setting two mppt in CCGX ve direct

Hello everyone, I will tell you my case. I have a ccgx to which I have connected a mppt 150/70 by ve direct cable. Now I want to add a mppt 150/35 on the other available ve direct input. I have configured the two mppt with exactly the same parameters, is it the right thing to do?

I have seen something about DVCC and this has confused me, I don't know if I have to alter some configuration in the CCGX.


Thanks for your help

Yes this is correct.

DVCC is used for controlling the charge to lithium batteries as the charge approaches full (>09%) This allows the ballancing to take place properly, without getting an over voltage indication on any cell.

DVCC also controls charge current, useful for AGM as well.

You will find it in the menu, under settings
