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) ?

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.

I would like to know this as well, because it if doesn't then why bother getting 2? It would be cheaper to get an extra battery to increase capacity. I guess if you have 2 separate generator outlets for 2 different breaker panels in your house?

The fact that this brand new release of Delta Pro 3 are so dramatically being discounted, shows that Ecoflow is not selling as fast as they expected. Not surprised with the 120V or 240V limitation (you can only use one or the other but not both at the same time). For that kind of money $5K, the Delta Pro Ultra IMO is a better buy without the 120/240V limitation. And you should be able to find it cheaper (but 6100Wh/battery) at around $4100-4500 and with no sales tax (off-grid, Wellbot, etc..).
Is the limitation for both input and output? Can you output 240v and charge via 120v AC at the same time? The use case would be using a gas generator during the day to top it off. I think the Anker one does not. Not sure about the DP Ultra or this.

yup... I know too little about phase magic, and i'm sure the question is whether the inverters in the two boxes can do the right phase magic to double the load they can handle.

What is the weight of just one of these? I looked on the Costco page and at Ecoflow, but am not easily able to find the weight of a unit.

Can you clarify with what I was asking. Can you power 240v devices while charging the dp3 with 120v ac.

Haven't tried, so can't say. Can't experiment b/c my panel has an interlock and it is the only thing I can feed the 240 into. If the interlock is switched to gen input, I can't charge the box with 120. Well, maybe I can run an extension cord to an outlet to make a feedback loop and have the box try to charge itself... but I've not tied that and probably won't.

Not that hard.. I'm surprised it would save that much have to compare to charge controller and inverter
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.

It's 113.5lb for one unit. On the Costco page, it's in the Specifications section.

These are a bad idea. Keeping them balanced becomes an issue, Ecoflow now makes one big unit that has the 240. See the 8-Bit Guy video.
