6 FAQs about [Photovoltaic power station inverter test standards]
How do you test a PV inverter?
To test a PV inverter according to IEC 62093, identify a suite of accelerated tests to identify potential reliability weaknesses. Develop recommendations for how the tests are to be performed, including sample size, environmental test conditions, duration, power and monitor, etc. Provide a baseline for comparison of reliability performance between PV inverter manufacturers.
Are standardized tests needed to ensure reliability of PV inverters?
Accepted standardized tests are lacking to ensure reliability of inverters for the PV industry. This section discusses the status of tests used or being developed to gauge reliability, including design qualification tests.
What is a standard for photovoltaic systems?
Current projects that have been authorized by the IEEE SA Standards Board to develop a standard. Tests to determine the performance of stand-alone photovoltaic (PV) systems and for verifying PV system design are presented in this recommended practice. These tests apply only to complete systems with a defined load.
What are the safety standards for PV power conversion equipment?
Safety standards The IEC 62109 series is the international safety standard for PV power conversion equipment. Part 1 is IEC 62109-1:2010, “Safety of Power Converters for Use in Photovoltaic Power Systems – General Requirements.”
Do PV inverters need safety standards?
Applied safety standards for PV inverters provide a rudimentary level of reliability testing, insofar as they relate to safety. Considering the lack of generally accepted reliability standards, some apply draft standards in development and portions of standards from other industries.
Are PV modules adapted for use in inverters safe?
Some tests applied to PV modules adapted for use in inverters are for mechanisms in PV modules, without a clear analog mechanism in inverters. Applied safety standards for PV inverters provide a rudimentary level of reliability testing, insofar as they relate to safety.
