Spec deltas
Both of these run 240 V, which removes the question that decides most big-battery comparisons and leaves a better one: how does each one refill? The TITAN 5000 takes 4,000 W of solar across a 40–450 V inputA3. The Anker SOLIX F3800 takes 2,400 W, and that input is the most repeated complaint among its ownersB1B2B13B14.
The TITAN 5000 also carries the bigger stick everywhere else on record: 7,200 W of split-phase output against 6,000 W, and 5,017.6 Wh against 3,840 Wh. The F3800 answers with price. It costs $1,199 less, has eight AC outlets to the TITAN's four, and a 100 W USB-C port to the TITAN's 60 W.
Our call is the TITAN 5000 for a solar-backed home, by a margin a wall-charged buyer could reasonably turn down. If your plan is to plug in between outages and never touch a panel, the F3800 does the 240 V job for less.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
continuous output
Run either one through a 30 A, 240 V inlet and the TITAN can use every amp the cord is rated for, while the F3800 stops 5 A short (30 minus 25). Those 1,200 W are what's left for the rest of the house once the biggest 240 V load is already running.
TITAN 5000: 7,200 W continuous, 120/240 V split-phase at 30 AA1TITAN 5000 outlets: three 120 V 20 A sockets and one L14-30 twist-lock marked 120V/240V 30AA2SOLIX F3800: 6,000 W continuous output; our record lists two 240 V outlets
Why it mattersA household whose running load sits near 6,000 W should pay for the TITAN; one that never gets close gains nothing from this chain.
solar input
On the second day of an outage that's 1,600 W more coming back in every strong-sun hour, through an input with a published 450 V ceilingA3. The F3800's smaller input is also the one its owners fight: one charges from solar only when nothing else will doB1, and others route around it with secondary charge controllersB13.
TITAN 5000 solar: 4,000 W max, 40–450 V MPPTA3F3800 solar: 2,400 W maxTITAN 5000 pack: 5,017.6 Wh; F3800: 3,840 WhF3800 owners consistently report its solar input is restrictive and pushes them toward Anker's own panelsB1B2B13B14
Why it mattersIf panels are your outage plan, this chain is the verdict.
Capacity
Wall-charged, the TITAN's solar lead vanishes and what's left is capacity and 1,200 W of output for $1,199 more. That trade is sound if you need the output and poor if you don't. One F3800 owner also backs off to 600–800 W because the cord runs hot at full rateB3, which trims the F3800's refill edge but doesn't erase the price gap.
TITAN 5000 AC input: 100–120 V, 15 A max, limited to under three hours above 12 AA8One F3800 owner reports a full wall-charge rate of 1,800 W from a 120 V outlet, with a very hot line cordB3TITAN 5000: 5,017.6 Wh; F3800: 3,840 Wh
Why it mattersA wall-recharge, no-panels household is the F3800's buyer, and should keep the difference.
The specific dimensions that decide these two units — everything else is a tie.
Growth Path
Selected because: The TITAN 5000's 4,000 W solar input and 30,105.6 Wh ceiling are its main argument against a cheaper 240 V rival.
solar input
The TITAN 5000 grows to six packs and 30,105.6 WhA7, with 4,000 W of solar feeding it. That is the shape of a whole-home system, and EcoFlow sells it as one, bundled with its 240 V Smart Home Panel 10A5.
The F3800 expands with Anker's own batteries, so neither one is a dead end. The limit worth noticing is the array: a maxed TITAN stack needs about 7.5 hours of full-rated sun to refill from empty (30,105.6 ÷ 4,000), so in practice the panels, not the pack count, set how far this system grows.
Runtime: Will It Power Your Gear?
Selected because: Both run 240 V loads, so runtime shows what the TITAN's extra 1,177.6 Wh and 1,200 W are worth across a real outage.
continuous output
Through the site's 8-hour blackout the TITAN uses 39% of its pack and the F3800 50%, leaving 2,620 Wh against 1,619 Wh. That's 1.6 more nights like it on the TITAN and 98% of one on the F3800.
A bigger inverter doesn't make a battery last longer; it raises the ceiling on what runs at once. The TITAN's 7,200 W lets it carry more of the house together, and its roughly 1,000 Wh of extra usable energy (4,265 against 3,264 after the flat derate) is what lets it keep doing so into the next day.
Brand Trust
Selected because: At this price, how each brand handles a claim matters as much as any spec on the page.
EcoFlow's support record is polarized by its own profile: prepaid-label replacements for some, long waits and refurbished units on new claims for others, and no parts or service once the warranty ends. The profile's advice is to buy through Costco or Amazon for the stronger return net, and on a battery this size it's advice worth taking.
Anker's reputation for no-hassle replacements is trending down in recent reports, with AI-driven support agents and awkward hazmat logistics on heavy units. F3800 owners split: one got fast answers and an advance replacementB9, while another says he was ignored after a large SOLIX purchase, though we couldn't confirm which model he ownedB8.

