2024 Axopar 45 XC with Air Conditioning by Mabru Power Systems. Making boating COOL again!
The customer on this vessel opted for a generator to be installed on the vessel but also wanted to be able to run the air conditioner while the engines are running but with the generator turned off which we were able to accomplish.
This system can also be installed with an upgraded battery bank to run fully off of batteries without the need for a generator installation with a runtime of about 6-7 hours with both units running at full speed. The units are our SC17VI, variable capacity systems.

Model AC10KLH230,60 provision air conditioning and how can you do
How do you calculate your reported BTU/h based on temperature difference and blower output? Precisely what equation do you use?
I love that intro! You got me dancing out of nowhere.
First of all I would love to see a real breakthrough on marine ac and I applaud your efforts. However, Isn't this much like the old 4-5k cruiseaires that fit into boat hatches? I still have 2 of those units that I no longer use. At least in terms of warm and cold air passing very close to each other as they exit and enter the boat? And that amp draw still seems high if best draw is 20amps. I dont know. I doubt I would prefer this to my current DIY setup of a Honda 2200i generator powering a 12k Webasto ac. All night long even in August this system keeps my Catalina 36 nice and cool in Charleston SC with the generator running in eco mode. Very quiet and vert economical.
Most advocate only discharging Lithium batteries to 20 percent. Two 125 amp hour batteries give you 250 amp hours, 80 percent is 200 amp hours. 29 amp consumption would yield only 6.9 hours. Correct? I believe you have over estimated your cooling system.
That's a far point but also keep in mind that as the unit cools the space down, it will also draw less power and in turn, run for longer. We have yet to have a customer complaint regarding our advertised runtimes but do appreciate you bringing this to our attention.
Excellent video. Thank you
We are copying your install on a one year newer T-11. Same physical layout. I have two questions. With vents in the second stateroom and in the Head, should there also be either a return air path or at least a path for air to escape those two rooms and into the main room when the doors are closed? Second question is this. For the main room, both the vent and return are at the aft wall. It seems the vent would be better located as far forward as possible to encourage more air circulation within the room. Did you look at running the duct behind or below the electric panel to get it further into the cabin? Thanks in advance for the courtesy of your reply.
On new installations, we did away with the head vent as it was a complicated run and it was affecting the cooling capacity of the system as there was about a 20% loss that was caused by the addition of that vent. we did not find the need to cut a return between the aft sleeper and the fwd cabin as the air can pass though the door, even when closed. We looked at other duct configurations but settles with the vent up high that blows forward and have had the best results with that configuration. The link below is to a more recent installation. czcams.com/video/7_zoQctTRiQ/video.html
@@MabruPowerSystemsINC Thank you. My installer and I had already concluded the Head vent was not worthwhile. Eliminating that and moving the aft stateroom vent to the other end of the bed sure tidied up the ductwork.
Thanks for the info! Looking to add AC to a 44’ yacht… and we are VERY interested in setting up a system which will run at night on batteries. Appreciate the ‘real world’ test!
$ for $, these still don’t compare to 110v + inverter…
a 110v unit, running though an inverter will draw about twice the power as our DC units. Sure, you can double up the bank but will also need twice the incoming charge to maintain the system running which can work in some applications with plenty of available power but is a problem on most installations.
What brand Ducting are those?
Could this be installed at Axopar28?
it cannot due to the size of the sunroof
Very poor video Jumping around Glare on screen Sound bad Impossible to follow. I tried Please do better
thank you for the feedback
All have a right to their opinion… but I found the video informative and helpful.* Thanks for the effort man! *not saying I understood the intricacies of the numbers… but learning! ⛵️
Are those grey PVC elbow fittings on the pump and strainers ?
Yes, they are schedule 80 pvc
1000 watts
what is 1000W? The inverter is outputting 120v so the 115v unit is drawing 1200W without a pump and the DC unit is consuming less than 1/2 of that
Always clean and professional install !
thank you!
😎
Mabru is simply the best Marine Power & AC company in Florida, in our family experience for the last 3 years, we used the 12 volts Air conditioning system on our boat for close to 2,000 hs, that would have required 20+ services on the generator which translates to close to USD 15K in services of the genset. Mabru pays off itself. Being able to run the Air Conditioner, have the boat power up all AC outlets, Microwave, electric grill under a headache free system its the ideal (almost a MUST) for a weekender boat! in south florida! Thank you Mabru (and, by the way, Mabru customer service is the best in the world!!!)
Thank you Agustin! It's always great to hear the real-world feedback
Have you considered doing a chiller unit so a hydronic system can be used instead of a single blower?
The issue with chillers is that they are not very efficient in small scale. There are two pumps, that need to run whenever the system is on and the system needs to be able to handle the full load even if you only need to cool 1/10th of the area of the vessel. Variable capacity chillers exist but in line voltage. There is not a DC compressor available that is large enough to be feasible
THANKS NICK! Really persuasive. HOW ABOUT THE VARIABLE SPEED!? Would REALLY sell this if we could see the lower amperage when the speed is throttled down. REALLY an important sales feature. Will check back if you could even just note it here in the comments. All the best! Danny
Danny, both our DC units and our new VI units are variable speed. Our DC units adjust speed based on the difference between set temp and room temp. The 115/230 VI units also adjust speed this way when in auto fan but we took it one step further and have different eco modes that limit compressor speed based on fan speed setting. The 7DC will draw about 18-20A at 12v when just maintaining temp (lowest compressor speed and low fan speed.) I hope that this answers your question
What is the cost to add a system like this?
70.000 btu: frigomar 5 amps.. then 3 to 2
The spec sheet online shows 17A @ 230v www.frigomar.com/en/products/single-phase-chiller-unit-inverter-bldc/ unless you mean running it in eco mode which would not produce 70,000BTU. In addition, you are not counting the raw water pump and the circulation pump that need to be running which draw at least 3A each and the air handler(s) that are distributing the air.
i ask For about Psi? And amper i hope you recive My comment
Psi ? And Amper?
I would love tto have that unit in my small office
Didnt understand one word through that idiotic noise
Possibly research hearing aids instead of air conditioner?
so HARD to hear what you are saying - surely you can do better then this ?
Which exact batteries were used in this test
Mabru 1st gen LiFePO4 100ah vs Optima Bluetop 66ah AGM
Will this unit be able to run on a lithium iron phosphate battery? Or do you need a generator?
@@MabruPowerSystemsINCdrawing 30 amps or won’t run long unless you have a battery bank that cost more then your dinghy
@@jamiehackney4420 a 12v 460AH ah Battery is available from Epoch batteries at this time with a retail cost of $1,699.00. That battery would run this unit for a little over 8 hours, running at full capacity.
@@MabruPowerSystemsINC However that said battery would require 11.5 hours to charge back up @ 40amps. Solar would take days. So you mind as well save money and get a unit to run off a smaller generator. Just my thought.
@@jamiehackney4420 This unit does not work for all customers but it can fit a wide rage of customer needs. I don't use my personal boat every day and have 120A of charge from my inverter so I can recharge my batteries much faster. Even waiting 11.5 hours would work for my application and many of our customers. To be fair though, you are accounting for 100% use of the battery where the calculations I had done were based on 85% discharge and we would use at least a 60A charger, not 40A so it would be just over 6.5hrs to recharge. Other customers use this unit when their engines are running so they have a very small (100ah) battery bank that acts as a buffer between the alternators and the engines. Most alternators today are at least 75A and most boats looking at these have at least (2) so the alternators have no issue keeping up with the unit draw. It's fair that some customers would prefer to have a generator to run everything and that's fair as well. There are plenty of products available in the market to fit those needs. We prefer the simplicity and reliability of the battery powered systems rather than dealing with the noise, maintenance, and dependability issues of modern generators.
@@MabruPowerSystemsINC I am editing my original remarks because after checking, lithium prices are continuing to fall so the dollar cost of batteries is dropping. Maybe 460ah is enough but I am skeptical. And 12k is not much on a boat in warm/hot summer water. Would love to see 8 hours testing in outdoor temperatures where the water like we have here in Charleston hits August 95 degrees. The WATER! Still like I said I applaud your efforts. 12v compressors are probably the way to go. And combined with lithium or some even better battery technology may get us there one day.

