People talk like it's hard :elkgrin:
It's interesting to see the reactions of people to the entire concept. I'm pretty certain that most think this is a 24/7 plan to run a/c... no. Of course, most of the harshest critics don't read past the first period so they're blissfully unaware of what happened next. So let's recap
I have a Renogy 200 watt pair of solar panels on the roof. The a/c (as I'll demonstrate in a moment) draws 1400 watts. There is NO chance you can run a/c off this small of a solar system.... except. I don't need a/c 24/7. Let's recap. My wife does K9 Search and Rescue with two terrorists.... errr.. bloodhounds (the term is interchangeable). She leaves to go to a mission in the dead of night for missions in Western Washington. Traveling to and from the mission - the truck has awesome a/c so rooftop a/c isn't needed. When it is needed is that 3-6 pm time frame when it gets hot. Before and after fans are more then adequate (and the fan draws 160 watts on high). We have solar blankets (reflects the sun), 3 sided awning, and the dogs can handle some heat.... okay... with me so far? good. I also use the rig for non-mission SAR work - think of it as someone people call for help. The a/c is only needed for short bursts and during camping trips just enough to cool the inside of the rig so that I can sleep in it. I don't do indoors if I go outdoors.
So the requirements are solar for 3 hours that are mitigated by solar and run off 2 - 200 amp-hour batteries. 12*200 = 2400 watts per battery per hour. Between the 2 batteries and 30% draw down, I have 3-4 hours of battery power and maybe another hour if the sun is optimal at full song. Which brings me to the other part. This a/c could easily bring the temp inside down to keep Popsicles cold. So it shouldn't need to run at full song for an hour, further testing will reveal but my bestimate is 5-6 hours of actual run time. This is success because it exceeds what I need it to do. As an aside - the heater was a bad idea, I need a larger inverter to pull that off... don't care, when I go skiing, I can plug in.
so pictures
for those who want a Mach 8 with a heater, this is how it goes in - their instructions are abysmal. This picture is look from the front of the unit towards that back
another view
yes, I ran an extension cord from the unit.... as you cannot clearly see, it's drawing 1400 watts
so to recap, we have battery-powered a/c, water, refrigeration, propane, and soon a stove.... and you wondered why I nodded to the Wanderers....
