Solaranlage Komplettbeispiel Fronius BYD

An dieser Seite wird momentan noch gearbeitet.

Einbindung eines Fronius-Wechselrichters, BYD-Speicher, SolarForecast, evcc-Autoladen und FTUI 2 Darstellung in FHEM

Dies Wiki beschreibt die beispielhafte Einbindung einer Solaranlage in FHEM.

Alle Module zur Steuerung der Komponenten sind bereits in fhem vorhanden bzw. werden gerade weiterentwickelt.

Ein Wechselrichter der Fa Fronius aus Österreich sowie der beliebte China-Speicher von BYD sind oft die Grundeinheiten einer Einfamilienhauslösung.

Alle notwendigen Readings werden über die vorhandenen Module speziell für dies Paket über Userreadings erzeugt,

so das auch andere Erzeuger oder Speicher in das Grundkonstrukt übernommen werden können.

Vorbedingungen

FHEM läuft und hat genügend Platz für Logdaten (>1GB/Jahr)

Der Wechselrichter sowie der Speicher sind über Lan oder eine sehr stabile(!) Wlan Verbindung erreichbar.

Von Wlan ist aber abzuraten, weil diese Verbindungen oftmals zu lange Zeitverzögerungen oder auch kurzzeitige Unterbrechungen haben.

Es läuft mit Wlan, aber oft nicht stabil genug. Der Aufbau eines Lan zu weiter entfernten Einheiten ist aufwändig, lohnt aber immer.

Alle Daten werden über DbLog gespeichert und die Graphen daraus gewonnen.

Für den Fronius Wechselrichter ist das Technician Passwort erforderlich, um die Kommunikation z.B. über Modbus zu ermöglichen.

Anleitungen dazu stehen in den Handbüchern der Firma Fronius.

Auf dem System läuft die Software EVCC, die das Laden eines Fahrzeugs komfortabel steuern kann. (aber leider auch etwas kostet :))

Grundstruktur

Der Wechselrichter wird über das Modul fronius ausgelesen und div. Userreadings erzeugt.

Zusätzlich werden über HTTPMOD weitere Daten ausgelesen.

Der Speicher ist über den Wechselrichter per ModbusAttr erreichbar sowie auch direkt über das Modul BYDBox.

Daraus ergeben sich zusätzlich gebrauchbare Darstellungen des Batteriezustands.

Bezug, Einspeisung, Erzeugung und Hausverbrauch werden über vier ElectricityCalculator Module erzeugt,

diese Module erzeugen auch die gesammten Statistikdaten. (Heute, Gestern, Monat, Vormonat, Jahr)

Zwei weitere Dummys plus Berechnungsroutinen erhalten die Daten Eigenverbrauchsquote und Autarkiegrad.

Das sehr umfangreiche Modul SolarForecast wird integriert und viele Graphen dargestellt.

Eine größere readingsGroup stellt die Gesamtstatistik der Anlage dar.

Das optinonale Programm EVCC wird integriert und kann auch gesteuert werden.

Einige FTUI2 Beispiele runden die Darstellung auf einem Tablet ab.

In die Datei 99_myUtils.pm die Berechnungsroutinen eintragen:

sub get_eigenverbrauch 
{
  my($erzeugung,$einspeisung) = @_;
	return(100) if ($erzeugung)<=0;
my($eigenverbrauch)=(($erzeugung)-($einspeisung))/($erzeugung)*100;
    return($eigenverbrauch);
}

sub get_autarkie
{
  my($erzeugung,$einspeisung,$bezug) = @_;
  my($autarkie)=(($erzeugung)-($einspeisung))/(($erzeugung)-($einspeisung)+($bezug))*100;
  return($autarkie);
}

Zusätzliche Routinen in 99_myUtils.pm um zu kleine oder auch zu große Werte auszusondern. Das "verschönert" die Graphen; kann auch weggelassen werden. Hintergrund: Integralberechnungen übersteuern beim Start.

sub reduce_max_value
{
  my($device, $reading, $max_value)=@_;
  # Begrenzung der Ausgabewerte für Graphen
  my($Grenzwert) = ReadingsVal($device,$reading, 0);
   return($max_value) if (ReadingsVal($device, $reading,0) > $max_value );
  return($Grenzwert); 
}

sub reduce_min_value
{
  my($device, $reading, $min_value)=@_;
  # Begrenzung der Ausgabewerte für Graphen
  my($Grenzwert) = ReadingsVal($device,$reading, 0);
   return(0) if (ReadingsVal($device, $reading,0) <= $min_value );
  return($Grenzwert); 
}

Alle 15 Min erneute Berechnung der Werte (oder eine längere Zeit setzen...)
