6 FAQs about [Photovoltaic inverter qualification rate standard]

What are motivation standards for photovoltaic (PV) systems?

Motivation Standards for qualification, reliability, and durability of balance-of-systems (BOS) components, such as power conversion equipment (PCE), for photovoltaic (PV) systems have trailed that of the PV modules. The efforts and approach for the qualification standards development have been mostly focused on the PV modules, rather than PCE.

What are the safety standards for PV power conversion equipment?

Safety standards The IEC 62109 series is the international safety standard for PV power conversion equipment. Part 1 is IEC 62109-1:2010, “Safety of Power Converters for Use in Photovoltaic Power Systems – General Requirements.”

What are the requirements for I-V measurement of photovoltaic devices?

Requirements for I-V measure- ment of photovoltaic devices are laid down in IEC 60904-1. IEC 61724-1 (2017): Photovoltaic system performance – Part 1: Monitoring This standard outlines equipment, methods, and terminology for performance monitoring and analysis of photovoltaic (PV) systems.

Are PV modules adapted for use in inverters safe?

Some tests applied to PV modules adapted for use in inverters are for mechanisms in PV modules, without a clear analog mechanism in inverters. Applied safety standards for PV inverters provide a rudimentary level of reliability testing, insofar as they relate to safety.

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.

What percentage of PV power plant service requests are based on inverters?

The inverters constitute between 43% and 70% of the PV power plant service requests as seen in Fig. 1. Financial losses additionally accrue due to energy losses. The inverter has been reported to be the greatest factor leading to energy outages, responsible for up to 36% of the energy loss .
