Backup Power: Protecting Your Home or Business During Outages

Backup power is more than just a convenience—it’s a lifeline. It keeps your family or employees safe, protects against significant financial losses, and ensures your business can remain operational during extended outages.

The Role of Automatic Standby Generators

Automatic standby generators are designed to take over seamlessly during a power outage. Here’s how they work:

  • Always On Standby: The generator monitors your utility power continuously.
  • Automatic Activation: When utility power is interrupted, the generator starts and switches your home or business to generator power without requiring any manual action.
  • Automatic Shutdown: Once utility power is restored, the generator shuts down and transitions back to the main power supply.

This hands-free operation ensures uninterrupted comfort and safety.

Gas vs. Diesel Generators:
Choosing the Right Option

One of the most common questions we receive is whether to choose a gas (natural gas or propane) or diesel generator. The answer depends on your specific needs, but here’s a comparison to guide your decision.

Key Factors to Consider

  1. Fuel Type
    • Gasoline is primarily used in portable generators and is excluded from this discussion.
    • Diesel and gas generators (natural gas or propane) are the primary options for long-term, permanent backup power.
  2. Longevity Both gas and diesel generators can last for many years with proper maintenance, but their lifespan depends on:
    • Component Quality: Higher-quality parts typically last longer.
    • Maintenance Practices: Regular servicing is essential for any generator.
    • Operating Conditions: Harsh environments may reduce lifespan.
    • Usage Patterns: Heavy or continuous use may require more frequent maintenance.

Diesel Generators

Advantages:

    • Durability: Diesel generators are built for demanding applications and continuous use, offering robust performance even under heavy loads.
    • Longer Lifespan: Typically, diesel engines last longer due to their construction and efficiency.
    • Efficiency: Diesel fuel has a higher energy density, meaning it generates more power per gallon.

Challenges:

    • Fuel Storage Issues: Diesel fuel can attract water and develop microbial contamination (commonly called the “diesel bug”), which can degrade fuel quality and lead to clogged filters or system blockages. Proper storage and fuel conditioning are essential.
    • Maintenance: Diesel systems require routine servicing to prevent microbial-induced corrosion (MIC) and other issues. Without treatment, stored diesel fuel may degrade within 6–12 months.

Natural Gas and Propane Generators

Advantages:

    • Cleaner Operation: Natural gas produces fewer byproducts, reducing engine wear and keeping components cleaner.
    • Consistent Fuel Supply: Natural gas is delivered through utility lines, eliminating the need for onsite storage.
    • Lower Temperatures: These engines operate at lower temperatures, potentially extending their lifespan.

Challenges:

    • Sensitivity: Natural gas generators can be more sensitive to operating conditions, requiring careful monitoring and maintenance.
    • Dependence on Utility Lines: In disasters that disrupt natural gas lines, the fuel supply may be interrupted.

Summary: Diesel or Gas?

Diesel generators generally offer a slightly longer lifespan due to their durability and efficiency, but natural gas generators can also last many years with proper care. Your choice will depend on factors like fuel availability, operating conditions, and specific power requirements.

Maximizing Generator Lifespan

To ensure the longevity of your generator:

    • Follow the manufacturer’s maintenance guidelines.
    • Schedule regular maintenance, including oil changes, filter replacements, and system inspections.
    • Implement a fuel conditioning program if using diesel to prevent contamination.
    • Partner with a trusted provider like Sirius Power for low-cost preventive maintenance plans.
