      I ordered my truck with a second alternator with the thought that I could use it to charge a DIY electrical setup in my truck camper. The box of AUX switches is setup for 30amps or less. Im not really sure how to get the power from that second alternator to the camper in the best way possible. Mind you this is only while driving. I have a 2500 watt gen to charge while parked and 200 watt solar to top off. I like the idea of alternator charging for two reasons. One, to back up the generator if I need to conserver propane. Two, to charge up between campsites since the gen is a bit noisy for any potential neighbors I like have the batts topped off before I park.

    I think "redundancy" and "travel style" determine whether B2B makes sense to include in the charging mix. Weather and angle to the sun (think Alaska) often greatly diminish solar charging contribution. Driving every 2-3 weeks vs. every two or three days is informative.
    You're assuming a huge battery bank (e.g., air conditioner) and possibly over-relying on good weather. For 200-300AH banks, most can simply upgrade their existing alternator (to max allowed by manufacturer as a "direct replacement") and use a B2B charger. For example, my 2006 Dodge 3500 sprinter allowed for a 200 amp alternator. Calculating a load on that Bosch alternator, I could leave 20% in cushion/reserve and still use a Sterling 1260 charger, which I typically leave on 50 amps but sometimes 60 amps.
    If I had a larger bank 400-800AH, I'd still do an alternator charger, either direct replacement or second alternator, especially if I drove a lot.
    Generators are ok (I carry a Honda 2000), but they suck in terms of noise. In a good boondocking location, running a generator doesn't endear you to other campers.
    I'm a fan of your videos, but this one might have been a little underdeveloped in terms of pros and cons basis the application in one's rig. Like solar, once the capital outlay has been made, alternator charging is essentially a free bee, albeit a trivial amount of additional expense in fuel. The biggest upside of alternator charging is redundancy: just another source in one's charging arsenal.

      YEA, THAT'S ABOUT IT.........I'VE TRIED AND DEVELOPED ALL THES ALTERNATIVES AND THEY ALL HAVE THEIR LIMITATIONS WHEN DOING LONG TERM OFF GRID............GENERATORS ARE HORRIBLE....BUT SOME TIMES NEC...LIKE MAYBE A WEEK OUT OF THE YEAR, MAYBE..........ALTERNATORS PUT A LOT OF WEAR ON THE ENGINE, IF OVER USED.......IDEALLY THE MIX WOULD BE 90 PERCENT SOLAR, 10 ALTERNATOR AND 5 PERCENT GENERATOR, WORSE CASE SENARIOR, HEATING IS THE BIGGEST CHALLENGE, WHICH CAN CHANGE THE ENTIRE PICTURE AND ELEVIATE THE NEEDS FOR ALTERNATORS AND GENERATORS, WHAT EVER YOUR HEAT SOURCE MAY BE..........GAS, PROPANE, DIESEL OR WHATEVER, AGAIN MERELY AS ALTERNATIVE BACK UPS....

    One needs to consider their own situation. Nate, you live in the mountains of Colorado, and mostly enjoy dry and not-so-hot summers. We mostly travel in the southeast, and thus regularly face hot and humid situations -- where AC is important!
    Given our desire for AC, we have a Sprinter (170) with 810Ah of lithium batteries and 525 watts of solar (this is all 12 volt). We are adding a second alternator, which allows us to quickly charge up while doing just a bit of driving. Notably, a large battery bank allows us to to better separate periods of charging from periods of consumption.
    BTW, we prefer to park in the shade when it is hot, which avoids heat gain but reduces solar generation.
    Finally, I will add that "the good news about a big battery bank is that you can run your AC (or anything else) without worrying so much about consumption." The bad news about a big battery bank is that you gave to charge it! A second alternator is a great solution. I am happy to have a single internal combustion engine on my Sprinter. A generator adds extra weight, takes room, requires maintenance, etc. I already have an ICE under the hood. Better to use that sophisticated engine to run a 2nd alternator instead of fooling with a generator. At least that's how I see it.

    I have the solar and generator options but still went with the 30 amp alternator charger for my 824 amp/hr bank. I did it mainly because I have a 12 volt dc refrigerator that will be running as we are driving and I want to keep the system topped off with that charger and use the other options when camping.

