Head-to-head test
EcoFlow TITAN 5000 Plus vs BLUETTI EP800 + 2×B500
The Plus's big numbers need a source behind them: its 10 kW needs solar or grid power flowing in and its 8 kW charging needs a 240 V feed, so in a night-time blackout it's a 7,200 W, 5,017.6 Wh battery facing the EP800 pair's 7,600 W and 9,920 Wh at about the same price per watt-hour.

Spec deltas
EcoFlow's label rates the TITAN 5000 Plus at 10 kW total, then adds the fine print that matters: 7,200 W for discharge onlyA1. The rest needs solar or grid power flowing in at the same time. When the grid goes down at night, the Plus is a 7,200 W battery, and the BLUETTI EP800 with two B500 packs is a 7,600 W one with nearly twice the storage.
That changes how the price reads. The Plus costs $3,699 for 5,017.6 Wh; the EP800 pair costs $6,999 for 9,920 Wh. Per watt-hour they land close together, so the BLUETTI's extra spend buys battery at roughly the Plus's own rate, then adds 400 W more output and a 9,000 W solar input against the Plus's 8,000.
The Plus earns its place in one kind of house: one with a 240 V generator. Its AC IN/OUT port accepts up to 7,660 W of charge-only input at 120/240 VA15, so a big enough generator refills it in under an hour and shuts off. Without that, the EP800 is the stronger whole-home buy.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
continuous output
So the 41.7 A rating is a 10 kW figure, fully live only while solar or grid power is flowing in. In a night-time blackout the number running your house is 7,200 W, 400 W below the EP800. The Plus's biggest outlet is sized for a load it can only fully feed with solar or utility power arriving at the same time.
Plus label: Total Output 10 kW Max, 7,200 W for discharge onlyA1Plus split-phase rating: 120/240 V at 41.7 A, on a 14-50-pattern outletA2A3EP800 + 2×B500: 7,600 W continuous output
Why it mattersAnyone choosing the Plus for its 14-50-pattern outlet should treat it as a grid-up spec; on battery alone, the EP800 delivers more.
That changes what a generator does in your plan. Instead of running all night to carry the house, a 240 V generator big enough to feed the port can refill the Plus in under an hour, then go quiet while the battery takes over. Our record carries no grid-charging rate for the EP800, so this is the Plus's own trick rather than a measured win over the BLUETTI, but it's the reason to pay Plus money at all.
Plus AC IN/OUT: 120/240 V split-phase input, up to 7,660 W charge-onlyA15Plus pack: 5,017.6 WhA7Plus display shows 8.00 kW in, twice the TITAN 5000's 4.00 kWA5
Why it mattersIf a 240 V generator already lives in your garage, the Plus turns it into a fast charger, and the verdict tilts to the EcoFlow.
solar input
In the outage these systems are bought for, grid down and no generator, the sun is the only refill, and there the Plus has little extra to sell. The EP800 takes 1,000 W more solar into a bank nearly twice the size.
Plus solar input: 2 inputs, 40–450 V, 4,000 W each, 8,000 W totalA4The 8.00 kW display figure is the 240 V AC charging path, not the solar inputA15EP800 + 2×B500 solar input: 9,000 W
Why it mattersSolar-first buyers without a generator should lean EP800: it takes more solar and nearly twice the battery, and the Plus's charging advantage lives on a 240 V cable, not on the roof.
The specific dimensions that decide these two units — everything else is a tie.
Runtime: Will It Power Your Gear?
Selected because: On battery the Plus gives 7,200 W from 5,017.6 Wh and the EP800 pair 7,600 W from 9,920 Wh, and runtime is where that gap becomes hours.
continuous output
Run the battery figures and the EP800 pair carries any load on the table just under twice as long: 8,432 Wh usable after the flat 85% derate against the Plus's 4,265 Wh. The Plus doesn't buy any of that back with output, either. On battery it gives 7,200 W, 400 W under the BLUETTI.
Refill is the one place the Plus rewrites that table, and only with the right cable. Its 120 V wall inlet is rated 15 AA9; the fast path is the 240 V AC IN/OUT port. In an outage that means a generator, or the runtime column is all you get.
Your Life, Your Pick
Selected because: The 8-hour blackout row counts the nights each holds after the first, which is the EP800's case when no generator is in the plan.
The 8-hour blackout row is the EP800's argument in miniature. Both carry the 1,645 Wh night; the BLUETTI ends at 20% used with 6,787 Wh in reserve, the Plus at 39% with 2,620 Wh. That's 4.1 more nights against 1.6 before anyone has to think about recharging.
The CPAP and remote-workday rows decide nothing, with both units finishing on most of their battery. The Plus can close the gap two ways: a generator, which turns its 1.6 nights into a floor it refills from rather than a countdown, or one more EcoFlow pack, which doubles it past the EP800's 9,920 WhA8 at the price of a separate purchase.
Brand Trust
Selected because: Out-of-warranty repair is thin at both makers, which matters on a system meant to stay in a utility room for years.
Both makers are at their weakest after the warranty, which is exactly when a home system is still on the wall. EcoFlow offers no parts or service out of warranty; BLUETTI has no spare-parts policy for some models, and older units may become unrepairable. Budget for a fault years from now being a replacement conversation with either brand.
Day to day, BLUETTI's support is the least consistent in the space and runs mostly on email, while EcoFlow's is polarized. That's a reason to buy the EP800 direct from BLUETTI, where outcomes tend to be better, not a reason to change the verdict.

