Grundfos
SA-1500
Solar Direct SP Line of Water Pumps

The Grundfos solar direct SP line of water pumps should be considered by anyone who wants to do the job right the first time. The pumps are a stainless steel centrifugal design with no diaphragms to replace and a water-cooled motor. The Solar Pump 1500 series operates from a solar array of 7 or 8 modules in series up to 2000 watts. This series can pump water from a maximum depth of 650 feet. Common applications for this series of the Grundfos Solar Pump 1500 are campground water systems, livestock watering, irrigation, and larger community water systems.

The SA-1500 controller is a pump controller and an inverter. There are many pump control features in the controller such as maximum power point tracking, low water sensing, and float switch terminals. This controller takes the DC power from the solar array and inverts it to 65 VAC, 3 phase for the pump motors.
