Worried about power going out? Before you buy a generator . . .

Share

The terrible snow storms this week may have prompted you to consider buying a generator. Before you do, read this . . .

By way of background, Virginia and I have played a key role in building a Community Emergency Response Team (CERT) in our neighborhood. We even have a budget from our Homeowners Association. And a couple of years ago the group agreed to purchase a gas generator to support our emergency planning team.

We originally purchased two, each of which put out 6,000+ running Watts, with 8,000 Starting Watts. On sale, each cost about $800, and was compliant with California environmental laws.

Then reality set in.

First issue: “Pounds per Watt!”

Generator to power a whole house

Portable generator with wheels, handles

Our big generators were deceptive. Their wheels and handlebars make them look portable. After jockeying one of them around it became painfully clear that their weight – as well as their appetite for fuel – was greater than we had foreseen. Also, they have to be started and run for 15 – 20 minutes every month or two or they will require resurrectional service (cost around $100 . . . if WE take it in to the shop).

We returned the unopened generator, and went back to the drawing board.

What had seemed like a good idea at the time turned out poorly. We kept the one generator and plan to use it to power our Command Post in an emergency. There, we’ll need it for lighting and computers and other communications. We’re still debating about purchasing any additional generators.

Second issue: Realistic output. 

You probably know that a portable generators isn’t going to power your home around the clock during an extended power outage.

Generac Standby Generator

Standby, or permanently installed, generator

With careful management, however, an emergency generator can keep a minimum number of appliances operating in order to provide more comfort and convenience during an emergency. And with careful purchasing, you might be able to get what you need for less than $400.

For example, you can apply your power 3-4 times a day for 15-30 minutes to keep your refrigerator/freezer operating. (Exact times depend on the size of your appliance). Charging up electronic devices (laptops, tablets, cell phones, etc.) can be done at the same time since most generators have more than one plug-in socket. But plugging in an appliance that generates a lot of heat – such as a hair dryer or toaster or portable heater – may overload the generator.

Hence, managing run times and appliance combinations is required.

It’s up to you to do some homework by listing the power requirements of your various appliances, combining appliances for a reasonable total power requirement, then finding the smallest unit that will do the job.

Third issue:  What fuel to choose?

Most of the portable generators for sale at your local hardware store or online will be powered by gasoline. So, consider where and how you’ll store the gas you need. Gas is easy to get most of the time (though probably not during an emergency). But gas is messy, is highly flammable, and degrades after 12 months or so.

But what about diesel, you ask? Compared to gasoline, diesel is cheaper, lasts twice as long in storage, is more fuel efficient and less dangerous. But typically you’ll need to install a storage tank to hold it. So, while some generators are set up to burn diesel, they are mostly the larger, permanently installed models that are planned to run for longer periods at higher load.

Some portable generators burn liquid propane and some can burn either propane or gasoline.  Storing propane is easier than storing either gas or diesel; it can be stored in a tank or in cylinders. And propane is the cleanest burning fuel of them all. Naturally, a combo unit (running either gas or propane) is more expensive that a single-fuel generator.

You want to consider all three fuel options.

But, keep in mind that NOT ONE OF THESE MACHINES SHOULD BE RUN INSIDE!  They have specific directions for their use and warnings that should be respected by all users.

Some Guidelines to Help You Make Choices.

These examples come directly from Amazon, where you’ll find literally hundreds of different generators on sale.  We have picked these as having representative prices and positive customer reviews.  As you shop, compare:

  • delivery costs
  • warranties
  • environmental standards (for ex., CARB = OK to be sold in California)

Live in an apartment, condominium or modest home with access to an outside patio or small back yard, you’re looking at a small, portable unit that’s as quiet as you can find. (Propane generators are quieter than gasoline.) An example: the Champion Power Equipment 42436 1500-Watt Portable Generator, CARB Compliant costs $201.88 as of today. These items have to be shipped via ground so it may take longer than you’re used to for delivery.

Live in a Single Family Home, 3-5 Bedrooms, with outside access to patio or private yard? You can probably use a larger unit and won’t worry so much about noise or fuel storage.  For about $330, you can get something like the DuroStar DS4000S 4,000 Watt 7.0 HP OHV 4-Cycle Gas Powered Portable Generator.

