Solar inverter obsolescence

4 FAQs about [Solar inverter obsolescence]

Why are string inverters becoming obsolete?

Older PV components fail to generate enough voltage to turn on and maintain the operation of the 1,000 V or 1,500 V replacement candidates, and many of the projects require grounding. Again, innovation creating obsolescence, as string inverters these days are ungrounded or “floating.”

Why is inverter reliability important in a large-scale PV plant?

Abstract: In large-scale PV plants, inverters have consistently been the leading cause of corrective maintenance and downtime. Improving inverter reliability is critical to increasing solar photovoltaic (PV) affordability and overall plant reliability.

Why is inverter reliability important?

Conferences > 2023 IEEE 50th Photovoltaic S... In large-scale PV plants, inverters have consistently been the leading cause of corrective maintenance and downtime. Improving inverter reliability is critical to increasing solar photovoltaic (PV) affordability and overall plant reliability.

Do inverters fail with age?

Things fail with age, whether they be cars, phones or inverters. Alencon, an optimizer manufacturing company out of Hatboro, Pennsylvania has published a white paper looking at the failure rate of central inverters used in aging 600 V solar plants. The inverters in question are five to 10 years old and are beginning to fail.
