PSk2 SmartSolution introduces hybrid power solutions to
the PSk2 system.
Using a combination of the SmartPSUk2 and SmartStart the
PSk2 system can be powered by solar, by AC power from a
generator or grid supply or with a mix of solar and AC pow-
er.
The PSk2 controls the SmartSolution components to deliv-
er water depending on power available, time or specific wa-
ter requirements.
• To connect PSk2 to an AC 3-phase grid power supply
then a SmartPSUk2 is used
• To connect PSk2 to an AC 3-phase generator then a
SmartPSUk2 and SmartStart is used.

15.1 Solar-diesel system sizing considerations

The SmartPSUk2 is able to switch between solar and diesel
as well as blend both power sources, e.g. to obtain a desired
flow rate or pressure irrespective of sunshine.
QTY
It can operate on diesel generators with a constant power
1 unit
rating higher, equal or smaller than the power rating of the
pump motor.
1 unit
The constant power rating of the diesel generator should be
4 units
selected considering the desired flow or pressure.
