How much does a home backup generator cost?

The cost of a home backup generator can vary depending on several factors, including size and capacity. A smaller generator meant to power a few essential appliances during an outage can cost anywhere from $3000 to $6,000. A larger generator that can power an entire household will range in price from $10,000. Also, consider the installation costs, as a licensed electrician may need to be hired for proper installation.

Maintenance costs should also be considered, as annual maintenance checks are necessary to ensure the longevity and effectiveness of the generator. While the initial cost may seem high, owning a backup generator can provide peace of mind during power outages and protect against expensive damages caused by blackouts.

Factors that influence the backup generator cost


The application or intended use of the generator plays a critical role in determining its cost. The primary reason is that different applications require varying amounts of power, directly impacting the generator's size and capacity.

Smaller generators that power basic appliances such as refrigerators are typically less expensive than larger models capable of powering an entire home. Investing in a more powerful generator that can handle all your home's needs may save you money in the long term by avoiding costly repairs from overloading a smaller system.


Factors such as local building codes, zoning laws, and permit requirements vary from region to region and impact the installation costs for the generator. The climate conditions in the area can also affect the generator's cost. For instance, areas prone to severe weather conditions may require more robust generators with bigger engines, resulting in higher prices.

The availability of fuel sources like propane or natural gas should be considered since it impacts the operating cost and price of the generator. Consult with professionals who have experience working within your area for accurate pricing and installation costs based on your specific needs.

Power Source

Various sources, including natural gas, propane, diesel, and gasoline, can power backup generators. The type of power source used will determine the overall cost of acquiring and installing the generator. Natural gas and propane are cleaner-burning fuels than diesel or gasoline. They are often preferred by homeowners who prioritize eco-friendliness and convenience.

However, these options have a higher initial installation cost since they require specialized equipment and licensing to install properly. Meanwhile, diesel or gasoline-powered generators may have lower upfront costs but require additional maintenance to ensure safe operation. Choosing the right power source will depend on various factors such as budget, location, and energy needs during a blackout scenario.

Generator Size and Output Capacity

A larger generator typically means a more significant power output capacity, translating into a higher price tag. However, other factors will determine the final cost, like the brand, fuel type, noise reduction, and portability. It's essential to consider your household power needs when selecting an appropriate generator size to avoid over or under-sizing. An undersized generator will provide an inadequate power supply, while an oversized one may unnecessarily drain your budget.

Generators Types

Portable generators are typically the least expensive option. However, these generators require manual setup and usage, which can be inconvenient during an emergency. Standby generators are installed permanently and automatically turn on during a power outage. They are more costly than portable generators.

Inverter generators provide clean energy that won't damage sensitive electronics and produce less noise than traditional mobile models. However, they tend to be more expensive than standard portable options due to their advanced technology.

How can you reduce the cost of the backup generator?

Use a sustainable power supply

Sustainable power sources, such as solar panels and wind turbines, generate electricity without relying on fossil fuels which can be expensive and damaging to the environment. These systems allow homeowners to harness renewable energy and reduce reliance on traditional energy providers.

Since the generator doesn't need to be used as frequently, it will have a longer lifespan and require fewer repairs. Sustainable power supply promotes environmental responsibility by reducing carbon footprint and contributing to global efforts towards sustainability.

Maintain or clean the backup generator yourself

Maintaining or cleaning the backup generator can significantly reduce the cost of operating a home backup generator. Regular maintenance ensures that the generator runs at optimal efficiency and minimizes wear and tear on its components. Care also extends the generator's lifespan and reduces costly repairs or replacements.

Performing routine checks on fuel levels and battery terminals ensures the generator is always ready to go when needed. Cleaning the unit also prevents debris buildup, which can obstruct airflow and cause overheating - leading to damage and higher electricity bills.

Purchase generators during off-seasons

During these times, demand for generators generally decreases due to inclement weather conditions being less prevalent. As a result, suppliers and manufacturers are typically looking to clear their inventory before such products become obsolete.

Thus, consumers can take advantage of lower prices and negotiate better deals due to excess stock, saving them more money. Purchasing during off-seasons also allows homeowners ample time for product research and comparison.

Rebates and incentives

These discounts are often part of larger energy conservation or sustainability initiatives encouraging people to adopt environmentally friendly habits and technologies. Manufacturers may offer product rebates to incentivize customers to purchase them, while governments may provide tax credits for installations that meet certain energy efficiency standards.

For example, in the United States, homeowners installing energy-efficient generators can receive upto $1200 annual tax credit. Consequently, more households can access reliable power sources during emergencies such as power outages caused by natural disasters.

Refurbished Generators

Refurbished generators reduces the cost of home backup generators by offering clients the opportunity to purchase certified pre-owned generators at a fraction of the cost of a brand-new unit. By refurbishing previously-owned equipment, the company can extend the lifespan of these generators and ensure their reliability for years to come.

Additionally, refurbished generators offers comprehensive testing and diagnostic evaluations on all refurbished units, ensuring that each generator meets or exceeds industry standards for performance and safety. Through this process, the company can reduce overhead costs associated with manufacturing new units while also passing along significant savings to customers.

Recommended generator for home backup

Zendure portable solar generators with battery storage are highly recommended for those needing reliable and efficient power. These generators have a high-capacity lithium-ion battery that can store large amounts of energy. The solar generators have amazing features that you may want to consider:

  • Its 2000-watt AC outlet power output is sufficient to support most household appliances.
  • Its built-in MPPT controller maximizes your solar charging efficiency in any situation.
  • With the built-in OLED screen display for easy-to-read usage data, you can always keep track of the battery level and charging progress.
  • Its durable and water-resistant design makes it perfect for outdoor use, ensuring you won't be disappointed by unexpected weather changes while enjoying other outdoor activities.
  • It has multiple USB ports to allow for convenient device charging.

The backup generator for home cost will vary depending on several factors like location and the intended use. As much as the initial expenses for these generators might seem high, the benefits are worth it. Always consult a professional to choose the right generator that meets your energy needs.
