I have an iSolar 1 and the solar pump is only getting around 78 VAC across controller connector #17 and #18 when the solar pump is blinking on the display. Input power is 120VAC across controller connector #19 and #20.
The unit is old can it be fixed?
If it can not be fixed, which new controller should I buy?
