Factors To Consider When Buying Generator
Electric Failure, blackouts create havoc on businesses and homes. They cut down your precious working hours and restrain appliances from protecting people from intense frigidity and heat. The worst-case would be when power outages happen during the medical procedure requiring electrical assistance. That’s where generators can help you out.
Let’s discuss how to choose a reliable generator to continue with your work efficiently even after power outages.
What Type of Generator Do You Need
There are three types of generators: Home Standby Generator, Battery backup generator, and Solar Powered Generator. Before you choose, you need to get into a detailed understanding of each type.
Home Standby Generator
Home standby generators are designed ideally for the household to supply power at times of power outages. Most homeowners are infuriated with frequent blackouts; they can benefit from home standby generators.
The best standby home generator can supply power to the appliance during power cuts and stop supplying power when the electricity is back. The transfer only takes a few seconds to make sure of an uninterrupted and seamless power supply. Most home standby generators run on fuels like diesel, propane or natural gas.
Battery Backup Generator
With a battery backup power generator, you can continue to operate refrigerators, lights, and appliances in the event of power outages. The battery backup generators are connected with renewable sources of energy such as small-scale wind generators and solar panels. The battery is always charged at the time of need.
The time to extract the electricity from batteries depends highly on the size of the battery bank. Some mobile battery power systems can supply power to lights and cell phones for only a few hours.
Solar Powered Generator
Solar-powered generators use the sun as their source of energy to generate a voltage. The best solar generator kit includes solar panel battery, solar panel, battery charger, and an inverter. The solar panels can capture the sun’s energy to store it in the battery built inside the generator. The inverter converts the energy from DC to AC power before supplying.
As soon as the generator begins to supply energy, you can use the energy to power your household appliances. The home solar generator system is the best generator for portable electronics, a few industrial tools, and household appliances.
Type of Fuel
Generators run on different fuels like natural gas, propane, diesel, and gasoline. What fuel type is the most economical and burns cleanest? The fuel consumption varies as it depends on generator fuel type, weather conditions, electrical capacity, and generator brand.
Let’s discuss different fuel types used in generators.
Natural Gas is most commonly used as generator fuel to power the whole area that includes businesses, schools, and homes. It’s the only source of fuel that uses a local utility grid instead of on-site manual fueling to fuel power generators.
When your business or home is connected to this local utility grid, there will be backup power available all the time during power outages.
- Outperforms other sources of fuel during frigid weather
- Easy to obtain because of excessive abundance
- Encourage long-lasting operation of the generator because of its environmentally friendly nature
- Offers lower power output compared to other sources of fuel
Propane is known as the safest fuel for the environment. You can store the gas for an extended period, and it burns cleanly. Moreover, you can keep the gas seamlessly in different sizes of cylinders without any issue.
The propane gas is suitable for small generators which can supply power to all the home appliances.
- Comes with unlimited shelf-life
- Emission-compliant and clean-burning fuel source
- Generator relatively low engine noise
- Some containers of propane gas are flammable and pressurized
Diesel is another common type of fuel that costs very inexpensive compared to natural gas and propane. Also, diesel is safe as it is not flammable like most fuel types. The gas is used for various purposes, such as permanent power sources for recreational vehicles, emergency backup, and construction power sites.
- Easy to obtain
- Least expensive to maintain and operate
- Least flammable and easy to store for efficient re-fueling
- Generate more engine noise
Gasoline is ideal to use in most types of generators if it can generate power below 150 kW. The gas is used most commonly as residential backup generators.
- Straightforward fueling process
- Easy to obtain fuel source
- Ideal for most smaller and portable standby generators
- Comes with 12 months of shelf-life
Running Time/ Running Cost
Most power backup generators are not designed to generate long-hours of power supply. Some last for eight hours while others for twelve hours. There are some other generators which can even last for several days. Nonetheless, you should not let your generator run for seven continuous days.
The diesel generator runs for the longest period. You should be certain that the generator has sufficient gas. Proper fueling is essential for uninterrupted operation, so check the oil level after twelve hours.
Some portable generators need fuel that does not contain lead like gasoline generators. The generator will stop functioning when it runs out of oil to eliminate the generator’s risk of damage. Furthermore, the generator backup power is relatively more expensive than a regular electricity service provider.
Below you will find the average running costs of various fuel type generators:
- Diesel Generation Running Cost: With a $3.17 per gallon average fuel cost, the 20 kW portable diesel generators can power appliances like a water heater, well pumps, and HVAC. The running costs about $122 per day while consuming 1.6-gallon of fuel per hour.
