DANSK DS/EN 62124 PDF

The specifications, test methods and procedures included in this document cover stand-alone PV systems. It covers systems containing one or more PV modules, a support structure, storage batterie(s), a charge controller and typical DC-loads such as lights, radio, television and refrigerators. AC loads with dedicated inverters are considered as DC loads. The load as specified by the manufacturer is an integral part of the PV system with regards to the design verification.
The focus of the test methods and procedures in this document is limited to system performance evaluation. Individual sub-systems and components may be monitored, but only to evaluate the performance of the overall system.
The results of this test are applicable to the exact components that are tested. Any changes in components or components' specifications require design verification.
The standard is valid for system testing both for outdoors in prevailing conditions and indoors under simulated conditions. The testing conditions are intended to represent the majority of climatic zones for which these systems are designed.
The object of this standard is to verify system design and performance of stand-alone photovoltaic systems. While individual components may by qualified to environmental and safety standards, the assembled system needs further verification, to ensure that the performance test consists of a check of the functionality, the autonomy and ability to recover after periods of low state-of-charge of the battery, and hence gives reasonable assurance that the system will not fail prematurely.
