Charge Your RV WITHOUT Solar or a Generator // Alternator Charging // Off-Grid Power

How To Get Power in your RV without SOLAR! Charge from your alternator!
We discuss the steps needed to set up and install an alternator charging system (DC-DC Charger) in your RV. We have dual alternators and installed dual Renogy DC-DC Alternator Chargers in our NuCamp Cirrus Truck Camper. We share the process we went through and how it works. This system allows us to charge our 600AH Lithium Iron Phosphate (LiFePO4) Battery Bank at 40-80 amps while the truck is running. Since we drive a lot while we travel, this is now our main source of power.
At this point, we will probably get rid of our generator and add a few solar panels for the few times that we stay still for more than a few days at a time.

[@ZiggZagg11]

It reminds me of the, "One thing doesn't belong here"... I know you know,... and realize you are limited in your utility space... I am referring to the water lines and water pump in the same space as all that electronics... :)

[@Stonyboot]

100% agree. The real story was that moving the pump wasn't part of the plan. It was originally separated from the electrical side. I had a hard time limit on the project and I had to just get it done. I have since fixed the problem and will have an update video out in the future.

[@gardnergerry1182]

Scott, don’t replace the copper lugs, just spray some Fluid Film on them and don’t worry about corrosion. $15 at Lowe’s.

[@Stonyboot]

That’s a great idea! I was thinking about liquid electrical tape, but Fluid Film is pretty useful too 😊

[@kraisydave]

Exactly the video I've been needing! Thank you so much for taking the effort and sharing all those details. 2014 Livin Lite 6.8 truck camper

[@Stonyboot]

Water near the electrical equipment!!! I wanted to explain the water pump situation. This project had a hard time limit and I had to make compromises. Since this video, I fixed the issue with having the water pump in the same compartment. I haven’t made an update video yet. I have made some other changes that I’ll cover in the future. It wasn’t ideal, but there was no other place to move the pump. If for some reason the pump were to let go, the electronics are now protected. I’ll explain in a future video. Thanks for all the comments!!! Also, I forgot to fully explain why I installed dual chargers! Due to cable size requirements and amperage limitations on exterior plugs, I could only find parts to wire up a 40 amp charger. I need more than power than a single charger can provide, so running them in parallel gives me more amperage without having to go to 0 or 00 gauge cable. Another “feature” is that I can charge at either 40 or 80 amps and it provides redundancy in the event one fails (power is pretty critical for us). I only run both chargers if I need to charge quickly. If I’ll be driving for many hours, I can just leave one running and reduce the load and heat generated by the alternators and in the chargers in the battery compartment.

[@normnilsson7208]

Makes sense, thats a great set up, can yout batts handle that amount of current showed down its throat ? how hot do they get at 80 amps ?

[@mee9006]

I don't believe it would have occurred to me to use 2 chargers. Good idea. Good video. BTW, I have that same truck. Good luck guys!

[@Stonyboot]

I found that you can have as many chargers as you want, as long as they are setup correctly. I might add a 3rd in the future. What do you think of your truck? We have had some small issues, like door gaskets and our power steering system is failing.

[@mee9006]

@@Stonyboot I've had some trouble with mine. It's a 2015 so got it when RAM/Cummins were still trying to figure out the exhaust system so had exhaust worked on after "check engine" light. Warranty job so... It did leave us on the side of the road twice. Water pump once and transmission cooler line ruptured the other time. You get time, check out those metal lines going to your cooler. Another guy I know had same thing happen to him. They rub on something. I still haven't figured out where. Should have asked when mine was worked on but we were a couple hundred miles from home and in a rush to get going again. Both breakdowns were pulling travel trailer which made them really fun. I have the 68RFE transmission and it had to be rebuilt at about 95k so spent a few days in shop for another warranty job. That's been over 2 years ago now and since then all good so hopefully all bugs worked out now. My wife still says it has to go.