- Natural Gas Generator Running Cost: Natural Gas generators are suitable for areas with frequent power outages. The running cost of natural gas varies as per the size of the generator. The 7 kW generator can cost $0.82 per hour and uses 118 cubic feet per hour fuel. In contrast, a 15 kW portable generator costs $1.71 per hour while using a 245-cubic meter per hour fuel source.
- Propane Generator Running Cost: The Portable generators with 20 kW power can burn 3.45 gallons of fuel per hour and consume 83 gallons in one day. The running fuel cost would be about $200.
- Gasoline Generator Running Cost: As of the 2018 July ratings, the gasoline price was around $2.89. Thus, a 5 kW generator can power the essential appliances by using 0.75 gallons of fuel in an hour. For a day, it can consume 18-gallons which would cost about $52 in a day.
Material: Copper Wire Generator vs. Aluminum Wire Generator
The generator, mainly a diesel generator, is divided into two components. One is the electric ball part, and the other is the power part. Most generators come with a copper wire generator, aluminum wire generator, or half aluminum and half copper wire generator. But which one is the best?
Experts and professionals suggest going for a copper wire generator because of the following reasons.
Aluminum has more resistance as compared to copper, so when the heat is generated to its maximum level, there is a possibility to heat up the generator. Furthermore, you cannot integrate copper and aluminum welding. Because the power line connection can be easily burned, an aluminum wire has low life than a copper-wire generator.
Aluminum wire generators produce additional 7 dB noise in comparison to copper wire generators. So, an aluminum wire generator produces twice the noise of a copper wire generator.
The circuit component resistance and heating value are directly proportional. That means the generator has higher resistance, so is the heating value. Furthermore, the copper wire comes with lower resistance which means low heating value and more energy-saving without wastage of heat.
The generator is used for conducting electricity, and metal materials have excellent conductivity. For example, the conductivity of aluminum wire is about 35.33 per cent, and that of copper wire is around 58.13 per cent. That is also one of the reasons why copper wire has more life and longevity than aluminum wire.
It is crucial to know the power you require during a power outage from the generator. Also, you need to consider whether to supply power to systems such as air conditioning, the whole house and just the refrigerator or not.
You should look out for two metrics while buying a generation, including running or rated watts and starting or surge watts. The surge watts are the power that appliances require to consume for the first few months. For example, 1600 starting watts of power are required by 11,000 BTU RC air conditioners to start operating.
Running or rated watts is the energy consumed by the device after it begins to run continuously. For example, a minimum of 1000 rated watts is required by an 11,000 BTU air conditioner to operate seamlessly.
The home inverter generators are large generators that are evaluated by kilowatt measure the electrical power output of the generator. By formula, one kilowatt is equal to thousand watts.
To evaluate the power needs, you should decide whether you want to power HVAC or air conditioning systems or not during power cuts as they consume more power.
For an adequate power supply, the size of the generator is crucial to understand. If you want to run an air conditioner unit, the generator should be of a size that can handle the power load. But, how can you determine the right size?
Take a look at the data plate of the air conditioner unit, which shows the size in Tons or BTUs. Generally, for every ton of capacity, there are 12,000 BTUs and about 3.517 kW of energy. If the generator has a capacity of three tons and 36,000 BTU, it will need an 11 kW or bigger standby generator.
You can always use the power calculator or generator size calculator to understand what is best suited for your home. However, the formula is Watts = Volts X Amps to calculate generator output.
A higher capacity generator is always suitable to power all the household electrical appliances. For instance, if all your factory appliances make 200,000 watts and home electrical appliances make 5000 watts, you need a 300 kW generator for the factory and a 7.5 kW generator for the home.
Let’s discuss the generators with different capacities along with their functioning and other aspects.
More than 300 kW Generators
The maximum capacity generators can power official establishments and large industries. The generators can easily power large equipment and heavy machines.
200 kW- 300 kW Generators
The high-rise buildings and large-scale industries need higher capacity generators as they need to power multiple AC units, elevators, and other large machines. Some of these generators are bi-fuel generators.
100 kW- 200 kW Generators
Bigger companies and small & medium-scale industries require generators with more than 100 kW capacities. On a full tank, the generator can power large appliances for a maximum of ten hours. Moreover, the generator can provide energy to marine devices such as trawlers and fishing boats.
50 kW-100 kW Generators
The generators with a higher capacity of more than 50 kW are suitable for restaurants and offices. They can efficiently power central air conditioning systems. Moreover, the offices with multiple computer units, fans, and light require 100 kW generators.
