EcoFlow's DELTA 3 Ultra looks like a strong value for a single 3,072Wh power station, especially for camper, vanlife, and home backup use. The 120V, 30A TT30 output, 10ms cutover, and hi and low voltage solar input make it appealing for larger loads and solar setups, and the price compares well with older Delta 2 purchases. The main limits are the 800W solar cap, 60V input ceiling, and the non Plus model's lack of expansion battery ports. EcoFlow's confusing product pages and talk of future feature paywalls add some caution, but it still stands out as a compact all in one option.

  • The deal price works out to about 33 cents per watt-hour for the 3kWh all-in-one unit.

    Caleo

  • The unit supports hi and lo voltage solar input along with EV bypass options for flexible setups.

    HexiumVII

  • The solar input and inverter combination can suit camper use with a 120V 30A plug.

    Caleo

  • A coupon code can work on Amazon and stack with an additional 5% cash back from Prime Visa.

    tlu448

  • Solar input is limited to 11-60V and 800W max, which can make residential panel matching difficult.

    DocuMakerDocuMaker

  • The Ultra (non-plus) model reportedly cannot add expansion batteries, limiting whole-system growth.

    FrankP3SharpMarmot822

  • EcoFlow's website experience can be unusable due to excessive pop-ups and ads, which can hinder research and purchasing.

    LeakyAneurism

  • Home backup compatibility can fail, since Home Connect and batteries reportedly required two power legs and still would not connect after adding a second battery.

Quote from tivoboy View quoted comment :
Well one has to really go up to the delta PRO lineup to get 220/240v, but the delta 2 max's are certainly cheaper and lighter than this, although for $/kw this is arguably the cheapest, but it's also heavier carrying around 3kw in one place vs. 2kw. If I wanted 3kw (for the tax credit) and wanted it in one unit for ease of deployment and the size didn't bother me, this puppy is pretty darn good for that. And with the 10ms cutover it's serve rack certified, whereas the delta 2 and other series I think are "only" 20 ms cut over capable, slightly better in actual testing.
You're awesome - thank you!

I pulled the trigger on this. I had the Delta Max 2 which had a 2400W continuous 3600W surge capacity. Hopefully is enough to power my log splitter!

lol. They still think Black Friday is a thing. Def not SDers.
I have tracked Black Friday prices for quite a while. There are exceptions for some loss leaders, but in almost every case I could find, the best prices were typically a month before Black Friday. The prices increase towards Black Friday and then the discounts you see on Black Friday reflect the inflated price mid November. So generally first part of November is kind of the best time to buy.

Ecoflow website has gotten worst and worse, ads and floating buttons all over.
Also give it a few months and you'll start seeing additional lower capacity models
Delta 3 Ultra 2900 ... units that don't meet specs or lower quality cells thrown in under a different SKU to be sold at HSN/Walmart.
Their website is an absolute disaster. It is just visual diarrhea. Ublock had 180 things it blocked and was still counting up. Even after turning it off, it just crapped pop-ups all over the place. Who thinks this is a good idea? It's almost as bad as Temu. Completely unusable. I just gave up.

Anyone know how long this would power a basic modern day 23 cubic foot fridge/freezer combo? That's all I would be hooking it up to in case of a power outage. Thanks
I have a 20-year-old fridge and a 1 year-old fridge:

20-year old: 105w average over a week of measuring, but: 700w peaks during defrost and 1500 watt momentary surge if compressor cycle power is lost then restarted. Use the 105 w average to assess against wh capacity of power station

1-year old fridge: 71.5w average and I never saw large peaks like the old fridge

I measured these using a Kil-o-Watt meter over several days to catch all the different cycles.

so a 3072wh PS would power the old fridge for a little more than a day, about 29 hours; it would power the new fridge for almost 43 hours. Actual times are probably a bit shorter for realistic charge/discharge levels.

Hope this helps

Except ecoflow units wont turn on or charge below 40 F, and 4600 kw mass is gonna take forever to heat up in the winter.

Product probably works as individually pieces, but support really sucks. I purchased a home connect system and battery and it wouldn't work because it needs two legs of power, even though they sold the product as if is a home backup system. Then, after talking to support, I bought a second battery (and these things aren't cheap,) and it still didn't work because it didn't have a way to connect the second battery. So, I still don't have a whole house system -- just two batteries and a worthless home connect system.

Technically based on their current naming conventions I think it would be called Delta 4 Max Pro Ultra Plus
