Recharging with solar

The EcoFlow Delta 3 Max 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 heated mattress pad uses about 432Wh a day at 8 hours of use, so with enough panels and good sun the EcoFlow Delta 3 Max can run it indefinitely.

Tips

  • Queen-size heated pads draw about 90W and cycle once warm.
  • You’ll still have about 2310W of AC capacity left for other devices at the same time, though they’ll share the same battery.
  • The EcoFlow Delta 3 Max uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.
