I just bought a Bluetti power brick for my home, to store solar electricity - AC500 and B300, 5K inverter and 3K battery. I run a 7K BTU mobile AC unit in my computer room. hot air is pumped outside through the window. System works well. All houses in Australia are 240 V x 10 A. My shed a 3 phase plug - 240 V x 15 A.
