Here is a study of an inverter, looking at power transistor options:

I saw first, which is 1000V 50A - safe for a 20kW system, looks like we need 4 of them? IGBT obsolete, need 4 of them at $13 each. [1]

Here is the thesis - P. 55 shows weight and power.

Is the bottom line 20kW for $50, or $2.5/kw of switching power?
