In today’s world, ensuring a reliable power supply is essential for both residential and commercial properties. As a contractor, providing our clients with a backup generator solution not only enhances your home’s resilience but also adds value to your property. This guide will help you navigate the process of selecting, installing, and maintaining backup generators, ensuring a smooth experience for you and your home.
Selecting the Right Backup Generator
1. Assess Power Needs
Begin by evaluating the power requirements of your property. This includes identifying essential appliances and systems that must remain operational during an outage, such as:
-Refrigerators
-Heating and cooling systems
-Medical equipment
-Sump pumps
-Lights
(You can easily check wattage of these systems by googling "what wattage does (insert model number of system/appliance) need?"
Create a load list to determine the total wattage required. Remember to consider starting watts, which are higher for certain appliances.
2. Choose the Generator Type
There are two main types of backup generators:
-Portable Generators: Best for smaller power needs, portable generators can be moved and stored easily. They require manual setup and refueling.

-Standby Generators: These are permanently installed and automatically switch on during an outage. They typically offer greater capacity and convenience, making them suitable for homes with higher power demands.

3. Consider Fuel Source
Backup generators can run on various fuel types, including gasoline, propane, and natural gas. Discuss the options, considering availability, cost, and storage requirements.
4. Assess Noise Levels
Noise can be a significant concern, especially in residential areas. Look for models that have noise-reduction features or are designed to operate quietly.
5. Check Local Regulations
Ensure compliance with local codes and regulations regarding generator installation, including zoning laws, noise ordinances, and safety standards.
Installing the Backup Generator
1. Obtain Necessary Permits
Before installation, obtain any required permits from local authorities. This step ensures compliance with regulations and helps avoid potential fines or issues down the line.
2. Choose the Installation Location
Select an appropriate location for the generator that meets safety guidelines, such as:
-A minimum distance from windows, doors, and air intakes
-Adequate ventilation to prevent carbon monoxide buildup
-Accessibility for maintenance and refueling
3. Electrical Connections
For standby generators, coordinate with a licensed contractor/electrician to handle the electrical connections. Ensure proper wiring and a transfer switch installation to safely switch between grid power and generator power.
4. Fuel Supply Installation
If the generator requires a dedicated fuel supply, ensure the correct installation of propane tanks or natural gas lines, adhering to safety codes.
5. Testing
Once installed, conduct thorough testing of the generator to ensure it operates as expected. Run a full load test to confirm it can handle the home's power needs.
Maintaining the Backup Generator
1. Schedule Regular Maintenance
Establish a routine maintenance schedule to keep the generator in peak condition. This should include:
-Regular oil changes
-Checking and replacing air filters
-Inspecting fuel systems
-Testing the battery and connections
2. Conduct Monthly Tests
Perform monthly tests on your generator to ensure it starts and operates properly. This is particularly important for standby generators that may sit idle for extended periods.
3. Keep the Area Clean
Keep the area around the generator clear of debris, leaves, and other obstructions to ensure proper ventilation and operation.
4. Prepare for Seasonal Changes
In colder climates, ensure that the generator is prepared for winter. This may include using winter-grade fuel and ensuring proper lubrication.
5. Keep Records
Keep detailed records of maintenance, tests, and any repairs. This documentation can be beneficial for warranty claims and future maintenance.
