Recharging with solar
The Goal Zero Yeti 1500X accepts up to 600W of solar input. In real conditions that harvests about 2.3 kWh on a sunny day (5 peak-sun hours), or about 750Wh with one 200W panel.
Solar can keep up. A humidifier uses about 320Wh a day at 8 hours of use, so with enough panels and good sun the Goal Zero Yeti 1500X can run it indefinitely.
Tips
- Ultrasonic humidifiers use 25–50W; warm-mist models use far more (200W+).
- You’ll still have about 1960W of AC capacity left for other devices at the same time, though they’ll share the same battery.
- The Goal Zero Yeti 1500X uses NMC cells, which are lighter but rated for fewer cycles (typically 500–800) than newer LFP models.
