Pros and Cons of Investing in an Industrial Backup Generator

If you have a business, whether it’s a restaurant, service station or any other business for that matter, you always risk the chance of a power outage. A power outage, especially one that lasts for more than half an hour, can have a devastating effect on your revenue and business.

For this reason, many people talk about the merits of using an Industrial Backup Generator. Many claim that the frequency of power outages is low enough to make investing in a backup generator unnecessary.


Others claim that you can increase your competitive advantage by using generator and that it will pay for itself in time. So the real question is, do the pros outweigh the cons? Let’s have a look at the cons first.



Industrial backup generators are expensive

Of course, a commercial generator can carry quite a hefty price tag. This is especially true for a small business that does not have the budget to spend thousands of dollars on a generator.

Yet these are the businesses that need it the most. Imagine there’s a power outage, and all the gas stations are without electricity, unable to accommodate their customers. If you were the only business running on an emergency generator, you can expect a huge surge in customers coming your way. This would otherwise be impossible without an industrial generator.

But this still does not mean that every business can afford a backup generator. However, there is really no excuse for not getting one, because there are plenty of opportunities to get them at affordable prices.

At Bell & Orders, we pride ourselves on providing the highest quality commercial backup generators at affordable prices.


Fuelling a generator is costly

When it comes to fuelling a generator, we need to keep a few things in mind. First of all, you won’t be using your generator all the time, but only when there’s a power outage.

Another point to keep in mind is that there are three fuelling options for industrial backup generators:

  • Diesel
  • Natural gas
  • Liquid propane

Diesel, while being the most expensive, is not necessarily the best. Natural gas is renewable and very cheap, making fuelling a lot more affordable.


Too much trouble to maintain

With a bit of care, a backup generator can last for years. It is not necessary to check it every single day. Service it the way you would a car, after using it.

With some basic upkeep you won’t be facing big problems and neither should you spend a lot of time doing it. If there are serious problems, like a part that stopped working properly, all you have to do is replace the broken part and you’re good to go.

The analogy is simple. Would you avoid buying a car because it needs some basic maintenance? Of course, not! The same goes for a commercial generator for your business.

As you see, the cons are not that bad after all, and can be overcome quite easily.

Now, let’s talk about the pros.



You see, natural disasters are happening more and more frequently in this day and age. Bad weather, hurricanes, floods and other calamities can all cause a power outage.

While you may have no control over these things, you certainly can control how you handle the situation.

A power outage that lasts for more than an hour can potentially destroy a business. However, as you will see in the following paragraphs, being prepared gives you an incredible advantage over your competitors.


Risk management

Let’s say you own a factory or a telecom company. A storm hits and a power outage occurs lasting the entire day. Can you imagine what damage this will bring to your business?

However, if you have an emergency generator at hand, you would be able to keep going as if nothing happened – no complaints from customers, no loss of revenues.


More revenue

This is when things get interesting. Have you ever heard of a business making extra money during a power outage? Most likely, no.

In fact, most businesses lose thousands or even millions of dollars a year due to power outages. Or, rather, not being prepared during an outage.

Interestingly, people are attracted to a business WITH power during an outage, like bees to honey.

We have mentioned one such example previously in this article. This does not only apply to gas stations however, but to many other businesses.

Imagine there is a power outage in the city and you are the only restaurant with power. Customers will line up to get a table at your place for this simple reason.

You get a competitive advantage because there are still a lot of businesses that do not understand the importance of an industrial backup generator, and therefore suffer great disadvantages during a power outage.

Are you convinced of the importance of getting a commercial generator for emergencies? Then you are in the right place.

The Definitive Guide to Buying a Marine Generator

Are you a boat lover? Personally, I love the ocean and the sense of excitement and adventure it brings. There is nothing more enthralling than taking my boat out into the Caribbean waters for some recreational fishing. However, I know that going out into the ocean can be very dangerous, and it is essential that you have top notch equipment on board to ensure your journey is safe and successful.

Diesel Generator

In particular, one of the most important components of a boat is the marine generator. This makes everything on board functional: minor electronics, air conditioners, refrigerators, hydraulic systems, communication systems etc.

In this article, we will look at some of the important factors and features to look for in a marine generator before buying.

The first factor is the size of the marine generator. This needs to be in line with the size of your boat, whether it is a luxury yacht, tug boat or small fishing vessel. If you purchase a generator that is too small for your boat’s needs then it can cause electrical problems, wear out easily and generally be a pain in your rear. However, this doesn’t mean you should buy a huge generator since this can be equally damaging as well.

Instead, make sure that the generator is sized so that it runs between a 35 and 75% load which is optimal. In order to estimate your load, you will need to have your generator dealer analyse your boat’s requirements to determine which size generator is best for your boat’s specific needs.

