When buying a generator or ordering a rental generator, don't try to buy a machine that's too big for your needs. A good rule of thumb is to make sure the generator is always loaded to at least 50% of its rated power. If you're shopping for diesel generators, they have a huge range of options, from low to high power. Guangxi Dingbo Generator Set Manufacturing Co.,Ltd. supplies 30KW-KW automatic, automatic switching remote monitoring, mute and mobile diesel generator sets of various specifications.

Today, in the generator industry, there are many different types of engines that serve basically the same purpose. For example, natural gas generators, gasoline generators, and diesel generators are all similar in power and function, but use different fuels. Although there are many kinds of fuels, they do the same thing as keeping energy flowing. Diesel generators convert mechanical energy into electrical energy, which can be used to drive any device that requires electricity. An industrial diesel generator consists of 7 internal core components: Internal combustion engine: The mechanical energy input by the internal combustion engine. The engine is diesel powered.
Diesel generator ratings are fine as long as the KW and KVA are kept below their ratings. The recommended power should not be lower than the rated PF due to the low efficiency of the generator. Ultimately, exceeding the kW rating or the kVA rating will damage the device.
Because you know what to consider when shopping for the right generator power, don't overlook the importance of regular generator maintenance. Although industrial diesel generators are designed to last a long time, the key to getting the most out of your system is maintenance. The chamber of commerce recommends regular maintenance, such as after several months or hours of continuous operation. More frequent maintenance may be necessary, depending on frequency of use and environmental conditions.
The first thing to do is to calculate the total power requirement. To do this, prepare a list of equipment, lighting and other electrical equipment that must be powered by a backup generator in the event of a power outage.
When purchasing a generator set, you should consider the genset purpose, performance, loading capacity & variation range, and automation. The detailed information are as follows'
1. Purpose: Diesel generator set is usually divided into three types including standby, commonly used and emergency diesel generator set. The requirement is different for different purposes.
2. Loading capacity: You should choose loading capacity and variation range according to the different uses so as to determine the genset capacity and standby capacity.
3. Automatic function: Whether it can be fulfiled with the mains automatic switch during a power failure.
Avoid the traps when purchasing a diesel generator set.

1. Avoid the price is lower than the market when buying a diesel generator set. In general, the low price units have problems more or less. Be alert whether it is a refurbished genset.
2. Specify the generator with accessories in the contract, such as tank, oil pipe, and storage battery (battery specification, capacity and quantity), etc.
3. Avoid purchasing the diesel genset (Commonly known as four protection) without protection. When buying, check whether the genset instrument is comprehensive and the units equip with a air switch or not. Besides, avoid buying such diesel engine which power is lower than the alternator for the unit configuration. Diesel engine power is equal or higher 10% than the generator power in the industry due to the mechanical loss.
4. Confusion relationship between KVA and KW. Take KVA as KW and exaggerate the power to sell to customers. Actually, KVA refers to apparent power, KW refers to the effective power. The relationship between them is 1KVA=0.8KW. Usually, imported units are expressed by KVA and the domestic electric equipments are expressed by KW. However, the bad manufacturers usually take standby power as normal power to sell to customers. They just talk about one power and ignore the relationship between normal power and standby power. Actually, standby power = 1.1 normal (Rated) power. Moreover, standby power can only be used for 1 hour in continuous operation for 12 hours. When you are going to buy a diesel generator set, you should inquire the salesman and know the generator unit is expressed by KVA or KW.
What should consider before buying?
1. Before buying, be clear what power you want to buy, what size you want to buy, the diesel generator set you want to buy is for industrial or home use, and what brand of generator set you wnat to buy, etc.
2. Inquire the salesman whether the diesel generator set is made by manufacturer not from the brokers or distributors. This is quite important since some bad manufacturers pretend to be genuine manufacturers and sale the diesel generators to customers. So it is necessary to go to their factory to observe and study, check whether it is real.
3. Besides, it is important to know about the warranty duration. In general, the warranty typically ranges from one year to five years depending on the generator set type. The warranty for residential and industrial genset is different.
4. Whatever types of generator set you are going to buy, you should know about the brand and history of the generator set. For example, Cummins, Volvo, Perkins, etc. Any diesel generator set can't be independently accomplished by an enterprise. Only by having a comprehensive understanding of the genset including diesel engine, generator, control cabinet and brand, can you evaluate the unit level synthetically.
Indeed, there are many factors you should consider when buying a diesel generator set. The above important factors are provided by Jiangsu Starlight Electricity Equipments Co.,Ltd.
