Head-to-head test
Anker SOLIX F3000 vs Anker SOLIX S5000
Per watt-hour these two cost the same, so the extra money isn't a premium; it buys a bigger battery and 240V split-phase output, and whether your house has anything that runs on 240V is what decides it.

Spec deltas
The F3000 and the S5000 price out within a cent of each other per watt-hour: $.49 against $.50 on the catalogue's own figures. So the $1,000 between them isn't Anker charging extra for the bigger model. It's simply more battery, 5,024Wh to 3,072Wh, bought at the same rate.
What changes the question is the outlet panel. The F3000 has no 240V output at all; the S5000 has an L14-30R carrying 120/240V split-phase at up to 4,500WB3. Both have a TT-30R for an RV, so on 120V they're siblings. On 240V, one of them simply isn't in the conversation.
We lean S5000, at 6 out of 10. The F3000 has been through a year of reviewers' hands and came out wellA0A5; the S5000's record so far is Anker's documentation and nothing elseB0.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
continuous output
That makes the F3000 a different product, not a cheaper version of the same one. If a 240V load is on your must-run list, the $1,000 isn't an upgrade fee; it's the price of the outage plan working at all.
F3000: 240V outlets 0, TT-30R 1, 3,600W continuousS5000: L14-30R at 120/240V split-phase up to 4,500W, plus a TT-30RB3Both carry a TT-30R RV outlet, so on 120V they overlap
Why it mattersCheck your panel before you check prices: one double-pole breaker on a must-have circuit settles this page.
rated cycles
Spread the price over that throughput and the S5000 comes out at $0.08 per kWh to the F3000's $0.12. The bigger unit is a third cheaper to run per kWh, because the cycle rating, not the sticker, is where the difference lives.
F3000: 3,072Wh, 4,000 cyclesS5000: 5,024Wh, 6,000 cycles to 80%B12Catalogue cost per Wh: $.49 and $.50
Why it mattersDaily solar cyclers should read this as a straight win for the S5000; someone who uses it four times a year will never feel it.
Capacity
In a multi-day outage with the inverter on standby for the fridge's next cycle, the F3000 spends roughly a sixth of a full charge each day doing nothing. One figure is a reviewer's measurement and the other is Anker's own test, so treat the gap as directional, but it points the same way as everything else.
F3000: a reviewer measured 20.5W idle with only the inverter onA4S5000: Anker quotes 8.8W idle on 120V output, from internal testingB16Capacities 3,072Wh and 5,024Wh
Why it mattersAnyone planning to leave the inverter on through a long outage should count idle draw as a load, and it favors the S5000.
The specific dimensions that decide these two units — everything else is a tie.
Runtime: Will It Power Your Gear?
Selected because: With 1,952Wh more, the S5000 turns a one-night margin into most of a second night.
continuous output
The 8-hour blackout is where 1,952Wh becomes something you feel. The F3000 finishes with 966Wh, 59% of a second night; the S5000 finishes with 2,625Wh, about 1.6 more nights. On the weekend camping load the gap is starker: 511Wh left against 2,170Wh, which is the difference between rationing the coffee maker and not thinking about it.
One reviewer found the F3000 shuts off running an air fryer and a microwave togetherA2. The S5000's 900W of extra continuous output gives that pairing more room, but nobody has tried it on one yet, so stagger the heavy stuff on either until someone does.
Lifetime Value
Selected because: Same price per watt-hour today, but $0.08 against $0.12 per kWh over the rated life.
cost / lifetime kWh
Both carry 5 years of coverage, so the long-run difference comes from cells, not paperwork. Anker estimates a 15-year life for the S5000 at one to two cycles a dayB12; that's internal testing, and the F3000's 4,000 is a minimum on the same terms.
What's unusual here is that the bigger box doesn't charge a premium per watt-hour to start with. You're not paying for a nameplate; you're buying more of the same battery that also lasts longer.
Growth Path
Selected because: Both expand, but only the S5000's ceiling is on our record, and it reaches 30,144Wh.
solar input
Anker lists up to five BP5000 packs for the S5000, each 5,024Wh, for 30,144Wh in total, joined through a 400 V DC portB6. Our record says the F3000 expands too, but carries no ceiling for it, so we can't put a number on that side.
If you suspect today's 120V plan becomes tomorrow's whole-panel plan, the S5000 is the one that grows into it without replacing the base, and it already has the 240V outlet that plan will need.
What the Specs Don't Tell You
Selected because: The F3000 is the lighter unit with the 12V socket; the S5000 has the faster UPS rating.
rated cycles
The honest catch on our pick: the S5000 is the heavier one, 97 lb to 91.5, and it has no 12V car outlet while the F3000 doesB15. Reviewers found the F3000 a solo lift but only justA1A8, so the 5.5 lb won't change who can move these; both live on their wheels.
Going the other way, the S5000 is rated ≤10ms on UPS switchover against the F3000's ≤20ms, both ceilings rather than lab numbers. One F3000 reviewer also flagged a proprietary twist-lock charging plug that barely clears the floor when the unit stands uprightA7.

