So I'm looking at the growatt 5k 48v inverter. I know electrical pretty well and we run on 240 volts split phase 60hz. Air compressors, hvac units and well pumps use 240v split phase. This inverter shows to be 240v single phase. Let's forget anything 120 volts because I understand the need for the autotransformer in this area. Signature solar says this 240v single phase inverter will run a hvac unit designed for split phase 240v. I don't see for the life of me how single phase 240v will run anything designed for split phase. Yes I know that a hvac unit doesn't have a neutral wire. All hvac units require 2 120v legs with a ground. Also if they inverter is 240 single phase what input voltage can I put into? Can I put 240v split phase into this inverter or only 120v since we run on 240v split phase and this inverter is single phase 240v?
