Hello Pastelina, may I kindly ask you for the picture of motherboard so that I could localize capacitor please? I have the same issue on my MAX 11 inverter. Thanks
Dear Burleanu many thanks for your posts.
I'm also fighting with esp8266/32 communication for Home Assistant with SMG II inverters.
May I kindly ask you to share just shortly how you can flash wifi dongle delivered with SMG II inverter with tasmota firmware?
Many thanks
