6 FAQs about [Photovoltaic inverter quality identification form]

Why do solar PV system installers need to identify defective inverters?

This approach helps solar pv system installers to prevent time consuming problems when defective solar inverters are identified after arrival and cost-intensive installation.

How to verify a solar inverter certification?

After receiving the certifications, you can verify the authenticity of the certification on-line or check them (have them professionally checked) on-site. Certifications on your solar inverters provide the standards for the profitability and security of your investment.

What certifications does a solar inverter have?

Major important and common solar (pv) inverter certifications are IEC 61727, IEC 62103, IEC 62109, EN50438, AS4777, C10/C11, G38/1,G59/2, UTE-15712 and VDE0126-1-1. Basic solar inverter quality testing on-site at a factory includes a range of steps and tests.

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.

Are string inverters a good option for solar PV system?
