A container generator is a very practical and powerful power generation equipment solution. It is not just a generator, but a mobile power station that integrates a generator set, control system, distribution system, fuel system, silencing system, and safety protection system. Although container generator have many advantages, there are some precautions to keep in mind when using them.

I. Advantages of Container Generators
Container generators are a convenient mobile power station, offering all-weather protection, exceptional reliability, and ease of transportation and installation.

III. Advantages of Containerized Generators:
Compared with traditional open-frame generator sets, containerized generators provide a flexible power deployment solution.
1. Protection and Environmental Adaptability
All-weather operation: The standard container generator enclosure offers excellent protection for the internal generator and all auxiliary equipment against wind, rain, sand, dust, and theft. This makes it suitable for deployment in harsh environments such as coastal areas with high salt fog, arid deserts, and high-altitude cold regions.
Durable and robust: The container structure is designed to withstand rough transportation, lifting, and complex site conditions, ensuring a long service life.
2. Convenient Transportation and Quick Deployment
Meets standard transportation specifications: Container generators can easily be transported via container trucks, ships, and trains, greatly reducing logistics costs and complexity.
Plug-and-play: All internal systems of the container generator are fully integrated, installed, and tested at the factory. Once on-site, it only requires simple foundation fixing (or direct placement), fuel pipe connection, output cable connection, and exhaust duct installation to start operation, saving significant time and cost for on-site installation.
3. Excellent Overall Performance
Noise reduction: The interior of the container generator is usually lined with high-efficiency sound-absorbing materials and equipped with silencers, making its operating noise much lower than that of open-frame units.
4. High Safety and Reliability of Container Generators
Safety protection: The container structure isolates the running generator inside, preventing accidental contact. Additionally, internal integration of fire-fighting systems, explosion-proof lighting, and ventilation systems further enhances safety.

IV. Precautions for Using Container Generators in Cold Weather
The following are key precautions for using container generators in cold weather, covering the entire process from preparation, startup, operation, to shutdown, for user reference.
1. Core Preparations Before Starting the Container Generator
Diesel: Replace with low-temperature diesel such as -10#, -20#, or even -35#. It is recommended to choose diesel with a pour point at least 10°C lower than the historical lowest local temperature.
Engine oil: Replace with low-temperature, lower-viscosity antifreeze oil (e.g., 5W-40, 0W-40) to ensure good flowability in cold conditions.
Preheating the engine:
- Use a coolant heater: This is an effective method. Turn on the heater a few hours before starting to preheat the engine block and coolant, which significantly reduces starting resistance, minimizes battery drain, and reduces engine wear.
- Use an oil pan heater: If the equipment is equipped, it should also be used.
- Use an air heater: Preheat the cold air entering the container generator.
Check the battery and ensure sufficient power: Cold weather reduces battery capacity. Ensure the battery electrolyte level is normal and fully charged. If possible, keep the battery in a warm place and install it right before starting.
Check and maintain the starting battery of the container generator: Cold weather significantly reduces battery capacity. Use a battery insulation cover and check the power before starting; charge with an external charger if necessary.
2. Precautions During Startup and Operation of the Container Generator
If the generator fails to start on the first attempt, do not try to start it continuously for a long time. Wait at least 10-15 seconds between attempts to allow the starter motor to cool and avoid damage. After starting, allow the container generator to run without load or under low load for 3-5 minutes so that the oil can fully lubricate all components.
3. Shutdown Procedure
Gradually unload before shutdown: Before turning off, gradually disconnect all loads and let the generator run without load for 3-5 minutes. This helps high-temperature components like the turbocharger cool evenly and stabilizes the engine’s internal temperature.
4. Container generators stored in low-temperature environments for long periodsIf the container generator is not used for an extended period in a cold environment, additional precautions are needed:
- Drain the coolant: If antifreeze is not used, drain the engine and radiator water to prevent freezing and cracking of the engine block.
- Drain the fuel: Or completely drain the fuel system to prevent diesel from gelling or bacterial growth.

VI. Q&A on Container Generators
1. How to choose a container generator with the appropriate power?
Calculate the total load: List all the power (kW) or apparent power (kVA) of the equipment that requires electricity, taking into account the simultaneous usage factor and future expansion. It is generally recommended to choose a model with 10%-20% more capacity than the calculated total load to avoid long-term operation at full load and to provide a buffer.
2. What should be particularly noted when using a container generator in extreme cold weather?
Fuel: Use low-temperature diesel of the corresponding grade (e.g., -20#, -35#) and low-viscosity antifreeze engine oil.
Preheating is essential: Using a coolant heater and an oil pan heater is key to ensuring smooth starting.
Battery maintenance: Cold weather greatly reduces battery efficiency, so ensure sufficient charge, and use battery heating or insulation devices if necessary.
After starting: Run at no-load or low-load for a few minutes, and gradually increase the load after the unit temperature rises.
3. What are the advantages of parallel operation of container generators?
Increase capacity: Multiple units in parallel can meet higher power demands.
Redundant backup: Implement an "N + 1" system, ensuring that other units can continue to provide electricity if one fails.
Improve efficiency: Based on the load, intelligently start and stop some container generators so that the units in operation are in the high-efficiency load range, saving fuel.
Facilitate maintenance: Allows individual container generators to be serviced alternately without power interruption.

VII. Application Areas of Container Generators
1. Construction Sites: Container generators provide primary power for cranes, batching plants, lighting, office areas, etc., in newly developed areas where the grid cannot reach or power supply is unstable.
2. Highway, Railway, and Bridge Construction: Supply power to various construction machinery and equipment in remote construction sections.
3. Mining: Provide continuous electricity for mining equipment, lighting, and living facilities in remote mining areas.
4. Oil and Gas Fields: Container generators supply power for exploration, drilling, extraction, and camp operations.
5. Ports and Docks: Serve as offshore power sources for docked ships or for port expansion projects.
6. Data Centers/Server Rooms: Act as core backup power systems to start instantly during grid outages, ensuring no data loss.
7. Hospitals: Ensure continuous operation of critical areas such as operating rooms and life support systems during power outages.
8. Communication Base Stations: Ensure smooth mobile communication networks during natural disasters or power outages.
9. Large Events and Sports Competitions: Provide reliable power for opening ceremonies, concerts, and temporary venues, preventing interruptions during performances.
10. Disaster Prevention, Mitigation, and Emergency Rescue: Container generators act as power sources for emergency command, medical rescue, and temporary shelters when the grid fails after natural disasters like earthquakes, floods, or typhoons.
11. Financial Centers: Backup power for banks, stock exchanges, and other institutions to ensure secure financial transactions and data safety.
12. Commercial Buildings and Shopping Centers: Container generators serve as backup power sources for emergency lighting, elevators, and critical systems. Container generators are widely used due to their fully integrated design, all-weather capability, ease of transportation, and quick deployment, covering almost all scenarios that require independent, reliable, and mobile power sources.
