Head-to-head test
EcoFlow TITAN 5000 vs BLUETTI 2×EP800 + 4×B500
Both run 240 V, so the question is how much at once: the TITAN 5000 tops out at 7,200 W and the BLUETTI at 15,200 W, and extra packs can match the BLUETTI's energy but never its inverter.

Spec deltas
Both of these run 240 V, which settles the first question a whole-home shopper asks. The TITAN 5000 delivers 7,200 W at 120/240 V split-phaseA1; the BLUETTI 2×EP800 + 4×B500 delivers 15,200 W from a hardwired system. The second question is whether your house ever needs the difference.
Everything else on this page bends toward that one number, because it's the only gap the TITAN can't close. Short on energy? Four packs take it to 20,070.4 WhA7, level with the BLUETTI's 19,840. Short on watts? Packs don't help. The 7,200 W belongs to the inverter, and it stays 7,200 W however many batteries stand behind it.
The BLUETTI costs $14,800 more for 8,000 W of extra headroom (15,200 − 7,200) and a far bigger solar input. Some homes need that. A panel of chosen circuits, with a 240 V load or two among them, doesn't, and for that house the TITAN 5000 is the buy.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
continuous output
So the purchase hinges on simultaneous load, not storage. Storage you can buy later, a pack at a time. Headroom you buy once, on day one, and only the BLUETTI comes with 15,200 W of it.
TITAN 5000: 7,200 W continuous at 120/240 V split-phase, 30 AA1TITAN 5000 expands to 30,105.6 Wh with six packsA7BLUETTI 2×EP800 + 4×B500: 15,200 W, 19,840 Wh
Why it mattersAdd up what has to run at the same moment in an outage: under 7,200 W, the TITAN 5000 does it for $14,800 less; over it, the BLUETTI is the one built for the load.
That's what lets the TITAN 5000 drive a 240 V panel at its full rating: the same kind of job the BLUETTI does from its hardwired subpanel feed, with a lower ceiling and a much lower price.

Why it mattersIf your plan is a transfer panel feeding chosen circuits, a 240 V one among them, the TITAN 5000 covers the installation the BLUETTI would, minus headroom you may never use.
solar input
Build the TITAN out to BLUETTI-sized storage, though, and the solar figure stays at the 4,000 W on the unit's label. Four packs behind that input need about five hours of full output to refill (20,070.4 ÷ 4,000), against about an hour for the BLUETTI's 19,840 Wh on 18,000 W.
TITAN 5000 solar: 40–450 V, up to 4,000 WA3BLUETTI solar input: up to 18,000 WFour TITAN packs: 20,070.4 Wh (4 × 5,017.6)A7
Why it mattersA storm-backup plan with a modest array lives comfortably inside the TITAN's 4,000 W; a plan to run the house off a big roof all year is the BLUETTI's.
The specific dimensions that decide these two units — everything else is a tie.
Your Life, Your Pick
Selected because: Every scenario here peaks at 400 W or less, so it shows the TITAN 5000 has the energy, while the 7,200 W question sits above all of them.
The scenario rows test energy, and the TITAN 5000 has enough of it: our 8-hour blackout leaves it at 39% used, the CPAP night at 8%. The heaviest load anywhere in the grid peaks at 400 W, a rounding error against either inverter.
That's the limit of what this section can say about this pair. Neither unit is stretched by these loads, so the grid can't separate a 7,200 W ceiling from a 15,200 W one. Your own list of 240 V appliances running at the same time can.
Growth Path
Selected because: Packs take the TITAN 5000 to 30,105.6 Wh; its 4,000 W solar input against the BLUETTI's 18,000 W is the growth gap that stays.
solar input
Six packs take the TITAN 5000 to 30,105.6 WhA7, comfortably past this BLUETTI stack's 19,840, and the BLUETTI expands as well. So storage isn't where these two part ways over the years. Solar is: 18,000 W of input on the BLUETTI against 4,000 W on a 40–450 V window for the TITANA3.
That gap only bites if the roof is your main fuel. For a backup plan that tops up between storms, 4,000 W is a generous input for one pack; for an off-grid house living on its array, it's the TITAN's real ceiling.
Runtime: Will It Power Your Gear?
Selected because: The BLUETTI's 16,864 usable Wh against 4,265 is a capacity gap packs can close; this shows what one pack covers first.
continuous output
One TITAN pack holds 4,265 usable watt-hours to the BLUETTI's 16,864, about a quarter of the stored energy. In the blackout row that's 1.6 more nights in reserve against 9.3.
The TITAN's shortfall is the optional kind. Three extra packs make it 20,070.4 WhA7, and you can add them after the first long outage tells you whether you needed them. The BLUETTI asks you to buy all 19,840 Wh up front.

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 2×EP800 + 4×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.

CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Either unit
A CPAP is about 40W for eight hours, so both cover the night with room to spare and capacity decides nothing. Fan noise would — but 2×EP800 + 4×B500 doesn't publish a figure, so there's nothing to hold it to. Buy on price, weight, and whether you can live with a fan you haven't heard.

