Our Review

The SOLIX F3000 is where Anker's lineup crosses from "big camping battery" into genuine home-backup territory. At 3,072Wh it runs a fridge for a day-plus, and its standout spec is a 6,000W surge that swallows almost any startup spike you'll throw at it — well-pump, AC, power tools included. If you've ever had a station shut down on a compressor (see Surge Watts vs Running Watts), this one won't.
It's expandable to 24kWh with add-on batteries, takes up to 1,200W of solar, and uses a 3,000-cycle LiFePO4 pack — solid, though it trails the Bluetti Apex 300's 6,000-cycle rating, the highest we list.
One caveat on charging. Anker advertises a 78-minute AC recharge, but that figure runs at 3,600W — and the AC cable in the box is rated 1,800W. Reaching 3,600W requires a TT-30 cable and an EV charging adapter, both sold separately. On the included cable, 3,072Wh divided by 1,800W puts the theoretical floor near 1 hour 42 minutes, and Anker does not publish the actual in-box figure. We score the recharge you get by default. The tradeoff is obvious from the spec sheet: at 79.6 lbs it's a wheeled, two-hands appliance, not something you carry to a campsite.
Pros
- 3,072Wh runs a fridge for 24+ hours
- 6,000W surge handles well pumps, AC, and tools
- Expandable to 24kWh for multi-day backup
- 1,200W solar input recharges fast off-grid
Cons
- 79.6 lbs — home/RV unit, not portable
- 3,000 cycles trails the Bluetti Apex 300's 6,000
- Overkill (and over-budget) for campsite use
What it actually runs
A full 3,072Wh charge yields roughly 2,600Wh usable — enough to push well past a full day on the essentials:
| Load | Typical draw | Runtime per charge |
|---|---|---|
| Full-size fridge | ~65W avg | ~40 hours (≈1.7 days) |
| Outage essentials (fridge + WiFi + lights) | ~200W | ~13 hours |
| CPAP (humidifier on) | 60W | ~43 hours (5 nights) |
| Microwave | 1,000W | ~2.5 hours total runtime |
| Furnace blower | ~300W run | ~8 hours |
Add-on batteries push this to 24kWh, turning a day of backup into most of a week.
Can the SOLIX F3000 run my whole house?
It runs a critical-loads subpanel — fridge, lights, network, a furnace blower or well pump — through a transfer switch, thanks to its 6,000W surge. It isn't a 240V whole-home unit on its own; for 240V appliances step up to a dual-voltage system like the EcoFlow Delta Pro 3.
How long will it power a fridge during an outage?
Around 40 hours on the fridge alone, or roughly 13 hours if you're also running lights, WiFi, and phone charging — comfortably through most grid outages.
Who it's for: homeowners building outage resilience and RVers who want one unit to run everything. For portable trips, step down to the Anker SOLIX C1000 Gen 2 (currently $499.98).
