Out of my 3 Soyosource grid tie inverter, 2 had screen issues and had been changed. As these inverter are design to work 25 years or at least 10 years, the seller investigated how to modify it to have the screen totally switched off and still running. This is the result. We still dunno what will happened in the long run. We have been using this modification for 3 days, no issue. Hope this help someone.
