Off-topic CAN or RS485 for Inverter - BMS

[xXBrunoXx]

Hi, Can someone explain what difference is between CAN and RS485 connection from power inverter to lithium battery BMS. And if it matters what I use .
Both of my inverter and 5kWh battery has CAN and RS485 ports, and I'm not sure what to use. The manuals explain only how to config , settings..
Inverter is Growatt spf5000es , battery is Ampleness ( chinese brand ).
They sell also as bundle, and are compatible.
Thank you.

One RS485 is used if more than one battery is used, 2 in parallel for example. And the other RS485, and CAN are for connecting to the inverter, so I can use either of them.
