Heaven sent! I wish I watched this before I wasted the weekend watching do-it-yourselfers and still not getting it. This was professional and fully comprehensive. Thank you
Wow after 10 years dealing with my Boat batteries I finally found someone that puts everything into a simple and easy-to-understand video. Thank you.
You are welcome Vito, I am glad to hear you appreciated the video. Sorry I didn't upload it ten years ago :)
This guy knows his stuff. The information was crystal clear and easy to follow.
That is nice to hear, thank you for your message!
The number of people who understand the rules, but cannot articulate the reasons is huge. This is one of the best videos I’ve seen on the topic.
I am glad to hear you enjoyed the video B Rad, and thanks for the compliment, I appreciate it. All the best, Jesse.
ive done a lot of homework with solar but what you did with this and other videos is just that little bit that helpes me understand exactly how to and what. thank you very much
Excellent video! This guy knows what he is talking about. And no annoying background music, marketing or horseplay! Great Job!
I've been looking for a very simple yet informative explanation like this for my whole entire DIY life. Thank you very very much, you just saved me from wasting time and money trying to find a solution for my current DIY project
Such a great message to receive! I am glad to hear the video was helpful for you. A great name you have by the way. South-Eastern Africa? Malawi/Zambia? All the best, Jesse.
I really want to thank you young man. You are a very smart person with a lot of common sense. This was very simple to understand and grasp.
Thank you for your heartwarming compliment Christopher, I am glad to hear you found the video useful.
All the best, Jesse.
Thorough, excellent and clear and to the point! Answered my questions to set up my boat systems with a new mechman high output alternator and clarified the options beautifully. You give us the information to make our own choices given our personal resources and goals, thanks so much.
Thank you for your message Doug, it is really great to hear how the video created this value for you. Good luck with your new setup!
I have had the pleasure of watching two of your tutorials and the clarity with which you deliver them is remarkable. I'm lost for words....Thank you.
Great to hear!
I watched this two years ago and knew this was solid information. Most of it however; went over my head. Here I am two years later, and through my own trials and tribulations can fully attest, this is good solid info.
System one was what I first went with with two AGM deep cycle. They only lasted less than a year. Went with option number 2 a year ago and I’m very pleased to date🤗😎🇺🇸
That is great to hear Earle!
Thank you!!! Good videos, I have seen a few of your videos and they are far better than most not only because of the information but the way you share it! As far as I'm concerned an instructional video is NOT a music video, so I appreciate the fact that no music is included, and we can clearly hear what you're saying, just like in a classroom, thanks! :) If teaching was more effective with music, classrooms would blare loud music while the teacher is speaking... ;) Keep up with the great instructional videos, the information is what's important! :)
Thank you for your compliment Michel, I really appreciate it. I had to smile when I read what you said about music & instructional videos, I totally agree!
You go into more details than others and it makes things easier to understand. Like the thin layering of the starter battery, for instance.
That is very useful feedback Eddy, thanks for your message!
Thank you so much, you’re the first person who has explained this properly
Thanks Peter, that is a great compliment to receive. I am glad it was useful for you.
All the best, Jesse.
@@SolarSolution Hey Jesse,
Which external regulator do you recommend for your system #3?
Top explanation of the different charging needs of a starter FLA and a deep cycle FLA! Thank you!
Thanks for your message Beni, I'm glad you are enjoying the videos. Jesse.
Absolutely wonderful video........excellent clarity on the points, one of THE BEST......THANK YOU for your time and efforts in sharing your knowledge. I have been watching hundreds of videos to get a grasp on this subject to properly understand the basic principles, finally found the right one.
Glad it was helpful!
I worked that out 20 years ago. External regulator is the only way to go. Huge battery life for both batteries.
Hi Ian, thanks for your feedback. I am glad to hear it worked out well for you. All the best, Jesse.
Very helpful technical info, earlier, I couldn't understand completely about difference between Car and home battery even after watching many other videos. Thanks helped me a lot.
Glad it was helpful Rohitha!
Thanks for a systemic and clear explanation! In my RV, I have chosen the simplest (KISS :)) parallel method with a simple dedicated high-amp manual switch. The parallel method seemed best for me because I have a solar charging system for my house battery as a main system and the alternator is only used when there is not possible to use solar. Stay safe everybody! Linas
Simple & effective, well done!
