How Long Will the Goal Zero Yeti 1500X Run a Window AC (8,000 BTU)?

Updated 2026-10-17 · Yes

About 2.6 hours. The Goal Zero Yeti 1500X stores 1516Wh, and a window AC (8,000 BTU) averages about 490W because it cycles on roughly 70% of the time. That covers about 33% of a typical 8-hour day.

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’t fully keep up. A window AC (8,000 BTU) uses about 3.9 kWh a day at 8 hours of use, more than the Goal Zero Yeti 1500X’s best-case solar harvest. Solar will stretch the runtime but not sustain it.

Tips

  • Mid-size window units need a stout inverter to survive the compressor start.
  • You’ll still have about 1300W 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.
