Recharging with solar
The Anker SOLIX C800 Plus accepts up to 300W of solar input. In real conditions that harvests about 1.1 kWh on a sunny day (5 peak-sun hours), or about 750Wh with one 200W panel.
Solar can keep up. A box fan uses about 600Wh a day at 8 hours of use, so with enough panels and good sun the Anker SOLIX C800 Plus can run it indefinitely.
Tips
- A 20-inch box fan draws 50–100W depending on speed.
- You’ll still have about 1125W of AC capacity left for other devices at the same time, though they’ll share the same battery.
- The Anker SOLIX C800 Plus uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.
