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.

Not sure how to answer this but that is one BIG inverter. Very impressive.
 
In case someone runs across this the op got it working :

I solved the issue with the communication between Growatt Mid 20ktl3-x Vietnam version(China version) through an installer which from Growatt Installer App, entered on my inverter remotely and modify the registry and open the communication between Inverter and Smart meter. The inverters sold on Asian market, most of them are only for injection and the communication with a smart meter is disabled from the software. Now everything is working perfectly.
