Window AC hours on the C1000 Gen 2
| Case | Watts | On the C1000 Gen 2 |
|---|---|---|
| 5,000 BTU window AC (Frigidaire) | 450 W | 1.9 h |
| 8,000 BTU window AC (Friedrich) | 661 W | 1.3 h |
Wh × 0.85 ÷ (watts + the station’s own draw, where the maker lists it).
Hours are nonstop; the compressor cycles off once the room is cool, so real hours are longer.
Can the C1000 Gen 2 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 C1000 Gen 2 has a 3,000 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 52% of the C1000 Gen 2’s usable 870 Wh. At its 600 W solar input and our 75% assumption, strong sun puts about 450 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.
