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...
