Paralleling 2 12kw inverters
Good afternoon everyone.
Could anyone please help with paralleling 2 x 12KW inverters with 3 x Pylontech US5000 batteries. Would it be possible to take a leg from the positive battery connection on the master inverter and connect it to the positive on the slave inverter? Then do the same from the negative from the master battery to the slave?

That's an old wives tale that only applies to wiring between inverter and battery in the first place and only with multiple batteries.
However, in reality, normal variations in internal resistance of batteries equal to about 6m of 25mm2 cable, which negates any cable length matching, and if you really wanted to match the batteries, you would need to test internal resistance of each battery and then add cable as required.
And it makes absolutely no difference for inverters to have the same voltage.
