Whole-home battery backups range from integrated inverter-and-battery systems to portable power stations, and my best overall pick is the EcoFlow DELTA Pro Ultra 12kWh for buyers seeking substantial capacity in a system designed to scale. The ECO-WORTHY 30,720Wh system with a 10kW inverter stands out for large energy reserves, while the Jackery Explorer 5000 Plus offers a more portable, all-in-one approach. The key tradeoff is between home integration and capacity on one side, and portability and simpler setup on the other. Battery capacity alone does not tell you which appliances a system can run; inverter output and installation requirements matter just as much. Read on for my full comparison and guidance on matching a backup to your home.

Key Takeaways
- Integrated capacity separates the strongest whole-home candidates. The EcoFlow DELTA Pro Ultra and ECO-WORTHY 30,720Wh system pair sizable storage with inverter hardware, while several portable picks start with less capacity.
- Battery-only bundles need closer system checks. ECO-WORTHY’s Powermega two-pack supplies substantial storage, but buyers must verify compatible inverter, controls, and installation components before treating it as a complete backup.
- 10kW inverter output appears across several ECO-WORTHY systems. That output can support more simultaneous household loads than smaller portable units, but it does not determine how long those loads will run.
- Portable power stations trade installation flexibility for capacity and integration limits. Jackery and Anker options can suit targeted backup needs, but buyers should check home-circuit connection and expansion details.
- Solar bundles are not automatically whole-home solutions. The Jackery HomePower 3600 Plus includes two panels, yet panel output, sunlight, and battery capacity all affect how much energy is available during an extended outage.

ECO-WORTHY Powermega 48V 314Ah LiFePO4 Battery, 2-Pack
For buyers building a substantial home backup bank, this two-battery set supplies 32.14 kWh of stated storage before adding an inverter or other system components. That makes it a stronger fit for extended outages than the Jackery Explorer 5000 Plus by itself, though the Jackery is a more self-contained option for people who prefer a portable power station. Here, the appeal is system-building flexibility: each battery has a 200A active-balancing BMS, several inverter communication interfaces, and support for expansion up to 15 units. UL 1973 certification and built-in aerosol fire suppression add safety features relevant to a large stationary installation. The tradeoff is logistics and setup: these are large batteries shipped on a pallet, and the delivery address must accommodate truck delivery. I’d choose this for a planned, expandable battery bank, not for quick plug-and-play backup.
Pros:- Two batteries provide 32.14 kWh of stated combined capacity.
- UL 1973 certification and built-in aerosol fire suppression.
- Wi-Fi, Bluetooth, RS485, CAN, and RS232 support monitoring and system integration.
- Supports expansion to as many as 15 units and includes a 10-year warranty.
Cons:- Batteries are large and heavy, making placement and installation harder.
- Pallet delivery requires an address that can accept a truck shipment.
- Batteries alone do not provide an inverter or a complete home backup system.
Best for: Homeowners and off-grid system builders who already have, or plan to install, a compatible inverter and need substantial expandable storage.
Not ideal for: Buyers seeking an all-in-one portable backup or a simple appliance-ready kit; these batteries require compatible system components and pallet-truck delivery.
- Chemistry:LiFePO4
- Nominal voltage:51.2V
- Capacity per battery:314Ah
- Energy per battery:16.07kWh
- Pack quantity:2
- BMS:200A with active cell balancing

Our verdict“Choose this set for high-capacity, expandable stationary storage if you can handle the delivery and pair it with a compatible inverter.”
ECO-WORTHY 48V Home Backup Power, 30,720 Wh Battery, Liber 10KP 10kW Inverter
This kit pairs 30.72 kWh of battery storage with a 10kW pure sine wave inverter, so it arrives closer to a whole-home off-grid system than the ECO-WORTHY Powermega battery set, which supplies storage but not an inverter. Its six batteries and included server rack create a modular foundation, while the inverter’s 20kW surge rating helps accommodate brief startup demands from appliances. The system can also grow by paralleling equipment, with stated expansion up to 60kW AC output. App monitoring and CAN/RS485 communication give owners useful visibility into system operation. The cost of that capability is a more involved installation: multiple batteries and components need space, setup, and coordination, and the product data notes separate shipping. Its listed output is 120V; 240V support requires parallel units, so buyers should plan the configuration around their home’s loads.
