Yep. Which is why if you notice my parking habits if your ever with me, your going to notice that in certain area's, I'll try and park in shaded area's during the summer, and in known sunny areas in the winter. Especially if your in those sinarios where you need to get frost off your windows and you know you have a little bit of time for the sun to do it's thing before you take off somewhere. Edit: ok, so, while what i said regarding me parking in certain spots is true, sometimes that isn't always practical. I have one of those things that you put in the windshield that i will put there during the summer, and in one perticular parking lot in a perticular area, I was able to park my cars nose east or west depending on the time of the year. Unfortunately, that lot is presumably now a paid parking lot and doesn't allow for overnight parking (although, what i said had not been confirmed with parking enforcement, and, the vehicle's that are parked in the lot seem to still be there in the morning. at least, that's the case right now in late February of 2024).

@@ka7hqp182 Indeed, I feel like more batteries would help a lot. That's the big problem we have in California. We get a shit load of power during the day from the sun. 15 GW. (well, at this very moment, 12.4 GW. Sun is not very high in the sky yet.) But we don't have enough storage to go through the night on batteries. YET. We're working on that. personally I figure we want about 216 GWh of storage, that would output 15 GW for 12 hours. But I believe the current goal is to get to 100 GWh, which would output 15 GW for roughly 7 hours. Which isn't bad. There's a company called hydrostor from Canada, they are building us some facilities that will store power in the form of compressed air. They dig a cavern underground, and put water to maintain the air pressure. It's like pumped storage, but not requiring a naturally occurring geography that's favorable to pumped storage. 🙂 Hydrostor's two facilities will be nowhere near 100 GWh though, we have to keep building more facilities. Of course solar isn't our only source of green power; we also have the world's largest geothermal facilities, which currently output 800 MW but they are being upgraded with some new plants that draw from the same heat source. (there's a huge blob of magma right underneath the north end of the San Francisco Bay. It causes naturally occurring steam underground.) Ultimately with the upgrades, "The Geysers" will output around 1.3 GW, 24/7 (no batteries needed). The other big geothermal source we are working on is the one down by San Diego, by the Salton Sea. Controlled thermal plans to build 1.1 GW of geothermal there. Some of the power will be used to extract lithium the hot brine. They think there is enough to get 300,000 tons of it every year for the next 100 years at least. California also has a lot of hydroelectric power, and we have one nuclear power plant. Unfortunately there are a lot of people not understanding the benefits of nuclear and basically afraid of it, so it's going to close down around 2025. If we get the geothermal fully built in the Salton Sea and Geysers areas though, that will replace nuclear as baseload. (I was a submariner, so I definitely support nuclear power. As the Captain of the USS Nautilus said, it is a "remarkable" form of energy.) 🙂

The window units that Dave (8-bit guy) uses are inverters. I have one too. They're very silent and pretty powerful and they allow a lot more visibility through the window, and allow the window to open and close when they're installed.

Two big things that should be considered before you decide to up your power capabilities. 1: How good is your thermal envelope? you might get significantly more effect if you spend your money DIY or even professionally upgrading your insulation. Air leaks in windows and doors among other places are a huge contributor to heat ingress, the next biggest being heat moving through poorly insulated walls/ceilings/floors. This is probably one big reason you couldn't cool your bedroom to your liking, the window was not sealed and despite having a two hose system it's still likely heat was getting in. 2: Shade shade shade shade shade! That was the whole reason why people planted those trees that are blocking your solar power, but trees aren't the only solution. Hell, even your solar panels could be lowering the heat input through your roof if you give them a nice air gap between them and the roof. This also helps keep them cooler and more effective in power production. And then there's that wall on the side of the house that gets hot, aside from checking/upgrading it's insulation, find yourself some shade net and hang it from your eves or otherwise use it to intercept the sunlight and give your wall a good couple feet of breathing room from the brunt of the sunlight! Bonus: If you can, and your insulation is good enough, get your ACs working overtime early in the morning. The cooler air outside makes them more effective at rejecting heat and more efficient, and you can store energy in the form of an air battery in the temperature difference between inside and outside. The lower the inside temps at the start of the day, the more of a head start your ACs have. This is also a great idea if you have peak and off peak consumption pricing for overall, if you have good enough insulation blasting your AC at night when the power is cheapest will reduce the cooling you need at peak or at least delay your draw.

