Installing the Victron Multiplus II Inverter to Power our 50A RV Off-Grid | RV With Tito DIY

[@RVwithTito]

Did this video help you out? Buy me a beer🍺by going to rvwithtito.com/victron and using my preferred supplier for your Victron gear and to rvwithtito.com/battleborn for lithium batteries. Cheers! (BTW: This was NOT sponsored so every bit of support helps)

[@bobmakow55]

@rvwithtito Brian what accessories do I need to order with the Multiplus II

[@RVwithTito]

@@bobmakow55 That is really going to depend on what additional Victron equipment you choose for your system. Interface cables will probably be needed. At a minimum you should get a USB interface cable so you can program the Inverter from your computer.

[@jeanniecalo5123]

*A quiet **Generater.Systems** , love the dual fuel capabilities, camper is 50 amp but the adapter helps and found it still handles the load. Haven't taken a camping trip yet, that's in a couple of weeks. Will see how well it does over a long weekend.*

[@truongnguyenquang93]

We have used the kzbin.infoUgkxOTeIs0vv4_9B5hsmnLsk9r930uDQLu_Y for probably 30 hours with our camper and it’s been great! The noise level is really only noticeable when running the AC and other appliances like the microwave, hair dryer, or coffee pot. It’s not huge like other ones and it has wheels so even at 90lbs, I can move it!

[@campnut6076]

You explained the inverter better than anyone I've listened to yet. Great video Brian.

[@RVwithTito]

Wow. Thanks!

[@petekane2501]

Take a picture first. Very helpful tip for the DIY crew.

[@earlhunt2815]

Brian, I've used several of your innovative construction mods: flexible panels with t rails, aluminum angle cages for batteries and others. In 2020, I went with an entire Victron system for my class C Navion: 640w on roof, 400w Aux on ground, 4 MPPTs for max efficiency of shading, DC to DC converter, and lots of new increased gauge wiring to meet safety. Then installed the 12vdc dual compressor NOVAKOOL refrigerator. We're 30 amper So went with the multiplus 3000. I've not had a moment's problem and Think Victron is the gold standard for RVs and sailboats.

[@RVwithTito]

Nice job! I agree with what you said about Victron. Once you go blue you don't go back. You just keep adding more :)

[@jerryhoxsey6467]

Finally a straight forward explanation of how to set up whole house inverter. Now I am ready to do this. Thanks

[@RVwithTito]

You got this. Good luck.

[@CartersTrail]

I initially used the Victron 3000W and AM Solar "Smart Phase Selector" for my 50A RV and I've had nothing but problems over the past year. I would constantly lose one side of the panel and at times, both sides. The two were not happy together. I was so happy to see Victron release this new model that I immediately purchased it and removed the extra component. You made a great choice.

[@RVwithTito]

That's also what I've heard from an installer friend about the phase selector. Thanks for confirming. Agreed....this inverter is a very welcome upgrade. I'm glad I waited.

[@jamesmason7124]

Hello from the high desert of New Mexico USA 🇺🇸. Great job Brian on the installation. That's the inverter that I want to get for my 1967 GM TDH-4519 city transit bus but I just don't have the money for it and my old AGM batteries took a dump on me so I really need to get batteries first because I live in my bus full-time and don't have any power when the sun goes down. Keep up the good work and stay safe and God bless you and your family and America 🇺🇸

[@RVwithTito]

Yikes. Hope you get your battery situation taken care of. We're in AZ and its still pretty cold at night. Stay warm.

[@yairhaim4191]

Probably the best video description of the Victron Multiplus II - absolutely great!!

[@RVwithTito]

Thanks. I appreciate that 👍

[@melc1008]

Cannot agree more. Thank you for taking the time to walk through step by step in your shop and out in the RV. Will you be installing surge protector before your Mulltiplus II?

[@RVwithTito]

Thanks. I'm rarely on shore power, so I picked up an in-line 50A surge protector instead of a hard-wired one.

[@markmelvin3547]

Great to see your video. I'm heading this way based on a couple of videos from @AllAboutRVs. This is a great solution for our class A to power the entire coach with the single inverter. I'm pairing it with two Vatrer 460 AH LiFePO4 batteries. Thanks again for all the great information!

