You already know the benefits of a standby generator (also known as a whole house generator) and why they are superior to portable generators:
- They turn on automatically in the event of a power failure whether you are home or away.
- They provide full protection, preventing everything from spoiled food to bursting water pipes to lost documents.
- They let you live, work and relax comfortably in your home until the power comes back on.
So, what are the important things to consider in buying a standby generator?
How Much Power Do You Need?
That depends on what you want to continue to run. It could be the most vital things like your refrigerator, sump pump, and HVAC system. Or it could be (and we would recommend) everything.
Here are the wattage requirements for many appliances you might want to protect:
| Appliance | Wattage Requirement |
| Air Conditioner | 2,000-5,000 |
| Dryer | 1,800-6,000 |
| Microwave | 600-1,500 |
| Refrigerator | 300-800 |
| Space Heater | 700-1,500 |
| Sump Pump | 1,300-2,150 to start and 800-1,000 to operate |
| TV | 50-300 |
Power Source
There are three types of power sources. We will eliminate diesel powered sources, as they provide much more power than the typical home needs and are also much more expensive. The other two options both provide up to 26,000 watts, or 26 kilowatts (kW). As you can see from the table above, that is sufficient to power a typical home. The two options:
- Natural gas. This is the preferred option if you have a natural gas line. Once your generator is hooked up to that line, you will never run out of fuel.
- Propane. If you do not have a natural gas line, the alternative is propane. Propane comes in tanks that can run out, so you will always want a second tank for when the first one runs out. Going this route, make sure you purchase a generator with a fuel gauge that will tell you how much propane is left.
Transfer Switch
The transfer switch is what transfers power from the generator. While there are some transfer switches that must be turned on manually, you will want an automatic transfer switch. That way the generator will turn on automatically whenever the power goes out, so no worries if the power goes out while you are sleeping or away.
Enclosure
Since the standby generator sits outside and is exposed to the elements, you will need an enclosure. Aluminum or composite enclosures are best as they will prevent rust and corrosion.
Remote Monitoring
Many newer models are Wi-Fi enabled, so you (and/or your electrical contractor) can use your tablet or mobile phone to both control the generator and check diagnostics. The generator can also integrate with other Wi-Fi devices in your home.
Standby Generator Maintenance
Make sure the company that sold you the generator offers a maintenance plan including a service schedule and remote monitoring. Maintenance can extend the life of the generator, and a maintenance plan may be required to keep the warranty valid.
