Factors to Consider When Buying a Generator
Broadly speaking, generators are available in two main categories. These include the portable and standby types. Furthermore, the inverter generators are also common. The power supply unit you choose will depend on specific factors
These generators typically provide between 7,000 to 20,000 watts of power for optimal blackout protection. Furthermore, they also provide power to your home until the power outage stops. The standby generators are also installed professionally, and they might draw their power from an existing line.
These generators might also require some form of professional installation. The number of circuits to which a generator can supply power and the number of devices that can run are essential. They relate to the capacity of the machine. The standby generators also have a fully enclosed design, which provides optimal protection outdoors.
While these generators provide ease of mobility, particularly during outdoor activities such as tailgating, they are often limited in power. Before investing in a portable generator, evaluate the runtime, wattage, physical size, and more. Furthermore, assess the ergonomic design features such as handle construction.
The inverter generators are famous for combining high-end power supply features and an ultra-clean power for your devices. However, such benefits come at a significant performance tradeoff. For instance, these generators are typically higher priced than their counterparts. In most cases, these generators typically range significantly in their power categories averaging between 800 to 3000 watts.
The Ultimate Guide to Buy the Right Generator
If you depend on your generator for medical purposes at home or even in the event of a power outage in your home, then choosing a suitable machine is imperative. The consumer market is packed with many generators for domestic and large scale applications. Such a range of machine differences might make it seem challenging to choose a reliable machine brand. However, the process is easy, and you have to consider a few key parameters.
Determine Your Needs
Since whole house generators are suitable for both industrial and domestic applications, it's crucial that you determine your needs first. To be specific, you have to identify the particular way in which you expect to use the generator for your needs.
It is vital that you determine the type of load that you need to run because this will, in turn, determine the wattage level that you require. Any issues that might lead to overloading the generator might easily lead to failure and damage the performance of the appliance.
More importantly, just in the same way as your car can’t run at full speed all day, the same also applies for generators. Most appliances might require a large current level during startup, and this referred to as a surge. Therefore, your generator must have sufficient spare capacity to cope with the demand for power.
Generators can run and operate on many different types of fuel. It is vital that you also determine the type of fuel that your generator will run to help estimate the cost. The types of fuel are many and wide-ranging. The common ones include diesel, LPG, diesel, and more.
LPG – Liquid propane generators are often integrated to the primary electric house panel. You may have to consider getting this type of generator if you want a standby or portable generator. These brands of generators are affordable and straightforward to operate. Furthermore, they are also popular because they produce a small amount of emissions.
Diesel – the diesel generators are popular for their immense power and fuel efficiency. However, such benefits come at a significant tradeoff. The diesel generators produce high amounts of emissions, and they also require regular maintenance.
Petrol – petrol generators produce a small amount of emissions and are only suitable for commercial applications. On average, these generators have power ratings that average between 1 to 15 KVA. Petrol produces clean power, and it is also an affordable source of energy.
The type of load you want to run on the machine also plays a significant role in your choice of generator. For instance, you either have to choose a generator to power devices such as sensitive electronic equipment.
These are the generators that produce low levels of harmonic distortion during operation. Usually, the inverter generators are best for this type of power supply purpose. However, if you want to run large machines such as fridges, welding machines or more, then you might have to consider a higher capacity machine.
The electrical use of the generator is also another critical factor to consider. For instance, a portable generator is suitable for basic power supply applications, but it cannot power a whole house.
Usually, these generators average in between 1 KW to 15KW and are ideal for small electrical machines. These include powering tools such as lights, grinders, fans, and saws. These machines are suitable for home improvement or construction projects where you need a fast and convenient energy supply.
However, the whole house backup generator is an excellent solution for many different types of electrical usages. Otherwise referred to as standby generators, these units can supply power that averages in the hundreds of KWs.
Backup Power Using a Transfer Switch
A transfer switch is also installed in the generator. The manual transfer switch lets you switch from utility power to back up with just a simple flip of a switch. Furthermore, the device is easy to use, but you might have to locate the button to activate the feature.
The Automatic Transfer Switch (ATS) will automatically sense where there is a power issue, and it will turn on automatically. Once you restore the power, the machine will switch back on, and the generator will shut off.
You might also have to determine the specific amount of power you might require for your appliances. The amount of power watts are often specified on the electrical equipment that you use.
Some devices might have additional starting watts levels that you might have to combine with the overall watt level. You can find the starting watts by multiplying the specific watts of the device by 3. The following are some of the appliances and their specific watts to give you a basic idea of the concept. However, you might have to evaluate the power requirements specifically. They include:
Toaster – 1050 – 1500 Watts
Vacuum cleaner – 1000 – 3000 Watts
2 HP Motor - 7500 (starting watts) and 2500 (operational watts)
1 HP Motor - 3500 (starting watts) and 2500 (operational watts)
Fridge or Cooler - 700 - 1200 (starting watts)
Other Important Features
If you are still not sure about your preferred generator brand, then you can still several other key factors. Among some of these factors include:
- The power quality – the generator should provide high quality power that has minimal harmonic distortion for smooth device operation. Producing small amounts of distortion ensures your devices get quality power without any power surge or over voltage issues.
- Generator operation – the machine should also be able to run at lower RPM for a few minutes, thereby making it efficient and silent in operation. Any loud sounds over the 75DB level are considered as noise.
- Mobile monitoring – the generator should also let you evaluate the status of your machine from anywhere conveniently. These include monitoring the machine by using a PC, tablet, or even a smartphone. You should also be able to easily access the information such as the operating status and the maintenance schedule.
- Engine performance – the engine should be purpose build and well-lubricated to be capable of handling the rigors of use. This way, the generator can provide reliable power and minimal amounts of maintenance.
- User-friendly controls – the generator should also have a multilingual LCD that lets you monitor that amount of power. Also, it should allow you to track the maintenance and status intervals to ensure the machine operates in top conditions.
- Design construction – you should also be keen to invest in a machine that has a sturdy design exterior for long-lasting performance. Even more, the generator should be appealing to let you address your power supply issues in style.
In the broad view of things, keeping your home or property free from power outages depends on your ability to make informed investments. The consumer market has many different brands and designs of power supply solutions. The best whole house generator is perfect for supplying your property with a reliable supply of clean power.
While these generators are typically large in size, you can use them to power fridges, hairdryers, microwaves, cookers and more. More importantly, they start up automatically and require minimal maintenance as well.
