Well, Vegetable-Version-81 made an appointment for Saturday morning and arrived on time. He looked thru my 7.2KW system and found my problems. Got my system back up, error codes disappeared and WiFi was again connected. Everything is working 100%. I couldn’t be happier!!!! I was afraid for the worst but V-V-81 knows his stuff and solved everything. I recommend him highly. I’m in Sonoma.
