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

TBS AC/DC helical water pumps are designed for low flow (2-12GPM) and high head (50-800ft) applications. These pumps are capable of operating off direct solar power or 120/230Vac generator power. Made with simplicity in mind, TBS 4" pumps have built-in motor drives as well as a plug and play monitoring device for AC/DC power transfer and digital system controls (float switch, pressure switch, etc.).

Dry well sensor built-in to pump wire for protection of pump against low recovery conditions

Positive cavity pump using wear resistant screws and rubber stator for longer pump life 

Molded shaft for increased durability and reliability over time

Built in motor controls allow for dual power operation (DC or 1ph AC power) as well as motor protections such as over-temperature, overload, and over and under-voltage

TBS AC/DC stacked impeller (centrifugal) water pumps are designed for operating off direct solar or 120/230Vac generator power. TBS 4" pumps have built-in motor drives as well as a plug and play monitoring device for AC/DC power transfer and digital system controls (float switch, pressure switch, etc.). The perfect option for varying flow rate requirements and high TDS water content where helical pumps are not viable.
