APsystems ECU App Customer Insights

1. All the solar data is sent to their website where you log in to view it instead of doing the logical thing and integrating the exported data to the same login to be viewed from the app.An absolutely USELESS app.

2. I don't need to make other changes that are available on the pop-up form other than selecting the module that I want to view.The old version (2015) no longer accepting my username and password, so I uninstalled and installed this newer (2017) version.

3. Truly awful system.What's the point of this app? I have to connect directly to the ECUs wifi connection rather than via the internet, therefore I am no longer connected to the internet while viewing power info! Awful.

4. How come I can only manage it using wifi but it's connected using the LAN cable... I can't get this thing to upload data to APsystems.

5. The app even fails to sync the date and time with my phone--the most basic automatic function of every app in the 21st century! It won't accept a manual input for date and time either.

6. I can log in from my computer, everything is there, but now my phone is useless for monitoring my solar system.Cannot access system with app.

7. This app is for the installers to configure the system / microinverters, that's why you connect directly to the unit.

8. Absolutely nothing about this app works except the launch icon.Like the ability to track the performance of my solar installation.

9. Only the link on mobile browser actually shows data.

10. Even the provided link for doing it in browser doesnt work on desktop.

11. You really don't need this app once the little APsystems box is set up but to configure the box using this app... The worst app.
