Aluminum generator enclosures are ideal for high humidity areas because they are resistant to rust and corrosion.

Living in Florida you should never choose a steel enclosure over an aluminum one. Even though the initial investment may be lower with a steel enclosure, in the long run you will be faced with having to replace the steel enclosure, incurring in extra parts and labor, it's just not a cost-effective decision.

In addition, rusted generator enclosures may expose internal components to the weather elements making them malfunction and sometimes causing major breakdowns.

 1. A generator is a major purchase and should be amortized over it's expected life:

A generator can last 10 to 20 years if properly taken care of. For most residential applications a quality generator will last a life time if used for standby/emergency backup. For this reason we recommend the purchase of a quality unit with suitable features for your application. A cheap or bargain price will become an expensive lesson when your buying the second or third generator or when the power goes out and the cheap unit fails. Buy right the first time, spend a little more on quality. Don't be cheap at first and spend more in the long run.

Chinese (or other foreign) generators sold on the internet look like good deals but they are not.  Here's why:

(a). Most Chinese generators are copies of U.S. Made units but they are not good enough copies to use U.S. manufacturers spare parts. Even Chinese spare parts are such poor quality they wont fit.

(b). Many Chinese generators do not really have EPA approval and they have phony environment certificates. It is very hard to verify there certificates and the Chinese makers know that, so they just claim they have EPA approval. Most don't.

(c). Most foreign made non-EPA compliant generators have terrible fuel economy, produce excessive emissions and consume oil. Many of the countries that make these generators are the biggest polluters in the world so they don't have or enforce any environmental controls.

(d). Buying foreign generators hurts America! It not only pollutes our environment but it puts Americans out of work, contributes to the trade deficit, devalues the U.S. Dollar and ships U.S. economic power to foreign countries.

2) If your backup requirements are "occasional" and you only need limited power during an outage an inexpensive generator system will most likely meet your needs (air-cooled, 3600 RPM gasoline, diesel or gaseous units will work.

3) For us living in the coast, we are likely to need a heavy duty unit, one with high quality features to withstand heat and humid conditions. Most modern gaseous or diesel engines are reliable and fuel efficient. An 1800 RPM, liquid cooled generator will provide better fuel efficiency and longer life but will cost more initially.

4) The generator end is the usually the last thing to fail with heavy use. The insulation coatings on the windings are based on heat ratings and 'F' is good and 'H' is better. Some major brands manufacture their own generator ends and parts and repair is usually only available through them, some others use off-the-shelf industrial brands because parts are readily available and any qualified service repair center can service it.

5) Controllers are a vital part of most generator systems. The controller monitors the generator engine speed for hertz, the oil pressure and water temperature and other engine and generator functions. It shuts down the engine if one of the threshold settings for these controls fails. It also provides the auto-start function for the automatic transfer switch or inverter if one is used. Buy a unit with adequate controls. Don't buy glitz and features you do not need, just more things to take care of and go wrong.

6) A generator is a mechanical and electrical device that over time will need some service or parts. Make sure you are purchasing a generator system that will be supported in the future from a company that will be there to support you.

7) Know what you intend to run with your generator and make sure the generator you purchase will handle your load. We can help you with design considerations, load calculations and motor starting considerations.

Outdoor power equipment engines, including those found in generators, lawnmowers, chainsaws, and string trimmers, are susceptible to corrosion damage caused by E10, or gasoline that contains 10 percent ethanol.

While ethanol has been shown to cause damage to all engines, small engines found in outdoor power equipment run a higher risk of being damaged by ethanol due to less frequent use.

In storage, gasoline immediately starts to naturally oxidize and deteriorate.  The older it gets the more it deteriorates and the more likely it will cause hard to start and other performance issues that result from sticky deposits that clog the tiny passages in the fuel system.

In addition, ethanol in the gasoline attracts water.  Initially it mixes with the ethanol, but at higher concentrations it separates and settles to the lowest point, which leads to corrosion and starting and running problems.  The lower the fuel level in the tank, the more likely you will experience water contamination.

If the gasoline in your fuel tank and carburetor has significantly deteriorated during storage, you may need to have the carburetor and other fuel system components serviced or replaced.

Ethanol makes up about 45% of most gasoline in the U.S., and this percentage is expected to continue to rise. While ethanol may not cause damage to your car or pick-up truck, it has been shown to damage small engines that get less use due to seasonal storage.

