Multiplus2 in parallel, so can I use AC2 for different things?

Dear All

I have two Mulitplus2 in parallel (5000VA x 2) that is supplying 230V to my DB.

Only using AC1out but AC2out is empty on both.


My question :

  1. Is it possible to connect different loads on the AC2out for each machine or must the loads be equal all the time (i.e. I have to parallel connect the AC2 to the same load). (I guess the one machine will then see a higher load all the time compared to the other?)


The idea behind this is to operate the boiler (CV) when SOC is above a set point and turn on the circulation pump with the other MP2 when temp is below XYZ (Using AC2 as a relay function).


If you have done something similar (switching on and off loads, depending on time, weather, etc), what did you use to achieve this (i.e. Node-red with relay contactor, Using GXcerbo to trigger, etc.) Please over explain with lots of pictures :) or a link to a discussion/solution will be greatly appreciated.

@Groningen

In parallel system AC-in and AC-out must be connected.

The same applies to AC-out2 if used.
