An unexpected brownout can be a real nuisance, with lights flickering, appliances on the fritz, and intermittent power. During these times, many homeowners ask themselves if they can keep some essential equipment on and at least enjoy a degree of comfort by buying a generator. This blog post will examine brownouts and whether you can use a generator in one. In addition, it will weigh the pros and cons of doing so and offer helpful hints on safely carrying out generator usage in these circumstances. Prepared for some power fluctuations? Or maybe just wondering about generator usage? This guide will surely give you some good insight.
Understanding Brownouts and Power Outages
Slight variations in affluence and power outages interrupt the electrical supply, but the causes and effects vary. A brownout indicates a voltage drop, thus dimming lights and reducing the electrical power with which devices function. These are often intentional, imposed by energy providers to avoid overloading the grid. On the other hand, a power outage is a full loss of electricity in the delivery system due to equipment failures, storms, or accidents. While both bear upon normal day-to-day activities, a brownout will allow a few devices to work. In contrast, an outage would usually call for the installation of a secondary source of energy.
What is a Brownout?
In technical terms, any slight drop in voltage lasting for a short duration (~60 seconds) is considered a brownout. Brownouts may be caused anytime utility providers implement a voltage reduction strategy to curtail demand during peak hours or a grid supply problem. During a brownout, one may observe lights dimming; while appliances may have difficulty operating at this low voltage, most continue working at reduced efficiency.
Differences Between Brownouts and Blackouts
Scheduling blackouts can be used for power conservation, load balancing, or system maintenance. Electric loads are rarely disconnected entirely during a brownout; their voltage is reduced partially. Devices, depending on their design and the voltage reduction, may continue working but in a less efficient manner or even completely fail. For instance, an air conditioner requiring the whole power range might shut down during the brownout period. Planned brownouts are sometimes used, allowing the power companies to give prior notice to consumers; unforeseen brownouts can take shape too, where rapid imbalances occur in the grid.
In comparison, a blackout is a total power outage. Causes of blackouts include bad weather, system failures, natural disasters, or anything that prevents the grid from operating. Unlike brownouts, blackouts usually happen without warning, leaving regional areas without power for extended periods. The U.S. Energy Information Administration (EIA) reports that, in 2022, an average electricity customer in the United States experienced 1.2 outages with a total lasting period of about seven hours.
Technically speaking, a voltage reduction during a brownout does not totally stop the flow of electricity, thereby preventing long-term burns or damage to equipment. In short, in a blackout, the complete absence of electricity causes serious disruption unless an alternate source of power or generators is provided to continue operations.
Therefore, it becomes imperative to ontogenize these differences in preparing for either situation. Both affect homes and companies alike; nevertheless, the concomitant use of surge protectors during brownouts and battery back-ups at blackouts will limit damages and guarantee safety.

Generator Options for Power Outages
Generators are a good temporary power solution during power outages, allowing you to keep running a few essential appliances and/or systems. Two options are always considered: portable and standby generators.
- Portable Generators: They are cheap, easy to get around, and made to provide a temporary power service. Gasoline or propane is supplied to these generators, making them a flexible option for short-term outages. They must be operated manually and adequately ventilated because of carbon monoxide gas formation.
- Standby Generators: These are permanent installations connected directly to the home or business. Upon an outage, it will go through a cut, powering the entire property. It is more costly than the former, yet it provides a more seamless and potent backup that often uses local fuels, such as natural gas or propane.
When choosing a generator, consider your power demand, your budget, and the length of time you are likely to be without power in your area.

Choosing the Right Generator for Your Needs
Choosing the best generator is a worthy consideration of one’s individual needs; for example, it depends on power requirements, budget, fuel choice, and the particular time frame for power outages to assess several options. Here are five primary considerations to help you with your choice:
- Power Output
- Find out the amount of watts your devices and appliances need during an outage.
- Portable generators usually range from 3,000 to 8,000 watts, suitable for powering essentials like fridges, lights, and small electronics.
- Standby generators can provide from 10,000 up to 50,000 watts: enough to power an entire home or a business.
