EcoFlow DELTA Pro Ultra + 1 Battery vs EcoFlow TITAN 5000

Both put out 7,200 W with 240 V output, so the gap between them buys nothing but battery and solar input, and battery is the one part the TITAN 5000 lets you add later.

On continuous output these two are a dead heat: 7,200 W each, and both can feed a 240 V circuitB1. That's the part of a home battery you can't change after you buy it. What differs is the battery behind it, 12,288 Wh in the DELTA Pro Ultra + 1 Battery against 5,017.6 Wh in the TITAN 5000B6.

So the $2,800 gap buys stored energy and solar input, and nothing on the output side. The DELTA Pro Ultra is the cheaper of the two per watt-hour, which is its strongest card: if you already know your house wants 12,288 Wh, it gets you there in one order.

Most outages never ask for it. The engine's 8-hour blackout uses 39% of the TITAN 5000, and its 4,000 W solar input can refill the whole pack in a little over an hour of full-rated sun (5,017.6 ÷ 4,000)B3. Buy the TITAN 5000 and let the first long outage tell you whether to add a pack.

02

What the Numbers Reveal

Each conclusion stated first — the numbers behind it on one line, the full analysis below.

F1

And stored energy is exactly what the TITAN 5000 can add later, one 5,017.6 Wh pack at a timeB7. A bigger inverter you can't bolt on. So the real choice is between paying for 12,288 Wh today and paying for 5,017.6 Wh today with the option on more.

Both: 7,200W continuous outputTITAN 5000: 120/240V split-phase at 30AB1TITAN 5000 extra battery adds 5,017.6Wh per pack, up to 30,105.6WhB7

Why it mattersIf you can't say how long your worst outage will run, buy the TITAN 5000 and let the outage answer before you buy more battery.

F2

That's the clean path into a 240 V transfer setup, and EcoFlow sells the TITAN 5000 bundled with its 240 V Smart Home Panel 10 for exactly thatB5. On continuous output the DELTA Pro Ultra's premium buys nothing extra: 7,200 W is 7,200 W.

TITAN 5000 L14-30 twist-lock outlet marked 120V/240V 30AB2TITAN 5000 continuous output: 7,200WB1TITAN 5000 AC IN/OUT bypass: up to 7,200W at 120/240V, 30AB14

Why it mattersIf your plan is a 240 V transfer panel fed by one cable, the TITAN 5000 runs it at full rating for less money.

F3

solar input

With the grid down for days, that combination is what carries a house through a bad week: 5.3 nights of reserve after the first, and the bigger solar intake to top it back up. That's the DELTA Pro Ultra's buyer, somewhere a storm can mean days before the lines come back.

DELTA Pro Ultra + 1 Battery: 12,288Wh, 5,600W solar inputTITAN 5000: 5,017.6Wh, 4,000W solar inputB38-Hour Blackout: DELTA Pro Ultra has 5.3 more nights in reserve, TITAN 5000 has 1.6

Why it mattersIf your outages are long and your sun unreliable, the DELTA Pro Ultra's extra battery pays its way; if they end by morning, it's battery you'll pay for and rarely touch.

The specific dimensions that decide these two units — everything else is a tie.

Runtime: Will It Power Your Gear?

Selected because: Output is a tie at 7,200W, so stored energy is the only spec the price gap actually buys.

Everything the gap buys comes down to about 7,270 Wh (12,288 minus 5,017.6), and the DELTA Pro Ultra sells it as the cheaper of the two per watt-hour. That's the best case for it on this page: if your house genuinely needs that much stored energy, owning it in one order is the efficient way to get there.

The catch is the word genuinely. An overnight outage at the engine's blackout load leaves the TITAN 5000 with more than half its usable energy untouched, so for that house the extra battery pays for a third and fourth night that never arrive. Size for the outages your area actually gets, not the worst one you can imagine.

