The numbers
| Battery capacity | 1024Wh (LFP) |
|---|---|
| Usable energy | 870Wh (85% via AC outlets) |
| Continuous AC output | 2000W |
| Surge rating | 3000W |
| Sump pump (1/3 HP) running watts | 800W |
| Startup watts | 2000W |
| Average draw | 200W |
| Estimated runtime | 4.4 hours |
| Energy per day of typical use | 4.8 kWh |
1024Wh × 0.85 = 870Wh usable ÷ 200W average = 4.4 hours

Recharging with solar
The Anker SOLIX C1000 Gen 2 accepts up to 600W of solar input. In real conditions that harvests about 2.3 kWh on a sunny day (5 peak-sun hours), or about 750Wh with one 200W panel.
Solar can’t fully keep up. A sump pump (1/3 HP) uses about 4.8 kWh a day at 24 hours of use, more than the Anker SOLIX C1000 Gen 2’s best-case solar harvest. Solar will stretch the runtime but not sustain it.
Tips
- Sump pumps run in short bursts; how often depends on how much water is coming in. The motor start is the main hurdle.
- You’ll still have about 1200W of AC capacity left for other devices at the same time, though they’ll share the same battery.
- The Anker SOLIX C1000 Gen 2 uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.
