Imagine that in the middle of a peak day, in the heart of a store or restaurant, the power goes out. The lights go off, payment systems stop working, and the refrigerator loses power. In just a few seconds, everything can turn into an operational nightmare. In this context, a diesel generator becomes more than just an option; it becomes an essential element to protect your business from financial and reputational losses. Whether you own a neighborhood store, an office, or a restaurant, a diesel generator ensures business continuity and guarantees that your operations will never be interrupted due to a power outage.
Why Do You Need a Diesel Generator in a Commercial Space?
Power Outage Losses Are Real and Costly
A power outage lasting only 10 minutes in a store or restaurant can mean:
- Blocked POS systems, preventing transactions;
- Dissatisfied customers leaving due to lack of services;
- Refrigeration systems shutting down, risking the deterioration of perishable products;
- Security cameras going offline, risking the safety of the commercial space.
For a supermarket, clinic, or restaurant, the impact can be even greater. It’s about direct financial losses but also customer trust, which can be severely affected. Additionally, a business that cannot operate properly during a power outage does not convey a professional image, which can reflect negatively on customer satisfaction.
Operational Continuity Means Professionalism
A well-chosen diesel generator not only ensures a continuous power supply but also sends an important message: “We are prepared!”
A quality generator that starts automatically in the event of a power failure protects essential equipment and ensures the smooth operation of your business. Some critical equipment that will continue to function includes:
- Safety lighting – essential for the safety of employees and customers;
- IT servers and internet networks – crucial for day-to-day operations;
- HVAC systems (heating, ventilation, and air conditioning) – for customer and employee comfort;
- Medical or technical equipment – for example, in hospitals or clinics.
By installing a reliable diesel generator, your business stays active, no matter the external conditions, and your customers will know they can rely on you.
What is a Diesel Generator and How Does It Work?
A diesel generator is a piece of equipment that converts mechanical energy obtained from a diesel engine into electrical energy. It consists of several essential components:
- Diesel engine – which generates the power needed to produce electricity;
- Alternator – which converts mechanical energy into electrical energy;
- Control system – which can be automatic or manual, depending on preferences;
- Fuel tank – which ensures continuous diesel supply;
- Soundproof housing – which significantly reduces noise generated, an important factor in commercial environments;
- Automation panel (ATS – Auto Transfer Switch) – which automatically starts the generator when the power goes out.
Diesel generators are known for their long-term reliability, low fuel consumption, and low maintenance costs. Additionally, they are more efficient than gasoline-powered generators, and their lifespan is significantly longer.
Which Type of Diesel Generator Suits Your Business?
At Endress Zenessis, the choice of generator depends on the specifics of your business and the size of your commercial space. Here are some examples of recommended sizes for different types of businesses:
- Small commercial space (café, pastry shop, neighborhood store): A generator of 8-20 kVA is sufficient to power lighting, POS systems, refrigerators, and routers;
- Medium-sized supermarket or pharmacy: A 30-60 kVA generator will support refrigeration equipment, IT systems, lighting, and air conditioning;
- Car showroom, medical clinic, IT offices: A generator of 80-150 kVA, with an included ATS system, will ensure operation alongside the main electric grid.
Choosing the right-sized generator is crucial to avoid overload or underperformance, which could lead to malfunctions or reduced efficiency.
Important Factors When Choosing a Diesel Generator for Your Commercial Space
Automatic Transfer Switching (ATS)
It’s vital for the generator to start automatically when the power from the grid goes out. This is ensured by the ATS (Auto Transfer Switch), a system that detects voltage loss and starts the generator within seconds. Once the power is restored from the grid, the ATS turns off the generator and switches back to the main source. Automatic switching minimizes interruptions and ensures a fast, seamless transition.
Soundproof Housing
If your business is located in an urban or commercial area where noise may be an issue, it’s essential to choose a diesel generator with soundproof housing. These generators are designed to operate without disturbing customers or employees, making them ideal for commercial environments with constant traffic.
Support and Maintenance
A generator without technical support is like a car without a mechanic. That’s why it’s important to choose a provider that offers:
- Authorized installation – to ensure the correct and efficient installation of the equipment;
- Warranty and post-warranty – to protect you from potential defects;
- Fast service and available spare parts – to avoid downtime;
- 24/7 emergency interventions – to protect your business at any time.
At Zenessis, we offer all of these services, ensuring that your generator operates at maximum capacity, even in the most difficult moments.
Case Study: Diesel Generator Installed in a Supermarket in Bucharest