Weekend Camping
Two nights off-grid with essential comfort
Neither unit
Scoring these two at a campsite is a category error: neither travels — the TITAN 5000 is 119 lbs and the SOLIX F3800 132.3 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.

TITAN 5000
Both survive the night. The TITAN 5000 finishes at 39% used with 2,620Wh left — 1.6 more nights like it. The SOLIX F3800 finishes at 50% with 1,619Wh, 98% of a second night. 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 SOLIX F3800 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.

Neither unit
Neither unit covers this scenario's 4,685Wh: the TITAN 5000 comes up 420Wh short (about 91% covered) (its nameplate 5,018Wh actually clears this — the flat 15% conversion allowance is what tips it under), the SOLIX F3800 1,421Wh (69%).

Conclusion
October 4, 2026
Verdict: the TITAN 5000
Buy the TITAN 5000 if panels are part of your plan. Against the F3800 it adds 1,200 W of continuous output (7,200 W against 6,000 W), 1,177.6 Wh of battery and 1,600 W of solar input through a 40–450 V MPPTA3, while the F3800's solar input is the thing its owners complain about mostB1B2. The F3800 is the right buy for a home that recharges from the wall between outages: it covers 240 V loads too and costs $1,199 less. The call is close, and it turns on whether you will ever hang a panel.
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 SOLIX F3800 rates 4.5/5 (68th percentile of 20 Home Backup-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 SOLIX F3800 (132.3 lbs) is firmly a two-person lift. It goes where you put it and stays there. That's a 13 lb difference.
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 SOLIX F3800 works out at 2.5 years of cover per $1,000 spent against the TITAN 5000's 1.6, but that spread is the price gap, not the terms.
SOLIX F3800: Noise Level Not Disclosed
The TITAN 5000 publishes its noise level (39dB); the SOLIX F3800 doesn't publish one. That isn't evidence the SOLIX F3800 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 SOLIX F3800 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.

Worth knowing
Support quality appears to be declining from its historically excellent level. Firmware updates have removed features without warning. Expansion ecosystem is smaller than EcoFlow's.
Analyst note
EcoFlow positions itself as a mid-to-premium brand with stronger support infrastructure, while Anker competes on value. The question is whether the EcoFlow ecosystem and support premium is worth it for your use case.

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 2,400W) 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
What exists for the TITAN 5000 is EcoFlow's own documentation. The rating label sets 7,200 W of split-phase output at 30 AA1, an L14-30 twist-lock beside three 20 A socketsA2, a 40–450 V solar input good for 4,000 WA3, and a 5,017.6 Wh pack that grows to 30,105.6 Wh across six packsA6A7. By our arithmetic, the label's 204.8 V pack works out to 64 cells in the LFP rangeA12.
“7,200 W continuous output with 120/240 V split-phase at 30 A.”
Anker SOLIX F3800
Solar is the F3800 complaint that keeps coming back. One owner says the input makes anything but Anker's pricier panels hard to use at full capacityB2; another calls it a great unit apart from the limited panel choicesB14; a third notes the workaround is a secondary charge controller, not anything in the boxB13. One poster, whose model we couldn't confirm, reports zero issues and contrasts that with months of EcoFlow firmware troubleB10.
“I have been using the F3800 for a couple weeks now, using only a single 120V outlet into a reliance transfer switch and it runs everything I throw at it including a water pump.”

