Recharging with solar
The EcoFlow Delta Pro 3 accepts up to 2600W of solar input. In real conditions that harvests about 9.8 kWh on a sunny day (5 peak-sun hours), or about 750Wh with one 200W panel.
Solar can keep up. A dehumidifier uses about 3.6 kWh a day at 12 hours of use, so with enough panels and good sun the EcoFlow Delta Pro 3 can run it indefinitely.
Tips
- A 50-pint dehumidifier draws about 500W while its compressor runs.
- You’ll still have about 3500W of AC capacity left for other devices at the same time, though they’ll share the same battery.
- The EcoFlow Delta Pro 3 uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.
