When purchasing diesel generator sets, customers are often confused as to which diesel generator set is very important. lfitis too large, it will increase the cost, and ifitis too small, it cannot meet the electricity requirements. Here are some suggestions for you:

1.Choose the right power:

1. Ordinary electrical appliances: such as computers, TVs, electric ligts, ligting lamps, add up according to the rated power = total power consumption;

2. Heating appliances: microwave ovens, water heaters, water heaters, induction cookers, etc. The power of these appliances is calculated as 1.5-2 times the total power consumption;

3.Inductive appliances: air conditioners, water pumps, refrigerators, air compressors, motors, etc. The power is calculated at 2.5-3 times the rated power = total power consumption.

2. Avoid three misunderstandings:

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 1KVA=0. 8KW. Imported units are generally expressed in KVA, while domestic electrical equipment is generally expressed in KW. Therefore, when calculating power, KVA should be converted into KW by a 20% discount.

2. Confuse the relationship between rated power and maximum power, just say "power", and sell the maximum power as rated power to customers. In fact, the maximum power- 1.1 x rated power. Moreover, the maximum power can only be used for 1 hour in 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 2 10% of generator power because of mechanical loss. Worse sill, 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, so that the unit life is reduced, maintenance is frequent, and the use cost is high.
