#1 failure reason
74% of the 66 pairings in this category pass our True Surge protocol (SAFE or TIGHT).
- Highest surge ratio: 3x (Sump Pump (1/2 HP)). Peak power headroom matters more than rated capacity here.
- 11% of failed pairings could be rescued with a soft-start device, which reduces inrush current by ~55%.
What matters in this category
- Sump pumps and furnace blowers spike to 3-5x running watts at startup. A pump running at 800W can surge past 3,000W.
- These devices run for hours or days during outages. Capacity (Wh) matters as much as output (W). Plan for 24-48 hours of runtime.
- Freezers have duty cycles that reduce average draw, but the compressor still surges each time it cycles on.
How to choose for Emergency
Emergency devices have the widest surge-to-running ratio of any category. Focus on surge rating first, capacity second. For furnace blowers, check whether the motor is PSC (high surge) or ECM (low surge). For multi-day outages, solar charging capability becomes essential. If you need to run a sump pump during a storm, you need a station that can handle repeated startup surges, not just one.
Common mistake
Assuming a station that covers running watts will handle startup. A 1,000W station cannot start most sump pumps, even though they only draw 500-800W while running.
