Head-to-head test
Anker SOLIX S5000 vs BLUETTI EP800 + 4×B500
Whether your backup should be able to leave the house: the S5000 is a 97 lb cabinet that rolls to wherever power is needed, while the EP800 stack is nearly four times the energy bolted to your panel for good.

Spec deltas
The BLUETTI EP800 + 4×B500 holds 19,840Wh, nearly four times the S5000's 5,024Wh, and it will never leave the room it's installed in. That's the whole shape of this page. One is a home battery system wired into a subpanel. The other is a 97 lb cabinet on wheels with six AC outlets, including a 240V L14-30R, that you can roll out of the garage and into a truck.
The money runs the other way. The S5000 is $2,500; the BLUETTI stack is $7,999, $5,499 more, before an installer has quoted you anything. Per watt-hour of storage the BLUETTI is a little cheaper. Per kilowatt-hour you'll actually cycle through over the rated life, the S5000 is cheaper, because Anker rates its pack for 6,000 cycles to the BLUETTI's 3,500.
Our pick is the S5000 for anyone whose blackouts end within a day or two and whose biggest loads fit under 4,500W. The EP800 stack is the right buy for a house that wants a week of autonomy and a 9,000W solar array to keep it topped up, and it's the only one of the two with a 10-year warranty.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
Capacity
So the BLUETTI's capacity lead is one you can buy your way out of later, in pieces, while the BLUETTI can never get past 19,840Wh at all. What we can't tell you is what those packs cost: we have no BP5000 price on record, so whether stacking ever beats the BLUETTI on money is still open.
S5000: 5,024Wh, expands with up to five BP5000 packs to 30,144WhA6EP800 + 4×B500: 19,840Wh, no expansionS5000 expansion packs: 5,024Wh eachA6
Why it mattersBuyers who want a small start with a big ceiling should lean S5000; buyers who want all the capacity on day one, installed once, should lean BLUETTI.
solar input
On paper 3,000W refills 5,024Wh in under two hours (5,024 ÷ 3,000 ≈ 1.7), so with a full array the S5000 can keep pace with a modest house day to day. The catch is the garage in January: the pack won't take a charge below 32°FA18, which is exactly where a winter storm leaves it.
8-Hour Blackout: S5000 ends with 2,625Wh, 1.6 more nights; EP800 stack ends with 15,219Wh, 9.3 more nightsSolar input: S5000 3,000W, EP800 stack 9,000WS5000 charges only between 32°F and 104°FA18
Why it mattersCold-climate buyers planning for multi-day outages should weigh the BLUETTI's nine-night buffer above the S5000's lower price.
cost / lifetime kWh
The BLUETTI claws some of that back with time. Its warranty runs 10 years to the S5000's 5, and its lifetime pool of 69,440 kWh is more than double. At one cycle a day the S5000's rating lasts 16.4 years and the BLUETTI's 9.6, both longer than either warranty.
S5000: $0.08 per lifetime kWh over 30,144 kWhEP800 stack: $0.12 per lifetime kWh over 69,440 kWhWarranty: S5000 5 years, EP800 stack 10 years
Why it mattersIf you value years of cover over cents per kWh, the BLUETTI's decade of warranty is the strongest card it holds.
The specific dimensions that decide these two units — everything else is a tie.
Your Life, Your Pick
Selected because: The engine splits them three ways: the S5000 takes the trips, the BLUETTI takes the long nights at home, and neither finishes a van day.
Two of the six scenarios are forfeits, not contests. The BLUETTI is wired to a subpanel, so camping and the tailgate go to the S5000 by default, and it covers both with room left: 2,170Wh spare after the 2,100Wh weekend. Van life is a no for both. The BLUETTI can't go, and the S5000 runs 415Wh short of the 4,685Wh day.
The home rows go to the BLUETTI on endurance, not capability. Both clear the 8-hour blackout and the remote workday; the BLUETTI simply ends the blackout at 10% used where the S5000 ends at 39%. One note on the CPAP row: Anker's label rates the S5000 for non-habitable spaces and keeps a unit this size out of sleeping roomsA7, so it runs the CPAP through a cord from the hallway or garage, not from the nightstand.
Lifetime Value
Selected because: The S5000's 6,000 rated cycles make it the cheaper energy per lifetime kWh, while the BLUETTI is cheaper per watt-hour on the box.
cost / lifetime kWh
Energy you'll actually use is the S5000's best number: $0.08 a lifetime kWh against $0.12. It gets there on cycle life, 6,000 to 3,500, which outweighs the BLUETTI's lower cost per watt-hour on the shelf.
The honest counterweight is the warranty. Ten years on the BLUETTI, five on the S5000. A cycle rating is a promise about the cells; a warranty is a promise about who pays when the inverter quits in year seven.
Growth Path
Selected because: Only the S5000 can grow, and five BP5000 packs take it to 30,144Wh, past the BLUETTI's fixed 19,840Wh.
solar input
This is the rare pair where expansion is a real argument for the smaller unit. The S5000 takes up to five BP5000 packs through a 400V DC portA6. Three put it past the BLUETTI's sealed capacity, and five reach 30,144Wh.
The BLUETTI's four B500s are its ceiling. Its compensation is solar: 9,000W of input against 3,000W, which matters more than raw capacity once an outage outlasts the battery.
Portability & Form Factor
Selected because: 97 lb on wheels against 606.6 lb installed at the panel decides every scenario that leaves the house.
weight
Ninety-seven pounds on wheels, with a pull rod and a foot step for tipping it backA10A11, is a one-person roll across a garage floor and a two-person lift into a truck bed. 606.6 lb of installed BLUETTI is a delivery and an electrician.
That's also why the S5000 can serve a house without becoming part of it. Its L14-30R carries 4,500W of 240V split-phaseA3, the same twist-lock a portable generator uses, so an electrician-fitted inlet lets it feed chosen circuits and roll away afterward.

