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 | ~2.3h | 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 | Safe | ~1.8h | 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 | ~2.5h | 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
With 24,000W surge capacity, this system can handle typical compressor startup events found in central air conditioners, well pumps, and refrigeration equipment. The 12,000W continuous rating supports sustained high-load operation across multiple circuits. At 6,144Wh usable capacity, runtime depends on connected load, but this configuration can support whole-home essentials during extended outages.
This unit uses LFP chemistry, a formulation widely recognized for thermal stability in residential backup applications. The manufacturer provides operational guidelines in their documentation, and users should follow all installation and grounding instructions.

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: ~1.8h. 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.
Frequently Asked Questions
Can the EcoFlow Delta Pro Ultra X power a Well Pump?
Yes. The EcoFlow Delta Pro Ultra X provides 12000W running / 24000W surge. The Well Pump (1 HP) needs 2751W / 8253W (including 15% buffer). That leaves 9249W of running headroom and 15747W of surge margin.
How long will the Delta Pro Ultra X run a Well Pump?
Approximately 1.8 hours, based on the Well Pump (1 HP)'s 2392W draw and the Delta Pro Ultra X's 6144Wh capacity (70% usable after real-world losses).
What Else Can You Run?
With 1780W allocated to the Well Pump (1 HP), the Delta Pro Ultra X still has ~5428W of margin. These devices could run simultaneously:
