6 FAQs about [Photovoltaic inverter power testing 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 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.

What is a DC test for a solar PV system?

This standard also describes DC testing of the PV system, which can also be used for periodic testing of the system. In the standard, the test is classified into categories 1 and 2 according to the size of the PV system. Category 1 applies to all solar PV generation systems.

How can we verify the reliability of PV inverters?

To verify the reliability of PV inverters in diverse application scenarios, such as hot, cold, damp, high-altitude and offshore environments, a variety of extreme harsh environmental conditions can be simulated in our laboratory for testing and verification in accordance with IEC 60068-2 standards.

What is penetration testing in PV inverter?

Penetration testing provides a detailed overview of PV inverter security issues. The analysis is conducted by simulating a real hacker attack during the prototype development phase.

What is PV inverter research?

This research also develops models and methods to compute the losses of the power electronics switches and other components in a PV inverter. The losses are then used to estimate the junction and heat sink temperatures of the power semiconductors in the inverter.
