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.

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

90kwh and 21.6kw output not enough for a home? Yeah it's expensive, but to say it's not enough power for a home is bs

Not sure why you are quoting me, I never said that.
Serious go read what I posted.

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

I am on all the groups, every single day someone has a major problem on the Ecoflow groups.

Hell they just pushed bad firmware to a ton of people earlier this week.

By comparison, I see almost no complaints or failures in my Victron group, EG4 group or DIY groups.

It's a huge gap, but like I said to ask this question in an EF group or something and you have paid off group members, brainwashed group members, etc so you won't get true neutral information there
1) Thanks for pointing out DIY is infinitely cheaper than Ecoflow. I figured it would be, but the $$$ quoted was a lot more than I was thinking.
2) Having bought "out of the box" LFP batteries from other places -- Ecoflow unfortunately is the most "stupid proof" out of all the devices I've owned. I still have to 'shill' for Ecoflow even though it's VERY obvious they've gone down in quality.
3) River 3 can't power usb C (high draw 45w, laptop) + both USB A ports in use at the same time. There's some weird issue where my laptop stops charging.
River 2 - no issue. Not sure if software or hardware. I continue using the River 3 over the River 2 b/c of stats of how much electric I've "saved". I like that data. I just don't charge my phone if my laptop is on lol


Daranener and pecron batteries - I'm still annoyed at their blatant lies about customer service. There is none after purchase. Both of these devices suffer from overdraw/no battery stoppage in case of 'overuse'
What I mean from that is - I had a pecron fail because I wasn't watching and it drained 100%. Unable to revive after attempting to manually charge and solar charge. No safety protection.
Daranener - it MIGHT have some sort of very minor 100% drain stop but upon reviving, the battery charge/life indicator no longer works properly. 5/5 bars = full , 3/5 bars = almost empty. Battery gauge is not accurate at all.

You also can't use the battery and charge (without damaging or causing 100% drain issue on either of these devices.

Whereas Ecoflow, you can safely do so without issue. I've been able to full drain Ecoflow and also solar charge/use battery at same time without issue (software smart enough to stop charge once battery depleted even though it's on solar)

Until another competitor comes out with "stupid proof" software with their batteries (I suspect this is the most expensive part of the process), Ecoflow will still reign supreme in many circles, even as their products take a hit in quality.

DIY is cheaper, but plug and play systems aren't competing on price.

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?

Looks like a beast on paper — 12kWh, 7200W output, and fast solar+AC charging. But at $7,200, I'm wondering: has anyone actually used one of these in a real home setup? How's it compare to something like a Tesla Powerwall or Bluetti system in terms of reliability and integration? Curious if this is truly whole-home ready or more of a high-end backup solution.
I'm using one of the HP1 with older batteries. I am Vendor Locked. It's okay. I sold Cisco once. Installation is easy but expensive to have certified using a master electrician.

Offgrid I did it. Ongrid I hired. Out of my league and/or Just In Case. AMA

I cannot do DIY. I prefer the design of a finished EcoFlow systems rather than most DIY devices clustered together. I like the software features of the EcoFlow on the phone app too. I bought the Costco bundle deal with panel. EcoFlow said they would refer me to local electrician for install with permit. Federal Tax Credit will help defray some cost. Thank you to OP.

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

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.

Are transfer switches manually operated? Does someone have to be home to flip the transfer switch?

$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.
you do realize, that is the nature of batteries? and yet, people still need them, and buy them. it would take at least 250 AA batteries to store 1 kwh of electricity, which costs me around 15 cents from the utility. how much do 250 double-a batteries cost? $100, give or take? so, with AA batteries, you are paying around $100 to store just 15-20 cents worth of electricity from the grid. and those are one-time use, disposable batteries, not the rechargables, which cost a lot more. and these ecoflow batteries are able to be recharged thousands of times.

nevertheless, this deal is lukewarm at best, since most people have to pay tax at costco, pushing this close to $8,000 out the door.

would be a better deal worthy of thumbs up, if it was $6,200, rather than $7,200.