Another feature to consider is whether to purchase an AC or DC generator. Thankfully, this is an easy choice since most boats nowadays use AC current. However, if you have an older boat, then you might have to purchase a DC generator. Unfortunately, DC generators have become difficult to find and are quite expensive to maintain.

One pressing question many boat owners have is whether to even buy a generator at all. There is the option of using an inverter instead of a generator. However, this only applies in certain conditions if the boat has a relatively small power requirement i.e. between 1,000 and 3500 watts. However, if you have a boat with more power demands and an electric motor, then you will definitely need to buy a marine generator and in some cases, both a generator and inverter.

Next, you will have to consider the fuel that the engine of your boat uses. Why does this matter when choosing a generator? Well, there are both gas and diesel generators available and you should always purchase a generator that uses the same fuel as your boat’s engine. However, always remember to look for generators that are spark free, as you certainly don’t want any explosions occurring when you’re out at sea!

Keeping your generator cool is another major factor that has to be closely considered. The main options you will have are generators that are cooled via sea water, keel cooled or use a heat exchanger system.  Similar to my point above, your generator should also use the same cooling system that the engine of your boat uses which makes it quite easy to determine which cooling system to use.

Another major factor is the marine generator’s engine. This is the heart of your generator and it is best to choose a generator that has an engine that is easy to repair, install and service. Also, the power generated will either be single or three phase. Small generators usually have single phase. However, these are surprisingly much more expensive than three phase engines. The three phase powered engines are cheaper and well suited for running and motor starting which makes it the preferred choice.

As you can see, there are numerous factors that need to be considered when purchasing a marine generator that takes time, effort and specialist knowledge. However, you don’t have to learn all of this on your own as marine generator providers such as Bell & Orders at have qualified experts to help you choose the best generator for your needs. Bell & Orders also offers repair and servicing, so be sure to check them out today!


Important Facts to Know Before Buying a Marine Generator

In theory and application, a marine generator isn’t much different than any other generator. A marine generator is typically powered by diesel or gasoline to produce energy that is converted to electrical energy inside the generator. This electricity can then be used to power various appliances and equipment inside a boat. You’ll find a marine generator in just about every larger boat out there, from fishing boats to yachts.


However, it’s important to note that there is a huge difference between a normal generator and a marine generator. For this reason, a standard generator should never be used on-board a ship. Many generators are far less efficient in a moist environment and it could cause them to stop working altogether. When water splashes on the boat, your average generator would be out of commission.

Marine generators, on the other hand, are designed to survive the harsh and wet environment of the boat. This requires different design techniques on the outside and alternative components on the inside. Many marine generators may utilize hydraulic pump systems, use more durable material, include H Class insulation, and have other features that make them more efficient for life on a boat.


Why You Need a Marine Generator

You may be wondering why you need a marine generator. After all, you have a battery in your boat and you could always use an inverter to create Alternating Current from the battery. This is perfectly fine as long as the power consumed remains under 3,500 Watts.

Unfortunately, this is rarely the case, as a single toaster consumes more than half of that limit. If you’re running any serious appliances, such as an air conditioner, a refrigerator, or any combination of smaller appliances, then you’re going to need more energy than your batter can supply.

A marine generator is perfect for the job. If you choose a generator of appropriate size, then it can easily power all of your appliances without putting any additional strain on the boat’s battery. Simply put, marine generators are a must have item for any serious boater.


Safety Concerns

As with any type of generator, there are always certain safety factors you must keep in mind when choosing a marine generator. These safety factors could be for your good or for the environment, but they always help. For example, it’s common knowledge that any generator produces some pollution as a by-product. This is already bad for the environment, but it gets worse. If your boat is stationary, then this carbon monoxide pollution can actually build up inside the boat. The gas is highly poisonous and can have some serious adverse health effects if allowed to build up in the cabin or other enclosed area.

For this reason, you should keep emissions in mind when you are shopping for a generator. There are some generators built with sensors that cut off the generator when carbon monoxide levels climb too high.  You should also consider installing similar sensors throughout the boat to ensure safety at all times.


Importance of Appropriate Voltage Regulation

When choosing a new marine generator, you should pay close attention to the voltage regulation. These numbers always coincide with the AC frequency, which is either 50Hz or 60Hz. The former is for European standards while the latter is used in America.

A 50Hz electrical appliance also runs with a 220 V regulator while for American appliances, the values are 120/240 V. For standard appliances 120 Volts is used, while 240 is used for motors, such as air conditioners, dryers, and equipment.

It’s important that the generator’s voltage is listed clearly.

The frequency of a generator is determined based on its motor speed. The best choices are either 1,500 or 1,800 RPM. The first is for 50Hz and the second for 60Hz. There are faster and slower options, but none are as effective as these standards.