SCN-01 · 2 nights · needs 2,100Wh
Weekend Camping
Two nights off-grid with essential comfort
SOLIX S5000
The EP800 + 4×B500 is installed at the electrical panel — it backs up the building and doesn't leave it, so this scenario belongs to the SOLIX S5000 by default — and it earns it, covering the 2,100Wh with 2,170Wh to spare. Capacity was never the EP800 + 4×B500's problem here; getting to a campsite was.

8-Hour Blackout
Keep the essentials running through a night without power
EP800 + 4×B500
Both survive the night. The EP800 + 4×B500 finishes at 10% used with 15,219Wh left — 9.3 more nights like it. The SOLIX S5000 finishes at 39% with 2,625Wh, 1.6 more nights like it. If your outages tend to run past one evening, that difference is the whole argument between them.

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 + 4×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 9, 2026
Verdict: the Anker SOLIX S5000
Take the S5000. It costs $2,500 against $7,999, puts a 240V L14-30R and a TT-30R on its front panel, covers our 8-hour blackout load with 2,625Wh left, and its 6,000 rated cycles work out to $0.08 per lifetime kWh against the BLUETTI's $0.12. The EP800 + 4×B500 is the better machine for one household: the one whose outages last days and whose loads pass 4,500W at the same moment, where 19,840Wh, 7,600W and a 10-year warranty earn the gap. Confidence is held back because nobody outside Anker has tested the S5000 yet.

