EcoFlow DELTA 3000 Gen4 vs Anker SOLIX F3000Same Battery, Same Output, 34 Lb Lighter. Why Isn't It My Pick?
The same 3,072 Wh battery and the same 3,600 W output, in a box 34 lb lighter. I'd still buy the F3000, which costs less and takes more than twice the solar, unless you'll be lifting yours by hand.

Gunner’s take
Whole-Home Backup Tester
On paper, these two are the same power station.
Anker's SOLIX F3000 and EcoFlow's DELTA 4 (3000) each hold 3,072 Wh of LiFePO4, an iron-based lithium chemistryA1. Each runs 3,600 W and surges to 7,200 WA2. The difference is the box: the DELTA 4 (3000) weighs 57.3 lb and the F3000 weighs 91.5 lb, 34 lb more for the same energy.
Anker's extra pounds come with things you'll use.
The F3000 takes 2,400 W of solar against 1,000 WA5, has a port for Anker's expansion batteries, and adds a 12 V car socket and an RV-style 30 A outlet. The DELTA 4 (3000) has no battery port at allA6. What you buy is the ceiling.
EcoFlow's answer is weight, cycles and a little polish.
It's rated for 6,000 cycles against the F3000's 4,000, switches to battery in no more than 10 ms against 20 ms, and puts 140 W through its best USB-C port against 100 W. It costs $1,699 against $1,500, and it ships in early DecemberA10. The F3000 is on sale now.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
solar input
A blackout that runs past the first night becomes a refill problem, and the wall is the one charger you don't have. At 1,000 W, a flat DELTA 4 (3000) needs more than three hours of perfect midday sun, and real sun is never perfect. The F3000's input takes more than twice that rate, if you own the panels to feed it.
DELTA 4 (3000): one solar input, 11 to 60 V, up to 1,000 WA5SOLIX F3000: 2,400 W of solar inputBoth batteries: 3,072 Wh
Why it mattersIf panels are part of your outage plan, the F3000's solar input is worth more than the DELTA 4's lighter box.
Only one of them has a way to close it. The F3000 takes an extra battery and grows past 3,072 Wh. The DELTA 4 (3000)'s only path to more energy is a second power station on the floor beside it, with its own inverter and its own price tag.
SOLIX F3000: takes Anker expansion batteriesDELTA 4 (3000): no extra-battery portA6Van Life Daily needs 4,685 Wh; both come up 2,074 Wh short
Why it mattersIf a one-night backup plan might grow into two or three days without a generator, buy the box with the port.
weight
Across a garage floor, 91.5 lb on wheels is easier than 57.3 lb in your arms. Up porch steps or into a hatchback it isn't close, and one reviewer only just got the F3000 off the groundB8. Weight is the DELTA 4's real case, and it only pays when the box travels.
DELTA 4 (3000): 57.3 lb, a handle at each end, cart sold separatelyA7SOLIX F3000: 91.5 lb on built-in wheels with an extendable handleB1B8One reviewer says the F3000 'barely passed' a manual-lift testB8
Why it mattersIf it rides in a car every month, the 34 lb is worth paying for. If it sits in one corner of the garage, it's worth nothing.
The specific dimensions that decide these two units — everything else is a tie.
Growth Path
Selected because: Both start at 3,072 Wh, and only the F3000 can add to it.
solar input
This is where the F3000 wins the page. Both start at 3,072 Wh. The F3000 has a port for Anker's expansion batteries, and the DELTA 4 (3000) has no battery port at allA6. EcoFlow kept expansion for the bigger DELTA 4 and sealed this one.
I'd only pay for the port if I expected to use it. Our 8-hour blackout uses 1,645 Wh, so a one-night plan fits in either with room to spare. Two or three days without a generator won't, and on the DELTA 4 (3000) the upgrade is a second station.
Portability & Form Factor
Selected because: 57.3 lb carried against 91.5 lb on wheels, for identical batteries.
weight
The F3000 is built to roll, and the DELTA 4 (3000) is built to carry. Reviewers say the F3000's wheels roll smoothly and its handle doesn't wiggleB1. Across a garage, 91.5 lb on wheels is the easier move.
Lifting is where the 34 lb shows. One reviewer lifted the F3000 alone for a picnic two hours awayB1. Another said it barely passedB8. The DELTA 4 (3000) has a handle at each end and is a one-person lift into a trunk, and EcoFlow sells a folding cart for it separatelyA7. I'd carry it down basement stairs myself. The F3000 I'd want help with.
What the Specs Don't Tell You
Selected because: Switchover is rated no worse than 10 ms against 20 ms, and the spec sheets leave out a couple of things worth knowing.
rated cycles
The DELTA 4 (3000) has the faster switchover rating and one missing link. EcoFlow rates it at no worse than 10 ms against the F3000's 20 ms, ceilings from the spec sheets rather than measurements. A desktop PC with a fussy power supply is where the faster rating helps. But EcoFlow's FAQ says it doesn't support HID, the USB connection that tells a computer to save its work and shut down when the battery runs lowA8.
Check the circuit before you charge it flat out. EcoFlow's X-Stream pulls up to 1,800 W from the wallA4. At 120 V that's 15 A, the full rating of an ordinary 15 A circuitA4. On a garage circuit that also feeds a freezer, I'd turn the charge rate down in the app before the breaker does it for me.
Your Life, Your Pick
Selected because: Every scenario lands identically, so the tiebreaks come from weight, ports and growth.
Every scenario comes out identical, to the watt-hour. Same battery, same derate, same result. Both finish our 1,645 Wh blackout with 966 Wh left, and a CPAP night uses 12% of either.
So the tiebreaks come from outside the battery. Weekend Camping and the tailgate go to the lighter box, and that's the DELTA 4 (3000). A laptop workday leans the same way, with 140 W of USB-C against 100 W. Van Life Daily asks for 4,685 Wh, and only the F3000 can add a battery to chase it.

