What should I pay attention to when choosing a home generator set?

Step 1: Determine the power of the electrical equipment, if the power of the electrical equipment is 300kw, then it is not possible to choose a 300kw generator, because a starting current should also be considered. When the electrical equipment is started, it is necessary to overcome the inertia to do work, and the starting current is generally 2-7 times of the actual current.

Step 2: Choose the diesel engine brand of the generator, know the starting current to determine how big the generator to use, and the performance indicators of the generator, the diesel engine accounts for a considerable proportion, because the power of the generator is the diesel engine, the diesel engine is full of power, easy to maintain, and the failure rate is low.

Step 3: The age of the generator, the age of the generator is clearly the cumulative running time, the generator is different from other machines, if it is used as a standby machine, it may not run for ten or eight years. If it is used as a long-lasting power supply, it is 24 hours of continuous operation.

The service life of the diesel engine is generally relatively long, and the machine that has been running continuously for 5 years is still no problem, but there is a big difference between a new machine and an old machine in terms of failure rate, fuel consumption, noise, exhaust emissions, etc., so try to choose a relatively new machine.

Household generators must be easy to operate.

Because most of the home users are not very professional and too complicated, many families will not be able to operate, unlike engineering, factory generators are operated by professionals. If it is not operated properly, there may be some safety accidents. Therefore, household generators must be simple and practical, only in this way can there be a broader market.

Household generators should be small in size, low noise, light in weight and so on.

Household generators must be low noise, because household generators are used in residential areas or relatively quiet places, and generators can not affect individuals and can not disturb people. Household generators generally have to be used as mobile power sources when traveling, so small size and light weight are also necessary.

Clause.

1. Household generators look at noise

Since it is for domestic use, you need to see if the noise will affect the neighborhood life when choosing a micro generator or household generator. In general, the seller will show you the performance of the generator in advance, and a good household generator can achieve about 80% noise reduction.

Clause.

Second, ** to choose moderate

The difference in power between brands and brands is also different, and then the difference between household micro generators is very obvious.

At this time, many consumers are interested in the most inexpensive household generators, which are very likely to be shoddy. This has a great relationship with the chaos of the domestic generator market, which makes the household generator market turbid. Therefore, most of the current household generators are proportional to the quality, and the purchase of household generators needs to be moderate.

Volkswagen AG and a German energy company plan to collaborate on a small household generator powered by natural gas. What makes this small home generator special is its energy efficiency of up to 94%.

Volkswagen AG and Lichtblick Energy Co. plan to work together to produce and sell small household generators that can be placed in the basement of a home. This type of home generator uses natural gas to generate electricity and works similarly to a natural gas car engine.

In addition to meeting the electricity needs of households, this small household generator can also feed excess electricity into the public grid. The heat generated during the power generation process can be used to heat the home.

The most important parameters for choosing a generator are: voltage, frequency, and power.

The voltage and frequency can be determined to be AC 220V, 50Hz. Power, which requires you to give the exact value of each appliance, which can be obtained from the nameplate of the appliance.

The following is an estimated value for power calculation, if it does not match yours, it can be corrected based on the actual value.

Lighting power: refrigerator (1 set):

Aquarium (5): heating rod) + water pump, air pump) = 1kw 1 hp refrigeration and air conditioner (1):

473-inch LED TV (1pc):

50 liter bath heater (1 pc.): 2kw

The above total power, because the generator is best to work at 80% of the load rate when running, so a single-phase 220V, 50Hz, generator can be selected.

High-power generators are generally diesel generators. Gasoline generators have a power range from kilowatts to 10 kilowatts. Diesel generators have a power range from 10 kW to 2000 kW and even 5000 kW.

Low-power generators are generally used at home. Kilowatt generators, such as those that are portable, can be used for lighting in the field. As long as you have a 3-horsepower air conditioner at home, you need at least a 15-kilowatt generator.

Some small businesses, for lighting and other purposes, can choose 15-30 kilowatt generators. If it is a hospital, large industry and other users, then it is necessary to choose a higher power generator according to the substation capacity of their transformer.