“no one on Youtube is addressing the solar input problem directly. But People smarter than myself with secondary charge controllers... are able to navigate around the problem.”

“other than the solar input problem having limited panel array choices to max out it's input capability it's a great unit so far.”

Who Should Buy Which
Buy the TITAN 5000 if you…
- →A home with a roof or ground array planned, where the outage plan is to refill from the sun every day the grid stays down.
- →A 240 V household whose running load gets close to 6,000 W and wants the whole 30 A circuit availableA2.
- →Someone building toward a whole-home bank who wants a stated path to 30,105.6 WhA7.
- →A home that already has rooftop solar it wants to keep, or a permit or insurer that asks for UL 9540: the TITAN 5000 is listed as certifiedA15 and can AC couple to compatible existing panelsA19.
Buy the SOLIX F3800 if you…
- →A home that recharges from the wall or a generator between outages and has no plans for panels.
- →A buyer who needs 240 V for a well pump but not 7,200 W, and would rather keep $1,199.
- →Anyone plugging appliances straight into the unit: eight AC outlets and 100 W USB-C beat four outlets and 60 W.
If neither fits
If your outage list is a fridge, a router and some lights, you'd be paying for a 240 V inverter you'll never use; the site's 1,645 Wh blackout night fits inside either pack with room to spare, and a mid-size 120 V portable is the right shelf. And if you like this pack but have nothing on 240 V, EcoFlow's Classic shares the same chassisA13.
The Bottom Line
The TITAN 5000 takes this on recharge. Both units feed 240 V loads, but the TITAN refills a bigger battery faster from the sun, through an input that isn't the F3800's known sore spot, and has 1,200 W more inverter for the evening the whole house wants power.
If the panels are never going up, take the F3800 and keep the money. If they are, the TITAN 5000 is the one built to use them.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the EcoFlow TITAN 5000 better than the Anker SOLIX F3800 for whole-home backup?
For a solar-backed home, yes. It runs 7,200 W to the F3800's 6,000 W, holds 5,017.6 Wh to 3,840 Wh, and takes 4,000 W of solar to 2,400 W. For a home that only recharges from the wall, the F3800 covers 240 V loads for $1,199 less and is the smarter buy.
Do the TITAN 5000 and the F3800 both have 240V outlets?
Yes. The TITAN 5000 has one L14-30 twist-lock rated 120/240 V at 30 A alongside three 120 V 20 A sockets, and our record gives the F3800 two 240 V outlets among its eight AC sockets. Both feed 240 V loads; at 240 V the TITAN's inverter can supply a full 30 A, the F3800's 25 A.
Why is solar charging a sore spot on the Anker F3800?
Owners consistently report that its 2,400 W input is hard to use with panels other than Anker's own, which get expensive for a full setup. The fix the forum settled on is an extra charge controller outside the unit. The TITAN 5000's label lists a 40–450 V, 4,000 W input.
How long does the TITAN 5000 take to charge from a wall outlet?
About three hours at best. Its AC input is 100–120 V at up to 15 A, which is 1,800 W, and 5,017.6 Wh ÷ 1,800 W is 2.8 hours before charging losses. The label also limits draw above 12 A to under three hours, so a full refill from empty sits right at that line.
What does the TITAN 5000 add beyond the spec sheet?
EcoFlow lists the TITAN 5000 as UL 9540 certified and tested to UL 9540A. EcoFlow's X-Fusion 2.0 has solar power the home first and the battery cover peak-rate hours. OASIS 3.0 learns household habits, forecasts solar up to 3 days ahead and charges off-peak, but the store marks it as a subscription feature in the EcoFlow app. The TITAN 5000 can AC couple with compatible existing rooftop solar, which needs the Smart Home Panel 10 and a CT sensor.
