AC in Camper Van RV on Battery Bank Solar Inverter

Can you run an Air Conditioner in an RV Camper Van off battery bank, solar and inverter? Lets see.

[@Darkmatter321]

Great Video. Iwish you lots of fun and safe traveling. Greetings from Iran

[@fdmackey3666]

OK...Never mind....Watching and listing more carefully......Gave me the explanation(s) I needed. Failure to compute was on my end not yours. Take care and I look forward to future videos from you.

[@TheRamblinCamperVan]

Haha Im glad it helped! Thanks for watching!

[@fdmackey3666]

At last! An explanation on what makes a solar setup on a camper worth purchasing and installing. And a clear demonstration of HOW it works (I think that's what I mean....Forgive me....I'm old.). I'm going to watch this video again but one thing I did not pick up on was how long you could run your AC on solar alone. I'm curious because A) I realize there is only so much room in any RV of any kind for battery bank and B) this is a kind of duh huh question...But WHY does a single use of a relatively small microwave use more juice than the AC that runs for relatively long periods of time? Did I mention I'm not an electrician or anything similar? Excellent video as usual. Keep 'em coming!

[@TheRamblinCamperVan]

Thanks FD! I cannot run AC or Micro on solar alone. My battery bank and inverter run them and the solar just helps replenish the power. The ac on low I can run for 5-6 hours before getting to 50% on bank and AC on high about 4.5 hours with my 4x 6v battery bank of 440 amp hours. Thanks for watching bud!

[@TheRamblinCamperVan]

Also those ac run times are a minimum run time because of the ac being thermostatically controlled and compressor will turn on and off all day ... plus any solar amperage intake so I would say it should run double those numbers.

[@fdmackey3666]

Thanks so much for the kind and easy to understand responses/explanations. The Lovely Bride and I are taking our time looking for the "just right for us and our needs RV" after an initial spate of being willing to "settle". And we almost did!!! After watching your videos as well as those of a relatively small handful of other providers (a rather large number of providers were "culled" due to their failure to explain or just show us, the viewers, what they were doing or had done at sometime in the past to improve their RVs. Some of them also seemed to think they were in the running for the Emmys or something and spent way too much time trying to entertain me. I'm sure you know who some of those providers are.) who take an extra minute or two to tell us WHY you did/are making an improvement/change to your RV AND how it is being done/was done. I was once subscribed to twelve YT RV life/living video providers I'm now down to five, and I consider them, yourself included, the cream of the crop. Keep up the great videos and again thanks for responding to my somewhat dumb questions.

[@TheRamblinCamperVan]

FD Mackey​ Thank you SO much for the kind words! I am glad you stuck around with me! I will continue trying to provide what I consider to be helpful videos and hope they are able to help you with any changes you guys make to the RV you choose. GOOD LUCK in your search! THANKS

[@mullrr]

Thanks for your videos. You do an excellent job and enjoy the information.

[@TheRamblinCamperVan]

Thanks Rob for the kind words!

[@blindspotspotter.2352]

So, I get that one could run an AC on a battery. The real question of interest is can you do so repeatedly, reliably and continuously in hot weather w/o damaging your batteries. I've seen 12 volt AC systems that utilize a highly efficient compressor to achieve such results but I think it requires in excess of 500 amp hours of power and a second dedicated alternator to ensure running time and recharge as the batteries will still be near depletion after running overnight or extended periods.

[@mwdeters]

Hi RC, Another thoughtful explanation...I just expect it now. Thanks for taking the time to educate us. Stay safe Bro, Mark

[@TheRamblinCamperVan]

Thanks Mark!

[@epicvape6546]

Great video. I'm figuring out my solar set up so this info will come in handy. I'm leaning towards 6 battery bank and about 4-5 250 watt solar panels. I'm looking forward to seeing future vids:)

[@TheRamblinCamperVan]

Sounds like a good set up! You have lots of roof space I take it haha. Thanks

[@christophercruise4039]

+The Ramblin CamperVan I'm Sure it Ain't No Class B, LoL!

[@TheRamblinCamperVan]

+Christopher Cruise Lots O roof space for that many panels.

[@CaptainKnots]

Have you tried installing a SoftStart on the AC? It let's you run an AC with a 2000 generator so it should help when used with the inverter / solar.

