Solar Shed: Running a Cheap Air Conditioner

[@WillProwse]

Quick corrections and response to comments for this video: -Standby consumption of Giandel 2000W 24V Inverter actually fluctuates between 6-24 watts. I calibrated my meter and tested .62A at 24V. Some viewers stated .8-1A. Lowest I have measured was .28A. -If you click on my product links and the product is not present, it is out of stock. This happens a lot. -No, I am not using the bluetti indefinitely to power the air conditioner. It was for energy audit reasons only (as mentioned in the video), and because I did not want to add a LVD (giandel lvd is too low for lifepo4). I understand the efficiency losses of this setup, and that's ok. I have multiple videos showing how to use buck/boost converters for directly powering AC supplied appliances, and I understand converter efficiency very well. When I was 15 I soldered my DIY power supplies direct to the rectifier diodes of various products after I discovered the voltage they operated at. This was 15 years ago. This is not "new" to me. I think people forget that I lived off-grid w/ solar for 9.5 years, and before that I was building circuits from scratch for my robotics projects. I did BEAM robotics and servo control for animatronics mainly. Some robotic arms with linear actuators. Also, long range sailplanes/race drones. I may look young, but I have built a lot of stuff. I don't think people realize that sometimes. ~~~~~~~~~~~~~~~~~~~~~~~~~~~ Does off-grid solar confuse you?

Could this set up work on a boat using a 5k-6k wall ac unit?

[@JS-vx1nx]

I am not looking down on you but your viewers watching this will not be sufficiently reminded of a air conditioner being a heat pump and pumping Heat is inefficient unless you have some place cool to pump it. In fact some places are too hot to pump the Heat when do you need to pump at the most. But it's very routine for people to ignore the efficiency boost if pumping prior to the hottest hours. Many many businesses run their air conditioners during those hours even though they use extremely expensive electricity and do not provide any cooling beyond the draft. That is the coils are dry on the indoor evaporator coil. That coil is too warm to condense any of the humidity and it often is warmer than the air. This situation should be address by the electric utilities but they make lots of money running air conditioners continuously despite them having an illegal efficiency level. There are many solutions to this problem as you are well aware of. I think the main thing here is that you're using the air conditioner as a token load to demonstrate your off-grid solar system. I don't know if you agree but saying it that way might help us better understand what's going on here. What lots of insulation does is it allows you to precool and then when electricity gets very expensive and the btu of the air conditioner is at its lowest level you can just turn it off. The buffer that you created will let you Coast until the btu to Watts consumed gets back to a respectable level. One of the ways of helping the insulation is the add lots of thermal Mass. Right now I'm trying to keep some peas alive. Peas are very sensitive to heat so I'm growing them in an ice chest and open top ice chest filled with water below the bottom of the pot so that the evaporation chose the water and the insulated sides prevent heat from getting in that way it's amazing how cold the water stays play it's going to be in the mid-90s today so we'll see if the pea plants continue to flower!

[@WillProwse]

And so far it's working! It was 87 degrees 2 days ago, and 2.1kWh powered it just fine. I am going to continue doing my energy audit in the following weeks, but this little ac cools down the shed and my batteries in minutes. And no, I will not keep the bluetti connected indefinitely. Absolutely not! It was an easy way to avoid adding LVD for the giandel while doing energy audit. This AC is very loud and there are more efficient options. But I have a TON of solar, and I am never in the shed, so this works perfect! If you want low standby consumption, buy an energy star ac. You can go to any local store and buy a 6000 btu air conditioner and it will have nearly the same efficiency as this one. I bought mine on sale because it is last years model. I just bought more insulation and will add it today. The roof is covered in panels which shade the shed. Also, the shed is surrounded by natural shade, so it should stay pretty cool. I probably need to insulate the floor and roof a lot to save energy.

[@acrixiacelestia7689]

Just buy Sonoff TH16 (16A) if u want to monitor temp in ur shed. its very easy to use. btw not to mention then u can sync ur smart plug.

[@DCGULL01]

Will- no one cares about how loud the AC is, but- glad you are doing an energy audit to determine what it takes to cool the place during those 110 degree days! I'm interested in the Giandel Inverters- so, I'll be reading those pages next. Insulating the floor will be a PITA, but- blocking off acess to the floor should be relatively easy. Walls- are you going to use the Pink Panther stuff, or rigid foam insulation? Just curious- let us know what you come up with! Thanks for keeping us up to date with the solar shed.

