Model-Specific Results
3 of 3 models are SAFE or TIGHT. Most demanding model: Red Lion RL12G10-2W2V (1 HP Deep Well Submersible) (7,176W surge).
| Model | Running | Surge | Verdict | Runtime | Source |
|---|---|---|---|---|---|
| Wayne SWS100 (1 HP Shallow Well Jet Pump) | 1,840W | 5,520W | Safe | ~1.6h | NEC Standard |
Show expert analysisTechnical: **Running load:** 1840W using NEC full-load current for a 1 HP single-phase motor at 230V. **Startup surge:** 5520W estimated with a 3x motor inrush multiplier. **Voltage:** 240V required in normal US installation. Field note: Wayne publishes HP and voltage, but not FLA/LRA for SWS100. Sizing is intentionally conservative using NEC motor tables. Can a portable power station run the Wayne SWS100? Only if it provides 240V output and can handle about 1840W continuous plus a 5520W startup spike. | |||||
| Red Lion RL12G10-2W2V (1 HP Deep Well Submersible) | 2,392W | 7,176W | Tight | ~1.2h | NEC Standard |
Show expert analysisTechnical: **Running load:** 2392W from OEM voltage/current data (230V × 10.4A). **Startup surge:** 7176W estimated at 3× running per NEC 430.248 due to high-inrush induction motor behavior. **Voltage:** 240V required. Field note: This is the battery-killer profile in the set: high running watts plus very high startup inrush. Why does this Red Lion model fail on many power stations? Because the startup surge is very high relative to consumer inverter surge limits, even when continuous watts look close. | |||||
| Grundfos 15SQ10-220 (SQ Series Soft Start) | 1,702W | 2,553W | Safe | ~1.7h | Engineering Est. |
Show expert analysisTechnical: **Running load:** 1702W from OEM full-load amps. **Estimated startup surge:** 2553W using a 1.5x soft-start assumption. **Voltage:** 240V required. Field note: This is the generator-friendly profile in the set: still a 240V well-pump load, but with meaningfully lower startup demand. Is the Grundfos SQ easier on battery inverters than standard well pumps? Generally yes, because the SQ line uses soft-start behavior that lowers startup inrush compared with hard-start 1 HP pumps. | |||||

Before You Buy: Connection Check
High-voltage device
This device typically needs 240V split-phase or a hardwired connection. Most portable stations are 120V-only. Verify the plug type and voltage on the device label/manual before purchase.
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 8000W surge rating can support typical compressor startup in residential air conditioners, well pumps, and refrigeration equipment. Most single-phase motor loads under 2HP can start on this surge budget. The 4000W continuous capacity can handle simultaneous operation of multiple circuits including HVAC blowers, lighting, and standard appliances during extended outages.
This unit provides 4096Wh of LFP battery capacity with 4000W continuous and 8000W surge output capability. Source: EcoFlow DELTA Pro 3 User Manual v1.1 (AC Output Specifications) (manufacturer documentation). The LFP chemistry offers thermal stability compared to older lithium-ion chemistries, though all battery systems require proper ventilation and adherence to installation guidelines.

Technical Analysis
Spec-Based • No GuaranteesTechnical Breakdown
Running range: 1702W to 2392W across common 1 HP well pump designs. Startup range: 2553W to 7176W depending on motor/start behavior. Voltage: 240V class load in typical US installations.
Expected Behavior
Estimated runtime: ~1.2h. Typical duty cycle is about 2 hours/day, with short frequent cycles. Daily energy falls around 3404 to 4784Wh depending on the model.
Field Note
For well pumps, startup behavior matters more than nameplate HP. A soft-start design can change a borderline pairing into a stable one.
