Comments on KOSTAL Solar App for Android

★★★★☆ Charalampis Vegkos · May 13, 2022

Hello. After the last update, the inverters / strings are no longer visible in the Last Data section, only the total / combined yield. The display of each inverter / string of the plant, is very important, as it gives you a direct view of their status. Another issue present and in the previous update (and still exists in the current) is that the yield in the Last Data section, is MW (!!!), not kW. In the History section is correct. Thank you.

★★★★☆ Guy Middleton · Aug 25, 2020

Postal have fixed the data issue, so it is now up-to-date all the time. Aside from a couple of issues (see below), everything about the app itself is excellent. There are really nice charts to see generation, usage and feed-in in different ways. There are two remaining issues which need fixing for a nice customer experience: 1) The app loses the login details fairly frequently, maybe every week or two. The app should be updated to never lose the login information. 2) If you enter the wrong password the app says 'Connection error' so some people may not realize the password was wrong. The app should be updated to say that the username or password were not recognized.

★★★★☆ Bjørn Olsen · Feb 3, 2024

The app is slowly getting up to speed after their overhaul. Only current problems are that the graph resolution cannot be changed and that the "Plant installed power" field is labeled as kWp but actually is Wp.

★☆☆☆☆ Dimitri Philippe · Oct 13, 2023

Cannot give 0. After years, the app still does not fetch and display data. Must use the user unfriendly web server functionality to access data.

★☆☆☆☆ Michael J. Korsholm · May 21, 2025

The app is useless, It's not showing the grid draw only what has been used from the battery and direct consumption. To get the information I have to use the kostal-solar-portal.

★☆☆☆☆ Constantinos Kyriacopoulos · Feb 6, 2024

After what was described as maintenance and upgrade the app will not let me log in and will not recognize my email. No credible support in solving the issue.