Thanks for raising my antenna's, discovering in conjunction w/solar, this configuration is most definitely feasible when weather doesn't permit for solar keep up! THANKS to both of you guys!!!
@@SolarSolution can we direct the plus wire of alternator by using a switch to charge each battery at a time...i mean first engine battery then house battery...one at a time
Thanks for the info! The visuals help a lot!
Being that I'm using my van for camping and not living in it, I believe I'm just going to use a Victron 9 amp DC to DC converter for my single AGM battery I bought at Walmart, and 100 watts of solar. I had looked at a solenoid to charge with, but I'm glad I decided not to go that route. I don't think I need a huge amount of power. That can always be upgraded later. It's in a 1998 E-150 van, and all running inside the cab to behind the driver's seat.
Hi Ben, thanks for your message. I am glad to hear you liked the format of the video! Thanks for sharing your experience with the setup for your van, I am sure this can be valuable feedback for other campers as well. All the best, Jesse.
I have my start battery/alternator connected to my house battery through an old solar charger, which is enabled with a relay from the car key, this was the most reliable/cheaper solution I found.
great tutorial well done
FINALLY good rock solid info
Hi Christian, thanks for your message. It is good to hear you found the video useful. All the best, Jesse.
For reals!!!
Nice going, well explained.
One more option for campers and boats.
At the second option ( smart switch) with a addon PV panel ( solar ) you may work out that the engine generator dose the bulk 14.4 what will result in 13.8 volt steady charge , the PV may work the float for the deadcycle battery.
Obviously the PV is directly attached to the house deep cycle
Thanks for sharing!
Great Video Jesse,
Your just full of surprises ! thank you for making this video !
Never thought of option # 3 , what a great idea and so easy. I 'm planning on building a pontoon style house boat with A/C , bar style refrigerator , microwave , etc for small equipped kitchen . Solar being the main generator for the house batteries . So for after sundown travel or just charging , the old VW turbo diesel drive engine can turn a School Bus / Truck alternator as these produce high amps even at idle and can all day long if needed . Some had manual adjustable voltage regulator output settings . I was going to use a battery isolator for the 2 battery systems ,but option 3 allows for higher voltage output for the Deep Cycle Batteries and DC to DC for the starting battery .
Hi Wayne! Thanks for your feedback, it's nice to hear you enjoyed the video. And what an exciting project your are planning, wow. Great idea to use the heavy duty schoolbus/truck alternator with adjustable voltage output, simple & very effective. I would love to hear / see how the project turns out!
Hello. So considering the normal car alternator uses a 12v battery, how can you wire a bigger battery pack(48v) without roasting the alternator ?
@@apocalypseapocalypse3550 1st (better) option bigger alternator
2nd intelligent charge controllers / battery isolators in sequence; each set only triggers after the previous completes its charge instructions, i.e. 1st starter battery > then house batteries. Charging them as separate banks would keep the alternator draw separate, minimizing its workload. Really only good if your engine is running a lot.
thank you for this video .. really enlightening i was very confused about these systems and no one seems to explain it so simply..
I am glad to hear you are enjoying the channel Valkyrie, thank you for your message. All the best, Jesse.
Absolute genius. I never quite understood why my leisure battery had such a problem with fully charging, despite being replaced and its because mine is the layout you explained where the starter battery is always getting the priority of charge. I will defo be changing this when I get my lithium replacements in change for Lead acids.
Its good as you said for if your starter has a problem and you can take the current from the leisure to get your engine battery going, but I dont need that as a priority, as im on a small lake with a good powered outboard to get me back to safety.
I simply added another alternator! One for charging the house (camper) battery and another alternator for charging the truck battery. It has been working on my camper with the usual repairs and battery replacements. The two systems are completely independent from the other. I have lived in it for 38 years. I am also independent.
Hi Bud, thanks for sharing your story. Great setup! Yep, two completely independent systems gets you great reliability and efficiency. Well done!
