Greetings, I am in the information gathering stage of assembling a 50 Amp Off The Grid Boondocking Solar System for my new 45 foot Keystone Fuzion 429 Toy Hauler. I've spent weeks online trying to absorb all of the information I can while trying not to get steered in the wrong direction. I am...

I believe what they mean in that sentence, if you read it carefully, is that 2 of 3 the standard older RV AC's that they mention would have to be on the same leg at 40A, when there is only 50A total available on said leg, leaving little room for anything else to run. I'm sure Keystone knows...

Yes, but I'm not skimping whatsoever on this system. I have a $15,000 budget on the Solar and related electrical for this Fuzion 429, and I'm going to be capable of everything OTG anywhere. That is the goal. Hell, I want bring along one of them Coleman inflatable hot tubs to sooth my bones after...

Thank you so much for the responses! I did have a look at the Gamechanger batteries. I originally thought 4 Gamechangers would be needed, and now I see how three would be sufficient. This will be a cost savings of over $1600 and a weight savings of 70 lbs., and as a toy hauler, every pound of...

Yes, like I had said, the lug connectors in question getting hot could've been made of inferior material and cheaply coated with inferior plating, thus causing resistance; hence, heat. Not all products are created equal. I have seen lug doublers like the one I had linked to being used in many...

Hmm... Don't know why it would get hot there and Chad's first idea would stay cool as it is essentially the same thing. Maybe his amazon link is made out of pot metal and has the wrong type of coating. Another way would be just to jump the connections together at the transfer switch with an arc...

More Refinement.... Since two Victron inverter chargers will be used, the Multiplus II with Pass Through is now not needed, as each leg will have its' own Inverter / Charger. Hello, Quattro's...!!! Twin 24 Volt 5000's more like it. Now it's all finally coming into focus. I can try to squeeze...

I can connect L2 and L1 at the Transfer Switch on my Onan QC5500 alternator legs, because this generator isn't actually split phase, in which the MP II will now handle both L1 and L2 using Powershare to make up for the deficit if any from the Batteries and/or Solar Panels . My Solar/Battery...

I have this Fuzion 429 at home now, and I am getting acquainted with it. I have it on provided 50A Shore power, water, and septic. We have had a few days here in the high 80's, so I did two tests with Generator and Shore power, by which, I ran all three air conditioners on full blast, the...

The latter....I'm getting out there and I'm never coming back.

And this is why I am here doing what I'm doing, which is gathering and drafting a plan with the help of input from others. I do not want to piece-part-retrofit-change anything. I want to design the solar set up to be solid, robust and optimal from the get go. I'm sold on the Victron MPII 2x120...

After a night of research and reading, and now that the Victron Multiplus II 24 Volt 120 X 2 50A Pass Through Inverter / 70A 24 Volt Charger is available, I am now set on building a 24 Volt System. The benefits are many: smaller wires, less cost, more efficiency, less resistance / heat power...

Alright, It seems for practical purpose on a system as large as I want, which is the biggest I can possibly fit on my Fuzion 429, that a full 24 volt solar and battery system would be more beneficial in many ways. The problem therein is about a product that isn't made or released yet so it...

What do you guys think about the Victron MultiPlus-II 24/5000/120-50 230V Inverter/Charger for a 24 volt application such as mine? It's not set up for USA shore electric standard.

I'm not.... https://www.victronenergy.com/upload/documents/Datasheet-MultiPlus-II-inverter-charger-EN.pdf Victron Multiplus II 24V/5000W/ 120Vx2 @50A Pass Through Inverter Charger. But alas, it Looks Like I'm going to use TWO Multiplus II 24V/3000W /120Vx2@50A Pass Through Inverters Chargers...

Chrisski, that's a pretty good system you got there. Are you finding you have enough power and storage, or are you needing more?

Yes, that goes without saying. I would like to get at least two Air Conditioners running; three would be a bonus.

Thanks, chrisski. I do not take delivery of this Keystone Fusion 429 until the 22nd of this month, so I cannot do a real time audit as of yet. It's 45 feet long and I'll be able to pack it with solar panels. I may not get all three AC's to work, but at least one or two. What I meant by 50 amp...

So, there aren't any 24V/5000 120x2 Multiplus II's available yet for USA electrical standard....?

Awesome, Jen!.....Thanks!

How many Multiplus II's can be strung together? Are they set up in a Master/Slave configuration?

I keep hearing conflicting information. So, it is available for North America now? If so, now I will have to weigh the pros and cons of going 24 volt. Although it can do 120V/240V, It's only 120v in Inverter mode. The battery wiring gets more complex, along with the need for a different DC to DC...

WOW! up to 3 units in 3 Phase.....This could get very elaborate really fast. https://shop.pkys.com/Setting-up-parallel-and-split-phase-systems-using-the-Victron-MultiPlus-and-Quattro-inverter-chargers_b_161.html A 3 Phase 24 volt system would be too complicated for this application I think...

Beautiful...! I need to find some sort of design app to do my own plans here. Okay, so everything here DC is still 24 Volt, and then a 24 to 12 Volt DC to DC converter would come off the 24 VDC distribution panel, to then feed the RV's 12 Volt DC Panel. I like it. Next would be choosing the...

Bottom line of the point of the post.... Three Air Conditioners running at the same time for a combined 32 Amps Total. (Not 55-60 Amps) Point being, 3 "normal" RV air conditioners would drain the largest RV Solar & Battery System inside of 3-4 hours, whereas the Omni-Chill System Technology on...

Excellent! This is why I am here....for the experience and expertise. It saves much waste in time and money to get the pre-guidance of the "been there, done that" people. When one switches up to 24 and 48 volt, albeit less wire size and lower heat load resistance loss, doesn't the system tend to...

Hmmm.... Three Air Conditioners may not be a problem.... THE POWER OF OMNI-CHILL Unlike any other A/C system on the market, Keystone RV Company’s™ EXCLUSIVE Omni-Chill® air conditioning system allows three air conditioning units to run simultaneously, allowing the RV unit 35% more cooling...

Thank you! Okay, didn't know that, as I don't take possession of the Fuzion 429 until the 22nd of this month whereby I can really get into the specs. The lower video makes sense in that all Chad did there was combine both sides of the alternator on the Generator before the transfer switch, so...

Yep, sorry, not interested in doing this at this time. I understand the amazing efficiency of mini-splits, but I'll have quite enough on my plate this year alone to get done. I'm not an air conditioning hog anyways, and where I want to roam out West is dry; further South in Winter Like Sand...