[@RVwithTito]

Glad it was helpful! Good luck with your project. Epoch has a couple good 460Ah LFPs as well with all the bells and whistles (including Victron communication). I'll be reviewing them soon.

[@Trevathecleva82]

​@@RVwithTito I have an epoch And it shipped broken, customer service doesn't return calls. Luckily I was able to take it apart myself and found it was just a loose cable. But will go with LiTime or something else next time.

[@offgridcitycouple5695]

Such a well made and easy to understand video, thanks Brian for the awesome content! I've been looking through a bunch of resources to try to understand how this device works but no one seems to be able to explain it in non-electrical-engineer terms. Thanks again :)

[@pauloconnell7668]

Excellent job. Worked electronics most of my 80+ years and you did a great job of simplifying things.

[@RVwithTito]

Thanks! That means a lot coming from a pro :)

[@AllAboutRVs]

Great explanation and what a great setup. Looking forward to seeing the final system.

[@RVwithTito]

Thanks Jared. It's a great inverter as you know :) and easy to setup. Your videos about it were very helpful as well. I'm working on getting the rest of the videos edited and published. System is working great.

[@logun1970]

Just started this journey for my 5th wheel (ie meaning just started researching on how to do all of this DIY) your explanations have been great. Really appreciate this content. Thank you for sharing.

I like how you explain things. Excellent video. I just ordered one and now I am confident I made the right choice.

[@RVwithTito]

Excellent. It's been a great inverter so far.

[@rossbagley9015]

This is exactly the device I want for exactly the same reasons. Thank you so much for the clear explanation of what it's doing and how. Now to figure out the solar part.

[@RVwithTito]

Glad to help. Best of luck with your projects 👍

[@farmdoc9252]

Nice work and explanation Brian. Watching your videos has helped me with a lot of my RV projects. I had weight limitations so went with two 100 amp Battle Borns and a Victron 2000 inverter for our 30 amp RV. Works like charm and my wife is happy with her coffee when boondocking. Will go with something like your new set up when we upgrade our 5th wheel in a few years. Thanks for paving the way! Happy New Year!!

[@RVwithTito]

Your welcome! Happy New Year to you both. Enjoying my coffee in the desert right now :)

[@stackerothings]

Wow, I had no idea that this install would be that easy. Very informative video. Thank you!

[@RVwithTito]

You're welcome. The key is getting familiar with your current system first.

[@blackiron33]

Brian, as always, you can take the technical aspect of your RV upgrades to a lay-mans understanding. Thank you for all of your videos, I look forward to seeing your next project. Also, thank you for the Solar downloads that you have provided on your web site. I installed a 400 watt solar system on my RV two years ago, and it works OK, but, I do want to upgrade to lithium batteries and more solar. Now I can compare that to your solar diagrams.. and feel confident in my upgrade. Take care, wish you and your misses the best.

[@RVwithTito]

You're very welcome. I really appreciate your feedback. I'm glad the videos have helped you out. Best of luck with your pending upgrades.

[@JeffWellsD]

I just installed the same inverter. Took my first trip last week with it. So far I love it! Be sure to install the temperature sensor and turn on the function to stop charging during freezing temps. To do that, you have to turn on lithium battery mode. Can't wait to see your final setup.

[@RVwithTito]

I did program the low temp cutoff. It's using the temp sensor in the Smart Shunt which is located right next to the batteries. I also have a high-temp switch on a fan behind the inverter to pull hot air out when it gets warm in there. Thanks for the suggestions.

[@terryhaynes1596]

I too installed this inverter and 712 and color control. My BattleBorn batteries are inside the heated fifth wheel. So I didn’t enable this setting. The likelihood of them being that cold is very rare especially if you live in San Diego. Also battle Born batteries BMS will protect them from cold temperature charging. The 712 will report the battery temperature via the color control or phone app. So this setting doesn’t always have to be set. Depends upon your installation and camping style. I guess it couldn’t hurt.

