EcoFlow TITAN 5000 Plus: big output, a 5 kWh battery, and the number EcoFlow hasn't published

EcoFlow launched the TITAN series on October 13 — three whole-home backup systems and a new electrical panel that does not replace your main one.

Updated October 15: prices landed, about two and a half weeks ahead of the November 3 date in the launch materials. The TITAN 5000 Plus starts at $3,699, the TITAN 5000 at $3,199, and the Classic at $2,499.

Updated October 21: EcoFlow published bundle pricing, and subtracting across the bundles gives up the two numbers that were missing — the panel and the expansion battery. "What a stacked system actually costs", further down, runs the comparison this post was waiting to run.

I run an EcoFlow DELTA Pro Ultra and an Ultra X behind a Smart Home Panel 3, on a time-of-use rate with a demand charge, so this launch lands directly on top of what I use every day.

Short version: the panel is what changes the economics, and at these prices this line is probably the best backup value in the category. The 5 kWh battery means the advertised price is the start of a quote rather than the end of one. And the 10 circuits limit what stays on during an outage, not what the battery can offset on your bill — a distinction worth getting right before you order.

The three models

$500 separates the 5000 from the Plus, and that $500 buys a second 4 kW MPPT — doubling solar input from 4 kW to 8 kW — plus the PV boost rated to 10 kW. If you are putting any meaningful array on this, the Plus is the one; 4 kW of solar input is a low ceiling for a system meant to carry a house. If you are buying it as a backup box with no solar plans, the 5000 does the same 7.2 kW for less.

These are "from" prices on the base unit. The Smart Home Panel 10 is extra, and so is every battery past the first — EcoFlow still does not sell either as a line item, though the October 21 bundle prices give both away, which I work through further down. The launch materials put a complete system with panel and installation in the $7,000 range, which is consistent with a $3,699 base, but that is a national talking point rather than a quote.

Worth noticing what this does to the entry comparison. At $3,699 for 5 kWh, the Plus works out to about $740 per kWh of nameplate storage. A DELTA Pro Ultra base runs roughly $650 per kWh at the midpoint of its range, for a slightly larger 6.144 kWh pack. The TITAN is the cheaper box and the more expensive storage — which only matters because storage is the thing you have to keep buying.

All three are listed as expanding in 5 kWh steps to a 30 kWh ceiling, which is a base unit plus five TITAN Battery modules. Cells are LFP, the warranty is five years, and the system transfers to battery in under 20 milliseconds during an outage.

Notice what is identical across the whole line: 5 kWh. The models differ on power and solar, not on storage.

The 5 kWh base unit is the thing to understand first

A 7.2 kW output rating tells you what you can switch on at once. It tells you nothing about how long it stays on. Those are different questions, and the marketing for every battery on the market leans on the first one.

To be fair to EcoFlow, getting 7.2 kW out of 5 kWh is the actual engineering achievement here. The launch credits an "industry-first 40160 tabless 2C LFP cell," and a 2C continuous rate is aggressive for home LFP storage — it is why this pack can hit those power numbers at all. EcoFlow's own framing is that it delivers "heavy-duty performance without overpaying for unnecessary storage."

That argument is sound for backup and breaks down for bill savings, and the split is worth seeing in numbers.

Take 5 kWh, hold back about 15% to protect the cells, and lose a bit more to conversion and standby draw, and you get roughly 3.7 kWh actually delivered to the house. That lands like this:

For outage coverage that is a short evening, not a storm.

For bill savings the arithmetic is different, because what you need to cover is a window. Most time-of-use rates put their expensive hours in a block three to four hours long, and covering it takes your average load multiplied by those hours:

• A 3-hour window at 1.2 kW takes the entire base unit, with nothing spare.
• A 3-hour window at 2 kW needs about 6 kWh delivered — two batteries.
• A 4-hour window at 2.5 kW needs about 10 kWh delivered — three batteries.

So the base unit by itself does not cover one peak window for most homes, and the entry price is not the price of a system that lowers a bill. You need two to four batteries for the cases above, and the per-battery price is exactly the number EcoFlow has not released. Everything about whether this is a good deal is sitting behind that one figure.

