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 Wi-Fi router and modem uses about 480Wh a day at 24 hours of use, so with enough panels and good sun the EcoFlow Delta Pro 3 can run it indefinitely.

Tips

  • Keeping internet up during an outage costs very little power, as long as your ISP's equipment down the street still has power too.
  • Running it from the EcoFlow Delta Pro 3’s DC port instead of the AC outlet avoids inverter losses: about 287Wh more usable energy.
  • 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.