All the best, Jesse.
bud irving - Where did you connect the 2nd alternator? I'm trying to understand some of this, I'm a 63 yr old gramma here, so please be patient, as I don't know what the alternator in connected to.. : ) I'm considering using an inverter in my little pickup on a cross country road trip. It says to use it with a deep cycle battery, so I had to look up "how to charge deep cycle battery" and it brought me here haha. Anyway, is this something a car mechanic would know how to do? Thanks.
@@annwithaplan9766 hopefully you had an answer. A simple 400w inverter that you plug into a cigarette lighter is great for most needs. You cannot cook with a hot plate of course
@@vanderumd11 could you reliability charge a deep cycle battery using this method, as long as the engine is running?
Thank you so much Jessy , you reminded me with my collage time, I should call you professor Jessy! Thank you sir for explaining things that well
And thank you sir, for putting a smile on my face! All the best, Jesse.
Great video thanks. Your replies to others answered my questions, best 1/4 hr I have spent this week!
Hello Hendrik, thanks for you message. Your feedback is one of the nicest compliments to receive. I am glad the video was useful for you! All the best, Jesse.
But if you play it at 1.5 speed it would be the best 11 minutes and 25 seconds that you would have spent that week
Excellent video. All the internet knowledge but collated in a single, and short, place. Thanks!
Thank you Tom, that is one of best compliments this video can receive. I am glad you enjoyed it! All the best, Jesse
Thanks for the great analysis. I had been debating between options 2 and 3 and you helped me settle on Option 3.
That is great feedback to receive! I am glad the video helped you in your decision-making process. Good luck with your project and all the best, Jesse.
How could you wire a 48v battery pack to a 12v car alternator without blowing it up?
Thankyou. I am battery n solar power challenged. Good to check yr vid out. I did not understand much of the vid but was still good info. A start for me. :)
Glad you enjoyed it
I was searching for a explanation what I'd need. Nowehere I found it so well explained without all the b*llshit. Down to earth dude, so very happy with your video. Thnx Jesse keep it up!
Haha, now that is a great compliment, thank you! I am glad to hear the video helped you with your project. Good luck and all the best, Jesse.
@@SolarSolution no problem! Now the only thing I'm trying to find out is whether I need a dc-dc charger which is insulated or one which is non insulated. Goes in our van which already has solar power but just not enough since it's now winter in Greece and the sun is not high enough on average. Do you happen to have a video or some explanation about what to choose somewhere? Kinda hard to find a solid answer..
Sorry, I do not have one yet. Great suggestion though, I will add it to the list! Enjoy, Jesse.
This is a great video, thank you for sharing, I have watched this several tines and I'm sure, I will watch again, great job!
Glad you enjoyed it!
Pretty good video. The deep cycle batteries clearly benefit from proper charging to last. Starting batteries on the other hand are very tolerant of non ideal charging and can still last long, but only as a starting battery.
Thank you for your contribution BearChow, it is good to hear you appreciate the video. All the best, Jesse
Thank you so much for all the clarity on this matter! Very well presented and explained. Cheers!
Hello Garrett, thanks for your message! It is good to hear you enjoyed the video, you are most welcome. All the best, Jesse.
I went with 4th option on my ford truck. 2nd alternator with program regulator to set battery type. this was not simple and had to change belt and add pully . make a mounting bracket . great job explaining the options.
Hello Robert, thank you for sharing. That is a very nice option as well. A bit of work indeed, but I am sure you are very content with it. Enjoy! Jesse.
adding a 2nd alternator is a much better idea than overloading the regular alternator, and risk ending up with none.
I am just now buying a Ford...which program regulator did you select?
great clips man! I like the "quick and dirty" bush method! LOL!!! thanks!
Wow. This is the best vid I've seen in a long while. Great explanation.
Glad you enjoyed it!
What a great guy, easy to listen to, great factual information.
Glad you enjoyed it!
It's been 5 months since your last video. We're all waiting for more!
Haha guilty as charged! I have been putting a lot of work in new content, I am sure you will enjoy what is to come: Within 2 weeks is my promise to you. Thanks for your message! Jesse.
I had this cool solar charge/Shore power system design made and super happy with it only to realize that wall power is maximum 16 amps where I live😂 so I'm now looking into this don't feel like waiting for days in case of bad weather for my batteries to be charged.
