Google "geothermal cooling" (or heating). I think that's what he means.
Both are 48v units. Super powerful.
No way!! I was told I need it for this environment. Dang it. What do you prefer instead?So cool! I would reconsider the visquine. Google it, based on your climate. Might be too late, but it's not a big deal either way. Very happy for this thread! ??
I was thinking rock wool insulation since it prevents fire from spreading. I don't know how useful it is to contain a fire in a shed that is going to burn anyway, but I'm just so used to installing rock wool everywhere that I use it everywhere anyway.Are you putting insulation in the shed? Some decent batts on the underside of the roof will certainly help keep the temp down when the sun is beating down.
I like the idea of a freestanding shed so it doesn't burn the house down. I agree with Will there. In my case, I would build it out of concrete, because we have other things that could catch fire around here, and I have been building concrete forms for years for work. But what I agree with you about is having the sloping roof toward where the solar panels go, all toward sun. However, I don't know what regulatory restrictions are there for solar panels mounted that way, i.e., covering the whole shed's roof. I play with the idea of building piers to move the four corners of a large panel of panels up and down to orient them at the sun all day, so maybe that would be different?Wouldn't a lean-to roof be better for solar?
I skimmed your post and thought you were recommending turning it into a refrigerator. I realize now that's not what you said. But here's how I replied when I still thought that, and it has some long references:Factor in 8 feet high and you have about 500 cubic feet. A 5000 BTU air conditioner will cool that to where you can keep vegetables in there and they won't spoil. That is about 1/3 the size of an average living room, and a 5000 BTU cools a living room well. My little trailer has AC in it as a STANDARD included item! It's 121 cubic feet and it has a 5000 BTU AC in it. As I am out there working on the trailer I have never had the Ac above 1 or 2!
He's fine for cooling. As smart as this kid is, he knows what he's doing.

As a bit of colour, a lot of older of the houses here ( tropical east coast of australia ) have no insulation of any kind in the walls. Outside wall is a sheet of fibro (asbestos based sheeting), inside wall is a sheet of burnie board, a brown composite fibre board that warps at the slightest hint of water, a 10cm unsealed void between the two.
It's not at all unusual to see outside walls sweating during humid nights if the aircon is belting away inside. Despite that the burnie board doesn't warp and having seen inside the walls of enough renovations there isn't any water damage to speak of, at least not from the aircon condensing water out of the air. Looks like letting things dry out is a better approach?
Will very cool set-up. I am designing something very similar currently using the LV5048 as well, Post here: http://www.diysolarforum.com/index....00ah-lithium-iron-phosphate-battery-pack.509/ but I have a lot of indecision regarding my battery bank and to parallel first or series first, etc. What size LIFEP04 cells are those? And what is that BMS? I was thinking of using a DALY 16s 200AMP but I would love to know what yours is there. I am really excited to see what you end up doing with this project. Some insight on split phase would be useful as well. Keep up the great work!Insulating the shed and adding inverters
Batteries have cold temp protection and heater pad system. Need to add converters and outlets next. And ocpd and array. Lots of work to do.View attachment 869
I dont use it at all, but this is a short read that explains it well :
What Happens When You Put a Plastic Vapor Barrier in Your Wall? - Energy Vanguard
A lot of people have heard advice about vapor barriers and vapor retarders. Many of them have walked away confused. A big part of the problem, I think, is that they’ve been told what to do—”Put it on the warm-in-winter…www.energyvanguard.com
It rarely, and I mean RARELY gets humid in Las Vegas.So according to that, the problem is when there is warm humid air outside, and the inside temp is air-conditioned below the dew point. Is it ever humid in Las Vegas?
