The numbers
| Battery capacity | 1536Wh (LFP) |
|---|---|
| Usable energy | 1306Wh (85% via AC outlets) |
| Continuous AC output | 2200W |
| Surge rating | 4400W |
| Window AC (8,000 BTU) running watts | 700W |
| Startup watts | 2000W |
| Average draw | 490W |
| Estimated runtime | 2.7 hours |
| Energy per day of typical use | 3.9 kWh |
1536Wh × 0.85 = 1306Wh usable ÷ 490W average = 2.7 hours

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’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 Pecron E1500LFP’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 1500W 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.

FAQ
Will the Pecron E1500LFP run a window AC (8,000 BTU) overnight?
No. At about 490W average it runs out after 2.7 hours. For a full night you need at least 4700Wh of capacity.
How long does the Pecron E1500LFP take to recharge with solar?
With its maximum 800W of solar input it refills in about 2.6 hours of strong sun. With a single 200W panel, expect about 2 sunny days (10 hours of full sun).
