SA definitely supports their batteries via RS-485, but there isn't any information on whether this will work using the communication hub. This system has 24 batteries with two networked groups of 12 batteries (16 is the max each group). Each group plugs into the hub for unified reporting. There are additional ports available on the hub, so I'm guessing I can get this to work, but which port and what type of cable is the real question. This battery system is not connected in a closed loop with the inverters, so I have the inverter CAN1 port available as well as the BAT CAN2 and the INV RS485-3 port. I'm thinking that last one is my best bet, but I don't know what pinout the USB to RS485 would use.
