Head-to-head test
EcoFlow DELTA Pro Ultra vs Anker SOLIX S5000
The question is whether your house has a load that needs the Ultra's 7,200W inverter and no-break UPS; if it doesn't, the S5000 does the job on 4,500W for far less, and its battery is rated to outlast the Ultra's.

Spec deltas
The DELTA Pro Ultra has a 7,200W inverter and the SOLIX S5000 has a 4,500W one, and that 2,700W is most of what the extra money buys. The Ultra costs $4,199; the S5000 costs $2,500. If nothing in your house needs the bigger inverter, you are paying $1,699 for headroom you'll never touch.
The Ultra's other advantages are just as specific. Its UPS is rated 0ms, an online design that never switches over at allA3, where the S5000 is rated no worse than 10ms. Its warranty runs 10 years to the S5000's 5. And its expansion path climbs toward 90kWhA1, three times the 30,144Wh ceiling of a fully built S5000B6.
Against that, the S5000 is rated for 6,000 cycles to the Ultra's 3,500 and weighs 97 lb as one rolling box against 181.8 lb spread across the Ultra's pieces. For a house backing up the fridge, furnace blower, lights and a home office, the S5000 is the answer.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
continuous output
Central air is the one appliance in a typical house that turns this from a spec difference into a yes or no. Anker's documentation makes no central-AC claim for the S5000, while the Ultra has an owner saying it does exactly thatA4. If cooling through a summer outage is the reason you're shopping, the extra money is buying the only thing that matters to you.
DELTA Pro Ultra: 7,200W continuous, 10,800W surgeSOLIX S5000: 4,500W rated, 8,000W peakB14, 240V split-phase at 18.75AB2An owner reports the Ultra running a 3-ton central ACA4
Why it mattersHouseholds that need central AC through an outage should buy the Ultra; everyone else is buying an inverter they won't use.
rated cycles
The warranty runs the opposite way, and the two facts answer different buyers. Cycle a day off solar and the Ultra's rating runs out at about 9.6 years, right as its 10-year warranty does; the S5000 is rated for 16.4. Use either one a few times a year for storms and the cycle count never comes into play, which makes the Ultra's 10 years of cover the more useful number.
DELTA Pro Ultra: 6,144Wh x 3,500 cycles = 21,504 kWh lifetime; 9.6 years at a cycle a daySOLIX S5000: 5,024Wh x 6,000 cycles = 30,144 kWh lifetime; 16.4 years at a cycle a dayWarranty: 10 years on the Ultra, 5 on the S5000
Why it mattersDaily solar cyclers should weight the S5000's cycle rating; occasional outage users should weight the Ultra's warranty.
weight
The Ultra's weight and online UPS go together: it is built to be installed once and left running as the house's power source. The S5000 is the box you can still wheel to a different outlet. If you have a NAS, a workstation or medical equipment that must not see any gap, the Ultra's design is the safer bet; for a fridge and a furnace, 10ms is invisible.
DELTA Pro Ultra UPS: 0ms rated, online designA3SOLIX S5000 UPS: rated no worse than 10msB13Ultra: 181.8 lb across its boxes; S5000: 97 lb on wheelsB11
Why it mattersBuyers protecting gear that can't tolerate any interruption should take the Ultra; buyers protecting appliances shouldn't pay for it.
The specific dimensions that decide these two units — everything else is a tie.
What the Specs Don't Tell You
Selected because: The UPS class, the warranty term and the 84.8 lb weight gap are where the Ultra earns or loses its higher price.
rated cycles
Read the three cards here as the Ultra's whole case. A 0ms-rated online UPS, twice the warranty, and a weight that tells you this is an installation rather than an appliance. Each one is a reason to spend more only if it maps to something in your house.
The weight card cuts the other way. 181.8 lb across the Ultra's boxes is a one-time job of getting it into place; the S5000's 97 lb on a pull rod is something you can reposition on a Saturday by yourself.
Lifetime Value
Selected because: The S5000 is rated for 30,144 kWh over its life to the Ultra's 21,504, despite the smaller battery.
cost / lifetime kWh
Twenty cents a lifetime kWh for the Ultra, eight for the S5000. The bigger battery loses this one because it's rated for 3,500 cycles to 6,000, and cycles multiply.
The Ultra's 10-year warranty softens that for anyone who rarely cycles it. Cost per lifetime kWh only matters if you actually spend the lifetime.
Growth Path
Selected because: The Ultra grows toward 90kWh on 5,600W of solar; the S5000 tops out at 30,144Wh on 3,000W.
solar input
The Ultra is a platform. EcoFlow takes it toward 90kWhA1 and feeds it from up to 5,600W of solar, nearly twice the S5000's 3,000W. If your plan ends at whole-home off-grid, this is the stronger road.
The S5000 grows too, to 30,144Wh across five BP5000 packsB6. That is several days of essentials for most homes, which is where most backup plans actually stop.

