What's New in EMA App

9.0.3

September 6, 2026

Some optimizations and improvements.

User reviews

Broken

The new update (Sep/2026) has broken part of the app. I see real time info, but get “data receiving failed “ for any attempt at looking at the “apems” tab. Please roll back the update, it wasn’t broken and worked fine before.

The new update is awful.

Latest Upgrade is a Downgrade

Not sure what problem they were trying to address with the latest upgrade but they made some bad choices.

You now need extra clicks to get to day/daily/monthly/yearly graphs. The graphs are now more poorly represented, are smaller and no longer switch to landscape on a phone.

Pretty poor upgrade since the graphs were the most important features for home users.

You made it worse

Why are companies obsessed with AI slop and trying to make everything “AI”? This app is so much worse since you “upgraded it”. The old app was simple, utilitarian and easy to use. I used it everyday, multiple times a day. The new one I go days without looking at because finding the information I want is so awkward and frustrating that I can’t be bothered. I will just uninstall it and only download it again it my system has a problem, hopefully you have gone back to the a simpler system again by then.

This update is complete garbage

My customers are calling me to ask what happened to the app. AP Systems used to have the best app in the industry and now with this “update” it’s the worst by far. Things are slow and delayed, you have to click more to see different ecu’s and module views. There is a fancy smooth curve for power generation but you can’t see it a clearly as it was before. Might be time to switch inverter companies.

The old app was better

The new and improved app no longer shows individual panel output and also missing is the daily, monthly, and yearly average graphs. The new app is a big disappointment. I wish I hadn’t updated!
