Introducing the new stacked Merlin Series solar pump systems! 

These larger-wattage solar systems prove incredibly beneficial during periods of low light and cloudy weather, offering 60% more power on cloudy days than the K170 or K255. This system helps the pump produce more water and lengthen the pumping day by starting up earlier and running longer at max GPM.

  • Deliver up to 2,500 gallons per day at 5.2 GPM maximum, based on a 8-hour run time.

  • 2x M3 Solar Pumps. Using 2 pumps, redundancy is added and increased production is achieved.

  • High-voltage power switch.

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

  • API's extremely durable, adjustable aluminum mounts, wire harness, On/Off power switch.

  • Long life brushless motor, stainless steel Merlin3 solar pumps

  • No additional controller required.

  • Professionally built in the USA.

Bulk discounts available, please call for pricing.




No additional controller is required for API solar water pumps, however the ALC 1275 greatly increases the life expectancy of our solar 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.

Custom systems available up to 1200 GPM (Gallons Per Minute). Please visit our custom page to contact us.
