Head-to-head test
EcoFlow TITAN 5000 vs BLUETTI EP900 + 3×B500
With 240 V on both sides, the BLUETTI's lead is a 9,000 W inverter against 7,200 W and nearly three times the energy, and the TITAN 5000 can buy back the energy pack by pack but never the watts.

Spec deltas
Both of these make 240 V, which retires the question that decides most whole-home comparisons. The TITAN 5000 puts split-phase at 30 A on an L14-30 twist-lock beside three 20 A household socketsA2, driven by a 7,200 W inverterA1. The BLUETTI EP900 with three B500 batteries feeds 240 V straight into the panel from 9,000 W. One costs $3,199, the other $13,798.
Ignore price and the BLUETTI leads on every axis this page can measure: nearly three times the stored energy (14,880 Wh against 5,017.6 Wh), 1,800 W more continuous output, and more than double the solar intake (9,000 W against 4,000 WA3). Put price back and the biggest of those leads turns out to be something the TITAN sells you later, one 5,017.6 Wh pack at a timeA7.
Not every lead, though, and that's the hinge of this page. Energy is the part you can add; inverter watts and solar intake are the parts you can't. If 7,200 W running at once covers your house, the TITAN 5000 is the buy and the $10,599 difference stays in your account.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
continuous output
So the question that settles this isn't how big a battery you need; it's how much has to run at the same moment. On the 240 V side, 7,200 W is 30 A of draw (7,200 ÷ 240) and the EP900's 9,000 W is 37.5 A (9,000 ÷ 240). A house whose simultaneous load stays inside the TITAN's 30 A gets nothing from the BLUETTI's extra inverter except the invoice.
TITAN 5000: 7,200 W continuous, 120/240 V split-phase at 30 AA1EP900 + 3×B500: 9,000 W continuous, 240 V hardwiredTITAN 5000: expandable to 30,105.6 Wh in matching 5,017.6 Wh packsA7
Why it mattersAdd up what must run at once, not over a day: under 7,200 W, the TITAN's smaller pack is a problem you can buy your way out of later; over it, only the BLUETTI answers.
solar input
That advantage reverses the moment you expand to match. EcoFlow's label lists one 4,000 W solar input on the base unitA3, so a three-pack TITAN holding the BLUETTI's energy takes nearly four hours of perfect sun to fill, more than twice the BLUETTI's time. Buy packs to match the EP900's battery and you've matched its battery, not its roof.
TITAN 5000 solar input: 40–450 V, 4,000 WA3EP900 + 3×B500 solar input: 9,000 WStorage: 5,017.6 Wh against 14,880 Wh
Why it mattersIf solar, not the grid's return, is how you plan to get through a long outage, the BLUETTI's 9,000 W input is the one lead a bigger TITAN can't purchase.
That's a real planning difference for a house with no basement or utility room, but the outdoor route carries its own doubt: another poster wouldn't count on an outdoor install through real heat or a run of cold, sunless daysB6. Neither unit lets you skip the question of where it lives; the TITAN just answers 'indoors' from the start.
TITAN 5000: indoor siting in a utility space, outside bedrooms and living areasA10TITAN 5000: charges only between 0 °C and 45 °CA11One forum poster notes BLUETTI sells an enclosure so the EP900 can be kept outdoorsB5
Why it mattersIf your only free space is outside, price the BLUETTI's enclosure; if you have a utility room, the TITAN's indoor rule costs you nothing.
The specific dimensions that decide these two units — everything else is a tie.
Growth Path
Selected because: Two extra TITAN packs pass the bundle's 14,880 Wh, but the 4,000 W solar input doesn't grow with them.
solar input
Here the BLUETTI's capacity lead stops being permanent. The TITAN's frame takes six matching packs, 30,105.6 Wh in allA7, so two extra batteries put it past the bundle's 14,880 Wh, and EcoFlow already sells the extra battery in TITAN bundlesA5. The BLUETTI expands too, with more BLUETTI batteries; it simply starts where the TITAN needs two purchases to reach.
What doesn't grow is intake. The engine hands this section to the BLUETTI for its 9,000 W solar ceiling against the TITAN's 4,000 W, and that's the correct reading: every pack you add lengthens the TITAN's solar day without widening the door the sun comes through.
Runtime: Will It Power Your Gear?
Selected because: Nearly three times the stored energy is the BLUETTI's largest lead, and the one the TITAN can buy back.
continuous output
Run anything on both and the BLUETTI keeps going about three times as long: 12,648 Wh usable against 4,265 Wh, after the engine's flat 85% derate. That's the lead you can buy back. Add two TITAN packs and the TITAN edges ahead on stored energy; whether that route costs less than the bundle comes down to EcoFlow's price for the packs, which no runtime chart can show you.
The lead you can't buy back is width. At 7,200 W the TITAN covers a lot of house at once on split-phase, but if your must-run loads add up past that, the BLUETTI's 9,000 W is the only one of these two with room for them.
Your Life, Your Pick
Selected because: The blackout row turns the energy gap into nights, and none of these profiles comes near either inverter's limit.
The blackout night is where the energy gap becomes something you'd feel. Both finish the 1,645 Wh profile; the TITAN is left with 2,620 Wh, the BLUETTI with 11,003 Wh. In nights, that's 1.6 more against 6.7 more, a weekend's margin against a week's.
Look at the peaks, though: no profile here asks for more than 400 W, so neither the TITAN's 7,200 W nor the BLUETTI's 9,000 W is anywhere near tested. These rows measure the tank, not the engine, and the tank is the half of this comparison the TITAN can enlarge.
Brand Trust
Selected because: Whole-home backup stays in the house for years, so each maker's support record is part of the purchase.
The BLUETTI's weak flank is the one prospective buyers name before they've spent anything: supportB1B2. The corroborating complaints are general BLUETTI reviews that may concern other modelsB11B12, so read them as a brand pattern rather than a verdict on the EP900. BLUETTI support tends to go better when you buy direct, which on a $13,798 system is advice worth taking.
EcoFlow carries a different caveat. In early 2025 it tested subscription paywalls for advanced app features before community backlash paused the plan, and a whole-home setup run through EcoFlow's 240 V Smart Home Panel 10A5 is exactly the kind you manage from that app. Neither brand's record is a footnote on a system this permanent.

