1. Confusing the relationship between KVA and KW. Treat KVA as KW exaggerated power and sell it to customers. In fact, KVA is the apparent power, and KW is the effective power. The relationship between them is IKVA=0.8KW. Imported units generally use KVA to indicate the power unit, while domestic electrical equipment generally uses KW, so when calculating the power, KVA should be converted into KW with a 20% discount.
2. Don’t talk about the relationship between long-term (rated) power and reserve power, just talk about a “power”, and sell the reserve power to customers as long-term power. In fact, reserve power = 1.1x long-travel power. Moreover, the backup power can only be used for 1 hour during 12 hours of continuous operation.
3. The power of the diesel engine is the same as the power of the generator, in order to reduce the cost. In fact, the industry generally stipulates that diesel engine power ≥ 10% of generator power because of mechanical loss. Worse still, some people misreport the horsepower of the diesel engine as kilowatts to the user, and use a diesel engine less than the generator power to configure the unit, commonly known as: small horse-drawn cart, and even the life of the unit is reduced, maintenance is frequent, and the use cost is high. High.
4. Sell the refurbished second mobile phone as a brand-new machine to customers, and some refurbished diesel engines are equipped with brand-new generators and control cabinets, so that ordinary non-professional users cannot tell whether it is a new machine or an old one.
5. Only the diesel engine or generator brand will be reported, not the place of origin, nor the unit brand. In fact, no diesel generator set can be completed independently by a single company. Customers should fully understand the manufacturer and brand of the diesel engine, generator, and control cabinet of the unit in order to comprehensively evaluate the grade of the unit.