Hello Milo, thanks for your message and for sharing the plans on your project. Good luck! Jesse.
Fantastic explanation! Both the simple language used and well timed diagrams. Thankyou!
Thanks for your message Ash, I'm glad it was helpful!
Awesome video Jesse, straightforward, clear and simple to understand thank you.
Glad it was helpful!
Its a beutiful explanation...i have applied a change over manual switch that directs the plus wire from the alternator that allows one battery to be charged at a time.
Hope the 100 amp house battery is not too much a load on the alternator that is designed to charge 40 amp engin battery
It is good to hear you enjoyed the content. Just a tip: Be mindful of the potential damage to alternator electronics during a momentary 'no load' situation as you would change from one battery bank to the next. All the best, Jesse.
What an amazing video! Instant subscribe from me. I love condensed understandable information like this. A golden video.
Thanks Corey, that is great feedback to receive! I'm glad you enjoyed the video. And welcome to the channel! All the best, Jesse.
Best TH-cam video I've ever seen.
Great video! Super helpful. I would love to learn more about option 3, using an external voltage regulator from the alternator to a LiPO4 house bank with a dc to dc charger for the starter battery. How do we maximize charging of batteries without damaging the alternator while ensuring the starter battery is always charged? With the standard 80 amp factory-installed alternator be up to the task of quickly charging a LiPO4 house bank?
Hi John! It's good to hear you found the video useful. As for your questions, I would like to draw your attention to the pinned comment at the top. All the best, Jesse.
Thank you for making this simple to understand!!!
Hello Roger, thanks for your message. It is good to hear the video was easy to digest! All the best, Jesse.
This is what i was looking for.
You enlightened me sir.
I consider to use the third option for my battery bank.
So what would be your advise for the suitable external voltage regulator for charging of a 12.8V 320ah Lifepo4 Battery?
Wich one to choose?
There are so many on the market.
What fuse to use and what power?
11:35-12:04
I was just pondering this same idea when, he grins and mentioned it. Down and dirty lol 😉😂
Excellent informative presentation. Thank-you!
Thank you I am a new subscriber to this I like working with batteries like 18650 batteries but I really like learning as much as possible
Welcome to the channel Omar! We seem to share a passion for learning, that is great. Enjoy the channel's content, all the best. Jesse.
Excellent video. I’m keen to learn how I can add a jump start function to my system.
I have starter battery > dc with inbuilt regulator and solar input > lithium house battery > inverter and 12v outlets.
I was wondering if I could add a smart isolator solenoid ( like you would use use in option 1) that has an override jump start option that I could wire to a push button switch in the vehicle instrument panel.
Eg starter > smart isolator > dc > house etc.
Or would I have to run a seperate circuit with some kind of link switch that bypasses the dc charger to link and jump start?
that was awesome helpful.. thank you so much, enjoy your meal..(i watyched this so many times and will be watching with my son till he can explain it :P)
Glad it was helpful!
Fantastic! Thank you, so many questions clarified…
Glad it was helpful Tim!
Great explanation. It has motivated me to fix my RV house battery charging system. The current system is 2 x lead acid batteries of about 140 AH capacity. They are used to power electronics, fridge and a CPAP machine when shore power or the Onan generator is not connected.
Charging is by a 12v charger fed by shore power or the Onan generator. There is also a relay activated connection to the RV alternator but I have disconnected this for obvious reasons. I have also installed a solar panel on the roof. The solar panel includes a charge controller that I have connected directly to the battery. The panel supplies up to 2A when the sun shines.
I want to reconnect the alternator to provide more charge when the RV engine is running but I am concerned that having 3 sources of charging current might cause problems. Is there such a thing as a multi port dc/dc converter that will manage the 3 inputs to give optimal charging for my batteries.
Awesome. Exactly the information that I was looking for. Thanks!
Hello Ashm. Yes indeed, I have solar courses available on Udemy, here is the link: www.udemy.com/user/jesse-gorter-3/
Excellent. Thank you for taking the time to make this.
You are welcome Jeff, I am glad to hear you appreciate the video. All the best, Jesse.
Great information. I have one question. If I am charging 2 6 volt batteries ran in a series how would I connect the charger to each battery. Thanks for your help.
