How Long Will the Pecron E1500LFP Run a Window AC (5,000 BTU)?

Updated 2026-10-17 · Yes

About 4.1 hours. The Pecron E1500LFP stores 1536Wh, and a window AC (5,000 BTU) averages about 315W because it cycles on roughly 70% of the time. That covers about 52% of a typical 8-hour day.

Recharging with solar

The Pecron E1500LFP accepts up to 800W of solar input. In real conditions that harvests about 3 kWh on a sunny day (5 peak-sun hours), or about 750Wh with one 200W panel.

Solar can keep up. A window AC (5,000 BTU) uses about 2.5 kWh a day at 8 hours of use, so with enough panels and good sun the Pecron E1500LFP can run it indefinitely.

Tips

  • Small window units draw around 450W while the compressor runs. On hot days it rarely switches off, so expect 60–80% duty.
  • You’ll still have about 1750W of AC capacity left for other devices at the same time, though they’ll share the same battery.
  • The Pecron E1500LFP uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.
