Head-to-head test
Anker SOLIX F2000 vs Anker SOLIX S2000
Anker SOLIX F2000 vs Anker SOLIX S2000: Anker has stopped selling the F2000, so only the S2000 is buyable, and it earns the pick anyway with 10,000 rated cycles against 3,000 at half the weight. The F2000's one real edge was 2,400W continuous against 1,500W, so take that requirement to the C2000 Gen 2 only if you need it.

Spec deltas
Anker no longer sells the SOLIX F2000, the unit also sold as the PowerHouse 767. That is the first thing to know and it changes the question you came here with: you were choosing between two power stations and only one of them can be ordered. The named replacement in Anker's range is the SOLIX C2000 Gen 2. The SOLIX S2000 is the live unit on this page, and it is the recommendation.
The good news is that this is not a consolation prize. Take the retirement away and the S2000 still wins most of what these two argue about, starting with a pack rated for 10,000 cycles against the F2000's 3,000 at almost identical capacity, 2,009.6Wh against 2,048Wh. It also weighs 35.7 lbs where the F2000 weighs 67.2, and it is rated at no worse than 10ms on UPS switchover where the F2000 is rated at no worse than 20ms.
The one place the F2000 was clearly stronger is how much it would run simultaneously: 2,400W continuous against 1,500W. Its 1,000W solar input against 400W is the other real gap. Neither of those is a reason to chase discontinued stock, but both are reasons to be honest about what a 1,500W ceiling means before you check out, and if it is too low for your load the successor is where to take that question rather than this page.
What the Numbers Reveal
Each conclusion stated first β the numbers behind it on one line, the full analysis below.
continuous output
And the surge difference barely exists: 3,000W against 2,800W is 200W of ceiling, about 7% (200 divided by 2,800). Nothing on this page should be decided on that. What actually separates the two inverters is 900W of continuous output (2,400 minus 1,500), and that is a question of simultaneity rather than startup. A load drawing the S2000's full 1,500W is its entire budget with nothing left over; the F2000 had 900W of room above the same load.
SOLIX S2000: 1,500W continuous, 3,000W surgeSOLIX F2000: 2,400W continuous, 2,800W surgehighest startup draw in any of this page's six load profiles is 400W, in the tailgate profile, and both units start it
Why it mattersIf your worry was whether it will start a fridge compressor, stop worrying and decide on weight and cycle life instead. If your worry is running two heavy things at the same time, neither of these is your unit.
rated cycles
Both give you the same single night. Only one gives you three decades of them. Cycled daily, the F2000 pack reaches its rating inside a decade while the S2000 is still in its first third, and both carry the same 5-year warranty, so that difference plays out entirely on your side of the paperwork.
SOLIX S2000: 10,000 rated cycles at 2,009.6Wh, for 20,096 kWh of rated lifetime throughputSOLIX F2000: 3,000 rated cycles at 2,048Wh, for 6,144 kWhat one cycle a day that works out to 27.4 years against 8.2
Why it mattersAnyone cycling a unit every day, in a van, a cabin, or a daily solar shuffle, should treat cycle life as the headline spec here and capacity as the tie it actually is.
weight
Which one wins depends entirely on whether your route is flat. Garage to patio on concrete, the F2000 was genuinely the better tool for the job. Over a tailgate, up basement stairs, or into a van, 31.5 lbs of difference beats any handle, and you can hug an awkward 35.7 lb box in a way you cannot hug a 67.2 lb one.
SOLIX S2000 weighs 35.7 lbs; SOLIX F2000 weighs 67.2 lbs, a 31.5 lb differenceindependent reviews repeatedly credit the F2000's 4.72-inch wheels and retractable EasyTow handle as the reason owners picked it over similar-spec rivalsA1two outlets independently flagged the S2000's missing one-hand carry handle as awkward for one-person transportB7B8
Why it mattersIf the unit never leaves level ground, the F2000's rolling design was the nicer experience and the S2000 will mildly annoy you every time you lift it. If it ever meets stairs, that annoyance is the better problem.
solar input
So the S2000's refill is quick wherever there is a grid and slow wherever there isn't. Plugged into a wall it is back to full inside two hoursB5, which covers the way most people will actually use it. On panels in a multi-day outage or a boondocking week, 400W means you are harvesting all day to bank one cycle, and an overcast day costs you the cycle.
