Quelltext der Seite FOX ESS Photovoltaik-Anlage

=Allgemeines=
Meine Photovoltaik-Anlage besteht aus den Komponenten:
* FOX ESS H3-Pro Wechselrichter
* Fox EK11 Akku
* Fox A011KS1-E-2 Wallbox

[https://de.fox-ess.com/download/ Downloadbereich Fox]
[https://de.fox-ess.com/downloadses/ Downloadbereich Fox (veraltet?)]

Durch die Registerliste (MODBUS RTU) ist diese Seite doch auch wieder recht lang geworden. Die XML-Datei (Konvertierung) und die Programme werde ich auf eine eigene Seite auslagern.

=H3-Pro Wechselrichter=
[[Datei:FOXESS H3-Pro Schnittstellen.png|600px]]

Bisher hierhin ist mit Grid, EPS, Akku, DC alles klar nur bei den Com-Schnittstellen wird es etwas verworren.

Der Stecker J WiFi/GPRS/LAN (optional) ist ein USB-Port der wohl nur diese speziellen Module bedienen kann.

Bei den Steckern P und Q geht es aber irgendwie munter durcheinander.

[[Datei:FOXESS H3-PRO PQ.png|400px]]

P wird als COM1-12PIN und Q als COM2-24PIN in der (Stuecklisten-)Tabelle angegeben.

Diese Bezeichungen finden sich schwer oder gar nicht im Manual wieder.

Hier mal ein paar Nahaufnahmen Stecker P.

Der Stecker P hat auf der einen Seite 8 PCB Kontakte und auf der anderen Seite 4 PCB Kontake.

In Wechselrichtern wie dem Fox ESS H3 Pro sind TVS-Dioden typischerweise in den folgenden Bereichen integriert:
*DC-Eingänge: Schutz der Photovoltaik-Eingänge vor Überspannungen.
*Kommunikationsschnittstellen: Absicherung von RS485-, CAN- oder USB-Ports gegen elektrostatische Entladungen.
*AC-Ausgänge: Schutz der Netzanschlüsse vor transienten Überspannungen aus dem Stromnetz.

Und hier ein paar Nahaufnahmen Stecker Q.

==Register Liste==
Was schon mal gleich nervt ist die Verfuegbarkeit des Modbus Protocol und Register Dokuments der FOXESS H3 Pro Baureihe.

[[Datei:FOXESS Inverter Modbus Definition Deckblatt.png|mini]]

Bei FOX bin ich auf der Homepage nicht fuendig geworden, nur Scribd bietet es an.

Ab hier ein Transcript.

Die Tabellen dienen mir auch als Grundlage zum erstellen der XML/JSON-Dateien, die ich als Config fuer meine Programme [eigene Seite folgt] benutze.

 Marked * are only supported by some models or standard codes.

===DRM===

DRM Demand Response Mode

 DRM0 steht für "Demand Response Mode 0" und ist Teil eines Systems, das es Netzbetreibern ermöglicht, die Einspeiseleistung von Photovoltaikanlagen zu steuern. Dies geschieht oft über einen Funk-Rundsteuerempfänger (FRE), der Signale an den Wechselrichter sendet, um die Einspeiseleistung zu reduzieren oder ganz zu unterbrechen.

 Der Fox ESS H3 Pro Wechselrichter verfügt über einen DRM-Anschluss, an dem externe Steuerungssignale anliegen können. Insbesondere ist Pin 17 für das DRM0-Signal vorgesehen. Wenn ein externer FRE ein Signal sendet, das den Kontakt zwischen DRM0 (Pin 17) und einem der anderen DRM-Pins (z. B. DRM1, DRM2, DRM3) herstellt, erkennt der Wechselrichter dies und passt seine Einspeiseleistung entsprechend an.

Die verschiedenen DRM-Pins (siehe Kommunikation) entsprechen dabei unterschiedlichen Leistungsstufen:

    DRM1: 100 % Einspeiseleistung
    DRM2: 60 % Einspeiseleistung
    DRM3: 30 % Einspeiseleistung
    DRM4: 0 % Einspeiseleistung
    
Wenn beispielsweise DRM0 mit DRM2 verbunden wird, reduziert der Wechselrichter seine Einspeiseleistung auf 60 %.

Was bedeutet DRM0state?

Der Begriff DRM0state bezeichnet den aktuellen Status des DRM0-Eingangs. Er gibt an, ob und welche Verbindung zwischen DRM0 und den anderen DRM-Pins besteht, und somit, welche Einspeiseleistung der Wechselrichter aktuell ausführt.

=Kommunikation=

==Stromzaehler==
Im Lieferumfang des FOX ESS Wechselrichters ist ein Stromzaehler der Marke Chint DTSU666 (nicht wie im Manual steht DDSU 666).

DDSU666 = für 1 Phase
DTSU666 = für 3 Phasen

Technisch sind sie sich aehnlich (z. B. beide haben Modbus RS485), aber sie unterscheiden sich in der Anzahl der Phasen, die sie messen können.

====Tools====
Eine recht gute Erlaeuterung findet sich [https://www.fernhillsoftware.com/help/drivers/modbus/modbus-protocol.html hier], vor allem wegen der Beispiel-Frames. Wenn man erst mal den Aufbau der
Frames verstanden hat ist das Abfragen der Register ein Kinderspiel.

Von diesen Tools gibt es unzaehlige. Ich probiere einfach mal durch.

=====MODBUSTOOL=====
[https://github.com/ClassicDIY/ModbusTool]
[[Datei:Notebook RS485Adapter.jpg|mini]]
Das Programm laesst sich leicht in Betrieb nehmen (msi Download) macht auch das was es soll hat aber noch ein paar kleine Bugs/Schoenheitsfehler.
*Die Reiter des Registerfensters machen irgendwie was wollen.
*Die Connect paar mit dem Adapter (siehe Foto) problemlos moeglich.
*Der Vollstaendigkeit wegen hatte ich auf die Functions-Buttons noch die Function-Codes draufgeschrieben.
*Die Zahl hinter dem Poll, soll wohl die Anzahl der Wiederholungen angeben.
*Die Startadresse sollte auch in HEX moeglich sein.
*Unglueckliches Fensterformat. Mein ServiceNotebook (Panasonic Toughbook CF-52) hat nur eine Aufloesung von 1280x800, dadurch ist der Communication Log ohne scrollen nicht sichtbar.

[[Datei:MODBUSTOOL Master 1.png|400px]]

Beispielhaft sieht man jetzt hier das Ergebnis (3,3,1) die Abfrage (Read holding register) der Adressen 44, 46 und 47. Das sind die eingestelten Kommunikationparameter (siehe Tabelle oben).
