Recharging with solar
The EcoFlow Delta Pro accepts up to 1600W of solar input. In real conditions that harvests about 6 kWh on a sunny day (5 peak-sun hours), or about 750Wh with one 200W panel.
Solar can keep up. A portable air conditioner uses about 5.6 kWh a day at 8 hours of use, so with enough panels and good sun the EcoFlow Delta Pro can run it indefinitely.
Tips
- Portable ACs (10,000 BTU class) are less efficient than window units because they vent hot air through a hose.
- You’ll still have about 2600W of AC capacity left for other devices at the same time, though they’ll share the same battery.
- The EcoFlow Delta Pro uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.
