FYI: there's a trick to get direct access to the 48V battery on Ecoflows: a 1kΩ jumper between pins 4 & 5 on the Aux battery port will enable the relays to the batteries. It's good if you want to use your own external higher power MPPT charge controller or Inverter or external 48V add-on batteries. Personally I'm hooking it up to a 25A DC-DC lab power supply... when I get time.

Also, the XT60 connector has an extra pin that tells it if the device is 8A or less (car charger) or up to 16A (solar). You either need to shell out for ecoflow branded cables or you can make XT60 adapters that jump the sense pin to + or - for whatever devices and cables you plug in.

Finally, most household 120VAC devices are limited to 12A, or 1,440W for continuous use and 15A or 1800W for short-term use. That means that this will power pretty much anything, even a level 1 electric car charger. Of course it can only run those high power devices for like an hour. Charging an electric car for an hour is good for like 4 or 5 miles. Running a heater for an hour is better than nothing in a power failure, but you're better off powering the ventilation fan and starter on a propane heater that will last for many hours or days.

The EcoFlow Delta 3 1500 is a 1536Wh portable power station that feels like a bigger, quieter Delta 2, with enough output for UPS use, routers and cameras, and even short bursts from high draw loads like air fryers or a level 1 car charger. The extra capacity is the main draw, and the unit can also support expansion batteries and app based charge limits. The main cautions are refurb uncertainty and warranty confusion, with coverage described as ranging from one year to longer EcoFlow backed terms depending on channel. It is also heavy, and a few units have shown quirks like cold weather shutdowns or app pairing issues, making it a strong capacity play if those tradeoffs are acceptable.

  • The unit can run many common 120VAC loads at about 12A continuous and around 15A short-term.

    madcow3417

  • The air-fryer style cooking load can work with brief surge near 1700W and steady 600-700W during cooking.

    OGSDER

  • The EcoFlow app can support DC port behavior for car versus solar charging through selectable settings.

    Mothma

  • The unit can reportedly run in UPS mode for networking, access points, and PoE cameras for extended outages.

    Comcastrated

  • Warranty coverage for refurbs can be unclear, with EcoFlow reportedly stating only a 1-year warranty in some cases.

    OGSDERcap1376

  • Refurb units may not include replacement batteries, which creates risk around remaining capacity and battery health.

    clouser

  • Firmware updates can require rebooting and cycling power ports, which makes updates less convenient.

    avalon

  • Some units may be unable to pair with the EcoFlow app because the app reports the version is too old to support the device.

I am struggling to find YouTube videos on this exact model. Most are the 1500 class, but I am not seeing anything on this particular version. Any input?

I need a UPS for my router, access points, and PoE cameras. Would this be reliable enough to hook up and run in UPS mode for a year or more? Also is there a software setting to limit battery charge to 80% or so to preserve battery longevity? Switchover time is not a concern for me...just want to keep things going for occasional power outages which can last up to a day.

For both of your questions, the answer is yes.

It's basically a slightly upgraded Delta 2. The only difference is the larger capacity and I've noticed the fans are not as loud as the Delta 2. Other than that, just look up specs on the Delta 2.

I have a Delta 3 Ultra and a 2x Delta 2 (and River 3). I'm trying to go through a refund/replacement for a diff model right now because my l Delta3 Ultra behaves unexpectedly with "self-powered" mode which is apparently is different than the Delta 2 Backup Reserve feature.
After some time the Delta 3 Ultra on self-powered mode constantly flips AC output between battery-solar-AC in. This does not happen on my Delta 2. As a result, it repeatedly trips my connected downstream UPS running my homelab. Again, doesn't happen when same setup running from River 3 or Delta 2. EcoFlow support is befuddled.
search Reddit if you care about TOU/solar problems with the Delta 3 series. Seems like hardware design issue.

Yes, but keep in mind that this version of the unit is really just over a year old, so even if used every day, filled and emptied to the max, it should only be down 2-3% at most. These are rated for 4,000 of those cycles before they hit 80% capacity.

Refurbs are tested and warrantied, so it's not much of a risk, but the chances of a lemon are higher than new.
I do agree, although we shouldn't forget that when we saw started to see lots of Delta 2 refurbs around a couple years ago, people's experiences with them where all over the map. Some units looked and functioned like new, while others came dirty, DOA, and beat to hell, looking like they hadn't even been tested, let alone cleaned or actually refurbished in any way. I'd trust Ecoflow over just about nay other brand in this space, and I'd guess they've only gotten better with this, but they definitely had some issues with refurbs apparently being simply reboxed and shipped out in the past.

Do they still offer 10 year warranty on refurbs?
Ecoflow offers 5 year warranty on refurb Delta and River models sold through their marketplace stores and direct. I have an email from them saying that this even applies to Temu (they have two official Temu storefronts). I also registered my 3 refurb unit and had them check. HOWEVER, they may be making eBay an unofficial channel to take advantage of the free Allstate warranty. Also, their normal refurbished units never have body damage like these are advertised to possibly have...again, they are not treating eBay like a major marketplace it would seem....I WOULD REGISTER YOUR OEM WARRANTY AND GET AN EMAIL FROM THEM saying how long it is.

Is anyone able to add these units to their ecoflow app?

I'm getting the message your app version is too old to support this device when I try to add it.

I have the newest version of the app...
