Quick Answer
Standby generators can provide effective power backup during extended outages, but their effectiveness depends on factors like fuel supply, generator size, and maintenance. Even well-maintained units may struggle to power entire houses for extended periods without frequent refueling or risk of overheating.
Capacity and Fuel Considerations
When selecting a standby generator, it’s essential to match the unit’s capacity to your household’s power needs. A general rule of thumb is to choose a generator with a capacity 1.5 to 2 times your total connected load. For example, if your house requires 25 kilowatts (kW) of power during a typical day, look for a generator with a minimum capacity of 37.5 to 50 kW. Additionally, consider the fuel type and storage requirements. Propane or natural gas generators can be more convenient than diesel units, but they may require more complex installation and maintenance.
Installation and Maintenance Best Practices
Proper installation and regular maintenance are crucial to ensure a standby generator operates efficiently and safely during extended power outages. This includes installing the generator and its associated components (such as the transfer switch and fuel tank) according to the manufacturer’s instructions and relevant local codes. Regular maintenance tasks, such as oil changes, filter replacements, and spark plug cleaning, should be performed every 100 to 200 hours of operation, or as recommended by the manufacturer.
