What people report
SunSpec over Modbus works for standard inverters; the E3DC S10 failed to set up and the Aurora/APsystems ECU-R only exposes per-inverter data.
- Partly works1
- Not working1

| APsystems ECU-R-PRO | Partly works Local | Reports per-inverter data only; no separate panel readings over RS-485 ModbusSaved copyECU-R exposes the data of the inverters, not the separate panels on its RS-485/modbus interface. However, it does expose the inverters twice, once with integer data + scale factors in model 101/102/103 (single/split/multi phase), once as floats (Sunspec models 111/112/113). I only have one inverter, so I don't know if each inverter shows up separately, or if it's all added up by the ECU-R into one big "model" object.