- Fuel Type
- Gasoline: It is readily available but may not last long in storage. Most portable generators run on gasoline.
- Propane: Burns cleaner and can power both portable and standby generators. It requires storage tanks.
- Natural Gas: Provided continually by the utility lines but limited to areas with natural gas infrastructure. The ideal choice for standby generators.
- Diesel: Efficient in fuel consumption and runs long hours. It is generally used for bigger standby units.
- Run Time and Fuel Efficiency
- Try to find models balancing fuel consumption and runtime that meet your needs.
- Portable generators usually provide 6-12 hours of continuous operation on a full tank of fuel, yet standby generators offer indefinite operation with an attached supply.
- Mobility and Installation
- Well, a portable generator is lightweight and compact in design, but manual setup and connection are required for frequent movement.
- Standby generators are permanently installed, fully automated, and integrated into your property’s electrical system, freeing you from manual operations during an outage.
- Cost and Maintenance
- Portable generators are more cost-effective, ranging from $300 to $2,500, depending on size and features.
- Standby generators, however, have an initial cost between $2,000 and $10,000, including installation; thus, less manual intervention is required, and standby generators offer utmost reliability.
- Scheduled maintenance, such as oil changes and a system check, is equally required for both.
Considering and matching these factors with your requirements would better equip you with the know-how to choose a generator that will provide safety, convenience, and reliability when required during outages.
Appliances You Can Power with a Generator
Generators come to help in outages. They provide electricity for essential appliances. What can be powered depends on the generator’s wattage and capacity. Below is a detailed list of common appliances and power consumption to help correctly select a generator for your needs:
- Refrigerator and Freezer: A regular fridge consumes 600 to 800 watts, and a freezer slightly more, ranging from 500 to 600 watts. So, to preserve food and perishables, a generator giving out 1,500 running watts should suffice.
- Lights: LED light bulbs generally use 10 to 20 watts; therefore, you can power quite a few lights with a very low wattage requirement.
- Heating Systems or Space Heaters: A 1,500-watt space heater is pretty standard; maybe your heating system requires more, so look at its requirements.
- Air Conditioners: Window ACs range from 1,000 watts for small ones to 2,500 watts for bigger models, with the central air system demanding more, maybe up to 5,000 watts or so.
- Television and Media Devices: TVs can consume anywhere from 100 to 400 watts, and when devices such as cable boxes or gaming consoles are added, the power all adds up to 500 watts needed for entertainment consumption.
- Kitchen Appliances:
- Microwave Oven: A Small microwave uses 600-1,200 watts.
- Blender or Mixer: Depending on usage, these require 300-700 watts.
- Coffee Maker: The drip coffee maker uses 800-1,200 watts.
- Electronic Devices: Laptops consume 50-75 watts, and smartphone charging needs less than 10 watts. It’s easier to charge these with a generator that has USB and regular ports.
- Pumps and Motors:
- Sump Pump: The average sump pump uses 800-1,200 watts of power, but startup watts may be much higher.
- Well Pump: Depending on size and capacity, it may require about 1,000-2,000 watts.
Selecting the Right Generator
To calculate the wattage required, calculate the total running wattages for all the appliances you intend to use simultaneously, and add starting watts for appliances with motors. Portable generators generally rate 3,000 to 7,000 watts and are considered basic home use; gas-powered generators provide higher than 10,000 watts to accommodate more appliances and systems running simultaneously.
Knowing what the appliance requires for power ensures electric outages do not interrupt the power supply, thus maintaining comfort and working families. Always check for the manufacturer’s details specific to the wattage requirements.
Safety Guidelines for Using a Generator During Brownouts

Common Safety Risks and Precautions
While using a generator, understanding the most common safety hazards and taking appropriate precautions to avoid incidents can keep the operation safe. Here are five main dangers and the precautions needed to address them effectively:
- Carbon Monoxide Poisoning
- Hazard: Generators emit carbon monoxide, a colorless, odorless, and fatal gas. The concentration of CO can increase when used in an enclosed space or near an open window.
