FAQs
What does “consistent performance” mean for an electrical generator, and how is it measured?
Consistent performance refers to a generator’s ability to deliver the rated voltage and frequency within narrow tolerances across its entire operating range. It is measured by monitoring voltage regulation (typically ±1–2%), frequency deviation (±0.5 Hz on a 50 Hz set or ±0.6 Hz on a 60 Hz set), harmonic distortion (THD below 5%), and load acceptance/rejection times. Independent factory testing and on-site commissioning reports document these metrics so you know the unit will run critical loads without flicker, shutdowns, or equipment damage.
What types of generators do you supply, and which one should I choose for my application?
We stock diesel, natural-gas, and dual-fuel generators ranging from 10 kW portable units to 2 MW containerised systems. For prime power in remote areas, diesel remains the most robust option. Natural-gas sets excel in urban standby roles where lower emissions and quieter operation are priorities. Dual-fuel models switch seamlessly between fuels, offering resilience during supply disruptions. To choose the best set, consider load profile (kW/kVA), duty cycle (standby, prime, or continuous), site fuel availability, emission regulations, and expansion plans. Our application engineers provide free sizing and ROI analyses.
How do your generators maintain stable voltage and frequency when loads fluctuate?
Each unit uses an AVR (Automatic Voltage Regulator) paired with digital governors. The AVR senses millisecond-level changes in output voltage and adjusts excitation current to keep voltage constant. The electronic governor monitors shaft speed via a magnetic pickup and modulates fuel injection to hold frequency steady. In addition, our premium models incorporate PMG (Permanent Magnet Generator) excitation, which supplies a clean, independent power source to the AVR, further improving transient response under large motor starts or sudden load drops.
What routine maintenance is required to keep my generator performing reliably over the long term?
Routine maintenance falls into daily, monthly, quarterly, and annual tasks. Daily: visual inspection for leaks and a quick panel check of oil pressure and temperature. Monthly: run the set for 15–30 min under load, record voltage/frequency, and top up coolant and fuel. Quarterly (250 h): change lube oil and filters, clean air filters, and inspect belts and hoses. Annually (or 1,000 h): change fuel filters, flush coolant, test the battery, and perform a load-bank test to 80 % of rated capacity. Following the OEM service schedule and using genuine parts can extend engine life beyond 20,000 h.
Are your generators compliant with current emission, noise, and safety standards?
Yes. All models meet or exceed EPA Tier 3/Tier 4 (USA) and Stage V (EU) emission limits, and we supply certificates upon request. Sound-attenuated enclosures reduce noise to as low as 65 dB(A) at 7 m, satisfying most municipal ordinances. Safety features include NFPA 110-compliant emergency stop, overspeed shutdown, high-temperature and low-oil-pressure sensors, and full CE/UL listings where applicable. We can also supply spark-arrested mufflers, explosion-proof components, or custom skid bases for hazardous-area installations.
What after-sales support and warranty coverage do you provide?
All generators carry a standard 2-year/2,000-hour comprehensive warranty covering parts and labour. Extended 5-year coverage and planned-maintenance contracts are available. Our 24/7 technical hotline connects you to factory-trained technicians who can troubleshoot most issues remotely. For on-site emergencies, we guarantee a qualified engineer will be dispatched within 24 hours in the continental US and 48 hours worldwide. We also maintain regional parts depots and offer operator training, remote monitoring kits, and upgrade paths for fuel system or paralleling controls.
