Hi Jim,. Hurricane season is just around the corner here in Florida and I am getting ready to buy a backup generator for my home. To be better informed, I have gone back and re-read all the past survivalblog entries on generators, so I am pretty much up to speed on it. My last step is to decide what size generator to buy. One additional piece of information that would be helpful to me, and probably others, is to have an idea of how much wattage it takes to run each of the various typical appliances in a home ranging …

Hi Jim, I just got off the phone with a friend of mine who is considering purchasing a wind turbine to generate electricity for his house. He has a constant breeze at his hilltop location. I told him I didn’t think it would be a good idea because they require a lot of maintenance. Any input would be appreciated. Blessings, – Find 1 JWR Replies: I only recommend wind generators for locales that are both windy and cloudy, and/or that have minimal solar exposure. The cost per watt is so low for photovoltaic (PV) panels these days that they make …

Mr. Rawles: I stumbled across a very cool generation option for very long-term power generation: the Listeroid [“Lister”] generator. Its based on a design that has been in production since about 1930 and as such is dirt simple. Its about as uncomplicated as a diesel engine can be. They run at very low RPM (650-800, no I didn’t forget a zero), are built to be field-serviceable, and have massive flywheels to keep them running smoothly. They’re extremely low-tech and all the bugs have been worked out dozens of years ago. The original Lister company no longer makes them, but various …

James, Anyone considering using a generator and transfer switch should give the following link a look: http://www.generlink.com. It’s an alternative to the most commonly used transfer switches and costs much less. When I called my power company about it they were not familiar with [this brand of switches] but studied the info on it and approved it for installation, they also offered to install it and said they would probably stock them for customers needing back-up power supplies. Regards, – Keith

Note from JWR: Posting all five of the following letters is probably over kill, but I’m doing so to illustrate the power of the collected wisdom represented on this blog!  You folks really know your stuff. Dear James and all concerned, I believe that a safer and more efficient way [than the backfeed rig suggested by Monty is] to power a home via generator is to build a cord much the same way as was previously posted, but instead of having a male plug on both ends, ( which is extremely dangerous and also requires more wire to reach the …

I am a newbie to your blog, also to blogs in general. Awesome job!!! You can power your home with a generator easily and Safely as follows: If your home has a electric dryer and your generator output is less than 30 amps (i.e. Coleman 5000 Watts = 20 amps) Kill your main inbound voltage, main breaker/ disconnect et cetera.Use a male twist lock NEMA plug that fits the outlet from the generator, use appropriate cable (10/3 S.O. cord) size it to the amperage output of the generator (10 AWG  / 30 amps) for short lengths. Use a male dryer …

JWR, I agree that diesel is the way to go for durability, and as most American manufacturing is being quickly offshored that must be a consideration. I decided that the electric start Northstar 6500 diesel (6,500 watts peak) was best for me because the larger sizes such as 10,000 watts and up use considerably more fuel, which can and will become very expensive and scarce. There would also be considerable waste most of the time with a larger size unless I was running the dryer, central air or oven. I do not consider those survival items and there are such …

James: Just me, but I’d call and ask. It sure looks like a generator that runs in the 3600 RPM region. Some use a slightly higher or lower RPM than 3600 but they’re all the same class of service. Northern has a habit of calling non-continuous duty generators a “professional model”, which means absolutely nothing. I’d look around for an electric start 1800 RPM RV version. Also very quiet (to meet the National Park Service regulations), rated for continuous duty and, courtesy of the site, can be fitted for switchable propane or gas. A new 4.5 KW model runs ~$2200 …

Jim Here is a link for an American company from West Virginia: http://www.propane-generators.com/    They make conversion kits for all sizes of generators, etc. to propane and natural gas. (I have yet to order mine, so I was hesitant to share this.) It has been proven that the gases burn much cleaner, and engine life is greatly extended, because the small amount of ash left behind with gasoline that contaminates the oil, etc, is not introduced every time it fires. Carbon build-up is history!  I have been procrastinating on ordering a kit for mine, guess I should get moving. Right …

Jim, Our power here on the North Coast has gone out twice in as many weeks. This time it was out all day Saturday and Sunday, for a total of 40 hours. (Some are still without power, and may be for days.) I intend to be ready for the next one. In a few weeks I plan on purchasing the Northstar 5500 Watt professional. http://www.northerntool.com/webapp/wcs/stores/servlet/ProductDisplay?storeId=6970&productId=448&R=448  That is unless you raise a red flag. But I thought the topic of emergency power might be a good one at this time, since so many are without power. BTW, I might add that …

About batteries: Since 1996 doing my [seasonal] RV living, I’ve been using 16 golf cart batteries: 12 on the back bumper and 4 on the front bumper. They have been adequate for my RV requirements. BTW, beyond the normal stuff, my RV utilizes two networked servers, two workstations, two satellite uplinks as well as three satellite downlinks and my ham radios, all on a 24/7 basis. The inverter is a Trace SW-4024. Then in 1998, I bought the ranch and it, now, uses 16 of the venerable L-16 batteries, purchased from a dealer who wished to rotate his stock. The …

Mr. Rawles In your [list of] resources for solar and off grid contacts you must not have been aware of Kenny G. at www.armadillosolar.net, who is most likely the most respected install team leader in the U.S. and one of the most sought after consultants in the industry. In many cases he has come in to fix systems installed by less than honest installers, particularly in the Texas. In the local area of Austin, Texas I know of none of his customers who are less than enthusiastic about his products and advice. Austin hosts the largest aggregation of residential off …

James: What would be the best choice for batteries for a backup solar system, a marine deep cycle, or golf cart batteries? The marine deep cycle batteries I have looked at are “maintenance free.” This provides no way to add water. Would this be a problem, or do the batteries have to have a way to add water even if they are maintenance free?   Thank you,  – HP JWR Replies: The terms “marine battery ” and “golf cart battery” are used almost interchangeably by some manufacturers,. Both generally refer to deep cycle lead acid batteries with extra thick plates. Technically, a marine battery …

One of the most important steps that you can take toward self-reliance is developing the ability to produce your own electricity. Alternatives for off-grid power include: Photovoltaics Wind Power Micro-Hydro Systems Photovoltaic (“PV“) power generation systems use large panels that generate DC voltage. The most durable panels use monocrystaline solar cells in large arrays in weather-sealed panels with glass covers and metal frames. These are designed to last a lifetime with just minimal care, and do not suffer any significant degradation in output over time. They are made with outputs from 5 to 100 watts. They are easily wired in …
