Recharging with solar

The Bluetti AC180 accepts up to 500W of solar input. In real conditions that harvests about 1.9 kWh on a sunny day (5 peak-sun hours), or about 750Wh with one 200W panel.

Solar can keep up. A CPAP with humidifier uses about 480Wh a day at 8 hours of use, so with enough panels and good sun the Bluetti AC180 can run it indefinitely.

Tips

  • The heated humidifier roughly doubles a CPAP's power draw. Turning it down or off is the easiest way to get more nights per charge.
  • You’ll still have about 1740W of AC capacity left for other devices at the same time, though they’ll share the same battery.
  • The Bluetti AC180 uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.