[@tjtg]

You need ALOT more solar. also a "car audio" 12V capacitor is a relatively cheap addition to stop start up surge hurting your batteries . I am no expert and I Thank you for sharing the vid. Hope you are well and greeting from Australia

[@gsoglo]

Hey RCV.. Thanks for taking the time to do this and other "breakdown" vids.. Very helpful indeed! I have an old 11k btu rooftop unit similar to yours, and bcz of the inefficiency and crazy weight, I'm thinking of replacing it with a fantatic fan or a maxxair on the roof and a floor mount ac. I'd love to get your feedback on that idea..Any others too. Thanks again..

[@WizzRacing]

That AC unit is old. As most newer units in the 10-12k BTU range will pull half that on high. I seen some that run on 11 amps on high with built-in two stage compressor and humidity setting with remote. Maybe cost around $350.00-500.00 depending on manufacture. The one I have now is 6200 BTU will cool 280 sq. down to 44 degrees. All it uses is 5 amps on high setting. The dehumidifier setting produces 5 gallons or more of distilled water in one day as well. Which can be used in the gray tank. So its a win win when boon docking.

[@WizzRacing]

Michael D Distilled water has many uses and since its a byproduct of any AC condenser why not use it? To be honest you can drink it as it's just condensed air.

[@WizzRacing]

Michael D Just send a sample to any university to get the real data. That should remove any doubt. In any case you can run it through a water purifier system on the sink. So the cost to invest in one is pretty cheap given most places people refill there tanks is just from a water hose and source the city provides. But you can wash, clean, refill tanks and radiators, cook, flush and shower with it for sure.

[@TheRamblinCamperVan]

Yeah I will upgrade this old ac one day... I know its a huge power hog. Sounds like you got a great setup bud! Thanks

[@WizzRacing]

The Ramblin CamperVan It's just an old 1998 E-150 hightop that got some very special upgrades where it all works together. As it was purpose built with very special needs for me. It's also how I make my living designing and installing these types systems. As each persons needs are different. When the Used Ford Transit i5 diesel start showing up. I'm going to convert to total stand alone self supporting RV including using Bio Fuel that I can make myself. It should be interesting to learn just how far I can go with it.

[@NCHeel]

+Claude “Reviews4U” Rains Those amp draws are at 110v though, correct? He is measuring at 12v so his number is by a factor of almost 10.

[@shilosheena]

Those are pretty good numbers I did same test with a canteen system older fifth wheel I was pulling 110 amps outta the batteries guess larger older air unit

[@joshuafalken5912]

use a wind generator with solar is answer

[@jglassman1122]

Very cool I've always wondered what it would take to run the Ac

[@TheRamblinCamperVan]

Thanks for watching!

[@ThreeDogsCamping]

we've been running our 6k BTU window unit off our 1260 solarsystem for about a month now. Running all day in the sun isn't a big issue, we've been able to get as of the last week a near 20 degree difference inside the fifth wheel, and out side. the big issue is our batteries. combined we sit on approximately 645 AH of capacity, or around 320'ish usable capacity at 50% DOD Our batteries are likely similar to yours, where as they have a c20 rating. They are rated at the AH capacity at 20 AH an hour. Long term use of this setup straight off batteries like yours will kill the batteries. but it's nice to stay cool during the daytime haha

[@GuapoVino]

I just read on the Sportsmobile site that they say you can run the roof A/C unit while driving down the road as long as your alternator is a capacity suffecient to keep the batteries charged.

[@Nic7320]

A 136 amp alternator generates something like 1836 watts at 13.5 volts, so there is plenty of power there to run a 700 watt A/C. Of course, you can also run your dash A/C and accomplish the same thing.

[@HeatherSpoonheim]

Well, the fan sounds 'doable' but the AC really seems out of the question on solar. With a large enough battery bank you could maybe pick one day in 3 to run it for a few hours but it certainly would not be a daily routine. I've thought about some sort of swamp cooler rigged up under a vehicle - some pipes wrapped in spongy material with water slowly dripping on them and a very low capacity pump moving the coolant through a radiator in the van and a small usb type fan blowing across that radiator. Sounds rather Frankensteinish but might offer some escape from the heat at maybe 3 or 4 amps power rather than 30 or 40 amps.

[@TheKiloG69]

Running your A/C is doable if U size your solar accordingly I have run mine for several hrs. a day in full sunlight in my solar powered camper using about 600 watts with the fridge as I have been traveling across the US. My system has 500 watts of solar at 62V into a flex max 80 powering my camper with a Go power 1500 pure sine wave inverter with 390 amp hr. 12V battery bank consisting of 2 Crown 6V 390 amp hr. battery's in series. Plus a 2.7 energy eff. Compressor fridge. Also have a predator 2500 watt inverter gen set for hot nights. Check it out on my channel . I like what your doing.

