During the purchase process of diesel generator sets, due to lack of understanding, the purchased generator sets not only cost a lot but also have poor quality. For inexperienced customers, Meihua generator manufacturers provide the following suggestions on how to choose generator sets:

1、 Check to see if it is a second mobile phone refurbishment machine. Some businesses sell the second mobile phone refurbishment machine to customers as a brand new one, and some also equip the refurbished diesel generator with a brand new generator and control cabinet, making it difficult for users who have not had contact with it to distinguish whether it is a new or old machine. When purchasing, it is necessary to distinguish it to avoid buying a refurbished machine.

2、 Confusing the relationship between KVA and KW. Exaggerate the power of KVA as KW and sell it to customers. The actual KW is the effective power, and the relationship between them is 1KVA=0.8KW. Imported units generally use KVA as the unit of power, while domestic electrical equipment generally uses KW as the unit of power. Therefore, when calculating power, KVA should be discounted by 80% to convert it into KW.

3、 The power of the diesel generator set is configured to be the same as the power of the generator in order to reduce costs. In fact, it is generally stipulated in the industry that the power of diesel generators is ≥ 10% of the generator power due to mechanical losses. Some businesses also mistakenly report the horsepower of diesel generators to users as kilowatts, and use diesel generators with power lower than the generator to configure the unit.

4、 Only report the diesel generator or generator brand, not the production location or brand. For example, Cummins in the United States and Volvo in Sweden. In fact, it is impossible for any diesel generator set to be independently completed by a single enterprise. Customers should have a comprehensive understanding of the manufacturer and brand of the diesel generator, generator, and control cabinet of the unit in order to comprehensively evaluate the level of the unit.

5、 The relationship between rated power and backup power is only one 'power', and the backup power is sold to customers as long-term power. In fact, backup power=1.1x long travel power. Moreover, the backup power can only be used for 1 hour during 12 hours of continuous operation.

6、 Learn about random accessories, including or without fuel tanks and pipelines, what brand of batteries to bring, what capacity of batteries, how many batteries to bring, and more. In fact, these attachments are very important and must be clearly stated in the contract. Even the water tank fan is not included, allowing customers to purchase it later on.

7、 Don't talk about the brand grade, control system configuration, and after-sales service of diesel generators and generators, just talk about price and delivery time. Once this type of machine is sold, the manufacturer cannot be contacted, and the quality of the machine can only be left to chance.

8、 Some businesses sell units without protective functions to customers as fully functional units, and some even sell units with incomplete instruments and no air switches to customers. In fact, the industry generally stipulates that units with a power output of 10KW or above must be equipped with full instruments and air switches; Large units and automation units must have four protection functions. Therefore, when choosing, it is necessary to understand these four protections clearly.

As an important backup power generation equipment after a power outage, it provides electricity for the production and manufacturing of enterprises, so it must be purchased at the time of purchase
