Home Battery Backup

Home battery backup systems are available in three configurations: portable plug-and-play units that power essential circuits without permanent installation, partial-home backup systems that integrate with the electrical panel via transfer switches to power selected circuits, and whole-home backup systems with capacity scaling up to 60+ kWh through expansion battery modules supporting full-home electrical loads including well pumps, central air conditioning, and electric heating.

The Trade Table carries home battery backup systems from Bluetti and EcoFlow — covering the full range from portable backup units up to expandable whole-home systems with 240V dual-voltage support, solar input compatibility, and smart app monitoring for residential and small commercial backup applications.

A home battery backup system replaces the gas-powered standby generators that traditionally protected homes from grid outages. The advantages over gas generators are significant: silent operation, zero emissions (safe for indoor installation), no fuel storage or refilling, no engine maintenance, instant automatic transfer when grid power fails, and compatibility with sensitive electronics like medical equipment, computers, and smart home systems that gas generators can damage with unstable power output.

Bluetti AC500 + B300S is a stackable whole-home backup system delivering 6,000W AC output with 240V dual-voltage support — capable of running well pumps, electric water heaters, central air conditioning, and full home electrical loads during outages. The system supports up to 5 expansion batteries for total capacity of 18,432Wh (18.4kWh), making it suitable for partial whole-home backup of essential circuits during multi-day outages. The AC500 base unit is compatible with B300S expansion batteries that stack vertically for capacity expansion without additional outdoor space.

Bluetti EP500 Pro is a wheeled home backup power station with 5,100Wh capacity and 3,000W AC output — designed for partial-home backup of refrigerators, lighting circuits, communications equipment, and medical devices during outages. The EP500 Pro plugs into a standard outlet for charging and delivers backup power through onboard AC outlets or via UPS connection to selected circuits.

Bluetti EP900 + B500 is a dedicated whole-home backup system supporting up to 60kWh+ expandable capacity through B500 battery modules. The EP900 system is designed for permanent installation with transfer switch integration — providing true off-grid home power capability paired with solar panels, or grid-charged whole-home backup for buyers in regions with frequent or extended outages.

EcoFlow DELTA Pro and DELTA Max series deliver portable-to-permanent backup capability. The DELTA Pro at 3,600Wh expands up to 25kWh with smart extra batteries — supporting partial whole-home backup with X-Stream fast charging that recharges from grid in 1.7 hours. EcoFlow Smart Home Panel integration allows the DELTA Pro to back up 10 selected circuits in the home's main electrical panel automatically.

Solar generator configurations pair home backup systems with foldable or rigid solar panels — providing grid-independent recharging during extended outages and offsetting daily grid consumption during normal operation. Solar input capacity on flagship systems reaches 1,200W or more, supporting full off-grid charging from a single day of good sunlight.

Home Battery Backup FAQs

What is a home battery backup system?

A home battery backup system is a stationary energy storage unit that powers a home's electrical circuits during grid outages. The system stores energy in lithium iron phosphate (LiFePO4) battery cells charged from the grid, solar panels, or both, and automatically delivers stored power through the home's electrical panel when grid power fails. Modern systems integrate with the main electrical panel via transfer switches for automatic operation — eliminating the noise, fumes, and maintenance of traditional gas-powered standby generators.

How long does a home battery backup last during an outage?

Runtime depends on the system's capacity (kWh) and the home's electrical load during the outage. A 5kWh system running essential circuits (refrigerator, lights, internet, medical equipment, phone charging) typically provides 12-24 hours of backup. A 10kWh system extends this to 1-2 days. A 25kWh system supports 3-5 days of essential backup. Whole-home backup including HVAC requires significantly larger capacity — 30-60kWh+ for multi-day full-home operation. Solar input extends runtime indefinitely if daily solar generation matches consumption.

What is the difference between partial-home and whole-home backup?

Partial-home backup powers selected essential circuits — typically refrigerators, communications, lighting, and medical equipment — through dedicated transfer switches or smart panel integration. Whole-home backup powers all home electrical circuits including HVAC, water heaters, well pumps, and electric ranges through main panel integration. Partial-home backup requires smaller capacity (5-10kWh) and lower upfront cost. Whole-home backup requires significantly larger capacity (20-60kWh+) and higher cost but maintains full home electrical service during outages.

How much does a home battery backup system cost?

Home battery backup costs vary significantly by capacity and installation type. Portable plug-and-play units (3,000-5,000Wh) for partial-home backup run $2,500-$4,500. Mid-capacity expandable systems (10-15kWh) run $5,000-$10,000+. Whole-home backup systems (20-60kWh+) run $15,000-$40,000+ including expansion batteries and transfer switch installation. Solar generator configurations add $1,500-$5,000 for solar panels depending on system size. Federal tax credits and utility rebates can offset 30%+ of qualifying installation costs.

Can a home battery backup power my whole house?

Yes — with the right capacity and configuration. The Bluetti AC500 + B300S stackable system supports up to 18,432Wh (18.4kWh) total capacity with 6,000W AC output and 240V dual-voltage — sufficient for partial whole-home backup including well pumps, water heaters, and selected HVAC. The Bluetti EP900 + B500 system scales to 60kWh+ for true whole-home off-grid capability. EcoFlow DELTA Pro expanded with smart extra batteries reaches 25kWh for similar partial whole-home applications. Whole-home installations require transfer switch installation by a licensed electrician.

Can I charge a home battery backup with solar panels?

Yes. All Bluetti and EcoFlow home battery backup systems include solar input ports compatible with portable foldable solar panels and rigid roof or ground-mount solar arrays. Solar input capacity varies by model — flagship systems accept 1,200W+ solar input for fast off-grid recharging. Solar input on home backup systems serves two purposes: (1) extending runtime during extended outages by recharging during daylight, and (2) offsetting daily grid consumption during normal operation by storing solar generation for evening use.

Do home battery backups qualify for tax credits?

Many home battery backup systems qualify for the Federal Residential Clean Energy Credit (formerly Solar Investment Tax Credit) when installed in connection with a solar electric system or as a standalone storage installation. The current credit is 30% of qualifying equipment and installation costs through 2032. State and utility rebate programs may provide additional incentives. Consult a tax professional and check current federal and state programs before purchasing — incentive availability varies by location and qualifying installation type.
