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 12V camping fan uses about 150Wh a day at 10 hours of use, so with enough panels and good sun the EcoFlow Delta Pro can run it indefinitely.

Tips

  • USB and 12V fans sip power, making them the cheapest way to stay cool off-grid.
  • Running it from the EcoFlow Delta Pro’s DC port instead of the AC outlet avoids inverter losses: about 252Wh more usable energy.
  • The EcoFlow Delta Pro uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.
