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 | ~3.2h | 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 | ~2.6h | 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 | ~3.5h | 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. | |||||

Before You Buy: Connection Check
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 7200 W surge can handle typical compressor-based appliances like well pumps, refrigerators, and air conditioning startup events on 120V circuits. The 3600 W continuous rating supports sustained operation once inrush currents settle, making this unit a strong option for heavy 120V backup loads.
This unit uses LFP chemistry and draws from manufacturer documentation for its output specifications. The 7200 W surge rating reflects the inverter's transient capacity, not a thermal or safety certification.

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: ~2.6h. 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.
