EcoFlow DELTA Pro 3 vs EcoFlow TITAN 5000
EcoFlow DELTA Pro 3 vs EcoFlow TITAN 5000: both do 120/240V, but the TITAN 5000 delivers 7,200W to a 30A L14-30 outlet against the DELTA's 4,000W, with 5,017.6Wh to 4,096Wh and 4,000W of solar to 2,600W. Take the TITAN 5000 unless everything you back up fits under 4,000W.

Spec deltas
The TITAN 5000's L14-30 outlet is marked 120/240 V at 30 AB2, and 30 A at 240 V is exactly 7,200 W, which is exactly what its inverter deliversB1. The socket and the inverter are the same size, with nothing left over. The DELTA Pro 3 also speaks 240 VA1, but its 4,000 W works out to about 16.7 A at that voltage.
That's the decision for any house running something big on 240 V. The DELTA Pro 3 can power a 240 V circuit; the TITAN 5000 can carry 80% more load on one. Add a pack 921.6 Wh larger and 4,000 W of solar input against 2,600 W, and the $400 premium is buying a lot of hardware.
The catch sits on the input side. The TITAN's AC inlet is a single 100–120 V, 15 A input, and EcoFlow's label limits draw above 12 A to under three hoursB8, while the DELTA Pro 3 stacks inputs to as much as 7,000 WA3. The TITAN 5000 is a solar-first machine. If you refill from panels, or you simply need more watts in the outage itself, it's the one to buy.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
continuous output
Whatever you hang on a 240 V transfer circuit, the TITAN carries 80% more of it before the inverter becomes the limit. On the afternoon an outage runs long and every heavy load wants to run at once, that headroom decides what stays on.
TITAN 5000: 7,200 W continuous, 120/240 V split-phase at 30 AB1TITAN 5000: one L14-30 twist-lock marked 120V/240V 30AB2DELTA Pro 3: 4,000 W continuous, dual-voltage 120/240 VA1
Why it mattersAnyone backing up more than one big 240 V load should treat the DELTA Pro 3's 4,000 W as the ceiling it is and step up.
solar input
A full 30,105.6 Wh TITAN bank refills in about 7.5 hours of rated sun; a full 48 kWh DELTA Pro 3 bank needs about 18.5 hours through its 2,600 W input. A bigger tank only helps if you can fill it, and in a multi-day outage the TITAN's roof keeps pace with its batteries.

Why it mattersIf your outage plan is panels rather than a generator, the TITAN 5000's growth path is the one that closes the loop.
The TITAN 5000 refills fastest from the roof. From a generator or the returning grid it takes what one 15 A circuit gives, while the DELTA Pro 3's multi-charge path can be fed up to 7,000 W, which reviewers turn into about 50 minutes to 80%A3.

Why it mattersHouseholds that plan to refill from a generator between short, repeated outages should set that inlet against the TITAN's extra watts before they buy.
The specific dimensions that decide these two units — everything else is a tie.
Runtime: Will It Power Your Gear?
Selected because: The 3,200 W output gap and the 921.6 Wh pack gap point the same way, and this is where they meet.
continuous output
The pack gap is the smaller story. A battery 921.6 Wh larger buys the TITAN 5000 over a fifth more of every night, 4,265 Wh usable against 3,482 Wh after the same 85% conversion allowance. The number that changes what you can plug in is the inverter: 7,200 W against 4,000 W. Watt-hours you can't deliver fast enough never reach the load.
At 240 V that turns into 30 A against roughly 16.7 A. The DELTA Pro 3 runs out of inverter a little past halfway up a 30 A circuit; the TITAN fills it.
Growth Path
Selected because: Both expand, but the TITAN 5000's 4,000 W solar input refills its full bank in far fewer hours of sun than the DELTA Pro 3's 2,600 W can manage for its larger ceiling.
solar input
Here the DELTA Pro 3 has the bigger number and the TITAN 5000 has the better plan. The DELTA expands to 48 kWhA1; the TITAN to 30,105.6 Wh, which is its base pack plus five EF-TT-E5-G1 extra batteries of 5,017.6 Wh eachB7.
Divide each by its own solar input and the order flips. Expansion fed through 2,600 W is a bigger tank behind the same narrow filler neck, and the TITAN's 4,000 W is the wider neck.
Your Life, Your Pick
Selected because: The everyday profiles show how little of either inverter a normal night uses, which is why the 240 V question carries this page.
Six everyday profiles, and the busiest peaks at 400 W, under 6% of the TITAN 5000's 7,200 W. These rows were never going to settle a 240 V question. They read capacity, and the TITAN's bigger pack shows up as a smaller percentage in each one: the 8-hour blackout takes 39% of it against 47% of the DELTA Pro 3.
The row worth a second look is Van Life Daily. Its 4,685 Wh leaves the TITAN 5000 420 Wh short and the DELTA Pro 3 1,203 Wh short, and the TITAN's miss is about six minutes of its rated solar input.

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 3 is 112.4 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.

CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
DELTA Pro 3
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 3 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 TITAN 5000, on Power Score margin
Buy the TITAN 5000. Both units run 120/240 V, but the TITAN 5000 delivers 7,200 W continuous at 30 A split-phaseB1 against the DELTA Pro 3's 4,000 W, which is about 16.7 A at 240 V. For $400 more it also adds 921.6 Wh of pack and 1,400 W of solar input. The DELTA Pro 3 keeps two honest edges: its multi-charge path stacks inputs to as much as 7,000 WA3 where the TITAN's AC inlet stops at 15 A on 120 VB8, and it expands to a higher ceiling. Choose the DELTA only if everything you back up fits inside 4,000 W.

