Sizing Layout

S (Suction head): Vertical height from the water level to the pump inlet where the water level is below the pump inlet.

D (Pipeline inner diameter)

L (Pipe length): Entire pipeline length. Ellbows and armatures must be added as an equivalent length of pipeline.

M (Motor cable): The cable between controller and pump unit.

T (Tilt angle): Angle of the PV generator surface from the horizontal plane.

Technical Data

System Overview

* PS DataModule is included in all PSk2 controllers and any PS controllers with –D in their description.  –D variants should be ordered if there is a potential need to use the PS DataModule features in the future as this is not a retrofit option.

**Vmp: MPP-voltage under Standard Test Conditions (STC): 1000 W/m² solar irradiance, 25 °C cell temperature

PS DataModule – Integrated Data Logger and advanced pump management features. Allows for simple system configuration, real-time and stored data plus provides Bluetooth communication to PumpScanner Android ™ App and PS Communicator.*
