Ecoflow, Bluetti, etc make portable power stations that CAN power a whole home but none of them are ideal.

Extremely expensive, not flexible, stuck in an ecosystem, hard to scale, etc.

A Delta Pro/Ultra I would say is good up to a RV or something because the power demands are not as high and you can take advantage of its portable nature.

Since anything powering your home full time does not need to be portable, your much better off with a DIY system from Victron, EG4, etc.

DIY meaning piece by piece not so much that you have to do the work yourself, as even this system your paying an electrician to install the panel, so may as well pay them (less) to install a big inverter panel instead.

Here are some facts

12kWh "enough for a week" based on the advertisement that is enough for a few hours at my house. I use 60kWh a day on a normal day when I am home.

The average home probably at least 30kWh

The batteries are 6000Wh each costing over $2000 each with a maximum expansion point.
DIY you can buy a 5000Wh rack mount battery with more features and protections built in for under $1000 so if you scale up to say a 60,000Wh system just the battery alone

Delta Pro Ultra 60,000Wh = ~$22,000.00
DIY 60,000Wh = ~$10,800

That alone will pay for your install costs, stronger and better inverter, and even allow buying a backup system (or better solar)

Then features, the Ultra cant do things like EPS (Emergency Power Mode) for the 20ms UPS feature while also in self power mode to make use of solar power.

It also has a pretty terrible limitation for pass thru power.

This was my first big deal breaker and why I went with something else, as this is a very standard feature for a mid range hybrid inverter.

72000w also is not even strong enough to run most homes with HVAC. so you would need to buy two of these to get enough power, and that makes the cost start to go sky rocket (and you have to buy additional inverters to expand battery capacity as well)

I can keep going, the list is pretty long but I think you get the idea.

That said I own over 12 Ecoflow Power Stations and I pre-ordered the Bluetti Apex 300 so I am not biased or hating, just honest and transparent and I don't drink the Ecoflow Koolaid like most people on the respective FB/Reddit groups.

As a matter of fact, they hate me because I keep sharing ideas on how to hack their equipment to save money or recently even called out an inverter quality issue they have.

https://youtu.be/0fvpc5QyYHk?si=E996QIr9M3Ty9Sdv
I'll try to add a little content based on my experince with an expanded setup of this deal. I currently have 2 EF DP inverters and a total of 4 EF DP batteries all hooked up into a SHP2 that I installed myself - they have been up and running for >2 months now and have served me perfectly for my setup. Before going further, I'll simply state that ViciousXUSMC seems to really know what he is talking about in terms of pros/cons of the EF setup vs. alternative DIY setups and if you are starting from scratch, you would be wise to do some more digging before spending your own $$$.

The primary use for my setup is to serve me during a power outage at home AND to be as seamless as possible so that if I were not home, my wife/family wouldn't really need to do anything to continue living 'normally' --- at least for ~10-20 hours. I do have a tri-fuel generator that I run on NG which I wired to an outlet that sits between my main panel AND the SHP2 panel that both have lockout switches installed. This gives me flexibiilty to either power up the secondary circuits that I did not move over to the SHP2 and/or re-charge the EF DP batteries in the case of an extended outage. This is something that I would likely need to be home for IF it were needed as I don't think anybody else in my house could figure it out.

I have added 4x 400w solar panels on a ground mount as a 'fun project' which do an 'ok' job of recharging the DP batteries on a daily basis. The SHP2 will then use the excess power collected in the batteries to power ALL fo the circuits on that panel until the overall battery % is depleted to 50% (this is configurable, but I don't ever want to have <50% charge in case there is an outage). This saves me a few bucks every month off of my electric bill --- while not my primary goal, it is enjoyable to track this throgh the 'very solid' EF app. I should note that the switch from grid to battery power using this mode is seamless -- nobody would ever know when the SHP2 transitions from one power source to another unless you brought up the app.

Additionally, there is a feature called 'storm tracker' which will automatically charge up all batteries to 100% (using grid power) within 24 hours of a storm approaching my area. This has happened on several occassions and would maximize my battery storage should power be knocked out during a storm.
I cannot speak to how seamless some of this functionality would operate in a DIY system, but for my specific needs it works really well. Did I spend more $$ (possibly a lot more??) for my EF setup that I would have using a DIY, almost certainly "yes", but the system is very slick in the way it is setup/connects/etc -- I would have had to invest more time learning how to best setup and organize a DIY system (i.e. buy a rack -- maybe several, buy a bunch of low AWG wires to interconnect things, etc.).

In short, I am quite pleased with the overall functionality that I am getting out of the system and the overall ease of setup and use. I'd advise anybody considering this or a DIY setup to do a bunch of research before deciding what is best for your needs.