Buying things is nothing more than looking at the cost performance, whether the performance of the items within the ** range that you can accept can meet your needs, and the performance can be referred to in the parameters, such as power generation, use conditions, indoor or outdoor use, noise size, power generation mode, energy conversion efficiency, environmental protection or whether harmful gases will be produced, roughly these conditions, to see if these can meet your requirements, in fact, the most important thing is to see what you do, such as the household you said, Whether this household is used as a backup power source in the event of a power outage, or whether it is ready to use this generator instead of a public power source, in this case, the amount of power generated and the conditions of use are different.

Buying a household engine, in layman's terms, is mainly based on the total power of the household, that is, the power of various household appliances is added together, and then multiplied by more than 2 times the margin, because the engine discharge has an efficiency problem, it is good to really reach 90%, that is to say, 10 kilowatt generator can output 9 kilowatts is good, plus some electrical appliances are inductive loads, such as air conditioners refrigerators, etc., the current is very large when starting, generally 3 7 times the rated current, so the choice of engine at least 2 times the margin, In this way, the machine can run safely for a long time.

Take a closer look at the questions asked.

Generator purchase tips:

The first step is to fuel gasoline diesel natural gas, pass the gasoline through your premise already natural gas generator. (Gasoline and natural gas generators work continuously for no more than 8 hours).

The second step is to calculate the power of the equipment and get the power.

The third step, the brand Rennes of Germany, Bradson of the United States, Ando of Japan, domestic Weichai, Shangchai and Changchai.

Step 4: Budget It is important to budget well, and if the budget is not enough, you can choose to rent, provided that you know when the power will go out.

In fact, this is very simple, you calculate the total power of the existing equipment and appliances, and then divide by 65%, and the result is close to the value, for example: you calculate that it is, you buy a 10kw generator, and you calculate it, but there is no 11kw generator in the place where you buy, you buy a 10kw one, I hope it will help you.

What is the total load? That is, how many watts does a bulb have? How much w is a fridge? How many watts are the fish tank and water pump? After multipliing, it's about the power you need for a generator! You can find me after you do the math.

I'm not selling generators.

It is most economical for you to add up the power of all the electrical appliances used at home to be slightly less than the rated power of the generator, but it is not too practical.

5kw gasoline engine, it's suitable...

We sell diesel generator set controllers, hope to help you.

Kaixun Corporation.

The total power should add up to 2kw, and a gasoline engine of 3 4kw will do.

You can choose it in a brand store.

Decisively use 5 kilowatt gasoline generators, practical, cheap, energy-saving, low noise.

First of all, it is necessary to know how much electrical power is needed to drive the generator set, what kind of power unit is used, diesel or gasoline.

The selection of diesel generator sets should be paid attention to:

1. The purpose of the unit. Because the diesel generator set can be used in 3 situations, such as common, standby and emergency. Therefore, the requirements for diesel generator sets for different purposes are different.

2. Load capacity. The load capacity and load change range should be selected according to different uses, and the single capacity of the diesel generator unit and the standby diesel generator set capacity should be determined.

3. The use of environmental conditions of the unit (mainly refers to altitude and climatic conditions).

4. The selection of diesel generator, the selection of generator and excitation mode, and the selection of automation function of diesel generator.

Diesel generator set is a diesel generator set fueled by diesel, which is generally composed of diesel engine, generator, control box, fuel tank, starting and control battery, protection device and other components.

When users buy diesel generators, they only pay attention to their performance, generators, energy consumption is not enough, but also to understand the selection point of diesel generator sets, in this regard, many users are confused, do not know enough about diesel generator sets, and confuse the role of main power in diesel generator sets.

There are 2 kinds of diesel generator sets with common power and standby power, the domestic power is subject to the common power, and the foreign power is subject to the standby power, and the standby power is generally larger than the commonly used power, so the domestic should pay attention to distinguish.

