12 volt 22K BTU just announced today by recpro.com https://www.recpro.com/recpro-12v-r...214525132&mc_cid=051e1fc4f9&mc_eid=666408a033

That sticker shock is less than I thought it would be! For 20k BTU, im kind of impressed. Too bad its only 12v. Who wants to run 0AWG like 30 feet to their roof? Im guessing this is more for Sprinter Van's etc.Jesus.
That's really shooting for the stars. 100a max draw.
Variable speed is good though. Probably be a nice unit after the sticker shock.
Too bad its only 12v
Well. Yeah. The form factor is a huge plus.That sticker shock is less than I thought it would be! For 20k BTU, im kind of impressed. Too bad its only 12v. Who wants to run 0AWG like 30 feet to their roof? Im guessing this is more for Sprinter Van's etc.
That's awesome, with very nice graphs. I can't find very much information on actual running watts compared to other units!!Lt.Dan
Here is the 48 volt version of the same unit.... https://www.premierproducts.net/order/premier-air/turbo-2-12v-and-48v.html
along with power usage and temp delta... and heat chamber test which I don't quite understand. Recpro is only selling the 12 volt version
Do you mind copying me or sharing the email. My email is rob at rwl. NETI sent them a long email
AWG 2 should be sufficient for 100A To be safe you can use AWG 1. no need for AWG 0That sticker shock is less than I thought it would be! For 20k BTU, im kind of impressed. Too bad its only 12v. Who wants to run 0AWG like 30 feet to their roof? Im guessing this is more for Sprinter Van's etc.
2 ga is still a decent amount of wire, plus the cost of the wire!AWG 2 should be sufficient for 100A To be safe you can use AWG 1. no need for AWG 0
I've seen some people just use 2x 6 gauge parallel for easier handling.
Definitely not the easiest to wire, but I just saw a way - I can run the Wire inside the A/C ducting - at the front and the back of RV the ducts are terminating inside cabinets.
Inside the ducts would be even easier to run a thinner wire - since it's cooled![]()
when you spend $3-5k on a A/C and Batteries to run it - spending $50-100 additional for wires shouldn't be the issue2 ga is still a decent amount of wire, plus the cost of the wire!
If I had to run 2ga all the way to my back ac, from my battery compartment, thats probably a good 50-55 feet, now thats a lot of wire!!
But if the 48v model works out, then I'll only need to run 10ga/8ga, which is much much cheaper and easier!
Man. I keep looking at trying to cram 1800w on top of a trailer to run a mini split and inductive cooktop (future project I want to do with my girlfriend) and everything just keeps coming back to 24-48v being the cheapest option altogether, including running a bigger inverter for said mini split.when you spend $3-5k on a A/C and Batteries to run it - spending $50-100 additional for wires shouldn't be the issue
I would love a 24V or 48v system,
I am conversing with them through email now, but I'll try and just share all the information on here for everyone to have. So far, this is a very nice unit.Do you mind copying me or sharing the email. My email is rob at rwl. NET
I am very likely buying two once I get a little more info.
Wow, they actually got back to you? I have two emails, a phone call, and questions to a member in another thread to someone that claims to say “my company”, please reach out, and nothing in response.I am conversing with them through email now, but I'll try and just share all the information on here for everyone to have.

More recently, however, PVT modules coupled with refrigeration system have been gaining attention too. Here, the compressor is powered by the PV panel while thee PVT module itself also serves as the evaporator of the refrigeration system. The evaporator cooling effect lowers the solar cell working temperature and improves the PV efficiency. This arrangement can give an even better performance as compared to air or water cooled systems.
Numerical Study of Integrated Solar PhotovoltaicThermal Module with a Refrigeration System for Air-Conditioning and Hot Water Production under the Tropical Climate Conditions of Singapore
Proposed System
The proposed PVTR system produces electricity, hot water and air-conditioning at the same time by integrating solar PVT and VCR systems. Electricity is produced by the PV cells, while the refrigeration system produces hot water at its condenser and air-conditioning (cooling) at a section of the evaporator through a fan coil unit (FCU). At the same time, the refrigeration system also cools the PVT modules to optimize their performance
The results show that attractive electrical and thermal perfor- mance can be achieved with a maximum annual cooling COP of 9.8 and a heating COP of 11.3. The PV e±ciency and power saving were 14% and 53%, respectively.
Premier Products is who I emailed, and they got back to me very fast. The President got back to me first, and CC'd the Vice President to answer my questions, and the Sales manager to get me pricing. Both of them got back to me and answered questions and got me pricing within the next 10 minutes. Me and the Vice President have had a few emails back and forth since.Wow, they actually got back to you?

But, you are right, it does seem to have some good specs and I have found Coachman Galeria videos that seem to prove it to be quiet. Not sure on the power consumption because in the videos, they say ‘ look at the low draw! But the solar is on’
Damnit , turn the solar off and show us what the unit is drawing!!!!!
All a moot point for me as as much as I would like a 12 volt native system, it won’t fit between my solar panels, skyline, and roof vents.
recpro.com seems to only be selling the 12 volt version. It comes from premierproducts.net They have a 48 volt version on their site but they are the ones that have been unresponsive to me.
I think I’m back to a mini split
Max power draw varies depending on outside ambient temp. But its typically 40% less than my existing AC. And 1x PP 48v unit is equivalent to 1x Coleman Mach 15 in terms of cooling efficiency and even in CFM rating. Only difference is actual power draw.What's the power draw for those? Max and typical? Also, in your situation are you saying one of the PP 48v units is equal to ONE of your Coleman units or one PP 48v unit is equivalent to all three of your Coleman units?
I guess I'm trying to understand if you need one or three. I'm assuming all three, for nearly $9,000?
Thanks for reporting back Lt.Dan, this thread has got legs?.Max power draw varies depending on outside ambient temp. But its typically 40% less than my existing AC. And 1x PP 48v unit is equivalent to 1x Coleman Mach 15 in terms of cooling efficiency and even in CFM rating. Only difference is actual power draw.
I would need 3x and that totals to $8085+shipping.
BUT, since they dont offer heating, then I would probably only get 2, and put one in the bedroom, and one in the garage, and then leave my Colman Mach 15 in the living room strictly for the heat pump feature.
That, or rely on heating from little space heaters or my propane furnace.
where are you mounting the outside unit?I'm installing an LG Mega 115v series 12K BTU mini split in my travel trailer this weekend. It will run off my Victron inverter. You can buy cheaper mini splits on Amazon. I didn't find any DC (12, 24, or 48 volt) air conditioners that were cost effective. I can add two more batteries and more solar to my roof PLUS the 115v mini-split for the same or less than trying to use one of the DC air conditioners.
If my rooftop A/C hadn't died two weeks ago I might be inclined to roll the dice and try one of the cheapie units from Alibaba but I just couldn't work up the nerve to risk it, let alone the time it would take to get here.
Do you have an inverter in your set up? If so, maybe you could consider traditional residential mini-splits that run of alternating current.