[@jamestimmins7305]

A cheap and efficient way to cool a shed is to shade it with a tarp. Set off of the shed by 8 to 10 inches on the southern side with a 6 inch air gap on the bottom. You can also use a shade tarp sold at garden supply warehouses with the same air gap on the bottom.

You must live in the North. In Texas, even in the shade that shed would be burning up inside.

[@Almatt-qh5zu]

This is PERFECT info for what I've been looking for. So many have built out a cargo style trailer for overlanding or camping. But the trailers (dedicated production or home built) have varying degrees of insulation. I"ve been hesitant to buy even a small camper without figuring out how to run some type of small AC on either 12 or 120 volts. this vid along with a full time nomad camper that runs a 120v 5K BTU AC on about 1K of PV. Excellent info!

[@Koala63211]

I follow a lot of cruising yachts and catamaran sites. One of their biggest problems is cooling the boat at sea or at anchor without running their engines to generate power. I've always thought that there must be some way you can generate enough power from solar to do that. It looks like you are on the right track Will. Good for you, and if you do happen to perfect what you are trying to do, please make sure you take out a patent on it to protect your future life. Well done young man.

[@Gordon013]

I'm sure someone has already said it but many window AC now have WiFi built in so you can check it anytime from anywhere. You can also configure schedules and have it set to turn on and off depending on temperature. You can even check the temperature when it is off to determine if you want to turn it on or not. Keep up the great work. I'm looking at possibly adding solar and backup battery to my house and an RV one of these years. Just starting my research into everything and your knowledge helps a lot.

@@WillProwse I just picked up ( 2 ) used Sharp 175 watt Panels for $50.00 ea. Tested @ 44.3volts. Now just waiting for the clouds and rain to go away. This 350 watts will be added to the 275 watts I currently have in my Truck Camper powering ( 2 ) 200Ah AGM Batteries. Next up is adding 1 more 200Ah AGM Battery. Is 625 watts of Solar a good match for 600Ah of Battery only using a 1000 watt Sine Wave inverter for just a laptop, 32"HDTV, and DVD Player , 3 LED lights, and Phone charging.?

[@silvy7394]

Crazy thing I actually just got done adding another panel to my small solar array and re-building the rails.

[@immeohmyoh]

Gerald you've got more Ah than you need for the little 1000watt inverter, but less panels than you could use to recharge those big 600Ah, if you pulled heavier loads. Maybe you could build a hot-tub or kick amplified sound system, or start crunching bitcoin to generate some load.

[@robormiston2841]

Hey Pops Old Boats. Do you build boats? Because I do and it would be cool to meet others that do? I want to run my boats on solar power. I have a 21 ft. tunnel hull that will go over 100 mph with ease with a 260 h.p Mercury 2 stroke outboard motor. I wonder what it could do with electric power. The boat was built for speed. I designed and built it and it is a solid performer outperforming some of the best boats out there. Because I took all the best attributes from the top boats and added them together to make this boat. It was originally a Champ boat in Italy at 17 ft 6 inches that ran 130 mph untill Al Mourno flipped it at 130 mph and it landed upside down pushing the motor, and cutting the boat in half almost gutting poor Al. " He said the boat split in half and the motor pushed him out! " Al Mourno. A guy named Sid Bass lived down the road from us and built his own complete motors and cut down legs to race form. My dad worked for George Barris Custom Rods and we started Hurricane Performance Tunnel Hulls in the 80's because he was an expert fiberglass dude. He fixed Corvettes, and eventually owned his own Custom Auto Body shop. Ormiston Motors in Bremerton Washington. We then build custom rods, chopped tops, channels cars etc. Then we got into boats deeper lol. Made our own designs and nailed it! They outperformed almost every boat on the market at the time. No one knew what they were. It was like selling a Lamborghini without a test drive. We were 20+ years ahead of the game. Now today they are the most fuel efficient boats on the market with the fastest top speeds available. Now pops has passed on and it's just me and my Covid mask. Lol I. I have the knowledge, the skill, the desire, I even have a 2800 sq.ft shop. But not anyone that speaks my language lol.

