I came to this video for the shot at frame 29:57 and you folks didn't disappoint! Do you ever get tired of people going on and on about how good your tutorials, schematics, plans, equipment, etc. are? If not, they are absolutely fabulous. Thank you!!

19:35 or so is one of the best parts of the video and should be listened to two or three times.

Easily the best how-to videos on this topic out there. Really well done!

Those nuts on the solar array tilt mounts look like real drop hazards, especially on that many panels. I'd replace the nut with 1/4-20 stainless nut rivets in the aluminum angle for a nice clean installation and fewer lost fasteners.

Great job & great video ❣️ You guys are like Doctors at these mobile power systems. I'm impressed with your kits, your spreadsheets and all your videos. You guys help millions of people! At 69 years old, if I can make a suggestion: If you would allow customers to choose their batteries, I think you guys would have to hire installers because your business will be so busy. God bless you ‼️

I love watching the installation of these electrical systems. I wired up a small scale 600w solar system with 540ah of gc3 batteries in my small cargo van, and I can tell you that it was as fun as it looks to be. I owe a lot of thanks to you, Nate!

Great video. That's a very clean install. I can tell you guys are pros. You are very good at explaining things too. We just found your channel and subscribed. Five years ago, we took an early retirement, sold everything, bought an older MH and hit the road FT. It was the best decision we ever made. We discovered that we enjoy boondocking and it helps stretch our budget too. We quickly learned the advantages of solar and decided to build our solar/battery system in 2 phases, a 12v system for our basic 12v DC needs and a 48v system for our 110v A/C needs. We started with a pair of lead acid golf cart batteries and custom built a 620-watt liftable solar array mounted on the side of our motorhome. We lift the array to the optimal angle to improve their output by 20-30% vs flat mounted panels - even more in the winter, when the sun is lower in the sky. It serves as a nice bedroom window awning too, practically lifting itself to the desired angle with a couple gas struts, and it's easy to clean with a windshield squeegee, standing safely on the ground. This set-up, while far from optimal, allowed us to boondock till we could afford to do better. We finished the 12v part of our build last January, with the addition of a 560ah LiFePo-4 battery that we built with 8, 280ah "A" grade prismatic cells. We use a Heltec 350amp BMS, and a 5a active balancer to keep the cells synched up. We typically use less than 20% of their capacity daily giving us enough reserve capacity for about a week of bad weather before we have to run our generator for charging. It cost us less than $1,500 to build this 560ah 12v (7.1Kwh) battery (roughly the equivalent of 2 Battleborn Gamechangers), including the high amp BMS and balancer. We chose these cells rather than a pre-built battery because they fit perfectly under the steps of our MH where our old pair of GC-2 golf cart batteries used to reside, saving 35lbs too. We insulated the battery compartment, cut a 1" hole in our step risers and installed a tiny computer CPU fan to keep this space at close to room temperature, so we don't have to worry about the BMS shutting down charging if they get too cold - or their life reduced from getting too hot. We use an 80A Progressive Dynamics LFP converter/charger, a 1,000w Renogy PSW inverter (to run our TV, PC, ice maker, etc.), an Epever 50a MPPT charge controller and a Lnex battery monitor/shunt. This entire 12v system cost us under $3,500 to build and takes care of all of our basic off-grid needs except for air conditioning and microwave use. By mounting our solar array on the side of our MH, we left the roof free to rack 8, 550W Sungold Power solar panels (4,400 watts) down the length of our 35ft Class A, 15" off our roof, above our AC, fan shrouds, etc. They will cover the entire roof, providing some nice shade with plenty of cooling air underneath, further increasing solar output and reducing the heat load on the air conditioners too. We bought them for only 51 cents/watt shipped to our door! We're assembling the components for this build now. We bought our aluminum racking material in Yuma, where we're wintering over this year, for under $400, which is the best price we've found. Our solar panels, wiring breakers, etc. arrived 2 weeks ago, but we're taking our time to get everything in and installed over the winter. At 67 yrs old, we're moving much slower these days. Our Sungold Power all-in-one 48V, 5,000W, 120V PSW Inverter/100A charge controller/battery charger arrived last week. Our 48v battery bank will use 16, 320ah grade A prismatic cells which only cost us $1,726 from EEL batteries. So together with our 560ah (7.1 Kwh)12v bank, we will have a total of 23.5 Kwh of batteries onboard (almost 7 Gamechanger's worth) - kept charged with over 5,000 watts of solar. We installed another powered roof vent in the hole that our 24 yr old rear 13.5k btu rooftop Dometic AC was removed from. We're replacing this AC unit with an EG4 28.5 seer-2 plug and play 12k btu mini-split heat pump. This second phase will provide 24/7 off-grid air conditioning, supplemental heat from the heat pump and allow occasional usage of our rooftop mounted Furrion AC in the front of our MH during peak afternoon hours, as well as give us whole house 120v ac power. We'll soon have total off-grid electrical independence on a budget we can afford, reserving our generator for back-up use only. Take care, we hope to see you down the road!