You can even get solar panels that use unused solar energy that the solar panel can't absorb as electricity and uses it to heat water running through them, which not only boosts the solar cells efficiency but allows warm water with no power or gas in the winter without drawing from batteries

I have similar thoughts; the factory engineer for the central HVAC systems told me that the actual factory cost is 1/20th the cost that is charged by the supply houses.

Advice from Europe: In order to keep heat outside the house in summer and inside the house in winter, I recommend upgrading your windows with roller shutters. A good window can insulate against air (temperature, humidity, noise) but it cannot insulate against the energy of light. Everybody knows how hot an inside floor or a window sill can become when the sun is shining on it through a window. Blocking (and reflecting) the sunlight will help to keep your house cooler and as a result you can reduce the amount of electrical energy needed for air conditioning.

@Dhampy

We like to use window quilts in my part of the US, the cold part of the US. But they work extremely well for keeping heat out as well when backed with white fabric. Combined with modern windows that filter IR and UV, at least until the gas insulations leak out, reducing the amount of overall energy outside of visible spectrums passing through, it works even better. You can also get treatments that reduce visible wavelengths, like polarized films... but then if you wear polarized eye glasses, you may have trouble seeing outside depending on the direction of the polarization in each.

Very entertaining video. One thing you might do (and make a video about it) is to get a professional energy audit, where they use a blower door to do a leak test and use FLIR cameras to find voids in your wall and ceiling insulation. Adding more insulation is usually the best ROI to improve the comfort of the house and reduce your electrical usage. Most older tract houses have pretty poor insulation in the walls and ceilings.

I have one of those 8000 BTU Midea window units. Since getting it, I’ve learned a bit about Midea. The smart bits are actually used by a lot of companies and they allow for LAN based control without the use of cloud if you install the right addon in Home Assistant. Now, yes, the Midea system is going to be way more efficient. A bunch of them will be way more efficient. It’s not because they are window units, per se. It’s because they run variable speed compressors while the majority of central HVAC systems are not variable speed. They’re either on or off. And firing them up is a massive spike in power draw. But in Home Assistant, where I can see charted periods of when the HVAC runs and when the window unit runs, the window unit is almost always in “run mode” while the HVAC cycles when it’s below 100F outside, or just runs at full when above 100F outside. Logging the data in Home Assistant, I find many periods where my window unit is using as little as 100W, but maybe hits up to 400W or so. It’s a 710W unit, but I leave it in eco mode. The room I use it in stays cold. Midea makes mini split systems. They have options for ceiling cartridges and the traditional wall systems.

I use window units. There are advantages and disadvantages, as in anything. (Disclaimer: I am not an electrician or an A/C tech or anything similar. Also, I'm in the US so what I say may not apply to other countries.) Ideally each window unit should have its own separate circuit. If possible, they should be 20A circuits instead of the standard 15A circuits. Having a 20A circuit also gives you more options. You can get a more powerful A/C or even one with a built in heater since both of those will draw more juice than a 15A circuit could safely supply. A 20A outlet (female) will accept a standard 15A plug (male) but not vice versa so you could still use a unit with a normal plug. 20A circuits aren't just a special outlet, they also have more robust wiring and a special breaker. Of course, that's the ideal and most people just plug them into regular outlets. That can overload the circuit. If you plan on changing over, I would have an electrician add a 20A circuit to each room where you plan to add a window unit. At least do it for the larger ones.

He was taking a bit of license with that statement. Deadly heat scenarios always involve a second factor. If you're reasonably healthy, don't get too much direct sun and stay hydrated, there's almost no outdoor temperature high enough to actually kill you. In the case of the A/C quitting, either it's because the space becomes an oven and exceeds what you'd experience outdoors, or he was thinking of examples that involve the elderly or infirm.

Nice video, thanks for taking the time. I have installed 3 mini-splits in the house for a total of 3.25 tons, and have not used the 5 ton central A/C in over a year. I like the fact I can control temps in 3 different zones, and they are super quite. Not to mention the cost savings, and the biggest plus is the fact I can run them on my solar backup power. I'm in West Texas, and Feb 2021 had me focused on having sustainable backup power. I had to use it 6 times since spring do to storms, and substation problems, and so glad I have it.