Use this information to choose a marine generator that is modern, safe, effective, and reliable. You don’t want to invest in a generator that will break next month, so put time into finding the best brands and manufacturers in your area or on the Internet.

Important Decisions When Buying a Marine Generator

Do you own a boat? Whether it’s a massive cruise boat, a yacht, a tug boat, or even a fishing boat, you’re going to need some kind of electricity on board. Not just the electricity from your battery, which can be connected to an inverter to power some very small appliances. What you need is a heavy duty marine generator that can produce enough wattage to power all of your appliances on board.


Of course, the more appliances you have, the larger the generator you will need. The size of the generator is just one of the many decisions you’ll have to make when buying a new generator. Other important decisions must be made, such as fuel source, type of current, motor type, and operating speeds.

Many of these important issues are addressed below. For some of them, only you can answer as to what best suits your budget and your boat. For others, such as current type, there’s usually only one smart choice to make. At any rate, each decision still requires your full attention before making a choice.


Choosing an Operating Speed

One of the most important decisions you need to make is on the operating speed of the motor and the current frequency itself. Standards for Alternating Current (AC) are different in America than Europe and other countries.

In America, the standard is 60 Hz, which means it completes an AC waveform 60 times per second. However, in Europe, the standard is 50 Hz.

While this difference might sound negligible, it makes a big difference and most appliances operate at one frequency or the other. You’ll need to choose a generator that produces the appropriate frequency for your appliances, which usually depends on where you live. The frequency of the electricity isn’t the only concern when it comes to speed.

The frequency of the current produced by the generator is actually determined by the speed of the motor, which is usually producing the AC as it revolves around magnets and inducts the current. A motor that speeds at 3,600; 1,800; or 1,200 RPM will create a frequency of 60Hz. Notice how the speeds are all divisible by 60. The same rule applies to 50Hz motors, which spin at 3,000; 1,500; or 1,000 RPM.

Of the 60Hz variety, the 1,200 RPM motor is the least common today, primarily due to certain emission standards. The 1,200 RPM motor is about 33 percent slower than the 1,800 RPM motor, which is the common standard today. However, this slower speed means the motor often lives longer than other generators. The most common motors are four pole motors that spin at either 1,500 or 1,800 RPM for 50Hz and 60Hz respectively. The faster options are actually smaller, lighter, but also have the shortest lifespan of all the available generators.


Additional Features.

Choosing a generator with the best features is always the fun part. Do you know which features are important to you or which may be mandatory on your boat? Some features make life easier. For example, some generators come with additional or internal equipment that converts AC to DC through an additional outlet. This is great for those rare appliances that don’t have their own internal rectification components.

Other features are more for safety than pleasure. These features might include internal Carbon Monoxide detectors. This helps prevent a potential build-up of poisonous Carbon Monoxide. However, if you don’t choose a generator with one of these detectors, then you should take the time to install external detectors throughout the boat. It will help keep everyone on board safe. Choosing a generator with minimal emissions is also a good idea.


Choosing the Perfect Size.

Choosing a generator that’s too small means you won’t be able to power all of the appliances you need. Choosing one that is too large means you wasted money and electricity. You’ll need to find that spot right in the middle, which means you need to do the math and find out how much energy you’re using on your boat.

Your numbers may not be 100 percent accurate, but as long as they’re in the ballpark you’ll do okay. Remember it’s always better to choose a generator slightly larger than one slightly smaller than your needs.

As you can see, there are a lot of considerations when choosing the best marine generator. Each boat has unique needs, which means the same generator isn’t going to be the best for everyone.

Buy the Right Marine Generator for Your Boat

Whether you own a luxury yacht, a tug or a fishing boat, all these vessels are equipped with modern facilities such as refrigerators, air conditioners, hydraulic systems and watermakers.


An excellent marine generator is mandatory to run these equipment efficiently. The marine generator is considered the most expensive piece of equipment on-board a vessel after its main engine. This is why you need to be extremely careful when choosing a marine generator for your vessel.

This article highlights some of the most important considerations when purchasing a marine generator.

A quiet-running marine generator would be the dream of any boat-owner. Most of the current generators run on AC (alternating current) since AC can travel through wires without losing power in the process.

This has made DC marine generators obsolete.

There are a few DC generators in the market that are meant to re-power older type of boats, but they are quiet expensive compared to AC generators.

Before buying a generator, you must think about its location and space requirements. The generator would go below the deck, hence you must determine how easily you can access the space for maintenance and installation. Also, be aware of how the new unit will affect the weight distribution on the vessel. Tight spaces can accommodate compact marine generators. There are many compact generators in the market right now. An average compact generator would measure at 28X15X17 inches and weigh just 188 pounds.

For the convenience of all concerned, you should choose a generator that operates on the same kind of fuel as your boat, yacht or tug. If your vessel is operating on gasoline, you must choose a generator that operates on gasoline. This will allow you to tap the main tank for fuelling the marine generator too.

