I know this is still wildly expensive but the same 2 battery configuration on Ecoflow's website is $8798.

If you're in the market for one of these this price for 12kwh can't be beat.

Batteries won't need to be replaced in 5-10 years. Lithium iron phosphate batteries are good for 10 years of full discharge every single day.... And at that 10-year point, they still have 80% of their capacity left. So if you ran this every other day to near empty, and recharged to full, you'd get 20 years out of this battery and still have 80%.
·
The price of batteries is dropping about 5% every couple of months. If you're going to spend this much on a battery, much better to get solar first. You can DIY a nice solar system with portable generator back up for the same price and still get the 30% rebate. Unless something happens, the price of these will keep going lower and lower. Better to wait
·
Whole house generators are roughly $10-20k installed. They'll run for much longer. They will be louder.

This one qualifies for a 30% tax credit and will last 10 years

To be fair the bigger players Tesla, Enphase actually do provide 10 year + warranties.
yes, but isn't their price so inflated that it covers that extra 5 years of warranty?

Quote from GreenRose9133 :
This has a capacity of 12kwh so you can run a 1000w load for 12 hrs. It also has a max output of 7kw so it will not run your ac. A natural gas generator will have more output to start heavy loads and will run continually untill you need to change the oil or the gas supply gets interupted.
simply putting a soft start on your ac will enable it to be ran with the ultra, among other batteries.

Quote from derce927 :
How does this compare to whole house natural gas generator? About the same price. What happens when batteries need to replaced in 5-10 years ? How much do those cost
Was going to ask the same thing. A 14kw natural gas powered unit with transfer switch runs about $4700. People are mentioning you need to factor in install, but you'd have to factor in installation with the battery unit too. As far as I can see, the battery unit can output only 7200w, while the generator is rated for the full 14kw (double) output. The battery unit would run the whole house for a few days, but the NG unit will run indefinitely, as long as there's gas to power it. Same with lifespan... The batteries might last 10-15 years, but so will the generator. If properly cared for, probably longer that even that. I'm still trying to figure out the allure. I suppose it's quiet and can go hand-in-hand with solar, if you have it, but the increased cost doesn't seem to add up for me.

Or maybe not even necessary for soft start: I have a 4Ton 17 SEER central air unit, and it peaks under 7 kW on startup. I understand other items could be running too, but specs for Ecoflow DPU say it can peak at 10 kW for short times.

hard to say a powerwall is $2300 more than this, is rated for daily use and has greater continuous output. Enphase is offering 15 years or 6000 cycles, their 10kwh option is around $6k.

Tesla currently requires installation which they seem to go back and forth on but if you want this thing integrated into your house you are going to need the optional sub panel anyways.

This is kind of tempting.....cheaper then a Tesla Powerwall. Will have to do a side by side comparison.
I did a quick research as I'm in the market as well. For me I'd need 2 Powerwalls which comes out to 27Kwh, installed and permitted is $15K (w/ Federal tax credit) from Tesla rep. More robust, you can connect existing solar panels on your roof, better integration to your house (cleaner install on the wall). If you already have a Tesla, one less app to manage as you can monitor your home within the Tesla app.

To match Powerwall, you'll need 2 of these Pro Ultra's (total 24Kwh), still need to get the smart home panel (add $$) which will put you close if not even more than the Powerwall system. Not sure if you can get this qualified for the 30% energy efficient tax credit. Advantages are, you can probably DIY this install, can bring it with you if you move, can start small and build up. Also, unsure if you can route existing roof solar panels if you already have one, and this will probably eat up some space in my garage compared to Powerwall.

That's cheap for 2x powerwalls. What state? PNW, that probably runs $18k-$20k installed.

You realize he's talking after 30% Fed credit right? Here in New England it's $17500 for 2 PW and inverter then $6k install.

This looks so tempting. I just dont know if I can get this to work for my setup.

I would love to get some advice if anyone feels up to some knowledge share.

I have 39 solar panels with enphase inverters that is grid tied to my current 200amp panel.
I was thinking of setting up this panel 2 with essential breakers like fridge, well pump, water system etc and then have the delta pro ultra be a backup or UPS for the subpanel. I have frequent electricity drops (2-5 seconds, sometimes several minutes).
I also wanted to know if this would either be grid charged or solar charged or even generator.
As far as I can tell it would be grid charged or generator charged and would not charge from your existing panels. You could buy additional panels to charge this unit directly for extended, multi-day use, which Ecoflow sells. I have a similar 32 panel setup with older Enphase inverters which are not compatible with the Enphase battery and am looking at this unit. The biggest drawback I see is the lack of extended-day use, but for 1-2 day outages it would be fine to charge from the grid and discharge to the house for TOU arbitrage. I was hoping Lucid would activate V2H ability to obviate the need for this.

Correct, total was $21K, less 30% fed tax credit.

I'm trying to figure out how this capacity is useful. My house uses approx 40 kWh per day during the summer so I don't see this as a realistic generator alternative.
