Just received my kit. 2 100w panels with a 30a pwm controller. Hoping it will recharge my 2 GC2's. I am alone in the trailer and power use is min. Any thoughts?
Wire them in parallel.
Is your PWM charger adjustable for voltage during bulk charge mode? If so, set it for 14.8V in bulk mode.
Mount the Charge controller as close to the batteries as possible, in the closest compartment that won't allow the controller to be exposed of off gassing while charging. 3 to 5 feet of 10 gauge wire from controller to batteries should minimize any voltage loss to 1% or less.
12 ga wire from panels to charge controller should be good for up to 20 amps of solar panel, you are currently at about 11 amps, max.
Perhaps a link to the kit that you bought, so we can see which model charge controller you got? If it's similar to the Amazon version kit, you'll want to scrap that charge controller asap and get something that is voltage adjustable in bulk charge mode to 14.8 to 15.0V for when you want to top charge, which should be daily, especially if you are dry camping for periods over 7 to 10 days in a row.
NinerBikes...February is storm time. Lots of folks go to the coast for that very reason. The state of Washington has a couple of great storm watching sites, too. One of them, just north of Aberdeen, Pacific Beach is primo!!!
Thanks, driving, though, from So CA.
I gave up a long long time ago... what I need to know is that if you go with 30V or more panels, and have a 12V system, and go over about 400 watts to 750 watts in 28 -30V panels, then you want to look at a MPPT controller for charging your batteries.
If you are at or under 360W and have 12V panels, PWM controllers that are usually 1/3 the price of MPPT controllers are what you should be considering, and your 12V panels will most likely be more expensive per watt.
Those are the current Break even sizes in watts for charge controllers currently. YMMV... I am in the portable panel camp, none of this really applies to me except as an exercise. My take on it is that MPPT is poorly understood and poorly marketed as to what slight benefits it might provide in the smaller systems, and break even points when it comes to cost per amp now in solar panel costs, which continue to drop, the price of solar panels, in terms of $ per watt.
39 pages, and jrneyman and others, myself included, still don't understand fully, the actual benefits per $ /ah charge rate for MPPT.
I'd go with a pair of 120W if you roof mount, or you could probably go portable with a 160w and aiming it at the sun a couple of times a day. You need less watts with the portable vs roof mount, because it's pretty much always in alignment with the sun by aiming 3 or 4 x a day, so it's amperage yield will be considerably higher that flat mounted on the roof, it's much more efficient aiming directly at the sun.
Get a good charge controller also that has adjustable input voltage for the bulk charging mode, and set it for 14.8V, that way you'll hopefully charge to 97 to 98 or 99% daily, instead of just 90% State of Charge at 14.4v.
Been there, done that.
Putting 45a into a 215Ah bank, it will remain in bulk until ~80% soc. A 50-80% would take about an hour and a half; voltage slowly rising from about 13v to 14.8v over that time period. Putting 45a into a 430Ah bank, it would remain in bulk until well past 80% soc, voltage slowly rising all the while. The only way to get to 14.8v rather quickly would be to use a very high C-rate, like 75a on a 215Ah bank.
You assume you get 45 amps at daybreak... you don't. Amps ramp up slowly with the sun and often can be at 14.8 before max output is even available.
To really get max, the battery needs to be a bit oversize or you need cloud cover to about 11am. Then with sudden clearing and full sun you will get max power into a low battery.
Hard pressed sometimes to even get down to 50% because each day you are closer to 95% to 98%+. So the 50-80 becomes 68-98 and you hit that 80% fairly quick.
I'd say this is a very good daily goal to have, battery capacity wise and solar panel and charge controller wise. Easy on battery longevity also.
X2. And for those that don't believe it, do your own experiement. Tomorrow on your way to work, count the number of 1500 series trucks that are hauling nothing but air vs the number of 1500 trucks that have something in their bed or on the hitch.
And, I do agree that the economics might not make sense right now with the price per gallon of diesel vs gas, but this is about CAFE ratings for Chrysler and the emotional side of a car purchase for the buyer. For many, it feels a lot better to look at their MPG reading and see 29 vs 20.
Tried that last summer. About 80 trucks in 8 miles on the way home one afternoon. None towing, 2 hauling; washer/dryer & a work site tool box & the other 78 EMPTY. Pretty telling to me how the majority of trucks are being used today.
A sampling in one small 8 mile stretch of road in TN is not telling of the rest of the USA... that would be a gross ASSumption that is far too simplified. I guess you don't have many fleet 1/2 ton Pickups or live near farm country, because it sure is different out here where I live. Where I saw a ton of empty trucks was on I-40 in Amarillo... TX is something else. I guess the oil is cheap there, or image is important.
You request first hand experiences, I furnish what you ask for & your very next post is a rambler explaining how real world experiences don't amount to $HIT!! Very interesting. I suppose we ecodiesel owners will continue to enjoy using our trux like trux while you & your small posse of contrarians turn a blind eye to what's ACTUALLY being done so you can mindlessly continue your vendetta.
I have no problem with you towing what ever you want with your 3.0 liter diesel ecodiesel. There are grades to climb, and then there are grades to climb. Out west, far from where most of your towing experience is, the mountains are tall and the roads are steep.
I tow with a VW TDI V6 3.0 diesel, engine specs are damn close to an eco diesel, but my rig is full time AWD, 8 speed auto, and it weighs 5000 pounds. It's rated for 7700 lbs of towing.
I've considered getting a RAM, but the aerodynamics of it with RAM bragging about a CD of .350 is pretty underwhelming. Plus, I have no problems exceeding the rated 29MPG my Touareg is rated at.
