All 12V systems have one thing going for them: ease of use/install. All low-voltage (12-48) systems have one thing working against them: current, which translates to low(er) efficiency.

[@kingbee3]

First of all, great series so far. I’m a bit behind, this video is 3 months old, but we’re currently planning our next build and KZbin seems to know that. 😬 The whole idea of an AC unit in an “off grid” van is interesting and unfortunately fraught with a whole lot of misleading marketing. The fact is, it takes a ton of power to chill air, regardless of whether the power is 12 volts or 120 volts or a bunch of squirrels spinning the compressor. That’s just how the universe works. It’s definitely true that eliminating the need to run an inverter saves a bit or power- the inverter has its own overhead. But still, the three most common 12v AC units draw from 696 to 864 watts on high. That’s a lot of power. Take the Velit for example: they say max draw 60 amps or 720 watts at 12 volts. That would give it an EER of over 11, which is extremely good, maybe unbelievably good. 😉But let’s take their word for it. That means that, on a scorcher of a day, starting with a 100% SOC battery bank of 540 AH, or 6480 WH, the AC would flatten the bank in 9 hours, with nothing else running. Sure, solar will add some of it back, but you’d need to be harvesting an avearage of 720 watts the whole time it’s running, just to keep up, which means realistically an 800-900 watt array. Tough to fit on a van. But without replacing what you take out, you’re just going downhill. Of course, it really has a lot to do with your style of travel. If you’re driving every day or two, it may be fine. If your idea of “off grid” means running a generator, then no problem. And of course, plug-in camping renders all these considerations moot. I’ll admit, there are time I’ve wished I had AC in our van, and maybe our next van will have it (if Ford ever gets around to building it 😂). But if you’re considering it make sure you do the math and have reasonable expectations. Don’t just assume that just because it’s 12 volts it magically uses no power. Regarding the Mabru unit mentioned: the specs on the website would give their unit an EER of 16. 😮 12 is considered extremely high, what the best residential mini splits achieve. So take their claims with a grain of salt. Keep up the good work guys!

[@evil17]

Agree, my only real caveat to that is I think ur being generous with the amount of solar you can ever expect to harvest from flat mounted roof PV even if he had the realestate for it, I think he will need to upgrade the alternator & run the vehicle AC to help reduce the load on 12v AC while charging the batteries simultaneously, trouble with that is the engine heat adds a lot more load to the AC’s as it is running and blowing hot air all under & around the van, bit of a catch 22 effect.

[@annahpaquentin6047]

We have used the kzbin.infoUgkxOTeIs0vv4_9B5hsmnLsk9r930uDQLu_Y for probably 30 hours with our camper and it’s been great! The noise level is really only noticeable when running the AC and other appliances like the microwave, hair dryer, or coffee pot. It’s not huge like other ones and it has wheels so even at 90lbs, I can move it!

[@jjjacer]

Although Affordable is still a broad term, for me it would be far from it, the van i would want to add it to cost me half as much as the A/C unit and my budget pretty much limits me to whatever i can find second hand (looking for a portable house A/C unit under $200, as my inverter is big enough to run a small one). But i will say that one is one of the cheaper rooftop ones ive seen.

Don’t be too quick to say overkill. I have a pro air 18000 in my 170 and in the sun in 90 degree weather it’s just ok. I really like it for when you go in a store or out for dinner when you leave the van and you come back and it’s not an oven in the van. In the sun your using 100 amp hours per hour so in reality it’s only optimum for nighttime. Look into a 100 amp buckboost so when your down to 100 amps in the morning you can charge as fast as possible or better yet get a second alternator. Solar just won’t cut it for AC. By the way you can find the sos 🆘 fix on KZbin. I haven’t tried it yet but it looks easy

[@longtimber1]

Upgrade to 48V. I squared r losses are just too high. 12V is a nightmare.

[@kimmer6]

Cars and vans don't come with 48 volt alternators.

[@rnordquest]

@@kimmer6 not for cars but you can add a 48v 2nd alternator to vans and trucks.

