Pentair Pentek
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
immediately performs MPPT operation over the solar PV
input to offset AC source power.
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 the AC switch on the right side is ON, then the Pentair
Pentek Solar Drive is automatically in Blending Mode, using
as much power as is available from the solar PV panels, while
automatically supplementing on an as-needed basis from the
AC power source.
If the AC switch is in the OFF position, then the Pentair Pentek Solar Drive operates in Solar
Only mode, and it will not draw any power from the grid, but will balance the power from
solar with motor power by varying the motor frequency. If there is not enough solar power,
the unit's SOLAR LED light will blink yellow, as shown in Figure 19.
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 80°C (176˚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.
