Frequently Asked Questions
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 biodiesel?
Biodiesel is renewable fuel from vegetable oils or animal fats. B20 compatible with most diesel engines. B100 requires engine modifications.
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 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 wet stacking?
Wet stacking occurs when diesel engines run at <30% load for extended periods, causing unburned fuel accumulation. Prevention: load bank testing at 75%+ load monthly.
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 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.
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 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 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 generator derating?
Derating reduces output for environmental conditions. Altitude: -1% per 100m above 1000m. Temperature: -1% per 10°C above 25°C.
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 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 IP rating?
IP (Ingress Protection) indicates enclosure protection. IP44: spray water. IP54: dust protected. IP65: dust tight + water jets. Generator enclosures typically IP44-IP65.
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.
