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?
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.

Similar question with rooftop solar
I assume to integrate this with home power supply would need electrician, one of the last pages has diagram in manual, would also need another product.
Can we simply use this setup and directly plugin car EV charge cable too ?
You can normally buy small numbers of new panels from installers and individuals on FB or Craigslist if you're building a small array, will be much cheaper than these panels.

These are very very different from residential panels. You can't compare them if you're using these as portable temporary arrays
Correct. 4kwh main unit and 4kwh per additional battery

Your math is a little off. If one unit can hypothetically run your fridge for 12 hours, three units would be 36 hours, not 48.
However, it's a bit off either way if we're being conservative and realistic.
Some fridges, like the LG inverter drive series, are a little gentler on the compressor cycle, but most can definitely crank past 300w. How often they run can vary based on settings and use. Regardless, you need to spec for that compressor start cycle rather than linear use.
As far as capacity goes, the battery may be rated for 4kWh, but you should never account for full depletion. Lithium phosphate isn't as sensitive as lithium ion when it comes to wear, but they are definitely susceptible to strain.
Accounting for all this, a more conservative estimate would be closer to 32 hours if you plan to still use the fridge during that time.
As for the solar piece, that's largely dependent on too many additional factors. Put your details into a solar calculator and you'll get a rough estimate of how big of a system you need versus what these batteries provide (with the consideration of only using 80% of their capacity).
Give yourself a decent buffer and over provision so your system isn't too deficient on underperforming days.

I have a small solar array which only generates 10kW a day during summer, with some lightweight smaller panels for emergencies bringing that up to 12-13kW per day. I have a GMC Sierra EV with a 200kWh+ battery I can power most of my house with, including my AC, that'll last 4-5 days in summer (in Houston) and 2-3 weeks in winter. The synergies work well for helping to power my house and vehicle, lower my costs and even with a small amount of solar some independence.
Some of those above have systems that are smart enough to charge on regular power when a certain threshold is reached (say when it's a cloudy day). Either way, their overall energy cost is lowered because solar provides some of the electricity.
I think the question is how long will you get your ROI? Is it always sunny where you are? How many things can you take away from the normal power and add to the battery circuit? Last point to note that some of those guys arent doing it for the $ but because it's their hobby.

I have a Delta Pro 3, Delta 2 Max, and a few smaller units (River 2 and 3). Having the internet and TV plugged right into the River units meant that the power never went down as we were watching a movie. Those units are small and would only maintain internet through the night OR TV/soundbar/etc for an hour or two. That was enough time for me to run my extension cord from the Delta 2 Max (2kwh) to all of my fridges and other devices.
For 'overkill,' I had the Delta Pro 3 plug right into the Delta 2 Max, which gave me a bit shy of 6kwh of available power. This let me plug in all of the completely optional items (recharge the River units, coffee maker, phone chargers, whatever) and not worry about a thing. This meant that the single Delta Pro 3 was the only one actually using up its battery (and if it were to empty, then the Delta 2 Max would start to work from its reserve of 2kwh).
A standard fridge and freezer would probably take 10% to 15% of a Delta Pro 3's charge over a single night. I had two, and a bunch of other devices, and woke up the next morning to a 42% charge left on the DP3. I have some solar panels on my shed that brought in about 4kw that day, which effectively refilled the battery.
This can help illustrate the utility of these devices without worrying about how they would integrate into your actual electrical panel. They aren't necessarily cheap, but they are built to be relatively idiot-proof.
I'd love an extra battery or two, but they're more expensive than the standard units outside of Costco Next.
A final note- think of these as emergency units, but please be aware that the worst use case of any battery would be powering an electric heater or full HVAC system. A space heater uses 1500w per hour, meaning that a 4kwh Delta Pro 3 would last about 2.5 hours powering one. Propane is still king when it comes to heat, and if that is your primary concern for emergency preparedness, grab a Mr. Heater for a hundred bucks.
I use it to power some ASIC and CPU /GPU combo crypto miners. I also harvest and save the power for 7kw Tesla charging. You can achieve 7kw with the ecoflow voltage hub, got some refurb bifacial and poly crystalline panels to generate a fair amount of power. Let's just say, although the previous owner stripped my Model S of its Lifetime Free supercharging, im still charging for free lol. I was going to purchase a 90kwh Tesla battery to replace the old one , then use the old battery for solar storage, $12k for a 90kwh is more than enough to power a house, maybe even 8 houses. Unfortunately that's not user friendly since Tesla voltages don't follow the standard 12,24,48v configuration of solar harvesting equipment out there, it'll take some number crunching, trial and error to get it down. If you just stock up on this, can bypass all that experimentation and immediate "plug n play" straight harvest fully off grid!
Still it helps to charge my Model 3 with all that excess free power. Maybe build a solar Pergola or carport out of used panels!
Thinking about doing a set up to run my restaurant semi off grid with some sort of transfer switch wired into the main panel.
So yeah plenty of uses, these are handy!

These can be fed into a generator inlet / transfer switch and provide pretty solid backup for virtually everything in your house (with some exceptions like electric water heater, and simultaneously running multiple big consumers at once e.g. electric range + central AC)