Weekend Camping
Two nights off-grid with essential comfort
Either unit
A dead heat: both finish the 2,100 Wh weekend with 511 Wh to spare. The tiebreak is the trunk, and the DELTA 4 (3000) is 34 lb easier to load.

SCN-02 · 8 hours · needs 1,645Wh
8-Hour Blackout
Keep the essentials running through a night without power
Either unit
Identical batteries, identical night: both finish the 1,645 Wh blackout with 966 Wh left. The faster switchover rating, no worse than 10 ms against 20 ms, belongs to the DELTA 4 (3000).
Battery budget usedlower = more headroom
LOAD Fridge 150W×8h · Router + Modem 20W×8h · LED Lights (4 bulbs) 40W×6h · Phone Charger 15W×3h
SCN-03 · 8 hours · needs 320Wh
CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Either unit
A CPAP is about 40W for eight hours, so both of these cover the night several times over — capacity isn't the question here. What would separate them is fan noise, but SOLIX F3000 doesn't publish a figure, so there's nothing to hold it to. Buy on price, weight, and whether you can live with a fan you haven't heard.
Battery budget usedlower = more headroom
LOAD CPAP Machine 40W×8h
SCN-04 · 8 hours · needs 910Wh
Remote Workday
Full work day off-grid without power anxiety
Either unit
Both power your workstation all day without strain. At these utilization levels the real difference is USB-C for direct laptop charging — 140W on the DELTA 3000 Gen4 against 100W — which beats the inverter for convenience and wastes less energy.
Battery budget usedlower = more headroom
LOAD Laptop 60W×8h · External Monitor 30W×8h · Router + Modem 20W×8h · Phone Charger 15W×2h
SCN-05 · 4 hours · needs 670Wh
Tailgate Party
Game day power for the crew
Either unit
Both handle game day easily. Since capacity isn't the deciding factor, weight is: at 57.3 lbs the DELTA 3000 Gen4 is the one you'll be glad you brought. Fan noise under load is worth a listen too — it's audible in the lulls between songs.

Conclusion
November 4, 2026
Verdict: the SOLIX F3000
I'd buy the F3000. Both hold 3,072 Wh and both run 3,600 W with a 7,200 W surgeA2, so the battery and the inverter are a wash. The F3000 then takes 2,400 W of solar against 1,000 W, accepts Anker's expansion batteries where the DELTA 4 (3000) is sealedA6, and costs $199 less. The DELTA 4 (3000) answers with 34 lb less to lift, a 6,000-cycle rating against 4,000 and a faster switchover rating. If you carry the box by hand, that's a reason to pay more. If it lives in the garage, it isn't.