Hi Will . I use a wifi plug for my air conditioner . It has both timer and countdown programs, built into the smart plug app. . I use the timer to turn a/c on and off. 0 watts stand by (plugged into ac outlet. 12:00 on ,1:00 off etc... If you use a countdown you have to create many on / off times ...ie... 30 min. On , 60 min. off ,90 min. on etc The problem is you need to restart each timer, everytime that you want it to go through the cycle. If you dont , it won't go on or off .

[@richhagenchicago]

I have intermittently run an AC unit from a Trace SW4048 inverter for years in the summer. I use a relay to turn on the power to the AC as a dump load when I have excess power. I think that if you have adequate space for panels, solar AC is smart. You basically need it most when you have excess power. Panels remain very cheap if you know how to do the wiring. I do not have batteries on that system, it is about a kilowatt hour of ultracapacitor storage which basically acts as a buffer with loads switching from mains to inverter or turning on and off other loads such as supplemental water pre-heating, space heating or AC simply based upon the banks voltage. Has worked reliably for years.

As one point to consider, there must be a fast growing indigenous tree or bush in the Nevada area that you could plant to shade the shed naturally. A plant that grows with little water and thrives in the heat to offer shade.

[@bentnickel7487]

The Tipu tree grows in your area, up to 40 feet tall and should provide great shade to cool the shed naturally. Add under roof insulation and your batteries should be fine.

[@ReflectedMiles]

@@bentnickel7487 So this shade would only be present to the shed itself when needed and not to the solar panels? I want to see some kind of technical rundown on how this 40-foot quantum shade works.

[@bentnickel7487]

He can't have tree shade if he leaves the panels in place. He's not living in an RV anymore, so the panels can be relocated to a place that's advantageous for optimum solar. Cooling the shed starts with natural shade and graduates to under roof and wall insulation.

[@lloydprunier4415]

Good luck with that A/C unit. I bought a 8,000BTU model built in Dec. 2018. They were on sale and I was interested because it had WiFi and remote control unit. The first one I brought home and installed sounded fine, but it was a cool day and I thought it was working. As soon as we had a warm day I realized it wasn't cooling. The compressor was running, but no cooling? I took it back and gambled on another of the same model. Checked it before installing and it worked. Put in my window and thought everything was okay. Next day I tried the remote control and it only works if it wants too! Checked battery and watched the remote light with my phone camera and it is sending signals, but not getting consistent control. Next I went through the steps in the instructions and tried the phone app and WiFI. Should have known from the reviews for the phone app that I was screwed. Only thing I haven't tried to get the WiFi to connect is moving my router. Think the A/C module only works on 2.4Ghz? The thermostat isn't very smart either. It's almost like it just works off a random timer and doesn't care what the temp is. Last time I will buy this brand.

[@terrybecker1314]

I agree, like many Vids, lots of talk and little info. 5000 btu A.C. window unit: run power = ~ 500 watts starting surge = ~ 1000 watts SO... Solar panels = at least 500 watts Start surge can be done with car battery charged by solar panels. ( battery only needed to get A.C. unit running = "start surge" ) 1 battery can be used to start many A.C. units. But a 500 + watt solar panel is needed for each A.C. unit. A 500 + watt power inverter ( 12 volt dc to 120 volt ac ) is needed for each solar panel / A.C. unit And a solar panel set to charge the surge startup battery. Q: How ya gonna run it at night? But killing just the daytime A.C. costs may be worth the effort.

It took some fine tuning, but it works GREAT and only uses a tiny amount of power!

Shading makes a HUGE difference. Also you could probably get away with a swamp cooler in Vegas with the low humidity, which would just need power for the blower motor and the small pump motor.

[@edbenson98]

Insulate the shed and paint the outside white to reflect the sun! Great video!

[@georgefenrich4119]

Do we think he should add REFLECTIX to the outside walls?

[@michaelglenning5107]

For solar powered AC/HP DIY MrCool is a good choice. Only draws 2.1 amp! It uses DC Inverter technology. A less best choice is the new DAIKEN u-shaped window unit, also a DC Inverter based technology unit.

[@bigtimepimpin666]

I cant understand what you're saying. But i understand that magical box in the wall makes cool... that's awesome!

