Generators are great, but they require fuel, consumables (oil, filters, parts), and "attention" to keep running. Fuel requires power to get from where it is "made" to you. Once the power goes out over a large area that power is going to go away. The loss of that power is also going to make it difficult for you to get the consumables, as well as give the generator any "attention" as you will be fighting for your lives just to survive.

Solar. Battery. And keep the loads as well as the rest of your life as simple as possible.

Good grief suddenly there are ads on the tv stating that no on one is thinking about power or outages. This is running every few minutes. They’re glorifying black outs.

Spare me you’re holier than though I don’t own or watch a tv crap, nobody cares.
I have not seen them, but believe you me, I think about it a whole lot. My husband was a lineman for years and now is the purchasing agent for a power company (small). 2 weekends ago, a transformer went out at a big manufacturing plant here in town, and he had to go get the crane ordered etc to reset it. (Yes, he still does that stuff, even though it technically is his assistant's job-he's OCD) He made the comment that he hoped that they didn't need another one anytime soon because the lead time was 40 weeks for that one. He has been telling the engineers and powers that be that if they think they are going to need xyz, they need to tell him NOW, due to lead times. He tried to order a couple of transformers (pad mounts) for backup, and was told that since they had one that had just been swapped out, it could be used as backup... Hurricane season has not been terrible as far as seasons go (not downplaying the damages there have been), and neither has our storm season, but we still have fall to get thru here in the SE and lastnight's storms show what a booger those can be, and then you have the winter storms coming out west and up north. Supplies are gonna get tight, no matter what line of goods you are looking at.

That was our 2nd year in Florida. LOL. I suppose it isn't funny because that was the first nail in the coffin of the citrus industry in this state. My Dad had just come back in '75 from being TDY a year in Greenland. He said we were moving to Florida and he was never ever seeing another snowflake. ROFL
The winter before I was in training at Camp Greely in Alaska. I was much warmer that winter and I had to sleep with my food to eat breakfast in the morning. We did not get much breakfast in Florida. By then we were down to one Sea Ration a day.

That was my point.

Even if too old to cut, he should be able to gather as long as he is still ambulatory.
In my area, not much would be gained from gathering. Mostly twigs.

I am well past 70 and can still run a big chainsaw and split firewood but it is rapidly becoming more difficult.

Bending over and straightening up repeatedly creates the most problems for me.

It varies a lot with the individual

Yeah, one can't heat and cook with a few small limbs and twigs. We rely only on wood for our heat during the winter, and I have a wood cook stove that is also used. It takes a lot of firewood to keep those going.

Right now, Cary is well able to cut, haul, split, and stack all that we need. He's only in his 60's, so he still has a good many years left, God willing. It never hurts to plan for the future, though.

LOL doesn't know big wood from brush. LOL

I will admit that gathering squaw wood is good for quick fires to cook like stir fry foods but that is where it ends.

And once you use all the squaw wood in an area, you're also done until another squall comes through.

Yes, Ma'am. It's pretty simple. I'm sure you're familiar with standard outdoor lighting fixtures, right? They're the type that usually have two bulb receptacles. All you have to do is connect a red automotive wire - which will be the positive wire - to the center conductor on the fixture. That's the little "button" at the bottom and center of the fixture. Connect a black wire to the metal "screw" part of the receptacle. That's the negative wire. The red wire will go to the positive terminal on a battery and the black wire will go to the negative terminal. Simple, eh?

Clear as mud.

:worth:

Even easier than dealing with all of the wiring, they sell these already made (although you could make your own quickly using two alligator clips and an old 2 prong extension cord...).

Thread drift, but it’s Interesting how many of us had dad who were stationed in Greenland. Mine was too, but says he still can’t talk about some of it. ;). Iirc, my dad did two tdys up there. He does tell us about life in the ice.

Yeah. Instead of a "can" or barrel being used, they use concrete blocks or adobe or similar. The stove then gives off heat at night when it can get really chilly at high elevations, even in places like Mexico and Guatemala.

Yeah, my father was part of some of those "training exercises" in the california desert, Greenland, and Honduras. He has PTSD as a result. I do know that when he was stationed in Honduras they would get grenades tossed over the balcony of their housing unit.

I respectfully disagree. We have solar, and I used to use a modified sine wave inverter for power. It made motors "buzz" while running. I once ran the well pump from it, and the well pump coincidentally died a few days later. Cost me $1750 to replace. Modified square waves cause motor windings to vibrate to the degree that their wire's insulation can become compromised and short out. And motors definitely run hotter from it. OK for resistance heating, incandescent light bulbs, and non-inductive loads. I now use a 24 volt Outback Power pure sine wave inverter/charger that I paid around $1700 seven years ago. If I need 240 volts AC, I have a (heavy) 120 volt to 240 volt transformer that does the job (purchased from eBay). In the northern states, it is absolutely a fact that you will not be able to reliably keep your batteries charged over winter, not from snow blockage, but from generally dim sunlight conditions. We have a Honda 12 Kilowatt generator that we run from our 500 gallon propane tank able to keep the batteries charged in such a case. The inverter is able to also charge the batteries from the grid or generator, a major plus. You want an inverter that uses a 24 volt input if you ever plan to go above one kilowatt output, or the battery to inverter cables will have to be ridiculously thick (as in at least 000 gauge or more). So buy a 24 volt inverter/charger to keep your future expansion options open.

I have a book on how to make the built-in ones. They are adobe, concrete, or masonry, and much larger than your standard coffee/soup can camping version. They still take small sticks, burn very efficiently, and produce little smoke. Similar to the Russian is some respects (you can sit/sleep on them). Also very good looking.

