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.
