Ratings and reviews

Pretty poor user interface and you only get 3 days of data unless you pay for the Premium option. The Month and Year display does not work properly. Considering the cost of the Inverter and NO actual display on the unit, you're compelled to use an App to get data. Expected better from a reputable company.

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

No matter what i try the live data overview page does not show any info, very frustrating. Shows "data transfer interrupted"... I've updated all firmware that I can. Other features work and my battery app works fine. used to work fine until the last few weeks.
