3 phase, battery based off grid solar system?

The title has been clarified with an added comma
3 phase, battery based

Three SMA Sunny Islands would work. Usually set up as one battery bank they all feed off. One unit is the master with two slaves.

So to make it clear to other readers, it is not the battery that is three phase as the title incorrectly suggests.

Schneider makes huge 3ph GT systems, so I expect their Off Grid systems would be as good. Battery size would be determined by mfg's min recommendation, and your loads & runtime. For your backup, you will need a 3ph generator,
You might consider conventional off grid, and just supplemental generator only when you need 3ph.

HI there,
What is the consensus for the top quality most reliable 3 phase battery based off grid solar system. I gather that most manufactures require 3 inverters. Would you also need three battery banks?
Any feed back is appreciated, or in point in the right direction hopefully.
