The Pentair Pentek Solar Drive PSD15 is an off-grid solar controller that can operate any
approved Pentair Pentek submersible motor loads or operate approved alternative 3-phase
alternating current (AC) motor loads up to 1.5HP from solar photovoltaic (PV) power.
To size the solar PV array to your specific motor,
please consult with your local dealer or Pentair. A
typical diagram for a Pentair Pentek Solar Drive
operated solar water pumping system is shown in
Figure 1. The solar PV array must be connected to
an external DC Disconnect and then to the Pentair
Pentek Solar Drive controller. The Pentair Pentek
Solar Drive controller should be installed in the
shade (potentially mounted under the PV array)
and away from the direct sun.
The Pentair Pentek Solar Drive can accept up to
two digital sensor inputs. For example, in solar
water pumping applications, an optional float
switch can be connected to the Pentair Pentek
Solar Drive to monitor when a water tank is full, or
a pressure switch can be used in combination with
a pressure tank.