Growth Path

Selected because: The TITAN 5000 adds battery in 5,017.6Wh packs, which turns this into a buy-it-now-or-later question.

solar input

EcoFlow's extra battery for the TITAN matches the base pack exactly, 5,017.6 Wh apiece, up to six packs and 30,105.6 WhB7. One extra pack makes 10,035.2 Wh, still short of the DELTA Pro Ultra + 1 Battery; two make 15,052.8 Wh, past it. The pack's price isn't on this page, so if you already know you'll end up at that size, price the full TITAN bundle against the DELTA Pro Ultra before assuming the smaller start is cheaper overall.

The DELTA Pro Ultra expands too, and its 5,600 W solar input is the bigger pipe for feeding a bigger bank. For the buyer who starts small and stays small, though, the TITAN's path is the one that lets the outages decide.

Your Life, Your Pick

Selected because: The blackout and heavy-day rows show how much of the DELTA Pro Ultra's extra battery a real outage uses.

The overnight blackout and the workday are comfortable on either unit; the difference is in what's left over, not whether you make it. The heavy 4,685 Wh day is the honest test of the smaller pack: the TITAN 5000 comes up 420 Wh short once the engine's 15% allowance comes off, about 91% of the way there, while the DELTA Pro Ultra finishes with 5,760 Wh in hand. If back-to-back heavy days with no sun are your plan, that's the row that should move you.

Scenario math and per-appliance runtimes, modeled from the spec record.

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

Neither unit

Scoring these two at a campsite is a category error: neither travels — the DELTA Pro Ultra + 1 Battery is 293.6 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.

8-Hour Blackout

Keep the essentials running through a night without power

DELTA Pro Ultra + 1 Battery

Both survive the night. The DELTA Pro Ultra + 1 Battery finishes at 16% used with 8,800Wh left — 5.3 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 + 1 Battery

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 + 1 Battery 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.

A full day of mobile living — the ultimate endurance test

DELTA Pro Ultra + 1 Battery

The TITAN 5000 doesn't finish — 4,265Wh usable against the 4,685Wh this needs leaves it 420Wh short, about 91% of the scenario covered (its nameplate 5,018Wh actually clears this — the flat 15% conversion allowance is what tips it under).

Conclusion

October 4, 2026

Verdict: the TITAN 5000

Buy the TITAN 5000. It matches the DELTA Pro Ultra + 1 Battery's 7,200 W of continuous output with 120/240 V split-phase of its ownB1, for $2,800 less, and it covers the engine's 8-hour blackout at 39% used. When an outage proves you need more, it grows in 5,017.6 Wh steps to 30,105.6 WhB7. Switch to the DELTA Pro Ultra + 1 Battery if you're planning for multi-day, grid-down outages from the start: it's the cheaper of the two per watt-hour, and it takes 1,600 W more solar input (5,600 W against 4,000 W).

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.

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 + 1 Battery rates 3.7/5 (25th percentile of 29 Whole-Home / Off-Grid-class units), and TITAN 5000 rates 4.6/5 (79th percentile of 20 Home Backup-class units).

Test Notes & Caveats

Hidden gotchas and advantages we spotted that you won't find on the product page.

[CAUTION]

Weight Reality Check

Neither unit is grab-and-go. The TITAN 5000 (119 lbs) is a two-person lift. The DELTA Pro Ultra + 1 Battery (293.6 lbs) is spread across its boxes — no single lift, but nothing you reposition on a whim. That's a 175 lb difference, and it is paid once — getting the heavier one into position, not every time you move it.

[NOTE]

UPS Switchover: 0ms-rated vs ≤20ms

Both list a UPS mode, at different rated speeds. The DELTA Pro Ultra + 1 Battery 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.

[NOTE]

Warranty: 10 Years vs 5

The DELTA Pro Ultra + 1 Battery is covered for 10 years against the TITAN 5000's 5 years. 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 + 1 Battery

The DELTA Pro Ultra's field record here rests mostly on one owner's detailed DIY Solar Forum thread from early 2024; our research turned up nothing about the + 1 Battery pairing in particular and nothing long-termA0. That owner came away "kind of meh" and unlikely to expand itA4. The headline complaint is radio interference: frequencies like 146.520 MHz were disturbed even with the inverter off, and the interference stopped only when the unit was shut downA6.

