Complete 3–4kWh backup list
Every 3,000–4,000 Wh home-backup station we track
The complete tracked list of expandable backup systems sitting between portable stations and installed home batteries — every model in the band, not a shortlist.

Lineup at a glance
All 14 tracked stations with a sourced rated capacity 2,201–4,200 Wh, listed in full — this page never trims the band to a shortlist. For the scored shortlist, the Best 3,000 Wh stations ranking applies the BatteryRank composite to this same pool and publishes only the top scorers.

Frequently asked
- How is this different from the Best 3,000 Wh stations ranking?
- This page is the inventory: all 14 tracked models inside the band, in catalog order, so nothing is hidden from you. The ranking is the shortlist — it applies the BatteryRank composite and publishes only the top scorers. Come here to see what exists; go there to see what scores best. Best 3,000 Wh stations →
- Is every 3–4kwh backup model on this page?
- Every model BatteryRank tracks with a sourced rated-capacity reading inside the band appears here — currently 14. A model with no sourced capacity figure is withheld rather than estimated into a band it may not belong in.
- How are models included in this size class?
- A station is included by its sourced rated watt-hours and the published class boundaries shown on this page. Models outside the band belong to an adjacent size page.
- Is the highest-capacity model here automatically the best?
- No. More capacity usually brings different weight, output, charging, expansion, and price tradeoffs. Capacity decides which page a model appears on; it decides nothing else.
- How much usable AC energy should I expect?
- Usable AC energy is lower than nameplate capacity because of conversion losses. Model cards show a measured range when credible independent data exists; otherwise they show a transparent estimate.
- Can this size run a refrigerator or CPAP?
- Runtime depends on the device draw, duty cycle, settings, and conversion path. Use the device-specific tools rather than a generic size-page promise. Estimate your load →
- Why is price not part of the score?
- Price changes daily; a station’s hardware does not. Keeping price out of the score means a discount can never buy a better rank, and the score you read today means the same thing next week.
- Where are exact model matchups?
- Model-vs-model pages own exact head-to-head decisions. This page owns the broader capacity-class search. Compare exact models →
- Are all specifications verified?
- No. Manufacturer claims are labeled claimed; credible independent or regulatory evidence is labeled verified. A missing reading stays N/A.
