@Gabrielu

Your battery is charged. Loads are low.

If you switch off the kuche one does the other one ramp up to meet demand? If it (is able to because of orientation and there is not shading or other reason to not be producing) does, then there is no problem there.

What she's saying is that there's not enough load on the system to see if there's a problem. The batteries are full. If you turn off AC input and then the solar input to one MPPT, the other MPPT should increase output to compensate. If the garage MPPT covers the load with Küche off, there's no problem with your system. What you're seeing is the automation working.