This is the best video I've come across for installing Victron, solar, and batteries in a RV. I never knew I could use the Orions to bump the voltage up and charge the 24V, I thought they were only step down. Thanks a lot for the video!!

I absolutely love your videos and they are great. You guys are awesome beyond words!. Thanks to your previous Truck Camper video, I was able to install a complete system entirely *on my own* in my truck camper and I couldn't be happier : )

Thank you guys for your very detailed videos, step by step from start to finish. I've been watching some of your videos, it's very simplified and easy to understand in every step of the way. Love you guys from the beautiful country of Papua New Guinea 🇵🇬❤️✌️🙏

After seeing what a neat job you do with wiring your systems, I was shocked at the rat’s nest the manufacturer of that RV left behind the OEM breaker box.

Excellent video! I appreciate the detail installing each component! We have an Alliance 5th wheel and im planning a similar upgrade next year. This will be a great resource.

Dude, I'm addicted to your videos. I hope one day I will have equipment like this 😄

Such a great instructional video. Thank you for taking the time to fully explain each step.

super clean exactly how id do it

Wow, so professional, I really enjoyed watching your install. Thank you very much for your time and effort in describing and making this video. Great Job Thanks again

This is one of my favorite videos of yours, and I referred to it often when building my own fifth wheel system. The one thing I'll say that didn't work out for me was the OEM Splice Kit. I ordered this from you, and was actually looking forward to using it to splice together my 120V AC lines. However, when I went to use it, I found that the connection bars that you sent were not robust enough to hold the thick 6/3 Romex cable that I was using (my Allliance fifth wheel uses 6/3 Romex from the 50 Amp connection to the breaker panel, so I used the same cable to go to the Victron Muliplus II and back to the box again). I tried and tried, but those connectors just couldn't seem to hold those stiff wires. Not to mention, the plastic mounting box interior mounting screw holes also failed with the stiff wire pulling on them. I ended up buying a junction box, and splicing together the wires that way. Maybe this is partly on me. I wish there was a more robust and stronger solution that allowed those wires to just be connected together, almost like a big Wago 221 connector. Anyway, other than that, everything else worked like a charm. Thanks!

Best of the best you guys!

Thank you for the video helped me for when it comes time for my solar project

Wish you had a video for a 50 amp system on 12 volts

Very cool!! like watching your video's! Even tho I have been an electrician for over 50 years I find this type of install very interesting. Thanks for taking the time to record, edit and share!

I wish this was a Quattro install. It seems a camper that big would incorporate a generator to the system. My 2024 sprinter 170 is being delivered in December. I’m thinking about installing a Quattro. I will inquire much more when I get it. Keep up the good work you two. Great stuff. ⚡️🔋🔌🌞📡🏔️🚐

Fantastic video, I am going to do this in my sailboat that I am working on upgrading, and this will be at great help

This is actually very informative! Great install and plenty here to learn from. Thanks so much for sharing!

Looking for the Pin Terminals used in the video to connect the AC wires to the MultiPlus2. Nothing on your website. Excellent video learned volumes

Thanks you 2, learnt so much from you. I didnt know we could put 2 dc to dc chargers. I only installed one and it does give out the 30amps rated weird. But love my system. Its identical to this set up but 12v

Thank you so much for these videos. I wish my truck camper installation was as clean as yours! Great job. 😎🤓💜💚CA❤🤙

Just diving into all this myself, great videos my man 🤙🤙

Great videos, enjoy all of them! Recently read how a few 5th Wheelers are changing their Victron & Battleborn out for the 58v Volta system. Have you looked at the Volta system, appears to have advantages to explore.

