Recharging with solar
The Jackery Explorer 240 v2 accepts up to 100W of solar input. In real conditions that harvests about 375Wh on a sunny day (5 peak-sun hours).
Solar can’t fully keep up. An aquarium heater (100W) uses about 960Wh a day at 24 hours of use, more than the Jackery Explorer 240 v2’s best-case solar harvest. Solar will stretch the runtime but not sustain it.
Tips
- Aquarium heaters cycle with their thermostat. Add an air pump (5–10W) to keep fish oxygenated during an outage.
- You’ll still have about 200W of AC capacity left for other devices at the same time, though they’ll share the same battery.
- The Jackery Explorer 240 v2 uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.
