Ratings and reviews

Initially the app worked then suddenly stopped working on my Android phone but worked on my android tablet. I contacted Fronius support at the end of Dec 2025 & after several emails plus multiple tries to download the solar.web app, a update has become available today 8/Jan/26. The app seems to be working satisfactorily now on both phone & tablet. Thank you for persisting to fix the problem & updating programming

It's been great but currently it's not working and that is why I came to see if there was an update and to check other reviews Had the company who installed it out today and he couldn't work out what was wrong. He did get it going but didn't know what he did to achieve that. Then after he left it stopped working again, probably coincidence that it happened to work while he was here.

I like the new separation of "generation" and "consumption" - it's much easier to glance at... But it does not display any actual content (it's blank for 4 days now). Energy tab shows no consumption at all for the week /month/year. Disappointing. The removal of the battery "storm charge" button is also disappointing. For a multi-billion, multinational - you can do better.
