3 ways to connect, 3 Growatt inverters. 3P/1P/1P Which to choose?

[solarrig]

hello, need recommendation for Growat setup.

I have 3 phase grid in my home. But don’t have and don’t use any of 3P devices. As I don’t have plans to have or use. I bought 3 PCS of Growatt spf5000es inverters. I have 3 different roof’s (east, south, west) so i need 3 mppt’s. Each of the Growatts will have it’s own string and 1 shared battery, that they will charge and use.

Now the question on how to connect them? It looks like there are 3 ways to do it.

A. Connect them together and use in 3P mode. (but don’t have a need for that).
B. Connect them together and use in 1P mode. (What’s the point? Load balancing?)
C. Do not connect them together at all and use independently?

To make it more clear, i’ve made this diagram.
Would be very nice to hear your opinions.

Thank you.

Rather than looking at all 3 can you just connect to one phase, set it all up, & try that?
The rest might be self explanatory.

Do you need any 240 volt for anything in your home

Belay the previous I see the 5000es is 230 euro voltage

if no 3 phase is required parallel all three and run how ever many needed for load one could be left off as a ready service spare if one goes down

Sounds good.
