WTXCal. I am lucky you are such a knowledgeable and patient man. A 100Ah lithium pack would cost $620, and that’s without the monitors and other stuff. I rarely burn propane to cook, it’s almost always free from the sun–no cook meal at lunch and microwave dinner. During the highest sun I plugged in my small shop vacuum to give the inverter a good load and see what kind of peak wattage the panels could provide. This translates into higher efficiency which means a shorter generator run time during those times when you find it necessary to recharge quickly. Once the sun went down at 4:45 PM I used two LED lights, my 17” laptop, a portable tabletop radio, and MiFi internet hotspot most of the evening, I also watched 1.5 hours of TV on my 32” LCD screen. The fuse holder should be the same size as the cable. But that means you have to have enough room on your roof for a third panel, which dandelion didn’t have, or she has to carry and store a third panel and take it in and out every time she drives. http://www.technomadia.com/lithium/. There are many nice monitors on the market and I have my eye on a few but they are up in the 200 dollar range so for the time being I’ll have to rely on my own cobbled together system. This glass mat also provides pockets that assist in the recombination of hydrogen and oxygen gasses (that are generated during charging) back into water. Copyright © 2020 Love Your RV! Internet has tables, Bob, Billy, you need a 40 amp controller for that. Billy, I’m confused, here is the Renogy 200 watt kit for $340 Just be sure you don’t let the combined total be too many watts for the controller. There is no addtional cost to you.

I’ve learned a lot. They decided to see how the two systems compared since they were both in the same climatic conditions. CHARGE CONTROLLER INSTALLATION 1. If you are in the USA I have no explanation, it’s a mystery to me. Call it seller’s remorse, but I sure missed mine when it was gone. I don’t worry about lead acid off-gassing so I have them in my van. I know at least a dozen people who own Renogy solar panels or complete systems and they are all totally satisfied with them. Renogy 400W 12V Solar Starter Kit features four 100W 12V Solar Panel, one 30 amp PWM Charge Controller, one 20 ft. http://www.technomadia.com/2015/02/living-the-lithium-lifestyle-3-5-year-lithium-rv-battery-update/ If I watch any TV, maybe 40.

Very few people will benefit from them this early in their lifetime. Hi Bob. You can see they suggest combining the panels in series. After reading the article and literally all the comments I am convinced that MPPT is far superior. These batteries have very thick positive plates and belong in the true Deep Cycle class. This kit could provide a 20 watt device with power, along with some overhead to recharge batteries after a cloudy day or two, 24 hours a day in the winter in my area (3.7 peak solar hours). The more ah in your battery bank, the better during storms and winter. The cables to the batter will be 1 ft long. Your email address will not be published. My Cougar trailer has a EDPM rubber membrane type roof so I decide on Dicor brand Lap Sealant and Eternabond Tape. Here’s a link to a report: Solar is nice and all, but you never know when something might blot out the sun. Now, lithium is supposed to last longer than lead batteries, so the extra cost would be amortized. The includes Compact Design or Black Frame 100W Solar Panels are not only sleek in size and weight, but are made of high efficiency monocrystalline solar cells.

DBM Solar recently posted…Google’s Project Sunroof is Mapping the Planet’s Solar Potential, How would you add portable panels to an existing rooftop system? Or, if you have a 2000, you might be able to use an electric chainsaw. You decide how large your system is by how many panels you buy. The battery covers allow the ends to run outside about six inches, where the quick releases make hooking up the solar panels a matter of click and go. It’s been a year or two since I used the generator for myself, I’m just carrying it to loan to friends. connections of connectors on the other end. in today's video we get to watch my friend Brooke and Miriam install a Renogy 100 Watt Solar kit on their friends Allie's van. foofoodog, I basically agree.

Bob. Jesse, I almost always recommend wiring the panels in parallel because it’s simpler and most people don’t need the advantage series has to offer. It has advantages but it also is very expensive and has a very steep learning curve. First I cleaned the area really well and under each mount point adding some Eternabond tape as a base. * They are so expensive that if you do mess it up the first time (which is very likely) you could really be hurt financially. See model 2.8.2. Saving energy is a good thing. They also hold up better and at a higher voltage when heavy loads are powered by them. I recommend 6 volts because you know for certain they are a true deep cycle. They need to be charged at a very high rate that your solar panels probably can’t give them, so they wouldn’t be my first choice. for 1.5 hrs. The combination of tilting and tracking the sun with your panels will give you a lot more power into your battery at the end of the day. I have not yet internalized volts and amps (how one calculates them), but I’m not too worried about that at the moment. Literally the first common sense, get to the point no mumbo jumbo know-how information I have found on the web. Bob, Bob, I agree with you 100%! This worked out really well as I was able to make the run from the solar panels right to the battery area using only about 16 feet of  the 10 gauge wire Renogy included in the kit.

I recommend Trojan batteries, I assume they are in Canada. Bob. Designed to keep. Brian and I are in study mode (AKA Dummy Mode) concerning photovoltaics, and one of the many things I don’t yet understand is how one switches from relying exclusively on solar power to using 30 amp RV-site power, which we’ll need to do when recording. I look forward to putting them to a real test on my usual 4 month jaunt up into the Rockies this summer. I re-posted this link. Bob, I like the idea Dandelion is using with the extension cord.

I AM wondering whether or not it’s possible to use both solar AND a standard 30 amp RV hookup concurrently. Don’t you also need an inverter so it converts 12V to 120V? First thing to do when you start the installation is to decide where you are going to mount the controller. I’ll lose some potential power in the winters low sun versus a tilting system but can always add more panels to make up for it. Bob, I think you’ll be really pleased with them, they are great units! You’ll always get more amps into your battery with a MPPT controller and you can also use a smaller wire from the panel because of the higher voltage in series.

Use these links and I'll make a small percentage and it will cost you nothing: But what if they bring back the carrier pigeons? Nearly all 12 volt panels are actually 18 volt or higher, with a PWM controller it just steps the amp downs and then throws away the amps–they never get in the battery. I’ll also talk about connecting your panels in series instead of parallel  to reduce the voltage drop over a distance. Pterodactyls! Lithium may not be living up to it’s promises. Sorry to clarify … it’s the solar panel built for 12v? The rule of thumb that we use here would be “Continuous Watts / Battery Voltage times 1.25, for example a typical 1000W 12V inverter draws up around 83 continuous amps and we would add the 25% safety factor which comes out to 105 Amps, so we would recommend a 150A fuse.This is a brief introduction and summary for fusing your system.
