IANAEE but would it be possible to use a DC compressor and rectify the mains, instead of using an AC compressor and inverting the PV?

- sitharus 9y agoYes, but 3-phase AC motors require less maintenance and are more efficient than brushed DC motors. Most traction applications are now using AC motors with inverters instead of DC.
- lostapathy 9y agoPowerwalls only output single phase AC, not 3-phase. Brushless DC motors actually have an awful lot in common with 3 phase motors, though, in terms of operating characteristics and performance.
- walrus01 9y agoYou theoretically could, but then you would have a special weird setup that doesn't match 99.9% of the similar installation base of air conditioners on the same island. Making repairs, maintenance and such very costly. You generally want to generate usable AC power from any significant sort of solar system, so that you can use it for more than just air conditioners.
