I posted the original installation of this dc pool pump back in 2012.
I am on my second pump only because the shaft bearings failed in the DC brushless motor a couple of years ago.
I was able to measure and source out replacement bearings as they are a common size (so now I have a spare pump).
These shaft bearings are also pretty simple to replace.
The original controller is still functioning without any issue.
The lorentz is a great product and manufactured well.

I see more of these solar pump systems on the market now, out of china. If anyone out there has experience with these, would be nice to see some reviews.

Aloha
