This report is available at no cost from the National Renewable Energy Laboratory (NREL) at www. . Photovoltaic inverter quality appraisa s and predict the reliability of PV inverters. Department of Energy (DOE) reports produced after 1991 and a growing number of pre-1991 documents are available free via www. Cover Photos by Dennis Schroeder:. . CSA 257 requires that any inverters used within a grid-connected PV installation be certified to CAN/CSA-C22. 1-01 (R2011) (denoted by CSA 107. 1 within this report as shorthand). 1 requires that an inverter has harmonic emissions below certain limits when the inverter is. . ssessing an inverter's longevity entails an examination of the manufacturer's proficiency and quality standards, which directly impact manufacturing processes, component durability, the inverter's resilience to common faults, and its performance during reliability tests. We found that one-third of the products we tested through our PV Inverter Product Quali-fication Program (PQP) failed key safety and performance tests – even though all of the tested products were. . PVEL conducted inverter reliability testing from 2014~2021, and released an Inverter Scorecard in 2019. While we no longer offer indoor inverter testing, we've kept that Scorecard accessible as we acknowledge that high-performing inverters are the key to profitable solar projects.
