frequently asked questions
frequently asked questions
Can open generators be used outdoors?
Yes. They can operate outdoors but must be placed in a dry, well-ventilated area and protected from rain, snow, and extreme weather. Using a canopy or shelter is recommended for extended outdoor use.
Can I connect multiple devices to an open generator?
Yes, as long as the total load does not exceed the generator’s rated capacity. Always check the combined power requirements to prevent overload.
Are open generators suitable for residential use?
Yes. They are effective for backup power during outages, but their higher noise levels may not suit areas with noise restrictions. Placing the generator away from living spaces can help reduce disturbance.
What maintenance is required for open generators?
Regularly check oil levels, clean or replace air filters, monitor fuel lines, and keep the battery charged. Change oil and filters as recommended, and inspect for leaks, corrosion, or worn parts to ensure reliable performance. Finally, detailed inspection, parts replacement, and repair records are maintained.

Open generators are a versatile and reliable power solution for industrial, commercial, and large-scale residential use. Unlike silent or enclosed generators, they feature an exposed frame design that prioritizes ease of access, better ventilation, and simplified maintenance. While this design may produce more noise, it enhances cooling efficiency and makes open generators a cost-effective choice for environments where sound is less of a concern.
BISON, a leading open generation manufacturer in China, offers a range of high-performance open generators engineered for consistent power output, durability, and long-term reliability. Designed to perform in demanding conditions, these generators are ideal for powering heavy machinery, keeping businesses operational, or providing dependable backup during outages.
In this article, BISON will discuss open generators with you, from their versatility and durability to cost-effectiveness, giving you a comprehensive understanding of this type of generator to facilitate your subsequent purchase.
How to choose the right open generator for your needs
Determine your power requirements
Calculate total power demand by adding the running wattage of all equipment and including starting (surge) wattage for motors or pumps (often 1.5–2× higher). Add a 20–25% capacity margin for efficiency, safety, and future expansion. For example, a 50 kW load would need about a 62.5 kVA generator.
Choose the right fuel type
- Diesel: high fuel efficiency, longer lifespan, handles heavy loads, ideal for industrial and continuous use.
- Gasoline: lower cost, easier to source, suitable for small-scale or backup use, but less fuel-efficient.
- Dual-fuel: They operate cleaner, and gasoline or LPG offer flexible fuel options, but availability may be limited.
Assess noise levels
Be sure to check the noise regulations in your area or industry to ensure your generator complies with legal limits for noise pollution. Open generators are louder than enclosed units. During operation, consider using a soundproof enclosure, noise-reducing barriers, or placing the unit away from crowded areas to reduce noise levels.
Portability vs. fixed installation
Portable: Skid-mounted or wheeled, under 20 kVA, ideal for events, construction, or temporary backup.
Fixed: Permanently installed, 20–100 kVA+, best for continuous power in businesses or industries.
Control and monitoring features
Look for digital panels showing voltage, frequency, and fuel levels. Remote monitoring helps track performance and reduce downtime, especially for large operations.
Safety features
Choose models with automatic shut-off (for malfunctions or low oil), overload protection, and circuit breakers to protect users and equipment.
Fuel tank size
Larger tanks allow longer operation with fewer refuels. For industrial use, choose models with bigger tanks (often over 30 kVA).
Compliance with local regulations
Ensure the generator meets emission standards and safety codes to avoid fines and maintain legal operation.
Types of open generators
When selecting an open generator, consider the fuel type and required power capacity:
- Small (under 20 kVA): for light-duty tasks like small businesses or residential use.
- Medium (20–100 kVA): for commercial or industrial applications needing moderate power.
- Large (above 100 kVA): for heavy industrial use, providing reliable, continuous power.
- Industrial-scale: high-power units for large facilities or complexes, often using diesel, natural gas, or bi-fuel options.
Advantages of open generators
- Cost-effectiveness: Open generators, without soundproofing, offer a simpler design, making them more economical than enclosed generators. They also cost less to transport because of their lighter weight and compact size, making them budget-friendly for both purchase and long-term use.
- Better cooling efficiency: With no enclosure to restrict airflow, open generators allow better heat dissipation. This natural cooling helps maintain optimal operating temperatures, improving performance and extending the generator’s lifespan.
- Easy maintenance access: The open design provides quick access to components like spark plugs, filters, and the engine, making inspections, repairs, and routine maintenance faster and easier. This reduces downtime and keeps the generator running reliably.
- Simple installation: Open generators are easy to install due to their lightweight and flexible design. They can be placed in various locations without complex mounting, making them suitable for both temporary and permanent setups.
