Many users like to buy low-priced products, but they don’t know that the products they actually buy when they spend less money are very different from the products they need and expect. So, today, let’s introduce what pitfalls you need to avoid when buying a generator:
1. Don’t talk about the brand grades of diesel engines and generators, control system configuration, don’t talk about after-sales service, just talk about price and delivery time. Some also use non-power station special oil engines, such as marine diesel engines and automotive diesel engines for generating sets. The terminal product of the unit-the quality of electricity (voltage and frequency) cannot be guaranteed.
2. Don’t talk about the relationship between rated power and backup power, just talk about a “power”, and sell the backup power to customers as long-term power. In fact, the reserve power = 1.1 x 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 that is 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. 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.