[@Stonyboot]

That’s disappointing to hear. I’ll check the lines and keep an eye on them. I have the same transmission which I have read both good and bad things about. I’m hoping I got a good one! Thanks for the info!

[@bob_frazier]

Thanks for convincing me that this is more complicated than I want to ever tackle!

[@SkypowerwithKarl]

The one thing I’ve learned over the years is, it’s not a matter of if a RV water pump leaks but when. So much so that I built a catch pan under it with a cheap 9v battery powered moisture alarm. The proximity of all that $$$$ electrical makes me uneasy. Also all that heat generating equipment in such a confined space may be a concern, perhaps more so further south in warmer climates. I’d be considering some ventilation, perhaps a thermostatically controlled fan into the interior. Two small louvered openings(one with a small fan) at opposite end of your battery/electric compartments. Keeping the vents small will help keep the fan noises contained. Other than that you have caught all the electrical nuances for your lithium system.

[@Stonyboot]

Excellent points! I never mentioned it in the video, but that was a temporary solution due to time constraints and a lack of parts. That water/electric issue has been solved, I just haven't made an update video yet. I was also concerned with the heat generation issue, but after many hours of testing, it stays quite cool in there. For reasons that would be hard to explain in a comment, that compartment is large and well ventilated. I have made some changes and will be doing an update video in the future and I'll be sure to explain how the air flow works. One aspect I haven't been able to test is when the weather hits 90-100f. In that case, I might use a small fan to supplement air flow. I have a couple other projects to finish and then I'll get back to work on the charging system. Stay tuned :)

[@qpoole90]

Really enjoyed the thoroughness and detail of this video.. I just installed a dc-dc charger in my truck camper (before seeing this video) and to avoid the 3 prong connector, I used a Anderson connector and I ran the ignition sensing wire to my tail light wire (night lights) on the truck camper. So if I want the dc-dc turned on, I just turn on the truck lights and it sends the power to the ignition wire and turns on the connector. That way I can turn it off if I am stuck in traffic or idling for a long period.

[@Stonyboot]

Thank you! I considered doing the same thing with the tail lights, however, I didn't like the fact that I couldn't control each charger independently and that I wouldn't be able to turn them off at night. Later, I found out about wireless 12v switches that would have been perfect, but it's built and working well, I might as well stick with it :) Thanks for the comment!

[@wolfgangmozartSM2032]

Wow, Scott -- You're a frk'n genius. I've long thought that I could use the alternator of a motor to power up electrical systems in my day-dreaming of living on the road, but I had no idea of how to do that, but now, thanks to you, Scott, I have a clear pathway of creating that! But, first, I gotta buy a truck and a camper shell before setting up anything -- no cart before a horse, right? *grin* It won't be until early in 2022 before I could start to make my moves in the direction of RV-ing.

[@Stonyboot]

It’s been working really well. At some point I’ll make another video about my power system.

[@senseidadproductions]

thanks for the details and thorough explanations! I really appreciated the way you walked through it all. I'm happy to say, I have done a similar build using my Tacoma and a GoFast Camper. I have an AGM battery as the house with a RedARC DC-TO-DC charger and I ran the heavy copper wire to the the bed. It works really well and I did not have issues with the alternator. I have been using this for a while and now I also supplemented with a 700 watt Bluetti Solar power station that uses a a mix of solar, AC and DC to recharge. If I had to do it all over again, I would probably get the lager 2000 or 3000 watt Bluetti - it's just so much simpler - especially since I have heavy gauge copper running to the back to make it easier to charge. Thanks again for the video!

This was your answer to being able to go up to 440 amps continuous and not needing to use a 70 amp plug. Im using these thru the inside of the bed of my 01 Dodge ram. There are tons of options without having to use two chargers.

