Eight misunderstandings that customers can easily generate when purchasing diesel generator sets
1. Confusing the relationship between KVA and KW to use KVA as KW to exaggerate power and sell it to customers. In fact, KVA is the apparent power, KW is the effective power, and the relationship between them is IKVA=0.8KW. Imported units generally use KVA to represent power units, while domestic power equipment is generally indicated by KW. Therefore, when calculating power, KVA should be converted into KW by 8 fold.
2. Do not talk about the relationship between long-term (rated) power and backup power. Just say "power" and sell backup power to customers as long-term power. In fact, backup power = 1.1x long line power. Moreover, the backup power can only be used for 1 hour in 12 hours of continuous operation.
3. The power of the diesel engine is as large as the power of the generator to reduce the cost. In fact, the industry generally stipulates that diesel engine power ≥ generator power is 10% because of mechanical losses. Even worse, some diesel engine horsepower is misreported to the user as kilowatts, and the diesel engine is used to configure the unit. It is commonly known as: small horse-drawn cart, and the unit life is reduced, maintenance is frequent, and the use fee is No high.
4. The second mobile phone refurbished machine is sold to the customer as a brand new machine, and the refurbished diesel engine is equipped with a new generator and control cabinet, so that the general non-professional users can't tell whether it is a new machine or an old machine.
5. Only report the diesel engine or generator brand, do not report to the place of production, do not report the unit brand. Such as Cummins in the United States, Volvo in the United Kingdom, and Steinford in the United Kingdom. In fact, it is impossible for any diesel generator set to be completed independently by a single company. Customers should fully understand the diesel engine, generator, control cabinet manufacturer and brand of the unit in order to comprehensively evaluate the grade of the unit.
6. Sell the unit without protection function (commonly known as four protections) as a fully functional unit to the customer. What's more, sell the unit with incomplete meter and no air switch to the customer. In fact, the industry generally requires more than 10KW units must be equipped with full instrument (commonly known as five meters) and air switches; large units and automation units must have self-protection.
7. Do not talk about the brand grade of diesel engine and generator, the configuration of control system, not to mention after-sales service, blindly talk about price and delivery time. Some will also use non-power station special oil engines, such as: marine diesel engines, and vehicle diesel engines for generator sets. The quality of the end product of the unit - electricity (voltage and frequency) cannot be guaranteed. Units with too low prices generally have problems, commonly known as: only buy the wrong and not sell wrong!
8. Do not talk about random accessories, such as with no silencer, fuel tank, oil pipeline, what grade battery, large capacity battery, several batteries and so on. In fact, these attachments are important and must be stated in the contract. What's more, even the water tank fan is not included, allowing customers to open the pool.