Pros:- Includes six 100Ah batteries, a server rack, accessories, and a 10kW inverter.
- 30.72kWh of stated battery capacity supports longer backup than smaller portable stations.
- 20kW surge output can help handle short appliance startup loads.
- Supports expansion and app monitoring, with UL1973 and UL1741 certifications listed.
Cons:- Multiple batteries and system components make installation and setup more involved.
- Large footprint and heavy equipment require suitable space and handling.
- 240V output requires parallel units, and components may ship separately.
Best for: Homeowners building a large off-grid or whole-home backup installation who want batteries, rack, and inverter in one modular kit.
Not ideal for: Buyers who need a compact, ready-to-use portable station or want 240V output without adding and configuring parallel units.
- Battery configuration:6 × 51.2V 100Ah LiFePO4 batteries
- Total battery capacity:30,720Wh
- Continuous inverter output:10,000W

Our verdict“Pick this kit when you want a high-capacity inverter-and-battery foundation and have the space and expertise for a modular installation.”
Jackery Explorer 5000 Plus Portable Power Station, 5040Wh, 7200W
The Explorer 5000 Plus is the most portable-system-oriented choice here: it combines a 5,040Wh LiFePO4 battery with 7,200W rated output and 120V/240V support in one power station. That is simpler to deploy than the ECO-WORTHY 10kW kits, which offer more built-in storage but require a larger, more involved installation. For a house, the Jackery’s main limitation is not output but stored energy: 5.04kWh can support selected loads, yet it is a smaller starting bank than either ECO-WORTHY system. Expansion to 60kWh and up to 4,000W of solar input give owners a path to longer backup, though those capabilities depend on adding equipment. At 134.5 pounds, it is portable in the product-category sense, not easy to carry. Solar panels are optional, and the five-year warranty is shorter than the Powermega batteries’ stated warranty.
Pros:- Provides 7,200W rated output with both 120V and 240V support.
- LiFePO4 battery offers 5,040Wh of built-in storage.
- Expandable capacity is listed up to 60kWh.
- Accepts up to 4,000W of solar input.
Cons:- Its 5,040Wh starting capacity is well below the ECO-WORTHY high-capacity kits.
- At 134.5 pounds, moving it is difficult for one person.
- Solar panels are optional, and the warranty is five years.
Best for: Households that want a movable 120V/240V backup station for selected circuits, RV use, or a system they may expand over time.
Not ideal for: Buyers who need extensive whole-home runtime immediately or expect a lightweight station they can frequently carry by hand.
- Battery chemistry:LiFePO4
- Battery capacity:5,040Wh
- Surge output:14,400W
- Voltage:120V/240V
- Expandable capacity:Up to 60kWh
- Maximum solar input:4,000W
- Weight:134.5 pounds
- Warranty:5 years
Our verdict“Choose the Jackery for a movable 240V power station with an expansion path, but not if you need a large battery bank out of the box.”
ECO-WORTHY 48V Home Backup Power System with 10.24kWh Battery and 10kW Inverter
This kit takes a different route from the six-battery ECO-WORTHY system: it starts with 10.24kWh of storage and a 10kW inverter, leaving room to expand rather than supplying a very large battery bank at the outset. That lower initial storage makes it a more measured starting point for a household sizing backup around priority loads, while the dual MPPT controllers support solar charging without a separate controller. The listed inverter can provide 120V, but 240V requires parallel inverters; buyers with well pumps, central air, or other 240V loads should account for that added hardware. By comparison, the Jackery Explorer 5000 Plus includes 120V/240V output in a portable unit, but has less built-in storage and a different installation model. This ECO-WORTHY kit suits planned stationary expansion, though separate shipping and system configuration add work.
Pros:- Combines two 100Ah LiFePO4 batteries with a 10kW inverter.
- Dual MPPT controllers and a battery charger are included.
- Supports expansion to 32 batteries and up to six parallel inverters.