My husband is out of the wood cutting business, but I can do it if I have to. However, at this point we just buy the wood cut and split. It makes life a little easier.

There's probably people around we could buy our firewood from, but we haven't had a reason to look, yet. I would think that even buying firewood would still be cheaper than propane, natural gas, or electricity to heat and cook with.

Or better yet, work towards switching it to Wood Gasification and watch both Newsom's and Greta's head explode from afar...

I have really looked into this (check out the drive on wood forum) and the unsolved problem is that carburetors clog from tar after a year at best. If you are skilled at rebuilding carbs (I'm not) then no problem.

Was talking to the man who fills our propane tanks up. We decided to fill up in the summer to save money. Good thing we did, we paid 1.33 gallon and now its up over 2,00 a gallon and its going up Corn drying is going to cost us dear this year.

It’s the inverter’s carrier wave that causes the laminations in the rotor and the windings to whine. If it is not set properly, which I do not know if can be done on home inverter systems, it can burn out motors. New and improved 3phase industrial based inverters do have the capability to change the carrier frequency in their programming. This change make a significant reduction in motor noise, let the motor run cooler, and more efficiently.

Understand... my point was not that three phase inverters could be used in a home style setting. My point was it’s the inverter’s carrier wave frequency that causes the damage and noise to motor loads.

As stated I do not know IF home inverter system inverters have the programming ability to change the carrier. My only point in using three phase inverters as an example was that it was just that; an example.

I am not familiar enough with home inverter systems to comment as to whether or not the end user can make those kind of adjustments or if it’s even possible.

I would suggest that if you anticipate using devices that are line frequency sensitive that you check out the inverter very closely for it's ability to be adjustable and have good frequency stability. I have the Magnum inverter shown above in a solar system, and it's output frequency is NOT adjustable. I think for the most part this doesn't matter, as most appliances and common electrical stuff are designed to accommodate 50-60 Hz (US and the world) frequency rate. That said, I'd be happy to sell a nice clock radio cheap.....

I am not writing about having the ability of altering home inverter system’s output frequency which, in the case of the US, is a fixed 60hz output. European AC systems use 50hz.

What I am writing of is the ‘carrier’ frequency of the inverter output. It has nothing to do with the 60hz output waveform of the inverter. It has everything to do with the transmissibility of said 60hz waveform.

As stated previously the carrier frequency, if set too low or too high, will cause motor loads to whine and the load to not perform or cause motor losses which will affect the motor’s ability to perform its job efficiently.

I have not ever said three phase equipment such as industrial variable frequency inverters can be used in a home inverter system nor have I stated anything about varying the output frequency (60hz) of any home inverter system.

It’s all about the carrier frequency, nothing more.

VFD Carrier frequency

Carrier frequency is the frequency at which the output transistors are switched. In the mid 1980's when I got into the business, the power transistors were Darlingtons, fired by injecting a current on the base that was a percentage of the current carried by the collector and emitter. They could be switched only at around 1kHz or below. This made the motors "sing" - very annoying if they're running a pump or fan in an office building. There was a lot of demand for quieter motors.

By the late 80's the Insulated Gate Bipolar Transistor (IGBT) - a high-power field-effect transistor - was brought to market. This allowed inverters to switch at 5-10kHz (though most didn't switch that fast). Faster transistor switching caused the audible noise created by the output waveform to shift up above human hearing (and/or reduced the amplitude of the motor noise by an order of magnitude or better.)

IGBT's gave multiple benefits to VFD manufacturers: Being a field-effect transistor, the circuitry required to drive the base of the transistor was made much simpler, since large currents no longer needed to be injected on the base - just a voltage. This made the variable frequency drives more efficient - less parasitic power loss, much smaller power supplies. Also, because a fault current on the output of the VFD could be interrupted much better with a field-effect transistor, overall drive reliability improved greatly. Motor torque characteristics were improved because the output waveform simulated a sine wave better. And, of course, the motors were much quieter.

Unfortunately the very fast switching characteristics of the IGBT caused other problems - namely they punched holes in motor windings. VFD reliability was great. Motor reliability, not so much. The problem was exacerbated by long lead lengths between VFDand motor.

A lot of finger-pointing went on for a couple of years until the wire manufacturers came out with "inverter duty" cable, and motor manufacturers with "inverter duty" motors that could withstand the very fast switching. To my knowledge, you cannot buy a low-voltage (690V or below) VFD today that has anything but IGBTs in its inverter section.

If you want a noisy motor, turn your VFD carrier frequency down to 1kHz or below. It'll still sing.

Glad we live down here where it's mostly warm ( thinking about last year). Just had our tanks filled, 400 gallons of LPG that will last us well into next summer. $2.70 a gallon right now, the lady says the price is climbing like a rocket. I know it was $1.50 a few weeks ago when I filled the RV.

We get by on little electricity here. Have two generators, a 2K and a 3.5K, both inverter sets. So far, after hurricanes, we've only used the 2K watt to keep a refrigerator, two freezers, a window air conditioner at night, and various little items charged. That little jewel will run 9+ hours on a gallon of gasoline. I've got 60 gallons stored, just replaced after putting the old in Suburban and pickup.

I do have 400 watts of solar and a 500 watt TSW inverter and 4- 6v golf cart batteries, but haven't had occasion to use them, except with the RV. 'T'was always cloudy after a 'cane.

Did you not hear about the propane shortage? Several farmers I'm following on YouTube are talking about the propane shortage, it's pretty bad right now, as it's used for drying grain after harvest.
It's bad enough that the ethanol plant will dry the corn for free this year