[@TheRamblinCamperVan]

NICE set up bud! Sounds good thanks!

[@jackrodgersjr]

TheKilog69 Have you used a Killawatt to check the various devices in your unit? It can reveal the vampire current users that drain the battery but people aren’t aware of this. Turn off your TV but it still drains the battery, etc.

[@allanreager3306]

Is that 2500 loud enough to attract cops at a Walmart lol?

[@CampervanKevin]

Ok if battery bank is 440 amp hours then you have 60 percent use of that before battery damage occurs. My math says 264 usable amp hours. If you are pulling 50 amps on high ac then that gives you about 5 hours and 15 minutes. That does not account for the 9amps coming in.... which would give you about another 1 hour of run time. Is that right..?

[@CampervanKevin]

+Campervan Kevin 6 hours and 15 minutes approx run time on your battery bank would take alot of heat off you in the worst part of the day. However you would have to cut it off in time to recharge enough to have battery thru the night. Also you would need a tremendous amount of time to recharge the 264 usable amp hours. So that would not be enough to run it next day. I may be missing something as I am still learning here.

[@TheRamblinCamperVan]

Yeah you got it Kevin. The only other thing to consider is that the AC is thermostatically controlled so once the van reaches my set temp then compressor kicks off... and on and of and so on for the amount of time that I run it. So you can assume that the 5-6 hour run time would greatly increase.... almost double in fact.. my AC compressor is off almost as often as it is on. Also I dont need to run my AC on high ... cause in this little van the low setting freezes me out everytime. So thats another thing to look at as far as power consumption. And you already said it about solar intake... I get 13 amps in full sun... and I have a video coming up about adding more solar when you have no room left on the roof .. so I will have another 6.5 amps coming in. Thanks for watching Kevin!

[@CampervanKevin]

you are correct, I did not take into account that you could run on low AND a thermostat was involved. 13 amps is really much more than the 9. Currently I charge my 3 agm's with the alternator, or plug in the van and let the vans system charge it. I run 3 powersafe sbs that store 96ah each. However my a/c does not do a good job cooling my van. It is around a 8kbtu, so I will be upgrading to a 13.5 I have considered solar on the tan campervan, but have not got around to it. I do have a solar suitcase that does the trick. I have only experimented with it a few times. BoB however has 2 100 watt panels and 2 battery banks. I'm a little slow to catch onto this solar stuff but I am learning. One thing I have learned is that I really don't use all that much power. I cook and heat with propane. All my lights are LED. My LED tv uses almost NO power. I can run my cpap over 5 nights without recharge on just one of my 96 ah powersafes...soooo

[@CampervanKevin]

I realize that the holy grail of solar is to run a/c, but with the weight and cost I don't think I will do it. However I will watch and learn from everybody I can.

[@TheRamblinCamperVan]

You got the right idea for sure Kevin! If you dont use much power then there is no use in getting crazy amounts of battery bank and solar. If you have 2 100w panels on BOB and getting 9 amps max then I am guessing you are not using an mppt controller? I was getting 9 to 11 amps max from my 2 100w panels when I was using a pwm controller... since I switched to mppt I get UP TO 14 amps max when full sun out and batteries actually need the charge. Hopefully that helps you with a few extra amps if you want them. A renogy mppt 20 amp tracer controller is quite cheap and will do a bit better than a pwm controller. Thanks Kevin hope all else is well bud! Take care!

[@mudspringer]

I'm curious about what AC you have. I also have a Samlex 2000 Watt pure sine wave inverter. So far I tried it with a 5.5 Amp window unit but the Samlex just isn't strong enough to run it - it just cycles on and off.

[@iketheranter9126]

The trick is to park in the shade and have your panels in direct sun nearby

[@GrantSR]

Do(did) you connect the charge controller and the inverter to the batteries via separate wires, such that your ammeter is(was) measuring the current coming from the battery terminal, which may include current supplied from the panels in addition to current supplied from the batteries?

[@Billodnh]

Impressive

[@danielchais4603]

Regarding the new light bulbs and newer cars getting greater miles per gallon.... Can advanced AC compressors someday have such great 500 times advancements where a simple battery will work

[@TheGbortnick]

I have a 96 pleasureway dodge van like yours . I have 2 house batteries and 1 motor battery . when I watch TV am I drawing from 3 batteries or just the 2 in the back. Is there something I can do so I can still start the engine in the morning after a big tv night ?

