Total Dynamic Head (TDH):
Static head plus friction losses.
Vertical height from the dynamic water level to the highest point of delivery.
Pressure losses in the pipeline as height of a water column with the equivalent pressure. Proportional to the length, diameter, surface of the pipe and the square of the flow rate.
Pump end and motor.
Motor cable length:
Cable length from the pump unit to the controller.
PV cable length:
Cable length from the controller to the PV generator
Complete pipe length from the pump unit to the point of delivery