- Precaution: Run your generator out in the fresh air, far off windows, doors, and vents. Make sure you install a battery-operated carbon monoxide detector to monitor carbon monoxide levels continuously. According to the Centers for Disease Control and Prevention (CDC), more than 400 deaths and thousands of injuries due to CO poisoning occur annually in the US, many from improper generator use.
- Electric Hazards
- Hazard: Improper shelling or overloading the generator’s capacity can cause electric shocks or fires.
- Precaution: The generator should be adequately grounded and never be used with wet hands. Use an extension cord of heavy-duty rating, especially for outdoor use, and never overload a generator beyond its rated capacity. The Consumer Product Safety Commission (CPSC) recommends calculating the wattage your appliance would require beforehand to avoid overload.
- Fuel-Related Fires
- Hazard: Fuel spills while refueling a hot generator may cause a fire.
- Precaution: Let the generator cool down before refueling. Store fuel in approved, non-flame-proof containers away from the generator and any ignition source. Studies show that improper fuel handling accounts for many generator-related fires.
- Overheating
- Hazard: The generator may overheat whenever it has been running for a prolonged time or has poor ventilation, thus damaging the equipment or creating a fire hazard.
- Precaution: Keep the generator in an area with sufficient ventilation and ensure that nothing is blocking the vents. Follow the manufacturer’s instructions regarding how long to operate the generator and when to perform maintenance activities.
- Noise Pollution
- Hazard: The generators are loud enough to cause hearing damage or disturbance to neighbors.
- Precaution: Set up sound-dampening covers or barriers to mitigate noise, and comply with local noise ordinances. Also, think about purchasing a quieter inverter generator if the need to run the generator is frequent or if it is being used at night. OSHA has recommended that extended exposure to noise above 85 decibels could cause hearing loss, hence the need for using protection.
By recognizing these hazards and employing the mentioned precautions, generator users can minimize safety concerns while effectively generating power during brownouts or emergencies.
Proper Setup and Ventilation
Generator setup and ventilation are vital considerations that I look into, so placing the unit outdoors in a dry and well-ventilated area is essential. It must be kept away from any windows, doors, or vents due to the danger of carbon monoxide accumulation. Following the manufacturer’s instructions for site selection, it should be at least twenty feet from any living space. On top of that, if you have a carbon monoxide detector around, it doesn’t hurt- the extra layer of safety is well worth it. When taking such precautions, I can safely use the generator without putting my family or anyone else at risk.
Best Practices for Generator Operation
Uninterrupted and safe generator operation can only be guaranteed if maintenance is on time. The oil should be checked and changed as recommended; remember to clean the air filter and check spark plugs, which should be on your routine list. Keep your fuel in storage containers approved for this usage and stabilize it to prevent deterioration. Before maintenance begins, ensure the generator is completely switched off and cooled down from operation. Keeping the generator clean and well-maintained will lengthen its lifespan and improve its performance.
Connecting a Generator to Your Home
I use a transfer switch that meets local electrical codes for the safe and proper connection of a generator to the home. I then call a licensed electrician to install the switch that will prevent backfeeding from the house to the utility lines for the safety of the utility workers. Then I connect the generator to the transfer switch via a heavy-duty extension cord or plug wire rated for the power output of the generator. Before turning on the generator, the main power switch for the home will have to be switched off. Then, with the generator running, I energize only those necessary circuits, not to overload the system.
Maintenance Tips for Efficient Performance
Proper maintenance is essential to ensure efficient generator operation anda reliable supply when needed. Below is a detailed discussion about each maintenance requirement.
- Oil Change
Check your generator’s manual for oil change intervals, usually after 50 to 100 hours. The use of premium synthetic oil can improve your engine’s performance and durability. After a Google search, I found it was stated that synthetic type oils like 5W-30 would be best for most modern generators, especially in cooler temperatures.
- Check and Change Air Filters
A dirty air filter will choke your generator and reduce efficiency. Check the air filter every 25 hours and replace it when it appears clogged or worn. Clean air filters raise power output because they allow for proper airflow through the engine.
