Buying Guide – How to Choose the Best Natural Gas Standby Generators

Selecting the right generator requires careful evaluation of power needs fuel type safety and budget. Here are the critical factors to consider.

Power Output Requirements

Determine your wattage needs by listing essential appliances. Look for surge and running watts to ensure the generator can handle startup loads.

Choose a unit with enough capacity to avoid overloading during outages.

Fuel Type Compatibility

Tri fuel generators support gasoline propane and natural gas. Natural gas provides unlimited runtime via a home line making it ideal for long outages.

Confirm that your preferred fuel source is available before purchasing.

Safety Features

Safety features like CO sensors are vital for preventing carbon monoxide poisoning. These systems shut down the unit if dangerous gas levels are detected.

Prioritize models with built in carbon monoxide protection.

Runtime and Efficiency

Runtime indicates how long the unit runs on a full tank. Larger tanks extend runtime but increase weight and fuel requirements.

Opt for units that balance efficiency with portability needs.

Ease of Operation

Remote start or electric start options allow for convenient activation. Manual pull starts can be difficult in adverse conditions.

Look for control panels that simplify fuel switching and monitoring.

Transfer Switch Compatibility

A transfer switch integrates the generator with your home electrical panel. Ensure the unit is transfer switch ready for safe whole home backup.

Professional installation is recommended for all transfer switch setups.

Warranty and Support

Longer warranties indicate manufacturer confidence. Check coverage for engine and electrical components.

Access to customer support helps resolve issues quickly.

Budget Considerations

Prices vary based on features and power output. Higher cost units offer more safety and convenience features.

Weigh long term value against immediate upfront costs.

How to Use and Care for Your Natural Gas Standby Generator

Place the generator on a flat surface outdoors at least 20 feet from windows or vents to prevent carbon monoxide buildup inside the home.

Connect the generator to your natural gas supply using a quick connect adapter or a permanent line installed by a professional.

Regularly check oil levels and run the generator briefly every month to keep it in optimal working condition during emergencies.

Frequently Asked Questions

What is the difference between standby and portable generators?

Standby generators are permanently installed and auto start when power fails. Portable generators must be manually set up and connected to power loads.

Can I connect a generator directly to my home?

Never plug a generator into a wall outlet. Use a transfer switch installed by an electrician to prevent backfeeding and ensure safety.

How often should I test my generator?

Test your generator monthly for about 15 minutes. This ensures it starts properly and the oil is circulated before a real outage occurs.

Does natural gas cost more than propane?

Natural gas is usually cheaper per BTU than propane and is delivered via a pipeline. This makes it more convenient for long term outages.

What are transfer switches and why are they needed?

Transfer switches safely disconnect your home from the grid and connect it to the generator. They prevent dangerous backfeeding to utility lines.

Can I run sensitive electronics on a standard generator?

Standard generators have higher total harmonic distortion. Use inverter generators or units with low THD to protect computers and TVs.
