I had to search it up. Rather interesting a whole house main panel replacement (smart panel -span?) designed to work with power walls batteries and the grid tie hybrid setups thus providing all kinds of automation. Bit pricey at the $3500 list for the likes of me but definitely a consideration for them folks in Cali that get that an hour working at Mickey D'sIsn't this basically what the span smart load center purports to do?