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 3 rates 4.0/5 (42nd percentile of 20 Home Backup-class units), and TITAN 5000 rates 4.6/5 (79th percentile of 20 Home Backup-class units).

Weight Reality Check
Neither unit is grab-and-go. The DELTA Pro 3 (112.4 lbs) is a two-person lift. The TITAN 5000 (119 lbs) is firmly a two-person lift. It goes where you put it and stays there. That's a 7 lb difference.
UPS Switchover: ≤10ms vs ≤20ms
Both list a UPS mode, at different rated speeds. The DELTA Pro 3 is rated ≤10ms — quick enough on paper that desktop PCs and routers should ride through, treating that as the rating it is. 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: No Difference
Both units carry the same 5-year warranty, so coverage isn't a tiebreaker here.

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.

Who Should Buy Which
Buy the DELTA Pro 3 if you…
- →Everything you back up, the 240 V side included, runs comfortably inside 4,000 W, and you'd rather keep $400 than buy headroom you won't touch.
- →Refill speed is your priority: reviewers time the DELTA Pro 3 at about 50 minutes to 80% on up to 7,000 W of multi-charge inputA3, where the TITAN's AC inlet stops at 15 A on 120 VB8.
- →You want to plug an RV's 30 A cord straight in: our record lists an RV 30 A outlet on the DELTA Pro 3 and none on the TITAN 5000.
Buy the TITAN 5000 if you…
- →You have more than one big load on double-pole breakers, say a well pump and an air handler, and want the headroom to run them together: 7,200 W is a full 30 A at 240 V.
- →You're sizing a solar array for multi-day outages and want an input that keeps pace with a growing bank: 4,000 W against 2,600 W.
- →You're wiring it to EcoFlow's 240 V Smart Home Panel 10, which is how EcoFlow sells the line for whole-home backupB5.
- →You're on time-of-use rates and want solar to run the house first and the battery to cover peak hours; EcoFlow's X-Fusion 2.0 is built for thatB23, while its OASIS 3.0 scheduling is a subscription feature in the appB17.
If neither fits
If every circuit you care about runs on 120 V, neither is the efficient buy: the TITAN 5000 Classic shares this pack and chassisB6B13 without the split-phase side. And if your heaviest outage night is a fridge and a CPAP, both of these are utility-room installations doing a portable's job; a far smaller station will cover it.
The Bottom Line
Buy the TITAN 5000. Its 7,200 W fills a 30 A split-phase circuit to the brim where the DELTA Pro 3's 4,000 W gives out a little past halfway, and the $400 premium also brings a bigger pack and a roof input that can actually refill an expanded bank.
Keep the DELTA Pro 3 in mind only if your loads live under 4,000 W, or refill speed from stacked inputs matters more to you than outage watts. Otherwise the bigger inverter is the whole reason to shop at this size, and the TITAN 5000 is the one that has it.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Does the TITAN 5000 have more power than the DELTA Pro 3?
Yes, 80% more continuous output: 7,200 W against 4,000 W. At 240 V that's 30 A from the TITAN's L14-30 outlet against about 16.7 A from the DELTA. The pack is larger too, 5,017.6 Wh against 4,096 Wh.
Can the DELTA Pro 3 run 240 V like the TITAN 5000?
Yes. It's dual-voltage 120/240 V, so it can feed a 240 V circuit. What it can't do is match the TITAN 5000's watts on that circuit: 4,000 W in total, against 7,200 W.
Which recharges faster, the DELTA Pro 3 or the TITAN 5000?
With every input in use, the DELTA Pro 3 has the higher ceiling: up to 7,000 W of multi-charge input, which reviewers time at about 50 minutes to 80%. The TITAN 5000's AC inlet is 100–120 V at 15 A, about 1,800 W, with draw above 12 A limited to under three hours. On solar alone the TITAN leads, 4,000 W against 2,600 W.
How much can you expand the TITAN 5000?
To 30,105.6 Wh: the base unit plus five EF-TT-E5-G1 extra batteries, each a 5,017.6 Wh pack. The DELTA Pro 3's ceiling is higher at 48 kWh, though its 2,600 W solar input would need about 18.5 hours of rated sun to fill that from empty.
Is the TITAN 5000 worth the extra money over the DELTA Pro 3?
For a home with heavy 240 V loads, yes: $400 buys 3,200 W more inverter, 921.6 Wh more battery and 1,400 W more solar input. If your loads fit inside 4,000 W, the extra watts sit idle and the DELTA Pro 3 is the sensible spend.
What does the TITAN 5000 add beyond the spec sheet?
EcoFlow lists it as UL 9540 certified and tested to UL 9540A, and sells it with a factory pre-wired Smart Home Panel 10 that gives app control of 10 circuits. X-Fusion 2.0 has solar power the home first and the battery cover peak-rate hours, and AC coupling lets compatible existing rooftop solar keep working with that panel and a CT sensor. OASIS 3.0 forecasts solar up to 3 days ahead and charges off-peak, but EcoFlow marks it a subscription feature in its app. These are EcoFlow's published claims for the TITAN 5000.
