INTRODUCTION
Isolated System
The SD700SP is only connected to the PV field, generating the necessary power to start and speed-up
the pump. The minimum power required depends on the hydraulic response of the complete pump-load
system. A complete study of the system determines the motor operation frequency range, (typically from
30Hz to 45Hz), which generates a minimum pump flow. At the same time, the frequency range
determines the minimum power threshold and therefore PV sizing.
With the MPPt dynamic search algorithm developed by Power Electronics, the SD700SP searches for
the Maximum Power Point automatically, therefore the PV field will always supply the maximum power
available. Irrespective of whether the system is working in winter or summer, or of the intensity of sunlight.