See the full weight table and data sourcing on our methodology page →Class ranking (the star rating)
Each unit's star score is a category ranking, not customer reviews — no buyer opinions feed it. We score every station on size-independent quality (value, output, portability, endurance, ports, warranty, and more), then percentile-rank it against the other units in its capacity class, so a class-leading compact unit and a class-leading whole-home unit can both earn 5★. Here, DELTA 3000 Gen4 rates 4.8/5 (86th percentile of 29 Large-class units), and SOLIX F3000 rates 4.7/5 (82nd percentile of 29 Large-class units).
How the class ranking is computed →Test Notes & Caveats
Hidden gotchas and advantages we spotted that you won't find on the product page.
34 Lb Heavier, but It Rolls
The F3000 weighs 91.5 lb to the DELTA 4 (3000)'s 57.3 lb, for the same 3,072 Wh. Its wheels and extendable handle make a garage floor easy. Porch steps and a car trunk are still a hard lift for one person.
The DELTA 4 (3000) Stops at 3,072 Wh
There's no battery port on the DELTA 4 (3000), so the battery you buy is the battery you keep. The F3000 starts at the same 3,072 Wh and takes Anker's expansion batteries. If your outage plan might grow, that port is the F3000's best argument.
UPS Switchover: ≤10ms vs ≤20ms
Both list a UPS mode, at different rated speeds. The DELTA 3000 Gen4 is rated ≤10ms — quick enough on paper that desktop PCs and routers should ride through, treating that as the rating it is. The SOLIX F3000 is rated ≤20ms — fine on paper for routers and most electronics; the fussiest PC power supplies sit right at this line. If a computer with unsaved work is the thing being protected, the stated class is worth the attention; nothing here is a lab result.
Warranty: No Difference
Both units carry the same 5-year warranty, so coverage isn't a tiebreaker here. The DELTA 3000 Gen4's figure is a maximum rather than a guarantee — it depends on registering the unit in the EcoFlow app, which adds two years to a three-year standard term.
Battery Lifespan in Real Years
The DELTA 3000 Gen4 is rated for 6,000 cycles vs 4,000. In real life: at daily use, that's 16.4 vs 11 years. At weekend use (twice a week), it's 58 vs 38 years. After hitting the cycle limit, the battery doesn't die — it drops to ~80% of original capacity, which is still very usable.
SOLIX F3000: Noise Level Not Disclosed
The DELTA 3000 Gen4 publishes its noise level (40dB); the SOLIX F3000 doesn't publish one. That isn't evidence the SOLIX F3000 is louder — it means there's no figure to hold it to, and no way to compare the two on this without hearing them. If you're buying for a bedroom, a CPAP, or an apartment, treat the DELTA 3000 Gen4's 40dB as the only published number on the table — a spec-sheet figure, not a measurement — and look for hands-on reports of the SOLIX F3000 before deciding.

Worth knowing
Support quality appears to be declining from its historically excellent level. Firmware updates have removed features without warning. Expansion ecosystem is smaller than EcoFlow's.
Analyst note
EcoFlow positions itself as a mid-to-premium brand with stronger support infrastructure, while Anker competes on value. The question is whether the EcoFlow ecosystem and support premium is worth it for your use case.
Growth path
DELTA 3000 Gen4
FIXED CAPACITYFixed at 3,072Wh — a sealed, complete system rather than a starting point. There's no expansion port, so that figure is the ceiling: check it against your longest unplugged stretch before you buy.
Accepts up to 1,000W of solar. Enough for a serious multi-panel array.
Adequate ports for most setups, but heavy users may want a power strip.
SOLIX F3000
EXPANDABLESupports Anker expansion batteries, so you can add capacity later without replacing the base unit — useful if your needs may climb past 3,072Wh.
Accepts up to 2,400W of solar. Enough for a serious multi-panel array.
Limited ports. You'll likely need a power strip or splitter.
Expansion batteries are Anker-specific. You're investing in the Anker ecosystem.
Realistic full solar rechargeat 70% of rated panel output — see methodology
Analyst note
The DELTA 3000 Gen4 is sealed at 3,072Wh, which is fine if that covers you. The SOLIX F3000 starts at 3,072Wh and can grow beyond it with Anker expansion batteries — real headroom the DELTA 3000 Gen4 doesn't have if your needs climb toward partial-home backup.
What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow DELTA 3000 Gen4
Nobody owns one yet. The DELTA 4 (3000) went on sale in the US on November 4 and ships in early DecemberA10, so this side of the page is EcoFlow's spec sheet and FAQ plus our own arithmeticA0A4A8.
I'd want a sound meter between the two at the same load. EcoFlow puts the DELTA 4 at 40 dB or less up to 1,800 WA8, and one reviewer called the F3000 practically silent under heavy loadsB5. Before anyone sleeps next to either, that's the test I'd run, and nobody has published it.
“Capacity 3,072 Wh, LFP (LiFePO4) cells. EcoFlow sells it as the DELTA 3000 Gen4; buyers and the press call the pair the DELTA 4.”
Sources