[@theMekanik]

Your shed isn’t moving and it small like you said so cutting a hole in the wall is a good route to go and using a window unit as a permanent solution is perfect 👌🏻

[@Stevenowski]

To get better heat transfer from that little tiny window shaker as they are called, put it on the side in the shade. Every bit helps!

[@obviouslytwo4u]

1-minute into the video I could tell this guy knows his stuff so I subscribe!.

[@patcellucci3431]

Answer to all electrical issues: "...add another solar panel". Lol. When are you going to go underground and pour a concrete bunker? Just kidding..maybe? Keep up the great work. You are very factual and objective. Love that in a youtuber.

[@carldawson5069]

FYI, when watching the detail energy usage, you may notice AC efficiency drops when it is very hot outside. All ACs lose capacity at high outdoor temps because it requires more energy to compess refrigerant to a liquid and the liquid has a higher temperature (part of liquid flashes to cool the hot liquid to normal). If your are watching the inside half, some days the cold discharge air is warmer for the same room temperature. The BTUs cooled is sensible heat (a.k.a. 72° cubic feet of air moved) PLUS latent heat (amount of moisture in air removed a.k.a. grains of water/relative humidity % or wet bulb temperature difference). If you boil noodles, the AC must remove the sensible heat (from the hot plate) and latent (from the latin word for hidden) heat when the steam is condensed into water. This can be 1/3 of the energy used So if the AC numbers don't added up like yesterday (change # of cycles on/off), the weather or a door left open, probably chaged a little of the degress and/or humidity.

[@ruftime]

I agree! Mini splits are great for many applications, but not all😎

[@5037ZING]

Great low tech planning. I will be helped alot for planning my little 40 m2 holiday house in Thailand.

[@workinghands1805]

Love it! My wife was laughing saying that’s totally you 👀😂 with the camera and the thermometer

[@ronstefanelli]

Living in Tucson in a small vintage trailer I have found that with a window a/c there is another variable to consider. The temperature that The a/c is able to maintain is a function of the outside temperature . In other words my 5500btu a/c can only maintain a temperature difference between outside and inside air of about 25 degrees and as the outside air surpasses 100 degrees that differential reduces so that a typical summer temperature of 105 to 112 the difference is only 15 degrees. That means that my inside temperature is around 90 degrees. That is pretty warm even in a “dry heat”. I do have access to grid power and my results are identical. My trailer is less than 100 sq ft..

[@georgefenrich4119]

Can you build a Carport / SHADE? Is your AC on the (LOL in AZ) Shady side? can you Shade the AC?

[@ronstefanelli]

George Fenrich Shading it doesn't help much, maybe a degree or two. Larger btu a/c 's have a larger temp difference, I think, and that's what I'm going to try next. It would help if an hvac guy would weigh in on this. I should probably go with a mini split.

[@chuckhursch5374]

I have a 10’x12’ shed. I may put an air conditioner in that, or a heat pump, and you’re getting me to think I might try powering it off of solar 👍🏻

[@IllumTheMessage]

Do you have a device that can track shed temp every hour our something? Would love to see a graph of shed temp to outside temp to power used. Thanks!

[@WillProwse]

Oh that would be fun!!

[@AnthonyGoodley]

I'm sure that could be done easily with an Arduino and a temperature sensor.

[@marekbasinski4386]

The sonoff temp relay works great. Can set temp range and timer

[@zaibervaireus]

Temperature sensors are common in home automation systems. You can get a nice cheap Home Automation server running in your house on a Raspberry Pi and program it as you wish easily.

[@jonhan6554]

[@keithcarpenter9938]

Thanks for your vids dude. Recently I was studying marine electronics over at Pacific Yacht Systems and I learned that my 2 6v interstate lead acids should be charged at a rate of 50 amps. That's why my rv came with a 50 amp charger. That's a lot less than the maybe 20 amps I get from my solar. That is hard on my batteries because they need the 50 amps to de sulfate. I don't think that many of us small time folks understand this. I'm currently going to upgrade to a 100/50 Victron and am looking for 700 watts of 72 cell panels. There are some used ones on ebay and I thought that could be a good review from you on those panels. Sadly they have to have a pallet so shipping is expensive. I'm thinking of just getting 10 and reselling what I don't need. Used panels vs new is a good subject. If somebody out there in the north bay area of Ca wants to split a pallet of ten or needed 3 or 4 that could be cool.

