Thanks for the extra details. Can you also screenshot the meter rs485 configuration page in setapp?

So the hunch I have is that this is related to the synergy tech in your larger inverters, which causes meter registers to be shifted by 50 in the register...

Bah! You're sure the meter (and the script) does work when connected to the SE10k inverter, right?

Ok, tut mir leid, I didn't completely read the documentation. You have three units coupled together, which according to the sunspec docs require an offset of 70, not 50. Could...

Do you have SetApp access to the two non-display inverters? In the commisioning menu you can view `Site Communication` -> `RS485-1` and `RS485-2` -> `Device ID`. Your inverters should be...

Thanks for reporting this. If you modify [`solaredge_modbus/__init__.py` line 403](https://github.com/nmakel/solaredge_modbus/blob/22ad232971329f67b6f647f0513a87e033fd78e9/src/solaredge_modbus/__init__.py#L403) to read `self.wordorder = Endian.Little`, does that resolve the `cosphi` issue? Ignoring for a second that all the other values...