10 kW-50 kW Generators
To power larger appliances like water pumps, air conditioner units, and water purifiers, you need a more powerful generator. Therefore, a higher capacity generator of 50 kW can power such large appliances effectively.
Whenever a generator operates, it is accompanied by noise. However, the level of noise varies from a generator to generator. Some generators produce extreme noise that is harmful to the ears. For that reason, the Central Pollution Control Board has laid down permissible noise levels at 75 dB for industries during the daytime and 70 dB at night.
The acoustic enclosures are an engineered box or structure made to minimize the noise generated. Diesel generators that use acoustic enclosure make sure that noise level is attenuated such that it won’t affect the people in the vicinity.
Based on generator noise level standards, you can find three generator types. These include Generators below 120 dB noise level, Generators below 75 dB noise level, and soundproof/silent Generators.
Generators below 120 dB noise level
For industrial purposes, generators between 75-120 dB noise levels are suitable. Though the level of noise produced is extreme, they generate more power output required to power the large appliances. That is the reason most manufacturers will go for this generator.
Generators below 75 dB noise level
There is no denying that as the power output increases, the noise level of the generator will also increase. So, the high-capacity generators will produce noise on operations. The generators below 75 dB noise levels are suitable for commercial purposes because of high power demand.
Most silent generators come with a soundproof enclosure. The enclosure is made of composite materials that contain hard materials to reflect the sound. Moreover, the resilient and porous material absorbs the noise to transform into heat energy. That’s how the noise is eliminated from the surroundings.
Safety Features To Consider
Generators are usually safe when they are equipped with the below-mentioned safety features. If your generator has the following features, you can definitely go for the purchase.
Automatic CO Shutoff
The feature is of utmost importance in any generator. The shutdown features a turn of the engine when it detects harmful carbon monoxide in the area. Any portable generator use includes this feature and passes all the CR’s test to be listed under CR suggested generators.
You might find marketing terms like CO Sense, CO Shield, CO Detect, CO Protect, and CO Guard on a generator. To verify if the generator meets the safety standards, you can look at one of the following references:
- ANSI/PGMA G300 Certified Safety & Performance
- ANSI/UL2201 Certified for Carbon Monoxide Safety
This is another safety measure of eminent importance in a generator to provide security and safety for the people and the surroundings. With this feature, the generator will automatically shut-down when it is going to run out of oil.
The safety feature is additional, which oversees the generators against the dangers of carbon monoxide poisoning.
Following the Environmental Regulations
The generators usually function on fossil fuels which produce toxic fumes. Diesel and gasoline generators are two standard generators producing poisonous fumes in the air. That’s why the government has imposed strict regulations to protect the environment.
Now, the generators must have an essential certification like EPA to pass as an environmentally friendly generator. Also, states have various regulations, such as California only allow usage of CARB compliant generators.
Apart from that, propane fuel generator burns more cleanly compared to gas generators and also inexpensive to run. If your power requirement is very low, you can go for solar-powered generators. You can power a camping light, stove, and phone with this generator.
Ways To Start Your Generator
Nowadays, generators are convenient to use because of a variety of features. Some generators use the additional feature to make it easier for an inexperienced user. To use the generator, you should know how to start it.
Generators usually have three different ways to start, such as automatic start, electric start, and push start. Each type is unique and offers different techniques to start. You can choose the generator as per your experience and comfort level.
Electric Start Generators
Electric start generators don’t require a pull cord. You can start the generator by pushing the button or twisting the key. After doing this, it will power the battery installed within the generator and activates it. The process is quite straightforward.
Most portable models come with an electric start feature.
What happens if you are not at home and suddenly there is a power outage? A sudden power outage can result in a short circuit at your home. That’s where automatic start generator plays a crucial role.
The generator with automatic start will start operating automatically as soon as the power is down. Thus, you don’t have to push any type of button to operate the generator. A stationary generator features an automatic start.
Pull start or Recoil Start
Pull start is used to start small-scale portable generators that come with 5 kW of power capacity. The mechanism includes a rope, spring, and molded rope reels. If you pull the recoil cord, you are proceeding to start the engine. You need to pull the cord till you feel resistance and then leave it.
If you cannot start the engine at the first attempt, try to pull the cord back again.
Proper Generator Installation Tips
To install a generator, you need to consider few essential things. First, you need to buy the right generator according to your business or home. Secondly, you need to determine the power and size that is suitable as per your needs. After that, move to the installation guide.