[@thesplinteredfinger]

Thanks for explaining, starting to make more sense to me!

[@RVwithTito]

Great! I'll probably do an update on this setup soon.

[@TheKargs]

Excited to see this series. It has always been fuzzy to me on how to accomplish this and properly interface with the other electrical systems on the RV. Looking forward to your next video.

[@RVwithTito]

Great. Hope this helps clarify things.

[@donholcomb4060]

Just about to install the same inverter in my Newmar, Dutch Star. What an upgrade, the hybrid function and ability to pass thru is awesome. Thanks for your help awesome DIY videos!!

[@RVwithTito]

You're welcome. Good luck with your install.

[@stewartmhyre1528]

One of the best install videos I’ve seen. I also liked how you pre-wired the battery input and output before installing the inverter. Can’t wait for the next video. We have a Winnebago Vista 30T and would like to do a very similar set up.

[@RVwithTito]

Awesome, thank you! Yes. It's much easier to set it up ahead of time if possible...especially this time of year.

[@CozyLivingMachine]

That's probably the best explanation I've seen out there! Victron should hire you to do some of their videos (their site is terrible!) I would love to see a system like this that also acts as a charge controller, I think that might help justify a bit of that cost -- They're pricey little pieces!

[@RVwithTito]

Thanks so much. I see arguments both ways. Personally I prefer separate components instead of having the charge controller as part of the inverter. It limits the flexibility of your design.

[@TOTALLYRELAXED]

I’ve been watching solar installation videos ever since I retired from 38 years of trucking in 2015….while I’ve learned a lot in that time about solar installs I have to confess YOU just twisted my brain in half with ‘this’ video! Lol! It’s somewhat confusing to me but at the same time I find it very fascinating! Thanks for sharing! Happy New Year! ~Jim~

[@RVwithTito]

I totally understand Jim. The AC side of things is a bit more confusing than the solar and DC side of the system. I'll get to the solar setup soon, which will make more sense.

Tito, I love your videos. New RV'er here. I also have a Winnebago class a ('14 Vista 31ke) and a? running victron components (12/3000, cerbo gx, smart shunt and a 100/50 MPPT.). I just wanted to say I really appreciate all your videos, and I look forward to seeing the rest of this install. Even though I only have a 30amp set up, I feel this entire video is still very applicable. Cheers!

[@RVwithTito]

Glad you're enjoying them. Yes...similar setup. Since we don't really hook up we're rarely on 50A.

[@ScottFoxRVTravel]

Great description of how the pass-through split-phase inverter works. I have had trouble describing how this works on my RV. In order to run my air conditioners (one at a time) from my battery bank I also had to do a full rewire of the electrical distribution panel. Right now we are dry camping in an area that is still 75-80 degrees at night and we run the air conditioner from our battery bank all night recharging the battery bank from the solar and generator the next day. Sadly our 1800 watts of incorrectly angled solar panels can't keep up with our air conditioner use.

[@RVwithTito]

Hope you get it all sorted out. We're still in cooler temps so A/C is not really an issue yet.

[@johnnyallan3640]

I’ve been waiting for a detailed video on this. Thanks for sharing!

Very nice Brian can’t wait to see it finished ✅

[@RVwithTito]

Thanks. Stay tuned.

[@glennjames9152]

Can I use the multiplus 2 on 30a service and just use one leg? I am going to eventually going to upgrade to 50a but want to buy the Victron now; however, I dont want to spend the money on a multiplus then have to buy the Multiplus 2.

[@RVwithTito]

Sure can. I rarely plug in anymore and when I do it's usually only 15A. The Multiplus will split the output across both legs if you have them both wired up. If not then just wire up L1, neutral and the ground. 👍

[@KenLecomte]

You explained that so well. Thank you

[@RVwithTito]

Glad it was helpful!

[@goththicus]

Nice work, and nicely planned. I read the article about in RV Today. I can see why you like tinkering around your RV and making it more efficient and RV’ng off the grid.

