I really appreciate the great customer service and the helpful attitude of the RPS staff
I used the RPS 400 as a booster pump on a 3" flowing artisan well to fill a tank 300ft away and slightly uphill. The well still flows enough to keep the tank from freezing at night and the pump will easily water 200+ hd of cattle all day allowing much better management of both the grass and the cattle. Service was great pump arrived in less than a week and instructions were perfectly clear especially after watching the online video. Very high quality components, I have installed a few pumps and this one is great especially since it will fit in a 3" well. I recommend getting the mounting kit as well it saved me a lot of time installing the panels properly.
Works like a champ. Filled up a 1000 gal tank in about 5 hours from a well that refills itself at 3 gal/min. Low water sensor never went off, so the default pump speed is perfect.
The panel array is hinged, so I can rotate the array between vertical and horizontal, and I have stops at 12, 34, and 60 deg for summer, spring/fall, and winter solar flux. All 2x4 and 6x6 construction with strap hinges for the pivot point.