Large Home or Small Business that still needs to continue running, even on a reduced basis, may require something like this model.  (It’s the one in the photo above, with wheels and handles that make it LOOK portable, but it weighs a good 200 pounds!Westinghouse WH7500E Portable Generator, 7500 Running Watts/9000 Starting Watts at $865, with free scheduled shipping.

Medium-Size Business that cannot afford to shut down for any sustained period, you’re looking at what’s called a “standby” generator. These are installed permanently and go on automatically even if you’re not there.  This example (shown in photo above.) runs on propane or can be connected to a natural gas supply (probably not the best idea if you live in earthquake country). Cost: $2,549 with extra $20 for shipping.Generac 6439 11,000 Watt Air-Cooled Steel Enclosure Liquid Propane/Natural Gas Powered Standby Generator (CARB Compliant) without Transfer Switch

This should be enough to get you started on some sensible shopping!

When Less is More

Share

Let’s face it. We are spoiled. We enjoy our creature comforts and we’ve come to expect them. From ambient lighting, ever-present refrigerator and freezer to air conditioning and the convenience of cable TV, wall-to-wall wi-fi and, oh yes, let’s not forget the electric toothbrush and hairdryer – we assume they’ll be there when we turn to them.

But when the lights go out . . .

and the power company says it will be 5-7 days before power can be restored, what now?

In our CERT community, the logical answer seemed to be to go out and buy a generator. A 6-8,000 Watt model would power a whole house; it seemed like a reasonable action to take. We voted on it at our monthly CERT-Leadership Team meeting and decided to purchase one generator as a pilot project. If, after testing over a 90-day period, the generator performed as well as we anticipated, we would put forth a plan to acquire additional units to be rotated among the more critical homes in the community.

Sounds like a rational plan, right?

Generator to power a whole house

Large enought to power a whole house

The generator we purchased came in a large box. There were images showing wheels and handles, but the thing required assembly.

I thought two of us could handle it. I was wrong. We managed with the help of a third person . . . barely!

When we got the wheels on we were at least able to move it, but still, only slowly. Much to our disappointment it was becoming apparent that our original plan was lacking. Actually it was turning out to be downright unrealistic.

To compound the challenge . . .

As it turns out, these generators cannot sit idle for long periods. Once fired up, they must be run at least every 30-45 days. To store or sit idle longer than 30 days, it is recommended that you follow specific storage procedures to prevent damage to the machine.

The warnings also make it clear that the 8kW generator can be dangerous to run if you don’t follow safety instructions. It can, for example kill you in a matter of minutes if you run it inside! Or it can start a fire if you turn it on with appliances improperly connected.

And, since most modern homes include a wide array of appliances, it’s really questionable that even an 8kW generator will be able to power an entire home.

Here, for example, are some typical running wattage requirements for a number of common appliances:

Appliance Req’d. Watts Appliance Req’d. Watts
Ceiling Fans 750+ Radio/Stereo system 75 – 450
Computer & Monitor 275 Television (color), 27 inch 115
Computer, Laptop 60-75 Television (color), 36 inch 140
Dishwasher 1,200 – 2,400 Television (color), Flat Screen 125
Furnace 750 Toaster 750 – 1,500
Hair Dryer 1,200 – 1,850 Toaster Oven 1,250
Heater (Portable) 750 – 1,500 VCR/DVD 17-20/20-25
Microwave 750 – 1,000 Vacuum Cleaner 1,000 – 1,500
Refrigerator (18 cu. ft.) 750 Water Heater (Electric) 4,500 – 5,500

So maybe a smaller generator makes more sense.

If you look at this list of appliances a number of things become clear:

  • A smaller generator/inverter can handle most critical tasks, just not all at once.
  • If you run a high-output generator just to power a refrigerator/freezer for half an hour a couple of times a day, you’re wasting precious energy and using up fuel . . . fuel that’s expensive as well as difficult and even dangerous to store.
  • Smaller, lightweight units are far more portable and economical to run.

What about price?

Now, many will argue that the initial purchase price isn’t all that different. While you will likely pay $400 – $600 for a quality unit putting out 2,000 – 3,000 watts and $600 – $800 for a unit that produces 6,000 – 8,000 Watts of power, it seems like the larger output machine is a better bargain.

Whatever “savings” you might enjoy, however, will quickly disappear and be overshadowed by the large quantity of fuel you are required to store, and the rate it is consumed by the larger unit. Those, compounded by the maintenance requirements and lack of real portability, make the smaller units far more flexible and economical to operate.

In our estimation, this is an excellent example of where less is more.
