How To Choose The Right Diesel Generator

Jun. 25, 2022

Customers who consult us every day are often confused about how much diesel generator set to choose when purchasing diesel generator sets? Indeed, when purchasing a diesel generator set, the power selection of the diesel generator set is very critical. Too large selection increases the cost, and too small selection cannot meet the electricity requirements. So how should you choose? Here Jiangsu Starlight Electricity Equipments Co.,Ltd. provides you with the following suggestions:

 

I. Select the appropriate power: (adjusted according to the actual situation)

 

1. Ordinary electrical appliances: such as computers, TVs, lamps, and lighting lamps, add up according to the rated power = total power consumption.

 

2. Heating electrical appliances: microwave ovens, water heaters, water boilers, induction cookers, etc. The power of such electrical appliances is calculated by 1.5-2 times = total power consumption.

 

3. Inductive electrical 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.

Remarks: The power of diesel generator sets is generally selected by the number and total power of electrical equipment. The power of the generator is not simply the sum of the power of all electrical equipment, and the starting method of the electrical equipment also needs to be considered. The general start-up methods are divided into direct start, step-down start or soft start. Therefore, in addition to the sum of all electrical powers, the starting power of each electrical appliance should also be considered when selecting the power of the generator set.

 

II. Avoid three misunderstandings:

1. Confuse the relationship between KVA and KW. Treat KVA as KW to exaggerate power and sell it to customers. Actually KVA is apparent power, KW is 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, so when calculating power, KVA should be converted into KW at a 20% discount.

 

2. Confuse the relationship between rated power and maximum power, only say one "power", and sell the maximum power as rated power to customers. In fact, maximum power = 1.1x rated power. Also, maximum power can only be used for 1 hour out of 12 hours of continuous operation.

 

3. The power of the diesel engine is configured as much as the power of the generator in order to reduce the cost. In fact, the industry generally stipulates that the power of the diesel engine is greater than or equal to 10% of the power of the generator, because of mechanical losses. Even worse, some misreport the horsepower of the diesel engine as kilowatts to the user, and configure the unit with a diesel engine less than the power of the generator. Commonly known as: small horse-drawn cart, and even the life of the unit is reduced, maintenance is frequent, and the usage fee is high.
