3 of 3 models are SAFE or TIGHT. Most demanding model: Goodman GMH8 0805B (80,000 BTU) (2,430W surge).
| Model | Running | Surge | Verdict | Runtime | Source |
|---|---|---|---|---|---|
| Carrier Infinity 59MN7A 080 (80,000 BTU) | 886W | 1,461W | Safe | ~4.9h | OEM Manual |
Show expert analysisTechnical: **Running load:** 886W (115V ร 7.7A FLA, OEM rated). **Surge:** 1,461W (115V ร 12.7A start amps, OEM rated). **Voltage:** 120V AC. The ECM variable speed blower ramps up electronically with a controlled startup โ the 1,461W surge is brief and predictable. Field note: The Carrier Infinity is the most generator-friendly furnace blower in this comparison. The ECM variable speed motor keeps both running and surge watts low. Most power stations above 1,500W can handle this unit without issue. Can I run a Carrier Infinity furnace on a portable power station during a winter outage? Only if your power source can supply at least 886W continuous and 1,461W surge at 120V. The ECM variable speed blower has a controlled startup that most mid-size power stations can handle. | |||||
| Trane S8X1 B080 (80,000 BTU) | 1,058W | 1,587W | Safe | ~4.1h | Engineering Est. |
Show expert analysisTechnical: **Running load:** 1,058W (115V ร 9.2A FLA, OEM rated). **Surge:** 1,587W estimated (1.5ร for ECM constant torque motor โ OEM start amps not published). **Voltage:** 120V AC. The 3/4 HP constant torque ECM blower draws more than the Carrier variable speed but still benefits from electronic startup control. Field note: The Trane S8X1 is a mid-range 80% AFUE furnace common in existing homes. The 9-speed ECM blower is more efficient than old PSC motors but draws more than premium variable speed models. A 2,000W power station provides adequate headroom. Can I keep my Trane furnace running on battery backup during a winter storm? Only if your power source can supply at least 1,058W continuous and 1,587W surge at 120V. The ECM blower has a moderate startup demand that most 2,000W+ power stations can handle. | |||||
| Goodman GMH8 0805B (80,000 BTU) | 810W | 2,430W | Safe | ~5.3h | NEC Standard |
Show expert analysisTechnical: **Running load:** 810W (derived from OEM Min Circuit Ampacity 8.8A de-rated by NEC 1.25ร factor). **Surge:** 2,430W (3ร running per NEC for PSC induction motor โ OEM LRA not published). **Voltage:** 120V AC. The 4-speed PSC motor creates a hard mechanical inrush on every startup โ three times the running load. Field note: The Goodman GMH8 represents millions of builder-grade furnaces installed across the US. The PSC motor surge is the critical factor โ running watts are actually lower than ECM models, but the 2,430W startup spike will trip any power station under 2,500W. This is the #1 reason furnace blowers fail on small generators. Why does my power station shut off when the Goodman furnace blower starts? Because the PSC blower motor creates a 2,430W startup surge โ 3ร its 810W running draw. Most power stations under 2,500W surge capacity will trip on this inrush. You need a station rated for at least 2,430W surge to handle it reliably. | |||||

With 12000 watts of surge capacity, this system can handle typical startup loads for central air compressors, well pumps, and other motor-driven equipment common in residential settings. The 6000-watt continuous rating supports sustained operation of multiple high-draw appliances simultaneously. The 6144 Wh capacity provides meaningful runtime for essential circuits during grid outages.
This unit uses lithium iron phosphate (LFP) chemistry, known for stable thermal behavior in stationary storage applications. The system is designed with internal protections typical of grid-tied and off-grid battery platforms. Source: EcoFlow DELTA Pro Ultra User Manual (manufacturer documentation).

Yes. The EcoFlow Delta Pro Ultra provides 6000W running / 12000W surge. The Gas Furnace Fan (Blower) needs 1217W / 2795W (including 15% buffer). That leaves 4783W of running headroom and 9205W of surge margin.
Approximately 4.1 hours, based on the Gas Furnace Fan (Blower)'s 1058W draw and the Delta Pro Ultra's 6144Wh capacity (70% usable after real-world losses).
With 1780W allocated to the Gas Furnace Fan (Blower), the Delta Pro Ultra still has ~1962W of margin. These devices could run simultaneously:
Power Tip: To get the most out of your Delta Pro Ultra, keep it in a well-ventilated area. Extreme temperatures can slightly reduce the efficiency of the LFP/NMC cells.

Ranked by budget, runtime, and overall compatibility.
Derived from variant list (max of variants). Worst case running = Trane S8X1 B080 (1058W). Worst case surge = Goodman GMH8 080 (2430W). Running and surge maxima come from different variants due to ECM vs PSC motor technology.
