The numbers
| Battery capacity | 3840Wh (LFP) |
|---|---|
| Usable energy | 3264Wh (85% via AC outlets) |
| Continuous AC output | 6000W |
| Surge rating | 9000W |
| Chest freezer running watts | 100W |
| Startup watts | 700W |
| Average draw | 35W |
| Estimated runtime | 3.9 days |
| Energy per day of typical use | 840Wh |
3840Wh × 0.85 = 3264Wh usable ÷ 35W average = 93.3 hours

Recharging with solar
The Anker SOLIX F3800 accepts up to 2400W of solar input. In real conditions that harvests about 9 kWh on a sunny day (5 peak-sun hours), or about 750Wh with one 200W panel.
Solar can keep up. A chest freezer uses about 840Wh a day at 24 hours of use, so with enough panels and good sun the Anker SOLIX F3800 can run it indefinitely.
Tips
- Chest freezers are well insulated, so their compressor runs less than an upright fridge's. Keep the lid closed during an outage.
- You’ll still have about 5900W of AC capacity left for other devices at the same time, though they’ll share the same battery.
- The Anker SOLIX F3800 uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.
