6 FAQs about [Inverter maintenance for photovoltaic power plants]

Why is maintenance management important for PV power plants?

Therefore, maintenance management is essential for reliable and effective operation of PV power plants, ensuring uninterrupted system operation and minimizing downtime. Compared to well-established technologies such as hydro, thermal, and wind, the O&M processes for PV systems are not yet fully structured in many operating companies .

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).

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.

Do photovoltaic systems need maintenance?

The expansion of photovoltaic systems emphasizes the crucial requirement for effective operations and maintenance, drawing insights from advanced maintenance approaches evident in the wind industry. This review systematically explores the existing literature on the management of photovoltaic operation and maintenance.

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 a good corrective maintenance plan for PV power plants?

One important aspect of a good corrective maintenance plan for PV power plants is ensuring that spare parts are available and accessible when needed to avoid prolonged plant down-time/outage due to equipment malfunctioning or damage.