Matt, we certainly understand your frustration with price but this is a very expensive unit to produce and not intended for the market of a $6,000 boat. Please let us know if you have any questions.
is this available?
Does Mabru offer a self-priming pump, or recommend one? I have limited space, so while installation is ok, I still have air lock sometimes. Bleeder value is an option, but still a manual solution each time.
Keith we do not have a self priming option and do not have any recommendations at this time. Is the pump in question running off of 115/230v or 12v?
@@MabruPowerSystemsINC 12v
@@keithredmore9473 I've heard of customers using salt water wash down pumps but they are not rated for continuous use as far as I know and they consume up to 4x the energy of the pumps that we include with our units
@@MabruPowerSystemsINC thanks, I have being looking around for pump alternatives, had not look at the wash down pumps. That might work, as our AC is only used for short periods of time. Appreciate the help.

That’s a clean system
Thank you. We strive to keep our installations as clean and user friendly as possible.
Hi Nick, really enjoyed the video. Is the 110v VFD version? What is the efficiency difference between the VFD vs non VFD?
Thanks Bill! Yes, this is the 17vfd and at full speed we consume about 20% less. The other difference is reduced temp fluctuations and no peak starting amps. We can run this unit with no issues at all off of a 2000w inverter. I had a hard time starting a 12k standard unit without a pump connected to a 2800w inverter for reference. This does not take into account the amperage difference when the unit is just maintaining a set temperature. I’ve seen as low as 300w draw on this one
Nice video, thanks!
Do you have a 48V unit in the works?
We do not have anything 48v in the works. We do have a new line of AC powered inverter type self contained units that we believe will be a better fit for the higher voltage applications.

Excellent discussion and demo. These Victron battery monitors are wonderful if one is routinely going off the grid, perhaps using solar, using engines for only a portion of the day, etc. As for the 12,000 BTU system, simply amazing performance. Thank you for posting these.
Very informative. Is it possible to install a 12v version 5,000 BTU in a campervan? Where does the heat from the condenser get blown out.
Not sure I understand: You state below this is a '120v system' but it still requires a substantial 12V system to work away from the dock. Why was this approach taken vs. the 12V 12,000 BTU system (with larger battery bank) you installed on the other Axopar 28? Why not avoid the inverter? Or is the 7,500 BTU unit only available in 120V?
This boat was one of the last vessels that we did with our 120v units running off of inverters and powered by AGM batteries. We didn't have the technology available at the time that this installation was done.
