I wish they'd stop advertising these as "whole home" backups. They're not. 7.2kWh won't get you far. For reference, the average home in the US uses 28-30kWh a day, on average. Yeah that includes electric dryers, ranges and such, but even if you avoided using 240V (e.g. high consumption) appliances, you still wouldn't get very far. Then when your battery is dead, do you haul all 200 lbs of this thing somewhere that hopefully has power to charge?

That's not to mention the outrageous price for what you get - 7.2kW and 7.2kWh. Another $1kish will get you a 20+kW NG standby generator with 200Amp transfer switch, that will run essentially forever.

Yes I understand these have their place - if you need silent power, and your power demands aren't extreme, these might work, but they're a super pricey solution.

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.

Why stop there? There are so many ways to "profit" from tax fraud!

Quote from ThriftyKitten3507 :
My breaker panel has an interlock kit that the previous owner installed to use with a portable natural gas generator. It has a plug outside the house to connect the generator but I don't currently have a generator. Would these work with that setup? Or will I need an electrician to install something else?
Is the plug 50A or 30A? This comes with a 30A. You can get adaptors, but it's an additional cost.

Costco also has the 2-pack of Delta Pro Batteries on their Costco NEXT site for $2599.99.

https://costco.ecoflow.com/produc...ra-battery

That would give you a 10kWh system for $6600.00.

Quote from s2000fsu :
Each one of these Delta Pros can handle 1600w of solar. So between these 2 units, you could connect to 2 1600w arrays. Yes the solar panels would need to be permanently mounted somewhere. These also have a pretty good 5 year warranty and are LifePO4 batteries. You could buy a Smart Home Panel 1 (or the new 2 version that just came out) to automatically connect this to your home power as they act like smart transfer switches. You could think of these as a cheaper Tesla Powerwall. This could be a way to DIY solar at your own home, without having to interconnect to the power grid.
Right? I don't understand why people are comparing these to a gas generator. It's like comparing apples to oranges. They should be comparing these to a tesla Powerwall or other type of battery storage, and when you do you will see this is cheaper per KwH.

I mean, if you're going to do that why not just say you bought 10 of them? Tax fraud is tax fraud.

Who's to say which system you end up keeping? Wink

You'd need to install all 10. Wink

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?

Noise, the ability to use them inside, using solar, to name a few.

Quote from superslickz :
Not sure what you mean, but here is one scenario. Let's say 30A and 7200wH is enough to power your house during the daytime. Then let's say you have an unlimited free nights power plan. Then you could charge this at night, use it during the day to power your house, rinse and repeat.

Is that what you mean?

Again, it all boils down to whether 30A, 7200wh is enough to power your house. If you have central AC that will be tough in the summertime.
Exactly. Peak shaving is charging during a lower cost schedule and using the power during the peak hours.
