150kW @12V is 12,500 AMPs plus efficiency losses.
Nice try
You would start with a 450Vdc PV array then use synchronous tri-phase bipolar bridge switching with a pseudo-sine wave.
A solution for 1% of this power in single phase split 240Vac voltages looks like this.

The magnetics are small due to the storage energy required is only a cycle at high frequency , rather than a cycle at 50 Hz. But the switching is shared by sequential devices to simulate a better sine wave.
The schematic is simplified and does not show gate pulse generation.
At some point the cost of electronic inverters needs step down transformers to transfer MW power levels so inversion is done at higher voltage where IGBT's work well. See Mitsubishi for examples

agreed,
you shouldn't be doing this ... the company should be employing an experienced EE
