Wiring diagram for multiple Pylontech US3000C battery banks

Heya,

Can someone please help me with a wiring diagram for 4 banks and each bank having 4 batteries in it with a total of 16 x US3000C Pylontech batteries, all of this will be done without a LV-Hub (I know is possible because is said so in the docs).
My problem is how do I connect all 4 banks to each other using the positive and negative cables ? Do I use an isolated bus bar and then the first and last battery for each bank will be connected using a Victron Lynx Power In to the inverter or how do I do it?

Thank you!

I’ve the same setup running.

Every 4 pylontechs are in parallel.

Every stack of 4 is connected with a 100A fuse to a lynx distributor.

The oem cables are rated for up to 125A. On top a total of 400A is enough for my setup.

Just use a lynx distributor.

Fusing is then also done there.

In total 4 cables from the lynx to the 4 x4 pylonstacks. Don’t interconnect them extra.

@KLandos thanks a bunch! I thought I need to connect them dirrectly too. The fuses should be MEGA-fuse 300A/58V or MEGA-fuse 100A/32V is enough?

in total 4 cables from the lynx to the 4 x4 pylonstacks.

4 positive and 4 negatives ?
