Locate the solar array and the controller as close to your water source as possible.
iSolar PDP pumps consume only low levels of input power, so it is important that
energy losses are minimised to ensure performance expectations are met.

The Max Voc (V) and Max Current (A) capabilities of the motor and the controller must be
respected.
Fitting additional panels or incorrectly rated panels will cause serious harm or
irreparable damage to the controller and motor voiding warranty
iSOLAR PDP3-250 power is supplied by a single panel.
