Anker SOLIX F3000 vs EcoFlow Delta Pro 3
This is the decision that matters if you are wiring a station into your house rather than carrying it to a campsite. Both of these units output 240V, both expand to roughly 24 kWh, and both are designed to feed household circuits through a transfer switch or home panel. The difference is roughly 1,000 Wh of capacity, 3,100W of surge, and a very large price gap — so the real question is whether the Delta Pro 3's extra headroom is worth it for your load list.

By Quick Verdict
Anker SOLIX F3000
Our Best for Emergencies 2026 winner, and the value pick of the tier. 3,072 Wh expandable to 24 kWh with 240V split-phase capability, and 6,000W AC recharge — the fastest way to refill a battery of this size when grid power returns between rolling outages. It is the unit that wins because it is more than sufficient for most houses at a much lower entry price.
- ✓ You want whole-home capability without paying flagship prices
- ✓ Refilling fast after an outage matters — 6,000W AC recharge is exceptional
- ✓ 3,072 Wh covers your essential circuits (check with our sizing calculator first)
- ✓ You want the same 24 kWh expansion ceiling for considerably less money up front
EcoFlow Delta Pro 3
The premium reference point, and our highest-rated product at 95/100. 4,096 Wh with 4,000W continuous, an 8,000W surge ceiling, and 240V split-phase output. If your load list includes hard-starting motors or you want the largest single-unit capacity we cover, nothing here beats it on raw capability.
- ✓ Your loads include hard-starting motors that need surge headroom — 8,000W vs 4,860W
- ✓ You want the largest single-unit capacity available (4,096 Wh vs 3,072 Wh)
- ✓ You are building around EcoFlow’s home-panel accessory for automatic changeover
- ✓ You want the highest-rated unit in our testing and the widest ecosystem of expansion options
Bottom line
For most households the Anker SOLIX F3000 is the smarter buy: 24 kWh of expansion headroom, 240V output, and a 6,000W recharge rate that genuinely changes how an outage plays out — for a fraction of the Delta Pro 3’s price. Choose the EcoFlow Delta Pro 3 when the extra 1,024 Wh, the 8,000W surge ceiling, or the EcoFlow home-panel ecosystem is specifically what your installation needs. If you cannot articulate which of those three you need, you probably do not need it.

Which One for Your Situation
Specs are only half the decision. Here is how each unit behaves in the scenarios buyers in this tier actually care about.
Whole-home backup with a transfer switch
SOLIX F3000
Covers the standard essential-circuit list — furnace blower, refrigerator, freezer, well pump, lighting — with 24 kWh of expansion room. This is the setup most households should be pricing.
Delta Pro 3
The same plan with more margin. Where it pulls ahead is anything with a heavy startup draw, and installations where you want to eventually run larger hardwired loads.
Surge-heavy loads
SOLIX F3000
4,860W of surge is enough for a typical furnace blower and most pumps, but it is the tighter of the two ceilings.
Delta Pro 3
A clear win. 8,000W of surge is what lets you start hard-drawing motors that would trip a smaller inverter. If your load list has a large well pump or a big compressor, this is the deciding row.
Refilling between outages
SOLIX F3000
The standout advantage. 6,000W AC input is exceptionally fast for this capacity, so short windows of grid power are enough to top up.
Delta Pro 3
Good, but slower on AC input. During a rolling-blackout event, the Anker refills in fewer windows.
Recharging from solar
SOLIX F3000
2,400W of solar input supports a large array, giving you meaningful independence during a multi-day outage.
Delta Pro 3
2,600W of solar input — marginally higher ceiling. In practice panel count and mounting decide this more than the 200W difference.
Budget and value
SOLIX F3000
The value leader. Whole-home capability, 240V output and the same 24 kWh ceiling for materially less money on day one.
Delta Pro 3
The premium option. You are paying for capacity, surge and ecosystem — all real, but only worth it if your load list uses them.
Portability
SOLIX F3000
At 91.5 lb this is a two-person move. Realistically it stays where you put it.
Delta Pro 3
At 113.5 lb, effectively stationary. Neither of these is a camping unit — if you want one battery for both jobs, look at a 2 kWh class unit instead.
SOLIX F3000 vs Delta Pro 3: FAQ
Which is better, the Anker SOLIX F3000 or the EcoFlow Delta Pro 3?
For most households, the Anker SOLIX F3000 — it delivers whole-home capability with 240V output, a 24 kWh expansion ceiling and exceptional recharge speed for substantially less money. The EcoFlow Delta Pro 3 is the better unit when you specifically need the extra 1,024 Wh, the higher 8,000W surge ceiling, or EcoFlow’s home-panel ecosystem.
How much more capacity does the Delta Pro 3 have?
About 1,024 Wh: 4,096 Wh against 3,072 Wh, so roughly a third more stored energy. Whether that matters depends entirely on your load list — for essential circuits, 3,072 Wh already covers a long outage. Use our solar size calculator to total your own loads.
Do both support 240V output?
Yes. Both support 240V split-phase, which is what allows a station to serve hardwired household loads rather than only plug-in circuits. Confirm the specific outlet you intend to use on each unit, because 240V availability can vary by outlet or configuration. See our transfer switch guide for how this connects.
Which one recharges faster?
The Anker SOLIX F3000, notably — it accepts up to 6,000W of AC input. In a rolling-blackout situation that means fewer and shorter windows of grid power are required to get the battery back to full. The Delta Pro 3 is fast in its own right but does not match that rate.
Which is better for running a furnace in winter?
Both are more than capable. Using our stated assumptions, both units run a furnace blower for the better part of a day. Our furnace guide has the runtime math and the connection options.
Do I need an electrician to install either one?
The station side is plug-in, but connecting either unit to household wiring requires a transfer switch, inlet, or interlock installed by a licensed electrician. Feeding house circuits directly from a portable power source is dangerous and is not a legitimate installation method. Our transfer switch guide covers the options.
Which is the better value?
The Anker SOLIX F3000, unless you can name a specific load or feature that requires the Delta Pro 3’s extra capacity or surge. Both brands discount these models during Amazon sale events — we log both prices daily, so the lowest-logged figures above show what each has actually sold for rather than an inflated list price.
