Best overall
EcoFlow DELTA 3 Max Plus
Why it ranks here
The strongest output envelope for a professionally reviewed furnace-backup plan and the most room for additional essential loads.
- Direct price
- $1,199
- Rated capacity
- 2,048 Wh
- Continuous AC
- 3,000 W
- Published peak
- 6,000 W
- Solar input
- 1,000 W
- Weight
- 49.6 lb
Value context: The highest captured direct price in the 2kWh group. It earns the premium only when 3,000W continuous output, published 6,000W surge, or expansion matters.
- Best for
- A measured furnace with meaningful blower startup and a broader home-outage plan.
- Skip it if
- The furnace load is modest and a lighter, less expensive 2kWh station clears every requirement.
What works
- 3,000W continuous output
- Published 6,000W surge
- Expandable 2kWh platform
Tradeoffs
- Highest captured direct price
- 49.6 lb body
Best for easier handling
Jackery Explorer 2000 v2
Why it ranks here
A 2kWh furnace candidate with a published peak rating and substantially less weight than the other two.
- Direct price
- $999
- Rated capacity
- 2,042 Wh
- Continuous AC
- 2,200 W
- Published peak
- 4,400 W
- Solar input
- 400 W
- Weight
- 39.5 lb
Value context: The middle captured direct price in the 2kWh group. Its 39.5 lb weight is the reason to pay more than the lowest-priced option.
- Best for
- A furnace that clears 2,200W continuous and 4,400W peak, especially when the station must be moved.
- Skip it if
- Your measured blower start needs the larger EcoFlow envelope.
What works
- 39.5 lb weight
- Published 4,400W peak
- 2,042Wh rated capacity
Tradeoffs
- 400W documented solar configuration
- Not expandable
Best continuous-output value
BLUETTI Elite 200 V2
Why it ranks here
Strong sustained output, high solar input, and the lowest captured direct price in the group for a furnace with verified startup compatibility.
- Direct price
- $899
- Rated capacity
- 2,073.6 Wh
- Continuous AC
- 2,600 W
- Published peak
- Not separately published
- Solar input
- 1,000 W
- Weight
- 53.4 lb
Value context: The lowest captured direct price in the 2kWh group, with 2,600W continuous output and 1,000W solar input. Weight and missing general surge data are the compromises.
- Best for
- A measured furnace profile below 2,600W continuous where solar recharge matters.
- Skip it if
- You need a published general surge figure for blower approval.
What works
- 2,600W continuous output
- 1,000W maximum solar input
- Lowest captured direct price
Tradeoffs
- No general surge rating used in this record
- Heaviest at 53.4 lb

Calculation: rated capacity × 80% after reserve × 88% AC efficiency × 95% environmental factor, divided by the cycling average load.
Motor type, thermostat calls, ignition, condensate equipment, neutral behavior, and connection method can change the answer. Measure the complete furnace cycle and use a qualified installer for hardwired work.
Solar refill floor is rated capacity divided by maximum published solar input. It excludes weather, panel angle, temperature, charge taper, and conversion losses. Runtime does not prove voltage, startup, transfer, wiring, medical, flood-prevention, or combustion safety compatibility.
Research method
How we ranked gas-furnace backup stations
Every recommendation assumes a measured, electrically compatible 120V furnace and a listed connection method reviewed for the exact installation.
We compare official specifications, manuals, support records, current manufacturer pricing, and transparent planning calculations. We do not assign lab scores or claim hands-on testing that did not occur.
- Connection safety
- Transfer equipment, neutral behavior, grounding, and furnace controls are pass or fail requirements.
- Blower startup
- Motor startup evidence is evaluated separately from continuous output.
- Heating-cycle energy
- Runtime is based on measured ignition, blower, and control energy across complete cycles.
- Shared outage value
- Weight, solar, price, and spare inverter headroom matter after the furnace clears the electrical review.