[@kimmer6]

@@rnordquest Its an expensive waste of time going to 48 volts on a vehicle for the power system. The cable runs are very short on van 12 volt systems so using 4/0 or 2/0 cable to the inverter is not expensive. There are combination charge controllers for 12 volt systems to limit current from the alternator to lifep04 batteries and also act as a MPPT charge controller for solar panels. That way you don't cook your alternator if the battery bank is at low charge. There are a ton of 12 volt DC appliances and fridges that don't need to go through an inverter with its losses. Where do you buy 48 volt appliances? My motorhome has 12 volt lithium batteries 800 amp hours, 10,000 watt hours, 4000 watt psw inverter. My combo MPPT charge controller between the engine alternator is 60 amp and there are 600 watts of panels on the roof. The fridge, furnace, fans, and Chinese diesel heater are all 12 volt DC. No inverter losses. I see 80 to 100% state of charge except when I run the AC a lot. It's overkill and I do not worry about electrical losses. Besides, 12 volt components are everywhere and you can get replacements from eBay and Amazon in 3 days. Not so easy with 48 volt stuff. I am not against 48 vdc but really, in a vehicle? My home bank is 48 volts, 7500 amp hours, 96,000 watt hours with 12kw split phase inverter charger. There's a smaller 24 volt system backup with a pair of 3kw high frequency inverters and a 6kw split phase inverter charger and 3600 amp hours of batteries. It's enough to power my clock radio for a while.

[@rnordquest]

@@kimmer6 I was thinking 48V for AC with 48V worth of panels. Maybe that's not the best solution. 12V stuff would stay the same. The efficiency of 48V is simply better for inverter and alternator. Well according to Balmar anyway.

[@kimmer6]

@@rnordquest For stationary home backup power, a 48 volt system is the way to go. Some all in one inverter charger units with built in charge controllers can take up to 600 volt solar input. But on a vehicle such as a motorhome, 12 volt based components are readily available. cheap, reliable. Nobody really cares about losses and the batteries, inverter, charge controllers are all in close proximity. Price a Balmar alternator. My 24 volt unit on my boat was almost $2000 and needed their external regulator. On a vehicle, there is rarely enough room to add an additional alternator and the work has to be custom fabricated. That's expensive work. Thanks to car audio enthusiasts, there are many direct replacement alternators in 12 volt configuration that output 200 amps and more. I have a motorhome, boat, and house solar/battery bank inverter systems and built them myself from components. I recall buying a replacement Renogy 12 volt 3000 watt inverter in Flagstaff for my motorhome. I got it shipped the next day to a restaurant with the manager's permission and was on my way across country to Vermont with very little delay. Now I carry a spare inverter, charge controller that will take 150 volt solar input from my 800 watts in solar panels, and a 60 amp DC to DC charge controller to limit my alternator charge current to the 600 amp hour lithium battery bank. Now that I have spares, I'll probably never need them.

[@cferdinandi]

Mabru (a marine AC vendor) now makers a 12v rooftop AC for van lifers and RVs. 12k BTU with a 30-55 amp draw. They recommend 500ah of lithium for an approximately 8-10 of run time (assuming no other load on the batteries, which is of course unrealistic). At the lowest draw, 300ah would last up to 10 hours, but realistically you'd want more than to have a safety margin and to account for other things pulling on the battery (fridge, lights, etc.) at night.

[@larrymichelson]

But at least it is easily removable when the time comes for that.

[@jamesjob9067]

It would only be good for a small van or a tiny off grid cabin.

[@johnnyhellfire6]

That's a funny idea on what "affordable" is...

Lose the music....annoying, no one came here for a concert.

[@listenup9322]

You didn't show anything about the wiring. This really could have been a video about neighbors while working.

[@MathersOnTheMap]

There’s 2 wires that are 6 gauge, fuses included wire them to your bus bars 👍🏻

[@davidvalens3337]

how cold can you get your van with this AC?

[@vanvittles8651]

thanks for the info and code! installing mine early this week. Can't wait!

[@envj8813]

Why are you deleting comments? I mentioned a more affordable option for the same ac unit. Must be getting kick backs from velit

[@iraa9935]

Can you repost the other options?

[@dreday4612]

Will that be good to use in a food truck?

[@ivansidoruk7542]

1500$ for an ac? thats not the cheapest brother lolol

[@egn83b]

This is baffling to me, average people dont understand 12v systems and how expensive it is. Just cuz your car or whatever is 12v dont make these systems efficent or cheap. Copper costs alot and battery capacity makes batteries cost alot in money and weight. A 48v or higher system is easier to run then 12v and cheaper. The saving would be less weight and less copper and more fuel savings.

