I have been using this app to manage a solar and EV system since 2022. I haven't an issue. There are some battery control improvements that would be good. I'd like the watt pilot functionality inside this app too, but my experience is good

I have connected my Fronius invertor via LAN cable to my router, now after downloading the solar web app, I can see and monitor the solar system. Syn my invertor data logger to the time zone is offset and has an issue. Overall, system mooting via the app is great.

Nice fresh UI update, please make an Android wear app!!! Not sure why the low reviews it's been fine for me and reliable, new update feature is welcome addition 👍

Terrible app! Stops working every time you have to update, which is weekly! Also, I have to pay to see data longer than 1 month old. Do better!

Normally pretty good but as of today you open app then it keeps closing it every time. Looks like fronius good at inverters but not at apps for the everyday user.

App will not open after new download from the store

Limited information available and not very robust, atm keeps failing to open. Fronius needs to lift their game with app support given their premium Inverter only has information available by app/software
