For backing up the circuits a home can't do without, the best battery here is the EcoFlow DELTA Pro 3: 4,096Wh with 120/240V output, 4,000W continuous and an 8,000W surge, a 10 ms switchover, and room to grow to 12kWh per unit, and EcoFlow lists it as UL 9540 certificated. For the biggest loads, look at the 7,200W EcoFlow DELTA Pro Ultra or Jackery Explorer 5000 Plus. If you only need the fridge, router and lights, a 2 kWh station like the Anker SOLIX C2000 Gen 2 is enough, with no panel work.
No single battery here runs a whole house for long: the average US residential customer bought about 29.6 kWh of electricity a day in 2022, per the EIA, and the biggest single battery here holds 6.1 kWh. So the real questions are which circuits you back up, how the system connects to your panel (always a licensed electrician's job), and which safety listing your inspector expects. Every spec below comes from the makers' pages and manuals, checked on November 1, 2026. We haven't lab-tested these systems.
What each system can back up
| System | Output | Continuous / surge | Capacity, and expansion per unit | Max solar input | UPS switchover |
|---|---|---|---|---|---|
| EcoFlow DELTA Pro 3 | 120/240V | 4,000W / 8,000W | 4,096Wh, to 12kWh | 2,600W (30-150V and 11-60V inputs) | 10 ms |
| Anker SOLIX F3800 Plus | 120/240V | 6,000W / not published | 3,840Wh, plus up to 6 x 3.84kWh | 3,200W (2 x 11-165V) | 20 ms (3 left outlets; 120V wall input, no generator) |
| Jackery Explorer 5000 Plus | 120/240V | 7,200W / 14,400W | 5,040Wh, to 30kWh with up to 5 Battery Packs | 4,000W (135-450V and 8mm inputs) | 0 ms online; under 20 ms backup |
| EcoFlow DELTA Pro Ultra | 120/240V | 7,200W / 10.8kW for 10 s | 6,144Wh, to 30kWh | 5,600W (80-450V and 30-150V inputs) | 0 ms online; under 20 ms backup |
| BLUETTI Apex 300 | 120V, or 120/240V on its NEMA 14-50R | 3,840W / not published | 2,764.8Wh, plus up to 6 x B300K | 2,400W (2 x 12-60V) | 0 ms or 20 ms by outlet |
| Anker SOLIX C2000 Gen 2 | 120V | 2,400W / 4,000W peak | 2,048Wh, to 4,096Wh | 800W (11-60V) | 10 ms |
Whole home or essential circuits?
- 29.6 kWhAverage US residential customer's daily electricity use (EIA: 10,791 kWh in 2022 ÷ 365)
- 6.1 kWhLargest single battery here (EcoFlow DELTA Pro Ultra)
- 1.0-1.75 kWhDaily use of a typical ENERGY STAR full-size fridge
The arithmetic decides the strategy. One DELTA Pro 3 (4,096Wh) holds about 14% of an average home's day, and one DELTA Pro Ultra battery about 21%, before losses. Backing up the whole house through a long outage means stacking batteries, adding solar, or both. Backing up essential circuits (fridge, freezer, lights, router, a few outlets, maybe a well pump) is what most systems here are sized for.

To size your own: list the circuits you can't do without, add their running watts to check against the continuous rating, add the biggest motor's starting surge (BLUETTI's manuals warn that motors and compressors may start at 2 to 4 times their rated power), then multiply average watts by the hours you want for capacity. Our refrigerator watts guide shows the method for the biggest essential load.
Best overall: EcoFlow DELTA Pro 3
The DELTA Pro 3 is the most balanced system here. It holds 4,096Wh of LFP (4,000 cycles to 80%) and delivers 4,000W continuous at 120/240V, 6,000W with X-Boost, with an 8,000W surge for motor starts, per EcoFlow's spec table. Its outlets include an L14-30R and a NEMA 6-20R for 240V loads, a TT-30R and four NEMA 5-20R. Solar arrives on two inputs: a high-voltage one (30-150V, 1,600W) and a low-voltage one (11-60V, 1,000W). It switches over in 10 ms.
