New 5th Wheel Trailer Build Advice

[Dontatsu]

I am purchasing a new 5th wheel trailer with my most extreme condition use case being camping in the desert
for Burning Man:

Brinkley G3250 Toy Hauler

3 GE Air Conditioners
50 Amp Service

3 Each Yixiang V2 48v 318AH Battery Packs
1 Each Epoch 12V 460AH Battery
Victron Lynx Distributor 2 each fused
Victron Lynx Shunt
48V/12V DC-DC to the Epoch Battery
All in One Inverter/Charger
T Class Fuse
Appropriate cabling

I am looking for general advice and recommendations for a build of this type.
Particularly I am trying to figure out the best AIO. Case size is an issue so I have looked
at the EG4 6000XP and the Sungoldpower 8/10 KW units.

Ive built other systems but only single phase so Im looking for insights.

Thanks

Those yixiang batteries seem amazing! I plan on getting a pair for my rig.

I'd skip the lynx shunt and go with smart shunt. No Bluetooth and you can't use an aux so with a BMV or smartshunt you can monitor the 12v system voltage as well. Without a CerboGX I don't think you can even use the lynx.

Any reason on planning using an AIO vs a pair of Victron inverters set in split phase?

What generator do you have? Or solar? Even with those batteries you'll only get like 33hours of a single AC (50000/1500). I'd look into the amp charge rate of the inverter and try to max out the genset on auto start. Run it for a half hour a day as needed and never worry about anything

Have you thought about solar for this?

With 2.5 kW of solar, I can run one AC, but don’t have enough left for meaningful charging. Half that is on my roof, half on the ground.

If you have 900 ah of 48 volt batteries, this is 1000 lbs. trailers do have weight limits. You’d likely exceed that with water and the batteries and very little else.

Will the dc to dc converter have three state charging or a constant voltage?

Since burning man is in late aug early sep, you will want to use the ACs, otherwise why go through the trouble of the build.?

I plan on a Cerbo GX. I just forgot to list it. I plan to fill the roof with solar but I currently dont have access yet to it to see how much will max it out. Burning Man should be pretty productive solar wise. I have a Westinghouse Dual Fuel propane/gas 10,000 watt "portable" and the built in Flexpower 5500 also gas and propane. I will likely only run propane.

I will have solar. See reply above. I have a GMC 3500 Dually and I will be within the weight limits even with 1000# of system. I have about 5000# total of cargo capacity and no toys or other heavy stuff.

I'd suggest a Midnite Rosie 7048M inverter/charger.

MidNite Solar MNROSIE7048M Mobile Inverter/Charger 7000W

Shop now for MidNite Solar MNROSIE7048M Rosie Mobile Inverter/Charger 7000W 48VDC.

www.stellavolta.com

120/240V 7kW in single chassis with massive surge capability. 42lbs without breaker box. Made in Washington State.

Does need an mngp2 to program/monitor, I have a hawkes bay 90A and I use the mngp2 thats integrated into that.





The first thing you need to do if you go with an eg4 6000XP is check if the neutral bus bar is properly connected....they've know about the problem for a long time.

For SCCs I like the Victrons and the Midnite Classics are also nice for lower voltage strings. The hawkes bay 90 and 120 and Barcelona 200A sccs are 600V class and not suitable for mobile strings.

My RV's about the same size 40ft but skinnier and I fit 5000w on my roof completely full with angled panels going above the ACs. Even with great angles I get around 3300w here in ohio. I think at burning man but flat panels you'd get similar.

Look into autostarting the generator with the CerboGX. It'll take at best an hour per 10%. You can set it to 20-40% and it'll run for a couple hours if needed. Also can set quiet hours so doesn't turn on at night.

What is your power requirements?

I’m estimating 70 kWh. I’d want 15 kW of panels. That’s 83 square meters with a roof space of 32 square meters. Your real usage will vary significantly.

I estimate 5 kW to run all 3 ACs; about 1.7kW each for 14 hours. You could shut one off to cook the microwave or the hot water.

I have found that I need two ACs in my fifth wheel to eventually cool down. Above 85 outside ambient temp, one AC struggles. Someone actually had 6 ACs to cool down quickly.

If I am close, a single 6000Xp would not work since 3.4 kw is on one leg of the 120 volts and 1.7 kW on the other. I’d feel better with two Victron 5 kVA or similar rated inverters.

I do have a fifth wheel with 13 kWh battery pack and 2.5 kW of panels which can and has run a single AC for 10 hours a day.

You can do whatever you want. 5000 LBS is A LOT of weight to put in.

That would be me My rig's designed to be like OPs and for day trips, festivals, races and such. Boondocking for the day or 4. When its super hot 90+ I learned I need to run 3 ACs to keep cool so if at a festival i'll turn things of mid day to charge up then when walking back i'll turn all 5-6 ACs on to cool it down then they stagger off as temps drop. Now I can use the CerboGX to turn on my 20kw genny remotely from my phone so can turn this on, then start all 6 and after 15 minutes i'll turn off the genset.

I plan to potentially replace two of the GE 13,500 units with 18,000 Chill Cubes. I dont plan to run the unit in the garage space.
I will have to give the inverter size some thought. That's partly why I came here. Maybe the Sungoldpower 10kW unit would fit the bill.
I dont plan to put anywhere near 5000 pounds in it. The power system will be by far the heaviest part, then a couple of bikes, water and food and clothes for a week.

Why the SGP 10kw over 2 Victron 5kw setup in split phase? You're already getting the cerbo and everything so it'll all integrate and you can control from anywhere.

The Chill cube's seem amazing and are reasonably priced.

I installed a chill cube in my current Renegade. I love it.

Ast to the Victron that's part of what Im figuring out. What will best meet my needs in a form factor that will fit my storage bay.

Its possible a 6000 do will run two fusion chill cubes or two standard 13k btu ACs.

I get the impression from reviews I read the the furion chill cube is slightly better than a standard 13k BTU RV AC, but does not deliver 18 k BTU.

It’s been out a few months now, so not a lot of data. I got a quick quote from camping world to install one, and it’s not much more than a standard AC. There’s so many options to get right like ducted or non-ducted when ordering.

I run my current one on a single Multiplus It draws between 100 and 700 watts or so. I can't speak to the BTUs as Im running it ducted in a small space. I got mine from E-trailer and installed it myself. Pretty easy.

would you mind posting a link to this AC or model #?

Also more important, is it quiet inside? Mine sure is not.

15 k btu is fairly standard for a main cabin 5th whelk AC with a 13.5 k BTU in the bedroom.

There’s biggest problem I have with a AC self install is getting it to a roof. I have a ladder, but no other way .

I have a 15.5k Furrion AC and its much colder/powerful than my Dometic Brisk 1 and 2's, I have 13.5k and 15k dometics and can tell the difference.

When I did my ACs I used a tree and rope. lifted it up in the air then backed the coach under the tree, dropped it down and did the reverse for removing the old ones. Before I thought of this I used a rope then from the roof pulled it while someone was on a ladder helping from the bottom and keeping it from scratching the sides. I'm lucky as I can walk on my slides.

I believe they have the AC as a single model then options for the brackets if ducted or not ducted.

No they are two different models.
