Every measurement is an integer paired with a signed power-of-ten scale-factor register. This map covers identity and the 16-bit inverter AC/DC measurements, operating state and the 16-bit vendor status code, plus meter 1 currents, voltages, frequency and power; 32-bit registers are left out because the note contradicts itself on their word order.",

  "All registers are read with function 03; the note describes this SunSpec map as read-only monitoring data.",
  "Value = raw x 10^SF, where SF is the signed int16 named in scale_factor_ref. Read a value and its SF in the same request so they belong to the same sample.",
  "Word order: the meter section of the note says registers are big-endian with the most significant part first, but Appendix A states, for communicating with SolarEdge devices in general, that 32-bit values use little-endian word order (with a big-endian copy at +0x800). The appendix does not limit that statement to the proprietary registers, so every 32-bit register is left out: C_SunSpec_ID 40000, I_AC_Energy_WH 40093, I_Status_Vendor4 40119, meter 1 real-energy counters 40226-40240, apparent-energy totals 40243/40251 and M_Events 40293. Their scale-factor registers (40095, 40242, 40259) are kept.",
  "I_AC_Energy_WH_SF (40095) is typed uint16 in this note although SunSpec scale factors are signed int16; the published type is kept. Its energy register is not listed (see word order).",
  "The note attaches a footnote to I_AC_VoltageAN/BN/CN reading 'Supported only in split-phase configurations'; the same footnote marker also appears on the status table. These registers may be unimplemented on some grid setups.",
  "On the inverter table the footnote 'use this field for versions up to 3.19.XX' is attached to I_Status_Vendor (40108) and also to I_AC_PF and I_AC_PF_SF (40091-40092).",
  "Left out: Multiple MPPT extension model 160 (from 40121, Synergy three-phase inverters only, firmware 4.13+). On Synergy units it occupies the addresses where meter 1 sits on other inverters, and the meter blocks move by +50 (2-unit) or +70 (3-unit).",
  "Left out: meter line-to-line voltages 40199-40202 (the note says SolarEdge meters do not report L-L voltage over SunSpec), per-phase meter VA/var/PF, per-phase apparent energies and the reactive-energy quadrant counters 40260-40292.",
  "Meters 2 and 3 repeat the meter 1 layout at base 40295 and 40469 (base 0, default). Only enabled meters are readable and they are packed in order, so if meters 1 and 3 are enabled, meter 3 appears in the meter 2 slot.",
  "The meter overview text mentions DID 4 or 5, while the register table lists 201-204; the table values are used here.",
  "Active/reactive power control (curtailment) is documented in SolarEdge's separate Power Control document and is not part of this map."
