RE: RV Batteries - Lithium as Option

After having my service guy look things over, he came up with the idea that the sliding tray the batteries were on was taking up a lot of space, and that by removing it, I could not only fit the batteries I wanted in the now empty space, I could probably get 10 flooded batteries in there... a terrible waste of space, he said... but, it appears the best choice for me are the Battle Born Lithiums, and have decided to go with 4-100Ah that should fit nicely, with the tray removed...

Battle Born Lithium

In my research to learn more about Lithium batteries, and replacing the flooded 6V's in my rig, I just discovered Battle Born Lithium Batteries (Reno, NV) will soon be introducing a 250Ah battery, due sometime later Fall, or early Winter... no pricing yet...

RE: solar charger

Ditto on Solar... determine how many Amps you typically use in a day... 100W Solar will generate peak of about 5.2A... so... rough estimate, if you burn through, say 25A/day, you might consider up to 500W solar.

RE: AGM upgrade

Might want to consider a change to Lithium batteries... expensive, but, long term costs re generally lower, and features and advantages may outweigh initial cost. LifeBlue has a version which can be charged down to -4 degrees - typically, Li batteries can't be recharged below 32 degrees...

RE: RV Batteries - Lithium as Option

First, the dilemma, then the answer... My dilemma came about regarding dimensions. Initially, it appeared I would have trouble fitting them in, because the dimensions of the Li were larger than the battery tray - too long by about 3". Even with the 100Ah, I could only get 3 in, length-wise front-to-back, to replace my 4 flooded jars. That meant removing the tray, having it modified to fit the new Li's. Then I remembered something... these Li's can pretty much be positioned any way one chooses, absent upside down, so I measured the battery compartment, and discovered I have about 20 1/2 inches of height open to me, and at 19.1/16", standing both of the 200Ah I wanted on end, wired in parallel, they would fit just fine, as long as they were strapped down and secured to the tray... I would then have 400Ah at the core of the system. Does anyone see an issue with this approach?

RE: Okay How many RV'ers here use CB-Radio's?

Back in the 70's, I used to have an SBE Sideband number in the car, and a Siltronix 1011-D at home. The Siltronix was a HAM radio I had modified to work on CB frequencies... it had a VFO (Variable Frequency Oscillator) and I used a D-104 mic. For a while there, I enjoyed meeting people, chatting, etc., although, of course, once kids got onto the channel, it soon became messy... Since I, and many of my friends, had VFO's, when there were kids messing up the channel, we'd go in between channels (where a click, click channel changer on a typical CB was 10 KC's apart, fixed) and after a few minutes of normal conversation, the kids would leave, because they couldn't find the channel we were on to complain!

RE: Replacing current 30A with MPPT controller - make sense?

Let me be clear here. My original post was entitled "REPLACING current 30 A with MPPT"... there was never any desire, plan, or curiosity about having BOTH controllers functional in tandem... Great information from this exchange, thank you all... I'm all ears... or rather, eyes...

RE: Replacing current 30A with MPPT controller - make sense?

If each panel has the capacity to provide 8.7 amps of charge, I've read that without the MPPT controller, I could lose up to 30% of those amps in the process, and thus, it would seem to take longer for the batteries to recharge, or to maintain their charge. In times of limited sunlight, it seemed wise to make the best use of the tools available, and it appeared such a controller would improve the charging process. Q 1. I doubt you are losing anywhere near 30% with PWM and your present panels, unless wires are really thin - both before and after controller. Need more details on wiring. Q 2. If limited sunshine affects your charging, you need more panels. Not necessarily a different controller. First you need to check whether your charging is really poor. My thinking, too... first to get installed is the Victron-712 Voltmeter. I can then more accurately observe the status of current flooded batteries - which, IMO, are due for replacement anyway. A Victron 100 A controller would reveal if additional solar would be needed, and assuming this is so, a controller with greater capacity is necessary to handle the additional 340-600 W panels, 24 V, needed on the roof, taking into account the wiring gauge and distance between all components. Existing panels are 12V.

RE: Replacing current 30A with MPPT controller - make sense?

Are you panels wired in series or parallel or a combination of the two? What gauge and length is the wire between your panels and controller? Are you willing to rewire the system if that is what is needed to improve the performance? Panels are currently wired in parallel... my installer tells me that with an anticipated change to an MPPT controller (Victron 100 A), a new Victron voltmeter install (Victron 712), Lithium batteries, and another 300-600 W solar on top (24V), connecting panels in series should be considered...

RE: Inverter - Charger - Leave well enough alone?

