This is my installation, to which I want to add an ET112 meter, as shown in the diagram. I have air conditioners connected to load 1 (high consumption). I would like to know if by adding this meter, I can configure (via node-red) that when the total consumption exceeds a certain amount (for example, 1000W), the Multiplus injects the excess photovoltaic energy into the grid so that it powers the air conditioners. Is this configuration viable? Will it work?

That way the ET112 doesn’t “see” the loads 1.
The grid needs to be connected to the grid and the AC IN + Loads 14 need to be connected both to the output of the ET112.

So if I connect it like this, it should work?

Yes!

… and if you configure it as ESS.