Metering is the other worry. The same owner watched a reported "90%" collapse to "8%" after a few days of overnight use and rechargingA9, and found no state-of-charge history in the appA8. Support's answer to the interference was a faraday cageA7, and the documentation is a web guide the owner called superficialA5. One owner, one thread, early firmware: things to test in your own first week, not a verdict.

Who Should Buy Which

Buy the DELTA Pro Ultra + 1 Battery if you…

  • →The house where a storm can mean days without power, with panels on the roof or planned: 12,288 Wh in reserve and 5,600 W of solar input to keep refilling it.
  • →The buyer who already knows they want 12,288 Wh or more and would rather pay the lower per-watt-hour price once than build up to it pack by pack.
  • →Anyone expecting heavy loads through a full day without sun: the heavy-day profile leaves the DELTA Pro Ultra with 5,760 Wh to spare.

Buy the TITAN 5000 if you…

  • →The house with one or two 240 V loads, a well pump or a dryer, and outages that are over by morning: the same 7,200 W and 240 V for $2,800 less.
  • →The buyer wiring a 240 V transfer panel who wants one 30 A twist-lock cable carrying the whole outputB2.
  • →Anyone who would rather buy 5,017.6 Wh now and add packs after the first bad storm than guess at it todayB7.
  • →A time-of-use-rate home that wants the battery to cover peak hours on its own: EcoFlow lists X-Fusion 2.0 for the TITAN 5000B23, and OASIS 3.0 adds off-peak charging as a subscription feature in the EcoFlow appB17.

If neither fits

If nothing you need is on a 240 V circuit, both are charging you for a 240 V inverter you'll never use, and a 120 V unit such as the TITAN 5000 Classic fits better. And if you want an all-electric house carried through a week-long outage without rationing anything, that's a standby generator's job, not a battery's.

The Bottom Line

Buy the TITAN 5000. On output it matches the DELTA Pro Ultra + 1 Battery watt for watt, and the thing you're not buying is battery, which it lets you add a pack at a time once an outage shows you need itB7. The DELTA Pro Ultra earns its $2,800 premium in one house only: the one that already knows its outages last days.

Frequently Asked Questions

Answers drawn from the spec record and cited owner research.

Do the EcoFlow TITAN 5000 and DELTA Pro Ultra have the same output?

On continuous output, yes: 7,200 W each, and both have 240 V output. The TITAN 5000's L14-30 outlet is rated 30 A at 240 V, which is the full 7,200 W on one plug. Where they differ is battery and solar input, not output.

How many TITAN 5000 batteries equal a DELTA Pro Ultra + 1 Battery?

Three packs. Each TITAN pack is 5,017.6 Wh, so the base unit plus two extra batteries makes 15,052.8 Wh, past the DELTA Pro Ultra + 1 Battery's 12,288 Wh, while base plus one makes 10,035.2 Wh, short of it. The extra battery's price isn't on this page, so compare complete bundles before deciding.

Is the DELTA Pro Ultra + 1 Battery better value than the TITAN 5000?

Per watt-hour, yes: it's the cheaper of the two by that measure. Per watt of output, the TITAN 5000 matches its 7,200 W for $2,800 less. Value follows use, and if you won't drain past 5,017.6 Wh in your typical outage, the extra battery is money parked in a utility room.

How fast does the TITAN 5000 recharge from solar?

Its solar input takes 40–450 V at up to 4,000 W, so from empty the 5,017.6 Wh pack needs a little over an hour of full-rated sun (5,017.6 ÷ 4,000). The DELTA Pro Ultra + 1 Battery accepts up to 5,600 W but has 12,288 Wh to fill, a little over two hours at full rating. Real panels rarely hold their rating all day, so treat both as best cases.

What does the TITAN 5000 add beyond the spec sheet?

Beyond the matching 7,200 W, EcoFlow lists X-Fusion 2.0: solar powers the home first, the battery covers peak-rate hours, and working with the grid through the main panel it can power loads beyond the backed-up circuits. It is UL 9540 certified and tested to UL 9540A and comes with a pre-wired Smart Home Panel 10 that gives app control of 10 circuits. EcoFlow's OASIS 3.0 forecasts solar 3 days ahead and charges off-peak, but the store marks it a subscription feature in the EcoFlow app.