Mr Canoli, I am glad to see that your head is on straight. I think the only thing that you missed, is that you did not do your power calculations on a spread sheet. This matters because when you make small mistakes, they are very easy to see and correct. Your list of components is a very good start. Even with 400AHr of LiFePo, you will still be limited for running A/C. For the list as I read it, 200AHr will get you along for most cases. In the past, I have done a number of conversions of racing boats to performance cruisers. Racing boats have little for creature comfort (including house electrics) and other accommodations that differentiates them from (anything) cruiser that has these features. The first part of the planning is the plumbing and electrics because the wood work can be fit around that stuff. Many would like to be able to run the main cabin A/C on the house bank. These are tiny units because they are water cooled and it still doesn't happen. I strongly suggest that your eliminate that line from your program. Unless someone gifts you the still viable battery bank from a Tesla. Matt Actually, Matt, not only is the AC offne list, it really was never on it.... I wanted enough power to run it, but fully understand and appreciate the energy required to do so. You're right that I didn't work a spreadsheet for power calcs, I'll remedy that soon... thanks!

RE: Inverter - Charger - Leave well enough alone?

I think you may be a bit confused about electrical units here, and what they're measuring. I hope this doesn't come across as overly pedantic; I'm writing it in hopes of helping you understand, nothing more. You wrote that you figured your electrical use per day was 2000 watts. Watts are a unit of power, similar to horsepower; it's a rate of doing useful stuff. I suspect you probably meant that you require 2000 watt-hours per day, a unit of energy, but I'm not sure on that. 2 kWh seems rather on the high side to me particularly if you don't have a residential fridge, but you know your needs and so forth better than I do. 18 Amps is a measure of current, not directly equivalent to either power or energy. In RVs they do sometimes get used that way with the (often unstated) assumption that the voltage is known, either 12V for DC loads or 120V for AC loads. 18A at 12V is quite a different power level than 18A at 120V: around 200W for the first, and 2000W for the second. Amp-hours, a unit of electrical charge, may be what you're thinking of for your 18A. 18 Ah at 12V is equivalent to approximately 200 Wh; 180 Ah at 12V is about 2000 Wh. Thus, you'd need maybe 200 Ah of battery capacity to go 24 hours without solar charging or generator use, etc. If your present batteries are 6V batteries, that's about the capacity of your present battery bank. Note that it's not practical to use solar "only" without tapping into the battery bank, unless you only use power when the sun is shining. What I think you're aiming for, and it's a good plan, is to have sufficient solar capability that you can produce at least as much energy per day, on average, than you consume; if that's true, then you can operate indefinitely without needing a generator or shore power connection. My initial impression is that you'd be better off investing in more battery storage than in additional solar panels. It sounds like you have enough, or close to enough, solar power to meet your daily electrical needs, but not much storage to buffer it between when it's available and when it's needed, particularly if you have a day or two of cloudy or rainy weather. For most people, it's not at all practical to run an air conditioner off of solar power. If you wish to do so, it would make a lot of sense to spend some effort in better insulating the RV and probably in replacing the standard RV air conditioner with a more efficient model, perhaps a mini-split unit. Thanks, Drew, as I said, hard to wrap my head round this stuff.. yes, the plan was to produce at least as much as I consumed. The Li batteries I'm considering amount to 400 Ah, so it appears I'd have sufficient capacity. I'm aware that the AC would consume a lot of power, and thus, isn't practical without a generator or shore power. It wasn't running the AC, it was having the power to do it, but maybe that's unnecessary. I MIGHT be able to put two 300Ah Lithiums in the tray, but I don't want to. By the time I'm done, I will have invested much more than I needed to in the wrong things, so capping these enhancements makes sense, and in the bigger picture, probably is more than I really need. A better Inverter-converter-charger would make more sense to me.

RE: Inverter - Charger - Leave well enough alone?

“I felt it worth the peace of mind to look at upgrading my system so that I might enjoy a longer stretch dry camping,..” If this comment is regarding electrical power, you are missing the point. An adequate solar system recharges your batteries fully every clear or mostly clear day. If it doesn’t the system is faulty. Isn’t 2000 watts at 12 volts about 165 amp hours? Not 18. yup...

Inverter - Charger - Leave well enough alone?