Great video Jesse, I do a lot of installing of these systems but have never really considered your option 3 although I have heard mention of it.... I.will investigate the availability and economics of the external VR, but convincing paying customers of the extra expense is another task...lol..
Hi Graham, it is good to hear from you. I am glad to hear you were still able to learn something from this video. Good luck and all the best! Jesse.
if they don't pay for the right setup now it will cost them in the long run.
Brilliant. After many videos which have been helpful and learned a lot, this ties them altogether and makes sense. The best I've heard.
.Questions... should an alternator be reset to 14 8 v if possible for the house batteries and the the controllers to the starting batteries take it down to 14.4.?,
Great explanation.... thanks.
Could you follow up with recommended components especially for your recommended option please? Love the Kiss analogy!!
Hello Robert, thanks for your message. Your question makes a lot of sense, though the final selection of components depends on your specific system details and performance requirements. Good luck with your campervan-project! Jesse.
Finally a simple clear explanation. Thanks.
It is good to hear you appreciated the video, thank you for your message. Jesse.
this might be the best video on the subject.
That is nice to hear, thank you for your message!
Thank you sir, been looking for this information for years
Glad to help
GREAT explanation, very understandable to the novice, 😃😃😃😃 Thanks
Thanks for your message William, it's great to hear you enjoyed the video! All the best, Jesse.
Great info , thanks , I’m deciding on best setup for my RV , and I want solar ,generator ,truck alternator and when in hook up to AC power all ( smart charge truck and RV house batteries, probably using smart battery isolator switch
Hello Djpitr, thanks for your message. It sounds like you are working on a nice project for your RV, good luck and have fun! All the best, Jesse.
For personal advice you can contact me through www.solarsolution.co/contact
I have been trying various options for my Jeep (mobile ham radio) for my dual batteries. I started with a VCR and deep cycle agm for both. That worked well when I was driving a fair distance daily, but as things changed (even before covid), I started having batteries go dead over long weekends and stuff. This video explained that my charging system wouldn't charge the AGM well even on longer trips and likely killed the battery capacity, so it drops more easily! It does pass a starting load test and a .2C draw, but the voltage drops off a cliff immediately.
(See below for further comments on VCR.)
As covid hit, I decided to implement solar while parked with a decent charge controller set to AGM and cheapo panels. For the one battery that survived (crippled a bit though), that has worked wonders. (Now to design a solar tracker that can permanently mount on the Jeep, stow when driving and activate when parked.)
More recently, since I had it sitting in parts for a decade, I installed the solenoid that allows using the house (auxiliary) battery for boosting.
Now you provided the last piece of the puzzle as to how I can use 1 solar charge controller or AC battery charger to charge both batteries. The DC to DC charger. From reading specs, I believe it will kick in when the main battery goes above threshold and will then begin to charge the house (auxiliary) battery with the correct profile.
So my plan now is to remove the VCR, add a DC to DC charger, keep the emergency solenoid, replace main battery with starting instead of deep cycle and get a new AGM deep cycle house (auxiliary) battery.
I may even duplicate the DC to DC with a larger lithium battery for the radio(s). That can't be my permanent house battery, as I am in a part of Canada that gets too cold for part of the year and I want to use it for portable etc.
Comment on VCR: Many people spout all kinds of mistaken information about these and what happens to the battery banks and charging. There are two types, single and dual control. Single only monitors the main battery. Dual monitors both.
In both cases the control is simple from an operational standpoint. When the voltage is above a certain level (13.2V on mine), the relay kicks in. It doesn't know or care about the SOC of that battery, only the voltage level. So when the vehicle starts and pushes the voltage up within seconds, it connects (unless yours has some kind of delay timer). When the solar kicks in and brings the voltage over that cut in, it connects.
When the voltage drops below the cutoff point (12.7V on mine), the relay cuts out. For starting lead acid batteries, including AGM, that is a fully charged voltage.
So, yes, it will draw down both sides until the measured side is below the 12.7, then cut out. Of course, when connected with a relay, both sides try to be and are usually at the same voltage. (I found there is some "chattering" as voltages recover, then get pulled down again and so on.)
