Understanding your needs for backup power

If you’re interested in backup power, such as a permanently installed or portable backup generator for your home, Reliant is here to help.

A first step is to evaluate your home's energy requirements, and what will give you comfort, connectivity and peace of mind during an outage.

Begin with a list of the appliances and systems you want to keep powered during an outage. That probably includes essential lighting, refrigeration, heating or cooling systems, communication devices and vital medical equipment.

When you know the start-up and running  wattage needs of these essentials, you'll have a good starting point for your generator’s needed capacity. Of course, you can always begin the process by consulting with a professional.

Types of generators

Next, you can get a handle on the basic types of home generators. Whether you value flexibility, reliability or efficiency (or all of these qualities and more), there's a generator that fits your lifestyle. Think of generators mainly in terms of their fuel type and whether they are permanently installed or portable.

Permanently installed vs. portable generators

There are two primary types of backup generators: permanently installed (also called "standby" and "whole-home") and portable.

Permanently installed generators are installed outside your home and are designed to automatically activate when the power goes out, delivering continuous power.

Portable generators, on the other hand, are mobile units that require manual setup and fueling. They offer versatility, but the trade-off is you may need to be hands-on when the time comes to use them.

Generator sizing

What capacity of generator do you need for your home?

As mentioned above, a good starting point is having a look at the wattage requirments of the devices you want to power together during an outage. But this is truly a starting point.

In terms of permanently installed options, Reliant offers you access to Generac® Generators. As one of the leading manufacturers of home backup generators in the U.S., Generac offers a wide range of residential and commercial choices.

In terms of sizing, here are some guidelines from Generac.

• 14kW generator system for a 1,000 - 2,000 sq ft home
• 18kW generator system for a 2,000 - 3,000 sq ft home
• 24kW generator system for a 3,000 - 4,000 sq ft home

Fuel types: pros and considerations

Generators also vary in terms of their energy source. These include natural gas, propane and diesel. Stored battery power can also serve a critical role in backup systems.

Each fuel type has its advantages in terms of availability, convenience and environmental impact.

Solar panels have also emerged as an alternative, harnessing sunlight to generate electricity and offering a renewable, eco-friendly solution for generating and storing backup power.

When paired with backup-battery storage, residential rooftop solar can provide a clean, renewable whole-home energy solution ideal for both everyday power and backup when needed.

Let's dive into the pros and cons of the most common fuel types for backup generators, helping you make an informed decision that simplifies your life.

Gasoline

• Pros: accessibility and portability ─ Gasoline is widely available, making it a convenient option for many homeowners. Ideal for portable generators, gasoline allows for easy refueling and transport.
  
  
• Considerations: shelf life and volatility ─ Gasoline has a limited shelf life, even with stabilizers, and requires proper storage. It's highly flammable, posing safety risks if not handled correctly.

Natural gas

• Pros: convenient and clean burning ─ With a direct line to your home, natural gas offers an uninterrupted fuel supply. It's cleaner than other fossil fuels, producing fewer emissions.
  
  
• Considerations: installation cost and infrastructure ─ Initial setup will require professional installation and can be costly. In the event of a natural disaster, the supply line could be compromised.

Propane

• Pros: long shelf life and energy efficiency ─ Propane can be stored for very long durations, making it reliable for emergency use. It burns cleaner and more efficiently than gasoline or diesel.
  
  
• Considerations: storage space and cost ─ Requires space for a propane tank, which may not be feasible for all properties. Depending on market prices, propane can be more expensive than other fuels.

Diesel

• Pros: energy density and durability ─ Diesel engines are known for their efficiency and long run times. Diesel generators tend to have a longer lifespan and are more robust.
  
  
• Considerations: noise, emissions, fuel availability ─ Diesel engines are louder and produce more emissions than gas or propane. In emergencies, diesel fuel might be harder to obtain due to its use in commercial and emergency vehicles.

Solar power

• Pros: renewable, silent, battery backup ─ Solar systems harness the sun's energy, providing a clean, inexhaustible power source. They operate silently, making them ideal for residential use. Rooftop panels naturally pair with battery backup for a renewable, flexible whole-home solution
  
  
• Considerations: initial investment and weather dependence ─ The upfront cost of solar panels and backup storage batteries can be a significant impact on many household budgets. Efficiency can be impacted by weather conditions and may not be ideal in all geographic locations.

Generator safety first

Safety should always be a top priority when using backup generators. What should you consider?

• Carbon monoxide risks and detection — Generators can produce carbon monoxide (CO), a colorless, odorless gas that can be deadly. Generators should be used only with proper ventilation. Carbon monoxide detectors in your home, especially near sleeping areas, can provide early warning of CO buildup. When it comes to your generator itself, always consult with a qualified installer and follow manufacturer instructions.
  
  
• Safe installation practices and rules to observe — If you opt for a hands-on portable generator, always strictly follow setup and usage guidelines, which should be provided by your unit's manufacturer.

Permanently installed standby generators should be installed and maintained by a licensed professional to help ensure safety.

Installation considerations

Professional installation can help ensure your generator is safe and performing efficiently.

A professionally installed transfer switch for your whole-home generator allows for safe connection of the generator to your home's electrical system.

Manual transfer switches work when a person operates them, as opposed to automatic transfer switches, which seamlessly switch to generator power without user intervention.

Another decision to make when installing is whether you want a generator that runs on continuously supplied fuel, or on stored fuel.

In the first case, your generator would connect to a natural gas line; a generator using stored fuel would have a tank with propane or diesel. Each option has its advantages and considerations, depending on factors like fuel availability, cost and maintenance requirements.

Maintenance and care

Regular maintenance will help ensure your backup generator runs at its best — and that it’s ready to perform when needed. If you can stay on top of maintenance, you’ll likely increase the lifespan of your generator and ensure its reliability.

If you choose a permanently installed generator, chances are you'll also have a recurring service agreement with your installer.  Your generator should come with specific manufacturer guidelines. Common best practices touch on oil changes and filter replacements.

Here are regular maintenance tasks to consider

• Regular inspection and cleaning — Your generator should be free of any signs of wear, damage or leaks. Ensure the generator and its surroundings are clean and free from debris. 
  
  
• Professional annual checkup — Even with diligent personal maintenance, having a professional inspect your generator annually is a wise choice. They can perform more complex checks and maintenance tasks, ensuring your generator's longevity.
  
  
• Test runs — Run your generator periodically to ensure it's ready for action. This helps lubricate the engine and identify any issues before an emergency arises.

Choosing your backup power solution

Installing a backup generator can keep your life and home running as usual, even during a storm.

Choosing the generator that’s right for you involves considering what fuel you prefer it to run on, and whether you want a generator that is permanently installed or one that’s portable.

Reliant can help you select a backup power solution tailored to your home's requirements.*

It’s a good idea not to wait until the next outage strikes — instead, take action with time to be prepared.
