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 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.

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 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.

Do photovoltaic modules need a certification test protocol?

A certification test protocol that delivers an accurate and credible estimate of component and system performance is needed. Even with current component qualification information, photovoltaic module performance data must be modified to account for actual conditions.

How do you operate a photovoltaic inverter?

Verify the operation of the systems local control functions. Start with the inverter in shutdown mode. Ensure that the photovoltaic array is connected and operational, that there is sufficient sunlight to operate the inverter, and that the ac and dc contactors and disconnects are closed.