[@TheRamblinCamperVan]

+George Bortnick Your starter battery should be a separate system then the 2 house batteries in the back. So you should be fine starting up after using the tv which is on 2 house batteries in back. Thanks for watching!

[@GrantSR]

I have a few questions, which I'll post separately: Your solar panel power meter, the one mounted on the wall: Is(was) it showing a calculated, theoretical maximum output of the panels if there was a zero ohm load (shorted), given the amount of light falling on them now(then)? Or is it showing the actual current coming out of the panels before the charge controller? OR is it showing the actual current going from the charge controller to the batteries?

[@jimbarnaby3547]

Good job. We went a different route by using 750w on our trailer to directly power a 5000 BTU window unit from around 10 am to after 3 pm. We can run it before and after peak times with small losses to the 675 Ah bank too. Then it is a balancing act between the cycling of the compressor and recharging the bank when it is off. We pull 40-50 Amps in good light and the little A/C pulls mid 30's with the compressor on, much less when it is off. One thing is your amps out will go up as the pressure of the compressor comes up.

[@arthurgrant8372]

assume this would be doable with the engine alternator providing additional charging amps?

[@robbywilson6729]

I guess I am a pussy, but I can't hack 90 plus without AC, especially if I am in a place with retarded humidity (ie: Georgia in August). The van turns into a sauna really quick. In conditions like that I tend to either hangout someplace with hook ups, or the else the generator is coming out really quick. I have never fully understood the aversion to generators by some folks in this gig, especially since the use of gasoline is hardly frowned upon in other situations. I can get almost 10 hours of power on a single gallon of gas normally too, even when exercising almost zero regard for conservation.

[@TheRamblinCamperVan]

+Rob Wilson Yeah 90 and humid is horrible haha. I would probably get out the geny in that situation too.

[@robbywilson6729]

Don't get me wrong, this state is beautiful, just silly humid in summer, even in the dead of night. It is still is not enough to keep me from my fav hunting and fishing spots in my baby though :)

[@TheRamblinCamperVan]

True! Its all about locating weather you enjoy year round. But in those out of our control locations we need/have to be in at the time for any reason... its nice to have a backup plan.

[@robbywilson6729]

what I use mine primarily for hunting with my group of friends. Hunting is a crack of dawn endeavor most of the time, so we are out of the heat of the day for the most part. If we are in a part of the state I know well, I have a few pet RV parks that cater to outdoor sportsman that I always go to. It's a blast. However, there are a few places on private land we go to with permission and there is absolutely nothing around for miles and miles. Staying out of the Georgia heat for a few hours until the sun goes down and we can start a fire is my SOP, thus the generator. I am not the nomadic type, nor am I looking to make some kind of political statement with my RV, I just like the outdoors. To those that want to? More power to them. It takes all types to make the world spin.

[@realredrebel]

It would have been nice to see what your charge controller was doing.

[@TheRamblinCamperVan]

It was bringing in about 9 amps during this video shoot... I was not getting a lot of solar but I also only get a max of 13 amps with sun directly above van and clear skies... only 2x 100w panels right now but I will be adding more. Thanks for watching

[@traviscompton8049]

this is exactly the setup im about to do. i want to be able to run all the systems off the battery bank and solar. any tips other than big bank and lots of solar?

[@traviscompton8049]

i was going to get just a 110ah bank but after seeing this i think ill have to bump it up to 220 at the least.

[@greatquotestoliveby]

the amperage will continue to rise as the voltage drops in the battery untilled the voltage drops to or below the low cut off of the inverter.

[@mudspringer]

Also - one other question. I get that the batteries won't run it for long - but what about when the engine is running? Can you run the unit when driving? Thanks in advance...

[@rickdees251]

Won't help much. People are totally clueless about how much power AC's use. I find laughable with those who claim it's possible to run AC off batteries and a inverter. They are totally ignorant, explain to me how long is "a good ittle while"? In this video he's giving amps being drawn which mean NOTHING because amps are NOT a measuremen of "power" being used. But what's the difference, if people think turning on the AC for 5 minutes proves "it's dooable" they are delusional.

[@mudspringer]

Amps means NOTHING? Not true. Power is measured in Watts. Amps * Volts = Watts. If you know the Amps and Volts you know the Watts - so you know the power being used.