Neither unit
Scoring these two at a campsite is a category error: the TITAN 5000 Plus at 121.3 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.

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 EP800 + 2×B500, on Power Score margin
Take the EP800 with two B500s unless you own a 240 V generator. On battery, which is all an outage leaves you, the Plus delivers 7,200 WA1 against the EP800's 7,600 W, from 5,017.6 Wh against 9,920, with 8,000 W of solar against 9,000A4. At $3,699 against $6,999 the two cost about the same per watt-hour, so the BLUETTI's extra money buys proportionally more battery, plus more output and 1,000 W more solar. The Plus's genuine edge is a 240 V charge-only input of up to 7,660 WA15: with a generator big enough to feed it, the pack refills in under an hour, and that lets a smaller battery do a bigger job.

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 Plus rates 4.7/5 (84th 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 Plus (121.3 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 Plus's 5 years. An underrated factor if you're keeping this unit for years.
EP800 + 2×B500: Noise Level Not Disclosed
The TITAN 5000 Plus 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 Plus'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 Plus 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
BLUETTI sells itself as the value brand and EcoFlow sits mid-to-premium, but at this size both are selling a home system, not a gadget. EcoFlow's edge is depth: the larger ecosystem and the largest community in the space to troubleshoot with. BLUETTI's is breadth, with one of the widest lineups in portable power and dual-voltage flagships like the EP800 at the top.

What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow TITAN 5000 Plus
The evidence so far is EcoFlow's own published ratings, and they spell out what the Plus adds and what it doesn't. The label's 10 kW total carries the note that discharge stops at 7,200 WA1; the split-phase rating is 41.7 AA2; and the AC IN/OUT port accepts up to 7,660 W charge-only from a 240 V feedA15. The pack is the same 5,017.6 Wh as the rest of the TITAN 5000 lineA7, and the label limits charging to 32 °F through 113 °FA12, worth knowing if your utility space is an unheated garage.
“"Total Output: 10 kW Max (7200W for discharge only)" — the battery delivers 7,200 W, the same as the TITAN 5000; the 10 kW total includes grid pass-through.”
BLUETTI EP800 + 2×B500
Our research turned up no owner reviews of the EP800 with two B500s; what exists is mostly forum talk from people pricing one upB0. The tone is cautiousB5. One poster hadn't seen it tested and doubted BLUETTI's habit of oversimplifying how much energy a house takesB5; another liked that a modular EP system could move house with you, unlike a fixed wall batteryB6.
The warmest report concerns a sibling: an owner on SolarQuotes running an EP760 with eight B500s describes flawless operation and seamless switchingB8. The batteries are shared and the inverter isn't, so read it as a note on BLUETTI's build quality rather than evidence about the EP800 itselfB8.
“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.”