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, SOLIX S5000 rates 4.6/5 (74th percentile of 20 Home Backup-class units), and EP800 + 4×B500 rates 3.9/5 (36th percentile of 29 Whole-Home / Off-Grid-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 SOLIX S5000 (97 lbs) is manageable solo but heavier than a large checked suitcase. The EP800 + 4×B500 (606.6 lbs) is a wall-installed system — its weight matters to the installer on day one, then never again.
EP800 + 4×B500: Fixed Capacity
The EP800 + 4×B500 is sealed at 19,840Wh — a complete unit, and already larger than the SOLIX S5000's 5,024Wh. By contrast the SOLIX S5000 can add expansion batteries, but that only pulls ahead if you'd grow past 19,840Wh.
UPS Switchover: ≤10ms vs ≤20ms
Both list a UPS mode, at different rated speeds. The SOLIX S5000 is rated ≤10ms — quick enough on paper that desktop PCs and routers should ride through, treating that as the rating it is. The EP800 + 4×B500 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: 10 Years vs 5
The EP800 + 4×B500 is covered for 10 years against the SOLIX S5000's 5 years. The cheaper SOLIX S5000 does buy more warranty per dollar (2 years per $1,000 against 1.3), but that is a statement about price, not about coverage — if a fault appears in year 6, only one of these is still covered. An underrated factor if you're keeping this unit for years.
Battery Lifespan in Real Years
The SOLIX S5000 is rated for 6,000 cycles vs 3,500. In real life: at daily use, that's 16.4 vs 9.6 years. At weekend use (twice a week), it's 58 vs 34 years. One caution reading years across different sizes: a cycle is 5,024Wh on the SOLIX S5000 and 19,840Wh on the EP800 + 4×B500, so count lifetime energy — roughly 30,144 kWh against 69,440 kWh over the rated life. After hitting the cycle limit, the battery doesn't die — it drops to ~80% of original capacity, which is still very usable.
EP800 + 4×B500: Noise Level Not Disclosed
The SOLIX S5000 publishes its noise level (30dB); the EP800 + 4×B500 doesn't publish one. That isn't evidence the EP800 + 4×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 SOLIX S5000's 30dB as the only published number on the table — a spec-sheet figure, not a measurement — and look for hands-on reports of the EP800 + 4×B500 before deciding.

Analyst note
The SOLIX S5000 wins on both sticker price and long-term value. At $0.08/kWh over its lifetime, it's meaningfully cheaper to own. Clear value winner. One caution on the lifespan row: the SOLIX S5000 takes longer to reach its cycle rating, but a cycle moves a different amount of energy on each unit — the EP800 + 4×B500 still delivers more over its shorter horizon (69,440 vs 30,144 kWh). Years measure wear, not usefulness.
Brand trust
Anker
Ecosystem
7-8 SOLIX portable power stations across C-series (compact) and F-series (flagship), plus the X1 home energy system
Support
US-based support. Historically known for incredible no-hassle replacements, but recent reports describe AI-driven support agents giving generic responses and complex return logistics for heavy units (hazmat shipping). The Anker brand reputation is still strong, but SOLIX-specific support quality is trending down.
Community
Moderate — active Reddit (r/Anker, r/AnkerSOLIXCommunity) and growing. Benefits from Anker's massive consumer electronics brand awareness.
App experience
Rated 4.5/5 iOS (~1,100 ratings) · 4.3/5 Android
Unique strength
Anker's name from consumer electronics, and on this model a pack rated for 6,000 cycles to 80%.
Worth knowing
SOLIX support has drawn complaints about generic automated replies and awkward returns on heavy units, so keep the box and the paperwork.
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
Support is the least consistent in the category and runs largely by email; buying direct from BLUETTI tends to go better than buying through a third party.
Analyst note
Neither brand's support record is a reason to pick it. The brand fact that actually separates this pair is the warranty on the specific model: 10 years on the EP800 stack, 5 on the S5000.
Growth path
SOLIX S5000
EXPANDABLESupports Anker expansion batteries, so you can add capacity later without replacing the base unit — useful if your needs may climb past 5,024Wh.
Accepts up to 3,000W of solar. Enough for a serious multi-panel array.
Adequate ports for most setups, but heavy users may want a power strip.
Expansion batteries are Anker-specific. You're investing in the Anker ecosystem.
EP800 + 4×B500
FIXED CAPACITYFixed at 19,840Wh — a sealed, complete system rather than a starting point. There's no expansion port, so that figure is the ceiling: check it against your longest unplugged stretch before you buy.
Accepts up to 9,000W of solar. Enough for a serious multi-panel array.
Limited ports. You'll likely need a power strip or splitter.
Realistic full solar rechargeat 70% of rated panel output — see methodology
Analyst note
Don't read the SOLIX S5000's expandability as a straight win here: it starts at 5,024Wh, below the EP800 + 4×B500's 19,840Wh, so a first expansion battery largely buys back capacity the EP800 + 4×B500 already includes. It only pulls ahead if you'd grow past 19,840Wh — short of that, the EP800 + 4×B500's larger fixed capacity is the simpler value.

