I browsed the thread above, you mentioned 64 CATl cells (4 x 16S, I assume) didn't see where you may have mentioned the Ah size of your batteries. Typically the charge rate for LFP cells is 1C and below. Ideally charging at 0.5C and below is best for longer life. I understand that when running a generator you would wish to charge as fast as possible and shut off that noisy machine. For example, if your CATL cells are 100Ah then I would set the chargers at 50Amps each and no more. That cuts your charging demand down to 10KW.
As far as the house, typically the continuous load for a breaker should be no more than 80%. So you should limit your house demand to 19.2KW. That said, Is your house all electric? Do you have propane or Nat Gas? At this point we are just guessing. I highly recommend actually testing the PEAK and AVERAGE current draw on your house with something like an Emporia Energy monitor that will keep track of usage and will produce a graph. The entry level device with 2 x 200A CT's is only $69.99. I'm using one of their 8 CT systems.
Lastly, one of the trade offs with MPP Solar and other value priced Inverters is the lack of some advanced features like Gen Support. Rather than spend a bunch of money on a massive generator, it would be better to consider managing the system and maybe consider some load control rather than the perhaps unrealistic goal of 100% "Plug and Play" operation.