[@reubenj.cogburn8546]

Personally, I would just upsize my battery Bank, just as you have done. Secondly, I would simply make sure that my inverter was spect out to something larger than I think I'm going to need going in. Lastly, I would simply use a $150 window AC unit, that is much easier to service should the need arise. The only Advantage to having low voltage DC current air conditioners is that they do not require alternating current. I have alternating current. I can see where this might fit a niche, but I see no real practical long-term use in terms of money well spent. My little 5K BTU window shaker has been cooling off my trailer for over a year now and it only takes three to four hundred watts of power to run it Done deal, bottom line - great for glamping, waste of money

[@MathersOnTheMap]

I hear ya Reuban about a window unit on a trailer with straight walls. But I don't really see where you could put a window AC unit on a van with curved walls that will maintain a water seal and one that is practical for a livable layout. We use Battle Born Batteries, which are around good chunk of change so to upgrade add even more batteries to our battery bank (which also takes up more space in the electrical area) basically evens out vs spending the money on a 12v roof AC evens out in my opinion.

[@reubenj.cogburn8546]

@@MathersOnTheMap finding a place to mount a small rectangle is not a challenge if you have any kind of mechanical ability. I built my own batteries from lithium iron phosphate sells I ordered directly from China. My little 7 x 14 trailer has three thousand watts of solar collection, and over thirty thousand Watts of battery power. Each 560 amp hour battery I built cost me $1,100. I now have all the power I will ever need, for the rest of my days. What I am saying is you don't have to buy things off the shelf, or have appliances that are plug-and-play, a little elbow grease can be worth thousands of dollars. I have proof.

[@MarkoManiac]

​@Reuben J. Cogburn now ya just gotta learn how lossy dc to ac to dc is and you'll be set. Not a chance I'd run an "ac" apliance on my DC power bank for no reason.

[@reubenj.cogburn8546]

@@MarkoManiac lol, the reason is my air conditioner cost me much less than $200. This air conditioner he's promoting sells for $1,600. Getting a clue yet? I live the good life, and I use electricity. I can buy any appliance I want at any store I want and simply plug it in. dc appliances means you're stuck at the RV store or the internet. So, stay true to your DC love, and I'll stay with the convenience and diversity of my setup.

[@SuperBacDoc]

@@reubenj.cogburn8546 , it definitely works for you and the Physics and chemistry definitely back up your position. Some of us are concerned about the esthetics of window ac and the bouncy ride of van. Every situation is different and I would spend extra for something like this mounted on roof. It all comes down to personal preference and budget. The best thing about videos like this are the options you can get.

[@ChristophPuetz]

What you did not talk about at all is the noise level. The Dometic is hideously loud as an example. All the reviews on KZbin or anywhere else conveniently ignore that. Bought that thing and it is pretty much useless if you plan to sleep while it is running. How is this one? I mean - be honest. The price and that it cools is one thing, using it in real life is what matters in the end. I have a glorified RTX 2000 on my truck camper, but if I want to sleep at night I better not use it.

[@thelongdaysofwheeling124]

So about 10k in batteries and AC unit. Hahahaha.

[@vdynmx]

I dont get it, why not just run the cars AC?

[@poikelos6291]

this doesnt seem cheap since it only does AC not heat.

[@BruceP]

And pray tell how is 1800USD "affordable" when a normal rooftop ac unit is $800? For that price you can just buy a regular AC unit AND the batteries to run it for the same price as your so called affordable unit. Glad you got paid though.

[@dustup2249]

A 20 amp draw for only 8000 BTUs is a very bad trade. A large 100 amp hour LiFePO4 battery with a 80% DoD will give you 4 hours of comfort in an 80F climate. Any money you pretend to save on a $1,600 RV AC unit will end up in at least 4 expensive 100 Ahr Litium Ion batteries. Must be your RV does not have a refrigerator...

[@karlroebling3316]

Love your chart but let's add one more row: Efficiency. As all are 12 volt systems, we need only divide the maximum BTUs by the maximum amp draw to see who delivers the most for the least. Dividing 6824 BTUs by 58 amps we see the Dometic provides 118 BTUs cooling per amp. Similarly, dividing the Nomadic's 11830 BTUs by its 105 maximum amp draw yields an efficiency ratio of 113 BTUs per amp. The Velit easily wins on efficiency, when its claimed 8000 BTUs are divided by its maximum 60 amps draw, the efficiency ratio is 133 BTUs per amp of electricity.

[@cluberic]

$1,600 ac is "affordable"?

[@jeffcohen9246]

Definitely overpriced if that really is it

[@robertcaudill3272]

was yours loud as f*ck when you fired yours up

[@RacineandPeter]

This is amazing! we install our Velit AC unit tomorrow and this was a huge help figuring out the best way to install it!

[@MathersOnTheMap]

happy to help!!!

[@nickporreca587]

How did the unit work during the summer? I am also in NJ and have a 115 volt RV A/C unit on my Skoolie and don't have A/C in the factory vehicle and tried to use it while driving but killed the batteries after a few hours.

[@SOLDOZER]

Those things draw a ton of amps.