Central A/C condensers (the 'outside unit') cost quite a bit *because* it's the same as 4 of those 12k units. It has a huge compressor which is packed with copper coils and then it runs the freon up to the attic A-Frame and back down which is more copper tubing. There's also an electric motor for the fan and a radiator, all inside a casing. As for the attic unit, there's the A-frame which gets the cold freon and it likely has a heating element which uses an electric motor on a squirrel cage fan to blow the air into the duct work. The metal casing is insulated so it doesn't form condensation on the outside. The pan you mentioned isn't for emergencies, it's a drain pan as the A-frame forms condensation from the humid house air. There should be a pipe draining somewhere, often outside or into the shower/toilet breather pipe.

This was a wonderful educational video! Thanks for putting the time and effort into making it for us. I live in Central Texas and I know the heat and lack of rain has been brutal in 2023.

Likewise, if there's heavy humidity, it basically becomes a large dehumidifier and focuses on moisture removal first, temperature later.

Awesome work David, really interesting stuff. I get a kick outta this stuff, have a good one bud, I look forward to new videos.

Great video David. I think one of the advantages of the mini split and central AC is that they can also be used to heat during the winter, consuming less power than a space heater for the same amount of heat. These makes them a better choice for solar power.

I think if the refrigerator had been prioritized a bit more it could have sustained itself for a full 24 hours - that's a significant achievement! Furthermore, your studio building seems pretty close to being able to endure a day or more without power. Perhaps a strategic move would be to enhance the solar and battery capacity there to provide a safe haven for your family. Meanwhile, the current setup in the main house can be utilized to maintain temperatures below 95 degrees F (the recommended ambient maximum for refrigerators) ensuring the safety of your food. Echoing some previous comments, given common building practices in recent decades, I'd speculate that enhancing the insulation in your main house might offer the best return on investment. This would reduce the external heat influx, making it more efficient for your house system to maintain desired temperatures.

Insulating your attic is valuable -- but to go along with that, proper attic ventilation is critical. If you vent properly, you can reduce your attic temps to (hopefully) closer to outside ambient, which will reduce the amount of heat your insulation has to resist heat radiating down into your living space. They go hand in hand. If your attic isn't properly vented, all the insulation in the world will not help like you want it to. You can also install radiant reflectors (foil looking things) to help as well. They're all complimentary approaches.

Even the cheaper brands they build have sticker logo pack to pick what brand you want to sell. All the same parts but a Trane costs way more. Once a authorized wholesaler buys the equipment the repair/installing companies or licensed small outfits buy it and mark up the equipment price 300% with labor. Even on parts, a run capacitor for the compressor/fan is a $12 part at the wholesaler to installer and heard some installers charge $100 just for the part not including labor. It is a big rip off starting at the factories, all name brands are bullshat even with appliances. You suppose to have an HVAC license to buy equipment but heard Goodman brand sells to all.

“It seems most of the cost of central A/C is the labor” yes it is. I’m an HV/AC worker, some companies do over charge as happens in an industry. That being said the reason the labor is so high generally has more todo with the labor shortages, difficulty of the job and how much other infrastructure is required. The distance between the outdoor unit and the indoor furnace is usually massive. No one wants to see refrigerate lines so these need to be hidden in a crawl space or attic or at worst close to the wall. Then these lines need to be soldered together (more difficult then copper plumbing) while nitrogen is being ran through the lines. The lines then need to a vacuum and the amount of refrigerate calculated. Then you have to run condensation drain lines and often pumps for said lines. All and all when some one tells you 10k for a system it’s not like their making an absolute killing maybe 10-20% markup, if anything goes wrong that can shrink margins to 5% or less very quickly. Anyways it’s actually a ton of not just labor but skilled labor. Love your vids pls make more

You should consider building a 5+kW battery (store in your garage). There are a ton of videos on KZread on how to do this and you def have the skills to put one together. This way, you will be using all your panels more effectively and able to store enough power in a battery of this size to last you through the night. Also maybe consider using your car batteries for this.

Here in South Africa we have load shedding where we have power outages for sometimes 4 to 6 hours a day spread out through the day.

Another option is using a heaat pump to use the cold "stored" in the underground. In the winter you could use the underground temperature to heat you house.