No owner report covers this exact four-battery stack. What exists describes the EP800 platform in a smaller configuration, mostly from people weighing a purchase on a DIY solar forum rather than living with one, and the researcher couldn't confirm every post is about the EP800 itself, so read it for characterB0. The recurring theme is price: forum posters call it a good product their wallets won't allowB1B2.
The worries are about the long run. One poster flagged BLUETTI's support reputation, and another pointed out that if the inverter fails, the batteries can't run on anything elseB3B4. On the positive side, one owner of a sibling EP760 + B500 install reports flawless switchover and build qualityB8, and one forum member liked that the modular system can move house with youB6.
“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 SOLIX S5000 if you…
- →The homeowner who wants 240V in the garage for a storm, and the same cabinet at the campsite in July.
- →Anyone who'd rather start at 5,024Wh and add BP5000 packs as the budget allows than buy 19,840Wh up front.
- →RV owners: the TT-30R takes a 30A shore cord directly, at up to 3,600W.
Buy the EP800 + 4×B500 if you…
- →The house that needs days, not hours: 19,840Wh carries our 8-hour blackout load for more than nine further nights.
- →Owners with a large roof array, since 9,000W of solar input refills the bank in a few strong hours.
- →Anyone who'd rather pay once for a 10-year warranty and stop thinking about the battery.
If neither fits
If you only want a camping battery, close this tab: both are overkill, and a small station you can lift with one hand covers a weekend. And if you already own a generator and see a couple of short outages a year, a transfer switch and the generator you have is the cheaper answer.
The Bottom Line
Buy the S5000. At $2,500 against $7,999 it covers the overnight outage with plenty left, delivers each lifetime kilowatt-hour for less, and can still leave the house. If your outages are measured in days and your panel pulls more than 4,500W at once, the BLUETTI's 19,840Wh and 10-year warranty are worth the gap. Otherwise, roll the Anker into the garage and keep the difference.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Can the Anker SOLIX S5000 run a house during a power outage?
Selected circuits, yes. Its L14-30R delivers 4,500W at 240V split-phase, but feeding a panel needs an electrician-fitted inlet and transfer switch. It covers our 8-hour blackout load with 2,625Wh left over.
Is the BLUETTI EP800 with four B500 batteries portable?
No. It weighs 606.6 lb as a system and is hardwired to a subpanel with no outlets on the box, so it stays where it's installed. Its modular parts can move house with you, which is a different thing from taking it camping.
Which costs less to own, the S5000 or the EP800 + 4×B500?
The S5000, per unit of energy delivered: $0.08 per lifetime kWh against $0.12, because it's rated for 6,000 cycles to the BLUETTI's 3,500. The BLUETTI is cheaper per watt-hour of storage and carries twice the warranty, 10 years to 5.
Can I expand the S5000 to match the BLUETTI's capacity?
Yes. It takes up to five BP5000 packs of 5,024Wh each; three get you to 20,096Wh, past the BLUETTI's 19,840Wh, and five reach 30,144Wh. We have no pack price on record, so cost that out before you plan around it.