[@Stonyboot]

Dual chargers was a design decision. It allows some flexibility that a single larger unit does not. It lets me run at either 40 or 80 amps of current and it provides redundancy in case of a failure. After researching 60-120 amp chargers, I decided to go with 2 smaller chargers with the option for a 3rd in the future if we need it. Our alternator has a theoretical max of 440amps of output, but they would burn up really fast. At max load, we only pull about 1/4 of the max and that is well within the safe limits for continuous operation. Many thousands of miles of charging with no problems yet. I am going to swap out the breakers for fuses now that the weather is warming up. They tend to trip when the sun gets hot.

[@ThePracticalProgressive]

Great, detailed video, thanks from a nerd who’s always looking for more information 🙂. Especially useful was the comparison between connectors, was thinking I’d need Anderson connectors which handle the amps, but was worried about fishing that wire size. 👍🏻

That’s funny I have the same trolling motor plug and works great and I like how you used the extra post for your signal wire and I have a flush mounted switch that lights up when charger is on. I did this to let my truck charge up and then flip switch to tur charger on or off .

[@thesurvivalist.]

You’re a brave soul to put a water pump near an inverter! Nice upgrades regardless! Amorphous solar and Polycrystalline solar, are options for low light regions no like Alaska or wooded areas!

[@Stonyboot]

That was a temporary solution. I was short on time, patience, materials and tools. The pump situation has been solved, I just haven't gotten around to making an update video. I'll get it done soon! Thanks for the tips on the solar. Upgrading solar is on the agenda for when we are stationary for more than 3-4 days. Mono/poly/amorphous all have tradeoffs. I haven't finished researching and deciding the final design, Poly might be the winner though. I'll get a video out when that project gets underway.

Luckily, with a 34 foot Class A, I don't have the space limitations you have... so I went an even bigger triple supply route. I usually stay the limit when boondocking, so there's 2385 watts (9x265 wired three sets of three in series) of solar on the roof and no AC units to get in the way of the layout (went with mini-split heat pumps, 12,000 BTU in the front and 9,000 in the bedroom. Both running full blast use 70% of just one RV type AC unit!). In addition, there is a 3100 watt Champion inverter generator that, if needed, can supply the power to run the motorhome while still providing some charging to the batteries (I gutted an old roll around 60 amp battery charger). I also installed an additional 135 amp alternator dedicated to charging the house batteries while driving, even though I usually limit myself to 150 miles or less a day. With warm-up and miles and cool down the engine is still running around 4-5 hours. Why waste it, right?! I wish I could downsize, since it's only me, but my requirements prohibit that. I HAVE to have a bathtub (with 110 degree water) to soak the pain away every night to be able to sleep, and in the morning to be able to hike . There are two additional 38 gal water tanks in the pass-thru of the basement. Through several electric solenoid valves, and an additional water pump and heater to keep the soak system totally separate, I draw water from one tank, and drain into the other tank. Then through more solenoid valves, I pump the water back into the supply tank for the next time. I don't wash, just soak, when using the system... so a cap full of bleach keeps the water fresh for 2 - 2 1/2 weeks. Hey... we do what we have to if we want to be out there enjoying ourselves, right???

[@Stonyboot]

THAT is an awesome setup! Where are you located, I would love to check it out someday! Space is our biggest limitation, we can get about 600 watts of solar on the roof, which we will do in the future, but that wasn't enough to keep up with our needs, especially if we got a cloudy day or a shady camp spot. Running our computers and electronics is our lifeline. Redundant power is essential for us. Sounds like you have a great setup. Do you have any pictures or videos you can share with us on Facebook or email?

