Definition
A soundproof generator (canopy/silent type) uses an acoustically engineered enclosure to reduce noise levels. Typical noise: 65-75 dBA at 7 meters (vs 95-105 dBA for open sets). Methods: acoustic insulation (rockwool/foam, 50-100mm), silencer/residential-grade muffler, anti-vibration mounts, air intake/exhaust silencers. Critical for urban, hospital, and residential installations.

Frequently Asked Questions
What is a turbocharger?
A turbocharger uses exhaust gas energy to compress intake air, increasing engine power density 30-50%. Critical for modern high-output diesel engines.
What is biodiesel?
Biodiesel is renewable fuel from vegetable oils or animal fats. B20 compatible with most diesel engines. B100 requires engine modifications.
What is a transfer switch (ATS)?
An ATS automatically switches load between utility and generator. Types: open transition, closed transition (make-before-break), soft-loading. NFPA 110 requires <10 sec transfer.
What is Modbus?
Modbus is an open serial protocol (RS-485) for generator controller integration. RTU mode: registers map to generator parameters. Supported by most controllers.
What is a brushless exciter?
Brushless excitation eliminates brushes/slip rings using rotating rectifiers. Benefits: no brush maintenance, no carbon dust, explosion-proof — standard in modern generators.
What is a standby generator rating?
Standby rating: maximum power for emergency use, 200-250 hours/year max, no overload. Typical for backup applications. Also called Emergency Standby Power (ESP).
What is a diesel generator?
A diesel generator converts the chemical energy in diesel fuel into electrical energy. It consists of a diesel engine (prime mover) and an alternator (generator) mounted on a common base frame.
What is the difference between kW and kVA?
kW (kilowatt) = real power consumed. kVA = apparent power. kW = kVA x Power Factor. Standard PF is 0.8: 100 kVA = 80 kW.
What is common rail injection?
Common rail maintains constant high fuel pressure (up to 2500 bar) with electronically controlled injectors. Benefits: precise timing, better atomization, lower emissions, 5-8% fuel savings.
What is AVR in a generator?
AVR (Automatic Voltage Regulator) maintains generator output voltage within ±1% by controlling exciter field current. Modern digital AVRs offer soft start, voltage matching, and Modbus communication.
What is NFPA 110?
NFPA 110 is the US standard for emergency and standby power systems. Level 1: life safety (hospitals, high-rise). Level 2: less critical. Defines transfer time, testing, and maintenance.
What is ISO 8528?
ISO 8528 is the international standard for reciprocating internal combustion engine driven AC generating sets. Defines ratings, performance, testing, and documentation requirements.
What is genset paralleling?
Paralleling connects multiple generators to a common bus to increase capacity, improve reliability (N+1), and enable maintenance without shutdown. Requires synchronization and load sharing.
What is a containerized generator?
A containerized generator is a complete genset housed in an ISO shipping container (20ft or 40ft). Provides weatherproof, transportable, plug-and-play power solution.
What is synchronizing?
Synchronization matches voltage, frequency, phase angle, and phase sequence before connecting a generator to a live bus. Auto-synchronizers control speed and voltage automatically.