Scenario verdicts
We ran the math on six real-world scenarios. Here's which unit survives your actual life.
SCN-01 · 2 nights · needs 2,100Wh
Weekend Camping
Two nights off-grid with essential comfort
SOLIX S5000
The DELTA Pro Ultra at 181.8 lbs is not a take-along — it rolls off a truck bed if it travels at all, so this scenario belongs to the SOLIX S5000 by default — and it earns it, covering the 2,100Wh with 2,170Wh to spare. Capacity was never the DELTA Pro Ultra's problem here; getting to a campsite was.

SCN-02 · 8 hours · needs 1,645Wh
8-Hour Blackout
Keep the essentials running through a night without power
Either unit
Both survive the blackout with similar margin, and both list a UPS mode — compare their stated switchover classes, and remember those are manufacturer ratings, not measurements.
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 cover the night many times over and the capacity margin is a formality. Both happen to list 30dB — two makers' own figures landing on the same number rather than a measured tie — so there is nothing in the noise column to separate them either. Buy whichever is cheaper or easier to carry.
Battery budget usedlower = more headroom
LOAD CPAP Machine 40W×8h
SCN-04 · 8 hours · needs 910Wh

SOLIX S5000
The DELTA Pro Ultra at 181.8 lbs is not a take-along — it rolls off a truck bed if it travels at all, so this scenario belongs to the SOLIX S5000 by default — and it earns it, covering the 670Wh with 3,600Wh to spare. Capacity was never the DELTA Pro Ultra's problem here; getting to a tailgate was.

DELTA Pro Ultra
The SOLIX S5000 doesn't finish — 4,270Wh usable against the 4,685Wh this needs leaves it 415Wh short, about 91% of the scenario covered (its nameplate 5,024Wh actually clears this — the flat 15% conversion allowance is what tips it under). The DELTA Pro Ultra covers it with 537Wh to spare.

Conclusion
October 9, 2026
Verdict: the Anker SOLIX S5000
Buy the SOLIX S5000 unless a specific load forces the Ultra. The S5000 costs $2,500 against the Ultra's $4,199, and for that $1,699 the Ultra gives you 2,700W more continuous output, 1,120Wh more battery, a 0ms-rated online UPSA3 and twice the warranty. Those are real, and an owner reports the Ultra running a 3-ton central ACA4. But the S5000 is rated for 6,000 cycles to the Ultra's 3,500, so it delivers more lifetime energy at well under half the cost per kWh. Pick the Ultra for central air, medical or server gear that can't take a 10ms gap, or a backup plan that has to grow toward 90kWhA1. The confidence is held at 6 because the S5000 is known only from Anker's documentationB0.

