Hello,
I have an inverter Growatt mid 20ktl3-x vietnam version with jack with 4 pins for COM. I make the connection according the manual of the inverter but Eastron SDM630-MODBUS V3 does not want to communicate with the inverter. I changed the address to 002 on inverter and 002 on smart meter and nothing. I attached pictures. I tried all the possibilities where to fit the pins for connection and no success. I attached some pics.