[@donf3877]

@@Stonyboot The panels I have are commercial units (a lot beefier construction) bought used, so they are as browned over as they will get. If you can, try to get the same size and manufacture when you buy your panels. It's much easier to wire them to your advantage. Mine are mounted three on each side up front long ways with 14" between them for cleaning, and three behind the bathroom skylight sideways over the bedroom. Wired three sets of three in series really helps, since they are fixed mount. Less than a half hour after sunup the charge controllers are already switching on, and I get up to 120 volts from each set mid-day. Gotta love those MPPT controllers! I actually built an aluminum catwalk between the panels up front after I realized they were shading the roof and cutting down on heat gain from the sun!!! I'm stuck down in Florida for the time. Had lung cancer surgery at the VA, half the right side, but they couldn't get it all (too close to the throat). Went through 6 1/2 weeks of daily radiation treatments. I'm halfway through a four dose one every three weeks chemo treatment now. Once that's over with... got a little work to do on the old girl. She ate the cam (chevy 454's are known for that). Installing a RV roller cam and roller rockers for more power and less wear. Then a low rise aluminum intake and Holley fuel injection. Redoing the exhaust, too. Headers and dual 3" exhaust with straight through semi mufflers. That will probably take me through the end of summer. Just in time to head across the bottom on I-10 and get out west again. I subscribed to your channel, so maybe we can hook up in the fall!!! I don't do much with pictures and videos of my equipment... like to leave no footprints. But, I might video the engine work... who knows.

[@donf3877]

@@Stonyboot Just thought... If you get smaller panels, cover the roof. Then, you might make a rack that could hold more panels that would be attached to the side of the camper while traveling, but could free stand on the ground once you're stopped. You could almost double the amount of panels!!!

Awesome Sasha and Scott. Good tip on the trolling motor connector! No issues with it wriggling loose? I was bit nerve racked about cutting into my TC wall but now I am confident. I also bought breakers but read somewhere about high heat environment tripping them so I changed directions and am planning on a fuse in the engine bay. Breakers by the charger in the rig. Great job on the video and project.

[@Stonyboot]

100% agree. The breakers have tripped on me due to engine/ambient heat. I’ll be putting them inside the camper and using terminal fuses in the engine bay. I don’t like making holes in the camper either, but that was a nice protected place with a plug designed for the task. Time will tell, but so far, so good 😊

Great video, guys. I'm curious if your foam mounting plate is held in place with a combination of friction and the cables hanging down around it or if you used another method.

[@ssyoumans]

Excellent video. What was your input amperage for one dc-dc charger (50 amps)? I like the Victron dc-dc with auto-sense, but they are $$ and only do 30 amps. I too am leaning towards the Renogy.

[@Stonyboot]

The charger pulls about 50 amps from the truck and outputs a steady 40 amps. It's been working great!

[@yourmamalikesmacncheese]

Great video. Convinced me to pass on the project.

[@Stonyboot]

While I do love the power, the project was a little difficult, mostly due to lack of space.

[@PolymathX]

Amazing research and effort. Did the dc-to-dc charger have a controller and display screen? How do you track battery capacity/current charge?

[@Stonyboot]

Thanks for watching! The chargers have no display or external monitor, they are just an on or off system. To monitor everything, I use a Coulomb meter battery monitor as well as a Bluetooth app that connects to each of my batteries independently. These monitors give me amps, volts, watts, AH remaining, and run times. It's a basic setup, but provides all the info I have needed so far. I've been charging a lot lately and it's been working great!

[@allanmain5666]

This is very helpful. Thanks for doing all the figuring for us lol We bought the new 920 and put it on an F350 dually, also new. There may be times when having the 930 watts of solar may not be enough, like when we are in the northwest, so this will help us a great deal. Our truck comes with a 250 amp alternator, so I may go with the 60 amp charger. I'm thinking that I may also have the ability to wire it into the upfitter switches. Fun stuff, but still requires some planning. Your video will help a lot. I hope you get something from the affiliate links.

Thanks fir watching. That’s a great point, and to clarify, we never idle it to charge. It’s only while driving. The most idling we do is while driving in traffic. The hour idle test that I mentioned in the video was simply for testing heat buildup while not moving. Luckily, the alternators never got too hot!