EDITED NOTE: I actually purchased this particualr deal from Costco at this price the last time it was offered, but was able to snag 2x additional batterest at $1500 ea. from the Home Depot deal ~1.5 months ago. If there is another sale on batteries at a similar price point in the future, I'll consider further expansion of my system. The reason I mention this is that there are ways to save some $$$ once you enter the EF ecosystem that 'should' save you more $$$ over the typical prices -- obvioulsy, you need a little patience and to NOT have an urgent need for this to play out.
this guy is real good, start with him, he has several builds and is highly respected in this field https://www.youtube.com/@WillProwse

can this be a good solution primarily use at home and bring it to RV/boat to power electric need on the road
it's very heavy. the inverter plus two batteries weighs around 300 pounds. all depends on how much space you have on boat/rv and how much of an inconvenience to wheel it out and lift it into your boat or rv. dunno if you have a yacht or a tiny motor home.

Seems like EcoFlow is more about convenience than long-term scalability or cost-efficiency. For someone who doesn't want to go fully DIY but wants something better than a plug-and-play.
you can chain three of them together with 5 batteries to each inverter, for a total of 90 kwh battery capacity. so this is plenty scalable. most folks don't need more than 90kwh battery storage. your only argument now comes down to price.

obviously there are cheaper solutions, but diy is a lot more complicated to set up, and typically not portable, so yes, you are paying a premium for the convenience and portability factor.

surprise, surprise, you actually have to pay more for something more convenient and easy to set up, which is portable. some folks are willing to pay extra for that, because time is money, and they don't want the headaches of wiring up diy or learning how to wire up diy. of course one can do diy cheaper.

we shouldn't be presumptuous and assume we know what's best for everyone else. for example, some folks are renters and do not own their own home, so the ecoflow system might work better for them in their situation, where they cannot easily modify the electrical panel in their dwelling by installing a diy setup.

granted, this particular deal does come with the smart home panel 2, so it is geared for those who can make modifications to their electrical panel. however, perhaps someone is a renter now, and intends to purchase a home in the not too distant future. they could put the delta pro ultra to work without the shp2 for the time being, and then after they purchase a home, they could install the shp2 permanently.

Yeah totally. Between the paid shills and the fanboys trying to justify their $7k setups, it's almost impossible to get real info in those groups. Your breakdown here is way more useful than the usual "life-changing product" hype comments.
for some folks, $7k is not that big of a deal for something that can be up and running in less than an hour. you can use the delta pro ultra right away, while you get around to installing the smart home panel 2 later.

some folks spend a lot of time and effort learning how to install diy, and others use that time to make more $, so they can afford more turn-key solutions. neither approach is necessarily wrong.

But if you want to spend all that money on an Ecoflow system be my guest.

if you want to spend all that money on a victron, be my guest. they do make quality stuff. i own and use some. ecoflow is expensive, victron is expensive. they both have their pros and cons. isn't it nice that we have choices.

i wouldn't mock someone for paying more for quality victron gear, just as i don't see the point in harassing folks who spend more for the convenience and simplicity of ecoflow.

no need to be a crusader. just be content to let folks buy what suits their needs/application best. i happen to use a combination of victron and ecoflow products. part diy, part plug-n-play.

If im a complete newb to this, i do a lot of wiring in my house when it comes to 110v but im not super experienced. Like a shade tree mechanic.

im looking to spend around $1-2k to start. with a small system that would help absorb some of my electrical use during the day. so i think thats grid tied system? If possible to add a medium sized backup battery(s) that might help me power some electronics for a few hours when the power goes out would be nice as well.

are there any kits someone would recommend or great install videos for a starter kit that has future expandability?
you have to be very specific about exactly what you want to power, and for exactly how long. then it will be easier for folks to help you. a fridge? tv? lights? ac or furnace? electric heater? tell folks *exactly* what you want to power, and for how long you will need this backup power, and it won't be too hard to recommend something that will fit your needs.

Same actually, but the big whole home setup is going to be EG4 FlexBoss 21 for me with the Gridboss MIT

I'm not a crusader or a salesman, just a voice of reason that people can choose to listen too as an alternative to where many places have only bias.

Horrible deal, I bought the same setup for around $6000. Deal ain't slick at all...
yeah, i think it would be a thumbs up for around a thousand less (considering costco's return policy), but not at $7200.

