Complete Water Pump Systems

N250RP4 1800 GPD


N250RP4 1800 GPD $1,760.00

The N-series API systems are similar in strength, durability, and production as the other complete solar systems, but are recognized as having more efficiency that complies with NRCS, the government’s conservation standards.

Please contact your local FSA office to check availability of funds & product eligibility.

This N250RP4 solar pump will produce more water and lengthen the pumping day, even during cloudy or reduced sunlight days. This is due to having 30% more power than the K170 or K255 systems, allowing for earlier pumping and longer runs at max GPM.

  • Deliver up to 1800 gallons per day at 3.3 GPM maximum, based on a 9-hour run time.

  • Max Depth 100 ft.

  • UL Listed solar panels include a 25-year power output warranty.

  • Extremely durable, adjustable certified engineer stamped aluminum mounts.

CE Mark


  • RP4 pumps require a 5” or larger well casing.

  • N250 panel systems require a 2 7/8” OD pole.

  • Flows decrease as depth and pressure increases to maximum depth of 100 feet (43 PSI).


At times the government will provide rebates or tax incentives for solar pumping systems that meet their requirements through the NRCS. Contact your local FSA office for availability of funds and eligibility.

No additional controller is required for API solar water pumps, however the ALC 1275 greatly increases the life expectancy of our aluminum pumps and prevents unnecessary wear and tear on the pump.

Please be sure your well has been tested for flow rate and continuous flow supply. In order to reach these water demands, your well must be able to keep up with the solar pump. Otherwise, damages can occur.

  • Do you have wind turbines within 1/2 mile of your solar pump system? Find out why your system can become damaged here.
  • Don't forget to prep your system for the winter!! Weep holes are a must!
  • Ground Rods are great for preventing damage from lightening spikes, we highly recommend ground rods for solar systems.
