So my serial port died last night
i primarily use solar-assit, and it stopped updating during the night, i powered down the whole system,. put in the sunsynk dingle, powered back up, but no luck, its dead as this country. I have a 5kw Sunsynk, wonder if its possible just to buy that little serial board? its 4 screws and a cable not brain surgery to change, i really couldnt care if its a warranty item or not, just want the quickest path to fixing this
