Head-to-head test
EcoFlow TITAN 5000 vs BLUETTI EP800 + 2×B500
Both feed a split-phase panel within 400 W of each other, so the decision is how much battery to buy up front: the TITAN 5000 starts at half the EP800 pair's storage for less per watt-hour and grows a pack at a time, while the BLUETTI is for the buyer who wants 9,920 Wh and a 9,000 W solar input on day one.

Spec deltas
The TITAN 5000 and the BLUETTI EP800 with two B500 packs both do the hard part of home backup: split-phase 120/240 V, the kind that runs a well pump or an air-conditioning condenser. The TITAN puts out 7,200 WA1 and the EP800 7,600 W, close enough that output won't decide this.
Battery will. The EP800 pair holds 9,920 Wh to the TITAN's 5,017.6, nearly twice as much, and costs $6,999 to the TITAN's $3,199. Per watt-hour the EcoFlow is the cheaper buy, and it doesn't ask you to commit to the bigger bank before your first long outage tells you whether you need it.
So the TITAN 5000 wins at moderate confidence. The EP800 is the better buy for a house with a big solar array and outages that routinely run past two nights.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
continuous output
That gives the TITAN two ways into a house: through a generator-style inlet and interlock, or through EcoFlow's 240 V Smart Home Panel 10, which it's sold bundled withA5. The EP800 has one way, hardwired by an electrician, and is inert until that's done. Neither is plug-and-play for a whole house, but only the TITAN is useful off its own sockets the day it arrives.
TITAN 5000: 7,200 W continuous at 120/240 V split-phase, 30 AA1TITAN 5000 outlets: three NEMA 5-20R sockets and one L14-30 twist-lock marked 120V/240V 30AA2EP800 + 2×B500: hardwired 120/240 V at 7,600 W, no sockets on the unit
Why it mattersIf you want backup this month and a proper panel install when the budget allows, the TITAN fits that order of events and the EP800 doesn't.
Capacity
So the EP800's head start is a purchase, not a permanent advantage. You can start at 5,017.6 Wh, live through a season of outages, and add the second pack only if the first one ran short. The extra pack is priced separately, so add it in before calling a two-pack TITAN the cheaper route to the EP800's size; the point is that you decide when to spend it.
TITAN 5000 pack: 5,017.6 WhA6Expandable to 30,105.6 Wh in six packs, each extra matching the base unitA7EP800 + 2×B500: 9,920 Wh, expandable with more BLUETTI batteries
Why it mattersBuyers who don't yet know how long their outages run should start with the TITAN and let the first winter size the rest.
solar input
That's the EP800's real edge in a long outage. A sunny day can put back roughly twice the energy, into a bank that already had 4.1 spare nights after the first where the TITAN had 1.6. Through a multi-day storm with a large array on the roof, the BLUETTI is the one still comfortable on day four.
TITAN 5000 solar: 40–450 V, 4,000 W maxA3EP800 + 2×B500 solar: 9,000 W max8-Hour Blackout: TITAN 5000 ends at 39% used with 1.6 more nights left; EP800 at 20% with 4.1 more
Why it mattersWith a large array and outages measured in days, the EP800's solar input justifies the gap; with a small array or the grid back by morning, it doesn't.
The specific dimensions that decide these two units — everything else is a tie.
Growth Path
Selected because: One extra EcoFlow pack takes the TITAN 5000 past the EP800 pair's 9,920 Wh, so the BLUETTI's capacity lead is less permanent than the spec table makes it look.
solar input
The EP800 pair's capacity lead is one EcoFlow pack wide. Add an EF-TT-E5-G1 and the TITAN doubles past the BLUETTI's 9,920 Wh, with room to keep going to six packs and 30,105.6 WhA7. The EP800 expands too, with more BLUETTI batteries, so neither of these is a ceiling you'll hit by accident.
Solar is the gap that doesn't close. The TITAN's 4,000 W inputA3 stays put as packs pile on, so each one you add stretches the same sunny day further. The EP800's 9,000 W was sized for a big bank from the start, and it's the one growth argument the BLUETTI wins outright.
Runtime: Will It Power Your Gear?
Selected because: With split-phase output within 400 W of each other, runtime is where nearly double the battery actually shows up.
continuous output
After the flat 85% derate the TITAN has 4,265 Wh to spend and the EP800 pair 8,432 Wh, so any load on the table runs just under twice as long on the BLUETTI. Output barely separates them at 7,200 W against 7,600 W. The table is really a picture of battery size.
That makes the purchase easy to frame: the EP800 is a longer outage, not a bigger house. If yours are evenings and the occasional overnight, the TITAN's column covers them and the rest is money you never needed to spend.
Brand Trust
Selected because: Battery lock-in and BLUETTI's support record both weigh more on a system wired into your panel.
Once the EP800 is wired into a subpanel it doesn't go back in a box, so the back end matters. One would-be buyer on the DIY Solar forum pointed out that if the EP800's inverter fails, its batteries won't run on any other inverterB4. That trade-off comes with any closed battery system, and it's worth knowing before you buy B500s to grow it.
Our brand profile adds the support picture: BLUETTI's record is the least consistent in the space and runs mostly on email, while EcoFlow's is polarized rather than clean. Neither moves the verdict, but both argue for buying from the channel that makes a claim easiest.

