Subject setup is for "true free nights" electricity plan here in Houston TX. with two mini splits cooling the essential space and the essential loads load center connected to the inverter it works...
like $6 electricity bill per month. Not mentioning that 115V 2000W generator, or 3000W inverter connected to the EH/HEV 12V battery can provide really good backup in case of prolonged power outages. Live tested - load center wiring needs some planning for only L1N power from generator/inverter, but doable.