    Thanks for the video Nate. Your broad expertise combined with your skill of distilling complicated topics to actionable plans makes you the van builder's oracle. I think most of us viewers will benefit from a more comprehensive exploration of this topic than charging a large battery bank from empty to full. One of the reasons I installed a large battery bank (600Ah-24V) was to create time between use of electricity and recharging.
    I usually start an adventure with full batteries charged from my Multiplus plugged into the grid. Since I don't currently have an air conditioner, I can easily spend a week or more off-grid without charging at all, which is nice if I'm posted up at a backcountry ski area with cloudy skies or snow on the solar panels. Solar is my primary charging source and it eventually tops off the batteries. But in the odd case I'm running low on power, the reliable but slow charge rate of the DC-DC charger is very welcome. When you're out, a little matters!

  • @andrewkrenske7263
    @andrewkrenske7263 ปีที่แล้ว +6

    One major benefit of some of the better dc-dc chargers that you don’t even mention is that when your batteries are full and you have solar power coming I. they will trickle charge your starter battery.
    A combination of solar and dc-dc is what you should be recommending

    My charging is 95% solar, but alternator charging saved my bacon when I got trapped on the Oregon coast in wildfires. My array was putting out *1.6% of rated power* at local solar noon in the smoke haze. For a month.

    I am using dual 200 amp alts on my rig for 3 years now, one came stock and I added one. Got it from a wrecked truck with the same engine for $100 (like new) and had a local welding shop fab up a bracket for $125 and a new longer belt from Autozone for $48. I have 600 watts of solar and use the alts only when it's cloudy/rainy/AC needed on a hot day. No issues and no worries so far. Just up the idle to 1200 rpm and 4800 (let's round down to 4000 watts) watts will charge up the batts fast on the days I need it.

  • @alainmasse5461

    Love your channel!! I have a Sprinter van and I live in California. Personally alternator charging is a must. It keeps my Isotherm fridge cold while driving and it tops up my auxiliary battery bank 100%. Redundancy is key for me in case one fails or I don't have enough clear days for my solar panel. I love my solar setup but it is not much help in Tahoe when it has been snowing for 3 consecutive days.

  • @Bwanar1
    @Bwanar1 ปีที่แล้ว +7

    In addition to your just having solar, I think you need to factor in the time of year and latitude you are going to be traveling in and the fact that you won't always have sun; sometimes for days. I think alternator charging is a great thing to have, for additional charging capability, even for a back up. When you are traveling down the road, the additional stress the alternator will put on today's large diesel engines is negligible at best. Solar is by far the most expensive option. All things considered, a generator is your best bang for your buck, and super convenient if you are burning the same fuel from a large tank as your engine does.

  • @gfaucett
    @gfaucett 2 หลายเดือนก่อน +1

    I hear a lot about different charging solutions for RVs-DC-DC charging, solar, generators, etc.- and it's great that we live in a time when there are so many options. Ultimately, the best option depends on how you travel and the sources you have available for charging. In my case, I've recently upgraded my setup to include 2 200Ah LiFePO4 batteries in parallel, along with a Victron MultiPlus II charger/inverter.
    The Victron MultiPlus II is a versatile device that acts as a charger and an inverter. It seamlessly switches between shore and battery power, allowing me to make the most of the 50-amp service at RV parks every night. This setup has been ideal for my large Cameo fifth wheel.
    However, if one lives off-grid more frequently or parks without access to shore power, other charging solutions like solar or DC-DC alternators might be more suitable. Solar is excellent for off-grid living and provides a sustainable way to charge batteries, providing you're in an area where there is sun or you aren't parked under shade. DC-DC charging from a vehicle's alternator or an additional 2nd alternator can be a great option for charging while driving.
    It's all about understanding your usage patterns and choosing the right solution. While my setup works well because I mostly stay at RV parks with shore power, someone who frequently boondocks might prefer to add solar or DC-DC charging.
    For now, batteries, a good charger/inverter, and nightly shore power perfectly meet my needs.

