Window AC hours on the S5000

|---|---|---|
| 5,000 BTU window AC (Frigidaire) | 450 W | 9.5 h |

Wh × 0.85 ÷ (watts + the station’s own draw, where the maker lists it). The S5000 goes on sale Oct 27.
Hours are nonstop; the compressor cycles off once the room is cool, so real hours are longer.
Can the S5000 start it?
We plan for a start of about 4× running watts, a figure from a generator maker (Polaris). Inverter ACs start more gently (Berkeley Lab). The S5000 has a 8,000 W surge. 5,000 BTU window AC: covers it; 8,000 BTU window AC: covers it.
How much an hour takes
An hour of a 5,000 BTU window AC running nonstop uses about 450 Wh, about 11% of the S5000’s usable 4,270 Wh. At its 3,000 W solar input and our 75% assumption, strong sun puts about 2,250 Wh an hour back into the battery.
AC manuals commonly say to plug into a wall outlet and not to use an extension cord; check yours first.
