Reliability assessment of PV inverters

Mohamed Khalil, Payam Soulatiantork

Abstract

The target reliability levels of Photovoltaic inverters, that encounter Photovoltaic panels reliability, is a challenging issue. Currently a lot of efforts are carried out to improve the lifespan of photovoltaic inverter and reduce their outages. Special attention in this respect is given to the failure causes of inverters. In this paper, a complete FMECA analysis is presented to understand the root causes of these failures, estimate the local and final effects on generating energy, and recommended actions to avoid these failure modes. Additionally, an assignment of risk priority numbers is carefully considered to the each failure mode in order to prioritize the various hazards for a better maintenance strategies.
