Head-to-head test
EcoFlow TITAN 5000 vs BLUETTI EP900 + 2×B500
The TITAN 5000 matches the BLUETTI's 240 V to within 400 W, so the BLUETTI's premium buys energy and a bigger solar inlet; one extra pack covers the first, and only someone mounting more than 4,000 W of panels collects on the second.

Spec deltas
Both of these put 240 V on your house circuits, and their inverters sit 400 W apart: 7,200 W of split-phase output on the TITAN 5000A1, 7,600 W on the BLUETTI EP900 bundle. The well pump, the dryer and the central-air condenser all live on 240 V, and both deliver it. That leaves energy, solar and form to justify the BLUETTI's $10,298 against the TITAN's $3,199.
Energy is the BLUETTI's clearest lead, 9,920 Wh to 5,017.6, and also its shallowest. EcoFlow's extra battery matches the TITAN's pack, so one of them takes the TITAN 5000 to 10,035.2 Wh, past the BLUETTI as it shipsA7.
Solar is the lead that survives. The BLUETTI accepts 9,000 W of panels and the TITAN 5000 tops out at 4,000 WA3. With 4,000 W of panels or fewer, that extra inlet sits idle; above it, it's the best reason to pay. For a 240 V home buying backup rather than building a solar plant, the TITAN 5000 is the pick.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
continuous output
On power delivery these are close to twins, one through a twist-lock plug and one through the panel. Nobody should pay the BLUETTI's premium for 400 W, so if it's worth paying, the reason is somewhere else on the page.
TITAN 5000: 7,200 W continuous, 120/240 V split-phase at 30 AA1TITAN 5000 outlets: three 120 V 20 A sockets and one L14-30 marked 120V/240V 30AA2EP900 + 2×B500: 7,600 W continuous, 240 V through its hardwired panel connection
Why it mattersAnyone leaning BLUETTI because it sounds like the bigger inverter should take output off the scale and decide on energy and solar.
Capacity
That reserve is what the BLUETTI is really selling a 240 V household, and one EcoFlow battery matches it: the TITAN 5000 plus a single pack holds 10,035.2 Wh (5,017.6 × 2) against 9,920.
TITAN 5000 pack: 5,017.6 Wh; each extra battery matches it, to 30,105.6 WhA7EP900 + 2×B500: 9,920 Wh8-Hour Blackout, 1,645 Wh: the TITAN 5000 keeps 1.6 more nights in reserve, the BLUETTI 4.1
Why it mattersIf multi-night outages are why you're shopping, compare the BLUETTI with the TITAN 5000 plus one pack, not the bare TITAN.
solar input
That's exactly where the TITAN's own growth path strains: six packs at 4,000 W need about seven and a half hours of full-rated input to refill (30,105.6 ÷ 4,000 = 7.5). A big bank under a big roof is the BLUETTI's home ground.
TITAN 5000 solar: 40–450 V, 4,000 W maxA3EP900 + 2×B500 solar: 9,000 W maxTITAN 5000 ceiling: six packs, 30,105.6 WhA7
Why it mattersIf your array plan stops at 4,000 W, ignore the solar column; if it doesn't, it's the strongest case on this page for the BLUETTI.
The specific dimensions that decide these two units — everything else is a tie.
Growth Path
Selected because: The BLUETTI's energy lead is one EcoFlow extra battery deep, while its 9,000 W solar inlet against the TITAN's 4,000 W is the advantage that survives expansion.
solar input
Treat this as two separate races. In energy, the BLUETTI leads by a battery, and the TITAN 5000 closes that with one EF-TT-E5-G1 before running on to six packs and 30,105.6 WhA7. The BLUETTI's ceiling is higher again, about 39.6 kWh across eight B500 modulesB2, though either limit is a great deal of house.
In solar, the gap stays open. The TITAN 5000's 40–450 V input tops out at 4,000 WA3; the BLUETTI takes 9,000 W. As a bank grows, the BLUETTI's inlet keeps refills short while the TITAN's stretch out. That is the BLUETTI's most durable advantage here, and it only pays if the panels exist.
Your Life, Your Pick
Selected because: With both delivering 240 V, the scenario rows are where the energy gap stops being abstract.
On the same 1,645 Wh blackout night, the TITAN 5000 ends at 39% used and the BLUETTI at 20%. For one night, both are comfortable. For a storm that keeps the grid down all week, the TITAN's answer is a second pack or a solar array, and it should be planned before the storm rather than during it.
The CPAP and Remote Workday rows are a wash: a 320 Wh CPAP night is 8% of the TITAN 5000 and 4% of the BLUETTI. Neither row should move a 240 V buyer one way or the other.
Runtime: Will It Power Your Gear?
Selected because: Matched on voltage, the two separate on usable energy: about 4,265 Wh on the TITAN 5000 after the 85% derate, about 8,432 Wh on the BLUETTI.
continuous output
Put a 240 V load on each at full output and the energy gap gets vivid. The TITAN's usable 4,265 Wh lasts about half an hour at 7,200 W (4,265 ÷ 7,200 = 0.6); the BLUETTI's 8,432 Wh lasts about an hour at 7,600 W (8,432 ÷ 7,600 = 1.1).
Nobody runs either flat out for long. A well pump runs in bursts and a dryer finishes its load. But it's a reminder that 240 V capability and 240 V endurance are separate purchases, and the TITAN's endurance comes in 5,017.6 Wh stepsA7.
Brand Trust
Selected because: Each is a whole-house system, so who answers when one faults matters for years, and the two brands' support records are not alike.
EcoFlow's support is US-based by phone, email and chat, with a polarized record, and where you buy matters: Costco or Amazon gives a stronger return net. BLUETTI's support is email-heavy, slowed by China-timezone delays and the most inconsistent in the category, with direct purchases faring better.
So the buying advice runs in opposite directions: the TITAN from a big retailer, the BLUETTI from BLUETTI. On a system that feeds your panel, the channel is part of the purchase.