- Offers Bluetooth, Wi-Fi, CAN, and RS485 communications.
Cons:- 240V output requires additional inverters connected in parallel.
- Items ship separately, complicating delivery and installation planning.
- Its 10.24kWh starting capacity is lower than the six-battery ECO-WORTHY kit.
Best for: Homeowners who want a stationary 10kW inverter and solar-ready setup, with the option to add battery capacity or inverters as needs grow.
Not ideal for: Buyers who need 240V output from the included single-inverter setup or want a portable, ready-to-use power station.
- Battery chemistry:LiFePO4
- Battery configuration:2 × 51.2V 100Ah
- Total battery capacity:10,240Wh
- Inverter output:10,000W
- Peak output:20,000W
- Output voltage:120V; 120V/240V with parallel inverters
- Maximum parallel inverters:6
- Maximum parallel batteries:32
- Safety standards:UL1973 and UL1741 testing; meets California Energy Commission standards
Our verdict“Choose this kit for a solar-ready, expandable stationary system if 120V is enough initially or you plan to add inverters for 240V loads.”
Anker SOLIX F3800 Portable Power Station, 3,840Wh
The SOLIX F3800 prioritizes portable, dual-voltage power over the large built-in storage of the ECO-WORTHY home kits. Its 3.84kWh battery and 6kW continuous output can run selected major appliances, while 120V/240V support and NEMA 14-50 and L14-30 connections make it a more natural fit for RVs and compatible transfer setups. Direct EV charging is another distinctive use, but it does not turn this single unit into a long-duration whole-home battery bank: its stated runtime at full load is one hour. Additional battery packs or a smart generator can extend backup, although that means building the system beyond the base station. Compared with the Jackery Explorer 5000 Plus, the Anker has less built-in capacity and lower continuous output, but offers explicit EV/RV ports and app-based power management.
Pros:- Provides 6,000W continuous output and 120V/240V power.
- NEMA 14-50 and L14-30 ports support listed EV and RV uses.
- Battery capacity can be expanded with additional packs.
- Wi-Fi and Bluetooth app control support remote monitoring.
Cons:- The 3.84kWh base capacity limits whole-home runtime.
- Its stated full-load runtime is one hour.
- The unit is large and heavy, and expanded storage requires additional equipment.
Best for: RV owners and homeowners seeking a movable 120V/240V source for selected circuits, with direct EV/RV connections and an expansion option.
Not ideal for: Households needing long whole-home runtime from one unit or buyers who want a stationary system with a large battery bank included.
- Battery capacity:3.84kWh
- Continuous output:6,000W
- Peak output:10,200W
- Voltage:120V/240V
- Solar input:2.4kW
- EV charging port:NEMA 14-50, 6kW
- RV compatibility ports:NEMA 14-50 and L14-30
- Warranty:5 years
- Lifespan claim:10 years
Our verdict“Pick the F3800 for portable 240V, RV, or selected-circuit backup, but choose a larger stationary kit for longer whole-home coverage.”
Jackery HomePower 3600 Plus Portable Power Station with Two 200W Solar Panels
I’d choose the Jackery HomePower 3600 Plus for buyers who want a sizable battery they can move, rather than a fixed whole-home installation. Its 3,584Wh capacity and 3,600W output can support selected household loads, while parallel operation adds 240V output and up to 7,200W—useful for broader coverage when paired units are configured for it. The included solar panels and four charging methods offer more off-grid flexibility than a basic backup station. Compared with the EcoFlow DELTA Pro Ultra, this Jackery is much lighter and easier to reposition, but starts with less capacity and output. Expansion is a strength, though reaching whole-home scale means adding equipment; at 77.2 pounds, moving it still takes effort. I’d also allow for the power station and panels to arrive separately.
Pros:- 3,584Wh capacity and 3,600W output provide a strong starting point for backup loads.
- Parallel operation supports 120V and 240V output and up to 7,200W.
- AC, solar, hybrid, and generator charging suit varied backup and off-grid setups.
- Wheels and a telescopic handle make relocation easier than with the heavier EcoFlow DELTA Pro Ultra.
