SE10k von Solaredge in FHEM einbinden

Dieser Artikel beschreibt die Einbindung eines Solaredgewechselrichters SE10k in ein FHEM System über eine Ethernetverbindung mit Hilfe des Moduls ModbusAttr.

Vorbedingungen

FHEM läuft und hat genügend Platz für Modifikationen und Logfiles (ca. 100 MByte / Jahr).

Am Wechselrichter

Im zugehörigen Menu ist bereits der Port 503 eingestellt. Trotzdem muss dieser noch einmal aktiviert werden, da sonst Modbus TCP nicht aktiv wird. Hilfe da zu bietet die Installationsanleitung [1]. Es ist möglich, dass es auch nur 10 Minuten aktiv bleibt wenn er nicht angesprochen wird.

ModbusAttr Device in FHEM

in FHEM wird ein ModbusAttr angelegt

define SolarEdge ModbusAttr 1 30 192.168.178.36 TCP

danach alle Attribute aus dem unten stehenden list nach dem Verfahren: attr SolarEdge dev-h-defPoll 1

Mehr Daten sind im Sunspec Protokoll [2] zu finden

Log

Das ModbusDevice legt sich ein eigenes Log an. Um aber übersichtliche Grafiken zu bekommen werden die Daten des Dummy benötigt. Hier hilft ein Logfile

define FileLog_KePv Filelog %L/pv-%Y.log dum_pv*.*
