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.
Tips
- Most phones hold 12–19Wh. Charge from a USB port rather than the AC outlet to skip inverter losses.
- 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.