SOLIX F2000 accepts 1,000W of solar input; SOLIX S2000 accepts 400Wboth packs are about 2 kWh: 2,048Wh and 2,009.6Whreviewers measured the S2000 recharging from a standard household circuit to 80% in about 1.2 hours and full in about 1.7B5
Why it mattersIf sun is your only refill, this is the one spec on which the S2000 is the weaker unit, and it is a reason to ask about the SOLIX C2000 Gen 2 rather than to settle for 400W.
The specific dimensions that decide these two units β everything else is a tie.
Lifetime Value
Selected because: Near-identical capacity, 2,009.6Wh against 2,048Wh, and then 10,000 rated cycles against 3,000. This is where the two packs stop resembling each other.
Two packs within 38.4Wh of each other, and one of them is rated to deliver more than three times as much energy before it fades. Cycled once a day the S2000's rating covers 27.4 years against the F2000's 8.2; at weekend use it is 96 years against 29, which is really just a long way of saying that normal use does not reach the end of a 10,000-cycle pack. Hitting the rating is not a death either. The cells drop to about 80% of original capacity and keep working.
That is the gap that would have decided this page even if both units were still for sale, and it is worth understanding what it is not. It is not a warranty difference, because both units carry the same 5 years. It is a difference in how much of the pack's life you use up every time you run it down, and it accrues silently to whoever still has the thing in year nine.
What the Specs Don't Tell You
Selected because: The output specs read backwards at a glance: the 1,500W unit has the higher peak at 3,000W, and the 2,400W unit has less room above its own rating.
rated cycles
Read the two inverters quickly and you will get them backwards. The 1,500W unit is the one with the higher peak, 3,000W against 2,800W, because Anker built it with twice the headroom over its own continuous rating while the F2000 has only about 1.2x. Neither fact should sell you anything: 200W of extra ceiling is about 7% and the heaviest startup draw in any load profile on this page is 400W, which both units clear without noticing. Surge is settled here, in both directions.
The specs in this section that do move a decision are quieter ones. The S2000 is rated at no worse than 10ms on UPS switchover against the F2000's no worse than 20ms, and if the thing you are protecting is a desktop with unsaved work, the stated class is worth the attention even though neither figure is a measurement. The noise column is an asymmetry rather than a gap: the S2000 publishes 30dB on its spec sheet and the F2000 publishes nothing at all, which is not evidence that the F2000 is louder. It just means there is no number to hold it to.
Portability & Form Factor
Selected because: 67.2 lbs that rolls against 35.7 lbs that has to be lifted, so weight and ease of moving point in opposite directions here.
weight
Half the weight, and still the more awkward carry. The S2000's 35.7 lbs is the sort of load one person manages, but reviewers at two outlets independently complained about the lack of a proper one-hand handleB7B8, while the F2000's owners kept naming its 4.72-inch wheels and retractable handle as the reason they bought itA1. Rolling 67.2 lbs across a campsite is easier than lifting 35.7 lbs into a truck bed.
Which means the honest answer depends on your terrain rather than the number. Flat ground favours wheels, every time. The moment a step, a tailgate, or a van's side door enters the route, the 31.5 lb difference reasserts itself and the argument is over.
Growth Path
Selected because: One of these takes expansion batteries and one is sealed at 2,010Wh, and the retirement decides which of those facts you can still act on.
solar input
The F2000 has the one card the S2000 cannot answer: an expansion port that takes Anker batteries, with a ceiling well past the 2,010Wh the S2000 is sealed at. That is a real limitation on the S2000 and not the kind we usually wave away, because the expanded ceiling genuinely would have beaten it rather than merely matching it.
It is also a growth path you can no longer enter. A discontinued base unit is a poor foundation for a system you intend to grow, and the reader who needs headroom past 2,010Wh should not solve it by finding leftover retailer stock of the F2000. Take the requirement to the SOLIX C2000 Gen 2 instead. The S2000 is the right buy for the person whose number is 2,010Wh and stays there, and the wrong one for anyone who already suspects it won't.

Neither unit
Neither unit covers this scenario's 2,100Wh: the SOLIX F2000 comes up 359Wh short (about 83% covered), the SOLIX S2000 392Wh (81%). Either gets you most of the way, so this is a scenario you plan around rather than one you should rule them out for.