[@standingmannequin7911]

Hi Guys, I appreciate you taking us through this. I realized today from your video that I really need to protect my cables much more. I have most of the components and I'm anxious to get this going. I figured out a route for the cables on my Ram 3500 including the cables to my auxillary switches but that may change. It's a good thing I stopped installing when I did. Something about the cables being too exposed to danger. After watching you I'm looking to go the PVC route. Maybe you have some more pointers regarding your cabling route after the PVC and up through the fender even to avoid the engine compartment. I appreciate your quality work and want to do this right.. At the 11:46 mark I noticed something I want to ask you about. The PVC fasteners. I hope you decided to go with a something stronger to fasten the PCV up there than what looks like a small zip tie. I bet this was just to hold it there while you figured out and made a bracket of some kind... I wonder where you decided to screw into. I think you pieced together your footage wih your demonstration super well done. I'm learning that this is not something to be rushed especially if your not sure on something or it's your first time installing something like this. Thanks for sharing you insights and lifestyle with us all.

[@Stonyboot]

There is a lot to learn about the electrical side of things. I'm always learning and always making mistakes. My videos aren't really a "how to" guide from a professional perspective, but a "How i did it" perceptive. I spend a lot of time reading, watching YT videos, talking to friends, etc. I assemble the project in my head, then on paper, then order the parts that I think will work. Then, I realize all of the faults, and adjust accordingly. Circuit protection is definitely your first step with any electrical system. Fuses and breakers are very important! And for the cables under the truck, I just wanted to prevent the cables from getting hooked on anything or chafing. I did use medium zip ties, 2 separate zip-ties at each area that I could access. Later, I found my aluminum baling wire and used that to wrap/secure the PVC to the truck. I hesitate to drill holes as it promotes corrosion. Also, 98% of the stuff I install is installed in a way that makes it removable later without leaving any damage. So, I tend to use methods like this to prevent making permanent marks/holes/damage. That pipe has been under there for about 30k miles without any problems.

How the the charging effect your gas mileage? Would the current decrease automatically when the batteries are charged? What is the size of your dc to ac pure sine wave converter to your appliances? Great video, thanks.

[@Stonyboot]

Great questions! I have not seen a noticible impact in my MPG, It obviously uses more fuel, but I don't have an accurate way to measure it. I don't charge all the time, so it averages out to less than 1 mpg, much less from what I can tell. Two things happen. First, Lithium likes a constant current, constant voltage charge profile. As the internal resistance increases, amperage decreases, but only at the last 5-10% of capacity. Second thing is handled by the BMS. In my case, I have the BMS set to disconnect charging at a cell voltage of 3.55v instead of the maximum 3.65v. This gives me a buffer on the fully charge side which helps prolong cell life. Once any cell reaches 3.55v the BMS will disconnect the charger. That means the battery pack will charge to around 14.2v and then disconnects. It will quickly settle down to about 13.5-13.6. On the other end, I have about a 5-10% buffer on the discharge side to also help prolong cell life. A good BMS really helps protect the battery from over-voltage, under-voltage, over-current, high and low temperatures and insures that nothing goes wrong. I have a 2000 watt primary inverter/charger to run our appliances and big items. I also have a dedicated 1000w inveter that just runs our computer/electronics, that smaller inverter only handles 200-300 watts with our computers, so the cooling fan never even kicks in :) Let me know if you have any other questions!

I did look at their DCC50S. I ruled it out due to a lack of Bluetooth connectivity and the 25 volt solar limit. I want to keep my DC-DC Charging system separate from my Solar setup. However, I think its a great idea, I just didn't fit my specific needs. Are you using it? What do you think?

[@ssyoumans]

Look forward to the battery build video. I too plan to build my own using 280ah LiFePO4 raw cells and 200 amp BMS. Probably put 2 in parallel for 540ah and 400 amps (only need 250 amps max for my 3000w inverter, but don’t want to drive the BMSs to hard). There is a serious lack of quality BMS with temp sensors.

[@Stonyboot]

Which BMS are you going to use? I'll have a video out about that in the future, still in development.

