Carlo Gavazzi with MultiplusII

Hi All,


Love my system..


A question. I still need to connect my Carlo Gavazzi ET112 to my system. Is the only way to do this through the Mk3 to the VenusGX? No way to connect it directly to the VE.Bus?


MultiplusII, VenusGX, 150/100 MPPT, 2xPylontechUS3000


Thanks

Hello

No, you cannot connect Carlo Gavazzi through VE.Bus or MK3. Carlo Gavazzi is RS-485 MODBUS, a completely different protocol to VE.Bus.

You need to connect Carlo Gavazzi with a RS-485 to USB interface cable directly to the VenusGX. Also there is Zigbee for a wireless connection if you want to.

Thanks. It would thus be a normal USB cable with 3 of the 4 wires connected? Or is there some processing happening in the usb plug?

If you want to guarantee functionality and support, please use the Victron 485 interface.
