Small generators set, or small genset, are mainly of four diverse types, each with characteristics suit for particular needs. These types include portable, inverter, standby, and solar hybrid generators.
Portable small gensets
Small portable generators are frequently used for power supply in places where power availability is an issue, or communal electric power is unavailable. It is ideal for outdoor parties and jobs, camping, and other activities. Small portable generators are conveniently transportable due to their relatively small size and light weight. They operate on gasoline or propane as fuel to generate electricity.
Inverter small gensets
Inverter generators produce stable, distort-free power. This makes them ideal for powering sensitive electronic equipment like computers and smartphones. Unlike the traditional small portable generators, inverter gensets provide electricity with fluctuating frequencies. They employ rectifiers and inverters to ensure consistency, irrespective of changing motor speeds. In addition, they are quieter and more fuel-efficient, earning them power utilities in remote locations and outdoor activities.
Standby small gensets
Standby generators switch on automatically during power outages and provide power to essential home electrical equipment and lighting. They are permanently installed and connected to the home power system. They come in various sizes and run on liquid propane, natural gas, or diesel. Automatic operation makes them ideal for people who don't want the inconvenience of a power outage.
Solar hybrid small gensets
Solar hybrid generators use the sun to generate clean energy, coupled with a diesel or petrol backup as a supplementary source. They are environmentally friendly and suitable for areas with good solar illumination. They are then used to charge batteries that store the solar energy for later use in case the weather conditions are unfavorable for generation.
Portable generators are manufactured using many materials to ensure functionality and reliability. Durability is also an essential consideration, especially for equipment used in industrial operations or remote locations. Conveniently, small portable generators are made from the following materials.
Steel frames and casings
Steel is a strong and widely used material in constructing small portable generator frames. Steel used in construction ensures high strength and durability. Thus, the steel frames guarantee the genset can resist impact, vibration, and adverse weather conditions. In addition, many small gensets have a powder-coated finish to enhance resistance to rust and corrosion. This is typically mounted on rubber or shock-absorbing pads to lessen the impact on the generator and preserve the internal components.
Aluminum alloy components
Generators' casings, fuel tanks, and some structural components may be constructed from aluminum alloy due to its lightweight and resistance to rust. The aluminum helps reduce genset portability without sacrificing longevity. Aluminum alloys are usually used in generators intended for use in humid or seabed environments. The alloy comes with non-corrosive properties that keeps the machine well protected.
Engine materials
The engines of small gensets are constructed of materials like cast iron, steel, and aluminum alloys. These materials are critical as the metals provide strength, wear resistance, and thermal conductivity. Many modern inverter generators also use ceramic-coated components or advanced materials to enhance performance and lifespan.
Electrical components
Generators have copper winding and electrical components. Copper is an excellent conductor and is rarely affected by electrical resistance. Thus, copper is ideal for induction motors. Coppers coils have great electrical conductivity. This means they can easily and efficiently transmit electric current. Additionally, the electrical components are often insulated with premium-quality polymers or rubber to resist extreme temperatures and potential wear.
Plastics and composites
Small portable generators have many plastic or composite components, such as control panel covers and protective casing. Since these components do not carry heavy loads, they are manufactured from relatively cheap plastic or composites. Thus, it is light and does not add significantly to the overall weight of the generator. However, as long as it is reasonably good quality, it will protect the internal components from dirt, dust, and water.
The materials used in making small generators have a profound impact on their sustainability, performance, and portability. This makes them ideal for diverse applications.
As an electricity supply solution, portable power generators, including industrial generators, have numerous commercial uses. They provide critical light and power in situations where conventional power sources are unavailable or unreliable. The following are common small portable generators applications.
Construction and remote work sites
Small portable generators are commonly used in construction sites and remote work locations. This is because they provide the energy that tools, lighting, and work equipment need. This makes gensets extremely useful for building operations conducted in places far from the electrical grid. Construction companies tend to buy industrial generators in bulk to secure cost savings.
Outdoor events and entertainment
Small portable generators are ideal for outdoor festivals, concerts, corporate activations, and exhibitions. Gensets help power sound, lighting, and video systems and provide guests with food and beverage service and ticketing and entrance control systems. They are also perfect for fairs, markets, or pop-up activities, as they allow power supply without the need for electric lines installation.
Emergency backup power in commercial operations
Small standby generators automatically start off as backup power supply when the main power supply fails in enterprises such as retail outlets, supermarkets, and offices. This guarantees that essential systems, including computers, telecommunications, and security systems, continue to operate. Companies with standby generators frequently purchase them in bulk and can connect them to fuel supplies for efficient operation.
Agriculture and farming
Small portable generators power electric fences, water pumps, and other farming equipment, especially in areas where electrical supply is unavailable. They are also useful during harvesting or planting when farming out the electricity demand is relatively high.
Travel and tourism industries
Small portable gensets are beneficial in the tourism industry because they help power camping trailers and portable accommodation units. They ensure that travelers on camping trips have access to power for lighting, cooking, and electronic device recharging. Small gensets are also ideal for the hospitality business for camping, where guests can do activities away from the grid.
Following the relevant key factors, large quantities of small generators can be acquired at reasonable prices from reliable suppliers or manufacturers.
Power capacity
The first consideration when selecting a small portable generator is power capacity. Buyers must determine the wattage requirements of items they intend to power. These may include power tools, lighting systems, and electronic devices. Make sure to consider starting and running wattage. Some appliances require higher initial power to work, while others do not. Choose a generator that can cover power needs to prevent it from overloading.
Fuel efficiency and type
The fuel type used affects small generators' operational costs and efficiency. Gasoline, propane, and diesel are common fuels used. Diesel generators are ideal for heavy-duty activities, although they are generally more expensive and less portable. Propane fuel is less commonly used and cheaper than gasoline. Since gasoline is easily accessible and cheap, many small portable generators use gasoline. Always consider fuel efficiency. It will affect the long-term operational costs.
Portability and ruggedness
Buyers need to assess the small generator portability. Check out the size and weight of the generator. Also, check the handles and wheels. A wheeled generator will be easy to transport, increasing its portability further. At this point, think of the terrain and conditions where the generator will most likely be used. Portable generators manufactured with heavy-duty housing can perform long journeys and extreme conditions.
Noise levels and community regulations
The noise level is particularly important when selecting a small generator for outdoor shows, camps, or constructions. Noise levels differ significantly between gasoline, diesel, and inverter generators. Although inverter generators are noiseless compared to their counterparts, they produce power that can potentially save lives through its quality. Avoid generators with high decibel outputs when working in quiet or residential areas. Always ensure compliance with local noise and emission regulations.
Maintenance and support
It is vital to consider the maintenance needs of potential generator sets. Some generators require more frequent oil changes than others. Maintenance requirements are less for generators with automatic oil change features. Which manufacturer or brand does the generator belong to? Does the manufacturer offer readily available spares and after-sale support? These factors can significantly affect the generator's work in good condition and how long it lasts.
