5.0 out of 5 stars Less is Better, December 9, 2005

By 

Roger "ByTheNumbers" (New England, USA) - See all my reviews

This review is from: Porter-Cable BSI550-W 5,500 Watt Generator with 10 HP Engine (Lawn & Patio)

As an engineer, I'm obsessed with numbers and choosing a generator presents the perfect opportunity to play with them. I won't bother you with a lot of technical details, but this is the generator I chose after 4 months of deep, deep researching.

First criteria: my needs. I wanted to power a 3 bedroom home with a finished basement through the harsh winters in Maine. Here are the devices I setup as an absolute necessity to power up during an emergency:
1) Water well pump, 2) Furnace blower, 3) Basement Sump Pump, and 4) Refrigerator. Here are the "good-to-haves": 5) lights in the kitchen and main living room, 6) pellet stove, 7) oven range. And, finally, just the "nice-to-haves": 8) TV, 9) microwave oven, 10) computer. And here's what gets excluded: all the 2nd floor in the house, garage door opener, bedroom lights, everything else not listed above.

By adding the must-haves and nice-to-haves, a 5500 W generator takes care of business. One of my concerns: since I have a lot of electric motors to start (well & sump pumps, refrigerator, furnace blower) this requires a good surge capacity from the generator. In case you don't know, a motor takes a lot of electricity to start up, between 3 to 5 times (!) over their normal running wattage. Here's the caveat: not all motors should start at the same time, so then determining what your surge wattage is becomes an "art". Consumer Reports simply tells you to ignore the surge wattage, since all the generators they tested started their appliances with no problem. Well, the thing is, they don't mention what appliances they tested and how they started them (manual selective start or just regular use?). So, their point is taken, but surge wattage can't be simply ignored (it shouldn't be the only criteria to buy a bigger generator, though).

Well, this generator, with a 9000 W surge, is the biggest I've seen in all 5500 models -- it beats them all. So, this model is perfect for me, as it meets the criteria I've selected above. It even powers my computer and TV (with surge protector) if the oven range is turned off.

This is very important: if you turn your generator on, you're in "emergency mode". This means, you lose some comfort, some conveniences. You just try to keep the inconveniences at a minimum. Well, if you don't agree with my assessment above, you're looking for the wrong type of generator. If you want to power your entire house and live as if power wasn't lost, you need a stand-by generator, not a portable one. Of course, they cost a lot more money (good and powerful ones start at over 10,000 bucks). That's a lot of money to pay not to be inconvenienced. Now, since you're looking for portable ones (I assume so since you read this review so far), you'll have to give up something. Basically, you can't throw a pot roast party for 20 guests if you lose power; like I've said, you're in emergency mode. Cooking a gourmet meal shouldn't be a priority, order out, get pizzas. You get my point. So, decide what you want to power in an emergency situation.

Second criteria: fuel consumption. I was just about to purchase a 7500 W model with 13000 W surge, for about $1,400 bucks! Have you seen the fuel consumption for these generators? Only 8 hours, tops, at half load. This ones rates at 13.5 hours. Well, with gasoline prices hovering at around 2 bucks a gallon, do the math if you run a larger generator for 2 weeks (a possibility over hurricanes and severe winter storms): it may cost you over $500 dollars in gas! Of course, with this generator the cost drops significantly and you don't have to wake up in the middle of the night to refuel it. This is very important to me, especially during cold winter nights.

Third criteria: quality of parts and components. I wanted a good engine and a good quality brand name generator. This one meets my criteria. It's not a Honda, but they're overpriced anyway and most home-owners and occasional users won't benefit as much from them. Construction workers, electricians and contractors may benefit some from their cleaner electrical output and "quietness", but no generator is really quiet. I ran a Honda once at my house and, sincerely, they're loud too. You just have to work around their noise, it's one of the inconveniences of being in emergency mode. Compare the noise of a generator to 5 kids screaming at the top of their lungs. With a Honda, you have 4 kids screaming at the top of their lungs. My point: 4 or 5, it doesn't matter, they're still loud.