After that, even if you continue to draw on the house batteries, there is no draw on the starting battery from that side of things unless it again goes over the cut-in voltage. Of course Ignition Off Draw (IOD) still exists on the starting side.
I hope that cleared some stuff up.
Great video one of the best on TH-cam and a great help.
Hi Jess. Great video's. Explain the best wiring for a duel battery truck with a duel battery trailer both equipped with solar panels.
Thanks and great suggestion Jaco!
Thank you for sharing, I'm putting a 2nd battery in a 1987 gmc truck, got a Cole Hersee. 24063-BX solenoid, run from main battery positive to solenoid, out main lug otherside to second battery positive. Ground negative from 2nd battery to chassis. Can you please recommend gauge wire and size fuses in between? In any event thanks!
I am late finding this video I running a 250amp alternator and a 12v 60AMP lithium deep cycle battery and plan on upgrading to a dual battery setup. Reason why I have aftermarket sound system in it that one battery cannot handle that load. What is my best option?
General question for all. I am planning on using the third option for a boat installation of regulated high output alternator, lithium house bank and two AGM batteries ( starter and bow thruster). The 30 amp dc-dc charger will feed into a MOSFET isolator that is then feeding into the two identical AGM batteries. My question is: If the lithium batteries shut off for any reason while charging . Will the AGM batteries absorb the voltage spike or power dump and in doing so protect the alternator?
Hello, wonderful video's. Can you tell me if you are driving and the solar is putting charge as well as the alternator, will this help stop the alternator over heating while charging lithium batteries?
Great video!!
DC- DC second option.....
Question..what happens iif I have a battery switch AFD type [off,1,2,all]
1 connected to starter
2 connected to house
on 2 position......the alternator still charge the starter battery?
Thank you!!!!
Thanx Jesse great content n I'm coming to you cause your the guru of generators etc.I have a 2020 jeep wrangler jl 2.0turbo with Etorque. Doesn't have a alternator,ork?
In a powertrain fitted with eTorque, a belt-driven motor-generator unit replaces the conventional alternator on the engine. This motor-generator unit performs several functions in addition to the standard operation of the alternator, which is to provide electricity to keep the vehicle's battery charged. But in an eTorque-equipped vehicle, the electrical system is significantly different than in a conventional vehicle.
With the eTorque system, the motor-generator supplies electricity to a dedicated battery pack used to gain several advantages. The motor-generator unit delivers a 48-volt current to a 430 watt-hour lithium-ion nickel manganese cobalt-graphite battery whenever the engine is running. The battery pack array includes a 3-kilowatt direct current-to-direct current (DC-to-DC) converter that changes 48-volt current to 12 volts. This enables it to power the vehicle's accessories, which run on a typical automotive 12-volt current. Also, it allows it to charge the vehicle's conventional 12-volt lead-acid battery.
The motor-generator also creates electricity during deceleration and braking through brake regeneration. This process captures energy that otherwise would dissipate as waste heat. That energy flows to the 48-volt battery pack for storage and keeps the battery pack at a proper charge level.so this is capable of handling a winch extra lights etc.my question is,I have a large stereo system that's going to be installed that will total at least 975amps, I changed the stock 12volt battery to a 750cca agm battery and added a limitless12k lithium battery capable of handling 10000watts-12000watts at 14volts.all wiring will be at 2/0 awg ofc wire.also a 500amp batttery isolator.I'm planning on installing a 100watt solar panel that they make for the hood of my jeep as well as a redarc bcdc dual battery charging system that can charge from solar panels.will the generator be able to handle that much amperage?I spoke to other guys with same vehicle that's pushing a lot more than that and have no issues.just want to be sure you it will be ok.
Outstanding video, can't wait for life po4 solutions
Thank you for your message Zoltan, it is good to hear you enjoyed the video. Your suggestion makes a lot of sense: I will add a video with a specific focus on LiFePO4 to my to-do list. I will let you know once it is online. All the best, Jesse.
Wow thanks Nice info 👍 you the man....lol thanks for sharing your video with us
No problem 👍
this was a damn good video. learned a lot! Thank you!
Haha that is good to hear Cody, thanks for your message!
Great presentation - Thank you Jessie!