Cons:- One unit’s capacity is limited for extended whole-home backup.
- At 77.2 pounds, it is portable but not easy to carry.
- The power station and included solar panels may ship separately.
Best for: Households seeking movable backup for selected circuits that may expand their system over time, with solar charging as an option.
Not ideal for: Buyers who need substantial whole-home runtime from a ready-to-install system or cannot lift and reposition a 77.2-pound unit.
- Battery capacity:3,584Wh
- Battery type:LFP
- AC output:3,600W
- Parallel output:Up to 7,200W
- Voltage:120V; 240V in parallel

- Charging options:Hybrid AC+DC, AC, solar, and gas generator
- Cycle life:6,000 cycles
- Included solar panels:Two 200W panels
Our verdict“Choose this Jackery for movable, expandable backup for selected household loads, not as a high-capacity whole-home system out of the box.”
EcoFlow DELTA Pro Ultra 12kWh Power Station with Extra Battery
The EcoFlow DELTA Pro Ultra is the stronger fit when backup needs include 240V appliances and room to grow beyond a portable power station. Its 7,200W 120V/240V output can handle heavier household loads than the Jackery HomePower 3600 Plus, while app-based circuit management gives owners more control over what receives power. The listed capacity is 6,144Wh per battery, and expansion to 90kWh offers a path to longer backup periods; the included extra battery increases the starting reserve. Solar, wall, EV charging equipment, and generator inputs add flexibility, and the 0ms UPS transfer is useful for connected equipment that cannot tolerate a break in power. The tradeoffs are scale and setup: at 293.6 pounds, this is not a unit to move casually, and its inverter and battery ship separately. I’d favor the ECO-WORTHY 30kWh system for a more fixed, high-capacity setup.
Pros:- 7,200W output supports demanding household appliances on 120V and 240V circuits.
- Capacity can expand up to 90kWh for longer backup needs.
- 0ms UPS transfer time helps keep connected equipment powered through an outage.
- Charging options include solar, wall outlets, EV charging equipment, and generators.
Cons:- The 293.6-pound system is difficult to move and calls for a planned installation location.
- Inverter and battery ship in separate packages.
- Its expandable design may require additional equipment to reach the capacity needed for extended whole-home backup.
Best for: Homeowners who need 120V/240V support, high output, circuit management, and a system that can expand for longer backup.
Not ideal for: Buyers who want a lightweight portable station, a simple one-piece delivery, or substantial capacity without planning a larger system.
- Output power:7,200W
- Voltage:120V/240V
- Battery capacity:6,144Wh per battery
- Expandable capacity:Up to 90kWh
- Maximum system output:21.6kW with three inverters
- Charging methods:EV charging equipment, solar, wall outlets, or outdoor generators
- UPS transfer time:0ms
- Weight:293.6 pounds
Our verdict“Choose the DELTA Pro Ultra if you want high-output 120V/240V backup with extensive expansion, and can accommodate its weight and system setup.”
ECO-WORTHY 48V 314Ah LiFePO4 Battery System with 10kW Hybrid Inverter
For buyers prioritizing stored energy over portability, I’d put the ECO-WORTHY 48V system ahead of the smaller starting configurations in this lineup. Its two batteries provide 30kWh+ of usable energy, paired with a 10kW hybrid inverter and 120V single-phase or 240V split-phase output. That combination suits a home backup or off-grid installation designed around household circuits, rather than a station that can be wheeled between rooms. The active-balancing BMS, fire suppression, and Bluetooth/WiFi monitoring add useful layers of protection and system visibility. Compared with the EcoFlow DELTA Pro Ultra, this ECO-WORTHY offers more stated usable energy in its listed configuration, but lacks the EcoFlow’s stated 0ms UPS transfer and broad charging list. It also calls for a fixed setup, and shipments may arrive at different times; the inverter exterior version is selected at random.
Pros:- Over 30kWh of usable energy supports longer backup than the listed starting capacity of the Jackery HomePower 3600 Plus.
- 10kW hybrid inverter supports 120V single-phase and 240V split-phase output.
- Bluetooth, WiFi, RS485, CAN, and RS232 provide several monitoring and communication options.
