12K Btu 120V Mini Splits

[windtrader]

LOL this morning I have the Aquahot on,light jacket and long pants , damn 53F and 5% humidity is cold ,AZ you got to love it a 60 degree swing in 125 miles

Clifford, What options are there for RV in Flagstaff area?
Going from Oakland to Concord, about 15 miles, during the summer, the temp goes from 70 to 100 in 15 miles, in the tunnel at 70 and a mile later it is 85 coming out, then a degree a mile, really amazing.

Plenty of RV,State and Federal parks around Flag,I like Williams better plenty of free parking there and the climate is the same

That's the advantage of the Penquins, they are the only roof A/C that uses a squirrel cage blower for the condenser air-which was easy to duct with a 6" hose to the outside through the floor. Good Luck, TomC

There is lots of forest service land, that people boondock, between Williams, Belmont and Flagstaff. Yesterday we were dumping pine needles at a green waste dump and there were plenty of boondockers pulled off in some graded spots, some even just off the road. Beware of forest thinning, you don't want to be awakened by chainsaw and falling timber!...

That is very interesting and handy to know, thanks Tom.

I ran both of my mini splits yesterday on one 2000W inverter. It struggled to get the second one started althgouh the voltage did not drop much at the inverter. I currently have a 50' 14ga extension cord hooked into the panel providing power, so there is a bit of drop at the panel. After about 10 minuets of running the inverter started making a low voltage tone (Battery was not fully charged.) So overall a good test.

The inverter is a really crappy ebay piece of junk I bought 10+ years ago. I dont think it truly can put out 2000W. I have tried to use it with other stuff and its almost never worked. The modified sine wave is really distorted, its junk. But even junk was able to run both units. I am going to find a low cost 3500W split phase with a transfer switch build in and that should be fine. I'm trying to stay in the 24V range.

Picture of the bottom of the Penquins on the plywood stand I made with the addition of ducting.

Tom, taking a closer look at your setup - I'm assuming that the photos are showing the evaporator ducting. Do you have photos of the condenser ducting? Your approach has got my attention! Thanks

Do you think a Magnum MS2812 (2800 watt) inverter would run those two mini-splits? Just curious.

[jap42]

2800 should do it. I think its about 900 running each. Those don't have a lot of surge capacity so it might not have a lot of extra for anything else.

I just ordered an aims 3000W pure sine wave inverter. I will update when I get it in.

[dtcerrato]

There are 12K mini splits out there that are drawing 750 watts - time & technology march on... Thanks

I have 2 x 12 k split units at home and they both run off of one 20 amp 120 volt breaker and have never had the breaker trip . At first I thought if by chance they both started at the exact same time with the in rush I might have a problem . But it has not happened in the 10 years they have been used ( both heat pumps now ) . One unit is a 16 seer unit and the other is newer and is 20 seer unit . The newer unit is 3 years old ( replaced a 10 year old just a/c unit ) and the heat pump will work as low as 15 f . So I do not think you will have any problems running 2 units off of the magnum . But I would spend the little extra money on a more efficient heat pump , Minimum 20 seer or better

I was at Peterbuilt in Bosie having a full service on our RV they were installing 12v AC and heating systems in some new Petes called Artic Breeze.  The 12v model was 7200 BTU and the 24v model was 12,000 BTU 500w neat little system comes with Ion batteries. a charger and  when needed and had a 300CFM fan, price was $4000.00 + that would be a killer for most bus nuts.I don't know how they worked on AC current they installer said they worked on both,they are split

If they're anything like the ones on my Freightliner they probably work well. I think that our units are DC only, running on 12vdc. Easily keeps the sleeper at 65F with outside temps pushing 100F.

Any brands of the 12kW mini-splits you folks are happy with? Thinking about swapping a rooftop for one since the energy draw is so much less which is a real issue when running AC off solar.

I have been running a mini split on the back of my 102a3 for 3 years now.  It works great until the temp gets up to 95 or so.  At that point, with the way my bus is sectioned off, I can't blow enough air up front to cool that area.  Other than that it has heated and cooled my bus well.

So I am clearing out the bay where the over the road air stuff was and have a new mini-split to put in there that should arrive in the next couple of days.
The on I have had for 3 years is a 12K btu, 110v, Air Con with inverter technology.  I bought it now for $450.  Now the same unit is well over $800.00. 

So I bought a 20 seer, 12K, 110v, Daizuki heat pump with inverter technology for $550 to put in the bay I am clearing out.
