In telecommunications, a single power outage can mean the difference between guaranteed uptime and a wave of complaints. When networks must stay operational 24/7 under all conditions, power solutions become the foundation of silence—that calm in which everything works perfectly, even when the electrical grid fails.
This is where diesel generators come into play. Not just any generator, but one that can start automatically, withstand extreme temperatures, properly power sensitive equipment, and ideally be monitored remotely. In a word: a generator designed for telecom, not just “adapted.”
Why Do You Need a Special Generator for Telecom?
Not every generator can support a telecommunications network. Sensitive equipment, continuous power supply, extended autonomy, and the need for remote monitoring mean that traditional solutions just aren’t enough. Here’s why telecom generators must meet the following:
- Automatic start when voltage drops (via ATS panel)
- Compatibility with UPS systems and redundancy
- Soundproofing and compact housing for urban areas or limited spaces
- 24/7 reliability in extreme conditions, including low temperatures, dust, or humidity
- Remote control and monitoring for managing distributed fleets
- Low emissions, especially in residential or regulated areas
Zenessis offers three distinct product lines that meet these requirements, each with a clear role depending on your infrastructure’s complexity and location.
The Zenessis Diesel Range: 3 Solutions for Diverse Telecom Needs
1. 🔹 Stationary Diesel Generators (Zenessis Classic Series)
Power range: 9 to 2500 kVA
These are the base models, ideal for fixed stations, communication nodes, and technical centers. Powered by engines such as Perkins, Doosan, Iveco, Scania, or Volvo, they stand out with:
- High reliability at competitive costs
- Enclosed and soundproof versions for city or rooftop applications
- Easy integration with ATS panels and UPS
Perfect for: telecom operators with fixed infrastructure, metropolitan coverage, switching centers.
2. 🔹 Stage III Diesel Generators – Controlled Emissions for Critical Applications
Power range: 30 to 800 kVA, depending on engine
These generators comply with industrial emissions regulations, making them excellent for semi-urban and rural areas. Features include:
- Clean combustion technologies, especially with Baudouin, Volvo, or Iveco engines
- Advanced control systems compatible with telecom applications
- Ideal for clients seeking a balance between efficiency, durability, and legal compliance
Recommended for: mobile stations, temporary 5G networks, areas with moderate pollution regulations.
3. 🔹 Stage V Diesel Generators – Maximum Performance, Minimum Emissions
Power range: 18 to 650 kVA
These are the most advanced diesel generators in the Zenessis portfolio, compliant with Stage V—the strictest European emissions standards. Ideal for telecom infrastructure in:
- Dense urban centers where noise and emissions must be strictly controlled
- Projects with strict environmental requirements
- Shared infrastructure among multiple operators, where certifications are essential
Equipped with smart sensors, digital control, remote monitoring, and fully soundproofed enclosures.
Essential Factors in Choosing a Diesel Generator for Telecommunications
Choosing a diesel generator isn’t just about “how much power it provides.” In telecom, where outages mean coverage loss, performance must be backed by reliability, control, and efficiency. Key considerations include:
1. Rated Power and Autonomy
- Estimate the actual consumption of equipment on-site (base station, server racks, transmission devices, etc.).
- Choose a generator that provides at least 20% more than peak estimated load.
- Check autonomy at an average load of 70–80%. Zenessis generators offer extended autonomy, and models can be equipped with additional tanks.
2. Automatic Start System (ATS Panel)
Manual intervention is not an option in telecom. That’s why ATS panels are critical: they instantly detect power failure and automatically start the generator. Switching back is just as fast.
Zenessis manufactures its own ATS panels, fully integrated with its systems, available as:
- Fully automatic
- Smart (with remote management)
- With prioritization between multiple sources
3. Emissions and Environmental Standards
Depending on the location, you may need a generator that meets Stage III or Stage V emissions standards.
- Rural or industrial areas often allow classic or Stage III generators
- In cities, on buildings, or in sensitive zones, Stage V standards are essential—this is where Zenessis ranges with Kubota, Volvo, Doosan, and Iveco Stage V engines come into play.
4. Soundproofing and Footprint
Telecom often means small spaces and public exposure: rooftops, containers, shared enclosures.
- Zenessis soundproof enclosures significantly reduce noise levels (below 70 dB at 7m)
- Generators available in open frame, soundproof, or super soundproof versions.
5. Remote Monitoring and Control
Efficiently managing a telecom network with hundreds of locations requires automation.
- Zenessis generators can be delivered with GSM/WiFi modems and LCD digital control modules.
- You have access to: fuel level, runtime, temperature, errors, event logs, etc.
- Systems are compatible with Zenessis’s proprietary telematics solutions for full integration
6. Reliability and Low Maintenance
- Built with Cummins, Perkins, Doosan, Volvo, or Kubota industrial engines
- Long service intervals, and parts are quickly available via the Zenessis network
- Lifespan? Over 20,000 operating hours under optimal conditions