EcoFlow
EcoFlow DELTA Pro 3 Portable Power Station (4,096Wh, 120V/240V)
A 4,096Wh LFP home-backup power station with 4,000W of 120V/240V output (8,000W surge), 2,600W of dual solar input and expansion to 12kWh per unit, listed by EcoFlow as UL 9540 certificated.
Comes in 7 versions: see which to buy
- 4096 Wh capacity
- 4000W AC out
- LiFePO4
It grows in clear steps: two DELTA Pro 3 Extra Batteries take one unit to 12kWh, and three units on EcoFlow's Smart Home Panel 2 reach 36kWh. EcoFlow's product title says "UL9540 Certificated", the energy storage standard; ask your electrician to confirm the listing in UL's Product iQ database before the inspection. It weighs 113.5 lb on wheels and carries a 5-year warranty. EcoFlow says it also accepts the older DELTA Pro Smart Extra Battery on current firmware, but it can't be paired with a DELTA Pro Ultra.
Best for solar and a generator: Anker SOLIX F3800 Plus
Anker's F3800 Plus is built for big solar and a backup generator. Its two solar inputs each take 11-165V and up to 1,600W (3,200W in total), and its HPP and generator port passes up to 6,000W in and out at 120V/240V, from a 240V pure-sine generator or a 240V wall outlet, per Anker's spec table. Output is 6,000W at 120/240V from an L14-30R, with six NEMA 5-20R outlets and a TT-30R.
Anker SOLIX
Anker SOLIX F3800 Plus Portable Power Station (3,840Wh, 120V/240V)
A 3,840Wh LFP home-backup power station on wheels with 6,000W of 120V/240V output, up to 3,200W of solar input, a 6,000W generator/HPP bypass port and expansion with up to six BP3800 batteries.
Comes in 7 versions: see which to buy
- 3840 Wh capacity
- 6000W AC out
- LiFePO4
It holds 3,840Wh of LFP and takes up to six BP3800 batteries (3.84kWh each), about 26.9kWh per unit by our arithmetic; Anker quotes 53.8kWh and 12kW for a two-unit system. The trade-offs: Anker notes the 240V output can't be used while the unit is charging from a 120V outlet, the UPS switchover is 20 ms and applies only to the three left outlets when it's plugged into a 120V wall outlet with no generator connected, Anker publishes no surge figure in these specs, the cycle rating is 3,000+, and at 136.7 lb it rolls rather than carries. Anker's copy calls the expansion batteries plug-and-play, but connecting the system to your house through Anker's Home Power Panel or a transfer switch is electrician work. Check the name on any deal: Anker's own comparison shows the original F3800 (no "Plus") without the generator bypass and with 2,400W of solar input instead of 3,200W.
Most surge: Jackery Explorer 5000 Plus
Jackery's Explorer 5000 Plus has the biggest surge rating here: 14,400W, with 7,200W continuous at 120/240V from its 30A 120/240V output, per Jackery. Its online UPS mode switches in 0 ms (backup UPS is under 20 ms), and its solar input combines a 135-450V high-voltage port with two 8mm low-voltage ports (up to 1,200W) for 4,000W in total. It holds 5,040Wh of LiFePO4 and expands with Battery Pack 5000 Plus; Jackery says one unit takes up to five Battery Packs for 30kWh; two units with 10 packs reach 60kWh. Its US manual says it connects to the Jackery Smart Transfer Switch "to power your entire house."
Jackery
Jackery Explorer 5000 Plus Portable Power Station (5,040Wh, 120V/240V)
A 5,040Wh LiFePO4 home-backup power station with 7,200W of 120V/240V output (14,400W surge), up to 4,000W of solar input, 0 ms online UPS and expansion with Battery Pack 5000 Plus.
Comes in 5 versions: see which to buy
- 5040 Wh capacity
- 7200W AC out
- LiFePO4
Know the fine print. Each of the four 120V 20A outlets is rated 2,400W, and each pair shares 3,600W, per the US manual. The cell rating is 4,000 cycles to 70%, and it weighs about 134.5 lb. The warranty is 5 years.