- Active-balancing BMS, circuit breaker, and built-in aerosol fire suppression add protection features.
Cons:- A fixed battery-and-inverter system is less portable than the Jackery HomePower 3600 Plus.
- Batteries and inverter may arrive in separate shipments at different times.
- The inverter exterior version is selected at random.
Best for: Homeowners or off-grid users planning a fixed backup installation who need over 30kWh of usable storage and 240V split-phase output.
Not ideal for: Buyers who need a portable power station, a quick plug-and-play setup, or certainty about the inverter’s exterior version.
- Battery configuration:2 × 48V 314Ah LiFePO4 batteries
- System usable energy:30kWh+
- Inverter capacity:10,000W
- Peak output power:20,000W
- Output voltage:120V AC; supports 240V split-phase
- Battery cycle life:9,000+ cycles at 80% DoD
- Communication:RS485, CAN, RS232, Bluetooth, and WiFi
- Safety features:Active-balancing BMS, circuit breaker, aerosol fire suppression, and buzzer alarm
- Energy specification:UL1973
Our verdict“Choose this ECO-WORTHY system for a fixed installation where high usable capacity and 240V support matter more than portability or rapid setup.”
How We Picked
I ranked these products around the practical demands of whole-home backup: usable battery capacity, inverter output, system completeness, expansion potential, and the work needed to connect backup power to household circuits. A high-capacity battery is not a complete solution if the inverter, transfer equipment, or compatible controls are missing, so I distinguish integrated systems from battery components and portable stations.
The ranking favors products that pair meaningful storage with strong output and a clear path to home use. That puts the EcoFlow DELTA Pro Ultra first as a substantial integrated option, with the 30,720Wh ECO-WORTHY package close behind for buyers who prioritize stored energy. Portable models rank lower for whole-home coverage, though they can be better fits for simpler, targeted backup. I also weighed drawbacks: installation complexity, component compatibility, portability limits, and the risk of overestimating what a system can run.
Factors to Consider When Choosing Whole Home Battery Backups
Before choosing a model, I would work backward from the circuits and outage duration you need to cover. A whole-home label does not guarantee that every appliance can run at once, and system sizing depends on both power and energy—not just the battery’s headline capacity.
Separate running power from stored energy
Inverter output sets how much power the system can supply at a given moment, while battery capacity sets how long it can keep supplying it. List the appliances you expect to run together, including equipment with a startup surge such as a refrigerator or pump. A system with ample kilowatt-hours can still struggle if its inverter cannot handle the combined load. Conversely, a powerful inverter paired with a small battery may run several devices but only for a limited time. Check both continuous and surge ratings against your actual equipment, rather than assuming one headline number describes overall capability.
Decide which circuits really need backup
Whole-home coverage can mean backing up selected essential circuits or attempting to power most of the house. The second approach may require a larger inverter, more storage, and a transfer switch or other professionally installed equipment. Many households can reduce system size by excluding high-demand loads such as electric heating, ovens, or vehicle charging during an outage. A common mistake is to size a battery around every appliance without deciding which ones need to operate simultaneously. Ask an electrician to identify the circuits you want supported and confirm the panel connection method before buying.
Check what is included—and what still needs installation
A battery bundle is not always a complete backup system. Some listings focus on battery modules, while others include an inverter; neither detail alone confirms that the package can connect safely to your home panel. Verify whether a transfer switch, wiring, monitoring hardware, and required protection equipment are included or sold separately. Also confirm that the inverter and battery communicate with each other and that the components are approved for the intended configuration. Buyers who overlook these details can face extra equipment costs or a system that needs more planning than expected. Get a written installation scope before committing to a battery-only package.
Plan for outage length and recharge options
Backup duration depends on daily consumption, not just the capacity printed on a product page. Estimate the energy use of the loads you will keep on, then allow for conversion losses and changing conditions. Solar can extend runtime, but panel wattage, placement, weather, and available daylight limit how quickly a battery refills. A bundled panel set may be useful for topping up a portable station, yet it may not replenish a large household system fast enough to meet all needs. If outages often last several days, compare supported solar input and generator charging options alongside battery capacity.
