Recharging with solar
The EcoFlow Delta 3 Max accepts up to 500W of solar input. In real conditions that harvests about 1.9 kWh on a sunny day (5 peak-sun hours), or about 750Wh with one 200W panel.
Tips
- A DJI Mavic 3 battery is 77Wh; Mini-series batteries are about 30Wh.
- The EcoFlow Delta 3 Max uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.