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 Pro Ultra rates 4.9/5 (95th percentile of 20 Home Backup-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 S5000 (97 lbs) is manageable solo but heavier than a large checked suitcase. The DELTA Pro Ultra (181.8 lbs) is spread across its boxes — no single lift, but nothing you reposition on a whim. That's an 85 lb difference, and it is paid once — getting the heavier one into position, not every time you move it.
UPS Switchover: 0ms-rated vs ≤10ms
Both list a UPS mode, at different rated speeds. The DELTA Pro Ultra is rated 0ms — a no-break design on paper, which is the maker's classification rather than a stopwatch result. 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. 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: 10 Years vs 5
The DELTA Pro Ultra is covered for 10 years against the SOLIX S5000's 5 years. An underrated factor if you're keeping this unit for years.
Battery Lifespan in Real Years
The SOLIX S5000 is rated for 6,000 cycles vs 3,500. In real life: at daily use, that's 16.4 vs 9.6 years. At weekend use (twice a week), it's 58 vs 34 years. After hitting the cycle limit, the battery doesn't die — it drops to ~80% of original capacity, which is still very usable.

Unique strength
The backing of a very large consumer-electronics parent, and InfiniPower, Anker's name for the design it credits for long cycle life.
Worth knowing
SOLIX support appears to have slipped from Anker's historically strong level, firmware updates have removed features without warning, and the expansion ecosystem is smaller than EcoFlow's.
Analyst note
The DELTA Pro Ultra sits at the top of EcoFlow's range, the whole-home platform the brand built its stacking batteries and inverters around. Anker's SOLIX line is smaller and its support record is trending down, which matters more on a heavy unit that ships back as hazmat freight. Register whichever you buy.

Who Should Buy Which
Buy the DELTA Pro Ultra if you…
- →You need central air through a summer outage, and an owner report of a 3-ton unit running is what you're buyingA4.
- →A NAS, workstation or medical device in the house can't take even a 10ms gap, and you want the 0ms online designA3.
- →You're building toward whole-home off-grid with up to 5,600W of solar and a bank that grows toward 90kWhA1.
- →You'll use it a few times a year and want 10 years of cover more than a long cycle rating.
Buy the SOLIX S5000 if you…
- →You're backing up the fridge, furnace blower, lights and a home office, none of which comes near 4,500W at once.
- →You'll cycle it daily off solar and want the 6,000-cycle rating working for you.
- →You want one 97 lb box on wheels you can move yourself, not an install measured in hundreds of pounds.
If neither fits
If you want the house to switch over automatically at the panel with no cords to run, look at a hardwired home battery with a transfer switch installed by an electrician instead of either of these.
The Bottom Line
The Ultra is the better machine for a house that runs central air or gear that can't blink, and its warranty is twice as long. That's a narrow list, and everything outside it goes to the S5000, which is rated to deliver more lifetime energy for far less money.
Walk through your house before you decide. If you can't name the load that needs more than 4,500W, buy the S5000 and spend the difference on panels.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the DELTA Pro Ultra worth the extra money over the Anker SOLIX S5000?
Only if you need its 7,200W inverter, its 0ms-rated UPS or its 10-year warranty. For a house that backs up essentials rather than central air, the S5000's 4,500W covers the load and its 6,000-cycle rating outlasts the Ultra's 3,500.
Can the SOLIX S5000 run central air conditioning?
Anker's documentation makes no such claim, and its 4,500W rating is 2,700W below the Ultra's. An owner reports the Ultra running a 3-ton central AC. If central air is the requirement, the Ultra is the one with evidence behind it.
Which has the better UPS, DELTA Pro Ultra or SOLIX S5000?
The Ultra. It is an online design rated 0ms, so the load never switches over. The S5000 is rated no worse than 10ms, which routers and most desktop PCs ride through but sensitive equipment may not.
Which lasts longer, the DELTA Pro Ultra or the SOLIX S5000?
The S5000's battery is rated longer, 6,000 cycles to 3,500, or 16.4 years to 9.6 at a cycle a day. The Ultra's warranty is longer, 10 years to 5. Heavy daily users should look at the cycles; occasional users at the warranty.
