An irrigation system includes a first valve fluidly-coupled between an inlet pipe and an outlet pipe, and a second valve fluidly-coupled between the inlet pipe and a power harvester. The power harvester generates electrical power at a power output in response to fluid flowing therethrough. An energy storage unit is coupled to the power output to store generated voltage. Comparison circuitry compares the generated voltage to a threshold. Control circuitry causes the second valve to permit fluid to flow therethrough when the generated voltage is less than the threshold, causing generation of the electrical power by the power harvester when the generated voltage is less than the threshold. The comparison circuitry causes the second valve to prevent fluid flow when the generated voltage is at least equal to threshold, ceasing generation of the electrical power by the power harvester when the generated voltage is at least equal to the threshold.
