### 1/5 — Doesn’t save my inverter serial number

*2025-01-09, version 2.11*

Who wants to be entering their serial number into app everytime they open the app? Needs a password so you would think once entered it would be saved. Useless app

### 1/5 — Very poor app

*2024-12-17, version 2.11*

Extremely slow, few features , often connection times out. Feels like the app was made by a high school student who failed comp sci.

### 1/5 — Terrible app

*2024-11-29, version 2.11*

Delta have built an app that feels like it is 10 years out of date.

It often freezes up after you sign in. You have to close and reopen the app multiple times to get it to work. The user experience is really frustrating.

It’s really unreliable!

### 1/5 — Terrible app

*2024-08-29*

Delta have built an app that feels like it is 10 years out of date.

### 1/5 — Activation Key Needed

*2024-05-02*

I downloaded this app and it is free.
However, I could not use it because it asks for Activation Key and there are none to be found. Rendering this app useless.
It lists app key but needs an activation key for it to work.

### 1/5 — A rubbish app

*2024-04-25, version 2.10*

This inverter replaced a 12 year old inverter from a different brand.
The app on the old system was far superior to this. Surely 12 years later they would be capable of producing a more user friendly app than this. Extremely disappointing!

### 1/5 — Schlechte App

*2024-03-29, version 2.10*

Dem kann ich mich nur anschließen

### 1/5 — Poorly developed app

*2024-02-15, version 2.10*

The app is remarkably slow. It’s slow to refresh. You often have to close the app down just to get data updates. It’s unbelievably hard to connect to an inverter it’s actually not even funny. In this day in age these things should be very streamlined. Very disappointed.

### 1/5 — Unbrauchbarer Müll

*2024-02-08, version 2.10*

Kauft euch ja keine Geräte von Delta außer ihr könnt chinesisch! App ist absolut unlogisch und dermaßen kompliziert, da steigt kein Mensch durch! 
Kauft euch anständige deutsche Geräte von deutschen Herstellern!!!

### 1/5 — Unfassbar schlecht

*2023-12-17, version 2.8*

Was um Himmels Willen hat sich der Hersteller mit dieser App gedacht?
Mal davon abgesehen das der Wechselrichter funktioniert, war das Einrichten dieses ein Marathon. Die einzelnen Schritte der Inbetriebnahme waren überhaupt nicht erklärt. Am Ende war es wahrscheinlich einfach nur Glück das diese nach unzähligen Versuchen überhaupt geklappt hat.
Die Reihenfolge der IBN Steps sind in unlogischer Reihenfolge, in verschiedenen Sprachen und nicht erklärt.

Letztlich ist die App völlig unbrauchbar. Eine lokale Verbindung zum Wechselrichter war nach wenigen Tagen nicht mehr möglich. Zuvor mussten immer Handy oder Tablet neu gestartet werden, erst dann konnte man sich lokal Verbinden. Inzwischen geht es wie gesagt garnicht mehr. Über „entfernt“ kann man sich zwar verbinden, jedoch kann man hier nur erkennen ob der Wechselrichter überhaupt noch am arbeiten ist. Und an welchen Tagen wieviel produziert wurde.

Die App ist dermaßen schlecht aufgebaut, langsam, nicht verständlich und unnütz, dass sie eigentlich eine Beleidigung für den Hersteller ist. Jeder zweitägige Computer Kurs an einer Volkshochschule hätte eine bessere App hingeschissen.
