Another factor is if your appliances are gas or electric, if you have an electric range/stove/water heater/dryer that's going to be a good chunk. Best thing you can do is look at your power bill and see how much power you're using in a month and divide by 30 to get an idea of how long 18kwh will last you. For my 2500 sqft home in Florida, I typically use about 90-100kwh a day in summer, so this would only last a few hours.
As far as how to recharge it when there's no grid, your options are basically solar panels, a generator, or maybe a v2h electric vehicle
Generator: good for outages, but otherwise little utility and expensive to operate.
Solar + battery: expensive to implement but proven savings over their lifetime and good for power outages (though less flexible than generator)... Also cool your roof so some passive savings in cooling months.
I have a gen, still want solar with a gen input for extended outages.

My goal is to recoup costs through energy bill savings and for it to also serve as backup power during outages.
Also, what is the best way to recharge these during outages? I'm in Texas and when our grid fails we're out for 3/4 days at a time.
Thanks much in advance.
A. In my slightly larger Northeast home, three units could cover a summer day (outages usually <24 hrs), but at ~$32k it's not worth it.
B. For a fail-safe and capability of extended run setup, I can pair it with trifuel generator, but ~$35k—overkill for me.
C. A standby generator runs ~$10-15k, lasts 10–20 years, and while it's a single point of failure, the risk is low. I'd rather accept that risk and add a small portable battery for essentials like the sump pumps.
But I don't have good off-peak rates. Depends on your off-peak discount, the math may work. I would go with B if the math works.
I responded with what a gas line is.
You then wrote utility-provided natural gas lines only reach 50% of American households.
So what?
Long story short: It is not worth it.
I would think about installing some solar panels if I were you. Everybody got them nowdays in my home country.

I just dont know about these super expensive battery packs when leasing an EV with V2H is genuinely a better option with WAY more capacity. I feel like V2H is a much better solution if someone is serious about battery backups because automotive battery packs are larger than even a massive home backup system, one that would cost you $30k+.

I had a problem from the very beginning, and it took EcoFlow 5 MONTHS to get me replacements, and this was with priority. They (Costco and EcoFlow) use FedEx to deliver, at least in my area, and I think that probably contributed to the problems due to how rough things were handled, as evidenced by the condition of the boxes I got. I like the hardware, but their firmware updates had version dependency issues. Often times, the SHP2 or DPU would get a firmware update that would break communication to the other system, and you'd have to wait a few days for a fix or email them to roll back your system.
EcoFlow's support is also extremely slow. I wouldn't say terrible quality, since they did try to solve my issues. It's just that they require lots of pictures and videos, and tons of testing to figure things out. But with this system being a critical piece of infrastructure, I think their support is completely inadequate. If you can use a multimeter, then I think you can "win" at support, but be prepared to work in a live panel.
For the average person, I don't recommend the SHP2 + DPU combo. If you only need the DPU, then it might be ok.
