Head-to-head test
EcoFlow TITAN 5000 vs BLUETTI EP800 + 3×B500
With split-phase on both and output only 400 W apart, the extra money for the EP800 stack buys stored energy and nothing else, so the call turns on whether your outages last a night or a week.

Spec deltas
The TITAN 5000 runs 120/240 V split-phase at 7,200 WA1; the BLUETTI EP800 + 3×B500 runs 120/240 V at 7,600 W. On the spec that decides most whole-home comparisons, that's a draw, and it means both can feed the same 240 V circuits.
They part ways at the tank. The EP800 stack holds 14,880 Wh to the TITAN's 5,017.6 WhA6, nearly three times as much, and costs $3,100 more. Per watt-hour that's a fair deal. It's also a lot of watt-hours to prepay for before you know you'll use them.
One blackout night uses 39% of the TITAN's usable charge. If your power comes back by breakfast, buy the TITAN 5000 and add packs when your outages give you a reason. If it comes back next week, the EP800 stack is already the size you'd grow into.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
continuous output
So the price gap isn't buying reach. It buys 9,862 Wh more in the tank (14,880 minus 5,017.6) and 5,000 W more solar input (9,000 against 4,000). That's endurance: the TITAN 5000 runs the same loads, just for fewer hours.
TITAN 5000: 7,200 W continuous, 120/240 V split-phase at 30 AA1EP800 + 3×B500: 7,600 W continuous, hardwired 120/240 VStored energy: 5,017.6 Wh against 14,880 Wh
Why it mattersIf 240 V is what drew you to the EP800, you don't have to pay BLUETTI money for it; the TITAN 5000 has it at the lower price.
Three TITAN packs come to 15,052.8 Wh (3 × 5,017.6), just past the BLUETTI's 14,880, so the size you'd buy the EP800 for sits two packs away. The difference is timing: with the TITAN, you buy that endurance when your outages prove you need it, not before.
8-Hour Blackout: TITAN 5000 at 39% used, 2,620 Wh left, 1.6 more nights8-Hour Blackout: EP800 + 3×B500 at 13% used, 11,003 Wh left, 6.7 more nightsTITAN 5000 extra batteries each match its 5,017.6 Wh, up to six packsA7
Why it mattersHouseholds that lose power a night at a time should start with the TITAN 5000; anyone with multi-day outages should price the TITAN plus two extra packs against the EP800 stack before choosing.
solar input
The TITAN's solar input doesn't grow with its bank. A six-pack TITAN behind the same 4,000 W needs about seven and a half hours of full-rated sun (30,105.6 Wh over 4,000 W), which few real days hold. The EP800's input is already sized for a large bank.
TITAN 5000 solar input: 40–450 V, 4,000 W maxA3EP800 + 3×B500 solar input: 9,000 WTITAN 5000 ceiling: 30,105.6 Wh in six packsA7
Why it mattersIf grid independence on a big array is the goal, the BLUETTI's solar input is a reason to pay more; if solar is a top-up, it isn't.
The specific dimensions that decide these two units — everything else is a tie.
Runtime: Will It Power Your Gear?
Selected because: With 240 V and output nearly matched, stored energy is the one thing the price gap buys.
continuous output
Count it in nights rather than watt-hours. After the eight-hour blackout load, the TITAN 5000 has 2,620 Wh left and the EP800 stack 11,003 Wh, which is one and a half more nights against nearly seven.
Which of those you need is a question about your grid, not either machine. A thunderstorm that drops the power overnight is a TITAN night. An ice storm that takes the lines down for a week is what the BLUETTI's extra tank is for, and it's the only reason on this page to spend the difference.
Growth Path
Selected because: The TITAN 5000 can add packs past the EP800 stack's size, but its solar input stays where it is.
solar input
The TITAN 5000 grows in 5,017.6 Wh steps to 30,105.6 WhA7, and its 7,200 W split-phase output serves every one of themA1. You can buy the 240 V capability now and the energy later, in whatever steps your outages ask for. Two extra packs put it level with the EP800 stack as configured here.
What stays fixed is the 4,000 W solar inputA3. The EP800 stack expands too, and its 9,000 W input is the one built to keep a large bank fed from the roof. Grow the TITAN for blackout endurance; grow the BLUETTI if you're chasing off-grid.
Your Life, Your Pick
Selected because: Everyday loads barely register on either, so the blackout row is the only one that separates them.
Daily loads barely register on either. A remote workday takes 21% of the TITAN's usable charge and 7% of the BLUETTI's; a night of CPAP, 8% and 3%. Both finish with thousands of watt-hours unused, so these rows confirm what you'd guess: nobody chooses between these for a laptop. The blackout row is where the BLUETTI's extra tank finally earns a line.
Brand Trust
Selected because: Both expand with their own maker's batteries, so the support record comes with the purchase.
Both are one-maker stacks. The TITAN expands with EcoFlow's own EF-TT-E5-G1 packA7, and one forum member, possibly describing a sibling model, warned that the EP800's batteries won't work with any other inverter if its head unit failsB4. You're buying a support relationship along with the hardware, for as long as you own it.
That makes the support records the real brand comparison. A forum member weighing an EP800 summed up BLUETTI's support reputation as not greatB3, and the brand profile agrees: email-heavy, slowed by time zones, better for direct buyers. EcoFlow's US phone and chat line is polarized rather than poor, which on a wired-in system is the better of two imperfect bets.