8-Hour Blackout
Keep the essentials running through a night without power
Either unit
Both finish the night, and neither finishes it comfortably. The profile wants 1,645Wh and leaves the F2000 with 96Wh of usable energy in reserve and the S2000 with 63Wh, which is a pass with the lights already dimming rather than a cushion you can plan around. Since capacity does not separate them, the rated switchover class does: no worse than 10ms on the S2000 against no worse than 20ms on the F2000, and those are manufacturer ratings rather than stopwatch results. Assume a real outage runs longer than eight hours and plan the recharge, not the runtime.

SCN-03 Β· 8 hours Β· needs 320Wh
CPAP Overnight
Sleep therapy without interruption β the #1 medical use case
Either unit
A CPAP draws about 40W, so the night costs roughly 320Wh and both units treat it as a rounding error, 18% and 19% of the pack respectively. Capacity is not the spec for the person lying 18 inches from the machine at 3 a.m. The fan is, and here the two units are not comparable rather than close: the S2000 publishes 30dB on its spec sheet and the F2000 publishes no figure at all. That is not evidence the F2000 is louder, only that there is nothing to hold it to, which is a different kind of risk to accept.

Either unit
Both handle game day without breathing hard, and this is the profile with the heaviest startup draw on the page at 400W, which both clear so far out that surge ratings tell you nothing useful about a tailgate. Weight tells you everything: 35.7 lbs against 67.2, and the S2000 is the one you will be glad you carried from the lot. Worth a listen either way, since a fan under load is audible in the lulls between songs.

Conclusion
September 19, 2026
Verdict: the SOLIX S2000, on Power Score margin
Buy the SOLIX S2000 at $700. Anker has discontinued the F2000, so there is one candidate here you can actually order, and it happens to be the one that would have won a live matchup on most axes anyway: 10,000 rated cycles against 3,000 from a pack within 2% of the same size, 35.7 lbs against 67.2, a faster rated UPS class at no worse than 10ms, and a marginally higher surge ceiling at 3,000W. Two things genuinely went the other way and you should decide against them rather than around them. The F2000 ran 2,400W continuous where the S2000 stops at 1,500W, and it took 1,000W of solar against the S2000's 400W. If either of those is your requirement, the answer is not to hunt retailer stock of a discontinued unit; it is to take the requirement to the SOLIX C2000 Gen 2 and check it there.

Each unit's star score is a category ranking, not customer reviews β 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 5β . Here, SOLIX F2000 rates 3.7/5 (24th percentile of 26 Large-class units), and SOLIX S2000 rates 5.0/5 (99th percentile of 26 Large-class units).
How the class ranking is computed βTest Notes & Caveats
Hidden gotchas and advantages we spotted that you won't find on the product page.
SOLIX F2000: 67.2 lbs Is a Commitment
At 67.2 lbs, this is manageable but not fun to move. That's heavier than a large checked suitcase. How much it costs you depends on whether it rolls β wheels and a telescoping handle change the job completely at this weight, and our spec record doesn't track them, so look at the product photos before you plan on carrying it from the car.
S2000: Sealed at 2,010Wh, And the Escape Hatch Is Closed
The S2000 is fixed at 2,010Wh with no expansion port, and this one is a real limitation rather than a technicality, because the F2000's expansion batteries would have taken it genuinely past that ceiling rather than merely matching it. The catch is that the F2000 is no longer sold, so the growth path this comparison points at is not one you can enter. Check 2,010Wh against your longest unplugged stretch before you order, and if the number is already tight, ask about the SOLIX C2000 Gen 2 instead of planning to expand a unit you cannot buy.
Surge: The Higher Ceiling Belongs to the Smaller Inverter
The S2000 peaks at 3,000W over a 1,500W continuous rating, so 2x headroom, against the F2000's 2,800W over 2,400W, or about 1.2x. Both the ratio and the absolute ceiling go to the S2000, which is the opposite of what the continuous ratings suggest. Take the advantage, but do not pay for it: 200W of ceiling is about 7%, and the heaviest startup draw in any load profile on this page is 400W. What the F2000's inverter actually bought was 900W more continuous output, which is a question of how many things run at once rather than whether any single one starts.
UPS Switchover: β€10ms vs β€20ms
Both list a UPS mode, at different rated speeds. The SOLIX S2000 is rated β€10ms β quick enough on paper that desktop PCs and routers should ride through, treating that as the rating it is. The SOLIX F2000 is rated β€20ms β 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.
Battery Lifespan in Real Years
The SOLIX S2000 is rated for 10,000 cycles vs 3,000. In real life: at daily use, that's 27.4 vs 8.2 years. At weekend use (twice a week), it's 96 vs 29 years. After hitting the cycle limit, the battery doesn't die β it drops to ~80% of original capacity, which is still very usable.
SOLIX F2000: Noise Level Not Disclosed
The SOLIX S2000 publishes its noise level (30dB); the SOLIX F2000 doesn't publish one. That isn't evidence the SOLIX F2000 is louder β 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 S2000's 30dB as the only published number on the table β a spec-sheet figure, not a measurement β and look for hands-on reports of the SOLIX F2000 before deciding.

