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 | Safe | ~2.0h | NEC Standard |
Show expert analysisTechnical: **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 — 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 | Safe | ~1.9h | NEC Standard |
Show expert analysisTechnical: **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 — 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 — most small power stations cannot handle it. | |||||
| Liberty Pumps 287 VMF (1/2 HP) | 920W | 2,645W | Safe | ~2.3h | OEM Manual |
Show expert analysisTechnical: **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 — 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. | |||||

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 7000W surge rating handles demanding startup loads including well pumps, air compressors, and window AC units. The dual 1200W MPPT controllers accept high-voltage panel strings (up to 150V), enabling efficient solar recharging in 1.5–2 hours with 2400W of panels. At 3072Wh base capacity, expect 8+ hours of runtime on moderate loads. The expansion to 15kWh rivals whole-home battery systems.
The E3600LFP uses LiFePO4 chemistry rated for 3,500+ cycles to 80% capacity. The 51.2V battery architecture and UPS function (8–20ms switchover) make it suitable for sensitive electronics and home backup. The TT30-R RV outlet follows NEMA standards for safe 30A connections.

Technical Analysis
Spec-Based • No GuaranteesTechnical Breakdown
Running load: 920–1,127W depending on model. Surge: 2,645–3,381W at motor startup. Voltage: 120V AC required. All 1/2 HP sump pumps use PSC induction motors with significant startup inrush — the surge is the critical sizing factor for battery backup.
Expected Behavior
Estimated runtime: ~1.9h. 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: 1,840–2,254 Wh.
Field Note
Sump pump backup is the #1 emergency use case for portable power stations. The motor startup surge — not the running watts — determines whether your power station can handle it. Check the surge rating, not just the wattage.
Frequently Asked Questions