Best whole-home system: EcoFlow DELTA Pro Ultra
The DELTA Pro Ultra is a modular system: a 7,200W inverter at 120/240V (10.8kW surge for 10 seconds) on top of 6,144Wh LFP batteries, up to five per inverter for 30kWh, and up to 90kWh and 21.6kW with three inverters on EcoFlow's Smart Home Panel 2, per EcoFlow. Its high-voltage solar input takes 80-450V and up to 4,000W, plus a 30-150V input for 1,600W more, and its online-UPS outlets switch in 0 ms. EcoFlow says one unit can run a 3-ton central air conditioner as long as its locked-rotor amps (LRA) are within 120A, and lists the system as "UL 9540 Certificated".
EcoFlow
EcoFlow DELTA Pro Ultra Whole-Home Backup (Inverter + 6kWh Battery)
A modular whole-home backup system pairing a 7,200W 120V/240V inverter with a 6,144Wh LFP battery, expandable to 30kWh per inverter, with up to 5,600W of solar input; listed by EcoFlow as UL 9540 certificated.
Comes in 7 versions: see which to buy
- 6144 Wh capacity
- 7200W AC out
- LiFePO4
The cost of that capability is weight and complexity: the inverter is 70 lb and each battery 111.8 lb, it doesn't accept third-party inverters or DELTA Pro 3 batteries, and the cell rating is 3,500 cycles to 80%. EcoFlow notes that connecting it to rooftop solar means NEC rapid-shutdown rules apply, and that a qualified electrician or installer must be consulted first. EcoFlow's newer DELTA Pro Ultra X is a different product with different specs, so check the name on any deal.
Longest-rated battery life: BLUETTI Apex 300
BLUETTI rates the Apex 300's LiFePO4 cells for 6,000+ cycles to 80% of original capacity, the highest rating here. One unit holds 2,764.8Wh and delivers 3,840W in total, and its voltage selector switches output between 120V and 240V: on battery, the NEMA 14-50R then gives 120V/240V at up to 16A, per the US manual. The UPS switchover is 0 ms on its two left outlets when set to 240V and fed from the grid through the 15A input, and 20 ms otherwise. Solar input is 2,400W over two 12-60V inputs, and each unit takes up to six B300K batteries; BLUETTI says two or three linked units with up to 18 batteries reach 11.52kW and 58kWh.
BLUETTI
BLUETTI Apex 300 Home Battery Backup (2,764.8Wh)
A 2,764.8Wh LiFePO4 home-backup unit with 3,840W of AC output, a NEMA 14-50R and TT-30R, 2,400W of solar input and expansion with up to six B300K batteries per unit.
Comes in 7 versions: see which to buy
- 2765 Wh capacity
- 3840W AC out
- LiFePO4
The caveats: there are no USB or 12V ports without BLUETTI's separate Hub D1, its certification line says "UL" without naming a standard, and BLUETTI's manual says the UPS isn't meant for data servers or workstations.
Best for essentials only: Anker SOLIX C2000 Gen 2
If your goal is the fridge, the router, lights and phones, you may not need a panel connection at all. The C2000 Gen 2 holds 2,048Wh of LiFePO4, delivers 2,400W at 120V (4,000W peak), switches over in 10 ms and doubles to 4,096Wh with one BP2000 battery. Plug the essentials straight in: a median ENERGY STAR full-size fridge runs roughly 20 to 32 hours on it by our estimate, and nothing touches your home's wiring. It's 41.7 lb, takes 800W of solar, and has a 5-year warranty. Our best portable power stations guide covers more stations in this size class.

How it connects to your house
There are three ways to use a home battery, and only the first needs no electrician:
- Plug appliances into the unit. Run a fridge, router and lamps from its outlets. Simple, but nothing on your home's circuits is backed up.
- A transfer switch or inlet box. A licensed electrician wires selected circuits to a switch that you, or the system, flip to battery power. Jackery names its Smart Transfer Switch, a manual transfer switch or an inlet box for the Explorer 5000 Plus, and EcoFlow lists an inlet box or a manual transfer switch for the DELTA Pro 3 as well as its smart panel.
- The maker's smart panel. EcoFlow names its Smart Home Panel 2 for the DELTA Pro 3 and DELTA Pro Ultra, and Anker its Home Power Panel for the F3800 Plus. These are electrician installs too.

Safety listings: UL 9540 vs UL 2743
The listing matters most when a battery stops being portable. UL Solutions says UL 2743 covers portable power packs "intended to be used when normal grid power is not available, such as in camping or emergency situations," while UL 9540 is the standard for energy storage systems, and that the model installation codes require UL 9540 listing for a stationary battery system in a home. A pack certified only to UL 2743 and wired in as a home battery, it says, "has not been safety certified to the correct standard" for that use.