[@ssyoumans]

@@Stonyboot That is what I was hoping to hear from you. Overkill Solar makes a great BMS with low temperature cut off but only 120 amps. A DALY one would probably be ok if batteries are in heated compartment that will ensure they don’t get below 32 degrees while charging. If I go with DALY, probably the 200 amp model. Eventually (2) 280 ah batteries in parallel for 560 ah and up to 400 amps (but wouldn’t need more than 240 amps to drive a 3000 watt inverter). The oversized inverter would run cooler.

[@Stonyboot]

I'm running a JBD that's also good for 120 amps. I only need to run a 2k inverter and never get close the 240 amp max. My biggest need is run time for the computers, so big battery with a medium BMS. If I wanted to max things out, I could simply install a contractor/relay, but they complicated things and reduce reliability. Finding a good BMS with low temp protection has proven hard, especially anything over 200 amps and with Bluetooth management. DALY has some great options, but I really love the JBD.

I'm pretty sure a 2002 won't have a smart alternator. (sweet truck by the way, I love those 7.3's!) As for the switch in the middle, absolutely!

[@charlest7027]

Found your video by chance. Do you have a shunt to monitor the amps coming in? For example a 130amp alternator will get burnt out quickly consuming 80-120 amps when only 50 amps coming into the battery bank so one would have a deficit. So the plan is to install a 300amp alternator and dual 50amp DC2DC charger with lithium profiles to get roughly 92amps due to loss in efficiency and then the other 40 to 50 amps from solar on a sunny optimum day. to get a surplus or net out when consuming 120amps. So it be cool to see your data and numbers in real world applications.

[@thelongroadhome7582]

Scott Thanks for the awesome info. I might have missed it, but did you do anything to the Cirrus convertor once you replaced batteries with Lithium? The converter takes shore power and charges house batteries while powering the 115VAC. So would it need disconnecting or its charge profile changed? Or maybe you never use shore power?!

[@Stonyboot]

That's an excellent point, I never mentioned it in the video. I removed the converter and went with a Xantrex Inverter/Charger. It has custom profile settings to accommodate Lithium chemistries. When we connect to shore power, the inverter/charger takes care of charging things back up.

It is an option. A similar investment in Solar might also do the trick. Solar for us is on hold until I know the specifics for the Starlink mobile antenna. Then I'll add whatever solar I can around the antenna. I like the reliability of the DC-DC charging system, and it works for us since we drive a lot. It boils down to your own needs and how you plan to camp. The only time we use the generator is on really long hot days. It's too hard to work inside when its 90, so we run the AC off the generator when its needed.

I understand that its a tight fit for everything. Have you had any issues with the inverter getting hot? I have mine in an area under the bed, which is much more open than yours, so if you don't have issues, mine should be fine.

[@Stonyboot]

The only time I have had heat issues is when I use the inverter/charger to charge at 55 amps continuously. Keep in mind, it never shut down due to heat, it just feels hot to me. After 2-3 hours, the compartment gets pretty warm. Running the inverter to provide 120 volt power seldom creates enough heat to be concerning. If I have enough time, I'll run the charger at 35 amps which keeps it much cooler. I have my eye on some thermostatic switches to run a small 12v fan to move some additional air around when things get hot.

[@cirrus820travelers9]

Nice information! Crimping those large lugs it's easier to use a small table vise. More controlled than smashing with hammer. We have a 2019 cirrus. Switching 12v marine batt to 2 100ah Battle Born. Wondered how to charge. We prefer to store gen locked down on rear bumper and remove when operating 30' away.

[@Stonyboot]

I don’t have a vise any more, we sold everything and live in the rig full time. So, sometimes I have to make compromises. A hydraulic crimper would be ideal, but takes up a lot of space. For charging, I guess it depends on your usage. We cycle our batteries every 2 days, so we needed a lot of power to fill them back up. Even at 80 amps, it takes a long time to charge 500-600 ah. I do the same, put the generator far away from the camper to keep things quiet! Do you have a 820 or 920?
