Everything you need to know about selecting, purchasing, and maintaining diesel and gas generator sets from Jinjia Power Equipment.
To calculate the correct generator size, first list all equipment that needs power simultaneously. Add up their running wattage, then multiply motor loads by 3 to account for starting current (inrush). The total gives you the minimum kW requirement. We recommend adding 20-25% headroom for future expansion.
As a general rule: 1 kW of actual load ≈ 1.25 kVA of generator capacity. For example, if your total calculated load is 200 kW, you should select a 250 kW (313 kVA) generator set.

The best brand depends on your specific requirements:
At Jinjia Power, we integrate all major brands and can recommend the optimal choice based on your budget, application, and destination market.
Open frame generators have no sound enclosure, offering lower cost, better ventilation, and easier maintenance access. They are suitable for industrial settings, indoor installations, or construction sites where noise is not a concern.
Silent type generators feature a sound-attenuated canopy that reduces noise to 65-75 dB(A) at 7 meters — essential for hospitals, hotels, residential areas, and urban construction. Silent type units cost 15-25% more but eliminate noise complaints and meet municipal noise regulations.
kVA (kilovolt-ampere) measures apparent power, while kW (kilowatt) measures real/active power. The relationship is: kW = kVA × Power Factor (PF).
For diesel generators, the standard power factor is 0.8, meaning a 100 kVA generator delivers 80 kW of actual usable power. When selecting a generator, divide your total kW requirement by 0.8 to get the kVA rating needed.
Example: 200 kW load → 200 ÷ 0.8 = 250 kVA generator required. Always consult Jinjia Power's engineering team for accurate sizing based on your specific load profile.
Jinjia Power manufactures generator sets in all standard voltage and frequency combinations:
All units are equipped with AVR (Automatic Voltage Regulation) maintaining voltage stability within ±1%. Custom voltage configurations available upon request.
Fuel consumption depends on generator load and engine efficiency. General guidelines:
| Generator Size | Full Load (L/hr) | 75% Load (L/hr) |
|---|---|---|
| 100 kW | 20-26 L/hr | 10-15 L/hr |
| 300 kW | 60-78 L/hr | 35-50 L/hr |
| 500 kW | 100-130 L/hr | 60-90 L/hr |
We provide detailed fuel consumption data for every model. Contact us for your specific requirements.
Our silent type (sound-attenuated) generator sets achieve noise levels of 65-75 dB(A) at 7 meters, depending on power rating:
These levels are comparable to normal conversation volume and comply with most municipal noise ordinances. Our canopy design uses multi-layer acoustic insulation with high-density sound-absorbing materials.