Weekend Camping

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 + 3×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 + 3×B500
Both survive the night. The EP900 + 3×B500 finishes at 13% used with 11,003Wh left — 6.7 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 + 3×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 + 3×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 what a whole-home unit most needs, 120/240 V split-phase at 30 A from a 7,200 W inverterA1, for $3,199 against $13,798. The BLUETTI's 14,880 Wh is within reach: three TITAN packs make 15,052.8 Wh (3 × 5,017.6) inside a 30,105.6 Wh ceilingA7. What the TITAN can't add is the EP900's extra 1,800 W of output (9,000 − 7,200) or its 9,000 W solar input, so a house that must run more than 7,200 W at once, or plans to live off a big array, should pay for the BLUETTI.

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 + 3×B500 rates 4.2/5 (54th 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 + 3×B500 (466 lbs) is a wall-installed system — its weight matters to the installer on day one, then never again.
EP900 + 3×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 + 3×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 + 3×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 0.7), 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.

│ 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
Once either of these is wired into a house, support stops being a return window and becomes a long relationship. EcoFlow's record on that front is mixed; BLUETTI's is the least predictable in the category, and goes better when you buy direct. Neither gets a pass, so buy from the maker either way.

Both expand, but the EP900 + 3×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
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow TITAN 5000
Everything on record for the TITAN 5000 comes from EcoFlow's own published ratings, and those establish the frame of this page: 7,200 W of continuous output with 120/240 V split-phase at 30 AA1, an L14-30 twist-lock beside three 20 A socketsA2, 4,000 W of solar input across 40–450 VA3, and a 5,017.6 Wh packA6 that grows to 30,105.6 WhA7. Our arithmetic on the pack voltage points to LFP cellsA12.
“7,200 W continuous output with 120/240 V split-phase at 30 A.”
BLUETTI EP900 + 3×B500
What exists on this bundle is thin: owner reports from months of use are scarce, and much of the commentary is review content or pre-purchase discussionB0. The installed-system details get the warmest notice, with a reviewer singling out the heavy-duty DC disconnect as more reliable long term than a switchB9 and a forum poster liking the slim cabling between batteriesB4. One owner relayed BLUETTI support's word that the EP900 keeps an Enphase array running off-gridB8. The outdoor enclosure gets mentioned as a plusB5, with a counterpoint from another poster about real heat and long cold spellsB6.

