### 5/5 — Aufgeräumte Oberfläche, neuer Arbeitsmodus ist super praktisch

*2026-06-16*

Diese neue App-Version hat eine aufgeräumte und ansprechende Benutzeroberfläche. Der neu hinzugefügte Arbeitsmodus ist total einfach zu bedienen – klare Empfehlung!

### 1/5 — Appli pourrie

*2025-10-14, version 1.0.11*

Application qui ne fonctionne pas !!! Impossible de connaître la production ni même de savoir si les panneaux fonctionnent correctement. À quoi sert elle ???

### 5/5 — Läuft bei mir

*2025-10-01, version 1.0.11*

Einrichtung und Installation war einfach. Läuft bei mir. Bis jetzt keine Klagen. Wenn ich mir die anderen Rezensionen hier so angucke, bin ich gespannt, was noch  passiert.

### 1/5 — Fuyez

*2025-09-21, version 1.0.11*

L’application est pleine de bug : la configuration des micro-onduleurs est capricieuse (réussi en mode utilisateur finale mais impossible en mode installateur), l’ajout du compteur TSUN Smart Meter changé le type de centrale : impossible d’obtenir les informations de consommation et d’injection via le tableau de bord.

Il y a du boulot pour proposer une vrai expérience… très loin de certains concurrents.

### 2/5 — Übersichtlich nicht Stabil.

*2025-09-17, version 1.0.11*

Leider fehlen an manchen Tagen die kompletten Erträge aufgrund von Unterbrechungen in der Verbindung. Solche Laienhafte Fehler sollten in der heutigen Zeit nicht mehr vorkommen. Wenn behoben und läuft gibt es mehr Sterne.

### 2/5 — TSUN

*2025-09-01, version 1.0.11*

Simple à mettre en place avec les numéros de série/BQ de problèmes depuis une update 2025. Puissance crête de la journée a disparue/Production instantanée ne l'est pas et semble parfois figée, je produis bq plus que ce qui est indiqué (j'ai un Ecojoko)/Synchro de l’acquisition semble décalée car j'ai des panneaux avec une grosse différence de production alors qu'ils sont sur la même face de toiture/Très mauvaise pub pour MonKitSolaire alors que les panneaux et onduleurs semblent de bonne qualité

### 2/5 — Demora na atualização de dados

*2025-08-15, version 1.0.9*

Parece que os microinversores MP2000 somente enviam dados a cada 15min. Poderiam atualizar sob demanda (deslocando a tela do app para baixo)

### 1/5 — Suboptimal

*2025-08-02, version 1.0.9*

Nahezu untauglich, diese App für den TSun Wechselrichter ist in China entwickelt worten, in der deutschen Sprache ist sie nicht zu gebrauchen. Da wird das englische "Save" , um eine Änderung zu speichern, um nur einen der vielen Übersetzungsfehler zu nennen, mit "Sparen" übersetzt. Unglaublicher Blödsinn. Die wichtigsten Dinge funktionieren nur, indem der User auf Englisch umschaltet.
Eigentlich eine vollkommen sinnlose App, hier müssen die Entwickler noch mächtig daran arbeiten.

### 2/5 — Gros problème d’acquisition

*2025-07-31, version 1.0.9*

Délai parfois 30 min et 15 min en std , des points sur le graphe qui s’affichent en décalés 
Si plusieurs modules micro onduleur, la synchro de l’acquisition semble décalé car j’ai un groupe à 300w et l’autre a peine à 100w alors que sur même face de toiture

### 4/5 — Wieder besser

*2025-07-17, version 1.0.9*

Seit dem aktuellen Update ist die Startansicht deutlich übersichtlicher gestaltet und auch die Tages-Aufzeichnungen funktionieren. 
An der Performance könnte man noch etwas schrauben … die App ist noch etwas langsam.

Außerdem ein großer Punkt der mir fehlt: wieso kann ich in der Tages oder Monatsansicht nicht mehr sehen, wie hoch der Peak exakt war und wieso erkenne ich nirgends wie viel Strom in den letzten Tagen erzeugt wurde?