[@RVwithTito]

Thanks! Yes. There's always something that could use some improvement. It's a great feeling when you finally get to use it and benefit from your hard work too :)

[@davidpatrick1813]

I am working on installing my Victron MP II 12V 3000VA but it is going into a fixed location, a radio shack for ham radio. I am having to think quite a bit and look forward to getting it going. Later I will put some solar... it is a much smaller capacity than yours... I am doing the 400Ah minimum that the V manual states and can grow it later. I am going to use it with 120 30 in and later when 50 amp service is available put both in.

[@RVwithTito]

Nice. Good luck with the upgrades!

[@robertnorvell1580]

Enjoy your channel immensely. Helped me with several projects. BUT I couldn’t find a video about insulating the underbelly of a Class C. We’ve done some winter camping in or minnie Winnie 25b. I have been considering installing foam board underneath it to help conserve heat and cool. For example the rear cargo holds are just plastic tubs exposed directly to elements and there are large areas that are bare subfloor exposed. All waterlines run inside so it would seem to be just a process of jenga with foam boards to create an additional barrier. I didn’t know if you have enclosed or insulated anything. I know you’ve done cold weather camping so I figured I’d ask?

[@RVwithTito]

Sorry no video on that topic. My subfloor has at least a couple of inches of insulation. There's no insulation below the compartments though.

[@philsmith5400]

REALLY enjoyed the video, Brian! I would LOVE IT if you would do a video on things to consider in buying an older RV - I want to consider doing the same, but I don't have an old friend with an old RV that I can trust!

[@1peachcowboy1]

Thanks so much! Built my confidence to do the project and your discount code was an added bonus.

[@ryanh4889]

Another great episode Tito! You did not mention that if you are just plugged into a 30A socket that the inverter can 'boost' the AC power to 50A to power the entire coach (water heater, dual roof ac, etc) using power from the battery bank which may also be supplied from solar panels. Victron equipment with the Cerbo, Touch 50, BVM712, is just so easy to work with and reasonably priced (compared to some of the Xantrex stuff which seems to be VERY expensive).

[@RVwithTito]

Sorry I didn't mention that, but YES it's a great feature of the Multiplus inverters. I've already used that feature.

[@DeekJohnson]

Yes that's what NOBODY is communicating...this is awesome. Can run 50a service plugged in or not. That's what I need

[@dan0gram]

Great video! Thanks.

[@campingforayearrenoheart5908]

Option 4 put a transfer switch and place a jumper wire from L[ - L2 ? Works great

[@MrSummitville]

Isn't that same effect as using the 30A male -to- 50A femaie Dog Bone? Why do you need a Transfer switch? Either way, you have the same problem when there is NO AC power input ... The Victron is running on the Battery Bank only, now how do you bridge the Victron L1 & L2 outputs? The Victron has OPENED both L1 & L2 inputs removing your bridge between L1 & L2.

[@rvgearguy294]

[@mikequinones2682]

Great Job so far Brian.. good explanation on the 50 amp service vrs. 30 amp.

[@cluuck4617]

Nice how they are a full 50 amp now with no need for a sub panel to power off the inverter.

[@RVwithTito]

Yes. It's fantastic 👍

[@barzalou]

Even if my class A RV runs on 30a, your approach and logic is very sound. I may have a few concerns of additional weight that will have to distributed evenly with the batteriea on both sides of the RV and how it influences your tire pressure levels but aside from that, it's very good.

[@RVwithTito]

Thanks for the feedback. I believe I'm balanced out pretty well. Plus I did remove two large lead acid batteries on that side.

[@2WheelWild]

I know this is an older thread, but did you disable the charge line from the converter so it’s not charging the batteries from the converter?

[@RVwithTito]

Yes. I removed the converter/charger completely.

[@jimmiller4951]

Good information Sir . I just purchased the exact components that you just installed but I do not understand why you ran your Shore and generator into the existing transfer switch because that inverter already has it's own built in transfer switch . Please explain and thank you.

[@RVwithTito]

The two transfer switches serve different purposes. The RV's Automatic Transfer Switch (ATS) switches between generator and shore power coming into the RV. The Inverter's transfer switch handles the switching between incoming AC power (from the ATS) and inverter power. That incoming power could be from shore power or from the generator (hence the other transfer switch).