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 EP800 + 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.

EP800 + 3×B500
Both survive the night. The EP800 + 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.

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 EP800 + 3×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 runs 120/240 V split-phase at 7,200 W through an L14-30 on the unitA1A2, within 400 W of the EP800 stack's 7,600 W, for $3,100 less. A blackout night takes 39% of its usable charge, and extra packs take it to 30,105.6 Wh when that stops being enoughA7. The EP800 + 3×B500 is the better buy only if your outages routinely run past a couple of nights or you're feeding a 9,000 W roof array from day one.
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 EP800 + 3×B500 rates 4.0/5 (43rd percentile of 29 Whole-Home / Off-Grid-class units).

Weight Reality Check
Neither unit is grab-and-go. The TITAN 5000 (119 lbs) is a two-person lift. The EP800 + 3×B500 (483.6 lbs) is a wall-installed system — its weight matters to the installer on day one, then never again.
Warranty: 10 Years vs 5
The EP800 + 3×B500 is covered for 10 years against the TITAN 5000's 5 years. An underrated factor if you're keeping this unit for years.
EP800 + 3×B500: Noise Level Not Disclosed
The TITAN 5000 publishes its noise level (39dB); the EP800 + 3×B500 doesn't publish one. That isn't evidence the EP800 + 3×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 EP800 + 3×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 build their 240 V home setups from their own batteries, so the brand you pick now is the brand you expand with. EcoFlow brings the larger ecosystem and community with a polarized support record; BLUETTI brings an app rated as well as any and the category's least consistent support. On a stack an electrician has wired in, the support half of that matters most.

Analyst note
Both expand, but the EP800 + 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.

BLUETTI EP800 + 3×B500
What exists on the EP800 is forum talk before purchase rather than owner reports after installation, and none of it covers the three-battery configuration on this pageB0. Price is the theme that repeats: prospective buyers see a strong product priced beyond what most will payB1B2. These entries may refer to a sibling model, so read them for character, not specsB0.
One forum post describes a CT clamp fitted on L1 that still left home consumption missing from the appB7, the kind of setup snag an installed system can bring. The warmest account comes from a sibling EP760 install on B500 batteries, described as flawless, with build quality to matchB8.
“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.”

Who Should Buy Which
Buy the TITAN 5000 if you…
- →Your outages are overnight events and you want 240 V circuits covered: 7,200 W of split-phase through the L14-30 or EcoFlow's 240 V Smart Home Panel 10A2A5.
- →You'd rather grow into capacity than prepay for it: packs take the TITAN 5000 to 30,105.6 WhA7 without changing a thing about what it can power.
- →A buyer whose permit or insurer asks for UL 9540: the TITAN 5000 is certified and tested to UL 9540AA15.
Buy the EP800 + 3×B500 if you…
- →You've sat through outages that lasted days: the EP800 stack ends a blackout night with nearly seven more in reserve.
- →You're building a large roof array toward grid independence: 9,000 W of solar input against the TITAN's 4,000 WA3.
If neither fits
If a long outage at your place means running central air and an electric range for a week straight, neither battery is the efficient tool. A standby generator with its own fuel supply is the category to price.
The Bottom Line
Buy the TITAN 5000. It matches the EP800 stack on split-phase and comes within 400 W on output, so the BLUETTI's extra cost buys endurance, not capability.
If your outages last a night, that endurance would sit on the wall unused. If they last a week, the EP800 stack is the size you'd build toward anyway, and buying it whole is the simpler road. Decide which house you live in, then buy the one that fits it.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Does the EcoFlow TITAN 5000 have 240 V like the BLUETTI EP800?
Yes. It's rated 7,200 W continuous at 120/240 V split-phase, 30 A, delivered through an L14-30 twist-lock on the unit or EcoFlow's 240 V Smart Home Panel 10. The EP800 + 3×B500 is hardwired at 120/240 V with 7,600 W, so both can serve 240 V circuits.
Why does the EP800 + 3×B500 cost so much more than the TITAN 5000?
Mostly battery. The BLUETTI stack holds 14,880 Wh to the TITAN's 5,017.6 Wh and takes 9,000 W of solar against 4,000 W. Per watt-hour it's the cheaper of the two; in total it's $3,100 more.
Can the TITAN 5000 be expanded to match the EP800 + 3×B500?
Yes. Each EcoFlow extra battery matches the base unit's 5,017.6 Wh, up to six packs and 30,105.6 Wh. Three packs in total come to 15,052.8 Wh, just over the BLUETTI stack's 14,880 Wh. Price the two extra packs before treating that as the cheaper route.
Which lasts longer in a blackout, the TITAN 5000 or the EP800 + 3×B500?
The EP800 + 3×B500, by a wide margin. On the engine's eight-hour blackout load it finishes at 13% used with nearly seven more nights in hand; the TITAN 5000 finishes at 39% with about one and a half. Both clear the first night easily.
What does the TITAN 5000 add beyond the spec sheet?
The TITAN 5000 is UL 9540 certified and tested to UL 9540A, and it comes with a factory pre-wired Smart Home Panel 10 with app control of 10 circuits. EcoFlow sells a 7-day installation service in limited ZIP codes, and says you can take the modular system with you when you move. OASIS 3.0 forecasting is marked a subscription feature in the EcoFlow app.
