6 FAQs about [Photovoltaic grid-connected inverter testing standards]
What is a photovoltaic inverter test?
Tests cover the inverter operation, performance and safety, the photovoltaic array installation, the system operation and applicable instrumentation. The tests described are suitable for inverter and/or system acceptance purposes or can be performed at any time for troubleshooting or to evaluate inverter/system performance and operation.
Why do you test & certify your inverters & converters?
We test and certify your inverters and converters with AC output, either grid connected or in stand-alone operations, according to local and international specifications and standards to ensure their safety, quality and compliance. Successful test results can lead to certification and the right to use our internationally recognized test mark.
What is an inverter certification test?
The inverter certification tests must also provide data to show maximum power tracking effectiveness, efficiency variations associated with power line voltage, environmental effects, and losses that occur at night and during protective shutdowns.
Which inverter is exempt from a utility voltage test?
Listed inverters with integral controllers are exempt from this test. Purpose: Verify the proper operation of the inverter under loss of utility condition. In this test, the time it takes for the inverter to disconnect from the ac grid after loss of utility voltage is determined.
What is an inverter control test?
The test will consist of demonstrating proper functional operation of the control and protective features. The majority of these tests are related to the inverter since most of the system operation and control is via the inverter. In some cases, devices external to the inverter will handle one or more of these features.
Are PV inverters safe and reliable?
As vital components of PV systems, PV inverters must be safe and reliable. PV inverters are critical components of PV power systems, and play a key role in ensuring the longevity and stability of such systems. The relevant standards ensure that your inverters perform safely, efficiently and with wide applicability.
