Standards Development

Scope

The outlined measurements are applicable for either indoor tests with PV generator simulator or outdoor tests using a real PV generator. This standard applies to systems with motor pump sets connected to the PV generator directly or via a converter (DC to DC or DC to AC). It does not apply to systems with electrical storage unless this storage is only used for the pump start up (< 100 Wh).

The goal is to establish a PV pumping system design verification procedure according to the specific environmental conditions. This Standard addresses the following pumping system design features:

 Power vs. flow rate characteristics at constant pumping head

 Pumping head vs. flow rate characteristics at constant speed

 Start-up power characteristics

 Dry-run protection assessment

 System design parameters and requirements

 System specification

 Documentation requirements

 System design verification procedure

The object of this standard is to establish requirements to be able to verify the system performance characteristics of the PV pumping system. For this purpose, the test set-up is outlined, the measurements and deviations to be taken are defined and a checklist for the data mining is established.
