1. Understanding Home Generators
A home generator, also known as a standby generator or backup generator, is a device that provides electricity during power outages or when the primary power source fails.
It serves as a reliable backup power supply so essential appliances and systems in your home continue to function smoothly.
Types of Home Generators
Portable generators: These versatile units can be moved around and used in various locations. They typically run on gasoline, propane, or diesel fuel and are ideal for powering small appliances and tools or providing temporary electricity during emergencies. However, they may be unable to power an entire household for an extended period.
Standby generators: Standby generators are permanently installed outside the home and are connected directly to the electrical system. They are designed to automatically start within seconds of detecting a power outage and can provide backup power to the entire house. Standby generators are usually fueled by natural gas, propane, or diesel and can run for prolonged durations, making them a top choice for long-term power outages.
Home generators operate by converting mechanical energy into electrical energy. They consist of an engine fueled by gasoline, propane, natural gas, or diesel and an alternator that generates electricity.
When the main power supply fails, the generator’s automatic transfer switch senses the outage and signals the generator to start. The engine then powers the alternator, producing an electrical current fed into the home’s electrical panel.
Once the main power is restored, the transfer switch automatically switches the power source back to the utility grid and shuts off the generator.
Understanding how home generators function is important for choosing the right type and size for your needs.
2. Determining Your Power Needs
Before selecting a home generator, it’s critical to determine your household’s power requirements during an outage.
Wattage refers to the amount of power an electrical device consumes, while voltage represents the force or pressure of electricity flowing through a circuit. When choosing a generator, match its wattage output to the combined wattage requirements of your appliances.
List all the appliances and devices needing power, including lights, refrigerators, HVAC systems, electronics, and medical equipment. Then, calculate the wattage requirements for each item to estimate the total power needed. The wattage information is on the appliance labels or in the user manuals.
Once you have the total wattage, consider the starting (surge) wattage and running (continuous) wattage for each appliance to ensure your generator can handle the initial power surge when devices are turned on.
Additionally, make sure that the generator’s voltage output matches the voltage requirements of your home’s electrical system (typically 120/240 volts for residential use).
Failure to match the wattage and voltage requirements may damage appliances.
Assessing essential vs. non-essential appliances
During a power outage, it’s important to prioritize which appliances and systems are essential for maintaining safety, comfort, and functionality in your home.
Essential appliances may include refrigerators, freezers, heating or cooling systems, sump pumps, medical devices, and lighting. Non-essential appliances, such as televisions, gaming consoles, and entertainment systems, can be powered off to conserve generator fuel and prioritize power needs.
Understanding your power requirements is crucial for selecting the right home generator size and type for a reliable backup power supply during emergencies.
3. Choosing the Right Generator
There are a few factors to consider when selecting a generator.
Fuel type: Different generators run on various fuel types, such as gasoline, propane, diesel, or natural gas. Consider availability, cost, and storage requirements when selecting the fuel type that best fits your needs.
Power output: Determine the total wattage needed to power essential appliances and systems during an outage. Ensure the generator you choose has adequate power output to handle the combined wattage of these appliances.
Run time: Evaluate the generator’s run time on a single fuel tank. A longer run time means fewer interruptions for refueling during power outages.
Noise level: Generators can produce varying levels of noise during operation. Consider the generator’s noise level, especially if you live in a noise-sensitive area or prefer a quieter environment.
Size and portability: Based on your specific requirements, determine whether you need a portable or standby generator. Portable generators offer flexibility and mobility but may require manual operation and refueling. Standby generators provide automatic backup power and are typically larger and permanently installed.
K&K Supply has many generator options to suit your needs. Here are some of our recommended options for your home power needs.
By carefully considering the above factors, you can select a generator that meets your power needs, budget, and preferences.
4. Installation and Maintenance
Let’s discuss important factors for installing and maintaining your generator.
First, you’ll want to select the right location for installing the generator, preferably outdoors in a well-ventilated area. Keep the generator away from doors, windows, and vents to prevent exhaust gasses from entering your home.
It’s important to make sure there’s adequate clearance around the generator for ventilation and maintenance access.
Next, let’s review basic maintenance requirements:
Regular inspections: Schedule inspections of the generator, fuel lines, and electrical connections to identify any signs of wear, damage, or corrosion. Check the battery status and fuel quality regularly. Address any issues promptly to prevent further damage or malfunctions.
Oil changes and filter replacements: Follow the manufacturer’s recommended maintenance schedule for changing the oil, air filter, and fuel filter. Regular oil changes are essential for maintaining engine performance and longevity. Clean or replace air and fuel filters to ensure proper airflow and fuel delivery to the engine.
Troubleshooting: Common issues may include engine failure to start, low output voltage, or excessive noise. If these problems occur, perform basic troubleshooting steps, such as checking fuel levels, inspecting spark plugs, and verifying electrical connections.
Your home generator will run smoothly if you follow basic installation protocols and maintenance requirements.
5. Safety Precautions
A generator is a powerhouse, but with this power comes responsibility.
Check out our safety guidelines below to prevent problems.
Carbon monoxide prevention: We mentioned this in the previous section, but it’s so important we’ll repeat it: Never operate a generator indoors or in enclosed spaces, as it can lead to carbon monoxide poisoning. Always place the generator outdoors in a well-ventilated area, away from doors, windows, and vents.
Electrical safety: Avoid overloading the generator by connecting only essential appliances directly to the generator or through heavy-duty extension cords rated for outdoor use. The generator and all electrical connections should be dry to prevent electrical hazards. Follow proper grounding procedures to minimize the risk of electric shock.
Fuel storage and handling: Store fuel in approved containers in a well-ventilated area away from heat sources, sparks, or open flames. Keep fuel containers tightly sealed to prevent spills or leaks.
Local regulations and codes: Familiarize yourself with local regulations, zoning laws, and building codes for the installation, operation, and maintenance of home generators. Obtain necessary permits and approvals from local authorities before installing the generator to ensure compliance with safety standards and avoid potential fines.
