Care, the ultra (non plus) can't add expansion batteries.

This is a really good price, this is what I paid about a year, maybe two ago for my Delta 2's with extra battery (which is only 2kwh total) and was 2 units to carry around.

~33c/Wh for an all-in-one 3kWh unit with a beefy 120V AC inverter and solar input is a solid deal. This isn't far off what I paid for my 1kWh Delta 2 a few years back.

Good unit for camper use with the 120V/30A plug. If only the Delta Pro 3 (240V AC) would get near this price....

I have never heard of this model. Can you connect 2 units to get 240v?

Ecoflow website has gotten worst and worse, ads and floating buttons all over.
Also give it a few months and you'll start seeing additional lower capacity models
Delta 3 Ultra 2900 ... units that don't meet specs or lower quality cells thrown in under a different SKU to be sold at HSN/Walmart.

How is this different from the original Delta Pro? Stats appear the same. How many extra batteries can it use?

Does this support pass through charging (charging at the same time you are using it to power some devices)?
