Model-Specific Results

3 of 3 models are SAFE or TIGHT. Most demanding model: Wayne CDU800 (1/2 HP) (3,381W surge).

Model Running Surge Verdict Runtime Source
Zoeller M98 Flow-Mate (1/2 HP) 1,081W 3,243W Tight ~1.0h NEC Standard
Show expert analysis

Technical: **Running load:** 1,081W (115V x 9.4A OEM rated). **Surge:** 3,243W at motor startup (3x NEC estimate). **Voltage:** 120V AC. The cast iron PSC motor draws heavy inrush current on every pump cycle.

Field note: The Zoeller M98 is the industry reference in cast iron sump pumps. Its PSC motor has no built-in soft-start โ€” the full inrush hits the power station instantly. An external soft-start device can reduce this surge, but size the inverter for the full 3,243W if running without one.

Can I run a Zoeller M98 sump pump on a portable power station during a flood?

Only if your power source can supply at least 1,081W continuous and 3,243W surge at 120V. The PSC motor creates a hard startup spike that will trip undersized inverters.

Wayne CDU800 (1/2 HP) 1,127W 3,381W Tight ~0.9h NEC Standard
Show expert analysis

Technical: **Running load:** 1,127W (NEC 430.248 rated). **Surge:** 3,381W at motor startup (3x NEC estimate). **Voltage:** 120V AC. The coated steel PSC motor draws the highest inrush in this class due to its conservative NEC-rated amperage.

Field note: The Wayne CDU800 is the Home Depot best-seller for suburban basements. Without OEM amperage data, specs are derived from NEC tables โ€” the actual draw may be slightly lower, but sizing to NEC ensures safe headroom.

Can I keep my Wayne sump pump running on battery backup during a storm?

Only if your power source can supply at least 1,127W continuous and 3,381W surge at 120V. The motor startup surge is the critical factor โ€” most small power stations cannot handle it.

Liberty Pumps 287 VMF (1/2 HP) 920W 2,645W Safe ~1.2h OEM Manual
Show expert analysis

Technical: **Running load:** 920W (115V x 8.0A OEM rated). **Surge:** 2,645W at motor startup (115V x 23A LRA, OEM verified). **Voltage:** 120V AC. The 3450 RPM PSC motor with OEM-documented LRA provides the most precise surge data in this class.

Field note: The Liberty 287 is the plumber's choice and the most battery-friendly 1/2 HP sump pump in this comparison. With OEM-verified LRA data, the 2,645W surge is a confirmed number โ€” not an estimate. A 3,000W power station can handle this reliably.

Is the Liberty 287 easier to run on a power station than other sump pumps?

Only if your power source can supply at least 920W continuous and 2,645W surge at 120V. Its OEM-documented 23A locked rotor current is lower than NEC estimates for competing 1/2 HP pumps, making it more generator-friendly.

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.

Technical Analysis

Spec-Based โ€ข No Guarantees

Technical Breakdown

Running load: 920โ€“1,127W depending on model. Surge: 2,645โ€“3,381W at motor startup. Voltage: 120V AC required. All 1/2 HP sump pumps use PSC induction motors with significant startup inrush โ€” the surge is the critical sizing factor for battery backup.

Expected Behavior

Estimated runtime: ~0.9h. Sump pumps activate automatically via float switch during flooding. Each motor start produces a surge lasting 1-3 seconds. Typical storm usage: 2 hours/day with intermittent cycling. Daily energy: 1,840โ€“2,254 Wh.

Field Note

Sump pump backup is the #1 emergency use case for portable power stations. The motor startup surge โ€” not the running watts โ€” determines whether your power station can handle it. Check the surge rating, not just the wattage.

Frequently Asked Questions

Can the Goal Zero Yeti 1500X power a Sump Pump?

It depends on the model. 3 of 3 Sump Pump (1/2 HP) models are compatible with the Goal Zero Yeti 1500X. See the model-specific results table for exact verdicts per model.
