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.

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.

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 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.

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 happens if a micro-inverter is not used in a PV system?

If micro-inverters are not used, the PV system will have both AC and DC components. The DC system determines system power capacity and energy production, whereas the inverter and the AC system has the greatest impact on system reliability.
