Tested the flow cards for my Growatt, they’re not working 
These are the values read from the inverter, seeing some weird values there:
I found a document online Growatt Inverter Modbus RTU Protocol_II V1.05 2018-04-19 and used that in combination with the Modbus app by Ronny Winkler ([APP][Pro] Modbus) to retrieve some values but I can’t say I get something useful/readable (But that’s probably me not familiar with the Modbus protocol)
I can read register 3, that returns 100 and register 4 which returns 255
Register 9,10 and 11 return 17483, 12950 and 12333
Register 88 returns 0
This is one of the flows:
I’m wondering if my inverter is using the Protocol_II or maybe an older version…
No idea how to proceed from here, any tips or things you need me to check @Edwin_Biemond?