    Hello Nate,
    I have finished the install of my Battle Born / Explorist Life install. I have been on the fence about the alternator charging prior to your video. I have a factory 2nd battery that was factory installed that the alternator charges already. I installed the wiring but did not install the DC to DC charger. I decided to take your advice and trust my instincts. I have a small Honda generator that if my solar falls short, I can supplement power from it.
    I want to thank you for all the information, videos etc. I am very proud of the results I have gotten. I am the guy with average electrical skills you often mention. I know without your expertise my great results would not have happened. Thank you!

    to protect it regardless of engine RPM. (300@hr lithium batteries). Internal regulator had no current circuit. Works great, never have to worry about alternator burnout. Simple PWM circuit. I charge the batt's to 80% state of charge, last longer that way.

    Hey Nate, first want to say thanks for all the help with my 2022 transit. TOPIC ALTERNATOR CHARGING. Wish I would have gone with a dedicated wake speed but I ordered my van way back in 2021 with dual. I am having a hard time implementing third party high power mode and or SEIC high idle. I have attempted several methods with grounding pins under the driver seat 3/1 as well at using the higher spec interface grounding options with no increase in voltage. Currently power a victron 30 amp Dc/dc and a sterling 120. It pulls well at idle but never ramps up rpm’s and don’t want to destroy my alternator, I have also wired an emergency extra charge source via an inverter that feeds my multiplus. I have dual transfer switches so I can feed the multiplus from my battery bank and it thinks it’s shore power via generator or switch to direct from ccp2 giving me an extra Dc/AC/DC charger and resulting in 250 amps from my batteries. I know your crazy busy but I am at a dead end

    Hello
    I have the victron orion 24 volt, 15 amp alternator charger installed on a ford transit with 700 watts of solar on the roof.
    This is my backup for when you have multiple days of cloudy, snowy or rainy weather , parking in a dense forest when off grid , in between canyon walls .. ect. Alternator charging this way gives you options for very little money.
    I love this unit, it works great and is reliable so far . IMPORTANT!! Wire in the alternator charger with an on off switch so that it can be used selectively when you need it.
    In real world conditions my Victron orion Alternator charger puts out about 320 watt , 11 amps at 27+ volts . This works out perfect for me. If the engine runs for a 1 hour this gives me 19000 WATT MINUTES of charge. I would not , do not , use alternator charging as a main wattage source.
    I do like your vids. Have been following you from back in the mountain bike days.
    ... side note.. the WATT MINUTE is so much easier to use as a unit of battery useage and keep track of in my head.
    I make a cup of coffee. The coffee maker runs for 2 minutes at 1750 watts.
    2x1750= 3500 watt minutes.
    Subtract 3500 from my total watt minutes the battery bank has and your done .
    Run the alternator charger for one hour and I can make 5 more cups of coffee. YES!!
    Sorry for the long post.
    Mike

    Good one I bet there will be some discussions on that topic. Look forward to seeing the build. - But as a North European Vanlifer, not very useful for me. We hate generators here 🙂 - and we actually don't have very much sunshine in winter time - SO we usually have 2 systems running to charge the batteries. Solar panels AND DC/DC charger from the generatos also. I even swapped to a bigger Amp generator for mine.
    Oh, and not very many over here have aircon units in the back - and only newer cars have in front.

    Your calculations at 2:30 mark are theoretically possible but will take longer in practice. I have 200 amp 12 volt lithium batteries being charged by a 20 amp dc/dc charger and the charger may start off at 18-20 amps into the battery, but slows as the batteries get above about 90%. From 10% to 100% regularly takes over 11 hours with the engine running. It’s still way better than trying to use solar panels though.

    I have a Class C - older model. I have a Generator 4000W, plus an alternator charging from engine battery. I don't have any solar yet. However, I would not do away with the alternator charging because ... it is silent. The generator makes A LOT OF NOISE. You arrive at a residential destination lets say, and its nighttime. You cannot use the generator there, cops will be called. But if your alternator worked while you drove, then you have enough juice in batteries to power up lights and basics. What happens if solar is not working optimally AND Genset gives you trouble? At least you have the alternator back up. I think you should always have it. Good video, learned something. Thank you!

