The QC Solar QC4.10 product specification prints "The connector is considered to be in compliance with UL 6703, Connectors for Use in Photovoltaic Systems, Edition 1" only when assembled as its instructions specify, and lists the UL certified model as "QC4.10-a5CDEf1g1". The UL certificate page in the file is an image with no text layer and was not read; no UL directory record was read.
QC Solar (Suzhou) Corporation product specification for the QC4.10 (PLUS, one-piece pin) PV connector, authored by QC Solar. This copy is hosted by Best Solar Bundle on its own Shopify file host (bestsolarbundle.com/cdn/shop/files) and is linked from the Data Sheet tab of the Best Solar Bundle kit pages that include the part, captured on September 25, 2026. It describes the component, not the kit: it establishes what QC Solar publishes for that part and says nothing about the kit's total figures or kit warranty. The bill of materials page prints issue date 2022.08.11. The TUV and UL certificate pages at the end are images with no text layer and were not read. The file is also linked from Best Solar Bundle's own "QC4.10 Connector" page.