You can see my unloaded driving figures here, along with tow figures for MPG's.
2013 Touareg 3.0L TDI Touareg AWD SUV MPGS and fillups
Ram is rated at 27 to 28 MPG and here are the comparable numbers for the Eco diesel in 2014.
2014RAM ecodiesel Crew cab MPG's
Looks like 27MPG is a damn good number in this truck, or we have a lot of operator error.
...............First hand experiences are preferred. Like straight from the horses mouth.........
I concur a thousand percent, ninerbikers. Unless your a$$ has graced the pilots seat of an ecodiesel & towed or hauled from where do you naysayers draw your "experience" to pronounce where it's capabilities lie? If you want some experiences from "the horses mouth" visit the tow/haul subforum @ our ram1500diesel forum & see where "johnc" spent last summer towing 33' open range 5er; or "mhintze experiences double towing a smaller 5er with his boat or a couple of atvs; "cuzzinolaf's" trip with 4 >200# dudes in the cab, snow mobile in the bed & hooked to a 24' enclosed trailer with another 3 snow machines, gear & trappings for a weekend trip in Wyoming, and on and on and on!! Check it out, many accompanied with pix.
Even this is no guarantee of capabilities... as it depends on each and every application. A Box shaped TT tows like dog sh*t with all the aerodynamic resistance, regardless of weight. Add in if you tow in the Midwest Flats, or the mountains of the North East, or the Rockies and Sierra Nevada mountain ranges with passes over 10,000 feet in elevation and very narrow roads.
Every situation is unique to the owner. Some owners do what I consider tremendously taxing and dumb overload situations with their work trucks, far beyond engineered design limits, because they are cheap, or can't afford the proper tool for the job, or flat out young, dumb and ignorant. Age has a way of weeding the mentally challenged out with annual Darwin Awards.
I used to believe that the American Public was capable of applying some Common Sense, but nowadays, from my POV, common sense isn't so common. Somehow, it's been lost on this newer, younger, up and coming generation... YMMV, these are just my observations.
Another observation I get is folks that post on BB's on outrageous weights or size of things that they have towed, as if it's the equivalent of Internet Bragging Rights. Just because nothing has gone wrong yet does NOT mean that one day, Murphy Law will bite you in the A$$ with huge losses, be it product, truck, or even the ultimate, one's life. Another case of "You can't fix stupid" maybe not, but Darwin can and does, daily. It's when stupid damages innocent peoples lives on our public roads and puts everyone else at risk that I draw the line. If you demonstrate ignorance of limits on the internet, with pictures, with supreme feats, and someone else emulates you and fails, should you be held liable for demonstrating the wrong use of said vehicle for all to see and then have idiots apply a "monkey see, monkey do" mentality? Skill levels in emergency situations vary... some train to react correctly to emergency maneuvers, the majority are ill equipped to handle it correctly.
"Friend of a friend of a cousin of Billy Bob Thornton has towed X cars on a car travel trailer" quotes, are kind of hearsay and been through too many lips and too many ears interpretation before being posted up here. Often called "hearsay evidence" in court, and inadmissable. Certainly not fact.
First hand experiences are preferred. Like straight from the horses mouth.
Personally, I always get a kick out of folks that tell me that their truck "tows like there's nothing back there". If you don't notice that something is back there when towing, either you are ignorant, or not very observant.
I want to know and be reminded constantly when I am towing, that something is "back there" that I have to manage carefully and keep an eye on while driving.
If you want solar to supplement your generator... a good charge controller capable of 30 to 40 amp hours at 14.4V on the generator will get you to 85 or 90% state of charge. A 120 watt portable solar panel will charge at a 6 to 6.6 amp charge rate, and top charge the last 15%, no problem, in 5 hours of good sunlight, even in the winter, like at Q.
PM me for more information, if you are looking for something that will work perfectly for you. I am local... 118 and Balboa.
Dry Weight is 4880. I easily pull it fully loaded with a 2010 F150. All New LED lights inside and out. Batteries Charge much faster while driving and they last 75% longer when dry camping. 4+ days. Many more reasons to look at it. Ken S.
Title is free and clear, or is there a lien on it?
I'll see your good deal, and raise it with this:

Does that come with knee pads too, or just dry, with sand? Ouch!!!!well clearly you're paying for the cable.....
Heck, I'll be looking for the LiFePo battery in that kit too.....
Just talked to a dealer from the frozen north today about the Ram eco diesel and he says they are selling every one they get in, the day it arrives. Also said they have used their own to haul autos on a car hauler to other states and it does an awesome job of towing. Guess it is more than a grocery getter if properly equipped.
I'm calling out the BS card on this statement.
You can say the same thing about 3/4 ton and 1 ton truck also... most of them are used for fleet or work trucks to job sites, not towing TT's or 5th wheels.
So the only towing that matters is a TT or 5er???
Do your own survey while driving around... which trucks are empty and which are being used as trucks??
Build to the market, it's why there are LD and HD trucks.
I live in a county with 10 million people in it, I can assure you I have a larger sample size of trucks on the roads than you do in ID. Rural areas don't sell trucks like city areas, mainly because in the city, we have dump truck or trash pickup services, don't have to haul our trash to the town dump 1x a week ourselves. Farming apps and ranching apps are a whole other matter for primary needs for a truck in a rural area. It all depends on where you live.
The only towing and tow vehicles that matters here on RV Net or Woodall's is indeed vehicles that tow TT's or 5th wheels. This IS an RV Bulletin Board... go to a contractors board if you need a PU truck for that application also, as your primary vehicle.
