  "notes": "MIRROR-SOURCED. Source: Alpitronic \"Hypercharger - Load management manual\", version 2-3, chapter 3 \"Modbus TCP server\" (Tables 10-13) for the HYC50/150/200/300/400 Hypercharger DC chargers. The vendor's download portal (doc.hypercharger.it) sits behind a partner login, so the manual was read from the copy in the Gekko device library (https://devicelib.my-gekko.com/download_docu.php?id_pk=292&ext=pdf&fname=EN_HYC_XX_MAN_Load+management+manual+Software+version+2.3.x.pdf), which is the file the SHA-256 below belongs to. BayWa r.e.'s SolarShop copy serves the older 'hypercharger - LoadManagement' version 1-17 instead (no connector-0 VAR registers 49/51 or connector-0 SetReactivePower at holding 2, SoC %/10), so it is not the source of these rows. The manual states port 502, big-endian byte order (the lower address holds the most significant byte) and function codes 3, 4 and 16. Input registers 0-51 describe the station; per-connector input registers use the first address digit for the connector (1xx = connector 1, 2xx = connector 2, 3xx = connector 3, 4xx = connector 4) and connector 1 is transcribed here. Holding registers 0 and 100 set the active power limit, 2 and 102 the target reactive power. The manual documents no unit identifier, so unit 1 is a placeholder. Left out: connector registers X14/X16 (deprecated VAR duplicates of registers 49/51) and X32 (INT64 total charged energy, a type the app does not have). Writing holding registers requires the configuration key ModbusLoadManagementEnabled; the server itself is enabled by default. File identity: SHA-256 f81911c3effe34d22d3b89dbdc0ba5b934f77851da749f0d8e0dca3f290b8f3c (PDF, downloaded 2026-11-07). The mirror is used only because the vendor publishes this load-management manual to partners rather than on its public portal; the document itself is Alpitronic's own, titled \"Hypercharger - Load management manual\", version 2-3."
