Frequently Asked Questions
What are the key benefits of owning a backup generator?
A backup generator provides an immediate source of power during blackouts or power outages, ensuring that essential appliances like refrigerators, heaters, and medical equipment keep running. It brings peace of mind knowing that you won't be left in the dark during critical situations.
How do I determine the right size for my backup generator?
The size of your backup generator should be based on your power needs. Make a list of the appliances and systems you need to keep running during a power outage, then add up their wattage. This total will give you an idea of the generator size you need.
What is the difference between a portable and a standby backup generator?
Portable backup generators are smaller, can be moved around, and are manually operated. Standby backup generators, on the other hand, are permanently installed, automatically start when power is lost, and can power more appliances for a longer duration.
Is it safe to run a backup generator indoors?
No, it's not safe to run a backup generator indoors due to the risk of carbon monoxide poisoning. Always place your backup generator outdoors, away from windows, doors, and vents.
What type of fuel is best for a backup generator?
The choice of fuel—whether gasoline, propane, diesel, or natural gas—depends on factors like local availability, storage safety, and cost. Gasoline is readily available, but has a short shelf life. Diesel engines are efficient but noisy. Propane has a long shelf life and is clean-burning. Natural gas generators are convenient as they can be hooked to your home's natural gas line.
