Here's some basic info on BLDC motors..

I think the name "Inverter" (converting DC to AC) is a bit confusing,
since the DC really isn't so much converted into AC, but into DC pluses.
Sorta like PWM pulses where Pulse-Width and the frequency of those pluses,
set the RPMs of the motor.

Grid--->230VAC--->DC--->(Transistor switches) making DC pulses to feed the Brushless DC motor..

There are mini-split designs that use only DC, (from PV etc) no AC is needed.
