Do I really need the Max Pack?

Me too. 135 kWh would run my house for the day.
My usage is pretty consistent, benefits living near the cost in SoCal, rarely need AC, never need heat. I've replaced most of my lights with LEDs. Helps that it is not a large house at 1900sq ft.

I am adding solar in preparation for the Rivian. The Tesla has free super charging so I rarely charge that at home.

Out of the 135 or so I use per day the lions share goes to heating in the winter and A/C in the summer.You are lucky and you know that. Only 5.3 go to the Tesla. I too have free charging but certainly charging at home is much more convenient, phantom drain gets covered as it occurs, the Tesla warnings against using SCs unless it is necessary scare me and finally that the electricity is (at least at this time of the year) free means the only time I ever Supercharge is on road trips.

My wife and I built a new house a couple of years ago and finally built what I wanted, super energy efficient, super-strong as we're in hurricane country. I took some of the learnings from German's Passivhaus, Net Zero, etc. Over most of last year, I worked with my small town's alderman to change an ordinance on solar (it was super unfavorable to putting solar on your home) and then this spring added panels so we should now be "Net Zero" as far as electricity which is our major energy supply. All this being said, I would estimate, I have one of the top 5% most efficient homes in the USA and we still use somewhere between 30-50 kW/day.

Wow, that is awesome! We built a 2,700 sq. ft but since we are in Hurricane country, we built our house "encapsulated" thus we heat/cool the entire envelope, including the attic space. This puts us on par with a 4,000 sq. ft. house. I put 9.4 kW's of panels on, so on an annual basis, we should be a Net-zero. We're only 3 billing cycles into solar, but so far it's great.

Yes, when the sun shines it's fantastic. In the summer we produce about 25% more than we use. In the winter I'm estimating we will be short 70% of what we use. Not so great.

Same in Wisconsin, makes the ROI rough....

The solution is to put up more panels in places that are less than ideal so the sytem effectively "tracks" the sun. This solves the problem to some extent but destroys the ROI.

I’ve got gas heat and hot water, and don’t really use my AC much. I’ve averaged 230kW per month over the past year. That’s about 7.5kW per day. 😊
