 "notes": [
  "Register table comes from Fronius' official XLSX in the 'Modbus Sunspec Maps, State Codes and Events' ZIP (same download page as the PDF); behaviour and settings come from the PDF.",
  "All addresses here assume SunSpec Model Type = int+SF. With the default float setting the inverter model is 111-113 and every later model starts 10 registers higher (e.g. nameplate 40131 instead of 40121).",
  "Fronius warns the map is dynamic: the correct method is to walk the SunSpec model chain from 40001 (ID, L) and use offsets. The fixed addresses below are the published layout for a single inverter.",
  "Word order: neither the PDF nor the XLSX states the order of 32/64-bit values, so every 32/64-bit register is left out: SID 40001-40002, WH lifetime energy 40094-40095, Evt1/Evt2/EvtVnd1-4 40110-40121, ActWh 40187-40190, StActCtl 40217-40218, Tms 40223-40224, model 160 Evt/DCWH/Tms, and site totals F_Site_Power/Energy 500-513. The SID is documented as 0x53756E53 'SunS', which suggests high word first, but this is not stated.",
  "Registers marked 'Not supported' in the XLSX are left out (temperatures, VMax/VMin, quadrant 2/3 ratings, ride-through, Ris, StorAval, InBatV, and similar).",
  "Unsupported values read as: int16 0x8000, uint16/enum16/bitfield16 0xFFFF, sunssf 0x8000. Some 'supported' points also return these, e.g. phase B/C on single-phase inverters, DCA/DCV on multi-input inverters (use model 160).",
  "The XLSX notes that WH (lifetime energy) may be imprecise; ActWh in model 122 is the alternative (both 32/64-bit, omitted here).",
  "Access is taken from the XLSX R/W column. VAMax (40157) and WMaxLimPct_RmpTms (40236) are marked RW but list only function code 0x03; the PDF says writes to unsupported RmpTms are ignored (ramp supported from Datamanager 3.13.3-2 / Hybridmanager 1.11.3-2).",
  "Model 124 (storage) is only meaningful on Fronius Symo Hybrid with battery.",
  "The PDF describes PVConn bit 1 as 'responsive'; the XLSX calls it 'Available'. The XLSX wording is used.",
  "Energy meters (Fronius Smart Meter) are published at unit ID 240-244 with their own common block and meter model 201-203 starting again at 40001; they are not part of this inverter map."