Finally, here's what I mean for "less is better". If all you want is to power your house during an emergency, there's a good chance you'll be wasting your money if you buy a 10,000 W generator or bigger. First, 10,000 Watts is a lot of juice to deliver and you'll need 50 Amp plugs, cables, and a big transfer switch box if you want to use all that juice. They're ALL more expensive when you talk 50 Amps. The regular 30 Amp already costs money, about $100 for cable (depends on the length you want), $300 bucks for the transfer switch with 8 to 10 breakers (a bit less with <6 breakers, but then you can't power as many appliances), and then installation labor. With my generator, I paid less than $1,500 for everything: generator, transfer switch box (required by law or you're liable, the risk is all yours if you chose to back feed to your house), cable, and labor. With a bigger unit (50 amps), good luck, you're talking a lot more money (I stopped adding up when it approached $3,000, including generator).

All in all, this generator is a winner; it powers my house (what I want), it has good fuel consumption, it's also "lighter" (160 lbs, compared to 250+ lbs for 7500W ones), and the price is good. I hit literally dozens of generator sellers on the Internet and locally for many weeks, and this one at Amazon.com beats them all. This may change, of course, but I'd still pick this model.

Some drawbacks: 1) no electric start. Well, they're notorious for not working anyway, especially in cold winters. I borrowed a generator from my brother-in-law and the electric start rarely works, we always end up pulling the cord to get it started anyway (both his and my generator start at most on the second pull, 100% of the time). 2) No Automatic Voltage Regulator (AVR). This means the voltage output can vary quite a bit and may damage sensitive equipments. The manufacturers' manual requires that you use UL listed surge protectors for TV's, stereos and computers. I do that and so far, no problem. Only more expensive generators have AVR's and I didn't feel it was justifiable to pay hundreds of dollars more for one (then you have the fuel consumption issue if you buy bigger! Remember, in this case: less is better!).

Like insurance, you hope you don't have to use a generator, but when you need it, you will be glad you have it.
I hope you have good luck choosing and buying your generator. This one works really well for me. If your needs are similar to mine, picking this one is a no-brainer.

4.0 out of 5 stars Starts easy, runs good!, November 18, 2002

This review is from: Porter-Cable BSI550-W 5,500 Watt Generator with 10 HP Engine (Lawn & Patio)

The shipping of this generator was good. The shipper was ABF Trucking. Their local agent coordinated with me before delivery, which took place two days early.
The generator was shipped with the portability kit in the same box. The instructions for assembly were clear and understandable, but did not help me attach the foot brackets to the generator frame. The frame was drilled but not tapped, so I could not get the screws that were provided started. I used a 1/4-20 tap to thread the holes. Assembly time was about two hours.
After following the preparation instructions, putting fuel in the tank and oil in the engine, and reading the starting instructions on the top of the fuel tank, I pulled the starting cord once, and the engine started. This generator provides enough electricity to run my water pump (1 HP), start my oil burner and run the circulating pumps, run the refrigerator, TV, and provide 1500 watts of lighting. It still had capacity left over, since it handled the startup load of the water pump very well. At $679 this generator is a great backup power source for the average size household. A voltmeter and loadmeter on the control panel would be nice, but at this price I think that is too much to ask.

5.0 out of 5 stars Porter-Cable BSI550-W 5,500 Watt Generator, December 8, 2002

By 

Anthony J. Kulakusky (Oxford, Ma. United States) - See all my reviews

This review is from: Porter-Cable BSI550-W 5,500 Watt Generator with 10 HP Engine (Lawn & Patio)

I received this generator on 12-03-02. I purchased it to supply electricity to my home during power outages. I installed a transfer switch beside my main electrical panel and tried it out. It worked better than I had anticipated, running my 220 volt artesian well pump, my oil fired furnace, my refrigerator freezer, TV and many lights. I made sure the refrigerator's compressor was on, the furnace was running and the well pump was cycling so that I would be sure it would work during a real power outage. This generator started on the first pull and ran great. On the same day I received it, I saw the same generator at Lowes for eighty two dollars less, but customer service would not give me back one red cent.
