### 5/5 — Wird immer besser

*2026-08-08*

Ich nutze die App seit vielen Jahren und habe festgestellt, dass die App in dieser Zeit kontinuierlich verbessert worden ist. Sie läuft sehr zuverlässig und nach den neuesten Updates auch immer übersichtlicher und informativer. Eigentlich ist eine zeitnahe Kontrolle der PV-Anlage ohne diese App nicht mehr denkbar.

### 4/5 — Größtenteils gute App

*2026-07-31*

Alle Daten sehr schön dargestellt und übersichtlich gestaltet.

Schade ist nur, dass der Graph unter Energie nicht direkt die aktuellen Daten anzeigt sondern ziemlich genau eine Stunde hinterherhinkt.

### 3/5 — Übersichtliche App mit ein paar Schwächen

*2026-07-24*

Die App ist übersichtlich gestaltet  und zeigt die meisten Infos vom WR an. Auch gibt es die Möglichkeit in die WR Verwaltung zu wechseln.  Leider ist es mir ein Rätsel wie man aus der App den Wechselrichter aktualisiert (Firmware) es wir angezeigt dass es ein Update gibt aber man kann es nicht imitieren. Außerdem stört in der Erzeugungsübersicht, dass die Umrechnung in km und l Warmwasser nicht aus dem Einspeisewert berechnet wird. Die umschließende Box suggeriert dies, es wird jedoch der Gesamterzeugungswert für die Berechnung herangezogen. Das ist leider irreführend.
Weiterhin ist es schade dass die Leistung nicht pro String erfasst wird.

### 1/5 — Never able to connect

*2026-07-23, version 4.0.0*

Unable to connect always spins in a circle after accepting conditions. Never works since I have an iPhone 16

### 1/5 — Doesn’t work

*2026-07-20, version 4.0.0*

I’ve been getting black out emails from fronius and no solar read out.  This app has been useless as it doesn’t work- it just gets stuck on the terms and conditions despite numerous times to download, Agree or accept them.  A bit over this.

### 1/5 — Not Working

*2026-07-17, version 4.0.0*

Authentication link won’t work! I have reloaded & renewed password. Nothing..

### 1/5 — App dead

*2026-07-10, version 4.0.0*

Can’t accept the terms, app won’t open.

### 1/5 — Terrible

*2026-07-06, version 4.0.0*

I recently installed a Fronius Wattpilot EV charger and the two apps don’t communicate with each other properly. At times Solar.web shows power flowing FROM my house yet I don’t have a battery, so that’s impossible. The household consumption data doesn’t get accounted for in real time so my EV will charge with power from the grid even though I have the Wattpilot set to only use surplus PV. Fronius should have ONE app only for all linked devices and then it may be better at providing useful graphics about what’s happening with your solar system. Tech support is terrible from Fronius Australia. Do better.

### 3/5 — Could be much better

*2026-07-04*

The app is stable and basic information is good. Appreciate the dark mode which is not available as yet on the Wattpilot app. But could be so much better. Please consider putting more battery controls inside the app for your reserva product rather than the web interface. Things such as I want the battery to charge from grid from x to x until full, or discharge this amount into grid between x and x. Also allow the user to specify how fast to charge when from grid when emergency charge button pressed rather than limiting it to 1.5kw.

### 1/5 — Repeated login

*2026-07-04, version 4.0.0*

You are forced to re-login everyday, often multiple times a time. Useless app if it cannot be readily and easily accessed.
