Autarco LD-Serie RS485 Verkabelung | SmartgridOne Documentation

Diese Seite beschreibt die Kommunikation mit einem Autarco LD-Serie Hybridwechselrichter über Modbus-RTU (rs485).
Standardmäßig ist der Wechselrichter auf Adresse 1 eingestellt. Die RS485-Schnittstelle ist ein 4-poliger Anschluss an der Unterseite des Wechselrichters
hinter einer Schutzabdeckung. Die genaue Position ist im orangenen Kasten im Bild unten markiert:

Bei genauerem Hinsehen sieht der Anschluss so aus:

Für diesen 4-poligen Anschluss am Autarco Wechselrichter sollte ein passender Stecker verwendet werden, um eine Verbindung zum SmartgridOne Controller herzustellen.
Am SmartgridOne Controller kann der Wechselrichter an den RS485-Anschluss angeschlossen werden. Die Verdrahtung erfolgt wie folgt:

RS485 Wiring

For correct RS485 wiring: Follow the guidelines for RS485 wiring.
If the wiring shown in the table below is incorrect, please let us know.
There is no general consensus in the industry about the usage of A and B for the RS485 polarity, so it may be counterintuitive and opposite of what you might expect for some devices.

Device	SmartgridOne Controller model OM1	SmartgridOne Controller model IG8	RS485-USB converter	RS485-Ethernet converter
Pin 3	RS485 A	RS485_POS	RS485 A	TX+
Pin 4	RS485 B	RS485_NEG	RS485 B	TX-
N/A	RS GND	GND	Not available	G

NOTE: RS485 Device Addresses

You MUST give each device on the RS485 bus a unique address. Check the manual of the device on how to do this.
Use lower addresses first (1, 2, ...) because the SmartgridOne Controller will find them faster!
For each device, it is generally recommended to stick with the factory default baud rate, parity, and stop bits. The SmartgridOne Controller will scan on those first.
