Types of PV Inverters: Reliability Simulation for 3 kW Grid-Connected Systems in India

Narsapur, India, is the location for a dataset simulating the reliability of a 3 kW grid-connected photovoltaic inverter system. The data likely contains results from a Monte Carlo simulation with 10,000 samples, evaluating the B10 lifetime of inverters using different semiconductor technologies under a one-minute resolution yearly mission profile. Author Sainadh Singh Kshatri published the dataset on figshare under a CC-BY-4.0 license, with a last update in April 2026.

Use Cases

• Compare the B10 lifetime of conventional IGBT, SJ-M, SiC-M, and GaN-H based inverters based on the reliability analysis described.
• Model semiconductor switch lifetime using a two-parameter Weibull distribution based on the Monte Carlo simulation methodology.
• Analyze the impact of solar irradiance and ambient temperature on inverter performance based on the one-minute resolution mission profile data.
• Evaluate efficiency gains and loss reduction from wide-bandgap semiconductors based on the reported 40% loss elimination compared to IGBTs.

Strengths

• Includes simulation results for 10,000 samples with 5% parameter variation, providing a statistical basis for reliability analysis.
• Compares four distinct semiconductor technologies (IGBT, SJ-M, SiC-M, GaN-H) for a specific 3 kW PV inverter application.
• Based on a real-time mission profile for Narsapur, India, with one-minute resolution data for solar irradiance and ambient temperature.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small (5.5 KB), indicating limited scope, likely containing summary results rather than raw simulation data.
