IF you would read it, you would find that AC connection is optional.Actually, that is for the AC couples option equipped system.
This will be an all dc 48V unit.

Which is why I said OPTION system...IF you would read it, you would find that AC connection is optional.
We have allot of those little Toshiba 6000 BTU A/C's that you can get from Home Depot // working out of cconex offices
I've seen that exact combo at burning man. except they use gens not solar.
I wish I could cool and de-hu with 6000btu. I have two 13,500 units.
Very interesting point.so it sounds like you have an RV ... for some of the RV's that have two doors .. we take the AC .. put it in the door
Very interesting point.
I currently use one of the all-in-one A/C units in my caravan but it is sooooooooo crap. Because it pulls in air from outside, you only ever get a couple of degrees of cooling in operation. Might have to consider cutting a new hole in my caravan...
so it sounds like you have an RV / foamboard // that little 6000 puts out more cold then the 13500 they have

Hey, this looks super interesting. Did you ever set it up? I'd love to try something like that.Hello,
I picked up a used (barely used) generic brand Mini Split air conditioning system for cheap (1 ton cooling), that takes DC input.
The label on Compressor portion of the Air Conditioning Unit says:
Rated Volatge: DC 48V
Cooling Capacity 12000 (2000-13500) BTU
Rated Input Power (Cooling) 850 (100-13000) W
I have some Kyocera KC158G PV Modules. The specs on these are:
Max Power: 158W
Max Power Voltage: 23.2 Volts
Max Power Current: 6.82 Amps
Open Circuit Voltage: 28.9 Volts
Short-Circuit Current: 7.58 Amps
I’m interesting in powering this unit with the PV modules directly.
It seems like I would have a 2S3P arrangement: 2 in series (23.2VX2=46.4V), and 3 in parallel (850W input power required / (158 W X 2 ) = 2.7)
I realize I'm falling short of the input voltage by 1.6 (48-46.4 ), but I'm guessing that might be negligible as it is 97% (46.4/48) of the input voltage.
Would love to hear your thoughts about this project. I have never hooked up anything solar before, but have a background in EE /physics in college classes with lab work, so understand enough to possibly know if I am going to kill myself, and of coarse the home repair projects wiring things up.
Would love to have your opinions here on this project.
Thanks in advance.