[@williepughiii777]

Finally someone's listening somebody's listening she got power but you got power but you got converting you know if our so has you hook everything up together after a while you save more power but once you get the charging you know the power that you use while you're charging is drop down to a minimum the more battery power sometimes the better but as you get the ac-dc converters while you're charging the power needed inside as you know left to a minimum but at the same time you don't have to worry about what you need cuz you got one two three four different type of conversions maybe five or six I think I heard him say I know for four or five different types of conversions that does not only regulate but monitor the output but at the same time if you got enough power up there on top on the shed then you should be pulling in at least 500w you know worth of conversion into the yeti so it shouldn't really take that long specially you know what everything you have in there but if you get enough solar power on walking in on it's like having a Transformer f*** having a Transformer you go from 120 to 220 it's not going to overdo it 220 going into it and I'll save you a whole bunch of time but at the same time does do you have the circuit power let's stay inside the yeti to handle 120 to 220 you know potentially power going in but power going out

[@Stubones999]

You could use Yolink temperature sensors and power plug to use your computer to monitor the temperature of the shed, and control the power switch. They use LoRa radio so can be hundreds of feet from the hub and your house.

[@cheesewizard1306]

Nice. Thats one thing i was planning to do now that i have my Lifepo4 battery built. Ive had enough solar to run a/c for a few years, but, i was always afraid that clouds would ruin my old lead batteries. Also, i like my Cotek 48v 1200 watt inventer. Very low power consumption, has lasted 5 years, now. Keep up the good work.

[@telocity]

If it is a small stand alone shed, might consider covering it with a cheap tarp (spacers for airflow, don't want it touching the shed to much) to keep the sun off it. Makes a big difference for temp.

[@jondavidmcnabb]

Excellent video Will, to many folks throw cost aside when doing solar or HVAC

It's a rare situation, when sun is cooling instead of heating.

[@yarpos]

pretty common really in hot climates , and good mix that keeps the summer bills down

[@anonymouswhite7957]

Ryan Crisp We call it cooling for object that gets its thermal energy transferred, and heating for objects that received thermal energy. Ever increasing entropy and energy moving around doesn’t make it less real. Also we can refer to the heat death theory (when entropy achieve it’s maximum level) as cooling since energy gets more disordered and dispersed

[@michaelsinaloense6449]

Well stated!

[@skidmark7845]

If I’m right, old refrigerators ran on the principal of heating up ammonia, which somehow was converted into a cooling effect. If this is true, could you have the core that houses the ammonia in direct sunlight and amplify it with a sort of magnifying glass to increase the suns effects and uses it to generate a cooling effect such as an air conditioner puts out and possibly split it into a refrigerator also. Just a brain fart.

[@Sasquatcho70278]

I live in vegas also and have a 8300w system on my flat roof . It’s exiting to learn about solar

[@nomadicsporadic3836]

Awesome video will, yeah I have a window AC unit in my van, I can run it off my solar , shore power or generator. Keep up the good work...

[@hugoponce69]

Getting ready for the hot weather, hopefully that works for you.

[@melindadoennig7799]

I love this young man's brilliant videos! Am learning so dang much about solar. Thank you!

[@BraveRock]

The Wemo insight is a WiFi switch with built in monitoring. Also thinkeco smart ac is also a WiFi switch with monitoring and a temperature sensing remote. Check them out if that sounds useful!

[@WillProwse]

Smart idea!!

[@ThierryC2373]

To improve energy efficiency, you can also improve the insulation in the shed!!

[@MrTubeman123456]

I didn't hear you say how many watts in panels you have but it's a help thank you keep learning.

[@kevinrowbotham545]

Awesome! AC for the shed Will! Waiting for Amazon to ship the rest of my first solar project along with a copy of your book. Enjoy your straight talking style of videos. Thanks for sharing.