“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 Plus if you…
- →The house with a 240 V generator big enough to feed the AC IN/OUT port: the Plus refills at up to 7,660 WA15, so the generator runs for under an hour instead of all night.
- →The buyer who wants split-phase backup for roughly half the EP800's outlay and something useful before the electrician comes: two 120 V 20 A sockets and a 14-50-pattern outlet work off the boxA3, and packs can be added laterA8.
- →A buyer whose permit or insurer asks for UL 9540: EcoFlow lists the Plus as certified and tested to UL 9540AA16; check the EP800 stack's listing for the same standard before you compare.
Buy the EP800 + 2×B500 if you…
- →The household that rides out outages on battery and sun alone, with a roof that can feed 9,000 W.
- →Anyone running heavy 240 V loads in a blackout, where 7,600 W from battery beats the Plus's 7,200.
- →The family whose outages last days, where 9,920 Wh banks far more nights of the blackout load than 5,017.6 Wh does.
If neither fits
If your house regularly pulls more than 7,600 W at once, say an electric range, a dryer and central air together, neither inverter keeps up during an outage. That house needs load management at the panel or a standby generator sized to the whole service, not a choice between these two.
The Bottom Line
Buy the EP800 with two B500s. In the outage you're actually buying for, it gives you 400 W more than the Plus and nearly twice the battery at about the Plus's own price per watt-hour, with 1,000 W more solar input.
The Plus wins one house: the one with a 240 V generator already in the garage, where its charging path turns a half-size battery into one that never stays empty for long. Everyone else would be paying for a 10 kW figure that only shows up while the grid is still on.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Does the EcoFlow TITAN 5000 Plus really output 10 kW?
Not from its battery. EcoFlow's label lists 10 kW total with 7,200 W for discharge only; the rest needs solar or grid power flowing in at the same time. In a night-time blackout the Plus delivers 7,200 W, which is 400 W less than the BLUETTI EP800's 7,600 W.
How fast does the TITAN 5000 Plus charge from a generator?
Up to 7,660 W, through its AC IN/OUT port fed at 120/240 V. At that rate the 5,017.6 Wh pack refills in under an hour on paper, provided the generator can actually supply it. The 120 V wall inlet is a slower path; solar reaches 8,000 W across two inputs but needs the panels to match.
Is the BLUETTI EP800 with two B500 batteries better value than the TITAN 5000 Plus?
Per watt-hour they're close: $6,999 for 9,920 Wh against $3,699 for 5,017.6 Wh. The difference is what else the money buys. The EP800 adds 400 W more battery output and 9,000 W of solar input against the Plus's 8,000 W, which makes it the stronger system for an outage carried on battery and sun.
What does the TITAN 5000 Plus have that the EP800 doesn't?
Outlets on the box and a fast 240 V charging input. The Plus carries two 120 V 20 A sockets and a 14-50-pattern outlet, where the EP800 has no sockets and works only once hardwired, and it accepts up to 7,660 W of 240 V charging. On storage, battery output and solar, the EP800 is ahead.
What does the TITAN 5000 Plus add beyond the spec sheet?
EcoFlow lists it as UL 9540 certified and tested to UL 9540A, with a factory pre-wired Smart Home Panel 10 controlling 10 circuits from the app. It adds X-Boost 2.0, up to 5 kW on each 120 V leg, and X-Fusion 2.0, where solar powers the home first and the battery covers peak-rate hours. EcoFlow also sells a 7-day installation service in limited ZIP codes.