[@KRich408]

Awesome Video!!! 👍👍 I've been holding off on a install in my Travel Trailer because I knew it was going to get to small for full time fast, I just traded it for a larger 5th wheel camper 👍 , the only thing I need to figure out is what to do with the 12v converter? Since it's needed to power everything 12v in the camper, the issue is it will also want to charge the batteries and it's not safe for the Lithium batteries. I'm not sure if I can just remove the circuit that's supposed to charge the coach batteries or I will need to replace it with a converter that's Lithium compatible? This technology is so far ahead of what the RV manufacturers are doing.

[@RVwithTito]

If you install the Multiplus II, then you can remove converter/charger. The MP II takes care of that function.

[@bparkinson1234]

Hey. Also the quirkie thing you may discover with the Cerberus is that you cannot trigger a relay with the temp sensor. Example. I have a fan that kicks on at 90. Had to do it with separate unit. This is a programming issue that victron has not done. Thanks again

[@RVwithTito]

Thanks Bill. I got a cheap Chinese switch to do the trick. Works like a champ.

[@bparkinson1234]

@@RVwithTito yep. Same here. Maybe victron will change the programming. Many applications for this.

[@DreweZanki]

One thing you missed mentioning - the Multiplus II can 'boost' power - so if you have 30 (or 15!)A, you set that as your input - and if you 'use' more, the inverter will use the batteries, up to a 20A boost, to make things work. Great for moochdocking off a 15A cable at someones house for example :D

[@RVwithTito]

Very true. Yes. That's a nice feature of the multiplus.

[@buckfrnka2774]

@@RVwithTito No sir, afraid not.

[@meandtee_travels]

I’m guessing here, but, the white hose coming down in front of your inverter would seem to be either the drain from your sink(?) to the grey tank or your fresh water fill line. I had one of those crack over time. That location would not be a good place for a leak. I hope you have inspected and or replaced that if its pretty old or potentially have a plan to keep your electrical equipment protected. Good video! Happy new year!

[@RVwithTito]

Yes. I'm keeping an eye on that. It's the gravity fill for the water tank an it's in good shape. No leaks currently. Also, nothing is sitting directly on the bottom of the compartment and all cables have drip lines. All that's missing is probably a drain hole.

[@brycemoulton5716]

Thanks for the video, great stuff. Question, I have the same inverter with a 30amp shore input. Would you see a need to breaker or fuse that input before the inverter in case the inverter tries to pull 50amp?

[@amsoiladam]

Do you have a link for this for a 24 volt system?

[@Schwartzworld]

Another great video and install. As usual, a couple of things for you. The 6 gauge wire you use for the AC panel is too small for the 50 AMP load. It appears the wire you pulled out is bigger. I used 4 gauge wire to wire my AC panel. If the transfer switch is original, replace it. I don't like automatic transfer switches anyway but they are a necessary evil. Check all the contacts inside yours, they may have burn marks on them. They can be cleaned up but I'd rather replace them. Better safe than sorry.

[@RVwithTito]

Thanks for the suggestions. The original wiring was also #6 so I kept it the same. Good note on the ATS. I also replaced mine when I found some burnt contacts. All good now.

[@ChuckCassadyYT]

It all depends on the ampacity of the wire used. Romex #6 can absolutely handle 50a. 8awg Ancor marine wire can handle 50a. I suggest you look up the ampacity table of your conductors before you make these kinds of comments

Great Job Bryan! Can't wait to see it up and running off Grid! Keep up the great work! 👍

[@RVwithTito]

Thanks!

[@deanwebb1299]

Dude great job! Looks very professional. Well explained I understand all of the functions i would need now! My only question is do you have to do anything special when you connect shore power? Or does it auto register that you added input?

[@RVwithTito]

It's automatic. Once the inverter detects split phased shore power, it automatically switches to AC pass through mode. The system is very programmable and there are a few related settings that will determine how that is done.

