Looking for input before I get silly.
Looking to go solar for the house for off grid living. Just wanna start small and scale up. So my highest month was 1407kwh and the lowest was 258kwh the average would be about 300~400kwh the 1407kwh month was because I was doing a lot of welding out of my garage. So I’m thinking move the house to off grid and the garage to local power until I can upscale. So what should the best course of action for batteries and inverter?
Thanks for the help