The relationship between the power unit kw and kva of diesel generator set: kw is the unit of power, generally 1kva=, do not confuse kva and kw when purchasing.

No matter which diesel generator set manufacturer's diesel generator set, there is no unified, and the specific unit is different depending on the brand, configuration and power of the unit (how many kw).

To know the specific information of the unit, it is necessary to understand the basic information of the unit: the brand of the unit, the configuration of the unit, the power of the unit, and whether the unit is a brushed diesel generator set or a brushless diesel generator set.

When purchasing the manufacturer's generator set, the manufacturer will give **, and then choose the right unit according to your needs!

A diesel generator is a device that converts the bioenergy of diesel into electrical energy, which can be used as a prime power source or as a backup power source.

The general power of the generator set is from 8 to 2000kw, and the diesel generator brands include Cummins generator, Perkins generator, Volvo generator, Doosan Daewoo generator, Yuchai generator, Weichai generator, Shangchai generator and other brands. Generally, diesel generators include stationary generators, mobile generators, silent generators, containerized generators and other styles.

When the owner chooses the generator set, the basis for reference is: the amount and power of the electrical equipment, the environmental requirements for the use of diesel generators, the requirements for the automation level of diesel generators, the owner's budget, etc. The generator set purchased according to the actual needs is the appropriate generator set.

So which generator set is better?

According to the requirements of generator set selection, the owner selects the appropriate generator set, and then selects the appropriate generator set manufacturer according to the production capacity, innovation ability, pre-sale, after-sales service ability and so on.

So what do owners need to pay attention to when buying generator sets?

1. The rated power of the generator set is kva and kw, but 1kw =, that is, the power of the 500kva genset is 400kw.

2, to refurbished machine or second-hand pretending to be a new machine, brand diesel engine has a unique serial number in the world, the owner bought the generator set, you can check these serial numbers on the Internet, refurbished machine or second-hand phone will definitely appear use information.

3. The generator set uses inferior or unqualified raw materials.

Shop around and visit the generator set manufacturer before deciding.

The choice of generator set manufacturers is, of course, to choose the OEM factory of a well-known diesel engine manufacturer, so that the quality and after-sales service of the unit are excellent.

Users can purchase online or visit the site, but be sure to pay attention to this.

Also pay attention to the choice of unit brand, the following introduction as a reference, normal standby or occasional use, 50-150 is recommended to use Shangchai diesel generator set, 150-300kw is recommended to use Yuchai diesel generator set, 300kw-1200kw is recommended to use Cummins diesel generator set, such a choice is the best choice combined with quality.

The configuration of the unit should be selected according to the needs of the work!

The word "generator" is not unfamiliar to everyone, especially when there is a power outage, and you want to have something more. Therefore, with the improvement of people's living standards and a higher leap forward in enjoying life, more and more families will have a backup generator at home for emergencies.

When people choose a home backup generator, the first thing you have to consider is when I need to use the generator, whether the generator can start normally and whether it can meet the needs of my equipment, in general, home generators, in some power outages, only need simple lighting, small air conditioning or TV, computer normal use, 3kw generator can be satisfied, when you need to cook, use induction cooker, microwave oven, or take a bath at night, water heater, projector or some entertainment equipment, It is necessary to choose 5kw-8kw generator according to the actual situation.

Some people think so, now that the country is developing so well and the power resources are so sufficient, the generator is just a backup, just buy one, of course. Generators, of course, are devices that will only be used when there is no electricity or when there is a shortage of electricity, but have there ever been times when you need a generator and it doesn't work or it doesn't work as you expected. So what is the point of you buying this kind of home backup generator, and, home backup generator, focusing on safety and silence is the first key, somewhere in Hubei, when using a generator at home, the whole family almost died of ** and carbon monoxide poisoning.

This is not alarmist, some small brand generator workshops will not pay attention to how you sell and how you use it, as long as they can make a profit, everything is not in the scope of their consideration.

In the choice of home backup generator, for the sake of you and your family, choose a high-quality generator manufacturer with a big brand guarantee.
