Unsere Technologie im Überblick
APsystems kombiniert eine hocheffiziente Leistungswandlung mit einer benutzerfreundlichen Überwachungsschnittstelle. Die Systemarchitektur ist darauf ausgelegt, die Energieernte zu verbessern und die Anlagenperformance transparent messbar zu machen – bis auf Modul- bzw. Mikrowechselrichter-Ebene.
Warum Mikrowechselrichter?
- Mehr Ertrag bei Verschattung: Leistungseinbußen wirken sich weniger stark auf die gesamte Anlage aus.
- Modul-/Geräte-Transparenz: Fehler und Abweichungen lassen sich schneller erkennen.
- Flexible Planung: Gut geeignet für komplexe Dächer (Ost/West, Gauben, Teilflächen).
- Einfache Erweiterbarkeit: Anlagen können oft schrittweise erweitert werden.
Monitoring & Kommunikation
Für die Datenerfassung und Anlagenüberwachung setzt APsystems auf Kommunikationsgateways (z. B. ECU/ECU-C). Das Gateway sammelt Leistungsdaten der Mikrowechselrichter und überträgt diese an eine Online-Plattform zur Auswertung und Visualisierung. So behalten Sie Ertrag, Status und Auffälligkeiten jederzeit im Blick.
Typische Anwendungen
- Wohngebäude: Einzelne Dachflächen, Verschattung, Ost/West-Layouts
- Gewerbe: Mehrere Teilgeneratoren, erweiterbare Anlagen, Monitoring-Anforderungen
- Carports & Nebengebäude: verteilt installierte PV-Flächen
- Modernisierung/Erweiterung: modulare Ergänzungen bestehender Systeme
Komponenten & Zubehör
Neben Mikrowechselrichtern umfasst das APsystems-Ökosystem auch passendes Zubehör – z. B. Kommunikationsgateways, Buskabel/Steckverbinder, Abdeck- und Endkappen, DC-Verlängerungen sowie Messtechnik für Messung/Regelung (je nach Systemkonzept).

FAQ – APsystems
Was ist der Vorteil von APsystems Mikrowechselrichtern gegenüber einem Stringwechselrichter?
Mikrowechselrichter arbeiten auf Modulebene. Das verbessert die Transparenz im Monitoring und kann Ertragseinbußen durch Verschattung oder unterschiedliche Modulausrichtungen reduzieren. Zudem sind Anlagen oft flexibel erweiterbar.
Wie funktioniert das Monitoring bei APsystems?
Ein Kommunikationsgateway (z. B. ECU/ECU-C) sammelt die Leistungsdaten der Mikrowechselrichter und überträgt sie an eine Monitoring-Plattform. So können Ertrag und Status zentral überwacht und Auffälligkeiten schneller erkannt werden.
Welche Rolle spielt das ECU-C Kommunikationsgateway?
Das ECU-C ist die zentrale Schnittstelle zwischen Mikrowechselrichtern und Monitoring. Es sammelt Daten, ermöglicht eine komfortable Systemübersicht und kann – je nach Systemauslegung – Mess-/Regelfunktionen unterstützen.
Für welche Anlagen eignet sich APsystems besonders?
APsystems ist besonders interessant für Anlagen mit mehreren Teilflächen, Ost/West-Dächern, Teilverschattung oder erhöhten Anforderungen an Transparenz und Fehlerdiagnose – sowohl im Privat- als auch im Gewerbebereich.
Was bedeutet „Kommunikation“ bei Mikrowechselrichter-Systemen?
Damit Monitoring und Diagnose funktionieren, müssen Mikrowechselrichter mit einem Gateway kommunizieren. Dafür kommen – je nach System – definierte Funk-/Datenverbindungen und passende Komponenten (Gateway, Antenne, Netzwerk) zum Einsatz.
Benötige ich spezielles Zubehör (Buskabel, Endkappen, Stecker)?
Ja, je nach Systemkonfiguration wird passendes AC-/DC-Zubehör benötigt (z. B. Buskabel, Abdeck- und Endkappen, Steckverbinder, Verlängerungen). Damit wird eine sichere, normgerechte und servicefreundliche Installation unterstützt.
Wie finde ich die passenden Komponenten für mein Projekt?
Entscheidend sind u. a. Netzform/Phasen, Layout, Kabelführung, Messkonzept und Monitoring-Anforderungen. Wir unterstützen Sie gerne bei der Auswahl der passenden APsystems Komponenten und des Zubehörs.
Wie hilft mir Monitoring im Servicefall?
Monitoring macht Abweichungen sichtbar (z. B. einzelne Geräte/Module mit Minderleistung). Das erleichtert Diagnose, reduziert Suchaufwand und kann Stillstandszeiten minimieren – besonders bei größeren Anlagen.