Who Should Buy Which
Buy the TITAN 5000 if you…
- →The homeowner with a 240 V well pump or a split-phase subpanel to feed, whose must-run loads at any one moment stay under 7,200 W, and who would rather keep the $10,599 than prepay for capacityA1.
- →The buyer who wants to start with one 5,017.6 Wh pack and add batteries after the first long outage shows what's needed, up to 30,105.6 WhA7.
- →The house with a utility room to put it in, planning to connect through a 30 A twist-lock inlet or EcoFlow's 240 V Smart Home Panel 10A2A5.
- →Your permit office or insurer asks for listed storage: EcoFlow lists the TITAN 5000 as UL 9540 certified and tested to UL 9540AA15.
Buy the EP900 + 3×B500 if you…
- →The house whose simultaneous load runs past 7,200 W during an outage, which wants a 9,000 W inverter wired into the panel.
- →The solar-first household that plans a big array and wants 9,000 W of panels feeding 14,880 Wh from the first day, rather than stretching a 4,000 W input across extra packs.
- →The Enphase household that wants its existing solar to keep producing during a grid outage, which one owner relayed BLUETTI support confirming for the EP900B8.
If neither fits
If every circuit you need is 120 V, you'd be paying for split-phase on both; EcoFlow's TITAN 5000 Classic uses this same pack and chassis on 120 V onlyA6A13. And if you only need a fridge and a router through the odd short outage, both are overkill, and a far smaller portable station does that job.
The Bottom Line
Both make 240 V; only one makes you pay for all of its capacity on day one. The TITAN 5000 delivers 7,200 W of split-phase for $3,199 and grows past the bundle's battery a pack at a time, while the BLUETTI's $13,798 buys 1,800 W more inverter and a 9,000 W solar door the TITAN can't widen. If your house runs under 7,200 W at once and the grid, not a giant array, is your recharge plan, buy the TITAN 5000.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Does the EcoFlow TITAN 5000 do 240V?
Yes. EcoFlow rates it at 7,200 W continuous with 120/240 V split-phase at 30 A, delivered through an L14-30 twist-lock on the unit. The BLUETTI EP900 + 3×B500 also feeds 240 V, wired directly into the panel, at up to 9,000 W.
How many TITAN 5000 batteries match a BLUETTI EP900 with three B500s?
Three. The base unit plus two extra packs comes to 15,052.8 Wh (3 × 5,017.6), just past the bundle's 14,880 Wh, and the frame takes up to six for 30,105.6 Wh. Nothing on EcoFlow's label says extra packs raise the 7,200 W output or the 4,000 W solar input.
Is 7,200W enough to back up a whole house?
It's enough for a lot of house at once, but it's a hard ceiling: add up everything that must run at the same moment, and if it passes 7,200 W the TITAN can't carry it. The BLUETTI's 9,000 W gives 1,800 W more room (9,000 − 7,200). Below 7,200 W, that extra width does nothing for you.
Is the BLUETTI EP900 worth the extra money over the TITAN 5000?
Only for a house that needs more than 7,200 W at once or plans to run on a solar array bigger than 4,000 W. The gap is $10,599, and capacity alone doesn't justify it, because the TITAN grows past the bundle's 14,880 Wh with two packs. Price those packs before deciding.
Where should a TITAN 5000 be installed?
Indoors, in a utility space away from bedrooms and living areas, per EcoFlow's label. It charges only between 0 °C and 45 °C (32 °F to 113 °F), so an unheated space that freezes is a poor home if you're counting on solar to refill it.
What does the TITAN 5000 add beyond the spec sheet?
EcoFlow lists UL 9540 certification and UL 9540A testing, and sells the TITAN 5000 with a factory pre-wired Smart Home Panel 10 that gives app control of 10 circuits. It also lists AC coupling with compatible existing rooftop solar, which needs that panel and a CT sensor. EcoFlow says X-Fusion 2.0 lets solar power the home first and the battery cover peak-rate hours, and Storm Mode charges the battery ahead of severe weather. OASIS 3.0, which learns household habits and forecasts solar up to 3 days ahead, is marked a subscription feature in the EcoFlow app.