Weekend Camping
Two nights off-grid with essential comfort
SOLIX S5000
The SOLIX F3000 finishes the weekend at 80% used with 511Wh in hand — one cold night or an extra device eats into that. The SOLIX S5000 finishes at 49% with 2,170Wh, real slack for the spontaneous stuff. If you camp in variable weather, that buffer is the difference between relaxing and watching the battery app.

8-Hour Blackout
Keep the essentials running through a night without power
SOLIX S5000
Both survive the night. The SOLIX S5000 finishes at 39% used with 2,625Wh left — 1.6 more nights like it. The SOLIX F3000 finishes at 63% with 966Wh, 59% of a second night. If your outages tend to run past one evening, that difference is the whole argument between them.

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 cover the night with room to spare and capacity decides nothing. Fan noise would — 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.

Tailgate Party
Game day power for the crew
SOLIX S5000
Both handle game day; the SOLIX S5000 keeps more in reserve (16% used vs 26%). Tailgating is a light load, though, so the number you'll feel is weight: 91.5 lbs for the SOLIX F3000 against 97 lbs for the SOLIX S5000, from the trunk to the setup spot.

Neither unit
Neither unit covers this scenario's 4,685Wh: the SOLIX F3000 comes up 2,074Wh short (about 56% covered), the SOLIX S5000 415Wh (91%) (its nameplate 5,024Wh actually clears this — the flat 15% conversion allowance is what tips it under).

Conclusion
October 9, 2026
Verdict: the SOLIX S5000, on Power Score margin
Take the S5000 if you can stretch to it. It costs $2,500 against the F3000's $1,500, but the catalogue puts both at about 50 cents a watt-hour, so the $1,000 buys 1,952Wh more battery at the same rate, plus a 240V outlet the F3000 doesn't have, 6,000 rated cycles to 4,000 and a ≤10ms UPS rating to ≤20ms. Over rated life that's $0.08 per kWh against $0.12. The F3000 is the sensible buy for a 120V-only home whose outage fits inside 3,072Wh, and it's 5.5 lb lighter with a 12V socket. Confidence is 6 because the F3000 has a year of reviewer testing behind it and the S5000 has Anker's wordB0.
Today the SOLIX F3000 is $1,399.99, $100 under its typical $1,499.99. The verdict weighs typical prices, not today's. Prices checked 28 days ago.

Runtime model
Runtime = (rated capacity × 0.85 inverter efficiency) ÷ device wattage. Solar recharge estimates assume panels deliver 70% of rated output. Cold weather, battery age, and stacked loads reduce real-world results.
Power Score
Computed from 14 published spec dimensions, weighted per use-case bench. Higher is better; a unit must meet a bench's minimum threshold to be rated.
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, SOLIX F3000 rates 4.8/5 (88th percentile of 26 Large-class units), and SOLIX S5000 rates 4.6/5 (74th percentile of 20 Home Backup-class units).

