When a smaller pump just won’t cut it, choose the RPS2.1-100. Few 3in solar well pumps can compare to the enormous power of this 450-watt monster. This pump features maximum head of 328 feet and flow rates up to 9.2 gallons per minute. For example, with 250 ft head, this pump will produce 5.2 gallons per minute.

These pumps are designed to operate on solar power and feature a brushless DC motor. Never replace another carbon brush! The entire pump housing is stainless steel to comply with all local code and pump installation requirements.

Each pump comes with a maximum power point (MPP) tracking control unit to ensure maximum performance for the present conditions. These controllers are far superior to directly connecting the pump to the solar panels since they automatically adjust current and voltage to ensure maximum power generation. The maximum power point tracker includes a low water sensor to ensure the pump does not run dry and optional high water sensor to ensure the storage container does not overflow.

Included in the complete system are eight (8) 100-watt mono crystalline silicon solar panels. These panels feature tempered glass for impact resistance in severe weather conditions. Each panel has one male and one female MC4 electrical connectors for easy waterproof hookup.

    I could not find a better price online for a system of similar performance. Not sure how they do it, but they do!

    I purchased over a year ago and everything has been working as expected. No issues, no regrets.

    I own four RPS pumps. The water table varies on my properties and its been essential to have pumps that can handle different depths. The guys at RPS are great. Helpful upfront but also when I called for help installing my first kit. (its easy by the way I just had a brain fart) That’s when you can really tell a good company. I’ll probably be back again later this year.

    My husband had this installed in an afternoon and we had water in the garden hose by nightfall. Love this thing! Still need to get the panels off the yard and on to the roof but it’s working great as is. Recommended

    Was asked to leave some feedback. Like the system. Took a while to get all the parts but its working well now. Pumping water into a stock tank for 25 head. Been about for 3 months now. Am happy.
