ORT test of photovoltaic inverter

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.

Can a PV inverter be connected to a low voltage system?

This document is most applicable to large systems where PV inverters are connected to utility high voltage (HV) distribution systems. However, the applicable procedures may also be used for low voltage (LV) installations in locations where evolving OVRT requirements include such installations, e.g. single-phase or 3-phase 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.

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 does efficiency mean in a PV inverter?

Efficiency is the core index of the performance of a PV inverter; it is closely related to the power generation capability of the overall PV system. We provide customers with the most comprehensive efficiency testing services according to standards such as CEC, IEC 61683, IEC 62891, EN 50530, CGC/GF 035, etc.
