Types Of Standby Generators
Portablegenerators are easy to move and use in different places. They are usually smaller and less expensive. Permanentgenerators are fixed outside a building. They start automatically during power outages and provide more power.
Common fuel optionsinclude:
- Gasoline:Easy to find but needs frequent refills.
- Propane:Cleaner and can be stored longer.
- Natural Gas:Connected to home supply, no need to refill.
- Diesel:Powerful and good for long use.
An Automatic Transfer Switch (ATS)helps switch power from the main grid to the generator. It turns on the generator right after a power outage. This keeps your home powered without any delay or manual effort.

Power Requirements
Calculate your total power needsby adding the watts of all devices. Decide if you want to power only essential appliancesor your full home. Essential backup means just basics like lights, fridge, and heater. Full backup powers everything at once.
| Type | Definition | Example |
|---|---|---|
| Starting Watts | The extra power needed to start devices. | Air conditioners or refrigerators require more power to start. |
| Running Watts | The power needed to keep devices running. | Light bulbs and TVs use steady power after starting. |
- Make a list of all devices you want to power.
- Check each device’s starting and running watts.
- Add starting watts for devices that start at the same time.
- Choose a generator that covers the total starting and running watts.
Key Features To Consider
Noise levelsare important for comfort. Choose a generator that runs quietly. This keeps your home peaceful during power outages. Some models come with noise-reducing covers.
Run time and fuel efficiencyaffect how long the generator works. Longer run time means fewer refills. Fuel-efficient models save money and reduce trips to buy fuel. Check the fuel type: propane, natural gas, or diesel.

Preparing the site is key. Choose a flat, dry spot away from windows and doors. Clear any plants or debris to keep the area clean. The generator needs good airflow and no risk of flooding.
Professional installation ensures safety and proper function. Experts connect the generator to your home’s power system. They check fuel lines and electrical wiring for correct setup.
Local codes and permits must be followed. Contact your city or county office for rules. Permits may be needed before starting installation. This keeps the setup legal and safe.

Initial investmentincludes the price of the generator and installation. Bigger generators cost more but power more devices. Installation can vary depending on your home and local rules. Budget for this carefully.
Operating costscover fuel, maintenance, and repairs. Gasoline or propane prices can change, so expect varying fuel expenses. Regular oil changes and check-ups keep the generator running well. Plan ahead for these ongoing costs.
