1. Portable Generators

Portable generators are ideal for occasional or short-term use during outages. Most models weigh between 60 and 250 pounds, making them easy to move and store but unsuitable for continuous operation over extended periods.

Typically run on gasoline, portable generators provide enough energy to power select appliances through standard two-prong outlets. Still, they can’t be connected to a home’s electrical panel without the installation of a transfer switch by a licensed electrician.

2. Standby Generators

Home standby generators are permanently installed near the home to provide backup power when utility power is disrupted automatically. Installed professionally, these units run on natural gas or liquid propane for continuous operation without refueling.

A standby generator’s automatic transfer switch seamlessly transitions the home’s power source to keep essential appliances like air conditioners, refrigerators, and sump pumps operating without interruption.

3. Inverter Generators

Large inverter generators produce steady power for sensitive electronics while being more fuel-efficient and quieter than standard portable models.

Though not as lightweight, inverter generators can run hardwired equipment like suitable pumps when connected to a home’s electrical panel. Their built-in inverters regulate electricity flow for smoother power quality suitable for cooling equipment and other appliances.

Calculating Your Power Needs

Understanding your home’s power needs is crucial when determining the right size generator. A few key factors must be considered to estimate the electricity flowing into your home accurately.

Factors to Consider

The frequency and duration of power outages in your area will affect generator selection. Frequent or prolonged blackouts mean a standby generator may be best for continuous power. You’ll also need to account for essential appliances, cooling equipment, and whether to run hardwired equipment like well pumps or sump pumps during outages.

Estimating Appliance Wattage

Use the continuous watts rating listed on appliances or look them up online to get a baseline power consumption figure. Remember, some items have surge watts needs when turning on. For example, air conditioners pull more electricity starting up versus steady operation. Be sure to account for these peak wattage requirements.

Accounting for Surge Watts

When totaling wattage needs, multiply an appliance’s running watts by three to estimate starting or surge watts. This ensures the generator you choose can reliably power electronic surges that occur briefly at appliance startup. Failing to consider surge loads risks overloading smaller generators that can’t sustain high temporary power draws.

In conclusion, carefully researching your home’s typical power requirements and factoring in surge loads will allow you to determine the correct size generator. Consider all essential appliances, cooling equipment needs, and whether you require power for hardwired items during outages. With accurate wattage estimates, you can select the best portable inverter or standby generator type and model.

Choosing the Right Size Generator

When choosing a generator for your home, there are a few key factors to consider to select the correct size generator that meets your needs. Understanding these factors, such as generator power output, fuel type and runtime, and automatic transfer switches, will help you pick a model that provides continuous electricity flowing to your home and cooling equipment during power outages.

Let’s examine some primary considerations when determining the size generator required. The generator power output, measured in watts, must match or exceed the total power consumption of all essential appliances, electronics, and systems you want the generator to run during an outage.

An easy first step is making a list of items like your refrigerator, window air conditioner, and well pump and noting each item’s continuous, surge, and running watts. Totaling these wattage requirements will give you a baseline for the minimum power output needed.

Generator Power Output

Portable generators typically run on gasoline and have output ranges from a few thousand watts for smaller mobile units to 8,000 watts or more for larger portable and inverter models. In contrast, home standby generators can be permanently installed and are optimized for continuous duty during extended outages.

Relying on natural gas or liquid propane for fuel, home standby generators have higher endless output capabilities from 10,000 to 40,000 watts or more, allowing them to power an entire home simultaneously reliably.

Fuel Type and Runtime

Portable generators have limited run times of 6-16 hours on a single gasoline tank, whereas home standby generators can operate indefinitely on a permanent fuel source. This makes standby models a much better choice for locations that commonly experience frequent or prolonged power outages.

Automatic Transfer Switches

Only home standby generators can be safely connected to a home’s electrical panel using an automatic transfer switch, which allows the generator to detect an outage and automatically supply electricity to crucial home circuits without needing to switch over or plug in appliances manually. This provides seamless, continuous backup power.

By analyzing these key factors, homeowners can determine the type and size of generator best suited to meet their needs during weather-related or unplanned power interruptions reliably. The right generator selection leads to long-term peace of mind.

Additional Considerations

When choosing a generator for your home, there are a few additional factors to consider beyond simply determining the necessary output for your power needs. Selecting the right type of generator involves weighing considerations like durability, noise levels, and installation requirements to find the best overall fit for your situation.

Durability and Weather Resistance

Portable generators are a convenient option but may not withstand extreme weather like heavy rain, snow, or high winds that could damage the unit or cause safety issues.

However, home standby generators are constructed with weather-resistant materials and automatic shutoff sensors to ensure continuous electricity flows to your home’s essential appliances, even during severe storms or natural disasters when your area is prone to power outages.

These permanently installed units are rated for all climate conditions, so you can feel confident relying on backup power regardless of weather.

Noise Levels

While portable generators typically run louder than other options due to their open design, inverter generators produce significantly less noise, around 60-70 decibels, comparable to normal conversation.

This makes them a better choice if you need to run a generator for an extended period or are concerned about disturbing neighbors. Home standby models are also very quiet, around 55-65 decibels, allowing sensitive electronics and cooling equipment to run without interruption from intrusive sound.

Installation and Maintenance

A licensed electrician must permanently install a home standby generator, route fuel lines, and set up the automatic transfer switch. However, this one-time setup ensures seamless, consistent power whenever needed, with no additional manual hookups required during an outage.

Portable units may need to be refueled more often as well. Overall, professionally installed home generators require less ongoing maintenance while providing maximum reliability and safety.
