3t10K-HVES-G5 Verkabelung | SmartgridOne Documentation

Diese Seite beschreibt die Kommunikation mit einem Solis 3T10K über Modbus-RTU (rs485). Standardmäßig ist der Wechselrichter auf Adresse 1 eingestellt. Dies kann über das Display des Wechselrichters geändert werden. Das Vorgehen finden Sie in Kapitel 7.3.2 der Bedienungsanleitung. Die RS485-Klemmen befinden sich am unteren Teil des Wechselrichters hinter einer Schutzabdeckung.

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.
