Extremely expensive, not flexible, stuck in an ecosystem, hard to scale, etc.
A Delta Pro/Ultra I would say is good up to a RV or something because the power demands are not as high and you can take advantage of its portable nature.
Since anything powering your home full time does not need to be portable, your much better off with a DIY system from Victron, EG4, etc.
DIY meaning piece by piece not so much that you have to do the work yourself, as even this system your paying an electrician to install the panel, so may as well pay them (less) to install a big inverter panel instead.
Here are some facts
12kWh "enough for a week" based on the advertisement that is enough for a few hours at my house. I use 60kWh a day on a normal day when I am home.
The average home probably at least 30kWh
The batteries are 6000Wh each costing over $2000 each with a maximum expansion point.
DIY you can buy a 5000Wh rack mount battery with more features and protections built in for under $1000 so if you scale up to say a 60,000Wh system just the battery alone
Delta Pro Ultra 60,000Wh = ~$22,000.00
DIY 60,000Wh = ~$10,800
That alone will pay for your install costs, stronger and better inverter, and even allow buying a backup system (or better solar)
Then features, the Ultra cant do things like EPS (Emergency Power Mode) for the 20ms UPS feature while also in self power mode to make use of solar power.
It also has a pretty terrible limitation for pass thru power.
This was my first big deal breaker and why I went with something else, as this is a very standard feature for a mid range hybrid inverter.
72000w also is not even strong enough to run most homes with HVAC. so you would need to buy two of these to get enough power, and that makes the cost start to go sky rocket (and you have to buy additional inverters to expand battery capacity as well)
I can keep going, the list is pretty long but I think you get the idea.
That said I own over 12 Ecoflow Power Stations and I pre-ordered the Bluetti Apex 300 so I am not biased or hating, just honest and transparent and I don't drink the Ecoflow Koolaid like most people on the respective FB/Reddit groups.
As a matter of fact, they hate me because I keep sharing ideas on how to hack their equipment to save money

The primary use for my setup is to serve me during a power outage at home AND to be as seamless as possible so that if I were not home, my wife/family wouldn't really need to do anything to continue living 'normally' --- at least for ~10-20 hours. I do have a tri-fuel generator that I run on NG which I wired to an outlet that sits between my main panel AND the SHP2 panel that both have lockout switches installed. This gives me flexibiilty to either power up the secondary circuits that I did not move over to the SHP2 and/or re-charge the EF DP batteries in the case of an extended outage. This is something that I would likely need to be home for IF it were needed as I don't think anybody else in my house could figure it out.
I have added 4x 400w solar panels on a ground mount as a 'fun project' which do an 'ok' job of recharging the DP batteries on a daily basis. The SHP2 will then use the excess power collected in the batteries to power ALL fo the circuits on that panel until the overall battery % is depleted to 50% (this is configurable, but I don't ever want to have <50% charge in case there is an outage). This saves me a few bucks every month off of my electric bill --- while not my primary goal, it is enjoyable to track this throgh the 'very solid' EF app. I should note that the switch from grid to battery power using this mode is seamless -- nobody would ever know when the SHP2 transitions from one power source to another unless you brought up the app.
Additionally, there is a feature called 'storm tracker' which will automatically charge up all batteries to 100% (using grid power) within 24 hours of a storm approaching my area. This has happened on several occassions and would maximize my battery storage should power be knocked out during a storm.
I cannot speak to how seamless some of this functionality would operate in a DIY system, but for my specific needs it works really well. Did I spend more $$ (possibly a lot more??) for my EF setup that I would have using a DIY, almost certainly "yes", but the system is very slick in the way it is setup/connects/etc -- I would have had to invest more time learning how to best setup and organize a DIY system (i.e. buy a rack -- maybe several, buy a bunch of low AWG wires to interconnect things, etc.).
In short, I am quite pleased with the overall functionality that I am getting out of the system and the overall ease of setup and use. I'd advise anybody considering this or a DIY setup to do a bunch of research before deciding what is best for your needs.
EDITED NOTE: I actually purchased this particualr deal from Costco at this price the last time it was offered, but was able to snag 2x additional batterest at $1500 ea. from the Home Depot deal ~1.5 months ago. If there is another sale on batteries at a similar price point in the future, I'll consider further expansion of my system. The reason I mention this is that there are ways to save some $$$ once you enter the EF ecosystem that 'should' save you more $$$ over the typical prices -- obvioulsy, you need a little patience and to NOT have an urgent need for this to play out.

Wow, do you have a subreddit or website, or way I can ask you some questions?
1) In short term, I'm looking for a system than could be a whole-house UPS to avoid short brown-outs, because we have a lot of construction in our area AND lightning. besides needing to reset every clock, I believe these short outages are hard on our HVAC, appliances, EVSE.
Longer term, I'm curious about other options:
2) A large portable battery (like this Delta) capable of partial-charging an EV (yes I understand how impractical) with connections for a portable solar panel, potentially 400w or more.
3) While currently in a large but energy efficient house, there's a chance i move to an RV+EV. I would like be able to at least supplement some of our power from solar, though of course not all.
Interested in a smart energy system to track my usage, and wondering if I should only pursue DIY Portable battery & solutions, since likelihood of selling house and moving to Motorhome.
Sorry for the long, somewhat off-topic questions, you just seem to understand this topic better than anyone else I can find.

You have a few options but I think you are a good candidate for a DIY Solar Cart
For about the price of a Delta unit you can get something that can power an entire house or charge an EV.
The issue is you want backup power, a portable cart is usually used on a manual transfer switch for backup power.
To have the inverter offer backup power means getting it installed and attached to the power grid.
You could still actually make that work with something like Anderson connectors to make it hit pluggable.
Maybe check this out see if it gives you some direction: https://youtu.be/72mPUBpFrhQ?si=
Yes the EV credit is getting axed in 90 days, which is unfortunate.
