That was a very detailed report-good job.
Very much nice split screen unit.
Very nice and forsure a cheaper route than a APU nice job however if the ac unit can't cool the cab down to at least 65 degrees in a 125 degree day it wouldn't be worth it to me.
Nice!
Can do review video please. I really wanted to see if its still running strong. Thanks
Good video. 7000 to 12000 btu is more than enough for a semi. After I run my mini split for about 7 minutes its cold in my truck. I recently saw a video about solar powered 12 volt mini-split units. I'll be getting one in the future.
What kind of battery you have put or you using the generator for that unit?
@@martes8877 I have a Pedator 4375 and I'm using regular truck batteries.
Hey bud, can i have your contact so I could ask you a few questions about the mini split? Thanks
Hey bud I have a 12 V AC unit on my truck I’m trying to make it run with a 4000 W generator what do I need to get it going
@@ElCochiloco369 12v ac? You mean dc. Um im thinking that whatever system you are looking at should give you power requirements so if using 12v dc it should say like needs fused for say 60 amps so running it would pull say 50-60 amps then you would need minimum of 12v 60a converter but i would go bigger and then hook it all to the trk batteries. However i would look into a regular mini split system that runs direct off generator so no bats or converter required as less space needed and no conversion power loss unless you are planning a large bat bank to run system with no engine required and bats charge off trk bats when driving. Thats my opinion
Great review! Still happy with it? Curious if you could record another one at a lower setting on the compressor?
We also want like this unit.
Curious about the compressor speed control. If I can get one separate
Are you still happy with this install. I plan on doing a similar install
The link provided goes to a different system... not sure is ia the same ?
You need 1000ah deep cycle battery bank. With a stock alternator it will take 8+ hrs of driving to charge them. 1000ah will be enough to cool the sleeper 10-12hrs depends on temperature.
One problem. Weight!!! 80lb per battery means 800lbs extra weight. Not good.
isnt that why theres a generator running? smh
He looks to be doing gen route however yes bat bank is a green route in place of gen. A little heavier yes but quieter and no extra fuel. Drive all day get full charge and full nights ac. Depends on how one wants to go
I was thinking to power this from a deep cycle battery….
Hey went on link.ypu posted nothing there would you happen to have any contact info for seller don't wanna use aliexpress looking a pioneer unit but does look sturdy enough
I have installed a few of these units and wire directly to truck batteries. Then installed honda.generator 2200 and connect a 40 amp battery charger to the generator and wire into the batteries....... Good for few hrs ... any thoughts. Not the best route if u want more hr run time
I built lifepo4 batteries 12v 280ah each from 18650batterystore.com. 2x of them gives me 15-25hrs depending on outside temp.
This video is listed at 2yrs old.
I’m curious of the longevity of the split system.
Thanks!
I sold the truck. But others have installed it and works ok
Very nice video, I have a3500 watt predator inventor generator from harbor freight & I have aluminum box which fits the generator, so my question is,do you think the generator will get too hot with open door?
Cut holes of some sort of holes and run exhaust direct out and put some sort of louvers over holes at one end then other end cut more holes and fit a 12v radiator fan feeding fresh air powered by gens 12v battery charger plug then when ever gen is running you have steady supply of fresh air
But when truck is running and driving it can run off of regular battery correct?
If you set up a three way switch to connect it to truck 12v system it will.
I just finished installing a similar unit in my RV but when I went to charge it with refrigerant I realized they have some kind of weird Chinese style fittings on it. My gauges and adapters don’t fit. Where did you find the fitting adapters to fit this for charging?
Mine took regular 134a connectors.
@@ne7s29 thanks. I just realized the home AC kit uses different connectors than a car AC kit. Got it.
Where is the link.?
our AI MDVR with ADAS and DSM camera is in good perference, would you like to test?😊
Yes. If you send I can install on truck and do review.
How well does it cool the truck in summer time?
It performed very well. If during installation the ac system is not vacuumed properly before releasing r134 freon the. it will not cool as designed because there is moisture mixed in with the freon. Proper installation is the key.
@@ne7s29 ok. I have a 5000btu portable ac in a freightliner classic raised roof and it struggles in summer. Was thinking the split system would be better.
@@merrissaramos7383 Well this air conditioner does not freeze you but it definitely took the moisture out and I was satisfied with it but this is not going to compare to some humongous unit
@@ne7s29 Texas summer's are no joke. And didn't want a big mini split this one looked good but I'll keep looking. Thank you.
How was ac performance in summer?
Very good. Kept truck very comfortable and dry. At 100f It wouldn't hold 60f but it would do 70s
Is this unit still holidng up?
Yes.
You should have done a temp test so we could see what the temp is
Air coming out was freezing cold. Like a good window unit would.
can you put a link for the transformer please
110V to 12V transformer is not rocket science, go eBay and grab one 50W or above as he said
Do you link. Tge one I find on ebay is 1000$
1:40 I do not understand, why is transformer required ?
