## Buying Guide: What to Consider When Choosing a Standby Generator with Transfer Switch

Choosing the right standby generator with transfer switch involves several important considerations. Here’s what you need to know to make an informed decision:

### Power Needs: How Much Power Do You Need?

The first step is to determine your power needs. This involves calculating the total wattage of the appliances and devices you want to power during an outage. Make a list of essential appliances, such as refrigerators, freezers, lights, heating/cooling systems, and medical equipment. Add up their wattage requirements to get an estimate of your total power needs. It’s always better to overestimate slightly to ensure you have enough power. Most standby generators are rated in kilowatts (kW). One kilowatt equals 1000 watts. A 20kW generator, for example, can supply 20,000 watts of power.

### Automatic vs. Manual Transfer Switch: Which is Right for You?

The transfer switch is a critical component that connects the generator to your home’s electrical system. It allows you to safely switch between utility power and generator power. There are two main types of transfer switches: automatic and manual.

* **Automatic Transfer Switch (ATS):** An ATS automatically detects a power outage and switches to generator power within seconds. This is the most convenient option, as it requires no manual intervention. ATS models are generally more expensive but offer the greatest peace of mind, especially if you’re not home during an outage.
* **Manual Transfer Switch (MTS):** An MTS requires you to manually switch between utility power and generator power. This involves flipping a switch on the transfer switch panel. MTS models are less expensive but require you to be present to operate them.

For most homeowners, an automatic transfer switch is the preferred option due to its convenience and ease of use.

### Fuel Type: Natural Gas vs. Propane

Standby generators typically run on either natural gas or propane. Both fuel types have their pros and cons:

* **Natural Gas:** Natural gas is typically cheaper than propane and is supplied directly to your home via a gas line. This eliminates the need for fuel storage. However, natural gas may not be available in all areas.
* **Propane:** Propane is readily available and can be stored in tanks on your property. This provides a reliable fuel source, even if natural gas service is interrupted. However, propane tanks need to be refilled periodically.

The best fuel type for you will depend on your local availability and personal preferences.

### Noise Level: How Quiet Do You Need Your Generator to Be?

Standby generators can produce a significant amount of noise during operation. If you live in a densely populated area or are sensitive to noise, consider a generator with a sound enclosure or other noise-reducing features. Some generators are designed to operate at significantly lower noise levels than others. Check the generator’s decibel (dB) rating to get an idea of its noise output.

### Installation and Maintenance: What’s Involved?

Standby generators require professional installation to ensure they are properly connected to your home’s electrical and fuel systems. The installation process typically involves pouring a concrete pad, connecting the generator to your home’s electrical panel and fuel supply, and testing the system. Regular maintenance is also essential to keep your generator running smoothly. This typically includes oil changes, filter replacements, and inspections. Be sure to factor in the cost of installation and maintenance when budgeting for a standby generator.

### Warranty and Support: What’s Covered?

A good warranty provides peace of mind and protects you from unexpected repair costs. Look for a generator with a comprehensive warranty that covers parts and labor. Also, consider the manufacturer’s reputation for customer support. Choose a brand that offers reliable technical assistance and readily available replacement parts.
