Head-to-head test
EcoFlow DELTA Pro Ultra + 2 Batteries vs EcoFlow TITAN 5000
Both deliver 7,200 W on 240 V, so the extra money for the DELTA Pro Ultra + 2 Batteries buys only storage, 13,414.4 Wh of it at a lower rate per watt-hour than the TITAN 5000's own pack, and that's worth paying the moment your plan is the whole house rather than a few circuits.

Spec deltas
These two have the same muscle. Both are rated for 7,200 W, and the TITAN 5000 delivers 120/240 V split-phase at 30 A through an L14-30 twist-lockB1B2, so the 240 V question that decides most TITAN comparisons doesn't decide this one.
The tank does. The bundle holds 18,432 Wh, the TITAN 5000 holds 5,017.6 Wh, and the $4,800 between $7,999 and $3,199 buys the 13,414.4 Wh in between. Divide that out and the bundle's extra storage costs less per watt-hour than the TITAN 5000's own pack. The pricier box is the discount, provided you'll use what's in it.
Whether you will comes down to how much house you're backing up. One owner found a single DELTA Pro Ultra battery ran the entire home for 4 to 5 hours at peak, and a second battery doubled itA13. A whole-house plan wants the stack. A short list of circuits through one night fits inside one TITAN pack, and for that job the TITAN 5000 is the better buy.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
Capacity
And it buys that storage at a lower rate per watt-hour than $3,199 buys the TITAN 5000's single pack. For anyone who'll eventually want the energy, the bundle is the cheaper way to own it, which is the opposite of what the sticker suggests.
DELTA Pro Ultra + 2 Batteries: 7,200 W output, two 240 V ports on its recordTITAN 5000: 7,200 W continuous, 120/240 V split-phase at 30 AB1Capacity: 18,432 Wh against 5,017.6 Wh
Why it mattersIf you expect to add TITAN packs until you reach whole-house storage, price those extra batteries against this bundle before you commit.
So on a house like that owner's, one TITAN pack is a few hours of whole-home use, not a night. The whole-home label is accurate about the inverter and optimistic about a single tank; the bundle's 18,432 Wh covers that owner's doubled runtime with room on top.
One owner: a single DELTA Pro Ultra battery ran the entire home for 4 to 5 hours at peak, and a second doubled itA13A tester refers to the DELTA Pro Ultra's own battery as 6kWhA7TITAN 5000 pack: 5,017.6 WhB6EcoFlow sells the TITAN line as whole-home backup powerB5
Why it mattersIf 'whole home' is your plan and not just the box copy, buy the storage now; if it's a few circuits, one pack will do.
solar input
With the grid down, that input is the refill. Six TITAN packs need 7.5 hours of perfect, full-rated sun to fill from empty (30,105.6 ÷ 4,000); the bundle's 18,432 Wh needs about 3.5 (18,432 ÷ 5,600). A bigger tank behind a smaller funnel is a bigger tank you rarely fill.
TITAN 5000 expands to 30,105.6 Wh across six packsB7TITAN 5000 solar: 40–450 V, 4,000 W maxB3DELTA Pro Ultra + 2 Batteries solar: 5,600 W
Why it mattersSolar-first and off-grid buyers should weigh the solar ceiling as hard as the capacity, and here it favors the bundle.
The specific dimensions that decide these two units — everything else is a tie.
Runtime: Will It Power Your Gear?
Selected because: With 7,200 W on both, stored energy is the whole difference: 15,667 usable Wh against 4,265.
After the flat 15% conversion allowance, the bundle has 15,667 Wh to spend and the TITAN 5000 has 4,265. Same inverter, same voltage, so that ratio is the entire contest: whatever you plug in, it runs more than three and a half times longer on the bundle.
The TITAN 5000 closes the gap in 5,017.6 Wh steps. Its fourth pack takes it to 20,070.4 Wh (4 × 5,017.6) and past the bundle, at which point you've bought the same storage in pieces, at a price that isn't on this page.
Growth Path
Selected because: The TITAN 5000 grows to 30,105.6 Wh, but behind a 4,000 W solar input to the bundle's 5,600 W.
solar input
On paper the TITAN 5000 has the taller ladder: six packs, 30,105.6 WhB7, against a bundle whose record says it expands without naming a ceiling. EcoFlow sells it with the 240 V Smart Home Panel 10B5, so the whole-house wiring path is there from the first pack.
The ladder's weak rung is solar, 4,000 W across a 40 to 450 V windowB3, against the bundle's 5,600 W. In a long grid-down stretch, that input decides how much of the tank you get back each day, and it doesn't grow when the tank does.
Your Life, Your Pick
Selected because: Our blackout and heavy-day loads show exactly where a single 5,017.6 Wh pack stops being enough.
Our 8-hour blackout load, 1,645 Wh, is easy for both. The TITAN 5000 finishes with 39% of its usable energy spent, the bundle with 10%, and a CPAP night is a rounding error on either. That's the TITAN 5000's best row, and a fair one for a short list of circuits.
The 4,685 Wh day is where one pack runs out: the TITAN 5000 ends 420 Wh short, and the bundle finishes with 10,982 Wh still in it. A second TITAN pack flips that row, which is the honest version of its pitch. Buy the inverter now and the storage once you know you need it.