Here, yet again, I have more questions... you all must be getting a little tired of me with these inquiries, and I very much appreciate the patience of those who've responded to my previous posts. My focus has been on the electrical side of things lately, and so, as I learn, I keep checking things off the list... One that remains is whether or not I ought to consider changing out my Inverter to something more... capable. First, the components: I currently have flooded battery bank which I'm planning to change to Lithium - two @ 200Ah. These batteries are between 3-4 years old, and likely require replacement soon. Awaiting install of Victron 712 meter, and a Victron Smart Solar 100A MPPT Controller. Considering adding 340 W Solar to existing 480 W on roof, plus 120 W portable panel. Existing Inverter is 2000W Modified Sine. Current controller is PWM 30A. Since my plans are to spend more time boondocking, I felt it worth the peace of mind to look at upgrading my system so that I might enjoy a longer stretch dry camping, when I choose to do so. Strictly a novice here, hard to wrap my head around electrical theory and practice, so, I've been on a mission to learn, and research, opportunities to upgrade my system where it makes good sense to do so. Question is, I'm not knowledgeable enough to know if it DOES make sense. First, I'm considering adding another 170W panel to the roof, and adding another portable panel of up to 200W. My objective here is to be able to generate enough solar to avoid tapping into the battery bank. While it may come to pass that I would run the AC, I'm not convinced I need to add enough solar to do so. After all, I do have a generator. I HAVE been wondering if it would be prudent to change my Inverter to a 3000 W or 5000 W Inverter to address the potential that I might want to run the AC off grid. Prices for this seem pretty reasonable - most between $280 - $500. As I'm of the opinion that it's better to have it and not need it than the other way around, I'm willing to absorb the cost if it will bring me closer to my goal. At most, my wattage needs appear to pencil out to around 2000 W/day. That comes to about 166 amps. AC not factored into this. Am I on the right path here? Am I understanding enough to have asked an informed question? What am I missing, or not considering?

MH Manufacturer of Choice - Poll

I did a lot of research before buying my MH... I was curious, however, about what other people bought and why, and what their experience has been. I realize much of this is subjective, and that many have the "best" on the road... if you're happy, you're happy, and good on ya! What would you list as the top / best / favorite manufacturer, and please name the type of RV you have (i.e., MH, Towable, etc.)?

RE: 75 Speed Limit - How Fast

Thanks for the responses. When we travel to/from Florida, we seemed to settle in around 63mph. Wasn't certain how the big rigs felt about RVs doing 17mph under the speed limit.....but that is where we are comfortable and what we will do. Wise choice IMHO... you ain't drivin' a Ferrari! It's a road worthy brick!

RE: Solar - Permanent mount or portable?

I've see theft at a campground. An entire cooler of booze and some other items. Fortunately, the thieves were found. Unfortunately for them, it wasn't by the police. My future trips will include my trail camera and a portable solar charged motion senor spot light. I like this idea... better yet, design one with a suction cup attachment, battery operated. Can stick it anywhere....

RE: Solar - Permanent mount or portable?

Interesting... I'd never given thought to the potential for theft... is this more common than not? No more likely to be taken than a Coleman lantern I've always left out when away from the campsite. In all the years I've been camping and backpacking, and the few years I've enjoyed the RV lifestyle, I've never heard anyone speak of, much less experience, theft, but I'm sure it's not unheard of. I've cleaned up my camp, neatened it up, but always left stuff out, with nary a problem. RVr's who have a stand-alone sat dish always leave their stuff out, far as I can tell... never heard about any issues... But, that's no guarantee, and temptation can change a persons nature, enough to see an opportunity and go for it. And here I go, getting pretty far off the subject...

RE: Solar - Permanent mount or portable?

Pianotuna, I can appreciate your caveats, and they are worth considering, but, how often might it rain ? I'm less confident about roof panel's usefulness in the shade when, with 1 or 2 portables, I can easily aim at the sun, should the charging be needed. Yeah, the panels are potentially cumbersome, and storing them could be a challenge, but then, if I can store them safely - one already is conveniently tucked away - I would, I think, have only one more to find space for. This could prompt me to seek out panels of a size where I CAN store it conveniently. It would also be interesting to learn if there's a means of tilting the roof panels from the ground, since climbing on the roof at my age probably isn't the safest approach, but then, securing these panels would seem to require a hands-on approach. Still cogitating this dilemma... As for the batteries, I'm definitely leaning toward two 200Ah Li's, though I have room for the four wet cells that will come out. Others have suggested keeping all batteries at the same size and Ah... What I'm needing more clarity on is the panel voltage, why higher might be better, how it would function with existing panels which operate at lower voltage. Mono vs. polycrystalline is also not clear to me, though a little research will solve that... some of which, by the way, suggests an MPPT Controller north of 80 amps for the panel wattage I envision...