[@rickdees251]

mudspringer I'm happy to discuss my point with you if your interested. Your apparently missing my point. Amps mean nothing when trying to determine how much power a load is pulling. It is the power (watts) the load is pulling that will determine how long the batteries will last amoung other variables. Watts were not given and the voltage was not measured under load so the calculation CANNOT be done. When it was drawing 48 amps and 38 amps, as the compressor was running with high and low fan respectively, how much power was it using? Give a number with as much accuracy as he was reporting the amps being drawn, not some guessing estamate that could be off by as much as 25% if we don't know the voltage? Simple question, what was the watts being used? I'm saying "I don't know" and you can't say and be accurate within + or - 25% because you have to guess at the voltage. + or- 25% is a big difference because it will affect how long the batteries last by more than 25%. This is not an argument, this is a discussion of the facts of what's going on during the test in this video. We can have different opinions but we can't have different facts. Facts don't have opinions and they don't change because of them. Cheers!

[@frankdumlao32]

How would it work if you were driving down the road with you vehicle alternator charging the batteries? Would this work?

[@TheRamblinCamperVan]

That would be doable and makes sense in a larger RV for cooling... but in this little campervan the front dash ac cools the entire van just fine. Thanks for watching?

[@Adambx]

First I'd like to say thank you very much for your VIDEOS they are very helpful I am thinking of getting a Roadtrek with a under the hood generator , 3000 watt inverter and 200 Amp lithium battery no solar panels A/C on it is 11,000 BTU how long do you think I can run A/C

[@brucebear1]

It's all about the watts. As an example, Dometic (a good, ordinary air conditioner supplier for RVs) offers a baseline model that requires about 15 amps at 120V. That's 1800 amps. Some inverters rated at 3000 watts will start (the start current is often higher on an air conditioner than the steady-running current) an 1800 watt air conditioner but you're not likely to find one that will unless it's a pure sine wave inverter. How much power does the Roadtrek under the hood generator deliver? If it's putting out full charge voltage of approx. 13.4V, you would need a theoretical 134 amps. This is possible but that's a high amperage for an under the hood system and a generator that's run at it's full rated amperage won't last long. You'd probably need a system that specifies a maximum output of about 170 amps (at 13.4V) to have reserve. All this above is pretty simple numbers. What gets tricky is the issue of cycle time with an air conditioner. Air conditioners start and run until their thermostat switches them off, then after a while, the thermostat will switch the unit off. Since you have a good battery, you can expect a "cycle" effect. If you're putting a fair amount of power into your battery with the generator, you'd find that the battery may run down a bit as the air conditioner is running, then when it cycles off, the battery gets charged up again. The real question is whether your battery is fully charged or run down after 8 hours and that will depend on amount of power from the generator and the cycle time of your air conditioner. Oh, it should go without saying that if you're in a really hot place, the air con unit will run longer on each cycle and the "off" time will be shorter. Also, don't forget that every item in the system will lose some power to inefficiency. If you put 1000 watts of battery power (12V) into an inverter, you won't get 1000 watts of 120V power out of it. This can be a problem in some instances. It's all a matter of getting the balance right, with the correct amount of reserves.

[@Nic7320]

You meant 1800 watts, not amps.

[@bobwilliams8317]

if i were you id duct the inverter to exhaust outside so the heat isnt exhausted into the cab. just a thought

[@NCHeel]

You said 440ah at 12v. Are the 6v batteries 220ah each?

[@TheRamblinCamperVan]

Yes... 4x 6v batteries wired in series and parallel. Each battery is 220 amp hours.... So after wiring 2 together to make 12v the amp hour remain the same. After hooking up each set of 2 batteries together then add together amp hours to get 440. Thanks for watching

[@Camp_Runamuck]

Why didn't you use AGM Batterys ?

[@TheRamblinCamperVan]

+VW Vanagon Westfalia Travels Because they were double the price for a similar battery in AGM.

[@Camp_Runamuck]

+The Ramblin CamperVan ya but much safer .. No Gases .. No Oder .. Health is worth something ..

