Key Takeaways

  • Best for: homes that want 3kWh now and a path to whole-home backup with solar
  • Standout: grows to about 12kWh per unit and takes up to 2,400W of solar
  • Watch out: 91.5 lb, and 120V only unless you buy a second unit
  • Not for: anyone who needs to carry their backup battery around

The Anker SOLIX F3000 is a 3,072Wh battery that can keep a fridge, lights, Wi-Fi and bigger appliances going through outages, then grow into a larger home backup system. After Anker’s 2026 price cuts it lists at $1,499 and has dropped to about $1,330 on sale.

Is 3 kWh enough for your home? Use my battery backup calculator to check before you buy.

What it runs in an outage

The Solar Lab measured about 84% efficiency, so expect roughly 2,580Wh of usable power per charge. Estimates with typical US appliances:

  • Full-size fridge: 30 to 40 hours
  • Wi-Fi router and modem: about 5 days
  • CPAP, no heated humidifier: about a week of nights
  • Window AC unit: 3 to 4.5 hours
  • 1,500W space heater: about 1.5 hours

Turning it into home backup

  • Each BP3000 expansion battery adds 3,072Wh and weighs about 55 lb. One F3000 tops out at about 12kWh.
  • Two F3000s linked with Anker’s Double Voltage Hub give you 240V and up to 24kWh.
  • To power home circuits instead of running extension cords, have a licensed electrician install a transfer switch.

Anker SOLIX F3000

Anker SOLIX F3000 review: what 3,072Wh runs in an outage, how it expands to 12kWh or 24kWh, and how it compares with Jackery's HomePower models.

Product Brand: Anker

Product Currency: USD

Product Price: 1329

Product In-Stock: InStock

Editor's Rating:
4.5

Pros

  • Grows from 3kWh to about 12kWh per unit with BP3000 batteries
  • Takes up to 2,400W of solar across two inputs
  • Measured about 84% efficient with a low 20.5W idle draw (The Solar Lab)
  • UL 9540 certified, with a 4,000-cycle LFP battery and 5-year warranty
  • Rated 35 dB at an 1,800W load

Cons

  • At 91.5 lb, it's hard for one person to lift into a car or up stairs
  • AC outlets sit close together, so bulky plugs block their neighbors (The Solar Lab)
  • 120V only; 240V needs a second F3000 plus Anker's hub (BackupPowerHub)
  • Won't work with Anker's older expansion batteries (The Solar Lab)

Verdict

Buy the F3000 if you plan to grow a battery system over time and add serious solar. If you just want 3kWh that one person can move, the lighter Jackery HomePower 3000 is the better fit.

Common Questions

Can I use it indoors?
Yes. It has no exhaust like a gas generator, so it's safe to run and charge indoors.
Can I charge it from a gas generator?
Yes. It accepts generator power through its AC input, and it can combine generator and solar charging at the same time.
Is it safe to use with medical equipment?
It isn't a medical-grade UPS. Check with your device maker before relying on it for a CPAP, oxygen concentrator or other medical equipment.
