wanting to design some kind of switching that will switch it back to grid power whenever I need to run pumps in the late evening. Has anyone used solar on their pump. I do not have a pool yet or know what pump I will be using, but am just researching this to see if it is worth the money. Do the Intelliflo have some kind of output contact that can operate an external relay. Would love to do the switching with the touch of a button.
