I get 280W solar panel installed on roof with suitable wire to inside. I get 120 amp hour 12V AGM battery. I get one standard charge controller. I get Xantrex 1000 or 2000 watt sinewave inverter. I get short 3' very fat (0g or whatever) cable to connect battery to inverter inside shed. I put CO detector on ceiling (also detects H2, which shouldn't be a problem anyway). I get 5000 BTU air conditioner, rated 5 amps. I know that the "5 amp" motor load is not a difficult load, non-resistive. But shouldn't this setup be able to run it for a few minutes to nearly an hour every week? 5 amps load at 120V A/C means about 50 amp draw from battery. That's a big de-rating from the 2000W resistive capacity of the inverter, and battery should have no problem with that level of draw.
The idea is not that I run A/C all day long every day, but rather I run A/C an hour or less once a week, while getting something out of storage and/or putting something else back in. The rest of the time, during daylight, the battery is slowly recharging.
