Quick Compatibility Check
- 1 Running headroom: target 1297W; generator provides 1800W.
- 2 Startup surge: soft-starter target ~1750W; generator provides 2400W.
- 3 Result: viable only with a soft-starter.
What To Do Instead
- 1 Install a soft-starter: Reduces the Sump Pump (1/2 HP)'s startup surge from 3381W to ~1522W, within the SOLIX C1000's 2400W surge capacity.
- 2 Or size up: Without a soft-starter, you need at least 3889W surge capacity (3381W × 15% buffer).
- 3 No-install alternative: The Explorer 2000 Plus (6000W surge) handles the full 3381W startup natively — no soft-starter needed.

| Model | Running | Surge | Verdict | Runtime | Source |
|---|---|---|---|---|---|
| Zoeller M98 Flow-Mate (1/2 HP) | 1,081W | 3,243W | Soft Start | ~0.7h | 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 | Soft Start | ~0.7h | 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 | Soft Start | ~0.8h | 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. | |||||

Startup Surge
Sump Pump (1/2 HP) vs SOLIX C1000
Startup surge exceeds the power station limit. A soft starter may resolve the surge gap.
With Soft Starter
Sump Pump (1/2 HP) vs SOLIX C1000
Soft start reduces the startup spike and can bring the load under the surge limit.
⚡ Soft-Starter Required
The Sump Pump (1/2 HP)'s startup surge (3381W) exceeds this generator's capacity. A soft-starter can reduce inrush current by ~55%, bringing surge down to approximately 1522W.

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.
No-Install Alternatives to SOLIX C1000
Prefer not to install a soft starter on Sump Pump (1/2 HP)? These generators can start this load natively.

Generator Insights
The 2400 W surge can support typical startup events for refrigerator compressors, well pumps, and other inductive loads in the 1 to 1.5 HP range. The 1800 W continuous rating sustains moderate resistive and mixed loads once motors reach running speed. This combination handles most residential backup scenarios where brief inrush current precedes steady operation.
This unit provides a documented 2400 W surge window to handle motor inrush events without nuisance trips. LFP chemistry offers structural stability under load cycling. Source: Anker SOLIX C1000 User Manual (Output Specs) (manufacturer documentation).

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: ~0.7h. 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
Can the Anker SOLIX C1000 power a Sump Pump?
Conditionally — with a soft-starter. The Anker SOLIX C1000's 2400W surge cannot handle the Sump Pump (1/2 HP)'s 3381W startup. A soft-starter reduces estimated surge to ~1522W (safe target 1750W with 15% buffer), within the Anker SOLIX C1000's capacity. Running power (1127W, safe target 1297W) is not an issue.
How long will the SOLIX C1000 run a Sump Pump?
With a soft-starter installed, estimated runtime is approximately 0.7 hours, based on 1127W running draw and 1056Wh capacity (70% usable). Without a soft-starter, the Sump Pump (1/2 HP)'s 3381W startup surge exceeds the SOLIX C1000's 2400W surge capacity and the device will not start.
Storm Safety: Since the Sump Pump (1/2 HP) is critical for preventing flooding, we recommend testing this setup specifically before the storm season. Ensure the SOLIX C1000 is fully charged to 100% as storms approach.
