This app is awful, just trying to reset the password is an epic journey that doesn't end and to top it off, support want to charge $275 to come out and fix my problem. My inverters aren't on the cloud and trying to connect is terrible. You need to make the app more user friendly, a zero rating is what this app deserves.

Not a very good app. I can get it to connect to the inverter using its own wifi SSID (local monitoring), which provides basic information about system performance. I spent almost an hour trying to set up remote monitoring, without success. It hangs up frequently and doesn't tell you what (if anything) is wrong.