@@DoomWarriorX you cannot keep the house cool without AC, once the heat is in the isolation will make it stick longer, but the same applies for cold, but it probably will help to add another 5-6 hours to the emergency bridge time in this case. Have in mind that in Europe we use mostly solid material for house building which also acts as a heat/cold store, so you can prolong whatever temperatures you have for longer periods of time with the stone like materials as well, wood does not have this, it reacts rather swiftly to temperature changes. So even with isolation you wont get the same effectiveness on a wood building as you have with stone like materials. The next issue is the window, proper isolation means you need a completely different window design with multi layered windows and foam or rubber buffered connection points, which "shoots" the window splitters literally out of the list of possibly usable devices, which then increases costs for cooling again, because you then have to install a proper splitter device with an exterior unit instead of cheap window splitters (love the devices btw. but they really only can work with the US window design)

@@DoomWarriorX Not all American houses skip insulation. David's in Texas, where it rarely gets cold enough to need heating in the winter, so most houses there skipped insulation in the past. Now that climate change is giving them scalding hot summers every year, that's changing. New houses focus on sealing and insulating so that they're easier to cool in the summer. My house is in Tennessee and it's got insulation in all the outer walls, the attic and along the bottom floor joists.

its insulation bruh not "Isolation" And no it isn't the American way it's the moronic way. Smart Americans indeed use the correct insulation in their houses. Stop spreading Bs stereotypes around that oh all Americans stupidly just run their AC systems at max 24/7 instead of properly building the houses with insulation. Where did you even come up with such a stupid stereotype from. Your just making stupid sht up i guess. Get out of here with saying Americans do it as a insult to literally every person that is blood American.@@DoomWarriorX

@@ManabiLT I'm looking to build a small passive home on my property. Should be an interesting experiment and seeing if I can also make it a net zero home in WI.

As an European who never had air conditioning, INSULATE your houses!!! Massive difference. You can open windows at night to cool the house and close them during the day. And also if you want cool temperatures, one of these window units would be enough to cool your house. Insulation works out in the long run. Do it!

Great to see more content from you, this is exactly what KZread was made for, great stuff.🙂

Now this is right up my alley! I love these solar videos

I love your solar videos! So helpful. I'm also in the South and been thinking about my own system for so long, but haven't found a great entry point. You're getting me thinking more.

a new epsiode of the 8 bit guy is i think one of my biggest highlights of the month

LOVE YOUR VIDEOS. KEEP UP THE GREAT WORK MY FIREND. GOD BLESS.

Pragmatic, honest, useful, entertaining, and real world information. Thanks.

One tip i would give for in a real emergency, is to just all stay in only one relatively small room together and cool just that one and have the fridge and food there as well, so you don't have to waste resources to cooling (or warming) a whole house. (Mind fire hazards if places get too hot of course).

This is what we do (In FL). We may not even use an A/C. I was able to power our fridge, some lights, and some fans last year for 2 weeks on a 1/4 tank of gas (about 7.5gallons) using my F150 powerboost (hybrid). I'm sure we could have made it the same 2 weeks with a window unit in one of the rooms if we wanted to, but the truth is, even at 109F, if you open your house and run fans, you would likely still survive, albeit you would be really uncomfortable. (I also had another 50 gallons of gas in cans, our other car topped of, and the truck had 30 gallons to start... all in all I think we had about 100 gallons of gas which would have lasted us 2-3 months even with an A/C on in one room).

One thought? The fridge heats up the surrounding air so maybe dont keep it in the same room

this is probably the wildest PV setup I have seen and I love it!

Hi 8bit guy. Wonderful setup you got there. I'm just wondering if you have considered the risk of fire (perhaps due to thermal runaway or other failure) or have mitigations for it?

If you do ever think you're going to be without main-grid power for a long time in that kind of heat, I'd really recommend keeping everything as low-consumption as possible. 72 in 103+ heat is a super luxury - if it's 78/80, consider yourself lucky and just chill out - it'll last much longer and keep you from dangerous levels.

with 72 I'd put on a cardigan. do people really enjoy it this cold? especially if it's hot outside?

That’s pretty much his point. 78F isn’t optimal, but in an emergency it’s livable.

Another major difference with window-mounted air conditions and the portable little ones, is that the majority of the heavy-generating electronics, motors, etc are outside of the house. When your unit sits inside, it has to perform double-duty of cooling the room as well as the unit itself according to ambient temperature.

Loved it! Love Ecoflow! Best part was cooking on the driveway. Very exciting experiment.

Definitely have a look at split units as they are the most efficient ones available at the moment. Cheap Asian unit can be found around 400€ here, the first propane (r290) ones begin to come to the market for around 1500€.
