1   Scope and object This International Standard defines the requirements for design, qualification and performance measurements of photovoltaic pumping systems in stand-alone operation. 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

• System design parameters and requirements

• System specification

• Documentation requirements

• System design verification procedure

The object of this standard is to establish requirements in o...