Hidden gotchas and advantages we spotted that you won't find on the product page.
Weight Reality Check
Neither unit is grab-and-go. The SOLIX F3000 (91.5 lbs) is manageable solo but heavier than a large checked suitcase. The SOLIX S5000 (97 lbs) is noticeably heavier. That's a 6 lb difference.
UPS Switchover: ≤10ms vs ≤20ms
Both list a UPS mode, at different rated speeds. The SOLIX S5000 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. Worth saying because the per-dollar framing can suggest otherwise: the SOLIX F3000 works out at 3.3 years of cover per $1,000 spent against the SOLIX S5000's 2, but that spread is the price gap, not the terms.
Battery Lifespan in Real Years
The SOLIX S5000 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. One caution reading years across different sizes: a cycle is 5,024Wh on the SOLIX S5000 and 3,072Wh on the SOLIX F3000, so count lifetime energy — roughly 30,144 kWh against 12,288 kWh over the rated life. 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 SOLIX S5000 publishes its noise level (30dB); 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 SOLIX S5000's 30dB 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.

What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
Anker SOLIX F3000
The F3000 has a year of independent testing behind it, and reviewers mostly liked what they found. One measured 20.5W idle, below Anker's own 25W specA4; the same outlet called it practically silent under heavy load, a clear step up from earlier Anker unitsA5. Another ran a Vitamix that trips 20 A breakers elsewhere without a hiccupA9, and found a full AC charge took about 2 hours, or about 1 with the TT-30 cableA3.
The complaints are physical. Reviewers consistently describe the 92 lb lift as doable but hard work, with the wheels and handle doing the real jobA1A8. The four standard AC outlets sit close enough that bulky plugs block their neighborsA6, heavy loads together can trip it offA2, and one reviewer couldn't charge an EV from it because the outlet isn't groundedA10. Reddit couldn't be searched for this ledger, so owner-forum voices are missingA0.
“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 120V-only home, apartment or townhouse where nothing on the must-run list needs 240V and 3,072Wh covers a night: same battery value, $1,000 back in your pocket.
- →The RV owner plugging into a TT-30 inlet, where both units do the same job and the F3000 does it for less.
- →Anyone who wants a 12V car socket on the box for a compressor cooler or a tire inflator.
Buy the SOLIX S5000 if you…
- →The house with a 240V well pump or condenser on the outage list; the F3000 can't power it at any battery level.
- →The household that wants a second night of margin, where 2,625Wh left after the first night beats 966Wh.
- →The solar owner cycling daily, for whom 6,000 rated cycles turn the same per-watt-hour price into $0.08 per kWh against $0.12.
If neither fits
The weekend camper who has to lift it into a hatchback should skip both; at 91.5 and 97 lb these roll, they don't carry. Look at a station light enough to lift with one hand.
The Bottom Line
Buy the S5000 if you can. At the same price per watt-hour you get 1,952Wh more, half again the rated cycles and the 240V outlet the F3000 lacks, which makes it $0.08 per lifetime kWh to the F3000's $0.12.
If your house runs entirely on 120V and one night is the plan, the F3000 is a well-reviewed unit that keeps $1,000 in your account. Look at your breaker panel first; it will tell you which one to buy.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Does the Anker F3000 have 240V output?
No. Our record lists no 240V outlet on the F3000; it offers 120V outlets and a TT-30R. The S5000 has an L14-30R delivering 120/240V split-phase at up to 4,500W, so it's the one to buy for a 240V well pump or dryer circuit.
Is the S5000 worth the extra money over the F3000?
If you need 240V or more than one night of backup, yes. Both cost about 50 cents a watt-hour, so the extra money buys 1,952Wh more battery at the same rate, plus 6,000 rated cycles to 4,000. If you're 120V-only and 3,072Wh covers you, the F3000 is the smarter spend.
Which is lighter, the Anker F3000 or the S5000?
The F3000, by 5.5 lb: 91.5 lb against 97. Both ride on wheels with a pull handle, and reviewers found the F3000 a hard solo lift, so in practice neither is something you carry far.
Which uses less power on standby?
On the figures we have, the S5000. A reviewer measured the F3000 at 20.5W idle, about 492Wh a day; Anker quotes 8.8W for the S5000 on 120V, about 211Wh a day. The S5000 number is Anker's own test, so wait for an independent measurement before treating the gap as exact.