[@tannerjim]

Was it easier to take all wires from distribution panel, back to MultPlus vs taking output from your TS and connecting that to output of Multiplus. Then, you'd only have to wire from the output of TS to input on Multiplus. I did mine this way, but 3 years ago with a GoPower IC2000. Keep up the GREAT work. Maybe someday we'll bump into each other here in the PNW.

[@RVwithTito]

Depends where you mount the inverter. Mine was very close to the distribution panel with the ATS on the other end of the rig. If the inverter were closer to the ATS then your suggestion would be the way to go. Take it easy!

[@davidbaize8359]

You do a great job here i thank you . curious i also have a scimarine system in place and want the mutiplus . Question did you keep the scimarine and did it connect with victron well.

[@RVwithTito]

No the Simarine PICO is in a different rig. I decided to go all Victron this time and monitor remotely.

[@gobfranklin6759]

Love your approach. Would a multiplus eliminate the need for my rvs transferr switch and the converter boxes!? Would be nice to wite everything into the multi box. Fyi, i still have a generator in the rv, besides shore power inputs for ac.

[@RVwithTito]

You still need a transfer switch to switch between generator/shore power. The converter/charger is no longer needed.

Hey Bryan I watched your video again this morning. I am impressed with your shop. I'm really interested in how you went ahead and benched test, configured, your inverter before install. I also have the MK3-USB and assumed ---- that with proper isolation of components I could wait until installation of the inverter and then the Cerbo GX /Touch 50 on account of the Lynx system. I was thinking as long as I had a long enough cable and a comfortable spot again I assumed----- Just thinking

You could certainly set it all up during install. It was pretty cold and rainy outside. So hooking it all up and testing it in the shop was better for me. Plus I could workout any issues ahead of time. Good luck!

[@skiimountaineer]

Nice job Bryan, I am installing the same exact thing! I just need to get two more batteries, at least the price came down… in my opinion this is one of the best systems on the market.

[@RVwithTito]

Agreed. Eliminates a lot of work arounds.

[@animallovefest143]

What batteries are you using? I contacted Renogy recently and was told all lithium phosphate batteries should be purchased within 6 months of each other, so they age at the same rate, and you're not adding a new battery to used batteries. Are you aware of this? I have two Renogy 170 ah, and wanted to add another, but they are super expensive, and actually went up by over $100 in the last few months $1,600 - 1,700.

[@RVwithTito]

@@animallovefest143 I have 3 Battleborn GC3 batteries. Checkout my previous video to see how I hooked them up. I don't think that's a hard rule, especially with LiFePO4 batteries that have a very long lifespan. But if it's what they say, then that's it. It's certainly an important guideline with lead acid batteries.

[@trevortrevortsr2]

The Growatt does this and can be purchased without the need for a split phase to get 240v

[@RVwithTito]

Good to know. Thanks.

[@jodydewey]

I love watching your videos. I would love to chat with you if possible. I have some questions since your rig has basically the same chassis as mine (workhorse W22). My electrical panel is in the rear of the coach, basically directly above the transfer switch. My plan is to mount the Multiplus II on the roof of the bay and route my cables straight up to the panel.

[@elderschneider2131]

The best video... 👌

[@RVwithTito]

Thank you so much 😀

[@stevekrud2715]

My question is normally you would have two AC panels one being powered by inverter either in pass through or when inverter is turned on. It looks like the open hole above the panel you wired into may have been that panel. How are you powering all those circuits that the old inverter powered.

[@RVwithTito]

These large hybrid inverters are designed to be full house inverters managing and switching between shore, generator and battery power sources. It's what we prefer since we RV solely off-grid and don't plug in. Some might consider this type of configuration a bad thing...a single point of failure. Do you lose power to the entire RV if your inverter fails? Actually, yes. That's something to consider. It's why we chose to spend more money on a high quality unit like this Victron Multiplus II. It's well tested and very robust. Not to say that this too won't fail. It just hasn't. We've been running it 24/7 for the last year without a hick-up. So far so good. I used to carry a spare pure sine inverter...just in case. But I no longer do. What you are describing is how it used to be when inverters were smaller and didn't have hybrid functionality. Of course you could still setup your system that way with dedicated inverter circuits. The 200W inverter I ripped out of the 03 Winnebago only powered the TV and an AC plug in the cabinet. I rewired that plug to tie into the main AC service. Hope that helps.