[@atomicinv2]

You use a Tado wifi ac controller to turn on and off the ac unit (assuming it has IR receiver) that would also mean that you would have cloud based control and temperature logging, the later meaning you wouldn't need the big temperature gauge on the wall

[@mishayaros]

Nice videos! I now realize I need to pay you to help me with my campers solar! It is above my head! Your videos are the best I always tel people about your Chanel

[@timothyhaycraft2807]

Mr. Prowse, I am in complete awe of your technical prowess, finding your knowledge of solar unparalleled. As an afishionado of all things solar power I'm prayerfully hoping to beg your knowledgeable assistance, I am trying to formulate an installation plan for a sailboat. I have devoured data on the subject provided by you and other contributors, albeit I humbly confess that I am not comprehending the information. It being far to steep a learning curve for my meager understanding, in order to glean a practical sense of the subject I must defer to those like yourself. Might there be off the shelf pre-designed kits available, a sort of modularized plug-and-play system needing only to be assembled. I have attempted to find answers through internet queries, yet without having an intuitive knowledge of the subject it is oftentimes difficult to identify search terms. I do understand that you're a very busy man without the luxury of time, but if you could at least steer me in the right direction I would be in your debt. I am hoping to have a self sustaining system, coupling a wind generator' solar panels as well as a 5KW diesel generator. A lot of my confusion lies in the configuration, be it a 12/24/48 volt assembly for the most desirable efficiency. I simply lack the ability to even visualize these concepts. At any rate I would like to thank you for taking the time to read this lengthy request, I would be wholly without a doubt indebted to you for any assistance in this matter.

[@Roobah]

That seems to be the same AC unit I got for my van. Also has a soft-start built in. Love it.

[@saadomar1101]

really that's good,, how much would it take to start then?

[@michaelc2644]

We haven't heard from you in a while - hope you are safe and healthy!

[@billblomgren9618]

My battery shed will require an air conditioner and heater. We don't get TONS of freezing weather.. but do get a bunch of high temperatures. A window AC would be great to keep things happy during the summer.

[@stephrs1754]

Yay! Looking forward to updates in the heat of summer!

[@msnpassjan2004]

This is an awesome option to at least have one room in the house with air conditioning if the power goes out.

[@bradfordpalmer2298]

One good thing about being in Lss Vegas, no humidity. It takes lots power to remove the water from the air.

[@knowyourouts3466]

Will, some quick feedback. The only thing stopping me from taking the plunge is I haven't seen any material yet on how not to electrocute myself. Seriously this is the only thing stopping me. Figured I am not alone. Maybe a quick video on solar panel safety and best practices can put those fears to rest. I can't be the only one held back by this simple fear. You have laid out the technicals perfectly....maybe one video on how not to kill ourselves. Thanks Will.

[@kurtzxcvb3481]

For your attic you should use radiant barrier with proper ventilation for your walls I would use rockwool

[@corn_fed_ls4920]

Add some Roxul rock wool insulation, fire resistant and very efficent. You don't need an attic, just insulate under the roof.

[@williamhustonrn6160]

Will, look into Home Assistant Automation, I have dived really deep into this software the last few years, I installed ac relay boards with temp sensors on my window units, so they smart control the a/c via my setting, I have it setup to come on only at set critical temperatures, then turn on when I'm home to "at home" settings based on geoloaction detection of my cell phone. I also use this automation system for my hydroponics garden in my greenhouse, I have probes detecting the water ph, calcium, magnesium and such levels and autocorrects to keep them within a set range of variables I have programmed by adding specific ingredients as required, also reduced my fertilizer expense by detecting how little of ingredients is actually needed to keep plants happily growing. It has been a game-changer on taking a lot of the hard work out of getting my stuff to function perfectly. It just works so well... I feel you could implement this into your solar shed and automate things.

[@ToolsElectroDIY]

Looking forward to a tour of your shed!

[@JGoodwin]

"Didn't want to spend that much on a mini split, so I got this one for $200-$300" "Oh, but I hooked it to this portable power station" Clicks link for power station - only $2k

[@kimmer6]

I'm the almost 70 version of Will. I spent nearly $25K on inverters, 1200 AH of LiFeP04 batteries, transfer switch, wires, fuses, etc.....just to keep my fridge and clock running when the utility shuts down. Added bonus: We lost power one rainy evening in November for over 4 hours. I'm the only guy for miles who cooked a turkey on batteries.

That was my reaction, too 😳
