What Is A Standby Generator?

In a power outage, a standby generator provides backup power to your residence, commercial and industrial applications, and facilities. Generally stationary and requiring a concrete footing as a foundation, standby generators are typically installed outside of your facility.

Standby generators are a dependable option that, based on the types of fuel and generator setup, can offer electricity for days during extended power outages. In contrast to prime or continuous generators, standby generators are only utilized during power disruptions caused by inclement weather, natural or artificial disasters, or regular blackouts caused by an aging power grid.

Standby generators restore power in the event of a utility power interruption. The most common causes of disruptions are storms and equipment malfunctions, but other causes include traffic accidents, animal damage, and even deliberate sabotage.

What Are The Benefits of A Standby Generator?

As a backup power source, standby generators not only keep the lights on, but they can also maintain a secure working environment for you and your employees. In a power outage, the air conditioner or heater will continue to operate without interruption.

  • Backup Power Source

The air conditioner, fridge, sump pump, and more appliances can all run on backup power from a single standby generator. Whether going off the grid permanently or temporarily due to an emergency, you should be able to operate everything at total capacity if your property is adequately estimated and installed.

  • Increased Power Capacity

The standby generators can do this because they have greater power capacities than most other generators and can operate for an extended period without requiring maintenance.

  • Always Standby

To be prepared for power outages and other emergencies, you must stock up on fuel, which is frequently in limited supply. These are not issues with whole-house generators, which can utilize gasoline from a significantly larger tank.

  • Commercial Use

Servers, processing machinery, and security systems are just some of the automated computer systems and equipment you may keep online with the help of a commercial standby generator. Most importantly, having a backup generator to keep your business operations running reduces profit loss and maintains productivity.

What Are The Types of Standby Generators?

Regardless of the cause of the power outage, electricity is required to maintain essential electrical circuits operational. A standby generator ensures that the household or business has sufficient power.

The backup system promptly detects a power failure and waits a few seconds for the power to return. If not, the generator engine is started.

  • Diesel Generator: Attached to standby diesel generators are fuel containers that supply fuel to the generator's internal combustion engine, enabling electricity generation. Diesel generators have a smaller storage capacity and a higher acquisition cost than their natural gas counterparts.
  • Gas Generator: Generators powered by natural gas in your area can bypass the need for a fuel storage tank by hooking up directly to the gas mains. As long as the main gas utility line is functional, the generator can run eternally without refueling. Maintenance of natural gas generators is more frequent, and gas service is typically cut off during a storm, tornado, or earthquake to prevent accidental explosions.    
  • Solar Generator: Technically, a solar generator is a power generator that runs on solar energy. It refers to using solar panels and portable power stations to capture, store, and distribute solar energy. The solar panels convert sunlight to electricity, then are deposited in a power plant.

With the advancement of LiFePO4 battery technology, you can use more electricity. Jackery Solar Generator 2000 Plus capacities range from 2 kWh to 24 kWh, sufficient for residential and commercial use. Jackery Solar Generator powers your residence with clean, renewable, and limitless solar energy. It is straightforward to capture sunlight during the day, even on cloudy or rainy days, and store energy for night use.

How Does A Standby Generator Work?

The electrical panel of your facility is directly connected to external fuel source standby generators (natural gas or diesel). In the case of home generators, the fuel type and generator dimensions determine what can be powered and for how long.

Most commonly, standby generators are coupled with an automatic transfer switch, which activates the standby generator within seconds of a power outage.

After a power disruption, the ATS switch disconnects your facility from the utility's primary power grid. After the facility has been safely and entirely disconnected from the power grid, the switch activates the generator to supply electricity to the electrical panel.

However, maintaining diesel and natural gas generators as standby generators is time-consuming, and they are more susceptible to being impacted by extreme weather conditions or running out of fuel. Choosing a solar generator as your home's standby generator is the best method to power your home with renewable energy during power outages.

Jackery Solar Generators: The Best Home Standby Generators

Due to their increased capacity and advanced solar technology, Jackery Solar Generators are the finest rechargeable home generators. It takes only sixty seconds to set up a solar generator, which is sufficient for emergencies.

Using a solar generator to power a residence takes advantage of the limitless and renewable energy sources of solar systems. But the first step is determining how much solar energy your home requires.

How Much Solar Power Do You Need?

Its wattage consumption must be determined to calculate the solar energy required for a residence. Then, using the Watt-hour formula, calculate the magnitude of the solar system for your home:

Watt-hours = Watts x Hours = (Volts x Amps) x Hours

For example, if your 5-amp window AC requires 120V DC, it is 600W. 4.2kWh (600W x 7H) of solar energy will be needed if the window AC is used for 7 hours daily.

In addition, running and commencing wattage can be used to calculate how much solar power is needed. Add the most excellent starting watts to each appliance's operating watts to determine the total starting watts required.