How to Prevent Ethanol Damage in a Small Engine?

1. Do not use gasoline containing more than 10% ethanol in your small engine equipment, if possible use only ethanol-free gasoline.
   
2. Store your gasoline in a clean, plastic, sealed container approved for fuel storage. Close the vent (if equipped) when not in use and store the container away from direct sunlight. If it takes more than a month to consume the fuel in the container, we suggest adding a fuel stabilizer to the fuel when you fill the container.
3. Keep your engine’s air filter properly serviced. Check it before each use.
4. If you don’t plan to use your small engine equipment for more than 30 days, follow the storage guidelines in your owner’s manual.
   
   

Will gas-related issues be covered under warranty?
Most of the small engine manufacturer's offer a Limited Warranty that will covers defects in material or factory workmanship and will not cover fuel system damage or engine performance problems resulting from deteriorated fuel (consult your owner's manual for more information).

Power generators have two main components. A motor that burns fuel to supply power and a generator head that turns power into electricity. Together, the motor and the generator head comprise a standard generator.

Generators come in two basic designs: standby and portables.

PORTABLES:

Portable generators provide power in remote locations, such as construction sites and camping sites for short periods of time. In a pinch, they can also power essential equipment during a power outage. Portable generators tend to be smaller and less expensive than standby generators. They have built-in fuel tanks, which allow them to run anywhere, and standard power outlets that can plug into ordinary extension cords. Portable generators should never be run indoors as they can produce fumes that can cause serious health problems or death if used indoors.

STAND BY:

Standby generators offer anywhere from 7 kW to several hundred kW of power. They help offset the harmful effects of power outages. Installed permanently as an emergency power source for your home, cottage or business, standby generators are hardwired to your home or building electrical system and often get fuel from built in larger fuel tanks able to run for longer periods of time. Safety features can prevent injuries as well as damage to your generator.

Quality standby generators will shut down if they lose oil pressure, overheat, or are being worked too hard. Standby generators also have solid steel or aluminum enclosures, good mufflers to reduce noise, and be compliant with all relevant emissions regulations. Standby generators should be started up once a week and run for 15 minutes to “exercise” them – making sure they are ready when needed.

FUEL TYPES

Generators can run on several different fuel types: Diesel, Gasoline, Liquid Propane and Natural Gas

Diesel Fuel Generators:

Diesel is a popular choice of fuel for larger, commercial generators. Diesel generators tend to be dependable and somewhat less expensive to operate than generators that run on natural gas or propane, today’s diesels are very clean burning and do not smoke. Diesel fuel is also safer to store then gasoline and lasts longer.

Natural Gas and Propane Generators:

Standby generators can run on natural gas or propane. The standby generator connects to utility lines and draws fuel when necessary. Choose between natural gas generators and propane generators based on what’s available in your area. Unlike diesel generators there is more maintenance involved in these. Natural Gas and Propane generators can be sensitive to both fuel pressure and volume, so high-quality connections are important.

Gasoline Generators:

Portable generators commonly run on gasoline and are considered gasoline generators. Gasoline can not be stored for very long, so the maintenance and storing of your generator is essential.

KEEPING YOUR GENERATOR RUNNING COOL

Generators need an air cooling or have a liquid cooling system to prevent overheating. Like any motor, a generator motor creates quite a bit of heat, with faster generators producing more heat than slower generators. Generators made for the north American market operate at one of two speeds: 1800 RPM or 3600 RPM. 1800 RPM motors typically last longer and run quieter; 3600 RPM motors are smaller and lighter.

Air Cooled Generators:

Air-cooled generators cost less than liquid-cooled generators, but produce more noise and usually offer up to 20KW. Portable generators are almost always air-cooled, 3600 RPM models.

Liquid-cooled generators:

Standby generators 12 kW and larger typically run at 1800 RPM and use quiet, dependable, and effective liquid-cooled systems. Liquid-cooled generators typically cost more to purchase and maintain however will last far longer and are able to run full time.

DETERMINE WHAT SIZE OF GENERATOR YOU NEED

The electricity created by a generator is measured in voltage and watts. When choosing a generator, first determine your specific voltage needs and then you can pick a generator model that supplies enough wattage for everything you want it to run.