@stevekrud2715 The MutltiPlus-II *2x120* ( in ths video ) is rated at 3,000VA. Which is only 2,400 Watts continuously. It will *not* run everything in a 50 Amp RV. Probably not even 50%.

[@christopherrasmussen8718]

Here is my 'million dollar' question. I have a Victron Quattro 5KVA (5000 watts) inverter in my coach. I have it wired basically like this. My thought is why even have the transfer switch in the equation. The inviter will switch something like 120 amps between the generator, shore power and batteries. It can shift in a fraction of a section and start and sop the generator.

[@MrSummitville]

@christopherrasmussen8718 - Do you have a 50 Amp 240 Volt RV?

[@christopherrasmussen8718]

@@MrSummitville well it’s a 50 amp coach with parallel lines in the coach. 4 wired + ground vs what a household dryer that is 240 between 3 wires and ground.

[@winginitwithjohn8451]

Great install video again, thanks Brian. Now if I could trade in my 1.5yo Victron 3000 inv on this new 3000 ll, life would be better.

[@RVwithTito]

That would be cool. You could probably find someone to buy it.

[@denisestarr2314]

Ok , offgrid cabin . Solar 30amp 30amp sinle pole breaker hooked to side B Genorator 40amp 240v . Wired int a home breaker box , Genorator hooked to main breaker suppling power to A n B sides . So this enverter would allow me to take battery power and Genorator power IN , and send double phase power to main breaker . Supply power to A n B . And the enverter would do the automatically switch . Fallow , then I would be able to balance the load , and could use 240 for my well pump .?

[@brucemontgomery8136]

great explanation- sounds like the inverter has brain to do what a person had to manually do before. have a great 2022- healthy mostly and happy usually 😜

[@RVwithTito]

Thanks! This inverter is definitely a few steps up from what I was using.

[@davidpatrick1813]

Looking good. I like the blue wire cover ... My system is much smaller ... and using a victron solar and dc to dc ... but not hooked up. I'm using a measly 200 amps... which is okay for my mini motorhome.. just trying to decide if and when to use an inverter.

[@RVwithTito]

Yeah. I thought he blue tubing would be a nice touch. Good luck with your upgrades.

[@CurtisDrew1]

Some Great Content Brian. I'm doing some upgrades (cough) to my 89 Fleetwood Limited and I have an Off Grid Solar System install in the planning stages. I think you have some good advice that I will be using on it in in a few months. Currently finishing up my repower from Gasoline to Diesel. Gonna be a Hoss! Finished up the hydraulic parking brake system yesterday. Engine and transmission are in. COnverted the shifting over to push pull cable, it's a FERD chassis. Solar System will get set up and mocked up before I reroof it and wrap the the old girl! I've been kicking around the idea of swapping out the roof top Coleman AC Units and going to a dual cassette mini split for cooling. I think this Victron Multiplus II Inverter will be just the ticket to make all that work. Yea, hoping to get enough solar on the roof to run the Mini split with cassettes in place of the Colemans. Lucky for me my Coaches Electrical system is all on the drivers side and plummed in easy access! Rock On Dude!

[@JRathor]

Hello Brian Happy New year to you and the family. Hope for the best in new year. Excellent and detailed explanation. I really enjoyed it. Just let you know that I bought the Multiplus II just like yours last September for my 2007 Fleetwood Discovery 39V. But did not have enough time to install yet. I have to wait till May or June when weather is good. Around my farm in Alberta last night the temperature was -40C. I will be waiting for your video of progress. I think that your electrical system and my class A system are very similar. I learned quite a bit from your video. Good luck.

[@RVwithTito]

Yikes! That's cold. Definitely wait to install it. Glad you enjoyed the video.

[@scottasire5740]

My wife and I, really enjoy your videos, we just bought a 2004 class a and are doing a pretty major renovation. Anxious to see what you do to yours. Really anxious to install solar panels and do some boondocking.
