A standby generator has many parts that work together. It gives backup power without you doing anything. The system knows when the power is out and starts right away.
Main components include:
Engine-generator set: The engine makes the generator create electricity.
Automatic transfer switch: This part knows when power is out and switches your building to generator power.
Battery system: The battery helps start the engine fast.
Control panel: It checks the system and runs tests.
Fuel system: The generator uses diesel or natural gas stored at your building.
Cooling and lubrication systems: These help the engine run well.
Enclosure: It keeps the generator safe from weather.
When the power goes out, the automatic transfer switch disconnects your building from the grid. The generator engine starts and gets to full speed in 10 to 30 seconds. The switch then connects your building to the generator. Power comes back to your lights, machines, and safety systems in less than a minute. When the power returns, the switch moves your building back to the grid and turns off the generator. This keeps your business safe and stops power from going back to the utility lines.
Component | Function |
|---|---|
Engine-Generator Set | Makes backup electricity |
Transfer Switch | Changes power source automatically |
Battery System | Starts the engine |
Control Panel | Checks and controls the system |
Fuel System | Gives fuel to the engine |
Cooling/Lubrication | Stops overheating and lowers friction |
Enclosure | Protects from weather |
A standby generator helps you worry less. You know your business will keep working, even if the power goes out.
The automatic transfer switch (ATS) is the main part of your standby generator system. It watches your building’s power all the time. When the ATS notices a power outage, it quickly starts the generator. It gets your building ready for backup power. Here is how the ATS works in a business:
The ATS checks your utility power all the time.
If it finds an outage, it sends a signal to the generator’s control system.
The generator turns on and gets to the right voltage.
The ATS moves your building’s power from the utility to the generator.
When the utility power comes back, the ATS waits a bit, then switches power back to the grid.
The ATS can run tests and follow schedules to keep your system ready.
This happens in just seconds. You do not have to do anything. The ATS keeps your business safe and working during outages.
You need the right size standby generator for your building. Power capacity depends on what your building needs. Most commercial generators are between 100 kW and over 300 kW. This works for offices and factories.
Power Capacity Range | Typical Applications |
|---|---|
100 kW to 200 kW | Industrial sites, large offices, places with many machines and HVAC systems |
200 kW to 300+ kW | Tall buildings, factories, heavy machines, elevators, escalators |
To pick the right size, add up the power needs of your equipment. You can check peak usage, look at utility bills, and use wattage guides for your business. Always plan for growth and follow safety rules.
Tip: The right generator size keeps your business running and protects your money.
You can pick from different fuel types for your standby generator. Each type has its own good points.
Diesel: Reliable, easy to store, safe, and good for long use.
Natural Gas: Clean, steady supply, no refueling, and works well in cold weather.
Propane: Quiet, clean, stores well, and fits remote places.
Bi-Fuel: Uses both diesel and natural gas for more options and longer use.
Fuel Type | Advantages | Best Use Case |
|---|---|---|
Natural Gas | Steady supply, low cost, no need to store on-site, cleaner emissions | Cities or suburbs with gas lines |
Propane | Efficient, flexible, clean, stores for a long time | Rural or far away places without gas lines |
Diesel | High efficiency, reliable, handles big power needs | Important places needing long use |
Bi-Fuel | Saves money, flexible fuel, switches automatically | Businesses needing longer use |
Big commercial standby generators cost $10,000 to $25,000 or more. Installation cost depends on the size and setup of your system. You need experts to install and take care of it. Most systems need service every six months or after 400 hours of use. Regular checks keep your generator ready and your business safe.
You get peace of mind, keep important things working, and follow safety rules when you buy a good standby generator.
You might wonder how a standby generator is different from a portable generator. The biggest differences are in how they work and what they can power. The table below shows how each one compares:
Criteria | Standby Generators | Portable Generators |
|---|---|---|
Activation | Automatic start during outage | Manual start by user |
Integration | Built-in automatic transfer switch | No transfer switch |
Power Capacity | High (10,000–50,000+ watts) | Lower (1,000–10,000 watts) |
Installation | Permanent, professional setup | Mobile, no installation needed |
Fuel Type | Natural gas or propane, continuous supply | Gasoline or diesel, manual refueling |
Application Areas | Whole business, critical systems | Small businesses, homes, outdoor events |
User Intervention | Not required | Required |
Shutdown | Automatic | Manual |
A standby generator stays outside your building. It connects to your power system. When the power goes out, it starts by itself. You do not have to do anything. It can run for many days if it has enough fuel. A portable generator is smaller and easy to move. You must start it yourself and plug in your devices. It only runs for a few hours before you need to add more fuel.
Note: Standby generators are best for businesses that need power all the time. Portable generators are good for short jobs or when you need to move them.
Both types of generators have good and bad points. You need to pick what works best for you.
Standby Generators:

Pick a standby generator if you want backup power for your whole business. Choose a portable generator if you need a fast, easy fix for small jobs or short power outages.
You want your business to keep working, even if the power fails. A home standby generator or a whole-house generator gives you peace of mind. These systems turn on by themselves. They keep your lights, computers, and safety systems running. You do not have to worry about losing data or stopping work.
A generator that is taken care of can run for many days. Some commercial models work for 72 hours without stopping. Studies show that with good care, a generator has an 80% chance to work for two weeks during a long outage. If you do not take care of it, that chance drops by half.
A generator also helps keep your workplace safe. It powers emergency lights, air flow, and climate control. This helps you follow safety rules and keeps people safe. OSHA says you must have emergency lights and working air systems during outages. You also need to make sure your generator has good airflow. It makes fumes that can be dangerous if not handled right.
Tip: Regular checks and good airflow help keep your team safe and your business open.
You need to plan for the cost to install a home standby generator. Most commercial systems cost between $10,000 and $25,000, depending on size and features. The process takes one to four weeks.
