Common faults discussed include panel degradation, electrical issues, inverter failures, and grid disturbances, all of which affect system efficiency and safety. While traditional diagnostics like thermal imaging and V-I curve analysis offer valuable insights, they mostly detect. . Abstract— This paper presents two methods of detecting inverter downtime and estimating lost production from downtime events using timeseries system production measurements. The methods focus on distinguishing communications interruptions from true production outages and are successful in most. . With the rising adoption of solar power globally, maintaining system reliability and performance is vital for a sustainable energy supply. . Inverters are the most failure-prone component in solar systems, with 45% experiencing failures within the first 4 years of operation according to LBNL's 2024 inverter reliability study. This represents billions in lost revenue and emergency replacement costs globally. Unscheduled downtime due to error codes remains the single largest non-financial risk to PV project Internal Rates of Return (IRR).
