A standby generator provides backup power during outages. It can keep essential systems running and offer peace of mind.

Understanding Power Outages

Power outages can happen for many reasons. Severe weather, equipment failures, and accidents are common causes. Some outages last minutes, while others can go on for days.

Frequent or long outages can be very disruptive. They may spoil food, stop heating and cooling systems, and cut off communication. For businesses, outages can lead to lost income and productivity.

It’s helpful to track how often outages occur in your area. Keep a log of when they happen and how long they last. This information can guide your decision about getting a generator.

Benefits of a Standby Generator

A standby generator kicks in automatically when the power goes out. It can power your whole house or just key items. This backup power keeps life running smoothly during outages.

With a generator, you can keep your fridge cold and your lights on. Your heating or air conditioning will work too. You’ll be able to charge phones and use computers.

For some, a generator is more than convenient – it’s vital. People who work from home need power to do their jobs. Those with medical devices rely on electricity for health reasons.

Generators also protect against water damage from frozen pipes in winter. They can help prevent mould growth in basements after heavy rains and power loss.

Selecting the Right Generator

Choosing an appropriate generator for roof installation requires careful consideration of fuel types and power output. The right generator will provide reliable backup power while meeting local regulations and your home’s energy needs.

Generator Types and Fuel Sources

Roof-mounted generators come in various fuel options. Natural gas generators connect to existing gas lines, offering continuous operation. Propane generators use tanks that need refilling but burn cleaner than other fuels. Diesel generators are durable and efficient but may have storage limits. Gasoline models are common but require frequent refuelling.

LP gas (liquid propane) generators are another option, using the same fuel as many home appliances. Each fuel type has pros and cons in terms of cost, availability, and runtime. Consider your area’s fuel accessibility and storage regulations when deciding.

Determining Appropriate Size and Watts

Calculating the right generator size is crucial. Whole-home generators typically range from 7,500 to 38,000 watts. List all appliances and devices you need to power during an outage. Add up their wattage requirements, including starting watts for motors.

A professional can help determine the correct size. Undersized generators won’t meet your needs, while oversized ones waste fuel and money. Home standby generators often come in set sizes, so you may need to round up to the next available option.

Consider future needs and any planned additions to your home. It’s better to have slightly more capacity than not enough. Remember, roof installations may have weight limits, affecting your size options.

Legal and Safety Considerations