7 minutes in you forgot to show a link to the playlist you were talking about, great video btw!

First, I really like your content, videos and presentations. I do have one comment that on one practice that doesn’t make sense to me. Why splice into the 50a service line. Another connection can just add a potential point of failure. I think the right way is to pull a new 6/3 line from the shore power plug directly to the inverter and then directly to the service panel. Therefore avoiding unnecessary connections. I do have a BS in electronic engineering so I know a little about the theory and best practices.

This was a fantastic video. Thx much.

Great information. You two rock. Thanks Don

I like the cable raceway I see in your videos to clean up the bay wiring . Do you sell that on your site or have a recommendation for a source? Great job as always on this rig.

this must have been a fun project for you

I made it approximately 20 minutes into this video and realized I still have a little immaturity left 🤣🤣🤣🤣

Your videos are really good, I like them a lot, just one small observation, you should not use lock nuts to secure the battery cables to the batteries, those cables get hot and the plastic in the lock nut can burn out with the time, you'll get a lose connector and that'll be a fire hazard.

Where did you guys get the blue cable tray ?

As usual an incredible installation and how to video. Just a comment, I suspect the owner will tilt those 12 panels just 2 or 3 times and then leave them flat for every remaining trip. Too much work to tilt them each time plus the camper has to be facing the correct direction.

I did not understand the CONVERTER Breaker box thingy. Why did she invalidate the A/C and not the labeled CONVERTER ?

Great video

You said you were not gonna do the demonstration on the dual Victron inverters with all the goodies that go with the install from battery hook ups to the charger controllers and cerbo …well I feel you should. It’s a good watch with you guys to Do The complete installs, to chase the other videos I’m sure helps you guys with the views, but idiot proof is way better. All in 1 is better. Even taking the time to do the desk set ups as 1 video then to do the complete install as another video.. especially 50 amp set ups because that’s what this product is designed for and most want to watch from beginning to end. Maybe doing a programming of the system as a separate video is something helpful

Thank you for all of the super helpful videos! You guys convinced me to use Victron in our skoolie build, and your store has the best prices. Are you guys considering doing a skoolie install video ever?

Lo,be your videos, have you done any truck campers such as a Host, Lance, Arctic Fox? Would love to see your innovation in such small spaces and minimal roof access. Thank you for the videos.

Great informational video. Thank you! One thing I am unclear on is the 12volt power wire inside the 7-pin connector from the truck to camper. Not knowing how it was wired into the camper originally, did the camper wiring need to be altered such that it only connected to the 12 volt battery ? Thank you again for consistently creating great videos.

Hi there, watched a few of your guys install videos now, and purchasing a bunch of your wiring kits, noticed on this video you guys installed a battery terminal fuse right onto the battery, my question is why this was done on this install but not on your other 30amp 12V trailer install. Thanks!

Hello, very impressive. Thank you. One question... Why the chassis ground from the Multi and the MPPT looks like the same size as the powering. Is there a reason why it's so massive? Best regards Robert

That make my setup look like a toy

I SELDOM see MOUNTING RAILS like they do on houses. Random mounting anywhere leads to many points being on unsupported areas which leads to leaks. If you put a cheap mounting system rail you can dril into 2x2 FRAMES and then mount your panels on the RAILS, not on unsupported non frame areas. ALSO you can move, repair or replace panels without further damage to roof

When you hooked up the dc/dc charging to the truck battery. You should have gone to the lug not the clamp tension bolt.

What is the wire loom you put around the alternator charging wires? Is it available from your store?

Another very good install video. I wonder why the need for the alternator charging, with 2400w of panels on the roof and the option to run a generator if needed? I have a new 5th wheel with about as much open real estate upstairs, and a plan will be to add real usable solar, so this video is great timing. Thanks to your team for this guide.

were is the fuse for the heater wire?

Great install. Shouldn’t there be some cable clamps on the splice box? It is high voltage and with all the movement in an rv you would want them as secure as possible.

