Is it allowed to connect a Fronius Primo 3.6-1 to one ACout1 from one of the 3 MP2?

Or is it just recommended to connect a 3 phase Fronius to a 3 Phase ESS?

As long as you are within the factor 1.0 rule it's totally fine.

Thanks for the reply.

I set up only the first MP2 and used the saved config for the other two as well.

If I connect the Fronius to ACout to e.g. L1 the ESS master, do I need to and can I use the updated config to update the slaves?

Or is it not needed?