Analyst note
The SOLIX F2000 is no longer sold, so there is no price to work its cost per kWh from, and this comparison doesn't quote one. On what you can actually buy today, the SOLIX S2000 works out at $0.03/kWh over its rated life. If you already own the SOLIX F2000, the hardware comparison still holds: over its rated life the SOLIX F2000 delivers about 6,144 kWh and the SOLIX S2000 about 20,096 kWh.

Analyst note
Growth only counts if you can still buy in, and the SOLIX F2000 is no longer sold (Anker points owners to the SOLIX C2000 Gen 2). That leaves the SOLIX S2000: it is sealed at 2,010Wh, so buy the size that covers you now. The SOLIX F2000's expandability still matters if you already own one, but it isn't a reason to pick it over the SOLIX S2000.
What Owners Report
Patterns from published owner reports and long-term reviews β every claim cited to its source below.
Anker SOLIX F2000
The F2000's reputation was built on the fact that it rolls. Independent reviews keep landing on the 4.72-inch wheels and the retractable EasyTow handle as the specific reason owners chose it over similar-spec competitorsA1, and for the loads RVers actually run, the fridge, the CPAP, lights, fans, internet and a TV, reviewers describe it as quiet, capable and fast to set upA3. That last point is the only real handle anyone has on its fan noise, since Anker publishes no figure. App monitoring over Wi-Fi and Bluetooth draws consistent praise, and a meaningful number of owners reported Anker resolving problems with firmware updates or replacement unitsA2. The pack's LFP chemistry and 3,000-plus cycle rating are the other recurring positivesA4.
Worth knowing where all that comes from: our coverage of this unit leans on review sites and Anker's own materials rather than large independent owner forums, so the marketing-adjacent claims deserve some caution. The wheels-and-handle praise is the part that repeats across genuinely independent reviewsA0.
βIt's big and full of heavy batteries, but the durable 4.72-inch wheels and retractable EasyTow handle make it surprisingly easy to lug around β most positive reviews cite the wheels and telescoping handle as a top reason owners chose it over similar-spec competitors.β

Anker SOLIX S2000
Everything known about the S2000 is short-term. It launched in June 2026, so there are no forum threads and no six-months-later longevity reports, but two outlets did run real hands-on tests rather than rewriting the press kitB0. Both found the same thing about noise, which is the finding that matters most for a unit you might sleep beside: the fans spin up only under heavy load or the fastest charging mode, and at idle it is effectively silentB1B2. Both measured standby draw in single digits, about 2W with everything disabled and about 6W with the AC ports on but unusedB3B4. Both watched connected office equipment ride through a simulated grid cut without a flickerB9B10, and the app came in for praise as the more polished one in the categoryB11.
The complaints are specific and small. Two reviewers independently called one-person transport awkward for 35.7 lbs because there is no dedicated one-hand handleB7B8. One noticed a faint warm-electronics smell within a few feet of the unit during the first hours of sustained load in a small closed office, which faded within a day with no safety concernB6. Against that, one reviewer ran a fridge and assorted kitchen gadgets for more than 60 hours on a single chargeB12, and the measured wall recharge matched Anker's own claimB5. Early, but early and clean.

Claims are weighted by how specific they are, whether the commenter owns the unit, and how many readers agreed. Comments that mention a product under a rival's review count for more, because the commenter had no reason to be there.

