Heute können fast alle PV Wechselrichter das ModBUS TCP Protokoll. Nur wenige Hersteller von Wechselrichter machen das nicht. So auch der Kostal PIKO 5.5. Hier werden die Daten wie Spannung und Leitung nur auf dem Webinterface angezeigt.
Möchte oder muss man diese Daten aber mit andere Systeme verbinden, so muss man einen anderen Weg gehen. Im aktuellen Fall benötigt das NTUITY Energiemanagementsystem ausschließlich Modbus.
Ein Weg, um die Daten dem NTUITY Energiemanagementsystem aufzubereiten ist Node-RED. Node-RED bringt alle Module mit sich, um die Daten per Webabfrage abzuholen und dann über einen eignen Modbus Server zur Verfügung zu stellen.
Unten im Beitrag ist der Code dazu. Man muss nur das Passwort im „Kostal“ Webabfrage Modul reintragen und schon sollte der Modbus Server die Daten bereitstellen.
In diesem Beispiel werden die Daten auch noch an den ioBroker gesendet. Diese sind die blauen „Kostal“ Module. Wer die Daten für den ioBroker nicht benötigt, kann alle Kostal Module aus dem Flow herauslösen.
Zu Beachten ist, dass die unteren „Kostal L1 A“, „Kostal L2 A“ „Kostal L3 A“ Daten aus dem ioBroker kommen. Die Ampere werden in der Kostal Weboberfläche nicht angezeigt. Wir rechen hier im ioBroker per Skript die Watt und Volt auf Ampere zurück und übergeben sie dann wieder über Node-RED an den Modbus Server.
Man kann die Ampere auch direkt im Node-RED umrechnen. Vorausgesetzt, dass man die Ampere überhaupt benötigt.
Hier der Flow zum Importieren.

Der Kostal Piko Wechselrichter: Effiziente Energieerzeugung für PV-Anlagen
Photovoltaik (PV) ist eine nachhaltige und umweltfreundliche Möglichkeit, saubere Energie aus Sonnenlicht zu gewinnen. Um den erzeugten Gleichstrom in nutzbaren Wechselstrom umzuwandeln, sind Wechselrichter von entscheidender Bedeutung. Einer der führenden Wechselrichterhersteller in der Solarindustrie ist Kostal, und ihr Piko Wechselrichter hat sich als eine der bevorzugten Optionen für PV-Anlagen etabliert.
Die Grundlagen des Kostal Piko Wechselrichters
Der Kostal Piko Wechselrichter ist ein hochwertiges Gerät, das speziell für den Einsatz in PV-Anlagen entwickelt wurde. Er spielt eine entscheidende Rolle bei der Umwandlung des von den Solarpanels erzeugten Gleichstroms in den Wechselstrom, der in Haushalten und Unternehmen genutzt wird. Die Piko-Wechselrichter von Kostal sind bekannt für ihre Effizienz, Leistungsfähigkeit und Zuverlässigkeit.
Effiziente Energieumwandlung
Der Schlüssel zur Effizienz von PV-Anlagen liegt in der Fähigkeit des Wechselrichters, den maximal erzeugten Gleichstrom in nutzbaren Wechselstrom umzuwandeln. Der Kostal Piko Wechselrichter zeichnet sich durch einen hohen Wirkungsgrad aus, der sicherstellt, dass möglichst wenig Energie während der Umwandlung verloren geht. Dies trägt dazu bei, den Gesamtertrag der PV-Anlage zu maximieren und die Energiekosten zu senken.
Leistung und Skalierbarkeit
Die Kostal Piko Wechselrichter sind in verschiedenen Leistungsklassen erhältlich, um den unterschiedlichen Anforderungen von PV-Anlagen gerecht zu werden. Von kleinen Wohnanlagen bis hin zu großen gewerblichen Installationen können Anwender den Wechselrichter auswählen, der am besten zu ihrer spezifischen Anwendung passt. Die Möglichkeit zur Skalierung ist ein großer Vorteil, da PV-Anlagen je nach Bedarf erweitert werden können.
Zuverlässigkeit und langlebige Qualität
Die Zuverlässigkeit eines Wechselrichters ist von entscheidender Bedeutung, da er über viele Jahre hinweg kontinuierlich arbeiten muss. Kostal ist für die Qualität seiner Produkte bekannt, und der Piko Wechselrichter bildet hier keine Ausnahme. Er ist robust und langlebig, was sicherstellt, dass die PV-Anlage über viele Jahre hinweg zuverlässig und ohne größere Störungen arbeitet.
Überwachung und Fernzugriff
Der Kostal Piko Wechselrichter bietet oft die Möglichkeit zur Überwachung und Fernzugriff. Das bedeutet, dass Anwender den Status ihrer PV-Anlage in Echtzeit überwachen können. Dies ist besonders nützlich, um Leistungsprobleme oder Ausfälle schnell zu erkennen und Maßnahmen zur Behebung zu ergreifen.
Umweltfreundliche Energieerzeugung
PV-Anlagen, die mit Kostal Piko Wechselrichtern ausgestattet sind, tragen zur Reduzierung der CO2-Emissionen bei und leisten einen Beitrag zur nachhaltigen Energieerzeugung. Die Nutzung von Solarenergie hilft, die Abhängigkeit von fossilen Brennstoffen zu verringern und den ökologischen Fußabdruck zu minimieren.
Insgesamt bietet der Kostal Piko Wechselrichter eine zuverlässige und effiziente Lösung für die Umwandlung von Sonnenenergie in nutzbare Elektrizität. Mit seinen vielfältigen Leistungsklassen und der nachhaltigen Energieerzeugung ist er eine beliebte Wahl für PV-Anlagen in Wohn- und Gewerbegebieten.
