Wechselrichter von SolarEdge in FHEM einbinden

Dieser Artikel beschreibt die Einbindung von SolarEdge Wechselrichtern der Serie SE(x)K in ein FHEM System über eine Ethernetverbindung mit Hilfe des Moduls ModbusAttr. Die Wechselrichter der SE(x)K Serie bis 10KWp (SE3K - SE10K) sind alle sehr ähnlich aufgebaut, so dass diese Anleitung für alle funktionieren sollte.

Vorbedingungen

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

Am Wechselrichter

Im zugehörigen Menü ist bereits der Port 502 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 60 192.168.178.36 TCP

attr SolarEdge userReadings AC-Power-Int-Use { sprintf("%.2f", ReadingsNum ('SolarEdge' ,'DC-Power',0) - ( ReadingsNum ('SolarEdge' ,'M_AC_POWER',0) + ReadingsNum ('SolarEdge' ,'B_Instantaneous_Power',0) ) )}
attr SolarEdge webCmdLabel {sprintf("AC-Energy %.3f",ReadingsVal("SolarEdge","AC-Energy",0));;;;}

danach können die Modbus Datenpunkte (Register) der vorhandenen SolarEdge Komponenten wie Wechselrichter, Zwischenzähler und Batteriespeicher wie folgt definiert werden.

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*.*