    Thanks for the video. Please consider my case, with a ModelY as my Tow Vehicle. I'd like to keep my vehicle range as high as possible, so I'm considering not charging my pop up camper battery. Most use is weekends with shore power. Can I just clip the battery charge wire from the 7 pin connector, and use a regular battery charger from shore power or solar? Is it possible to run my camper lights (including tail and brake) from the camper battery? I'm planning to swap bulbs to LED, perhaps the draw from LEDs isn't enough to worry about? Thanks!

    there are many use cases where alternator charging has other systems beat. In my case i started with a victron 30 am dc to dc. but while driving (class c motorhome) i switch my fridge to electric, that takes up 1/3-1/2 of my dc-dc, then my kids are on computer or game systems. and its the rest of the power is used up if not dipping to negative already. Not to mention the AC in the dash can not cool the coach and its surprisingly hot. so when i fire up the roof ac its using 1500 watts. So i added 1600 watts of solar panels to my roof, thats the most i could physically fit. they are flat on the roof so most of the time they are in the 1000-1200 watt input range. so i am still short on power. not to mention i like driving when its dark because its usually a bit quieter and less traffic. So the solar is useless then. I do have a onboard generator, but the wife and kids always forget to start it before the batts die and leave it running when its not needed. Plus it just burns fuel because its a fixed speed 4000watt onan, it just adds more stuff to service and keep track of and interact with especially when driving in the mountains, sometimes it dies and you gotta stop and turn the elevation adjustment. So i ordered the alternator kit with lithium regulator and harness like you showed here in a 200 amp version. That should cover all my basis when i get where im going the batts will be full and the extra ground deployable panels will cover the needs most of the time. the generator is my last fail safe option

Is there really that much wear and tear on the vehicle to charge the batteries while driving? I'm only using the diesel heater, refrigerator, and an outlet with USB for small items / appliances. I intend to make it a 3 battery bank, the 2000W inverter upgrade is going in now and I'll installing a fan, a water pump, and another 20amp outlet for use with an infrared hotplate that will surge up to 1800W at the most. Isn't the belt on the alternator going to turn anyway while driving? I'd have to be parked for 3 or 4 days depending and be completely overcast before considering running the engine. For my needs due to my work schedule vacations won't happen where I get extended periods of time and 3 days is about the most I'll be doing for my needs.

    Hi Nate, my name is Otto. I have really enjoyed watching some of the videos you have posted with a vast amount of information. I see that someone else has posted a question regarding running his truck with dual alternators. Have you had the opportunities to work on the 2023 Ford Transit Trail? We have ordered one, due to be delivered in 10 to 12 months. I ordered with the Dual alternator which is an option. With the little information I was able to gather from the Ford Dealer and watching few of the feedback in the Ford Forum, it seems that the Trail package electrical system is wire in such a way that both alternators are charging a couple of AGM 100 Amp/hr batteries and they provide some additional 12V switches and a fuse panel. At first I was thinking of having the local Ford dealer disable the monitoring and control of the second alternator, the service writer said that it can be done. The more I have thought of this, I do not believe it is a good idea to have the 2nd alternator reprogram because this may affect some other parts of the system. I ordered the 2nd alternator because I had in mind to dedicate it to charge a couple of 100 Amp lithium batteries but I thing that this is going to require a bit more planning. Lots of questions are starting to popped in my head like, what is the proper to tap off these AGM batteries to dedicate the wiring to feed my lithium batteries and then how to isolate the starting batteries so that the solar panel only charges the camper side lithium batteries, etc., etc. Then design the electrical system to determine what will be all the Victron components needed (dc-dc) charger, inverters, Dist System, etc., etc. Have you had some insight on this new Camper VAN Trail Transit package?

    I sort of disagree. Solar is amazing when it’s sunny. We did a two week road trip with almost zero sun the entire time. Without a second charge source we would have run out of battery power. Also I will say this even though I’m a huge fan of Victron their dc-dc chargers are severely lacking. No ve.direct, no dvcc, no external control with can battery, and low output. Until Victron dc-dc comes with a higher output with those options I’ve seriously been considering a new sterling (all red box) unit. Price is was lower per amp and go up to 200 amp (no van can handle that but the 120amp model would be close).
    Of course if Victron ever release a better unit I’d swap in a heartbeat. I went to intersolar in 2019 and was told better units with those features would be coming soon. I understand the pandemic hit but hopefully something better comes soon.

    - before thinking of your options (charger, boost converter) there should be an investigation how much power an alternator is able to produce. Also take in consideration that the car itself may consume some of that capacity. Perhaps the rest is not worth the invest.
    - instead of your options I would think about an intelligent regulator (I know best Sterling) on the alternator - also in respect to a smelly😉 test from Victron on an alternator at 50% rpm. This is only possible, if both batteries (Car and Camper) are the same technology).
    - your suggestion about an additional alternator seems to be big - aren't there also smaller / cheaper? But I also would pretend on that an additional alternator has a modern intelligent regulator.