Weekend Camping
Two nights off-grid with essential comfort
Neither unit
Scoring these two at a campsite is a category error: the TITAN 5000 at 119 lbs is not a take-along — it rolls off a truck bed if it travels at all, and the EP900 + 2×B500 is installed at the electrical panel — it backs up the building and doesn't leave it. 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.

EP900 + 2×B500
Both survive the night. The EP900 + 2×B500 finishes at 20% used with 6,787Wh left — 4.1 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
TITAN 5000
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 TITAN 5000 is rated 39dB against the EP900 + 2×B500's 50dB. 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.

Neither gives you a powered van: the EP900 + 2×B500 has the energy but is wired to the building, and the TITAN 5000 covers about 91% of the 4,685Wh. One can't go; the other can't finish.

Conclusion
October 4, 2026
Verdict: the EcoFlow TITAN 5000
Buy the TITAN 5000. It delivers 120/240 V split-phase at 7,200 WA1, and its L14-30 outlet is rated to carry that whole output through one plugA2, which puts it level with the BLUETTI on the question most whole-home buyers start with. What the BLUETTI's $7,099 premium adds is nearly twice the energy as shipped and a 9,000 W solar inlet against 4,000 WA3. One EF-TT-E5-G1 extra battery erases the firstA7. The second pays only if your array will be larger than 4,000 W. Choose the BLUETTI if it will, or if you want one finished, panel-mounted system with a ceiling near 39.6 kWhB2.

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, TITAN 5000 rates 4.6/5 (79th percentile of 20 Home Backup-class units), and EP900 + 2×B500 rates 3.7/5 (21st percentile of 29 Whole-Home / Off-Grid-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 EP900 + 2×B500 (343 lbs) is a wall-installed system — its weight matters to the installer on day one, then never again.
EP900 + 2×B500: 50dB Published
50dB is about as loud as moderate rainfall. The TITAN 5000 is rated 39dB — lower, but published by a different maker measuring its own way, so the two figures are not a like-for-like gap. For most people, fan noise around 45dB and up is where sleep starts to suffer.
UPS Switchover: ≤10ms vs ≤20ms
Both list a UPS mode, at different rated speeds. The EP900 + 2×B500 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: 10 Years vs 5
The EP900 + 2×B500 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), 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.
Full record above — the Test Desk pick is the TITAN 5000.

