Notes
SolarEdge inverters speak SunSpec Modbus TCP on port 502, unit ID 1. Modbus TCP must be enabled with SetApp (Communication -> LAN -> Modbus TCP) or, on inverters with an LCD, from the Communication menu; only one Modbus leader may talk to the inverter at a time, and SolarEdge recommends keeping the monitoring connection in parallel. The SunSpec map starts at base address 40000: common model at 40000, inverter model 101/102/103 at 40069 and, when an energy meter is installed, the meter's own common block at 40121 and its meter model 201-204 at 40188. A second and third meter follow at 40295 and 40469 (add 50 registers for 2-unit and 70 for 3-unit Synergy inverters). SolarEdge uses the integer-with-scale-factor (int+SF) models, so every measurement has a paired scale factor register: engineering value = raw x 10^SF, and the scale factors are chosen by the inverter rather than fixed. Reading a meter requires the meter to be enabled; the meter type is in the meter model ID. The vendor power control registers at 61441/61696 are only meaningful with a grid-code configuration and are documented in SolarEdge's power control application note, not in the SunSpec document. Points the inverter does not implement read as 0xFFFF (uint16, enum16), 0x8000 (int16) or 0xFFFFFFFF (acc32), so filter those values. Addresses are the base-0 (wire) addresses of the technical note.
