Q: Will a solar pump stop pumping once the tank is full?
A: DIFFUL solar pumping systems utilize a controller that among other things will accept the input from a float switch in your tank which tells the pump when to start and stop. We will give you a float switch in our accessories. Some of the other functions of pump controllers are low water cut-off, lightning protection and load matching through the use of maximum power point tracking from the solar array.