What happens after you buy — true cost of ownership, brand trust, and growth potential.
Lifetime value
Service lifeyears at one full cycle per day
Lifetime energy delivered
Cost per delivered kWh
│ warranty ends · Reaching the cycle rating means ~80% capacity remains — degraded, not dead. est. = no published cycle rating; the brand’s average is used instead.
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.
Brand trust
EcoFlow
Ecosystem
Largest in portable power — 12-15 models across DELTA Pro, DELTA 3, and RIVER 3 series, plus solar panels and smart home panels
Support
US-based phone/email/chat support (1-800-368-8604). Experiences are polarized — many report hassle-free prepaid-label replacements, but others report long waits and refurbished units sent for new claims. Pro tip: buying from Costco or Amazon gives you a stronger return safety net.
Community
Largest community in the space — Reddit r/Ecoflow_community (~31K members), multiple Facebook groups, and an official community forum
App experience
Rated 4.6/5 iOS (~8,400 ratings) · 4.2/5 Android (~17,000 ratings)
Unique strength
Fastest-charging technology (X-Stream), deepest product ecosystem, and most active innovation cadence. At the top of the range sit two whole-home paths: the TITAN line, one 5 kWh unit that grows to 30 kWh, and the DELTA Pro Ultra platform, which stacks batteries and inverters further — flagship paths, not line-wide features.
Worth knowing
Tested subscription paywalls for advanced app features in early 2025 before community backlash paused the plan. No parts or service offered out of warranty.
BLUETTI
Ecosystem
One of the broadest lineups — 15-20+ models from budget (AC2A) to flagship portable (Apex 300, 2764.8Wh). Includes specialized products: vehicle solar hubs, sodium-ion cold-weather units, and balcony storage systems.
Support
The most inconsistent support in the space. Heavily email-based with China timezone delays. Some users get smooth, efficient service; others report weeks of troubleshooting runarounds, being offered discounts on new units instead of repairs, and confusing third-party purchase claim processes. Buying direct from Bluetti's website tends to produce better support outcomes.
Community
Active and growing — Reddit r/bluetti has a dedicated community. Second-largest after EcoFlow in engagement.
App experience
Rated 4.5/5 iOS and Android — tied for best app experience in the category. V3.0 UI redesign was well-received.
Unique strength
Among the best capacity-to-price ratios available — several Elite and Apex units are the lowest $/Wh in the catalog. Widest product diversity including industry-firsts like sodium-ion cold-weather units and dual solar+alternator vehicle hubs. LFP across the rest of the range, though rated cycle life spans 2,500 (EB3A) to 6,000, and it varies WITHIN the Elite range rather than tracking it — the Elite 300 and Elite 200 V2 are rated 6,000 while the Elite 30 V2, Elite 10 Mini, Elite 320 and Elite 400 are rated 3,000+ and the Elite 100 V2 4,000+, so check the specific model. Dual-voltage (120V/240V) in flagships.
Worth knowing
Customer support inconsistency is the #1 risk factor. Older/discontinued units may become unrepairable — no spare parts policy for some models. Some reports of erratic communication from support agents.
Analyst note
EcoFlow positions itself as a mid-to-premium brand with stronger support infrastructure, while BLUETTI competes on value. The question is whether the EcoFlow ecosystem and support premium is worth it for your use case.

Analyst note
Both expand, but the EP900 + 2×B500's higher solar ceiling (9,000W vs 4,000W) gives it the stronger off-grid growth path — more panels can feed a bigger bank as it grows.
What Owners Report

EcoFlow TITAN 5000
Everything on file for the TITAN 5000 is EcoFlow's own rating label and store page. It establishes 7,200 W of 120/240 V split-phase output at 30 AA1, an L14-30 beside three 20 A socketsA2, a 4,000 W solar input across 40–450 VA3, and the shared 5,017.6 Wh packA6 growing to 30,105.6 WhA7. The pack voltage points to LFP cells by our arithmetic, not by any EcoFlow statementA12. It is documentation, not field reportingA0.

