Three Phase HV Hybrid Inverters (SG0XHP3-EU)	SUN-5/6/8/10/12/15/20/25/29.9/30/35/40/50/60/70/75/80K
Single Phase String Inverters (G0XP1-EU)	SUN-1/1.5/2/2.2/2.5/2.7/3/3.3/3.6/4/4.2/4.6/5/5.2/6/6.2/7/7.5/8/9/10/10.5K
Three Phase String Inverters (G0XP3-EU)	SUN-3/4/5/6/7/8/9/10/12/15/18/20/22/23/25/30/35/36/40/45/50/60/70/75/80/90/100/120/125/130/135/136K

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 1 / Modbus-485_B	RS485 A	RS485_POS	RS485 A	TX+
Pin 2 / Modbus-485_A	RS485 B	RS485_NEG	RS485 B	TX-
Pin 3 / GND_485	RS GND	GND	Not available	G

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.

Vai a “Schermata principale” >> “Impostazioni di sistema” >> “Funzione avanzata.”

Modbus SN deve essere impostato su un numero compreso tra 1 e 247. Non selezionare 0!! Nota che, se sono presenti più dispositivi sul bus RS485, a ciascuno deve essere assegnato un numero univoco. Questo è l'indirizzo.
Seleziona Slave.
“EX_meter For CT” deve essere selezionato solo quando un contatore aggiuntivo è collegato direttamente all'inverter. Se è presente solo un contatore in parallelo con il SmartgridOne Controller, deve essere deselezionato.
Assicurati che le seguenti impostazioni siano tutte corrette: "Max A Charge", "Max A Discharge", "Grid Charge Ampere"
