Model-Specific Results
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 | ~0.8h | OEM Manual |
Show expert analysisTechnical: **Running load:** 886W (115V × 7.7A FLA, OEM rated). **Surge:** 1,461W (115V × 12.7A start amps, OEM rated). **Voltage:** 120V AC. The ECM variable speed blower ramps up electronically with a controlled startup — 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 | ~0.7h | Engineering Est. |
Show expert analysisTechnical: **Running load:** 1,058W (115V × 9.2A FLA, OEM rated). **Surge:** 1,587W estimated (1.5× for ECM constant torque motor — 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 | ~0.9h | NEC Standard |
Show expert analysisTechnical: **Running load:** 810W (derived from OEM Min Circuit Ampacity 8.8A de-rated by NEC 1.25× factor). **Surge:** 2,430W (3× running per NEC for PSC induction motor — OEM LRA not published). **Voltage:** 120V AC. The 4-speed PSC motor creates a hard mechanical inrush on every startup — 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 — 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 — 3× 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. | |||||

Installation warning
These systems are often hardwired to a home panel. To run them from a portable station, you may need a transfer switch installed by an electrician. You cannot just plug it in.

Generator Insights
The 3600W surge capacity can support typical residential motor startup scenarios including refrigerator compressors, well pumps, and power tools with inductive loads. The 1024Wh capacity sustains the 1800W continuous rating for approximately 34 minutes at full draw. This configuration can handle brief high-demand events common in backup power and job site applications.
LFP chemistry provides stable electrochemical performance under load cycling. The 3600W surge rating indicates transient overcurrent capability designed for inductive startup events.

Technical Analysis
Spec-Based • No GuaranteesTechnical Breakdown
Running load: 810–1,058W depending on motor type (ECM vs PSC). Surge: 1,461–2,430W. Voltage: 120V AC required. The motor technology — ECM variable speed, ECM constant torque, or PSC multi-speed — determines both the running draw and the startup surge that your power station must handle.
Expected Behavior
Estimated runtime: ~0.7h. Gas furnace blowers run 8+ hours per day during winter emergencies. ECM motors (Carrier, Trane) have controlled electronic startup. PSC motors (Goodman) create hard mechanical inrush at 3× running watts on every heating cycle. Daily energy ranges from 6,480–8,464 Wh.
Field Note
The blower motor is the only significant electrical load in a gas furnace — the gas burner itself uses negligible electricity. Check your furnace nameplate for motor type: ECM or constant torque means manageable surge; PSC or multi-speed means you need a power station rated for at least 2,500W surge.