Your convenience matters the most here. However, there is one exception: For a compact boat that runs on gas, you should most probably install a diesel generator for safety purposes. Since the generator is installed on the lower deck, there could be ventilation issues with gas generators. Diesel is less volatile than gas and would best suit such compact spaces. Large boats usually use diesel generators. Hence diesel generators are the most popular in the market right now.

Marine generators are rated by kilowatt output. There are generators starting from as little as 3.5 kW to as high as 200 kW. When choosing the right model, add up all the power needs of the accessories you plan to run on your yacht or boat.

Your generator should have at least 20% more output than all the power requirements added together. Don’t think that more is better when it comes to power requirements. A generator that runs at insufficient loads could lead to carbon build-up and other major complications.

Generators are water-cooled. Before installing a generator, you will need to install a water intake with a strainer in order to avoid debris from clogging the cooling system. Generators also need air to operate. For example, a yacht-size diesel generator requires 1,500 cubic feet of air per minute when it operates at peak output. They also need an exhaust system that is separate from the main engine’s exhaust system of the yacht or boat.

Thanks to isolation mounts, underwater exhausts, mufflers and insulating shields, today’s generators are quieter than ever.

There are Quiet Generators that generate just 66 decibels from a distance of a meter away. Gas generators are famous for emitting carbon monoxide (CO), which is detrimental to the environment. But the latest generators are manufactured to emit low-CO emissions to the environment. They are actually environmentally friendly than the older types.

The above information will come in handy when you’ve decided to purchase a marine generator for your vessel.

But where can you buy a marine generator?

How to Choose the Best Marine Generator – Tips and Pointers

Choosing a marine generator is about as difficult as choosing a boat in the first place. There is a lot of variety in the market, even though it may not appear so at first. Those who aren’t willing to stop and look at the little details may find themselves on the wrong end of a bargain.


The generator is often the heart and soul of any boat or marine vessel. With all of those luxury appliances on board, such as televisions, refrigerators, and stoves, you’ll absolutely need to make a good choice in generators or you’ll quickly come to regret the decision.

The task of choosing the best marine generator becomes significantly easier as you do more research and learn more about generators, boats, and what exactly you’ll need to enjoy life on the water. This is especially important if it’s your first time shopping for a generator.

Here are some very important tips for buying a marine generator that’s right for your needs.


AC versus DC

Long ago, Thomas Edison and Nikola Tesla fought to see whose electrical current was the most efficient. Edison supported Direct Current, or DC, and Tesla supported the new Alternating Current, or AC. As AC was proven to be more efficient, especially when it comes to preventing energy loss, it eventually won and became the standard across the country.

Most appliances require Alternating Current and those that don’t usually have their own transformers and internal circuitry for converting the AC to DC. You won’t find many high-quality DC marine generators available on the market and it’s for a good reason.

Should you run across one, avoid any temptation to purchase the unique option. Some AC generators are actually equipped to produce DC electricity.


What About Inverters?

While they perform similar functions, there are major differences between inverters and generators. An inverter will take advantage of the Direct Current that your battery produces. It will invert and amplify this current into a higher AC level. This works well for controlling smaller appliances that consume less than 3.5kW, but nothing more. A generator uses an alternative fuel source to turn a motor and actually generate an electrical current. So if you think a simple inverter will be enough to enjoy life on a boat – think again.


Type of Fuel

As mentioned, a generator requires an alternative fuel source to produce the energy to be converted to electrical energy. This fuel source is typically either gasoline or diesel. This is actually one of the easier choices to make because it’s in your best interest to just use the same fuel source as your boat or marine vessel. If it uses gasoline, then buy a gasoline powered marine generator, and the same for diesel. However, if you are working with gasoline as a fuel source, then make absolutely certain you are purchasing a spark-free generator.


Three-Phase or Single Phase

Without getting into the nitty-gritty of alternative current waveforms, it’s important to note that there is a difference amongst the Alternating Current produced by some generators. Some generators produce a single phase waveform, while other generators produce a three-phase waveform. Three phase generators are cheaper and actually more efficient. The catch is that most generators that produce less than 20kW only use single phase. If you want to experience the price difference and improved efficiency, then you’ll need to purchase a generator that is large enough.


Size of the Generator.

This also brings up another important topic: the size of the generator. It’s vital to choose a generator in the right size range. Too small or too large means overworked engine or wasted electricity. You never want a generator operating at less than 25 percent capacity and it’s best to leave it beneath 75 percent. Finding that sweet spot may require a bit of math on your behalf. Get an estimate of the power your appliances consume and find a generator that’s right for the job.

Use these pointers to choose an appropriate marine generator for your boat. Generators are never a cheap investment, so it’s important to make sure you choose right the first time.
