3x us3000c - is one power cable enough?

I have 3x pylontech us3000c connected. Connection is done by one original pylontech cable. Question is if it's enough? Or how to connect next one cable? Thanks

What is is it running?

You can daisy chain the batteries (short cables come with each battery) and the cable is rated for 100A so is just a little short of a 5kva if running hard.

No need, as long as your loads are within the cable rating.

BMS set a charge/discharge limit to 111A. I have a multiplus II 5kW so I think discharge isn't a problém, but for charge I have a mppt 450/100 and 250/60 so charge can exceed 100A

You will find the batteries will limit the charge current within the system.

You can, in DVCC, set the max charge current to be a max of 100A to be sure.
