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.

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.

What is MPPT algorithm for photovoltaic inverters?

With respect to the photovoltaic inverter, already in 2006 Casadei et al. (2006) presented a MPPT algorithm based on the application of the “ripple correlation control” for single-stage converters that connects the photovoltaic installation to a single-phase grid.

Which inverter is required for a combined PV and storage system?

Combined PV and storage system topologies will generally require a bi-directional inverter, either as the primary inverter solution (DC-coupled) or in addition to the unidirectional PV inverters (AC-coupled).

Can field diagnostics improve inverter reliability?

This study combines a literature review with field diagnostics to better understand inverter failure modes, and to identify opportunities for improving inverter reliability and developing predictive maintenance practices for inverters.