Glad you enjoyed it!
Great explanation! Used #2 for my trailer. Pax tecum
Thanks, that's great to hear! Et cum spiritu tuo.
Thank you so much for your video,)
Really good explenation ..
Glad you liked it!
On the DC/DC charge controller setup, do I need to run the ground back to the starter battery like in the diagram, or does a ground to the vehicle frame do the same?
I have been waiting for this video, you full cleared up the last bit confusion I had on using a Solenoid. I am currently setup with option number 2, not exactly sure what the benefit of option 3 is over 2, I am guessing since your going straight to the house battery you can work at the max amperage of the Alternator to speed charging on the house battery, while using the dc-dc to control the charge on the Starter.
I upgraded my alternator to 200 amp alternator and put a 40 amp DC-DC so I get fairly fast charging on the house battery with out going over the maximum charge current rating on my AGM, which would be my one concern with going with option 3. I also did some testing before changing out the stock alternator and found my van used 45-50 amps just to run and also found out that the stock 130 amp alternator only put out 60 amps at idle so when I originally installed the DC-DC, I was pulling more amps than could be supported by my alternator causing my start battery to discharge.
Thanks for covering this subject for me I will be sharing this video on my feeds.
Jason
I'm glad you liked it Jason. Congrats on your new setup, great job!
Out of curiousity, what is your van?
Great video!!!! Thank you!!
Hi thanks for your video. I wondered what your opinion was on the Victron Argofet, as this setup isn't covered in your video (i dont think anyhow). Many Thanks
Thanks for the great information! Where do you recommend getting an external regulator and dc/dc charge controller to set up the third option?
Hi Dave, thanks for your message. As for your question, I would like to draw your attention to the pinned comment at the top of this section. All the best, Jesse.
Foe example 3 if your house batteries are lithium iron type would you not have to use a DC-DC charger to limit the charge rate into that battery bank and therefore protect the alternator perhaps you need two DC-DC charge controllers to use the 2nd one for the starting battery from the house battery bank?
Good job! I was going to comment on that first video with the Li install but didnt. I am in the same situation...do I also install the dc to dc charger or not? I will probably go that route. Keep doing vids...its appreciated.
So Jesse, could you please give an example of of single stage charge? For example, charging the house battery via a traditional 220V mains charger (old school type).
hello, would it prevent damage to battery if solution 1 is choosen with some full charges from time to time with a specific charger?
AMAZING VIDEO!!!
Glad you think so!
Excelent video, thank you very much!
You are welcome!
would it be possible to have a starter battery bank on its own circuit that is open when a heavy load is needed? like a soft start or pony motor for high voltage appliances? close the circuit to those cells when not needed?
Well done and very informative!
Thank you Old Wrench! It is good to hear you found the video informative. And I just wanted to say I like your username haha. All the best, Jesse.
Jesse, thank you for all the videos. My system has a starter battery - currently on its own battery switch and completely isolated from the 2 house batteries. I would like to link the starter battery to the house via the DC DC controller and therefore allow the alternator to also charges each house battery. how do you suggest I proceed? I do have a 1, 2, 1+2, off switch for the house batteries. shall I just connect to the 1+2 when running the alternator?
Thank you again very much
Thank you... very helpful. Considering option (3) from Your video noted below, I was wondering if you could recommend an External Regulator, and a DC /DC charge controller combination? Perhaps something off of Amazon
Thanks again.

Option 4: install a 24v alternator. Bypass the internal regulator. Connect the 3 phases in series with one winding reversed. This will give you about 100v single phase. Rectify through Schottky diodes and put through a MPPT controller. You now have more power than a heavy duty alternator
Thanks Lexie, great feedback and an interesting option. Thanks for sharing! Jesse
I wanted to do this with many ac parralell connecting solar panel inverters advancements..therefor direct powering of some powertools from alternator, cannabalization redundancy, parasite loss management, segragating solar panels to appliances.. But the marketplace is not developed especially at 110v
If aftermarket contoller solved batteryless bootstrap start up of field coil, and could switch between nominal 12vdc charge controls and 110 approx crude ac output..perhaps exists in high price marine market and historical Frankenstein diy.
What?