[@Camp_Runamuck]

+The Ramblin CamperVan I was scared to use gulf cart Batterys in my VW . I'm told the AGMs last much longer as long as you have a switch that kills the system at about 11.0 volts .. I only run a 12 volt fan and it runs all night .. Don't need A/C much with a pop top . I also use a 12 volt engle refrigerator. Run my bi pap machine on 12 volt also .. I find it don't take much if everything is 12 volt in your van

[@TheRamblinCamperVan]

I was able to save money by getting the lead acid batteries cause I have a 100% sealed battery box that is vented to the outside. With this custom box I am able to save tons of money on batteries. A properly maintained lead acid deep cycle can last up to 10 years. These Trojans are known for that.

[@jimmytk5958]

+The Ramblin CamperVan I have the same size batteries in my Rv, 4 of them. How did you vent your b box? My Rv is new so if i cut a hole out id want it to look proper and not leak and also stop bugs an rodents...

[@Brainsmachine1]

4 panels if you can

[@TheRamblinCamperVan]

+Brainsmachine.bc I got 3 up there now after this video was made.

[@Brainsmachine1]

I was wondering how much power the small window units pull on low. Will 3 handle it ?

[@TheRamblinCamperVan]

I have not tested a small window unit but I know it uses WAY less power than this old ac unit. I bet 3 or 4 panels would replenish batteries instantly running such a small unit like a NEW 5000 btu AC.

[@jglassman1122]

How long do you think it would take to drain your battery bank with the Ac on.

[@TheRamblinCamperVan]

Its hard to say because of it being thermostatically controlled... meaning once ac reaches temp set in van the compressor turned of for certain amount of time before kicking back on. So I will give you the least amount of time ac can run on low and high based on pulling max power as if compressor was running the whole time. Draining bank down to 50%.... with ac on low would run for 5.7 hours approx. And ac on high would run for 4.5 hours. These times would be closer to double that time with the compressor turning on and off regulating temps. And not calculating solar charging during this time as well. Thanks for watching

[@TheRamblinCamperVan]

Keep in mind this is an old ac unit. A newer ac unit will use half the power or less. A good idea for me to upgrade if I really want to power it from bank and solar.

[@TheRamblinCamperVan]

Around $600. 2x 100w panels, mppt charge controller, breakers, wiring and hardware.

[@Stellarsirensounds]

Hey there Ramblin Camper van. I just came across your channel looking at how I'm going to set up my future camper van. I was curious about how to keep cool without shore power or a generator and your video informed me of exactly that! Thank you. Also this may come as a coincidence but, I was actually already primarily interested in a used pleasure way. I can't afford one right now, but when I reach my financial goals I will be assuredly be returning your videos as tutorials on how to outfit it, so please don't delete them haha! Also if your interested in switching to something else someday let me know, I'll could be a potential customer. Anyway I have a question about the towing capacity, I haven't seen all of your videos yet so I don't know if you've mentioned it already. P.S. do you have a patreon account? You could be making money off of your videos through www.patreon.com/ I've seen people make a living this way. Anyway, thanks for all you do!

[@ELGee1]

! 460 watts for the AC?? thats not a lot

[@lynperk]

not practically .get a get a generator

[@brucebear1]

Of course, a camper would need a battery bank capable of delivering approx. 235 amps @12,8V. That's 3000 watts, the power that Dometic specifies to run a 13K Btu "Brisk II" RV air conditioner in a stable state with reserve for starting the compressor; lower than this will damage the unit. A big truck battery, 8D type, will give about 245 amp/hours but since you can't run a battery below 50% charge without damage, you'd need two to run that air conditioner for about an hour. Then you'd need 3000 watts of power equivalent to an hour (you'd never be able to get that much recharge in one hour as a practical matter). Two 8D batteries weigh 320 pounds -- 320 pounds of battery will barely run an RV air conditioner for an hour. "Solar power" - at 13A @ 12V; sure that's 160 watta under perfect conditions. A lightening bug farting on your solar controller would make almost as much power, in real practical use. As you said, "not practically". It's just NOT going to happen without a solar array that will give an *average* (that's not the perfect spike that you can reach for a few minutes a day) charge, after inefficiency losses, of over 200 amps charge per hour per day. Just not going to happen.

Hey there Ramblin Camper van. I just came across your channel looking at how I'm going to set up my future camper van. I was curious about how to keep cool without shore power or a generator and your video informed me of exactly that! Thank you. Also this may come as a coincidence but, I was actually already primarily interested in a used pleasure way. I can't afford one right now, but when I reach my financial goals I will be assuredly be returning your videos as tutorials on how to outfit it, so please don't delete them haha! Also if your interested in switching to something else someday let me know, I'll could be a potential customer.
