Q: Do your solar pumps have to a controller?

A: A controller acts like the transmission in a vehicle. It lowers the voltage and raises the current to run the pump, however slowly, in low-light conditions-like shifting to low gear. The controller also protects the motor from overload and over-speed and provides low-power float switch control.  Controllers will increase system performance approximately 30% over the course of one year!
