You could buy a 2nd unit. And I have. Ended up buying an expansion battery for that as well. If you're looking at expanding your run time, Like running a refrigerator for a longer period of time. Then it's good to have an extra battery. You could just piggy-back two of these units together by plugging one into the other. But then you would lose more watts by having both inverters running at the same time.

Can get a free 45w solar panel with this. Nowhere near enough to charge the actual unit but saw it as an option

I couldn't get the promotion of the 45W Solar Panel to stack with the coupon code. So YMMV

I remember buying this exact set a couple years ago on a slick deal from amazon for $850. Is still running perfect to this day. Having this set really taught me the value of having a battery power station. Unbelievably helpful in an outage , along with a generator. I don't know if this set is a good deal at this price in late 2025 or not. Still, it's a great lightweight system and nice to have

Why run the extra battery and not buy a second regular Delta? 2?

Code doesn't work for me - though I can get the free 45W solar panel - so not know if this cancels the OP's code.

Amazon US has the EcoFlow Delta 2 + Extra Battery on sale for $709, use Promo Code LLNQ3YKL at checkout for an extra 5% OFF to bring the price to $673.55 + applicable taxes. Free Shipping.

About this item
  • Expandable Capacity. 1-3kWh expandable capacity to grow your storage to your needs. Add on the DELTA 2 extra battery to reach 2048Wh, or add on the DELTA Max Extra Battery to hit 3040Wh. Great for home backup or everyday appliances.
  • Huge AC Output. 1800W AC output means you can power more than 90% of your home appliances. Or, try plugging in up to 15 devices at once. Unlike other brands, DELTA 2 can prevent overloading from devices up to 2200W thanks to X-Boost technology.
  • 7x Faster AC Charging. X-Stream tech means that DELTA 2 charges 7 times faster than the competition. That's 0–80% in just 50 minutes and 0-100% in 80 minutes with AC input.
  • Go Green without Sacrificing Speed. Plug in portable solar panels and get up to 500W input to charge from anywhere in as fast as 3 hours.
  • Built to Last 6x Longer. Get 10 years of daily use until hitting 80% of its original capacity. That's down to its LFP battery chemistry giving you 3000+ cycles.
  • Control from Anywhere. Use the EcoFlow app to control your DELTA 2 from anywhere using Wi-Fi. Link with Bluetooth when off-grid. Either way, you can check charging data, customize settings and adjust the charging speed with ease.
  • 5-Year. Unlock an extended 5-year customer service for worry-free experience.
*DELTA 2 Power Station and DELTA2 Extra Battery will be shipped separately.

Power went out, battery kicked in, drained out, power came back on, and the battery failed to deliver power to its AC outlets. Turns out Ecoflows randomly shut down and keep shut down the AC outlets on them. Throughout the entire process, not a single notification. Never mind having it in UPS mode or all notifications on, you'll get nothing. Ecoflows are for preppers who are standing over them to make sure they are working, they are not for automatic emergency 'as needed' backup when the grid goes out.

It does. If you remove the 45W panel from your cart, the code should work.

Yes, this. Have a delta 3 pro and found the AC outlets got disabled after last outage. Thought it was my unit but seems to be a delta thing.

Get a eco-worthy LiFePo4 battery (or other brand of choice) to expand instead. And also, opt for the Delta 2 max if you can. It has larger solar charging capacity.

...This is just slightly cheaper than other Ecoflow products have been for the past year on a /wh basis if you've been shopping around. $.33/wh is increasingly an upper reasonable limit for larger-capacity all-in systems. It's the experience curve in action, though I suspect we'll soon start hitting the limits of what's economically feasible with LFP chemistry outside of much bigger deployments.

The extra battery is also preferable if you just want to extend runtime because you're skipping the inefficiency of running a second inverter. Idle consumption is a real thing that adds up over a day+.

Are you saying you can connect a LifePo4 battery to the Delta 2?