Anker SOLIX F3000
The F3000's reviews are mostly about how well it behaves. One reviewer measured 20.5 W of idle draw, under Anker's own 25 W figureB4. Another ran a Vitamix that pops 20 A breakers elsewhere without troubleB9.
The complaints are about the parts you touch. The four AC outlets sit close enough that big plugs block their neighborsB6, and the wall-charging cable uses Anker's own twist-lock plug, which barely clears the unit standing uprightB7. One reviewer found it shuts itself off running an air fryer and a microwave togetherB2, so heavy kitchen loads take turns.
“Nothing feels cheap or loose — the handle doesn't wiggle and the wheels roll smoothly; the reviewer could lift it alone without straining after taking it to a family picnic two hours away.”

“AC input 100–120 V, 15 A, 50/60 Hz; X-Stream charging up to 1,800 W from a US wall outlet. Our arithmetic: 1,800 W at 120 V is 15 A, the full rating of an ordinary 15 A circuit, so on a shared circuit you would set the charge rate lower in the EcoFlow app.”

“Nothing feels cheap or loose — the handle doesn't wiggle and the wheels roll smoothly; the reviewer could lift it alone without straining after taking it to a family picnic two hours away.”

“The battery will often turn itself off if you try to run an air fryer and a microwave at the same time, so simultaneous heavy loads need to be staggered rather than run together.”

Who Should Buy Which
Buy the DELTA 3000 Gen4 if you…
- →You'll carry it. 57.3 lb against 91.5 lb, for the same 3,072 Wh.
- →A desktop PC rides on it. Its switchover is rated no worse than 10 ms against 20 ms.
- →You charge from the wall, not the roof. X-Stream takes up to 1,800 W from an outletA4.
- →Your laptop is the big load. 140 W of USB-C against 100 W.
Buy the SOLIX F3000 if you…
- →You have panels, or plan to. 2,400 W of solar input against 1,000 W.
- →You might outgrow 3,072 Wh. It takes expansion batteries, and the DELTA 4 (3000) can'tA6.
- →You run an RV or a 12 V fridge. It has an RV-style 30 A outlet and a 12 V car socket. The DELTA 4 (3000) has neitherA3.
- →You want it before December. It's on sale now at $1,500.
If neither fits
If your backup plan includes a 240 V well pump or dryer, neither will do. Neither has a 240 V outlet, so look at a home backup system with 240 V output instead.
The Bottom Line
Same battery, same output, so I'd buy the one that does more around them: the F3000. It takes more than twice the solar, has a port to grow into, and costs $199 less.
The DELTA 4 (3000) earns the extra money only if you'll carry it. 34 lb is a real difference on stairs and into a trunk. If the box will mostly stay in one place, the wheels and the price win.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the EcoFlow DELTA 4 (3000) available in the US?
Yes. EcoFlow put it on sale at its US store on November 4, 2026 at $1,699 and says it ships in early December. The SOLIX F3000 is on sale now at $1,500.
Do the DELTA 4 (3000) and the SOLIX F3000 have the same battery?
In size, yes. Both hold 3,072 Wh of LiFePO4, and both are rated 3,600 W continuous with a 7,200 W surge. The F3000 can add expansion batteries, and the DELTA 4 (3000) can't.
Which one charges faster from solar?
The SOLIX F3000, with 2,400 W of solar input against 1,000 W. The DELTA 4 (3000) has one solar input that accepts 11 to 60 V.
Which is lighter, the DELTA 4 (3000) or the SOLIX F3000?
The DELTA 4 (3000), at 57.3 lb against 91.5 lb. The F3000 makes up for it with built-in wheels and an extendable handle.
Which battery lasts longer?
The DELTA 4 (3000) is rated for 6,000 cycles against the F3000's 4,000. At one full cycle a day, that's 16.4 years against 11, and it makes the DELTA 4 (3000) cheaper per lifetime kWh, $0.09 against $0.12. A backup unit that cycles a few times a month won't come near either rating.
