Outevo Silent Generator Power Ranges: Parameters, Fuel Consumption, Protection, and Selection Guide

Silent generators, also known as low-noise generator sets, are power generation equipment designed with specialized noise reduction technologies to minimize operating sound. They are widely used in scenarios with strict noise requirements, such as hospitals, data centers, residential areas, and commercial complexes. Below is a detailed breakdown of silent generators across three power ranges, along with key selection guidelines.

Small Power Range: 0-100 kW

Typical Parameters: Rated voltage 230V/400V (single/three-phase), frequency 50Hz/60Hz, noise level 60-75 dB(A) at 7 meters, equipped with built-in 8-hour daily fuel tank and automatic voltage regulator (AVR).

Fuel Consumption: Approximately 210-230 g/kWh under 75% load. Light load (below 30%) increases fuel consumption by over 20% due to incomplete combustion.

Protection Measures: Low oil pressure shutdown, overload protection, short circuit protection, high water temperature alarm, and leakage protection.

Usage Scenarios: Home emergency backup, small shops, camping sites, communication base stations, and small construction sites.

Power Stability: Voltage regulation accuracy ≤±1%, suitable for powering precision electronic devices such as computers and medical instruments.

Medium Power Range: 100-300 kW

Typical Parameters: Rated voltage 400V/480V (three-phase), 6-cylinder water-cooled turbocharged engine, noise level 65-79 dB(A) at 7 meters, supports ATS (Automatic Transfer Switch) for automatic switchover within 15 seconds.

Fuel Consumption: Approximately 205-220 g/kWh under full load. For example, a 100 kW unit consumes about 20.5 liters of diesel per hour at full load.

Protection Measures: In addition to basic protections, includes phase sequence protection, grounding protection, and remote monitoring module (GPRS/4G) for real-time parameter tracking.

Usage Scenarios: Medium-sized factories, hotels, schools, community hospitals, sewage treatment plants, and urban construction projects.

Power Stability: Steady-state frequency adjustment rate ≤5%, transient voltage adjustment rate ≤+20%, capable of handling impact loads such as motor startups.

Large Power Range: 300 kW and Above

Typical Parameters: Rated voltage 400V/11kV (medium voltage optional), containerized structure, noise level 75-85 dB(A) at 7 meters, supports multi-unit parallel operation and intelligent cloud platform monitoring.

Fuel Consumption: Approximately 200-215 g/kWh under full load. For example, a 300 kW unit consumes about 61.5 kg of diesel per hour at full load.

Protection Measures: Full relay protection configuration including longitudinal differential protection, stator grounding protection, negative sequence overcurrent protection, and overexcitation protection.

Usage Scenarios: Data centers, large manufacturing workshops, port shore power, industrial park microgrids, and municipal emergency power supply.

Power Stability: Equipped with AVR and synchronous controllers, voltage fluctuation range ≤±0.5%, suitable for continuous operation of high-precision equipment.
