Oh and by the way we have the only adjustable EER for an air conditioner on the planet. An EER can only be determined while using grid power, for instance the day I made this video I ran the unit until about 3:30 in the afternoon completly off the sun but I started to lose the solar so I plugged the unit into the wall while I was collecting solar still having no batteries in the unit. Now I have a 1080 watts of solar panels outside but you know as well as i do that I am not getting every single watt, At 3:30 in the afternoon I am starting to drop out slowly so by plugging the unit into ac power I only use what I am not getting from the panels on that day at that time i was deficient by 180 watts so here is where the adjustable EER comes to life. 13,500 BTU's /180= an eer of 75 remember eer can only be calculated to grid power. So in total I was using only 1.5 amps @ 120v Is that not cool or what!

We have tested the air con at a 100% duty cycle. Remember we do have an on board battery bank on the unit, it will run all day long if there is clouds or a shading effect the unit will take what it is not getting from the sun from the batterys, when there is no more sun then the unit will go to the grid and run off the on board power supply. This air con is prioritized to run on renewable energys first and grid absoluttly last. The sun doesnt shine at night so we recommend a blended system of solar and wind.If you check my web site you will also see that we carry a 500 watt wind turbine and a 2.5 kw turbine.

John: how many hours per day does the AC unit run for on a bright and sunny day?

That is correct, 24vdc@940 watts. No inversion!

John: thanks for the quick reply, it seems like the AC runs from DC power correct? There is no inverter from what I can tell in the video, is that right?

Hi Deep! This unit is 13,500 BTU's so we are about 1500 btu's over a ton with this unit, We can cool 600 sq feet. I am developing a 19,200 BTU unit now which we will be showing soon. And yes it really is the coolest way to go green. Please pass this video around Deep I welcome any questions from you and all.

wow!!! this is really cool. First "true" solar powered air conditioner unit. this is unbelievable! How many tons is this AC unit? How many square feet can the air con. unit cool? this must be a very efficient AC unit.