Who Should Buy Which
Buy the SOLIX F2000 if youβ¦
- βYou already own one. Nothing about the retirement changes what it does: 2,048Wh, 2,400W continuous, a 1,000W solar input and an expansion port that still takes Anker batteries. Plan its replacement around the 3,000-cycle rating rather than around a failure date, because at weekend use that rating is 29 years away.
- βYou need 2,400W of continuous output and you are shopping now. The F2000 is the shape of the answer rather than the answer, since it cannot be ordered. Take the 2,400W requirement to the SOLIX C2000 Gen 2 and confirm it there before you look at anything else.
- βYou refill from panels rather than wall power. The F2000's 1,000W solar input against the S2000's 400W is the one spec gap on this page that a workaround does not close, and it is worth naming as the thing to check on the successor.
Buy the SOLIX S2000 if youβ¦
- βYou run it down and refill it nearly every day. A van, an off-grid cabin, a daily solar shuffle: at one cycle a day the 10,000-cycle rating covers 27.4 years against 8.2, and that is the whole ballgame for this buyer.
- βYou are 18 inches from it all night with a CPAP on. The night costs about 320Wh against 1,708Wh of usable capacity, so 19% of the pack, and capacity decides nothing. What decides it is the fan, and the S2000 is the only unit here with a published figure and two independent reports of a silent idleB1B2.
- βYou want a blackout box for a desk. It is rated at no worse than 10ms on switchover, reviewers saw office kit ride through the transition untroubledB9B10, and it carries the 8-hour blackout profile's 1,645Wh with 63Wh of usable energy left, which is a pass rather than a cushion.
- βYou will be carrying it. 35.7 lbs is the whole argument, awkward handle and all, and it is half of what the F2000 asks of your back.
If neither fits
Anyone whose real load is bigger than one of these. This page's weekend camping profile wants 2,100Wh and the S2000 covers about 81% of it, coming up 392Wh short; van life wants 4,685Wh and it covers 36%, short by 2,977Wh. The same is true of anyone who needs two heavy appliances running at once, since 1,500W is the S2000's entire continuous budget. If that is you, you want a bigger pack or a genuinely expandable system rather than a 2 kWh box, and the honest move is to size the system first and shop second.
The Bottom Line
Buy the SOLIX S2000. The F2000 has left Anker's range, which settles the page before the specs get a vote, and the specs then agree anyway: the same size pack rated to deliver more than three times the energy over its life, at half the weight, with a faster rated switchover class. Cycled daily that is the difference between a unit you replace inside a decade and one you will probably hand down.
Two caveats to carry to the checkout, both named above rather than discovered later. The S2000 stops at 1,500W continuous, so simultaneous heavy loads are its wall, and it takes only 400W of solar, so a panel-only refill is a full day's work rather than a morning's. Neither is a reason to go looking for discontinued stock. If either one is your requirement, ask about the SOLIX C2000 Gen 2. If neither is, order the S2000 and stop reading.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the Anker SOLIX F2000 discontinued?
Yes. Anker no longer sells the SOLIX F2000, which was also sold as the PowerHouse 767, and its named replacement in Anker's range is the SOLIX C2000 Gen 2. There is no price or buy link for it on this page for that reason. Its specs are still accurate and still worth comparing if you own one or turn up leftover retailer stock, but it cannot be the recommendation.
Which one actually surges higher, the F2000 or the S2000?
The S2000, at 3,000W peak against the F2000's 2,800W, despite having the lower continuous rating of 1,500W against 2,400W. That is because Anker gave it 2x headroom over its own continuous output where the F2000 has about 1.2x. In practice the 200W difference in ceiling is too small to decide anything, and both units start every load profile on this page, the heaviest of which peaks at 400W.
Does the S2000's 1,500W output limit what I can run?
It limits how much you can run at the same time, not whether a given motor will start. One appliance drawing 1,500W uses the entire continuous budget, where the F2000 had 900W of room above the same load. Add up the nameplate wattage of everything you expect to have plugged in simultaneously and check it against 1,500W before you buy, because that number is the S2000's one hard wall.
How long will the Anker SOLIX S2000 last?
It is rated for at least 10,000 cycles, which works out to 27.4 years at a cycle a day or about 96 years at twice a week. Reaching that rating does not kill the battery either; capacity drops to roughly 80% of original and the unit keeps working. The warranty is 5 years, the same term the F2000 carried.
Can I add more capacity to the SOLIX S2000 later?
No. It is sealed at 2,009.6Wh with no expansion port, so what you buy is the ceiling. The F2000 did take Anker expansion batteries, but since it has left the range that is not an available path any more, so if you expect to outgrow about 2 kWh you should look at the SOLIX C2000 Gen 2 rather than plan an expansion around a discontinued base unit.