Scoring these two at a campsite is a category error: neither travels — the DELTA Pro Ultra + 2 Batteries is 405.4 lbs and the TITAN 5000 119 lbs, and at those weights they roll off a truck bed if they go anywhere at all. The 2,100Wh here is trivial for either — it's the going that doesn't happen. If you need power away from the building, you're shopping the wrong class.

Both survive the night. The DELTA Pro Ultra + 2 Batteries finishes at 10% used with 14,022Wh left — 8.5 more nights like it. The TITAN 5000 finishes at 39% with 2,620Wh, 1.6 more nights like it. If your outages tend to run past one evening, that difference is the whole argument between them.

CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
DELTA Pro Ultra + 2 Batteries
A CPAP is about 40W for eight hours, so both of these cover the night several times over — capacity isn't the question here, and the percentages are a formality. What matters is the box next to your pillow, and the only published difference is a rating: the DELTA Pro Ultra + 2 Batteries is rated 30dB against the TITAN 5000's 39dB. Each is the maker's own published rating, and the makers do not measure the same way, some quoting a best case and some a figure under load, so neither number describes a 40W draw and the two are not really comparable. Treat them as a reason to look for hands-on reports before either one goes next to a bed, not as a difference you can count on hearing.

Conclusion
October 4, 2026
Verdict: the EcoFlow DELTA Pro Ultra + 2 Batteries
Buy the DELTA Pro Ultra + 2 Batteries if the plan is whole-house backup. The inverters match at 7,200 W and both run 240 V, so the extra $4,800 buys storage and solar: 13,414.4 Wh more battery (18,432 minus 5,017.6) and 1,600 W more solar ceiling, with the storage coming cheaper per watt-hour than the TITAN 5000's own pack. Take the TITAN 5000 at $3,199 if you're carrying a short list of circuits through a night: one pack finishes our 8-hour blackout load with plenty left, and it can grow later.
EcoFlow has not published this price yet. We priced the TITAN 5000 at $3,199 from EcoFlow's pre-launch store listing, so treat it as an estimate. We will update this comparison when the price is published.

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, DELTA Pro Ultra + 2 Batteries rates 3.8/5 (29th percentile of 29 Whole-Home / Off-Grid-class units), and TITAN 5000 rates 4.6/5 (79th 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 TITAN 5000 (119 lbs) is a two-person lift. The DELTA Pro Ultra + 2 Batteries (405.4 lbs) is spread across its boxes — no single lift, but nothing you reposition on a whim. That's a 286 lb difference, and it is paid once — getting the heavier one into position, not every time you move it.
UPS Switchover: 0ms-rated vs ≤20ms
Both list a UPS mode, at different rated speeds. The DELTA Pro Ultra + 2 Batteries is rated 0ms — a no-break design on paper, which is the maker's classification rather than a stopwatch result. The TITAN 5000 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: 10 Years vs 5
The DELTA Pro Ultra + 2 Batteries is covered for 10 years against the TITAN 5000's 5 years. The cheaper TITAN 5000 does buy more warranty per dollar (1.6 years per $1,000 against 1.3), but that is a statement about price, not about coverage — if a fault appears in year 6, only one of these is still covered. An underrated factor if you're keeping this unit for years.

Analyst note
The TITAN 5000 has no published cycle rating, so its lifetime rows use the average of the 28 LiFePO4 units EcoFlow does rate: about 3,400 cycles. That's a fair baseline for the brand but not a rating for this unit, so cost to own isn't scored on it. Judge these two on price, capacity and warranty, and read the rows marked "est." as a ballpark.

