This is a new product from Schneider to solve a few of the issues. A
recent webinar had the 3 phase issue brought up and this 200A pre wired
panel. The 3 phase webinar is next, I heard.....
https://solar.se.com/us/en/?s=865-BCS-2200
Whole home backup or subpanel backup with up to 200
A rating
* Service entrance rated when installed with a main breaker
* Top or bottom entry for grid input
* Optional non-backup circuit, making it easy to backup an
existing panel and remove select non-critical loads
* Fast 50 ms transfer from grid connected to backup power
operation
* Reliable backup power and load starting performance
with the compatible XW Pro inverters
* Connect up to 4 XW Pro inverters for up to 27 kW
continuous and 48 kW peak backup power capability

I've worked with a few larger 3-phase Conext XW systems - 3 inverters
and 6 inverters.
The inverters' output capabilities are slightly reduced since they have
to be converted to 120 V, effectively doubling the output current.
Also,they required an external transfer switch. Even with 3 inverters
configured for 3-phase, I would recommend an external transfer. The
relays have a habit of welding.
Once they were configured properly, there was no problem starting large
HVAC loads and even large single phase loads were OK.

That's a market segment that no inverter company that I know of really
makes a product for.
I would probably use 3 Sol-Ark 12K inverters.
You'll have to be careful with load balancing with any Sol-Ark inverter
though.
Schneider would also work but you will have a lot of individual
components and you would need to be careful that the internal transfer
switch is within its 60 amp capacity limit from a generator or other
source. With multiple Schneider inverters there is the possibility that
not all of the internal transfer switches will trip at exactly the
same time causing the transfer switch in one inverter to take the whole
load.
I was originally a staunch Outback fan but we've stopped using their
products after we had repeated Incidents of equipment not working right
out of the box.

Outback FX R can be built to be 3 phase and solark also works, for 30 k
l would look at solark, 3 12's or 15's.

Hello Wrenches,
What inverter options are there for 3 phase, UL listed, off-grid
inverter systems in the 30kW+ category?
It's been quite a while since I dove into this...
Thanks!
