The limitation is that _either_ the 240V inverter is working, OR the 120V inverter is working. If you've got a panel wired to take 240V in like the power company delivers and split it into ordinary house electricity, then that limitation is not a big deal... why plug stuff into the front of the battery rather than just light up the plug in the wall? If you want to plug a 240V thingy into the front of the battery AND plug a 120V thing into the front of the thing and run them both at the same time, you're out of luck, you cant. But if you use the 240 to light up your house's existing plugs, you're OK. It's not that you can't run your light bulbs and your well pump at the same time... you can't do that by plugging stuff into the front of the battery.

Why would that promo apply to a sale from another vendor (Costco) ?

I am interested in one of these to provide power to a detached garage. The garage was original fed from the house with 120V power but underground cable has a ground fault somewhere. Wondering if there's a calculate to check if this setup would have enough power to operate garage door opener, lights and a few other things in the garage.?

Quote from ChrisH5547 :
The DP3's appeal is that it has the 240V generator out plug that can connect directly to a generator in port on your house panel and light up the whole thing rather than just half of it... and can power your 240V stuff like well pumps and such. For me, that was the killer app that sold me on one. The question about having the pair of them is whether there's a way to double the effective inverter wattage so that it can handle 8kw loads rather than 4kw loads. I'm not sure if that is a thing or not. If it is, that would be awesome.
Actually, it is in the description:
A single source to power almost all of your essential home appliances. Power high-demand appliances with robust 8000W and dual 120V/240V capabilities. Keep your kitchen buzzing and essential systems like garage doors running, all powered simultaneously and reliably by EcoFlow.

So I think it does double the wattage when connected.

It makes sense since this bundle includes the hub that connects the 2 together. Otherwise, what's the point.

The backup batteries for garage door openers are tiny. This is overkill for that. Unless you're also running a fridge or freezer.

The problem with this is that if something goes wrong (and there is def a chance for something to go wrong with Ecoflow) then you're screwed by splitting it with a stranger. Costco is not going to take a partial return. The benefit of Costco is their return policy but you throw that away by splitting it.

This thing's got enough power output capacity it won't even break a sweat until you start throwing major 240V consumers at it like an oven/range, welder, or central air - and even then, it'll run a lot of that stuff.
Quote from RedZoneOS :
Question for the experienced folks - lifepo4 batteries of similar capacity can be purchased for less than 2k. Guessing another 1k for the wiring/hub etc

Is the 3k estimate comparable as DIY to this 5k plug n play option? And if yes, 2k price difference is a ton...is the diy option that much more difficult/challenging?
Quote from sdsnake :
Mount everything on a dolly and you are good to go
One thing a lot of people fail to consider when DIY'ing their own using cheap components is that these units are actually UL listed. Use non UL parts on a DIY setup and it ends up burning your house down? Good luck getting your insurance payout.

Additionally, there's more to these than just a battery/inverter. There's also the AC charge controller, solar charge controller, and all other I/O (e.g. USB) in one tidy little package, not to mention the app which is pretty handy to have for monitoring / automation.

Lots of assumptions on battery range from an EV. Current Tesla model 3's (after November 2021) have a battery capacity of 82kwh so this will provide you a little under 8% if you completely drain the ecoflows (wouldn't recommend doing that). This is also assuming that your charging/discharging efficiency is 90% for both the ecoflow as well as the model 3.

1.2 KW Lifepo4 battery on Amazon with built in BMS of 100 amp is around $170. Plus throw in an inverter charger for $600 and it would be still exponentially cheaper than Ecoflow.
Get " Ampinvt 3000W Peak 9000W" which is a pass through inverter with auto switchover.
$2500 per 4 kwh battery for Ecoflow. 4000w output, 1800 watt charging on 120v (assuming 15 amp breaker), 4000 watt charging on 240v, 1000 + 1600 watt MPPT charging on solar.

4*$170 = $680 for 4.8 kwh battery.
$50 for wiring (conservative estimate)
$50 for USB chargers
Ampinvt inverter choices:
3000w 24v: $525, maximum 900 watt charging, no solar. Total: $1305
5000w 48v: $715, maximum 1700 watt charging, 240 volt input only, no solar. Total: $1495
6000w 48v: $835, maximum 1700 watt charging, 120 or 240 volt input options (not changeable after buying), no solar. Total: $1605

If you want to add solar charging, there are two options: PWM or MPPT.
PWM charger: ~$50 for up to 2900 watts, lose up to 25% of power depending on setup and conditions. Also far more complicated to properly set up.
MPPT charger: $100-150 for up to 2800 watts.

So yes, you can save up to half by DIY (you can actually save more by buying your own cells), but that requires sacrificing many of the features bundled in the Ecoflow unit. Once you get up to the same feature level, it becomes a question of whether or not saving $800 is worth the time investment (probably at least one whole day to put everything together) and a significantly less convenient form factor.

However many miles you get with ~8% battery. Or more accurately, however many miles you can get with 6.5-7 kwh.

I think it's more like 10 miles. On an Anker 3800wh capacity unit they added 10 to a Tesla. It's basically the same capacity as this Ecoflow DP3 so should be around there.

I'm just using my chargepoint app as a reference and did not do any calculation. I added 7.0kWh for 31mi for my MY2023LR

I think for the money, I would favor the DP3 if anything for the flexibility of having each unit by itself being able to do 240v.

Now the DP refurb has gone as low as about 1700 each, which then might make the cost savings worth it if (big IF) it qualifies for the tax credit. as a refurb (jury is still out).
