Frequently Asked Questions
What is the difference between diesel generator sets and gasoline generators
Diesel generator sets offer a broader power range (from 7kW to over 2500kW), higher fuel energy density, and lower operating costs, making them suitable for long-duration continuous operation. Gasoline generators are typically smaller in power (generally below 10kW), easier to start, and relatively quieter, suitable for short-term emergency use. For industrial and commercial applications, diesel generator sets represent a more economical and reliable choice.
How to determine the required generator set power capacity
First, calculate the power consumption of all simultaneously operating electrical equipment. Distinguish between resistive loads (such as lighting and heating equipment, calculated at rated power) and inductive loads (such as motors and air conditioners, which require consideration of starting current, typically 3 to 5 times the rated power). After summing all equipment power, add 20% to 30% margin to obtain the recommended generator set rated power. Yangzhou Kangcheng Power Equipment Co., Ltd. can provide professional power calculation and selection consultation services.
What is the noise level of silent generator sets
Silent generator sets significantly reduce operating noise through soundproof enclosures, mufflers, and noise reduction materials. At a distance of 7 meters from the unit, noise levels can typically be controlled below 75 decibels, with some optimized designs achieving approximately 65 decibels. Specific values depend on unit power, engine type, and soundproofing design. It is recommended to request third-party test reports from the manufacturer before purchase.
Can multiple generator sets operate in parallel
Yes. Multiple generator sets can achieve synchronous parallel operation through parallel cabinets to jointly share the load or provide redundant backup. Parallel operation requires consistent voltage, frequency, phase, and phase sequence, along with dedicated parallel control systems. Yangzhou Kangcheng Power Equipment Co., Ltd. can provide parallel operation solution design and supporting equipment for customers.
Does a household backup generator require an automatic transfer switch
An Automatic Transfer Switch (ATS) is strongly recommended. When grid power fails, the ATS automatically starts the generator and switches the load to generator power once stable; when grid power returns, the ATS automatically transfers the load back to grid power and stops the generator. The entire process requires no manual intervention, making it particularly suitable for unmanned or nighttime outage scenarios. For residential users, ATS is an important configuration for enhancing power reliability.
How to estimate fuel consumption of generator sets
Diesel generator set fuel consumption rates vary by engine brand and power, generally approximately 200 to 250 grams of diesel per kilowatt-hour. For a 100kW unit operating at full load, hourly fuel consumption is approximately 20 to 25 liters of diesel. Actual consumption is affected by load factor, altitude, ambient temperature, and engine condition. It is recommended to refer to the technical parameter tables provided by the manufacturer.
