Huu Toan will advise you on how to buy a home generator that suits your needs through the article below.

1. Reasons to buy a generator

Most of us buy generators for backup purposes. Because at any time, unexpected situations can happen such as unexpected power failure, electrical wiring, short circuit or natural disaster, storm, flood, etc.

  • In the family: equipping a generator is the best way to maintain a normal state of life. For example, the food in the refrigerator will be preserved stably, not damaged because of a power failure. Air conditioners and fans continue to cool all members on hot summer days. In particular, in the case of natural disasters, storms, and floods, backup power from the generator are really necessary for life safety, ensuring communication,...
  • For the production business, it is even more necessary for generators: Every hour and every minute of production stoppage will greatly affect sales and profits, so don't let the power be cut off suddenly. The larger the size of the business, the more the corresponding number of backup generators is required. Although the purchase of industrial explosives is expensive in the beginning, in the long run, it will have great benefits for the business, ensuring the stability of the production business without stagnation.

2. Classification of generators

How to distinguish different types of generators, let's learn through some of the following criteria:

2.1 Classification of generators by fuel used

Gasoline generator

Gasoline generators are mainly used in households or small businesses or for occasional living purposes. The machine has specific advantages and disadvantages:

  • Pros: Simple design, compact, and easy to operate. Simple starting, relatively low cost, pleasant noise, and vibration.
  • Cons: High operating costs because gasoline prices are higher than oil. Fuel consumption is also higher.

Oil generator

Oil generators are chosen when we have a need to consume a large amount of electricity at constructions, factories, large production, hospitals, apartments, ... because it can save fuel and transportation costs. low practice.

  • Pros: Low fuel consumption, less likely to cause explosions and breakdowns. Save on maintenance costs. Long lifespan.
  • Cons: The price of the machine is relatively high, the noise is quite loud. The pollution rate is higher than the gasoline engines. The design is quite bulky. Hard to move.

2.2 Classification of generators according to the number of phases

1 phase generator

  • Pros: Compact design, easy to move. Low price. Smooth operation, low noise. Can supply power for most single-phase equipment
  • Cons: Does not provide enough power if using many large power devices at the same time.

3 phase generator

  • Pros: Provides large capacity power on most devices. Powerful motor, stable operation, can operate continuously for a long time.
  • Cons: Large size, heavyweight, bulky, a bit difficult to transport. The selling price is relatively large. The way of transportation, maintenance, and repair is relatively complicated.

Based on the pros and cons of each, you can choose a single-phase or three-phase generator to suit your needs. If the single-phase load is too large, but the single-phase generator cannot be loaded, it is necessary to use a 3-phase machine, and then take the source of each phase to supply the 1-phase load.

2.3 Classification of generators by purpose and scale of use

Residential generators

Residential generators are generators with small capacities (under 10kva). Specialized in household activities and small and medium-sized production and business activities.

  • Pros: Mobility, easy to move. Reasonable price. Smooth operation
  • Cons: It is necessary to study the appropriate load because the capacity of residential generators is not large.

Industrial generators

Industrial generators are generators with large capacities (greater than 10kva). Specialized used in production workshops, industrial parks, hospitals, schools, large buildings ...

  • Pros: Stable operation, fuel-saving, long life, long-term use, environmentally friendly.
  • Cons: Large initial investment cost, not high mobility.

3. Types of generators available on the market

Currently, there are many generator brands on the market, including domestic and foreign brands:

- Domestic brand

Brand (origin) is one of the important factors to help evaluate the quality of generators.

A very great point that customers in Vietnam need to know is that most generator manufacturers in Vietnam choose very rigorously the input materials that make up the product. From the engine, generator head, to each bolt, nut...

Some well-known engine manufacturers are often used by domestic brands such as Yanmar, Volvo, FPT, MTU, Kohler, etc.

Some major generator brands in the country have factories meeting international standards: powder coating systems, modern machines, supporting robots…

Therefore, you can rest assured to choose a domestic brand with the same quality as G7's generator.

Moreover, large domestic manufacturers often have nationwide warranty stations with a strong team of engineers and technicians. This is a huge advantage in terms of after-sales service of these brands compared to foreign brands.

- Foreign brands

Foreign engine brands that are of interest to Vietnamese people can be mentioned as Cummins of the US, Perkins of the UK, Doosan of Korea,...

In terms of component structure, generators imported 100% from abroad are not too different from those produced and assembled in the country. However, because it is a machine from big brands in the world and the import price is quite high, you have to spend a larger amount of money to own a complete imported machine. Moreover, a worrying problem is that imported goods are difficult to guarantee in terms of warranty, maintenance, and repair because there is no suitable technical expert team.

In recent years, the proportion of imported goods has tended to decrease and domestic products have increased gradually because of the advantage of price and service warranty. Therefore, domestic generator brands, such as having more support to improve quality and service, to serve the needs of all customers.