Very nice and clean install! I’m glad someone else is doing 24 volt battery bank. Question, where did you get that blue cable management channel?

Thank you for another great video. We just traded our Grand Design in for a Redwood 4001 and will be doing this exact install with the exception of a possible second MP II 2x120 in parallel in the future. The Redwood has a Xantrex 2000 watt invertor tapped off the 12v batteries and feeds the TV, frig, and 5 other receptacles. Would you leave the Xantrex in place or remove AC output and tie them into the Victron AC output? The RV also has an Inteli-Power 4500 Series Distribution Panel with a built-in converter to charge the batteries. Should I wire in a disconnect switch to prevent a circular charging path?

Excellent video and a great refresher as I install my 1280w system on my Arcric Fox 5th wheel. One question. I don't remember seeing the installation of solar panel breakers. Did you not use them going into and out of the MPPT? Thanks for the video!

Hello Nate, I have a 42' ft Class A Diesel that I would love to do exactly what you did there. It already has a factory installed 100w solar system that I want to convert into a 24v just like you did. My only concern is if I will need to upgrade the alternator and also, it has an emergency start system on which if the engine battery dies, I can use this button to jump the house battery to give juice to the engine battery to start. On that case, what would you do? Thank you for the work you do which it is to be admired and thank you for helping all of us out. Best,

EDIT: I just realized that this breaker probably has a line and load side which means it cannot backfeed.... The breaker is a one way breaker @33:33 Can you please clarify how the 150A breaker prevents backfeeding through the DC/DC step-down converter? Is this breaker supposed to be manually tripped when not needed? Shouldn't there be a diode between the 24 volt wire and the orian input or is this built into the orian converter?

Good video! What output voltage the Orion 24 to 12 converter is set at? For general 12VDC usage, 12.6 seems like a good number, 13.8 is float for batteries, then 14.2 is charge. Or, do you leave the voltage low (something like 12.8) so it is effectively an unmanaged trickle charger?

Great job with this. Wish you were local. I would hire you for my home install. As for tightening cables, wouldn't it be easier (and better) to just use a "Stover" Nut instead of a lock washer?

Any issues with mounting the multiplus horizontally? I would have to mount this way as well

I looked on your website but couldn't find it - is there a wiring diagram/parts list/blog post for this 24v 50a install? I found the 12v version, but not the 24v... Thanks for everything you do!

Great video - very informative and I like the details you show. I do have one question, given the quality of the install you are doing, how come you are putting bare wire into screw-down /binding posts? This is generally not recommended as the bare copper can come loose over time. Ferrules are the correct approach and you do use them in a few spots, so I wonder why you don't use them on all the bare-wire ends. A ferrule crimper and ferrules are a relatively low-cost item considering the overall cost of this system.

I'm currently hooking my inventer/charger up now (multiplus 2 12/2000/80) and have a question. Wouldn't there be a problem hooking the chassis ground to the negative bus if there's an AC fault in the inverter? Wouldn't that create a point for AC/DC to intersect?

That woman is like a hybrid of "D" from Always Sunny and April Margera.

With 2400w of solar in the pnw, he can charge his iPhone to full annually! 😂

is it possible to make a portable power bank inside a milwaukee packout and be connected back into a vehicle that has anderson connections with solar on the roof and cables to batteries

Should add in the description how much the cost of this whole set up was minus labor. Same with the other setups so ppl can get a general idea of costs easier. Gotta be close to 10g

Awesome video..super clean installation. Would you be interested in the installation of my solar panels system on my Grand Design 397ths

You guys do the best videos and have great tools and instruction on your site. I'm planning a 24 system and will likely buy the kits from you for most of the wiring. Question: did you put ferrules on the solar isolator wiring? It looked like you just stripped and connected. Any reason not to use ferrules?

Hi Nate. Again an awesome and informative video You mentioned you left the factory battery in to run the other electrical systems like hydraulic jacks etc. Could the Victron system not provide the power Thanks again

Just got a multiplus II feom you guys. My AC connector blocks only have 3 wires each, even though all the documentation shows 4? AC out 1 and 2 and a single AC in, as expected, but each connector block only has N, PE, and L terminals... Wtf do I have here?

has the video about doing dual charger/inverters been released? cant find it

A thought, why not cut the ferrule end to shorten the shunt power? Keep a butt connecter out of the system.