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 + 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.

EP800 + 2×B500
Both survive the night. The EP800 + 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.

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 + 2×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
Take the TITAN 5000. It matches the EP800 system on the hard part of home backup, 120/240 V split-phase, at 7,200 W against 7,600 WA1, and it does it for $3,199 against $6,999, which is less per watt-hour for 5,017.6 Wh against 9,920. One more EcoFlow pack doubles it past the BLUETTI's capacity whenever your outages prove you need itA7. Choose the EP800 if you want the full 9,920 Wh installed at once and a roof big enough to use its 9,000 W solar input; that buyer pays the $3,800 gap for real capability.

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 + 2×B500 rates 3.6/5 (18th 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 + 2×B500 (360.6 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 + 2×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 + 2×B500: Noise Level Not Disclosed
The TITAN 5000 publishes its noise level (39dB); the EP800 + 2×B500 doesn't publish one. That isn't evidence the EP800 + 2×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 + 2×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 tier as a home system rather than a gadget: EcoFlow pairs the TITAN with its own smart home panel, while BLUETTI wires the EP800 straight into a subpanel. The apps are close, with BLUETTI's rated level with the best in the category on both stores and EcoFlow's strong on iOS and a little lower on Android. EcoFlow brings the largest community in the space for working through problems yourself, which counts whenever either maker's support is slow.

Analyst note
Both expand, but the EP800 + 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
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, and they set out the split-phase case cleanly: 7,200 W at 120/240 V and 30 AA1, three 5-20R sockets plus an L14-30 twist-lockA2, 4,000 W of solar at 40–450 VA3, and an AC IN/OUT port whose bypass mode passes up to 7,200 W through to the outletsA14. EcoFlow's product image shows the display at 4.00 kW in and 7.20 kW outA4. All of it is the maker's label and store page, read by usA0.
“7,200 W continuous output with 120/240 V split-phase at 30 A.”
BLUETTI EP800 + 2×B500
What exists on the EP800 comes mostly from people deciding whether to buy one; our research found no owner reviews of this exact two-B500 setupB0. Among those forum posters, one put it bluntly: BLUETTI's reputation for support is not greatB3.
The one hands-on EP800 report is a setup snag: a user placed the CT clamp on L1 with the arrow toward the grid, as directed, and the app still showed no home consumptionB7. It's a single report, and a monitoring problem rather than a power one, but it's worth raising with your installer before they leaveB7.
“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.”

- →The homeowner with a large rooftop array who wants 9,000 W of solar feeding 9,920 Wh from the first day.

If neither fits
If the goal is the whole house running as normal, central air included, through a week-long outage, both of these are the wrong category. That's a standby generator's job, or an installed battery bank sized well beyond either.
The Bottom Line
Buy the TITAN 5000. It gives you the same class of split-phase output as the EP800 pair, 400 W short, for $3,199, and the one thing the BLUETTI has more of, battery, is a single EcoFlow pack away whenever your outages prove you need it.
Spend the $3,800 on the EP800 only if a big array is going on the roof and your outages are measured in days. Otherwise start with half the battery and let the weather decide the rest.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Can the EcoFlow TITAN 5000 power a whole house like the BLUETTI EP800?
It can feed a home's split-phase panel, which is the part that matters: 7,200 W at 120/240 V against the EP800's 7,600 W. EcoFlow sells it bundled with its 240 V Smart Home Panel 10 for exactly that job. How much of the house it carries comes down to what runs at once; the EP800's extra 400 W and nearly double the battery buy more headroom and more hours.
How many TITAN 5000 batteries equal one EP800 with two B500s?
Two. The base unit plus one EcoFlow extra pack makes 10,035.2 Wh, slightly more than the EP800 pair's 9,920 Wh, because each extra pack matches the base unit's 5,017.6 Wh. The extra pack is a separate purchase, so price it before comparing totals.
Is the EP800 cheaper per kWh than the TITAN 5000?
No. $6,999 for 9,920 Wh works out to more per watt-hour than $3,199 for the TITAN's 5,017.6 Wh. What the EP800's extra money buys is a bigger bank, 400 W more output and 9,000 W of solar input against the TITAN's 4,000 W, not a better rate.
Which recharges faster from solar, the TITAN 5000 or the EP800?
From empty at full rated input, about the same: each needs a little over an hour, because the EP800's 9,000 W is filling nearly twice the battery that the TITAN's 4,000 W fills. The BLUETTI's advantage is energy banked per sunny day, which matters most in outages that last several days.
Does the TITAN 5000 work with the rooftop solar I already have?
EcoFlow says the TITAN series AC couples with compatible existing rooftop solar, which needs the Smart Home Panel 10 and a CT sensor. X-Fusion 2.0 has that solar power the home first and the battery cover peak-rate hours. Confirm your inverter is compatible with your installer before counting on either.
