Recharging with solar
The DJI Power 500 accepts up to 300W of solar input. In real conditions that harvests about 1.1 kWh on a sunny day (5 peak-sun hours), or about 750Wh with one 200W panel.
Tips
- A 20V 5Ah pack (DeWalt, Milwaukee, Makita) stores about 100Wh.
- The DJI Power 500 uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.
