CEI EN 62253

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
order 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.
