How to limit the max charge current to 28A

I’m want to limit the charge current to 28A of my LIFEPO4 battery. I’m using an Orion XS 50 which I can set to 28A and a smartsolar MPPT 100/30 which I also can limit. How can I limit the sum of those two to 28A charge current. The same question for a Multiplus 12-1200-50 and the Smartsolar? I’m using Venus OS on a Raspberry Pi and all devices are connected via ve.direct

Many thanks Matthias! It worked.


Now another question; Is it possible to use all solar power that's available en use only the missing power from the grid for the inverter?

This only works for DC loads!

Sounds like a flaw, or an opportunity for improvement, but thanks for pointing it out, didnt know that

Using power from the battery (or DC PV) to supply AC loads is ESS and requires NS protection and is not allowed in mobile systems (at last here in Germany).

Only thing you can do is to use the "ignore AC IN" feature to connect/disconnect the grid if needed.

I really need to study the ESS function, sorry
