In the realm of solar energy systems, the reliability of inverters plays a pivotal role in overall performance and sustainability. This solar inverter reliability study aims to clarify the comparative reliability of two prevalent inverter types used in solar installations: microinverters and string inverters.
With this in mind, this report showcases and describes an approach to help assess and predict the reliability of PV inverters. To predict reliability, thermal cycling is considered as a prominent stressor in the inverter system.
CONCLUSIONS In this paper, analytical equations were employed for computationally-efficient electro-thermal modelling of a PhotoVoltaic (PV) inverter. This resulted in significantly faster reliability modelling, which is suitable for iterative design and analysis of large-scale systems.
As a result, inverter reliability modelling is essential to benchmark the system performance and improve the design for higher reliability. However, traditional power electronic reliability modelling methods are mostly based on relibaity handbooks such as MIL-HDBK-217 .
Next, considering the mission profiles, reliability metrics of the inverter are extracted for a case study system. Afterwards, the system reliability performance is characterized in terms of input power, switching frequency,
