Recharging with solar
The Bluetti EB3A accepts up to 200W of solar input. In real conditions that harvests about 750Wh on a sunny day (5 peak-sun hours).
Tips
- A 20V 5Ah pack (DeWalt, Milwaukee, Makita) stores about 100Wh.
- The Bluetti EB3A uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.
