6 FAQs about [Photovoltaic inverter performance test purpose]

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.

What is a test protocol for inverter efficiency?

Sandia National Laboratories and BEW have worked together to develop a test protocol to measure inverter efficiency as a function of AC output power and DC voltage. This protocol has been adopted by the California Energy Commission (CEC) and any inverter used in a CEC approved PV system must be tested by an independent lab to this protocol.

What is a photovoltaic tester?

A photovoltaic tester is a complete electrical test solution for verifying photovoltaic array performance. This device collects important data which will both help a technician in the moment and in the future as they look back on trends or common problems. Photovoltaic test equipment is often used for analysis [Read More]

Are photovoltaic module inverters reliable?

Conclusion The photovoltaic module inverter has thoroughly been tested with regard to various parameters of performance, power quality, islanding and reliability. The test results cope with the specification of the inverter and are competitive with other similar inverters.

Do inverters need to be tested?

This protocol has been adopted by the California Energy Commission (CEC) and any inverter used in a CEC approved PV system must be tested by an independent lab to this protocol. The CEC lists test results for thousands of inverters on its webpage. An example of a CEC test result is illustrated in the following figure.

How reliable is a prototype inverter?

Its performance has been evaluated for prototype inverters. In laboratory tests carried out, special concern was given to the subject of unintended islanding and safety parameters. The reliability of the inverter is assessed through highly accelerated life testing (HALT) and humidity tests.
