From the prompt delivery of the system, ease of install, flawless operation. Even more so is their customer support and SERVICE! 1st- cows got to control panel and damaged it. Called and they had the panel to me in 3 days. Just recently, had an issue with the tank level sensor. They sent a new sensor, no charge and had within 3 days of my call.














RPS 400V+ Solar Well Pump Kit (High Volume)
🌷 Spring Bundle Sale + FREE SHIPPING* (Ends 3/31!)
Requested by customers for over two years, in 2018 we were proud to introduce our new centrifugal pump! When a helical screw pump can't get you enough volume and the Pro Series is a little too much pump or money, the RPS 400V or 800V is for you. Using the same great controller as our famous helical pumps, we have created a higher volume, lower head option. A centrifugal pump works best for sandy or sedimentary water sources, the pumping mechanism impellers are highly resistant to wear. The RPS 400V uses less panels but the same pump as the RPS 800V. Adding more panels increases head ability and volume, up to 16GPM at low heads! Perfect for keeping large stock tanks or ponds full in the summer.
Featuring permanent magnet DC brushless motors means you'll never replace another carbon brush! The entire pump housing is stainless steel to comply with all local code and pump installation requirements.
RPS is a growing 100% American-owned company of friendly, helpful solar water specialists who love our dogs, tractors, trucks and coffee. We are honored and blessed to have such great staff and customers all over this great country.

All your videos are spot on. If people took the time to watch them before installing they’d never have to call you. I loved the user manual. The way my wife follows her recipe for cooking… that’s how I followed your user manual. I loved it. Every second of it. I’ve never had customer service like this.

RPS is now one of my very favorite companies.With the help of Daniel, I purchased a 6000watt Water Secure System. It was a great project to install and brought me back to using some skills that I haven’t used in years. It worked perfectly as soon as I turned it on.

We’re getting close to what, roughly five years but it’s working fine still.It’s been the best investment we’ve ever done, sir.Seriously. Oh yeah, the best thing we’ve done. We don’t have to run a generator, we’ve got plenty water, it’s always full, it always works and we can almost turn back on it.