What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow DELTA Pro Ultra + 2 Batteries
Owners who bought this for whole-house backup mostly got it. One runs most of the house on a two-battery setup with no flicker when the grid drops, through the home panelA14. Another went from 4 to 5 hours of whole-home peak use on one battery to double that with a secondA13, and an owner running two of these praises the scalability and the way it heats and cools itself in temperature extremesA10. One reviewer had central air, a fridge and a well pump going at onceA9.
The friction is in the details, and much of it comes from one forum owner: a web guide instead of a manualA2, no state-of-charge graph in the appA5, and radio interference that support suggested solving with a Faraday cageA3A4. A tester measured idle drain that would empty a 6kWh battery in about 60 hoursA7, and one owner worries about a 98-degree summer garageA12. Installation is a project: one reviewer's electrician took about nine hours, drywall cutting includedA17.
“This means that without any grid or solar input, the system would fully drain its own 6kWh battery in about 60 hours. For off-grid use, this parasitic drain must be carefully factored into your energy budget.”
EcoFlow TITAN 5000
The evidence for the TITAN 5000 so far is EcoFlow's own published ratings. EcoFlow's rating label puts the pack at 5,017.6 WhB6 behind a 7,200 W, 120/240 V split-phase inverter rated at 30 AB1, with three 120 V 20 A sockets and an L14-30 twist-lockB2, solar up to 4,000 WB3, and room for six packs, 30,105.6 WhB7. Its AC IN/OUT port passes up to 7,200 W through in bypass at 120/240 VB14.
“7,200 W continuous output with 120/240 V split-phase at 30 A.”

Who Should Buy Which
Buy the DELTA Pro Ultra + 2 Batteries if you…
- →The household backing up the whole house, central air included, that would otherwise keep adding TITAN packs until it matched 18,432 Wh.
- →Off-grid and solar-first setups, where a 5,600 W solar input refills a big bank faster than 4,000 W can.
- →Buyers who'd rather own the storage today at the lower rate per watt-hour than add it a pack at a time.
Buy the TITAN 5000 if you…
- →The house that needs 240 V for a well pump on a short list of circuits, for a night, and would rather keep $4,800.
- →Someone who wants the full 7,200 W split-phase inverter now and plans to add 5,017.6 Wh packs as outages show what the house actually draws.
- →A buyer whose permit office or insurer asks for a UL 9540 certified home battery: EcoFlow lists the TITAN 5000 as certified and tested to UL 9540AB15.
If neither fits
If nothing you'd back up is on 240 V and one night is the whole job, both are more inverter than you need. Look at a 120 V home-backup unit such as the TITAN 5000 Classic instead, and keep the difference.
The Bottom Line
Buy the DELTA Pro Ultra + 2 Batteries for whole-house backup. The two inverters match at 7,200 W on 240 V, so the extra $4,800 goes entirely into storage, and it buys that storage at a better rate than the TITAN 5000 sells its own.
Take the TITAN 5000 if the job is a few circuits for a night, and add packs if the outages prove you wrong. If you already know the answer is the whole house, skip the ladder and buy the stack.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Does the EcoFlow TITAN 5000 have the same output as the DELTA Pro Ultra?
On paper, yes. Both are rated for 7,200 W continuous, and the TITAN 5000 delivers 120/240 V split-phase at 30 A through an L14-30 twist-lock. What separates them is storage: 18,432 Wh in the DELTA Pro Ultra + 2 Batteries against 5,017.6 Wh in one TITAN 5000.
Is the DELTA Pro Ultra + 2 Batteries worth the extra money over a TITAN 5000?
If you'll use the storage, yes. The $4,800 difference buys 13,414.4 Wh, and at $7,999 against $3,199 that extra storage costs less per watt-hour than the TITAN 5000's own pack. If one pack covers your outages, it's money spent on a tank you won't drain.
Can a TITAN 5000 be expanded beyond the DELTA Pro Ultra + 2 Batteries?
Yes. It takes up to six packs, 30,105.6 Wh, and passes the bundle's 18,432 Wh at four. Its solar input stays at 4,000 W however big the bank gets, against the bundle's 5,600 W.
How long will a TITAN 5000 last in a blackout?
On our 8-hour blackout load of 1,645 Wh, one TITAN 5000 finishes with 39% of its usable energy spent, enough for 1.6 more nights like it. On a 4,685 Wh day it runs 420 Wh short. A whole house is a much bigger load: one owner found a single DELTA Pro Ultra battery lasted 4 to 5 hours at peak.
What does the TITAN 5000 add beyond the spec sheet?
EcoFlow lists the TITAN 5000 as UL 9540 certified and tested to UL 9540A, and it ships with a factory pre-wired Smart Home Panel 10 that controls 10 circuits from the app. It is also modular: EcoFlow says you start at 5 kWh, add batteries up to 30 kWh with plug-in connections, and can take the system with you when you move, excluding hardwired panel work. That matters for the grow-it-later buyer this pair keeps coming back to.