Conclusion
October 4, 2026
Verdict: the EcoFlow TITAN 5000
Buy the TITAN 5000. It gives you split-phase 120/240 V at 7,200 W through an L14-30A1A2, sold with EcoFlow's 240 V Smart Home Panel 10A5, for $14,800 less than the BLUETTI. Its 5,017.6 Wh gets through our 8-hour blackout load with 2,620 Wh left, and four packs reach 20,070.4 WhA7, just past the BLUETTI's 19,840. What it can't buy back is inverter headroom: the BLUETTI delivers 15,200 W. If your outage plan runs more than 7,200 W of load at the same moment, or a solar array bigger than 4,000 W, that's the BLUETTI's job.
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, TITAN 5000 rates 4.6/5 (79th percentile of 20 Home Backup-class units), and 2×EP800 + 4×B500 rates 4.5/5 (68th 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 2×EP800 + 4×B500 (721.2 lbs) is a wall-installed system — its weight matters to the installer on day one, then never again.
Warranty: 10 Years vs 5
The 2×EP800 + 4×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 0.6), 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.
2×EP800 + 4×B500: Noise Level Not Disclosed
The TITAN 5000 publishes its noise level (39dB); the 2×EP800 + 4×B500 doesn't publish one. That isn't evidence the 2×EP800 + 4×B500 is louder — it means there's no figure to hold it to, and no way to compare the two on this without hearing them. If you're buying for a bedroom, a CPAP, or an apartment, treat the TITAN 5000's 39dB as the only published number on the table — a spec-sheet figure, not a measurement — and look for hands-on reports of the 2×EP800 + 4×B500 before deciding.

│ 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
Both makers sell this as whole-home hardware, which turns support into a years-long relationship. EcoFlow answers by phone from the US with mixed results; BLUETTI's support is the least consistent in the category, so if you choose the EP800 stack, buy it direct from BLUETTI.

Analyst note
Both expand, but the 2×EP800 + 4×B500's higher solar ceiling (18,000W 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
The evidence so far is EcoFlow's own published ratings. The rating label establishes 7,200 W at 120/240 V split-phaseA1, an L14-30 twist-lock alongside three 5-20R socketsA2, solar up to 4,000 WA3, and a 5,017.6 Wh packA6 that expands to 30,105.6 WhA7. The pack voltage works out to 64 LFP cellsA12, by our arithmetic on the label rather than EcoFlow's statement.
“7,200 W continuous output with 120/240 V split-phase at 30 A.”
BLUETTI 2×EP800 + 4×B500
What field evidence exists covers the EP800 platform, not this stack, and comes mostly from forum threads where people weigh the purchase; we can't pin each comment to a modelB0. One forum member doubts BLUETTI's whole-house energy claims until someone tests themB5; another, on BLUETTI's own forum, set up the CT clamp and still saw no home consumption in the appB7. The support reputation draws a flat 'not great'B3.
“Haven't run accross any tests on this yet, but given the Bluetti marketing proclivity of over simplifying what it takes and how much energy it takes to power a house I have some doubts.”

“X-Fusion 2.0: solar powers the home first, then charges TITAN for after dark; at peak rates TITAN runs the home on stored energy, and working with the grid through the main panel it can power loads beyond the backed-up circuits.”

Who Should Buy Which
Buy the TITAN 5000 if you…
- →The house with a 240 V well pump or one 240 V circuit to keep alive alongside the fridge and lights: split-phase at 7,200 WA1 does it through a 30 A twist-lockA2.
- →Someone who wants to start at 5,017.6 Wh and add packs once the first long outage shows what they need, up to 30,105.6 WhA7.
- →The buyer installing EcoFlow's 240 V Smart Home Panel 10A5 to back up chosen circuits rather than the whole service.
- →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 thatA23, while its OASIS 3.0 scheduling is a subscription feature in the appA17.
Buy the 2×EP800 + 4×B500 if you…
- →The home that wants several big 240 V loads running at once with the grid down: 15,200 W of headroom against 7,200 W.
- →The off-grid build feeding from a large array: 18,000 W of solar input against the TITAN's 4,000 WA3.
- →A buyer who wants 19,840 Wh installed on day one rather than built up a pack at a time.
If neither fits
If your outage plan is a fridge, a few lights and the internet, both of these are a whole-home answer to a kitchen-sized question; a large portable station covers it for far less. And if you need no 240 V at all, EcoFlow's TITAN 5000 Classic shares this pack and chassisA6A13 without the split-phase output.
The Bottom Line
The TITAN 5000 wins because it does the 240 V job, the one a whole-home buyer can't do without, for $14,800 less, and because the energy gap it leaves is the kind you close later with packs.
The gap it can't close is 8,000 W of inverter headroom. If you know you'll run more than 7,200 W at once with the grid down, buy the BLUETTI and don't look back. Everyone else: buy the TITAN 5000, and spend some of the difference on whatever the first long outage teaches you.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Can the EcoFlow TITAN 5000 power a whole house?
It powers 240 V circuits up to 7,200 W at once, which covers a panel of chosen circuits, a 240 V one included. It won't carry a house that runs several big 240 V loads together; the BLUETTI's 15,200 W is built for that. EcoFlow sells the TITAN 5000 with its 240 V Smart Home Panel 10 for the chosen-circuits job.
How many TITAN 5000 batteries match the BLUETTI 2×EP800 + 4×B500?
Four packs, the base unit plus three extra batteries, make 20,070.4 Wh (4 × 5,017.6), just past the BLUETTI's 19,840 Wh; the TITAN takes up to six for 30,105.6 Wh. Price the extra batteries before calling that the cheaper route to the same capacity. And the output stays at 7,200 W however many packs you add.
What is the L14-30 outlet on the TITAN 5000 for?
It's a 120/240 V, 30 A twist-lock, and 30 A at 240 V is 7,200 W, the inverter's full rating. That makes it the connection for a 240 V transfer panel or a large 240 V appliance circuit. The three 5-20R sockets beside it handle 120 V loads.
Can the TITAN 5000 take 240V grid or generator power?
Yes. Its AC IN/OUT port takes 120/240 V split-phase or 208Y/120 V input at up to 30 A and, in bypass mode, passes up to 7,200 W through to the outlets. The ordinary wall inlet is 100–120 V at 15 A, so the split-phase port is the one a 240 V feed belongs on.
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.
