Home backup used to mean a noisy gas generator or a wall-mounted battery that cost five figures installed. A newer middle tier has changed that: large lithium iron phosphate (LFP) batteries that start around 3.5 to 5 kWh, expand to 20 to 30 kWh, and cost a fraction of a traditional install. The Jackery HomePower 3600 Plus, the Anker SOLIX F3800 Plus, and the EcoFlow TITAN Plus (officially the TITAN 5000 Plus, launched this month) are three of the most talked-about options. They look similar on a spec sheet, but they connect to a home very differently, and that changes which one is right for you.
⚡ Quick Answer: The Jackery is the cheapest per kWh (about $477 at street price) and the lightest. The Anker is the strongest single-box 240V option for the money (about $651 per kWh). The EcoFlow TITAN Plus has the most capacity, output, and solar input, and is the most "whole-home ready," but it costs the most per kWh (from $737) and is brand new.
How Each One Works for Home Backup
- Jackery HomePower 3600 Plus (appliance-level backup): Plug your refrigerator, sump pump, router, CPAP, or space heater straight into its outlets, including a 30A RV-style TT-30 outlet. It switches over to battery in under 10 milliseconds, so it doubles as a UPS for a home office. Jackery also sells a manual transfer switch for feeding selected home circuits. A single unit is 120V only, so 240V loads like a well pump or central air need a second unit.
- Anker SOLIX F3800 Plus (portable meets whole-home): It outputs true 120V/240V split-phase power with a 240V L14-30R outlet, so it can run larger 240V loads. Anker sells home backup kits, and it can also be tied into a home's circuits through a transfer switch or inlet. It accepts solar, wall power, and a generator, which makes it flexible for multi-day outages.
- EcoFlow TITAN 5000 Plus (installed whole-home battery): This one is designed to live in a garage or utility room. It ships with an optional pre-wired Smart Home Panel 10 that manages up to 10 circuits and switches your home to battery automatically. It is UL 9540 certified and EcoFlow says it can start a 3-ton central air conditioner without a soft starter.
A safety note that applies to all three: connecting any battery to a home's electrical panel, whether through a transfer switch, inlet, or smart panel, should be done by a licensed electrician in line with local code. Also note that a grid-tied rooftop solar system normally shuts down during an outage for safety, so existing rooftop panels will not charge a backup battery during a blackout unless the system is set up for it.
Side-by-Side Comparison
Here is how the three stack up. The best value in each row is highlighted in green. On a phone, each row becomes its own card so nothing gets squeezed.
| Feature | Jackery HomePower 3600 Plus | Anker SOLIX F3800 Plus | EcoFlow TITAN 5000 Plus |
|---|---|---|---|
| Capacity & Lifespan | |||

| Retail (list) price | $2,799 | $4,799 | $3,699 standalone; $4,799 with Smart Home Panel 10 |
| Current street price | About $1,709 | About $2,499 (range $2,400 to $2,600) | From $3,699 (launch pricing) |
| Price per kWh (at list price) | $781 per kWh | $1,250 per kWh | $737 per kWh |

| Lifetime cost per kWh delivered | About $0.08 | About $0.22 | Can't be calculated (cycles unpublished) |
How we calculated it: price per kWh is price divided by base capacity (3.584, 3.84, and 5.0176 kWh). Lifetime cost is street price divided by capacity times rated cycles. Jackery rates its 6,000 cycles to 70% capacity and Anker rates its 3,000 cycles to 80%, so that row is not a perfect apples-to-apples comparison. Prices are approximate as of October 25, 2026 from retailer listings and price trackers, and they change often. Jackery in particular has been listed anywhere from about $1,619 to $2,799 depending on the retailer.
The Three Contenders in Detail
Jackery HomePower 3600 Plus
Pros
- Lowest cost per kWh of the three at street price
- Longest rated cycle life (6,000 cycles) and lowest lifetime cost
- Lightest at 77 lb, with wheels and a telescoping handle
- Plug-and-play with no installation needed
- Sub-10 ms UPS switchover for computers and medical devices
Cons
- 120V only from a single unit; 240V requires a second unit
- Lowest output (3,600 W) and surge (7,200 W) of the three
- Solar input capped at 1,000 W, so solar recharging is slow
- Retail prices vary widely between sellers
The HomePower 3600 Plus is the value and portability pick. It packs 3,584 Wh of LFP storage and a 3,600 W inverter into a 77 lb unit that one person can roll across a garage. At roughly $1,709, it works out to about $477 per kWh, the lowest of the three, and with a 6,000-cycle rating its lifetime cost per kWh delivered is under ten cents. That makes it especially attractive for people who want to cover essentials like a refrigerator, freezer, internet, lights, and a CPAP without hiring an electrician.
The trade-offs show up when loads get bigger. A single unit is 120V, so a well pump, electric dryer, or central air conditioner needs a second unit and the double kit, which brings output to 7,200 W at 120V/240V. Solar charging is also modest: the two DC inputs top out at 1,000 W, which takes about four hours for a full charge in ideal sun, though wall charging at up to 1,800 W refills it in around 2.5 hours. If you need more runtime, add-on Battery Pack 3600 Plus modules (listed around $1,349 to $1,499 each) can take a single unit to about 21.5 kWh.
Anker SOLIX F3800 Plus
Pros
- 6,000 W of true 120V/240V split-phase power in one unit
- 9,000 W surge handles motor startup loads
- 3,200 W solar input through two 165V inputs
- Expands to 26.9 kWh (53.8 kWh with two units)
- Generator input and bypass for long outages
Cons
- Fewest rated cycles (3,000+ to 80%), so higher lifetime cost
- Heaviest of the three at about 137 lb
- $4,799 list price is rarely paid; real prices run $2,400 to $2,600
- Whole-home tie-in needs a transfer switch or kit (extra cost)
The F3800 Plus sits between a portable power station and a true installed home battery. It offers 3,840 Wh of LFP storage, 6,000 W of continuous output at 120V/240V, and a 9,000 W surge rating, which is enough to run a well pump, a small 240V air conditioner, or a full set of kitchen appliances at once. Its dual 165V solar inputs accept up to 3,200 W, so a good array can refill it in under two hours of strong sun, and adding a generator can cut that to about an hour. At around $2,499 it costs about $651 per kWh.
Where it gives ground is longevity and weight. Anker rates the battery at 3,000+ cycles to 80% capacity, about half of Jackery's cycle count, which pushes its lifetime cost per kWh to roughly $0.22 versus $0.08. At about 137 lb it is also the heaviest of the group, and the optional BP3800 expansion batteries add cost quickly. It makes the most sense for homeowners who want 240V power and big solar charging without paying for a fully installed system, and who are comfortable adding a transfer switch or home backup kit.
EcoFlow TITAN 5000 Plus
Pros
- Largest base capacity (5 kWh) and expansion ceiling (30 kWh)
- Highest output: 7.2 kW, or 10 kW with solar
- 8 kW of solar input across two 4 kW inputs
- UL 9540 certified, with an optional pre-wired Smart Home Panel 10
- Quiet: below 39 dB at 5,000 W, per EcoFlow
Cons
- Highest price per kWh ($737, or about $956 with the panel bundle)
- Cycle rating not published; no long-term field record yet
- Indoor use only (IP20, dry location) and not portable
- Some energy-management scheduling is a subscription feature
EcoFlow announced the TITAN series on October 13, 2026, with the 5000 Plus as the flagship above the TITAN 5000 and TITAN 5000 Classic. The Plus pairs a 5,017.6 Wh LFP battery with 7.2 kW of 120V/240V output, rising to 10 kW when solar and battery work together, and it accepts up to 8 kW of solar. Extra 5 kWh batteries bring a system to roughly 30 kWh. EcoFlow says it can start a 3-ton central air conditioner without a soft starter, which is a task that trips up most of the portable-style competition.
It also behaves more like a traditional home battery: it is UL 9540 certified and tested to UL 9540A, uses a 200V architecture, and can be bought with a factory pre-wired Smart Home Panel 10 that gives app control of 10 circuits. The cost of that polish is the highest price per kWh here, and EcoFlow has not published a cycle rating, only a "up to 10 years" use rating alongside the 5-year warranty. Because it launched less than two weeks ago, there is no real-world durability record yet, and reports peg a panel-plus-installation setup in the neighborhood of $7,000. It is the best fit for homes with central air, large solar arrays, and a desire for automatic switchover.