- Test for Sparkplugs
They should be checked every 100 hours of operation. If the spark plug is corroded or fouled, it must be cleaned or replaced to aid smooth starting and uniform power generation.
- Run Monthly
Run your generator for about 20 minutes once a month to prevent fuel line clogging and keep all internal parts lubricated. This procedure of running the generator under load is called exercising the generator and also helps identify any potential problems beforehand.
- Use Fresh Fuel and Stabilizer
Old or stale fuel is a major cause of starting problems and engine damage. It is advised to replace unused fuel every six months and consider a fuel stabilizer to extend the life of the fuel. Online sources suggest that generator fuel should be sulfur-free or ethanol-free gasoline to reduce carburetor blockages.
- Check and Clean Battery
Check and keep the battery fully charged and free of corrosion if your generator is a standby generator or has the electric start feature. Poor battery connectivity will cause starting failures in the event of an emergency.
- Know Load Capacity
You do not want to overload your generator; try to estimate the total wattage of the connected appliances. Working with at least 80% of the generator capacity prevents overheating and keeps mechanical parts working long.
- Professional Servicing
Though you can do your basic maintenance, professional servicing should be done at least once a year. The experts will run more complex diagnostics, check voltage regulators, and inspect wiring.
- Proper Storage When Not in Use
If you plan to store it for quite some time, drain the fuel system, disconnect the battery, and cover it with a protective sheet against dust and moisture. For better maintenance, keep it in a cool and dry environment.
By following these maintenance tips, the generator’s working life can be maximized, maintenance costs lowered, and top performance is ready to deliver when the demand is high. Besides helping with generator maintenance, it can also help minimize the risks of power disruptions, thus keeping the generator up and giving you full peace of mind.
Monitoring Fuel Levels and Usage
Fuel level monitoring and usage should be done appropriately for your generator to work efficiently. Periodic checks and precise tracking can help prevent unexpected shutdowns, wastage of fuel, and ensure that it runs at optimum capacity during critical times. Below are five means of monitoring fuel levels effectively:
- Install Fuel Level Sensors
Modern fuel sensors provide real-time data on fuel levels and warn you when the tank requires refilling before it is too late.
- Use a Generator Management System (GMS)
The GMS integrates with your generator to track fuel consumption and generate usage reports, ensuring accurate data management.
- Keep a Fuel Log
This can be manual or digital, logging all details of fuel additions, consumption rates, and refills to detect patterns or irregularities.
- Conduct Regular Inspections
Check all fuel tanks physically and verify the sensor readings, and search for signs of any leakages or contamination.
- Set Alerts for Low Fuel Levels
Configure your monitoring system to provide low fuel alerts and notifications when fuel reaches a critical level to prevent interruptions in operations.
These will help the user optimize fuel use, properly schedule refueling, and avoid unnecessary downtime. Combined, such tracking and monitoring help keep your generator’s reliability intact while saving on operating costs.
Common Misconceptions About Generators
Generators are essential tools during outages, yet off-grid locations, construction sites, and occasions heavily depend on this power source. This flexibility, in essence, proves an advantage to the generator when it is used for purposes other than emergencies.
- A Larger Generator Is Always Better
Generator size should simply be according to personal power needs. An oversized generator could consume more fuel needlessly and give you more hours of maintenance than required. Conversely, with smaller generators, there’s a risk that it cannot handle the power load adequately.
- Generators Run Well Without Regular Maintenance
They must be afforded some maintenance work to ensure reliability and the efficient operation of generators. If no maintenance is applied, there will be breakages over time, reduced working life, and an increase in long-term costs.
- Generators Are Noisy and Disruptive
New generation generators come with a set of noise-reduction features that make them practically quiet compared to the old generation ones. Also, keeping them serviced and well-maintained ensures the continuous quiet operation of the unit.
All in all, these misconceptions should be considered so that a good choice can be made when buying, using, or maintaining a generator.
Can You Use a Generator Indoors?
Operating a generator indoors can be fatal, as it emits carbon monoxide, which is colorless and odorless, and can kill an individual. Therefore, it must be used only in a well-ventilated place outdoors. Also, keep it away from any openings such as windows and doors.
