want to buy this, but my power is so reliable we have only had 2 small outages in 10 years.
Same, I decided to go with something smaller, cheaper, and more portable that I can use for other things ask well. It's the ego power station, and when I have power outages, I just hook up the necessities to it.

Now I have a Rivian that could supply those essentials if I need more, it's a hassle, but the infrequency makes it more convenient for me.

Food for thought.

Quote from davidhood :
I don't really get it. What problem are these supposed to solve that can't be solved by a gas generator for a lot less money?

I have Honda EU2200i and EG2800i generators, but this past Black Friday picked up a Delta 2 Max.

One benefit of the Hondas (among others):
"Limitless" run time, constrained only by fuel availability.

Some benefits of the Delta 2 Max:
-As others may have already said: silent (OK sure, cooling fans if you're cranking the output).
-Can be run inside.
-Can be charged via solar (I have 520W of solar capacity for now, for what it's worth)


In an extended power outage, I can see myself relying on the Hondas during the day, and then using the Delta 2 Max overnight. Zero noise, zero theft potential, I can have it running inside without killing myself. Can run the fridge, router, access points, some lights, etc. overnight, then be charged up during the day.

I'll be expanding my battery capacity, but will probably go with DIY. 48V LFP battery, inverter, etc. You can achieve better Wh/$ doing DIY (sometimes a lot more), compared to EcoFlow or similar all-in-one devices. Maybe not when you're spending $1,000. An EcoFlow device can be simpler and more appealing at that price point. But for the ~$4,000 you'd spend on this deal, you could build a higher capacity DIY system.

For example... ~$2,518 will buy you 2x EG4 48V 100Ah server rack batteries. Total 10.24Wh (versus 7.2kWh from the two Delta Pro's). And you have ~$1,500 left over to buy a nice inverter. For example $1,400 for an EG4 6000XP Off-Grid Inverter (8000W PV Input | 6000W Output | 480V VOC Input | 48V 120/240V Split Phase). Same ~$4,000 for +42% Wh, plus the ability to easily add capacity with other battery brands and types.

Anyway. Plus and minus for both, of course. Those batteries and that inverter have the same 5-year warranty that the Delta Pros do. But the batteries will have a 10 year warranty if paired with a better EG4 inverter. On the other hand, the Delta Pro is "all in one", has a decent phone application, has wheels + handle built in, etc. etc. I see the appeal of that, and have no regrets with my Delta 2 Max. Have already used it once during an outage.

Seconded - and good information.

I've got two very similar setups now: Delta 2 + Honda EU2200i, as well as a bigger hybrid inverter paired with a 5kWh Lifepower4 battery (which I would top off with a bigger Firman 4000/3200W dual fuel generator). Both battery/inverter systems have helped me through multiple outages already over the last year.

No regrets on either system.. but I would trade my Delta 2 for a D2 Max if I could.

Yeah... stuff like this as well as generators are wastes of money for vast majority of people.

You are assuming power outage happens when you are at home and/or your Rivian at home. I dont know how many hours a day you stay at home. I spent less than 5 hours awake at home. The automation can justify the cost

I think a lot of this comes down to where you live, how often power goes out, for how long, and what you need power for.

I live in the Bay Area of California, where our climate is mostly mild, and never would I need power for heat (just put on warm clothing). Our main need in a longer outage is to power our refrigerator. Thus maybe 800-1000 watts of startup, and 150-300 watts for running. Our fridge is new enough that the freezer will stay cold for up to 24 hours, so the fridge part matters. CDC says food is okay for up to 4 hours in the fridge, and 24-48 in the freezer depending on whether full or not.

Most of our outages are between 1 hour and 7 hours. We have maybe 2-3 per year. I've researched but held off on any power replacement options since last time I figured out that if we have an outage, I can run over to the local grocery (which always seems to have power), and buy a few bags of ice or 5-10 lbs of dry ice. Put the dry ice into one of the food drawers, and the fridge will stay cold for a very long time. Ice bags work too, just can make more of a mess.

The only situation I can see having a backup battery or generator would be a long outage of several days. There it might be nice to be able to run a generator every few hours to keep the fridge cold. If I do get a generator it will be a portable 2500-watt dual-fuel unit, and I will run it on propane since that is cleaner and easier, and we always have propane tanks. I frankly don't see a strong need case for any of these solutions since a) worst case we lose some food, and b) we can go to a friend's house or hotel if things stretch out.

Anyway, until batteries come way down in price, running large appliances on them doesn't make much sense. although the tax deduction for 30% of the price (if you get 3000 kwh capacity) does ease the pain a bit.

I wish someone can explain how long it takes to recoup your investment

Forever, unless you have one of those zero pay night plans on electricity, and can offload your daytime use to the battery which charges free at night.

Or with less snark, here's my math.

$4000 for the unit, minus 30% =$2800.

This would pay for 7 times losing $400 of food during a longer outage.

Or it would pay for 7 portable generators.

Or it would pay for 7 nights in a good hotel.

ie a very long payback time. Applause

Only 4K dollars for your YouTube dreams to become a nightmare as RVwhatever. But be smart and it's tax deductible.

I've been looking at the EG4 6000XP Off-Grid All-In-One Inverter with a couple of the rack mount batteries and some used solar panels from facebook market place.

Roughly $5k total cost. If I can offload my network/server rack which uses 200w I can probably save $100 a month (50 cents a killawatt) with an ROI of 5 years. Plus I get the added bonus of having a battery backup system.

The only problem with this dual setup compared to a single DPU is that two DP will now consume twice power just to power their own inverters. I think DPU will end up more efficient.

But of course, DPU's price is higher.

Keyword:
DP = Delta Pro
DPU = Delta Pro Ultra

click the blue "overview" link to see the text copied below:

"More watt-hours at home The Extra Battery can be integrated to your home's wiring when connected to DELTA Pro. These battery units become part of your home's peak shaving and emergency power solutions."

EDIT: I don't see any mention of it in the user manual. That web page comment might be marketing misdirection/lies. https://www.electricgeneratorsdir...578f8c.pdf
It does look like you can set time of use with the powerinsight accessory, but I didn't find anything in the app. One cool thing about the ecoflow is that you can set charge/discharge limits. Instructions are in the ecoflow app's how to video