Generator Voltage:

Voltage is a measure of the “pressure” of an electric current. In the U.S., standard household current is single phase, 120 volts. Most houses have 120/240v service, meaning they have two 120v circuits that combine to provide 240v for power-hungry appliances such as electric ranges, central air conditioning, and water pumps. Many small businesses use this 120/240v service and can take advantage of 120/240v generators. Larger businesses often have different power needs and use three-phase power, which better runs heavy-duty motors than residential-standard single-phase service. In the U.S., three-phase power usually produces 120/208 volts or 277/480 volts and you can find 120/208v generators and 277/480v generators that handle these common voltages. Know what voltages your business uses now so that you can find a generator to match.

Generator Wattage:

Wattage measures the “volume” of electricity a generator creates. Wattage requirements increase with each additional appliance or piece of equipment you need a generator to power. The smallest generators produce around 800 watts while large industrial generators can produce 500,000 watts (500 kilowatts, or kW) or more. Small businesses typically require generators that can produce 15 kW to 100 kW.

Before choosing a generator, particularly standby generators, you’ll need to decide what equipment you want it to run. The “right” size electric generator provides just enough wattage to operate all your essential equipment. Common devices include refrigerators, freezers, security and access control systems, sump pumps, essential lights, electric gates or overhead doors, ejector pumps, well pumps, and septic systems. Keep in mind that every electronic device you add to the list will increase the wattage you need. While a single light bulb will only add 70 watts, a mid-sized central air conditioner can draw 4000 watts or more.

Limit your choices to those devices that are truly essential during a power outage and you’ll keep your total costs down. Too few watts and you can overwork the electric generator, potentially damaging it and anything plugged into it. Too many watts and you’ll waste money on the initial generator purchase and on fuel. Accurately determining the watts your equipment requires will help you get a generator that can meet your electrical demands without spending too much.

Discover how much wattage your devices require:

Always investigate the power needs of the devices your generator will need to support instead of estimating. Although you may be able to come up with a good guess as to what size generator your business or home might need, you should always total the wattage requirements of your devices before finalizing a buying decision. More is always better.

We can send an electrician to measure wattage: He will use an amp meter (a device that measures electrical current) to determine exactly how much power each piece of equipment needs. Total the wattage the electrician measures for each device to get your baseline power needs.

INSTALLING YOUR GENERATOR

Get to know exactly what the installation of your generator will involve before committing to a purchase.

Standby generators wired into your home or business’ electric system require proper installation to prevent generator failure or overheating, and damage to your existing wiring and equipment. Standby generators can be sensitive to both fuel pressure and volume, so high-quality connections are important.

Location:

If you plane to make a permanent hook up to your home or building the location of your existing electric service panel is important. The generator will sit outside but near your building, much like a central air conditioner, and for ease of installation, it’s best if it can be positioned near the electric panel. The generator will need to be installed on a level surface – most commonly, a concrete pad. If you are using a portable generator then it is not as important however should still be kept a few feet away from your home and never indoors or in a garage.

Transfer Switch:

To connect a generator to your existing electrical system, you’ll need a separate device called an transfer switch. The transfer switch is an essential a safety system that prevents your generator from feeding electricity back to the neighborhood power grid. When the power goes out, the generator can be started up, and after a few seconds to let it stabilize, the transfer switch can be turned onto connect the generator to your home. When power comes on again you can turn the switch off and disconnect the generator and return your setup to normal. Some larger generators come with an automatic transfer switch that will sense a power failure, turn on the generator and switch itself on and off automatically. Installing a transfer switch may require local permits and always requires a professional electrician.

Consider installing a dedicated electrical sub-panel: In addition to the generator and transfer switch, you may want to invest in a dedicated electrical sub-panel, as well. Only your essential equipment is connected to the sub-panel, which is connected to the generator. That way, when power fails, your critical devices will get the emergency power without the risk of overworking your generator or having to turn off or unplug other equipment.

GENERATOR MAINTENANCE

Well-maintained generators can last a long time. Diesel generators require the least amount of service and are the easiest to maintain. There are no spark plug to change, no carburetor to clean or ignition cables to ware out.

Generators no matter what type require regular oil changes about every 100 hours or once a year. The cost of an oil change is cheap in comparison to the extended life you give your generator by changing the oil often. Remember generators often end up running non stop at high speeds for hours or days. Your care does not even get that much use. Even if you do not use a generator for a short period of time, change the oil anyway. Oil does go bad and break down over time.

Check air filters and fuel filters and replace as required.

And most importantly, follow your manufacturer's recommendations.