At the 30 kWh ceiling you are looking at about 22 kWh delivered. That lands almost exactly where a DELTA Pro Ultra tops out, at roughly 30 kWh — so against the entry EcoFlow the ceilings match, and the open question is the cost of getting there. Against the Ultra X, which takes eight expansion batteries for roughly 61 kWh, the TITAN runs out of room at half the distance.

The Smart Home Panel 10 is the actual news

The cell is the engineering news. The panel is the news that changes what an install costs.

EcoFlow describes the Smart Home Panel 10 as backing up 10 selected circuits at 50 A without replacing your main electric panel, with breakers pre-assembled and cables pre-wired before it ships — which they claim cuts field labor by up to 80%.

That is worth taking seriously, because the panel is where this category gets expensive. My Smart Home Panel 3 became my main service panel, all 32 circuits moved into it, and that is a large job with a permit and an inspection behind it. A pre-wired 10-circuit subpanel sitting next to your existing main is a fundamentally smaller piece of work. If the install pricing lands anywhere near the $7,000 all-in figure in the launch materials, it undercuts the main-panel route by a wide margin.

The 50 A figure is a power ceiling, and a generous one — at 240V that is about 12 kW, more than any of these inverters can deliver anyway. The constraint is not amps. It is the number 10.

What the 10 circuits do and don't limit

This is the part I got wrong on my first read of the spec sheet, and it is worth being precise about, because the two operating modes behave differently.

On the grid, the 10 circuits are not the limit. EcoFlow's own wording: "Working with the grid through your main panel, TITAN can power across your home — beyond the circuits on a subpanel." The SHP10 carries a CT sensor for self-consumption and no-export control, which is the standard arrangement for a grid-interactive battery — it discharges into the main panel and modulates output so nothing flows back to the utility. For peak shaving, a load on a circuit you never put in the panel still gets offset.

In an outage, the 10 circuits are exactly the limit. When the grid drops, only what is wired into the SHP10 is islanded and running. The rest of the house is dark. That is the real trade for skipping the main-panel replacement, and it is a backup decision rather than a billing one.

So what caps bill savings on a time-of-use rate is not the circuit list. It is two other numbers.

Inverter output. 7.2 kW is the most the battery can supply at any instant. A house pulling more than that during the expensive window takes the difference from the grid. On a rate with a demand charge that matters out of proportion: mine bills $10.90 per kW on the single highest 15-minute on-peak interval of the month — one interval, not total usage — so a single heavy morning above the inverter's ceiling sets a charge for the entire cycle.

Your existing panel can cap that output further. A grid-interactive battery backfeeding the main panel does it through a breaker, and assuming the usual load-side connection, the NEC's 120% rule (705.12) limits that breaker to 120% of the busbar rating minus the main. On a 200 A panel that allows about 40 A, or 9.6 kW — comfortably above the inverter. On a 125 A panel it is nearer 25 A, about 6 kW; on a 100 A panel about 20 A, or 4.8 kW, which clips on-grid output below the 7.2 kW on the box. Electricians have routes around it, a supply-side tap among them, but if your service is small this is the first thing to ask about — and it is the concrete version of "depends on the panel you already have."

Battery capacity, which is the one that actually binds. A base unit delivers about 3.7 kWh, and a three-hour window at 2 kW needs 6. When the pack empties partway through, the rest of the window bills at the full on-peak rate, and the worst 15 minutes of that grid draw sets the demand charge regardless. The protection is capacity, and capacity is the thing the 5 kWh base does not have.

EcoFlow agrees, if you read the fine print. The savings claim on the TITAN series page — up to $4,000 a year, payback in as little as three years — is footnoted to "a 15kWh TITAN 5000 Plus system paired with Smart Home Panel 10, 8kW solar, approximately 16.5kWh of daily household electricity use, optimized solar self-consumption, and SDG&E TOU-DR2 rates in San Diego, CA."

Fifteen kilowatt-hours is three batteries. Eight kilowatts is the Plus's entire solar input. Their own payback math does not run on the unit in the headline price — and now that the bundles are out, that exact configuration can be priced: $8,699 with the panel, against the $3,699 on the headline.

