PENTAIR PENTEK

SOLAR DRIVE OPERATION
If the motor is properly connected, the Pentair Pentek Solar
Drive will begin the startup procedure. The green AC LOAD
LED (Figure 18) will have a solid green light, and the motor will
start running. Additionally, the Pentair Pentek Solar Drive will
immediately start performing MPPT operation over the solar
PV source. The MPPT operating range is 45 to 60Hz for 60Hz
rated motors, or 40 to 50Hz for 50Hz rated motors.
The Pentair Pentek Solar Drive has built-in over-load
protection, so if a connected motor has a power level higher
than the Pentair Pentek Solar Drive limitations, it first slows
down and tries to run the motor at a lower power level. If the
motor power continues to be outside the power range of the
Pentair Pentek Solar Drive, it will shut off the motor operation.
If there is not enough solar power, the unit’s SOLAR LED light
will blink yellow, as shown in Figure 19. This usually happens in
the early morning or late evening, or during overcast weather.
The Pentair Pentek Solar Drive controller will try to start the
motor once every minute. Each attempt will be indicated by
the blinking green LED. If there is not enough solar production
from the solar panels, the yellow LED will start blinking again.
Shutdown:
To stop the Pentair Pentek Solar Drive’s operation, the ON/OFF toggle switch on the bottom of the
unit should be used. Once in the OFF position, the Pentair Pentek Solar Drive will automatically
stop the motor’s operation.
However, if a tank or well float switch is used when the tank becomes full or the well becomes
empty, the Pentair Pentek Solar Drive will stop its operation, and the WARNING LED will blink red.
The WARNING LED will be solid red if the temperature of the Pentair Pentek Solar Drive rises
above 70°C (158˚F), at which point the Pentair Pentek Solar Drive will stop operating and wait until
the temperature drops. This can happen if the unit is exposed to direct sunlight, which should be
avoided.
If the Pentair Pentek Solar Drive gets too hot during normal operation, it will switch to Power
Deration mode, limiting the maximum power that is transferred to the motor load. During that
time, the AC LOAD LED will be solid green and the WARNING LED will be solid red. If the unit cools
down to a regular operating temperature, it will automatically continue operation without the
thermal deration. If the temperature of the Pentair Pentek Solar Drive continues to increase, it
will eventually stop operating, at which point the WARNING LED will be solid red.
