Best practices for stack of two or more NOAH 2000

[mabiste]

What is better when I have more than one NOAH 2000?

Stack them and only connect the top NOAH (the master) to the NOAH MQTT-Broker? Or is it better to not stack them (I know, then I have to connect each of them to my inverter and have to consider the power limits of the inverter) and connect each of them to the NOAH MQTT-Broker?

Why I asking this:
Last week, I've implemented my 'GroBro infrastructure' and it works perfectly 😊 (great thanks to to Robert and all contributors!).
Since yesterday, my second (buttom) NOAH is not recognized / published by the master NOAH when waking up from sleeping at night. I can only see one NOAH at Home Assistant and ShinePhone App, even the second NOAH seems to be working.
I'm clear of that this is no GeoBro issue, but the question is if it is a good idea to not stack the NOAHs and connect each to the local broaker?

Many thanks!

stacking noah is not the best deal
only the top noah will show up providing informations concerning the top (not SOC% ) , the second and third are just dumb

best way if you got a 1600 inverter is to splitt the 2 noahs
works here with multiple noahs and inverters like a charm

Which Inverters are you using?

4 Noahs in 2 x 2 Stacks on a HMS1600
Works Pretty Well noah output of each Stack 800 so 2 x 800 no Problem for the hms1600