Quote from np1050 :
Old used Chevy Bolts have a 60kwh battery and cost about as much as this setup. But in addition to the pack, you get a functional car. I'm struggling to see the value here. I wish there was a way to repurpose some of these older EVs to run a house and serve as a backup battery pack
i'm guessing you can hook up an ecoflow alternator charger to the 12v battery on the chevy bolt, and feed a steady 800 watts to a compatible ecoflow power station. i assume the high voltage battery in the bolt will continuously feed and keep the small 12v battery charged up, while you pull from it. unfortunately, the delta pro ultra is not compatible with the ecoflow alternator charger, but the delta pro 3 (4,000 watt inverter) and delta 3 plus (1.800 watt inverter), are compatible.

otherwise, i assume one could hook up a 12v inverter to the chevy bolt 12v battery, and run loads or charge a power station that way. i don't know the max output one can extract from the chevy bolt 12v battery.

but in an emergency, i'm sure people use inverters or alternator chargers to use the chevy bolt to provide backup power.

Quote from saint327 :
Having stacks of batteries and inverters was what I looked at a couple years ago. These days have actually started looking at getting an EV with V2L capabilities and a transfer switch. Can power all your 120v things for days, plus you get the EV. If your home has gas your golden, otherwise just need a single burner portable induction cooktop or just use a grill to cook food. Fridge, freezer, lights, fans, tvs, internet, etc. essentials.
sure, if you're willing to pay a lot for an ev, it can be an excellent emergency backup source. just be aware, that oftentimes the insurance on an ev is more than a comparable gas car. so, there are many variables to consider. the most important factor probably is whether or not you can get an ev tax credit. if the tax credit goes away, with the extra cost of insurance, it might be more difficult to justify buying an ev just because it serves as a backup source of energy in an emergency. what if a lot of folks buy evs and then the grid goes down? not going to be a lot of happy campers in that situation. see the creepy julia roberts netflix movie leave the world behind (2023), where all the teslas are dead on the road, all piled up. perhaps a hint of things to come.

i would only want an ev if i had an gas car as a backup, and i would also want to install a solar system to charge my ev, so i could still charge it if the grid went down.

Quote from slickjunkie2 :
Are transfer switches manually operated? Does someone have to be home to flip the transfer switch?
there are manual and automatic transfer switches. the smart home panel 2 that comes in this ecoflow bundle is an automatic transfer switch. after it is installed (probably have to pay an electrician a thousand bucks or two), and connected to your main panel, when the power goes out, it will seamlessly switch over to the ecoflow, which will power your critical loads. the app allows you to both monitor and control which circuits in the ecoflow subpanel are powered on and off, with the touch of a button. very slick, but not exactly cheap, especially after you factor in the cost of paying an electrician to install the smart home panel. unless you can do it yourself. but, you can offset some of the investment if you have time of use electricity rates in your area, by running off battery when electricity rates are high, and recharging the batteries overnight, when rates are low or even free. or, if you have a solar system installed, you can run some circuits (you can choose which ones in the app) off-grid to reduce your dependence on the grid, and lower your bill.

if you don't have TOU electricity rates in your area, or you don't have a solar system installed, then this is an expensive backup solution for only the occasional emergency.

this system becomes much more palatable if you can take advantage of the 30% renewable credit on your taxes, and you have TOU or solar to reduce your electricity bill.

the new flexboss offerings from eg4 are great for diy-ers. much quieter than their predecessors. i would never get a 6000xp or a 12000xp, because they are just plain too noisy, while the ecoflow dpu is nice and quiet.

however, now that the new flexbosses (18 and 21) are much quieter, they are much more appealing as a diy alternative to the delta pro ultra.

enjoy your eg4 setup. i'm sure it will be really nice.

$7,200 is an expensive way to store about $1.56 worth of electricity (at the average US residential rate). Kinda like storing food in solid gold containers.
This is a valid consideration, but the calculation varies by area and individual use case. I'm in Northern California (Pacific Gas and Electric), and I would use $0.40 per kWh, so this unit stores 12kWh, or about $4.80. If I store-deplete every day, then that's $4.80 * 365 days, or $1750/year. This can potentially pay off in 4 years, plus serve as back-up for blackouts etc.

Sure, there are other costs and factors, but the point is it's not just to save $1.56 of electricity. Personally for me, I'm looking for "pay back period" of 2-3 years, so I'm probably dreaming. Smilie

ah. BMS. that's probably the term I needed to know/learn about today.

Thank you. Cheap all in one batteries don't have a solid BMS. Smilie

Has anyone set this up to benefit from time of day utility rates? ConEd has peak/off-peak residential plan with much cheaper rates in the night. Can I charge this then and switch to using these during the day seamlessly? I have a new construction all electric house with geothermal heat/cool, heat pump water heater and heat pump dryer. Also I have a 50amp EV charger which is connected to the utility and I get 10c off per kWh for charging between midnight to 6am. This may be breaking utility rules but just curious if this can charge from a J1772 or NACS.

Can I use it to power the house all the time and charge it during super off peak hours (12-6 am)?
