If you are new to this, I recommend starting with the “About our Boondocking Life” page to see how this all started. I am not a “blogger” who constantly posts. This blog is intended to educate, not to be used as a discussion forum. Last, if you feel that I have helped you to save your money, take a look at my page: The Money Question.
Tapping the circle to the left will open the comments that have been left if you are interested.
The following are links to places I recommend that you look for more information. Insert the usual warning here. You must temper everything you find with common sense. There is both good and bad everywhere you look and I cannot keep up with everything anybody else says. My opinions follow. Some may not agree, but I speak from experience, not what somebody else told me. If a link doesn’t work, just do a Google search. These things are finicky. I DO NOT APPROVE ANY ADVERTISING THAT GOOGLE ATTACHES TO THIS BLOG. THEY WANT $30 PER YEAR TO BLOCK ADS.
http://cuernoverdesolar.wordpress.com/ A friend / former customer who also does not own a generator
http://kingsvista.wordpress.com/ An interesting blog about off grid RV life by another friend / former customer.
http://www.jackdanmayer.com/ Some good solar & RV info from the big rig side of the RV life.
http://bogartengineering.com/ Manufacturer of the Trimetric, the only battery monitor to buy.
http://www.magnumenergy.com/ The best alternative energy inverter manufacturer and located here in the US.
http://www.midnitesolar.com/ A high quality, innovative US manufacturer who is cornering the market for very high quality alternative energy distribution equipment and maker of the best solar charge controller available as of 2013.
http://www.morningstarcorp.com/ The manufacturer of the widest variety and the best inexpensive charge controllers on the planet. A company that is dedicated to making things that actually work. Very unusual today.
https://www.crownbattery.com/ I believe these to be the best after buying them for two off grid homes and installing in several RV’s These people have the alternative energy market in their sites.
http://www.trojanbattery.com/ Probably the most respected, I used to think they were the best. No longer. Their web site still does have the best charging information. Remember, batteries are batteries when it comes to charging needs. I know that I say to listen to the battery manufacturer but some of those folks do not understand charging with limited amps & time, so some info you will get is wrong. For flooded batteries listen to Trojan, for AGM’s, Life Line.
http://backwoodssolar.com/ These folks have a catalog available that has a LOT of good information in it. Their web site also has diagrams, you just need to look hard to find them. Great service & friendly advice.
IF YOU WANT TO ASK QUESTIONS, THIS IS NOT THE PLACE TO DO SO. You can email me after you have read the RV Battery Charging Puzzle, where my email address is included.
THIS IS THE SHOP OF ONE SOLAR GUY WHO CAN BE TRUSTED. (look at the Fall 2012 page for newer info.)
This little system powers construction tools, heat shrink gun, you name it. The batteries in that shed were 10 years old when the photo was taken and have since been retired. They were charged daily at 14.8V with temperature regulation just like Trojan recommends. The batteries in there now are six year old T105′s that were free.
Most of you are probably looking for the “RV Battery Charging Puzzle”. This is also good basic education for anyone who wants to go off grid in a cabin or small home. My email address is shown there, but please don’t contact me with questions unless you have read the Puzzle. You don’t have to read my rants under “The History”, but it explains how I ended up where I am today and gives some examples of recent solar system evaluations that demonstrate very well just how little has changed. There are now a couple of RV Solar dealers doing working systems but I will not recommend anybody yet. Both of those companies will sell you nothing but MPPT, even when it does not make monetary sense on small RV systems. MPPT does make sense on large systems only when you spend enough to get something like a Morningstar Tristar MPPT or MidNite Classic controller. These dealers’ advertising make it very clear that they are not “low budget” installers. Many people think that when they see advertising that shows huge over built systems on the roofs of RV’s they are seeing proof that the company knows what they are doing. I believe that it proves just the opposite and that it is a bold statement about their real mission statement (to generate as much profit as they can). You also need to think about the power line that goes into the building. If they knew how to make solar power work, there would be a modestly sized solar array powering that building. They buy solar panels cheaper than you can and the same tax break is available to them. There is one guy in Quartzsite who put grid tied solar on his building, but that does not show that he knows how to charge batteries. He does not. The statement about having to add water every other day if you follow Trojan’s voltage recommendation came from that place. His actions speak louder than words to me. I met a new dealer in 2011 who lives off grid and yet he sells junk flush mount RV charge controllers at his booth. Again proving that he either doesn’t know or doesn’t care.
Many of the dealers also still tend to fall down on the job on things that I find unforgivable, like the missing wiring protection on one system that I reported on, the constant overloading of controllers, the continuing refusal to install big enough wiring for MPPT to really have a chance at working and the denial of how important temperature compensation is. I’ll post it here first if this ever changes. You should note that Morningstar believes so much in the value of temperature compensation that it is included at no extra cost on all of their small RV controllers. They also include the remote temperature probe in the box when you buy their new Tristar MPPT controller. So does MidNite. Plus, they also include the USB cable for downloading updates.
I constantly see people attributing statements to me that I never made. For instance, I have never said that nobody needs a generator and I never told people to sell their generator. I did say that WE don’t need one. Our back-up charger is our noisy Ford 7.3L truck & booster cables. It has only been used four times in over six years and one of those times was because of a failed solar panel. As of fall 2013 we still do not have a generator on the property where we are building.
