My son is getting solar water installed and we've decided to install the new motor & pump ourselves.
The solar company said a 1 1/2 hp would work to push the solar properly.
The one we will be replacing is a Century with a label "Total HP = 1.24. The specification plate says HP 3/4. I don't understand that.
Also, he has a booster pump for his pool sweep (pressure type). Is that likely to interfere with anything?
I'm inclined to go with a 2HP pump and motor, or a 1 1/2 pump and motor, preferably Pentair or Hayward. Is there any benefit to having the motor oversize by 1/2 HP?
I could use some suggestions for a good budget unit. He doesn't have water features to speak of.
Should we decide to look at two speed again, do they have a sensor to switch to high speed when the solar calls for water and more power is needed? Or is it more complicated than that?
