There is almost always better technology available than the technology that we actually buy and use. COST is usually the limiting factor, not technological capability.
But that is my point ! Many (most?) of the top quality inverters on the market are using technology that is >10 years old. There is no need for huge transformers and modern Power MOSFETs limit the losses due to heating. These things REDUCE cost and improve efficiency.

5000W 12V input inverters - not impossible - not even hard. That's 427 amps at 12V.
IMHO anyone wanting to run a 5000W inverter off of 12VDC is nuts ! Somewhere around 2000W, you should be using 24VDC. Above 4000W, 48VDC.
