Is there a power limit between Loads and Critical Loads for Multiplus II?

Hello Community, I could not find any information regarding the following question: If running a PV inverter on critical loads output of a MultiPlus II to supply regular loads during grid failure, is there a power limit to regard? Would a 5kVA MultiPlus II unit be sufficient to connect a 10kVP PV system on Critical Loads output? Thank you!

Hi

No, 1 to 1 rule applies here.

Thank you Rob, I reckon the "no" answers my first question. Take care!

Hi

That,s OK, yes use AC coupling to use a over sized PV system etc.

Just to clarify it if anyone will read this question in the future:

Using a PV inverter on the protected output of a Multiplus will require a 1:1 sizing of both units. A more cost efficient alternative could be an AC/DC coupling like shown here:
