Head-to-head test
EcoFlow TITAN 5000 vs Goal Zero Yeti PRO 4000 + Tank PRO 4000 (Yeti PRO 8000)
The TITAN 5000 puts 7,200 W of split-phase 240 V on a house circuit while the Yeti PRO 8000 manages 3,600 W on 120 V only, so the Yeti's bigger battery is asking a higher price to do half the work.

Spec deltas
Only one of these can put 240 V on a house circuit. The TITAN 5000 delivers 7,200 W of 120/240 V split-phase through an L14-30 twist-lockA1A2; our record lists no 240 V output on the Yeti PRO 8000, whose inverter tops out at 3,600 W on 120 V.
That settles more than it looks like it should. A well pump, a dryer or a range on a 240 V breaker is beyond the Yeti at any battery size, and the TITAN 5000 is sold alongside EcoFlow's 240 V Smart Home Panel 10 as whole-home backupA5. It's also the cheaper of the two, $3,199 against $5,999.
The Yeti answers with capacity, 7,988 Wh to 5,017.6 Wh, and that wins every long-night row in the scenario grid. In a 120 V house where the worry is hours rather than watts, it's a fair answer. Anywhere else, the TITAN 5000 does twice the work for less money.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
continuous output
Through the 240 V Smart Home Panel 10 that EcoFlow bundles with itA5, that L14-30 reaches the circuits a 120 V system skips by design: the well pump, the dryer, the range. Paying $2,800 more for the Yeti buys a bigger battery that can never reach them.
TITAN 5000: 7,200 W continuous, 120/240 V split-phase at 30 AA1Outlets: three NEMA 5-20R plus one L14-30 marked 120V/240V 30AA2Yeti PRO 8000: 3,600 W continuous; 240 V output recorded as none
Why it mattersIf any circuit you need through an outage is 240 V, the Yeti drops off your list whatever its capacity.
solar input
At full rating the TITAN refills its 5,017.6 Wh in under an hour and a half (5,017.6 ÷ 4,000); the Yeti needs more than two and a half hours for 7,988 Wh (7,988 ÷ 3,000). When an outage runs for days with sun in between, refill speed sets how full you start each night, and the 450 V ceiling leaves room to wire a big array in long series stringsA3.
TITAN 5000 solar: 40–450 V, 4,000 W maxA3Yeti solar: 3,000 W, reached with Goal Zero's own panels and combinerB28-Hour Blackout (1,645 Wh): TITAN 39% used, Yeti 24%
Why it mattersSolar-backed households planning for week-long outages should rank the TITAN's recharge above the Yeti's bigger tank.
None of the rows asks the question that actually splits these two: whether you need 240 V, or more than 3,600 W at once. The grid flatters the Yeti because it only measures the one thing the Yeti does better.
Scenario peak loads range from 40 W to 400 W, all on 120 VYeti wins 8-Hour Blackout and Van Life Daily; CPAP Overnight and Remote Workday pass on bothTITAN 5000: 7,200 W split-phase outputA1
Why it mattersRead the Yeti's scenario wins as more hours on small loads, not as the better backup for a whole house.
The specific dimensions that decide these two units — everything else is a tie.
Growth Path
Selected because: The TITAN 5000 grows on both fronts the Yeti trails on: 4,000 W of solar against 3,000 W, and packs up to 30,105.6 Wh.
solar input
The engine hands the TITAN 5000 the stronger growth path on solar, and it's right: 4,000 W across 40–450 VA3 against 3,000 W that Goal Zero reaches only with its own panels and combinerB2. The voltage ceiling is the useful half, since 450 V lets a large array run as long series strings rather than a thicket of parallel runs.
Storage climbs in 5,017.6 Wh steps to 30,105.6 WhA7, while the Yeti system tops out at 20 kWh once four Tank PRO 4000s hang off itB1. Both grow. Only one grows into a bank that sits behind a 240 V panel.
Your Life, Your Pick
Selected because: Every row runs 120 V loads of 400 W or less, which makes it a capacity test the Yeti is built to win.
Nothing in this grid draws more than 400 W, and nothing asks for 240 V. So it measures stored energy, and the Yeti's 7,988 Wh wins that fairly: it ends the 8-Hour Blackout at 24% used against the TITAN's 39%, and it clears the 4,685 Wh Van Life day that leaves a stock TITAN 5000 short by 420 Wh after the 85% allowance.
CPAP Overnight and Remote Workday pass on both with most of each battery untouched, and the Yeti's three 100 W USB-C ports make a better laptop setup than the TITAN's single 60 WA9. What the grid never stages is the morning the well pump has to run, which is the morning a 7,200 W split-phase unit was bought for.
Brand Trust
Selected because: Whole-home backup ties you to one maker's panel and app for years, so the ecosystem behind each box matters.
Whole-home backup is a marriage to one maker's hardware, and the two ecosystems differ in kind. EcoFlow sells the TITAN 5000 as a system, with its 240 V Smart Home Panel 10, solar panels and extra packs bundled around itA5, from the deepest catalogue in portable power. Goal Zero's current line is compact, and its previous-generation X series has gone out of stock on its own store.
Service is no tiebreaker. EcoFlow's support swings between fast prepaid-label replacements and long waits, with nothing offered once the warranty is over, and Goal Zero's app carries a recurring record of connection drops and crashes. Since neither side wins on support, the maker that builds the 240 V panel for your house gets the nod.

Scoring these two at a campsite is a category error: neither travels — the TITAN 5000 is 119 lbs and the Yeti PRO 4000 + Tank PRO 4000 (Yeti PRO 8000) 196 lbs, and at those weights they roll off a truck bed if they go anywhere at all. 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.

Yeti PRO 4000 + Tank PRO 4000 (Yeti PRO 8000)
Both survive the night. The Yeti PRO 4000 + Tank PRO 4000 (Yeti PRO 8000) finishes at 24% used with 5,145Wh left — 3.1 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.

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 Yeti PRO 4000 + Tank PRO 4000 (Yeti PRO 8000) 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.

Both power your workstation all day without strain. At these utilization levels the real difference is USB-C for direct laptop charging — 100W on the Yeti PRO 4000 + Tank PRO 4000 (Yeti PRO 8000) against 60W — which beats the inverter for convenience and wastes less energy.

Conclusion
October 4, 2026
Verdict: the TITAN 5000
Buy the TITAN 5000. It doubles the Yeti PRO 8000's continuous output, 7,200 W against 3,600 W, delivers it as the 120/240 V split-phase power the Yeti can't produceA1, takes 4,000 W of solar to the Yeti's 3,000 W, and costs $2,800 less. The Yeti's counter is 7,988 Wh in the box against 5,017.6 Wh, a real edge for long, light outages in a house wired entirely for 120 V. That household is the Yeti's buyer; anyone with a 240 V circuit to keep running belongs with the TITAN.

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 Yeti PRO 4000 + Tank PRO 4000 (Yeti PRO 8000) rates 3.4/5 (4th percentile of 29 Whole-Home / Off-Grid-class units).
How the class ranking is computed →Test Notes & Caveats
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 Yeti PRO 4000 + Tank PRO 4000 (Yeti PRO 8000) (196 lbs) is spread across its boxes — no single lift, but nothing you reposition on a whim. That's a 77 lb difference, and it is paid once — getting the heavier one into position, not every time you move it.
UPS Switchover: ≤15ms vs ≤20ms
Both list a UPS mode, at different rated speeds. The Yeti PRO 4000 + Tank PRO 4000 (Yeti PRO 8000) is rated ≤15ms — fine on paper for routers and most electronics; the fussiest PC power supplies sit right at this line. 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: No Difference
Both units carry the same 5-year warranty, so coverage isn't a tiebreaker here. Worth saying because the per-dollar framing can suggest otherwise: the TITAN 5000 works out at 1.6 years of cover per $1,000 spent against the Yeti PRO 4000 + Tank PRO 4000 (Yeti PRO 8000)'s 0.8, but that spread is the price gap, not the terms.
Yeti PRO 4000 + Tank PRO 4000 (Yeti PRO 8000): Noise Level Not Disclosed
The TITAN 5000 publishes its noise level (39dB); the Yeti PRO 4000 + Tank PRO 4000 (Yeti PRO 8000) doesn't publish one. That isn't evidence the Yeti PRO 4000 + Tank PRO 4000 (Yeti PRO 8000) 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 Yeti PRO 4000 + Tank PRO 4000 (Yeti PRO 8000) before deciding.

Lifetime value
Service lifeyears at one full cycle per day
Lifetime energy delivered
Cost per delivered kWh
│ 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.
Goal Zero
Ecosystem
Focused — a compact current line (6th-gen Yeti and Yeti Pro series), the previous-gen X series now out of stock across every model on Goal Zero's own store (checked 2026-09-13: 200X, 500X, 1000X, 1500X, 3000X, 6000X, some listed only as open-box), so buying one new means finding retailer stock, Sherpa power banks for the under-100Wh tier, plus Alta coolers, Nomad/Ranger solar panels, and vehicle integration kits
Support
US-based company (Salt Lake City, owned by NRG Energy). Historically considered premium support, but 2025-2026 reports describe long wait times, unresponsive email communication, and tickets going unaddressed for weeks. The "premium support justifies premium pricing" argument is weakening.
Community
Small but loyal — strong following in overlanding and preparedness communities. Official community forums were recently shuttered, frustrating long-time users.
App experience
Rated 4.4/5 iOS (~1,200 ratings) but recent reviews skew negative — recurring connectivity issues, crashes, and stability problems.
Unique strength
Pioneer of the portable power market — strongest brand heritage. US-based company with ruggedized, weather-resistant designs (IP ratings vary by model). Integrated "Yeti-Ready" ecosystem with coolers, lights, and vehicle kits.
Worth knowing
Typically the priciest brand per watt-hour — though individual pairings vary, and on some pages the Yeti is the cheaper energy. Support quality has declined from its "premium" standard. Perceived as competitively stagnant vs. faster-innovating Chinese competitors. Reliability reports on newer models are concerning.
Analyst note
EcoFlow and Goal Zero are close competitors. Both have established support channels and growing ecosystems. Compare their specific warranty terms and community size for your peace of mind.

Realistic full solar rechargeat 70% of rated panel output — see methodology
Analyst note
Both expand, but the TITAN 5000's higher solar ceiling (4,000W vs 3,000W) 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 TITAN 5000's record so far is EcoFlow's own rating label and store page, which tell you what the box is rated to do rather than how it behaves in a utility room. They put 7,200 W on a 120/240 V split-phase output at 30 AA1, list an L14-30 among the outletsA2, allow 4,000 W of solar across 40–450 VA3, and describe an AC IN/OUT port that bypasses up to 7,200 W from a split-phase feedA14. Our arithmetic on the 204.8 V pack points to LFP cellsA12.
“7,200 W continuous output with 120/240 V split-phase at 30 A.”
Goal Zero Yeti PRO 4000 + Tank PRO 4000 (Yeti PRO 8000)
Reviewers like the Yeti PRO 4000 that anchors this pairing: they call it a high-powered station built to last and point to a growth path of up to four Tank PRO 4000s for about 20 kWhB1. They also flag that the 3,000 W solar figure needs Goal Zero's own panels and combiner boxB2.
The owner side is less tidyB3. One owner's Yeti 4000 failed to run the first time the power went out and it really mattered, and others say bugs persist that reviewers didn't encounterB3.
“A strong expandable system — you can add up to four Tank PRO 4000 batteries for up to 20 kWh; professional reviewers call it a high-powered, highly reliable power station built to last.”

“Accepts up to 3,000W of solar input, but reaching that ceiling needs Goal Zero's own expensive proprietary panels and combiner box. Note the widely quoted "0% to 100% in under 2 hours" figure describes the standalone PRO 4000; with the Tank attached the system holds roughly twice the energy, so a full refill takes correspondingly longer.”

“Owner reviews are mixed on reliability — one owner's Yeti 4000 didn't work the first time they lost power and really needed it, and some report it's still riddled with bugs, though professional reviewers didn't experience those issues.”

Who Should Buy Which
Buy the TITAN 5000 if you…
- →Your house has a well pump, electric dryer or range on a 240 V breaker, and you want backup that reaches it through EcoFlow's 240 V Smart Home Panel 10A5.
- →You need more than 3,600 W running at once; the TITAN 5000 carries 7,200 W continuousA1.
- →You're building toward a large array and want 4,000 W of solar on a 40–450 V inputA3.
- →A time-of-use-rate home that wants automatic peak shaving: EcoFlow says X-Fusion 2.0 runs the home on stored energy at peak ratesA23, and OASIS 3.0 adds off-peak charging, though the store marks OASIS as a subscription featureA17.
Buy the Yeti PRO 4000 + Tank PRO 4000 (Yeti PRO 8000) if you…
- →Every circuit you back up is 120 V, your outages run long and light, and you want 7,988 Wh without buying an extra pack.
- →You've already invested in Goal Zero panels and its combiner, which the Yeti's 3,000 W solar input calls forB2.
- →Much of your backup load is phones, tablets and laptops, and three 100 W USB-C ports matter more to you than a 240 V circuit.

If neither fits
If you want a power station that leaves the house for campsites, job sites or tailgates, skip both: the TITAN's label keeps it in a utility spaceA10, and the Yeti PRO 8000 is a two-box system built to stay put. A single-box portable with a carry handle is the category you're after.
The Bottom Line
Buy the TITAN 5000. Twice the Yeti PRO 8000's continuous output, a 240 V split-phase circuit the Yeti can't produce, and a quicker solar refill, at $3,199 against $5,999.
The Yeti keeps one honest argument: more watt-hours on day one for a 120 V house that runs light and long. If that isn't your house, get the box that can actually reach your well pump.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
What does the TITAN 5000's L14-30 outlet do that the Yeti PRO 8000 can't?
It delivers 120/240 V split-phase at 30 A, the kind of supply a 240 V circuit is wired for, and EcoFlow pairs the unit with its 240 V Smart Home Panel 10 to feed those circuits. Our record lists no 240 V output on the Yeti PRO 8000, whose 3,600 W inverter runs at 120 V.
Which recharges faster from solar, the TITAN 5000 or the Yeti PRO 8000?
The TITAN 5000. It accepts up to 4,000 W across 40–450 V, enough to refill its 5,017.6 Wh in under an hour and a half at full rating. The Yeti tops out at 3,000 W, and only on Goal Zero's own panels and combiner, so its 7,988 Wh takes more than two and a half hours even in ideal sun.
Where should a TITAN 5000 live in the house?
In a utility space, outside bedrooms and living areas, which is where its label places it under the standard rule for units holding more than 1 kWh. It discharges from −10 °C to 45 °C but charges only from 0 °C to 45 °C, so a garage that drops below freezing in winter will keep it from recharging.
Can the TITAN 5000 pass grid power through to my outlets?
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 to the outlets. The separate wall inlet is 120 V at 15 A, so the split-phase port is the one that matters for a house.
What does the TITAN 5000 add beyond the spec sheet?
EcoFlow lists the TITAN 5000 as UL 9540 certified and tested to UL 9540A, and sells it with a factory pre-wired Smart Home Panel 10 that controls 10 circuits from the app. X-Fusion 2.0 sends solar to the house first and covers peak-rate hours from the battery. Storm Mode charges the battery before severe weather, with switchover under 20 ms.
