Choose the Perfect Home Standby Generator

When it comes to ensuring your home remains powered during outages, a home standby generator is a reliable and efficient solution. Unlike portable generators, home standby generators are permanently installed and automatically activate during a power loss, providing seamless electricity to your home. Selecting the perfect standby generator involves considering several key factors. This guide will help you navigate through these considerations, ensuring you choose the best generator for your needs.

1. Assessing Power Needs

The first step in choosing a home standby generator is determining your power requirements. You need to evaluate how much power your household needs during an outage.

Identify Essential Appliances: List all the essential appliances and systems you want to keep running during a power outage. This may include refrigerators, HVAC systems, lights, water heaters, sump pumps, and medical equipment.

Calculate Total Wattage: Each appliance or system has a specific wattage requirement. Identify both the starting (surge) and running (continuous) wattages. Surge wattage is typically higher because appliances require more power to start. Add up the running wattages and the highest surge wattage to get an estimate of the total power you need.

Consider Future Needs: Think about any future appliances or systems you might add to your home. It’s wise to choose a generator with a bit more capacity than your current needs to accommodate future additions.

2. Fuel Types

Home standby generators typically use one of three fuel types: natural gas, propane, or diesel. Each fuel type has its advantages and disadvantages.

Natural Gas: Natural gas is a convenient option if your home already has a natural gas line. It provides a continuous fuel supply, eliminating the need for storage. Natural gas generators are generally quieter and produce fewer emissions. However, in the event of a natural disaster, gas lines can be disrupted.

Propane: Propane is another popular fuel choice. It can be stored in large tanks on your property, providing a reliable fuel source. Propane has a long shelf life and burns cleaner than diesel. However, it requires regular refilling and can be more expensive than natural gas.

Diesel: Diesel generators are known for their durability and fuel efficiency. Diesel fuel is energy-dense, providing longer runtimes. However, diesel generators can be noisy, and diesel fuel requires proper storage and maintenance to prevent degradation.

3. Generator Size and Capacity

Choosing the right size generator is crucial to ensure it can handle your power needs without overloading. Generators are rated by kilowatts (kW), which indicates their power output.

Small (7-12 kW): Suitable for smaller homes or essential circuits, such as lights, refrigerators, and a few other critical appliances.

Medium (13-20 kW): Ideal for mid-sized homes, capable of powering more appliances and systems, including HVAC units.

Large (20+ kW): Designed for large homes or those with high power demands, capable of running multiple systems and appliances simultaneously.

Professional Assessment: Consider hiring a professional electrician or generator installer to assess your power needs and recommend the appropriate size. They can perform a detailed load analysis to ensure you choose a generator that meets your requirements.

4. Automatic Transfer Switch

An automatic transfer switch (ATS) is a critical component of a home standby generator system. It detects power outages and automatically transfers the power load to the generator. Here’s what to consider:

Load Management: ATS systems can manage the load by prioritizing essential circuits. This ensures critical appliances receive power first and prevents overloading the generator.

Size and Compatibility: Ensure the ATS is compatible with your generator and electrical system. The size of the ATS should match the capacity of the generator.

Manual vs. Automatic: While automatic transfer switches are more convenient, manual transfer switches are available at a lower cost. However, manual switches require you to start the generator and switch the power load manually.

5. Installation and Location

Proper installation and placement of your standby generator are crucial for safety and efficiency.

Professional Installation: Always hire a licensed electrician or professional installer to set up your standby generator. They will ensure the installation meets local codes and regulations and that the generator is properly connected to your home’s electrical system.

Location: Place the generator on a stable, elevated platform to prevent flooding. It should be positioned at a safe distance from windows, doors, and vents to avoid carbon monoxide poisoning. Ensure there is adequate ventilation and that the generator is protected from the elements.

Noise Considerations: Generators can be noisy, so consider installing it away from bedrooms and living areas. You can also look into soundproof enclosures to reduce noise levels.

6. Maintenance and Reliability

Regular maintenance is essential to keep your standby generator running smoothly and reliably.

Scheduled Maintenance: Follow the manufacturer’s recommended maintenance schedule, which typically includes oil changes, filter replacements, and inspections. Regular maintenance ensures the generator is ready to operate during an outage.

Professional Servicing: Consider signing up for a maintenance plan with a professional service provider. They can perform routine checks, diagnose potential issues, and ensure your generator is in top condition.

Self-Monitoring: Many modern generators come with self-monitoring systems that provide real-time alerts and diagnostics. These systems can notify you of any issues, allowing you to address them promptly.

Warranty and Support: Check the warranty provided by the manufacturer. A good warranty indicates confidence in the product’s quality. Ensure you have access to customer support and local service providers for repairs and maintenance.

7. Safety Features

Safety should be a top priority when selecting a home standby generator.

CO Detection and Shutdown: Carbon monoxide (CO) is a deadly gas produced by generators. Look for models with CO detection and automatic shutdown features to protect your household from CO poisoning.

Overload Protection: Overloading a generator can cause damage and pose safety risks. Choose a generator with built-in overload protection to automatically shut down the system if the load exceeds safe levels.

Surge Protection: Power surges can damage your appliances and electronics. Some generators come with surge protection features to safeguard your devices.

Weather-Resistant Enclosure: Ensure the generator has a weather-resistant enclosure to protect it from rain, snow, and other harsh conditions.

8. Cost and Budget

Home standby generators are a significant investment, so it’s essential to consider the costs involved.

Initial Purchase Price: The cost of the generator itself can vary widely based on size, brand, and features. Small generators may cost a few thousand dollars, while larger models can reach upwards of $10,000 or more.

Installation Costs: Professional installation can add to the overall cost. Installation expenses can include labor, permits, materials, and additional equipment such as the automatic transfer switch.

Operating Costs: Consider the ongoing costs of fuel and maintenance. Natural gas and propane are typically less expensive than diesel. Regular maintenance, including oil changes and part replacements, will also add to the operating costs.

Financing Options: Some manufacturers and dealers offer financing options, allowing you to spread out the cost over time. This can make purchasing a standby generator more affordable.

Long-Term Savings: While the initial investment may be high, a standby generator can prevent costly damage to your home during power outages and provide peace of mind. Evaluate the long-term benefits and savings when considering the cost.

9. Additional Features

Modern standby generators come with various features that enhance convenience and performance.
