Much improved

This app has been improved so much that I am satisfied with current version. It gives me the same information I can get from EMA website, including module performance, which is very helpful to identify a faulty microconverter. Good job!


Remember password?

I don’t know what happened with the latest update. Why would you remove persistent login? Now every time I have to re-enter login and password. Super annoying.


Decent app but needs a little work

The ability to monitor panel output and Microinverter performance would be greatly appreciated. Also, Microinverter and ECU software versions should be easily determined and also be easily upgradeable simply from this app.

If there's a problem with my system, the ability to create a 'ticket' via the app and have it sent to my installer and AP systems would be a great feature.

Tech-loving people like myself love data and being able to see system information. I understand the installers' app gives more detail. It would be nice if we could see some of that detail as well. I want to monitor my investment and make sure it's performing as it should.

Thanks for reading!!
