Air conditioning on solar
So today I put together the three solar systems on the 8-D, hooked up the PowerJack inverter and then the 5000 BTU air conditioner. The Air conditioner is a Frigidaire unit that uses 446w/ 3.9a @120v....

Luckily we usually don't deal with record setting temperatures up there. Denver, for being a mile high gets hotter than all get out every year. Those years with records up there had records down here too and it was miserable. I know, I worked in it for years. Grew up in farm country and spent many days cooking until I got a job as a stock boy at 14. House didn't have air, school didn't have air, not even the car, you never saw a kid get to work early as often as I did.

Let me explain the difference in Mono vs poly in a different way.
Poly lose amps when the light drops like a dimmer switch all the way down to the light you get just before the sun comes up. My 230w will wake up the controller and put out .47a.
Monos have a different switch. It goes bright light, anything but bright light and off. On my 245w those numbers are 17a in bright light, 2.38a in anything else to a point and off. Off happens at higher light levels than you think too. I would see 5-8a off of the poly in the conditions that put the monos to sleep.
There are a lot of amps in those clouds, enough to keep us off the generator if we are not pigs about it. Being able to milk 4a by pointing the 230w poly at the brightest spot in the clouds meant the trailers grp 27 lasted through two nights in the 20's with a cold cloudy day in between. Three panels and I'd get 12a, I can do pretty good with 12a. Now remember that the mono's would be asleep vs that 12a and you see why I'm selling mine in favor of polys.