The makers say different things, so read the wording:
- Yes: EcoFlow DELTA Pro 3 and DELTA Pro Ultra: product titles say "UL 9540 Certificated" (EcoFlow's wording; confirm in UL Product iQ)
- Partly: BLUETTI Apex 300: certification line lists "UL" without naming a standard
- Partly: Anker SOLIX F3800 Plus, Jackery Explorer 5000 Plus and Anker SOLIX C2000 Gen 2: no UL standard named in the specs we read
UL's summary of the residential code (IRC R328 and NFPA 855) also sets where a stationary battery system can go: generally no more than 20 kWh per unit, 40 kWh in total in utility closets, basements and storage spaces, and 80 kWh in garages, on exterior walls or outdoors, unless a UL 9540A fire-test report supports more; and never in sleeping rooms or in closets or spaces that open directly into them. Your electrician and inspector apply the local version.
How we choose
We picked current 120/240V home backup systems from four major brands, plus one 2 kWh station for essentials, using only the makers' spec tables, product pages and user manuals. Where a maker's figures seem to conflict, we settle them in its manual: Jackery's 2,400W and 3,600W outlet ratings turn out to be per outlet and per pair. Safety listings are quoted in the maker's own words and checked against UL Solutions' explanation of the standards. We checked each model against the US Consumer Product Safety Commission's recall database on November 1, 2026 and found no recall. We haven't lab-tested these systems, and we never give wiring instructions: connecting any of them to a house is a licensed electrician's job. We earn a commission on qualifying purchases through our links; it never decides a pick (disclosure).
Verdict
The EcoFlow DELTA Pro 3 is the home battery to start with: 240V, a stated UL 9540 claim, a 10 ms switchover and clear expansion to 12kWh. Choose the Anker SOLIX F3800 Plus for big solar arrays and a 240V generator, the Jackery Explorer 5000 Plus for the largest motor starts, and the EcoFlow DELTA Pro Ultra if you're building a true whole-home system. The BLUETTI Apex 300 has the longest-rated cells, and the Anker SOLIX C2000 Gen 2 covers the essentials without touching your panel.
Frequently asked questions
Can a portable power station power a whole house?
Only for a few hours on one battery. The average US residential customer bought about 29.6 kWh of electricity a day in 2022 (EIA's 10,791 kWh a year), and the largest single battery here holds 6.1 kWh. Expandable systems close the gap: EcoFlow's DELTA Pro Ultra takes up to 30kWh per inverter. Most people back up essential circuits instead, through a transfer switch or the maker's smart panel installed by a licensed electrician.
How many watts does a house use?
On average, about 1.2kW. EIA puts the average US residential customer at 10,791 kWh in 2022, about 899 kWh a month, which is roughly 1.23kW around the clock. Peaks are far higher when an air conditioner, well pump or oven starts, so a backup system is sized for the loads you choose to run together, not the average. Your electric bill shows your own monthly kWh.
Do I need an electrician to install home battery backup?
To connect it to your home's wiring, yes. A transfer switch, inlet or smart panel that feeds your circuits is work for a licensed electrician, with a permit where your town requires one. Plugging a fridge or lamp straight into the unit's outlets needs no installation. Ask the electrician which safety listing your inspector expects for a stationary battery.
What's the difference between UL 9540 and UL 2743?
UL 2743 is the standard for portable power packs, meant for use when grid power isn't available, such as camping or emergencies. UL 9540 is the standard for energy storage systems. UL Solutions says the model installation codes require UL 9540 listing for a stationary battery system in a home, and that a pack certified only to UL 2743 isn't certified to the correct standard for that use.
Can a home battery run a well pump or central air conditioner?
Some can, if the motor is within the system's 240V output and surge ratings. EcoFlow says one DELTA Pro Ultra can run a 3-ton central AC whose locked-rotor amps are within 120A, and Anker says the F3800 Plus powers fridges to central AC. Check the appliance's nameplate voltage and amps, remember that motors may start at 2 to 4 times their rated power, and have your electrician confirm the circuit.
