FAQ
What equipment can a 20kW generator power?
It can power air conditioners, water pumps, lighting systems, office equipment, and small-scale industrial machinery.
Do your generators support Automatic Transfer Switch (ATS) systems?
Yes. We offer ATS systems to enable automatic backup operation.
Which generator brand is the best?
Cummins and Perkins are widely popular for their exceptional reliability, while Weichai and Ricardo represent excellent value-for-money options.
Can a generator run continuously?
Yes. Industrial-grade models can operate continuously for extended periods, provided they undergo proper maintenance.
What is the exact fuel consumption rate of a 20kW diesel generator set at various load levels?
Fuel consumption is directly correlated with the specific engine model installed and the current electrical demand. For a standard 20kW diesel generator equipped with a premium-brand engine, the average fuel consumption at a typical 75% operating load is between 4.8 and 5.4 liters per hour. At a continuous 100% load, fuel consumption is approximately 6.5 to 7.2 liters per hour. Detailed fuel consumption curves specific to a particular configuration can be obtained from our engineering department.
Can a 30kW generator set easily handle the starting load of direct-drive induction motors?
Yes, provided that the starting surge current does not exceed the generator’s standby capacity (kVA). A standard 30kW (37.5 kVA) generator set—equipped with an advanced brushless alternator and a reliable Automatic Voltage Regulator (AVR)—can withstand instantaneous surge currents of up to 300% of its rated capacity for durations of up to 10 seconds. For applications involving high-power motors or air compressors, we recommend selecting a generator featuring a Permanent Magnet Generator (PMG) excitation circuit configuration to maximize surge-handling capability.
What are the specific installation requirements for integrating an Automatic Transfer Switch (ATS) with a 15kW silent generator?
Our 15kW silent generators feature an integrated digital control system and come pre-fitted with dedicated terminals for ATS communication wiring. During installation, a multi-core signal control cable must be routed alongside the main power conduit, connecting the generator’s terminal box to the external ATS panel. When the main grid voltage drops below a preset threshold (typically 90% of the rated voltage), the controller initiates a 3-to-5-second delay cycle to automatically start the engine, synchronize the voltage phase, and signal the internal contactor to safely switch the load.
What standard maintenance schedules must 10–30 kW industrial generators adhere to in order to maintain operational compliance?
To ensure warranty validity and optimal field performance, please follow the structured maintenance program outlined below:
• Break-in Period Maintenance: Perform the initial engine oil and primary filter change after 50 hours of field operation.
• Routine Maintenance: Conduct a comprehensive inspection every 250 to 500 operating hours or every 6 months. This includes replacing the lubricating oil, renewing the primary fuel filter, and testing the integrity of the air intake filter.
• Annual Parameter Check: Flush the engine cooling system, verify the alternator winding resistance, and perform a clean load test to remove internal carbon deposits.