What is genuinely better here

Solar input, with a caveat. The Plus takes 8 kW across two MPPTs, which is a real step up from the 5.6 kW ceiling on the base DELTA Pro Ultra — the unit most people price first, and a ceiling that genuinely limits how much array a battery can use.

Against the existing line it looks smaller. An Ultra X on its own accepts 10 kW, and more than one battery system can sit behind a single Smart Home Panel 3 — I have a Pro Ultra and an Ultra X both wired into mine, which is four PV inputs and a 15.6 kW ceiling between them. Whether the Smart Home Panel 10 accepts a second TITAN the same way is not something the launch materials address, and that decides whether 8 kW is the platform's ceiling or only one unit's.

Existing rooftop solar. EcoFlow lists the TITAN as AC-coupling to compatible third-party rooftop solar, using the 240V Smart Home Panel 10 and a CT sensor. That matters for a group I usually have bad news for: homeowners who already have grid-tied panels that go dark the moment the grid does. Most of what I write about is battery-coupled solar, where the panels wire into the battery directly. A supported path for an array that already exists is a different and useful option. I would want to see the compatibility list before counting on it for any specific inverter.

One limit comes with it: EcoFlow lists the grid connection as no-export, and the CT sensor exists to enforce that. There is no net-metering path, so surplus solar goes into the battery or gets curtailed — and for Dominion customers in South Carolina that specifically means no Solar Choice export credits. It also makes the size of the pack, again, the thing that decides how much of your own generation you keep.

Install friction. Factory pre-wiring and skipping the main panel swap both attack the same cost. The 80% labor reduction is EcoFlow's number rather than a measurement, but the direction is clearly right.

One warning on the Classic

The TITAN 5000 Classic is the cheapest headline in the lineup and the easiest mistake to make. It is 120V only.

That means no 240V loads at all: no central air conditioning, no electric water heater, no well pump, no electric dryer, no electric range.

It does get a panel — EcoFlow lists a 120V Smart Home Panel 10 that the Classic pairs with, so you still get automatic transfer across selected circuits. Those circuits just cannot include anything on 240V, which in most houses is the list of things you actually worried about losing. If "whole-home" is what you are shopping for, the Classic is not the model, whatever the price says.

The Anker in the room

Anker launched the SOLIX S5000 on October 9, four days before TITAN. Also 5 kWh. Also expandable to 30 kWh. Launch price $2,499.99 — a dollar under the TITAN Classic, with an MSRP of $3,599.99 after the introductory window. If you are shopping this category this month you will see both, and the specs line up closely enough to blur together.

They are not the same kind of product. Anker's own announcement calls the S5000 a "portable power station" — 97 pounds on wheels with a telescoping handle — and names no smart panel, transfer switch or Power Dock anywhere in it. The outage feature is a 10-millisecond UPS switchover, which is an outlet, not a house. Time-of-use scheduling, peak shaving and grid charging are not mentioned at all.

So it is a different purchase, and for some people the better one. Running a fridge, some lights and a few plug loads through a storm, at $2,499.99 with UL 9540 certification and 6,000 cycles behind it, the S5000 is a strong box and cheaper than wiring anything into your house. It also has more output headroom than the TITAN Classic — 4,500 W against 4,000 W, with 240V on both.

For shifting load off a peak window, it does not have the pieces. No panel integration means no automatic whole-home transfer; no scheduling means no peak shaving. The Smart Home Panel 10 is precisely the thing the S5000 does not have, and that panel is most of why the TITAN is interesting.

What a stacked system actually costs

EcoFlow has still not put a price on the Smart Home Panel 10 or an expansion battery as line items. On October 21 they published bundle pricing, and the bundles give both away:

Subtract across the rows. The Smart Home Panel 10 is $1,000 to $1,100 — $4,199 less $3,199 one way, $4,799 less $3,699 the other. Each 5 kWh expansion battery is $1,900 to $2,000: $6,799 less $4,799, then $8,699 less $6,799.

That puts an expansion battery at roughly $390 per kWh. A DELTA Pro Ultra module runs about $334 per kWh for a 6.144 kWh pack. Expanding a TITAN costs about 17% more per kilowatt-hour than expanding the system I run — which is what the 5 kWh base unit led me to expect.

