So over the course of a day, just my "idle" usage would drain this setup in less than 1 day. If you had this just connected to a fridge and freezer, you could probably go a week or longer (depending on efficiency rating of course).

Why would anybody spend this much money on batteries for whole home instead of just getting a natural gas generac generator or something with transfer? I could see maybe off grid with a large solar array. What other purpose could something this large serve

Also good for those who do have the skills but whose time is better spent doing other things, or who simply choose to spend it doing other things and can comfortably buy an EcoFlow instead. For example I love the idea of building one DIY, and could easily do it. But I'm leaning towards just buying one. Easier, faster, zero liability issues in case of failure, etc.
When I think of poor power infrastructure, I think it would be disingenuous (and downright unfair!) to leave good old Texas off of a list that also has California on it. They didn't let people die in a 100% preventable winter grid failure to be left off of this list now.

As others have alluded to, it depends entirely on your usage.
7,200Wh? If your toaster uses 1,000W --> you're looking at ~7.2 hours (assuming no losses, perfect conversion etc.).
Your fridge pulls 200W while running, and has a ~50% duty cycle? 7,200W/200W = 36 hours --> 50% duty cycle means is only runs 50% of the time --> 2x36h = 72 hours.
10x 10W LED bulbs --> 100W
200W fridge 50% duty cycle --> 100W
Router + ONT --> 20W
Laptop + phones + tablets --> 40W
----------------------------------------
260W --> 7,200/260 = ~27 hours.
This is just a fictional setup, based on estimates I've made. Best thing to do is get an idea of what you expect your load to be during a power outage. You can use that to calculate how long one of these might last.
Personally, I love the idea of one or two of these. Why? Generator runs during the day? Great. Noisy, subject to theft, etc. but during the day you can keep an eye on it. At night, these can be inside the house, 100% silent... Zero risk of theft. Run the fridge, internet, basic sh!t overnight. In the morning --> fire up the generator --> charge these battery/batteries while running everything else as well.
Don't forget to research the massive 30% tax credit available when you purchase one (or more) of these!! I believe minimum capacity needs to be 3kWh/3000Wh to qualify. Applies to renters as well, which is huge.

Oooooo... I've been resisting buy one or two of these until Black Friday. I'd like to combine a great price with the 30% tax credit. I wonder if they'll be announced or available before or by Black Friday 2023 🤔🤔🤔?
Thanks for sharing!!

Use google translate if you dont read german.
6kwh batteries, up to 5 per unit and can combine 3 units for a total of 90kwh.
Part of me says this is made for a whole other market then the delta pro, but since you can buy just 1 6kwh battery maybe not and they just made the system wildly expandable.
Grain of salt since its not an official release from Ecoflow.
