  "notes": "Source: evcc's charger implementation for the Compleo AC wallbox (charger/compleo.go), used as a secondary source -- it records the register numbers, the per-connector offset of 0x10, the unit ID 255 and the scaling of each row (power x100 W, currents /10 A, charged energy /10 kWh, voltages unchanged). Compleo publishes product and installation documentation for the Solo, but no register document is reachable without a partner login, so the supplier URL points at the vendor site and the map itself is evcc's hardware-tested definition. The wallbox is the Modbus TCP server on port 502. The global instructions live at the start of the address space (register 5 failsafe timeout, register 8 number of connectors) and the per-connector block starts at 0x0100 + 0x10 x (connector-1) for input registers and holding register 0x0100 + 0x10 x (connector-1); this file lists connector 1, which is the stand-alone case. Left out on purpose: the 32-bit charge duration at 0x0106, because evcc decodes that pair with a byte order that contradicts the big-endian decode used for every other multi-register value in the same implementation, so neither the word order nor the byte order can be cited for that row."
