I'm not sure I'd be confident that tax credit will exist next year
Could someone please explain for those of us that don't understand the electricity units.
This whole system, when fully charged, what can it power and how long, and what's the beefiest appliance they can power? I don't think anyone plans to run 220V electric dryer or huge whole house AC units, but can these provide enough power to 5-10 LED lightbulbs, home oil or gas furnace, maybe a TV and toaster, etc,
How do we illustrate how much power these can store?

I assume we need an electrician to hook these up to a switch so if power goes out we can use this?

Can anyone also tell me if it's a wild idea to completely run off these in like a remote cabin or in case of blackout? Or these don't charge that fast as quickly as they drain?

Sorry if this is the stupidest post you've ever seen, but I've been trying to figure out this for a while and it's been difficult.

We also have solar panels on our roof, but I always wondered why we can't just store the generated electricity and run off that instead of depending on grid and the generated electricity simply sold back to grid, and when power goes out, we can't use generated electricity unless we get huge batteries.

---

EDIT:
So I found this:

1 kWh can power:
Running a dishwasher (1,000 watts): 1 hour
Watching a 50″ LED TV (50 watts): 20 hours
Cooking in the oven (2000 Watts): 30 minutes
Running the refrigerator (300 Watts): 3 hours
Using a Playstation 4 (150 Watts): 6.66 hours



This deal is for 4kWh right? Does this mean, it's enough capacity to run a fridge for 12 hours with nothing else drawing power? (each) so it comes with 3 of these, total 12kWh right?
This means this battery can power fridge for 48 hours straight?

What's the charge speed compared to drain speed, like on a sunny day, for example, while it's charging at full potential, what is the generation power that you can drain it at the same speed and it would be almost 1:1 or less?
I am not a tax professional:

Yes, the EcoFlow DELTA Pro 3 qualifies for the 30% federal tax credit under the Residential Clean Energy Credit, provided it meets certain criteria. To be eligible, the battery storage system must have a capacity of at least 3 kilowatt-hours (kWh) and must be installed in a U.S. residence. The DELTA Pro 3 meets the capacity requirement, and when installed as part of a home energy system, it can qualify for the tax credit. It's important to note that the credit is non-refundable, meaning it can reduce your tax liability but won't result in a refund if the credit exceeds the taxes you owe. Additionally, any excess credit can be carried forward to future tax years. For detailed guidance and to ensure compliance with all requirements, it's recommended to consult a tax professional or refer to the IRS guidelines on the Residential Clean Energy Credit.

The image does not show the 8x 125 solar panels but it DOES come with it. You can also get it without the 8 solar panels for $5999.

Do these qualify for 30% tax credit and if so, how? And how does one integrate it into the home as backup home if possible?

Fairly new to this and am looking into getting some kind of backup battery and/or solar.

outside of a short duration power outage, what would be a good use-case for needing this in a home?

$6000 without panels seems better. But still $0.50/Wh, so not the cheapest

These panels are very high quality and 8 for $1000 is an even better deal then the Costco next deal for $550 for 4.