The air conditioner is 12v and a gasoline generator output 120 V so you need to step down the voltage. The generator does have a 12v output option but it is limited to 10 amps. The air conditioner needs 40 to 60amp at 12 V. I highly suggest going with lipo4 battery Fram amazon. Get 2 200ah batteries and you will be better off. No generator noise or fuel to worry about or oil changes. Get renogy 60amp dc to dc charger for 250$ to properly charge the batteries fro. Your alternator and put them in your cab. Much less weight too.
@@ne7s29 thank you for your reply ! how much batteries I need to have to skip the generator ? for 5 hours quiet a/c-ing
noise from this generators drive me crazy
@@Uc9uE3pKsS6uQ one 280ah lipo4 battery from Amazon goes for around 1300-1700$ you will need a dc to dc converter as mentioned in last msg because this lipo4 battery can charge so fast it will burn out your alternator. The 280ah 12v battery will run for approx 8hrs up to 10. It all depends on the outside temp.
@@ne7s29 5 days ago I purchase this (see on bottom) and waiting to arrive, its similar to yours. When come and mount will share with you my experience.
Thank you one more time for sharing !!!

Is it still working?
Yes
@@ne7s29 awesome!
That thing is load.
Not powerful enough. I installed the same unit in my T680 together with 880ah battery bank and a 320amp alternator. When it's 80f outside at night it eats up battery bank to 12.3v. keeping the sleeper at 19c=67F for 10hours. When it's during the day 100F outside. It won't cool the sleeper any cooler then 74f. It's powerful enough to satisfy 80% of the yearly needs. Two units are needed and 1500ah battery bank +320amp alternator to meet the needs of a t680 sleeper.
Is that with the sleeper curtain closed off from the cab? Or does the T680 not have one?
@@fnfastone that's with the sleeper curtains closed. It's mounted under upper bunk bed. It's enough to keep the lower half of the sleeper cool. It's ok for a Solo driver. But if I circulate the air inside the sleeper it's not powerful enough to keep the whole sleeper cool including upper bunk. 7000btu is not enough.
what type of batteries for the 1500ah? .. this vid. is the cheapest I've seen for lithium which can be discharged to 10% and get 5k cycles. ruclips.net/video/3trqJEDEj6A/видео.html You say that 74f is not enough cooling during a 100f day?
@@tex959 just go to Sam's club and get deep cycle marine battierries they're the cheapest. It will say on the lable how many amp hours they are. Lithium is expensive and requires a BMS and battery heater pads. Lithium wont work on freezing temperatures, they won't charge in cold temperature. As for beginners it's better to go with deep cycle lead acid batteries
@@wojciechzgodowski I appreciate the feedback but I assume when people tell me they prefer lead acid, they have never tried a lithium system. correct me if I'm wrong. I understand cost can be a barrier.
In the case of the deep cycle lead acid, you will dramatically reduces the life of your battery if you routinely drop below 50% depth of discharge. which means you need about 75% more amp hours of lead acid than a lithium which can go 85% depth of discharge without reducing the life of the battery. The guy in the above link paid about $1k for 560 amp hours including bms and wiring. That's 476 usable amp hours. consider the cost of usable amp hours with lead acid. A 100 amp hour battery for maybe $150 at Sam's, will give you 50 amp hours of useable power. That means you would need 9 x 50 lb batteries which ads 450 lbs of weight compared to the 75 lbs of weight for lithium for a cost of $1350 for the "cheaper" lead acid. Now consider that you can get 10+ years of of lithium compared to 4-5 yrs. out of lead acid(assuming you don't regularly drop below 50% depth of discharge..
I live in a warm climate but even if I didn't, the BMS will shut off charging below freezing and if I really needed them in freezing temps, I could easily add a 50 watt. heat source attached to a thermostat. They make similar heating element for pipes in cold weather. If you're just heating the battery box, and it's well insulated, it won't take much power because it will automatically cut the heat on and off to maintain above 32F
Also, consider that you will only get the rated amp hours out of lead acid if you spread the amps over a 20 hour period. If you spread the amps over a 5 hour period, for example, you will lose quite a bit of total amp hours and if gets much worse the faster you drain power. This is called the peukert effect and only slightly affects lithium and dramatically effects other batteries.
Everyone I've ever talked to in the RV world, that has used a lithium system, tells me that they will never return to any other chemistry even if cost is a factor because they save money in the long run.

Where did you buy the thing give me the number
Those international trucks are a peace of shit and the sleepers aren't that big but anyway the system for the a/c unit it's kinda cool
VERY NICE A/C UNIT AND VIDEO! I'M SURE A TIME WILL COME WHEN D.O.T. DOES ANY LEVEL OF INSPECTION, AND WILL PUT A TRUCK OUT OF SERVICE FOR HAVING EITHER A GASOLINE POWERED GENERATOR OR CONTAINERS OF GASOLINE ON THE VEHICLE.
Nope. It’s not illegal to have a gas powered generator or to carry gasoline under a certain amount. And never will be
