AC/DC Solar Pumps - Generator/Grid Compatible

Thunderbird Solar AC/DC water pumps are designed for submersible pump applications that require daytime solar operation as well as applications requiring generator or grid backup.


Manufactured with simplicity of installation in mind, these pumps have built-in motor drives which allow for direct DC connection, built-in dry well sensors as well as a simple monitoring device for AC/DC power transfer and digital system controls.

​

  • Compatible with solar power and 1ph 230v AC generator or grid power

  • Automated power transfer available

  • Both high head helical pumps and high flow centrifugal pumps available (see performance curves below)

  • Enhanced functionality and lower cost than similar legacy solar pumping lines