BLUETTI EP900 + 2×B500
BLUETTI's ledger is mostly the platform pitch from BLUETTI's site and guide pagesB1B2: a whole-home inverter meant to run a washer, dryer, heater and refrigeratorB1, and B500 modules that stack to about 39.6 kWhB2. The owner material is two single entries, so neither makes a pattern. One owner found the grid-to-battery handover unnoticeable during outagesB3; one running it with solar describes something close to off-grid livingB4.
“A whole-home system: one EP900 inverter provides up to 9,000W (18,000W with two units), enough to run a washer, dryer, heater, and refrigerator.”

Who Should Buy Which
Buy the TITAN 5000 if you…
- →The house with one 240 V load that must run, a well pump or an electric dryer, and a budget that stops well short of the BLUETTI: the TITAN 5000's L14-30 puts 240 V on itA2.
- →The buyer who wants to start at 5,017.6 Wh and grow toward 30,105.6 Wh a pack at a timeA7, wiring the house through EcoFlow's 240 V Smart Home Panel 10 bundleA5.
- →Anyone whose solar plans stop at 4,000 W of panels: the TITAN's inlet takes all of itA3, so the BLUETTI's bigger one would sit idle.
- →A home that already has rooftop solar and wants to keep it: EcoFlow says the TITAN 5000 AC couples with compatible panels, with the Smart Home Panel 10 and a CT sensorA19.
Buy the EP900 + 2×B500 if you…
- →The off-grid property with room for well over 4,000 W of panels and a bank that keeps growing: 9,000 W of solar input and a ceiling near 39.6 kWhB2.
- →The household that wants 9,920 Wh on the first day as one finished system, mounted at the panel by an electrician with no sockets on the box, and is content to pay for that convenience.
If neither fits
If the plan is keeping a fridge cold and phones charged through a single evening, a 240 V system of either brand is the wrong category. A mid-size portable station does that job, plugs straight into the fridge, and costs a small fraction of either.
The Bottom Line
The TITAN 5000 matches the BLUETTI where a 240 V home starts, on voltage and to within 400 W on output, for far less money. The BLUETTI's energy lead is one extra pack deep. Its solar lead is real and matters only to someone mounting more than 4,000 W of panels.
If that's you, the BLUETTI is a fair price for a system built to grow. If it isn't, the TITAN 5000 runs the same 240 V circuits, and you keep the difference.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Does the EcoFlow TITAN 5000 have 240V?
Yes. It delivers 120/240 V split-phase at 30 A and 7,200 W continuous, through an L14-30 twist-lock outlet alongside three 120 V 20 A sockets. The BLUETTI EP900 delivers 240 V too, but through its hardwired panel connection rather than an outlet on the box.
TITAN 5000 or EP900: which runs more of my house at once?
The BLUETTI, by 400 W: 7,600 W continuous against the TITAN 5000's 7,200 W. That's a thin margin for the price difference. Both put 240 V on the circuits that need it, so the real decision is stored energy and solar input.
Can I add batteries to the TITAN 5000 to match the EP900 + 2×B500?
Yes, and it takes one. Each EcoFlow EF-TT-E5-G1 extra battery matches the TITAN's 5,017.6 Wh, so a single pack brings it to 10,035.2 Wh against the BLUETTI's 9,920 Wh, with room for six packs and 30,105.6 Wh in all. The BLUETTI goes further, to about 39.6 kWh with eight B500 modules.
Can the TITAN 5000 live in an unheated garage?
Mind the winter. EcoFlow's label rates it to charge between 32 °F and 113 °F and to discharge down to 14 °F, so below freezing it can still run the house but won't take a charge until it warms. The label also places it in a utility space, outside bedrooms and living areas.
What does the TITAN 5000 add beyond the spec sheet?
EcoFlow lists the TITAN 5000 as UL 9540 certified and tested to UL 9540A. The TITAN 5000 ships with a factory pre-wired Smart Home Panel 10 that controls 10 circuits from the app. The TITAN 5000 can AC couple with compatible existing rooftop solar, which needs the Smart Home Panel 10 and a CT sensor. The TITAN 5000 starts at 5 kWh, grows to 30 kWh by plugging in batteries, and EcoFlow says it moves with you.
