My first step was asking fellow writers if they knew of a back-up generator
that could be used with computer equipment. I kept hearing the name Honda
over and over, especially the 3,500-watt portable generator. This could
supposedly run basic home devices (lights, refrigerator, hot water heater,
TV, etc.), as well as a computer, monitor, and printer. Some writers swore
by online UPS (Uninterruptable Power Supply) units, an idea new to me.
I already had a UPS, but it didn’t allow me to continue working; it just
saved my computer from frying if there was a power surge or outage. This
intrigued me, so I began to surf the Web looking for answers.
Honda’s site had plenty of generators to choose from—but trying to find a contact person, e-mail, or phone number was next to impossible. I did find the generator everyone recommended, the EG3500, at http://www.hondagene rators.com/generators/economy/index.html.
Setting up is simple and the generator should be tested once a month for 15 minutes if its use isn’t needed for long periods of time.
I found the same sentiments from other generator dealers, including Certified Electrical Distributors, Inc. in York, South Carolina. Tommy Carroll, their national sales manager, says a smaller portable generator such as the EG3500 is fine for people on a budget, but he does throw out some cautions.
The fuel is very flammable and unstable, plus needs a lot of care if it sits for a long period of time, he warns. It seems to break down and needs additives to boost the octane and remove any moisture that has accumulated in it. It also emits carbon, so it should only be used in a very open location (usually a separate shed out back). People try to place a generator in their garage, causing not only carbon monoxide problems but a fire hazard as well.
If that doesn’t scare you a bit, then consider that most portable generators have a very small fuel tank requiring it to be refueled often during a long outage. Some people don’t shut the generators off while doing this and often cause fires. Then there’s the distinct possibility of overloading a generator with too many ungrounded extension cords. More food for thought.
The generator Certified Electrical Distributors recommends is an automatic unit that comes with an automatic transfer switch, Carroll says. You can choose from a propane, natural gas, and diesel fueled model. The sizes most commonly used are 5 kilowatt to 40 kilowatt, plus options such as an enclosure made to fit the unit or if it will be placed inside a building in a room, proper ventilation, or exhaust ductwork.
Of course, the price is a bit higher—you’re talking more in the $4,000-10,000 range now.
Other generators recommended to me by fellow writers included the Generac
4000xl, at around $700, SunWize Solar PowerWize2K, starting at $899, and
VoltMaster A50L Diesel, at just over $2,000. The general consensus was
to get a diesel instead of gasoline unit (gasoline goes bad quickly) or
spend the extra $150 or so and convert it to propane or LP.

Online UPS units
Now about those online UPS units. I found Falcon Electric, a company in Monrovia, California, that specializes in these. I looked at their Web site first, then got in touch with them. Mike Stout, their engineering manager, touted the virtues of online UPS units. So what are they?
An active online UPS is used with a generator, after a generator comes
on, he explains. I don’t recommend using a generator alone, even if they
claim their output is clean—you don’t want to take a chance with a computer
system, especially if you use it for work or important projects.
Stout recommended the SG series of online UPS units from Falcon.
I can attest to that - we get brownouts here in the boondocks all the time.
A true online UPS is the only one that provides the maximum protection against major power problems. This is done by converting the incoming AC utility voltage to a DC voltage. From this, an AC voltage is then completely regenerated by the UPS, providing a clean, regulated source to your equipment.
An online UPS would be good to have even if you don’t experience power outages, and the SG Series offers optional external battery packs if you don’t want to get a generator. Whether your application requires a few additional minutes or an hour, the SG Series is ready. Plus, it comes with software that saves everything you’re working on automatically. A very nice touch.
The price? The 600VA model is $790 and the series goes all the way up to the 6KVA model at $5,890 (used by hospitals and large businesses).
Other UPS units to consider include the Mitsubishi 7000 series 1000VA unit (their smallest), about $1,000, APCs Back-UPS Pro 280-1400VA, from $179-719, and BestPower UPS PatriotR Pro II 400-1000VA, $119-$529.
I have to say, I was sold on at least getting one of these, if not a generator, too.