Choose between permanent integration and portability
Portable stations are easier to reposition and can serve different areas or trips, but they may need additional equipment to feed household circuits. Larger inverter-and-battery systems are better suited to a defined home installation, though they involve more planning and can be harder to move. Think about where the unit will live, how it will be ventilated, and whether its weight and dimensions work for that space. Do not assume a portable design automatically means simple whole-home connection. The right format depends on whether you value a dedicated home setup or flexibility across several uses.
Compare expansion limits and long-term service needs
Expandable capacity only helps when the system supports the right components. Confirm the maximum battery configuration, compatible module models, and any limits on inverter output before planning to add storage later. Ask how firmware, replacement batteries, and warranty support are handled, especially when a system combines components bought at different times. A modular design can spread a large purchase across stages, but mixing incompatible hardware can create service and performance problems. Also check the manufacturer’s installation requirements and the availability of qualified support in your area. Paying for a system with clear expansion rules may be more useful than buying a larger battery that cannot grow with your needs.
Frequently Asked Questions
Can one of these systems power my entire house during an outage?
That depends on your home’s peak load and wiring, not on the product name. A system with a 10kW inverter can supply more simultaneous power than a smaller portable unit, but large loads may still exceed its output. Heating, air conditioning, electric cooking, and vehicle charging can quickly raise demand. Have an electrician review your panel and identify which circuits can be backed up together. Many buyers get a more workable system by prioritizing essentials instead of trying to run every appliance at once.
Is a battery-only package enough to provide whole-home backup?
Usually, a battery needs compatible inverter and home-connection equipment before it can serve household circuits. Check the listing for included components, then confirm the manufacturer approves the exact battery-inverter combination. Panel connection may require a transfer switch, electrical work, and local permits. A two-pack of batteries can offer considerable storage without being a ready-to-install backup system. Ask the installer to identify every required component and labor item before choosing between a battery bundle and an integrated package.
Should I choose a 10kW inverter or a larger battery?
Choose based on the problem you need to solve. More inverter output helps run multiple or high-demand appliances at the same time, while more battery capacity extends runtime. If your planned loads exceed the inverter’s rating, extra storage will not fix that limit. If the inverter can handle your loads but power runs out too soon, added capacity may help. Make a list of essential appliances, their running and startup demands, and how many hours you want them operating before deciding which specification deserves priority.
Can portable power stations connect to my home’s electrical panel?
Some portable systems can support home circuits, but the connection method varies. A compatible transfer device or other approved equipment may be needed, and not every station can feed a full panel. Check the manufacturer’s supported setup and have a qualified electrician confirm code requirements; never connect a power station to household wiring through an improvised method. Portable stations can still be useful for individual appliances when panel integration is not part of the plan. Their convenience does not automatically equal whole-home coverage.
Will solar panels keep a home battery charged through a multi-day outage?
Solar can extend backup time, but it cannot promise uninterrupted power. Recharging depends on panel capacity, weather, shading, daylight hours, and how much energy the household uses. A small panel bundle may replenish a portable station gradually, while larger systems need enough supported solar input to match their consumption. Estimate the daily energy needed for essential loads and compare it with realistic solar production for your location. For cloudy periods or heavy loads, consider whether grid charging before an outage or a compatible generator is part of your backup plan.
Conclusion
For a buyer seeking a strong balance of storage and home-backup capability, I recommend the EcoFlow DELTA Pro Ultra 12kWh as my best overall pick. The ECO-WORTHY 30,720Wh system is my best value-oriented choice for buyers who put a premium on large storage, provided its installation and included components match their needs. For a premium, high-capacity setup, compare those two systems closely and favor the one with the clearer expansion and installation plan. Beginners who want a more approachable portable format should start with the Jackery Explorer 5000 Plus, while accepting that it may not deliver the same home integration as a dedicated system. For targeted backup and portability, the Anker SOLIX F3800 or Jackery HomePower 3600 Plus may fit better; for buyers assembling a system around battery modules, the ECO-WORTHY Powermega two-pack is a specific option, but only after confirming inverter compatibility and home-connection requirements.