      So instead of a $250-$2100 solution we could be talking about a $50 relay for campervan folk. Victron Cyrix-ct for example if we want to stay with Blue. Changes the economics quite a bit.

      @@fratermus5502 This intrigues me. I have an older van that I have installed 2 100Ah lithium batteries for the coach. It has an old sure power isolater and an emergency solenoid switch. Are you saying I could replace them with the Cyrix, because of the lower Ah? Worried about taxing my 130 amp alternator. Thanks!

      @@johnroyer3191 It's possible/probable the *existing* setup will work. I have data on 10 installs where 200Ah of LFP is direct charged; the average highest current observed is 65.5A at low states of charge, with ~40A being more typical in middling SoC.
      Depending on where the alternator's voltage regulator is sensing battery voltage (after or before the isolator) the current could be lower: I=V/R, and the V would be lower in that case. Maybe a max around 45A.
      If it were my setup I'd:
      1. ensure there was a fuse inline at a current I was comfortable with the alternator seeing
      2. try it out with the bank nearer full charge (high SoC, hence low current acceptance), observing current. If it trips the fuse then the experiment is ended and some other charging method is required. Maybe a 40A DC-DC or something.
      3. if it works, try with the bank at lower and lower SoC to see what maximal current will be.
      Caveat: if the bank is seeing full alternator voltage (ie, battery voltage sensing is done after the isolator) then the LFP would see that full voltage with no way to disconnect it. The lack of disconnect with diode isolators would be less of an issue if the bank is seeing [alternator voltage minus 0.7v].
      A Cyrix-LI would also do the job with no voltage loss but it could be deactivated on demand. It could eliminate the existing emergency relay since that function is built into that device.
      If you do try direct-charging with the existing setup or cyrix please report back with your results for our greater collective understanding.

    I completely disagree - Generators are not reliable, they're loud, and are being outlawed in some states. A high output alternator can work while your main engine is idling. A Balmar XT-250 will output over 100 Amps(at dwell temperature) with your main engine at idle. - I do have to disclose that I work at Balmar :)

      @@EXPLORISTlife ... confused. If solar and alternator are both attached to a bank...... they charge... they dont care about each other. Only about voltage of bank. Granted one might auto shut down do to what it reads voltage at.
      example... AM solar FAQ statement
      "Do I have to shut off the charge controller when I connect to shore power?
      You can have multiple sources charging the same battery bank at the same time. Whether it is shore power, an alternator, a generator, solar panels, etc., it doesn’t matter. Connect them all. Run them all at the same time. No additional protections or switching of any sort are necessary. Chargers of all types are protected against reverse current flows and base their output on the voltage of the battery bank they are charging. When a battery is getting charged by any source, it’s voltage will go up proportional to the amount of current being fed onto that battery. In some situations where you have a particularly strong charging source, like an alternator or shore power, the high current fed onto batteries will drive the battery voltage up to the point that the solar charge controller thinks the battery is full. When that happens, the solar charge controller will temporarily stop charging until the voltage returns to a lower level."

    • @EXPLORISTlife
      @EXPLORISTlife  ปีที่แล้ว

      That's correct. They can all be connected at the same time, but they will not 'combine' their charging amperages. This is a feature that should be available in the next version of the Victrion Orion, but currently, one will overpower the other and the 'weaker' of the two will gate back as that FAQ describes.

      Actually yes for most brands that have a dc-dc charger they will do a mix of solar and alternator when both are available and just one at a higher rate when it’s the only one available.
      Also most people setup seperate dc-dc and solar inputs which means they do combine their charging capacities

      "takes forever to charge". The question is this: is it faster to charge from *solar alone* or from the *same solar + alternator* ? It's not like we have to choose one or the other.

    My vans 210a alternator and 140a CTEK system kept my 300a lithium so charged up I had to fit an inline switch to the ignition signal to fool it into thinking the van was not running just so I could cycle the battery properly.
    I cook with an induction hob and air fryer and I have an immersion element as a secondary water heater and I still can't use all of the electricity the van alone generates.
