I have struggled to get stable communication between my Growatt SPF inverters and Solar Assistant running on Orange PI. It works at times but get frequent CRC errors. I have tried different cables, purchased cables with ferrite chokes, re routed cables, wrapped them in foil, etc. Sometime I can connect but typically not long. Got even worse after most recent firmware update of SA.
I can communicate with the inverters via my PC using the exact same cables, and the inverters communicate no problem with Growatt Shineserver via the wifi dongle.
Looking for suggestions on other possible fixes. Perhaps grounding the chassis of the Growatts? I looked but did not see a chassis ground point.