What I did not expect is that the complete system still comes out cheaper:

The batteries are dearer and the system is cheaper, and the panel is the entire reason. A Smart Home Panel 3 runs about $3,000 against the Smart Home Panel 10's $1,050. That $1,950 head start is worth more than the pricier batteries take back — each rung of about 6 kWh returns roughly $340 of it — so the TITAN stays ahead all the way to the top of its 30 kWh range, but only just: at full stack it is about $485 per kWh against $495.

Which is the trade stated in money. The panel is cheaper because it does not replace your main service panel, and what you give up for that is 10 backed-up circuits instead of a whole house. Install should favor it for the same reason, though nobody has published those numbers.

Two things stop this being a quote. My DELTA Pro Ultra figures are mid-2026 retail ranges while the TITAN's are launch pricing, and the early-bird 5% is in neither column.

What we still don't know

• Standalone prices. The panel and the battery are still only available inside bundles. The figures above are derived by subtraction, and they are consistent across two independent pairs of rows, but EcoFlow has not confirmed either as a sticker price.
• Installed cost. The $7,000 all-in figure is encouraging, and it is a national talking point rather than a quote for your home — install pricing turns on local labor and the condition of the panel you already have.
• Measured round-trip efficiency. Spec sheets and what a pack actually delivers are different numbers. Logging my own turned up a 5 kWh gap against the usable figure I had been publishing, and I corrected the site rather than the measurement.

Why it isn't in our system picker yet

The analyzer sizes three systems — two EcoFlow, one Anker — and the TITAN is not among them, which needs explaining given everything above.

Two reasons, neither about the product. The hardware links on this site run through one authorized multi-brand dealer, and they do not carry the TITAN yet, so there is nothing to point you at. And the installed-cost estimate behind those quotes assumes the smart panel replaces your main service panel, because that is what a Smart Home Panel 3 does. The Smart Home Panel 10 does not, so running a TITAN through that estimate would bill it for work it does not need and make it look worse than it is.

We earn a commission on the systems in the picker and nothing on the TITAN. That has not changed what this post says about it.

If you're reserving now

These are pre-orders — EcoFlow ships when stock arrives. The listed terms are a $50 deposit for 5% off, two free 220 W panels, and $300 off Smart Home Panel 10 installation, with the balance payable on financing at up to 12 months at 0% APR between November 3 and December 31. The reservation window closes November 2 at 11:59 PM PST.

That is a different decision from buying. Fifty dollars holds a discount and the two free panels are real hardware. You can now total a configuration, which you could not a week ago — so the reason to hold has shifted from "the numbers do not exist" to the ordinary one of whether you want this system at these prices.

Read the deposit's refund terms before you place it. Whether this is optionality or a commitment turns entirely on that detail, and it is not something I can check on your behalf.

Where I land

The Smart Home Panel 10 is the most interesting thing EcoFlow has shipped in a while, because the main-panel replacement is the single biggest cost and scheduling obstacle in whole-home backup, and this skips it. For someone who wants the lights and the fridge to stay on through a storm, a $2,499 to $3,699 base plus a pre-wired subpanel is likely the better value in the category — and that case does not depend on the battery price I am still waiting on, because one pack covers a short outage.

For a bill-reduction build, the number I was waiting on has arrived, and it says something more interesting than I expected. Storage costs about 17% more per kilowatt-hour here, and the system still totals less than the equivalent Pro Ultra build because the panel is a third of the price. If you want a battery to carry you through a peak window, you are buying three of them either way — EcoFlow's own payback math assumes exactly that — and on this pricing the TITAN is the cheaper route to it, provided the 10 circuits cover what you need backed up.

What is left is the part money cannot answer. Running the TITAN through the same engine behind the analyzer — time-of-use windows, the demand charge, the efficiency figures I measured rather than the ones on the box — needs a measured round-trip number from the new 2C cell, not a spec-sheet one. I got a 5 kWh surprise the last time I logged my own packs against what I had published. That comparison waits on hardware, not on pricing.

If you are sizing a system right now, work out the capacity you need first and let that decide the hardware. The capacity requirement does not change because a new model launched.
