I described my problem in a previous message. Here we go again today. Doesn't even want to turn on the sockets... It's not only switched off AC, but also don't want turn on AC in UPS mode. It's not working without AmpUP, wih AmpUP, with SOC 100%, 90%, 80%, power charging on 1200, 800, 500 etc. I have been trying all combinations, but I think it is a problem with a firmware. I can hardly start АС the tenth time or more. This is hell! Support, please help me!
