This is the kind of setup I would like to have. I would use it to run my heat pump / air conditioner and maybe a few other things like the microwave oven. And it would be used for charging my EV when it’s at home.
The two solar PV panels are 800 watts total. The controller is good for up to 3000 watts.
The batteries are good for >3000 cycles so that would be for ten years or more.