I am very new to this and wondered why you did not go to 48v?

Nice details through out. Both of you are so good at explaining things. I have a question about the pre-solar wiring. What is the size of the existing solar wiring from roof gland to pass through? Did you use 24volt panels then? I'm surprised factory was enough. My experience is that the factory roof solar (on my 2018 Arctic fox 25w)) is too small to handle as many watts as I want (1200w), and I don't want to do a pure series connected system....in a case like mine, Do you end up running A new drop through the front cap?

Great video.... I am afraid to ask how much this install costs but its nice to know that Victron has all the hardware to get the job done... Was the owner planning on running AC off solar?

Could you do dual 24/12v x 70a converters in parallel instead of keeping the existing 12v acid battery?

When on the 50A shore power why does it show all the power on L1 and just transient wattage on L2?

Quick question...I have a grand design solitude and am looking to install basically the same system. But not 24v...but 12v. Keeping the stock house batteries...I dont need the 24-12v converter. Do I even need the house batteries? Or how would it be wired.

I could be wrong but when labeling the inverter so no one would cut it on is it me or did you cut off and label the ac breaker ? I thought you were cutting off the inverter?

What Rubberized coating did you use for your backer board?

Why do you use ferrules on everything but not the PV wires?

At the 25:40 mark, the splice box, with terminal block and rail, is that an assembly you sell in your store, or how do you source it?

Do you guys work with a company that packages hydronic floor heating systems?

So my question is how to determine the wire gauge for the various connections you have here. I see the primary DC connection from the Multiplus is 4/0, but many of the other wires look to be 1/0 or something else. Also, if we needed a “custom kit” made up, can you supply that? For example, a kit without the solar panels or batteries (already have both of those)? Thanks….

I really don't understand why you would spend so much on solar when you can spend 1k on a propane generator (you are already going to have propane for heating water) that puts out 12k watts. If you are super worried about outages you could have a powerstation till you get back to town to refill.

Hey Nate, I'm just finishing a nearly identical install. Is there any reason to not wire two 24/12 - 70 converters in parallel instead of keeping a heavy lead acid 12v battery? It seems like getting rid of that weight/maintenance is the way to go.

If I was installing the system in this video, would i need the smart dongle to program the multiplus II?

I have 6x40v solar panel i need 20 amps charging how to connect with solar panel to charge controller please suggest me Thanks

Shouldn’t you have mounted the Anderson connector in the truck bed facing down instead of up? That would keep rain out when the truck is used without the camper.

The bottle neck of this whole system is the battery bank. On a cloudy day, they wont be able to use their solar much because of the small battery bank. Why would you spend so much money and not get a sufficient amount of battery??

What are the advantages of doing 24v 3000w vs dual 12v 3000w inverter/charger ? Seems a dual 12v system would double inverting power for a rig that size.

I was wondering when you programmed the SCC for 100A but it's an 85A controller. It that because of the 24V system and that's what the battery limitations are? I was also wondering about the 150A circuit breaker for the 70A converter. It the converter programmable to charge that house battery? You placed that circuit breaker upsidedown and I have noticed that they often have a battery and a load side but since the flow is towards the battery instead of the usual configuration, which side did you use for battery? I'm assuming placing it upsidedown was deliberate.

How did you make the 3/4” rubber back plywood?

Hi guys...love your channel...I watched how you connected the disconnect switch to the linx distributor using the linx adapter(copper bar). I want to connect my disconnect switch straight to the positive bus bar on my linx shunt but the bus bar has a M8 hole and my disconnect switch has M10 studs...can I use my drill and increase the hole size on the positive bus bar of the linx shunt from an M8 to M10 so I can connect my disconnect switch directly without the need for the copper bar adapter?? Or is this not recommended? Thanks...Paul

Hello, firstly great video and as always very informative. One question as it will relate to my future install. I see you mounted the Inverter charger horizontally and on its side (if that makes sense). I read this is not a suitable mounting way in my research as there are transformers which become suspended by the case. Have you had any issues doing this type of install. I will be using a Victron 48/3000/35. Thanks Simon
