I see a post re "Benefits of Three Phase AC Pumps for Solar Water Pumping". In that post, a VFD (variable frequency drive) unit is used to generate three phase 230V AC from a single phase supply. The single phase supply being from a single inverter. Just thinking out loud here, but I have a couple of three phase air-con units. Anyone used a 1 Ph to 3Ph VFD to drive a 3Ph aircon unit? Maybe already covered, and my apologies if there is already a thread on this. I'm not sure how practical it would be as mostly I use the air-con at night and for sure the reason they are 3Ph is because they are fairly high wattage... just enquiring at this stage... Thanks!!
