What is the ideal DVCC for a 400AH of pylontech batteries?

I have 4 units of US 5000 from pylontech with 400AH and 19.200 W in total.

I have a 10 Panels of 450 W each in in 2 parallel lines of 5 units each line with 4500 W and 250 V and around 90 Amps in total.

In DVCC i have a 52,2 V limit voltage wich i think is the correct (you can correct here also, but it works fine)

But i don´t know about what is the ideal maximum charging current.

No limit A?

Or 90A?

Or a smaller amount?

Check the manual. From memory recommended max continuous is 80A per battery, so 320A. But the supplied cables are only good for 100A, so need to go to busbars if you're drawing a lot of power or charging very hard.

Pylon's are managed batteries, they will set their own parameters.

The voltage limit in DVCC is not meant for permanent use, it is only to assist with initial balancing issues, if there are any.

The settings required in DVCC will be forced on automatically.

This being said i hope you are also actually programming the victron components as individuals as well.
