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) ?

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?

You need to price in the cost of BMS and inverter, which is included in Ecoflow's product but would need to be added separately for your DIY solution.

It's not hard, but you'll never be able to package it in a unit this size and keep it relatively portable.

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..).
