Switching AC Charging of Luna for cascaded inverters

[mirisbowring]

Hi,

I would like to have the option to enable and disable the "ac charging" option of my luna system.
I've seen #575 already but this one is different since it wants to forcibly charge from grid.

In my case i have a cascade of inverters and would like to enable ac charging during day and disable ac charging if the other inverters don't have enough yield to enable the battery to power off if min soc is reached within night (keeping the battery in ac charging consumes too much energy in winter).

So I don't want to force ac charging to a specific soc. :)

Thanks !
