Battery backup vs generator

There are several type of backup power systems on the market but each of them serves the same primary purpose: keeping your lights and appliances on when your power goes out. Battery backup systems are a better choice for most homes. They are expandable, portable, require no maintenance, provide clean and quiet energy.

A backup power system is ideal to maintain your critical device running when the primary source fails. According to an analysis by Climate Central the major outages grew ten times more common and weather-related outages have doubled. Worldwide there were 350 million people affected by power outages in 2021. The most common power backup systems include batteries and generators.

Battery backups

Home battery backup systems such as the Bluetti EP500, store energy which you can use to power your house during an outage. Battery backups can charge using your home electricity or a fixed or portable solar panel.

These popular devices with a variety of high-powered outputs, storage capacities, and multiple ways to recharge will keep your devices and appliances running, indoors and out. Power stations give you power at the push of a button, all without the noise, fumes, or maintenance of a traditional gasoline-powered generator.

These power generator recharge by means of electrical power, 12-volt car outlets, portable or fixed solar panels, wind turbines, hand cranks or any other power generation method you might have.

Large battery backups like the Bluetti EP500 Power Station is one of the most powerful available. It can provide up to 2,000 watts of power delivery. It has enough ports to charge 15 devices simultaneously or power large appliances like Air Conditioners, Clothes Dryer or Electric heater.


Standby generators have the option to connect to your home's electrical panel and kick on automatically when the power goes out. Or can be turned on manually once the power goes out.

The DuroMax XP15000EH Gas Powered Generator can run on both Gas or Propane. This Generator provides plenty of power with 15,000 peak watts and 12,000 running watts, this unit can handle heavy loads from lights and a refrigerator to a home air conditioner and high amperage power tools.

With a generator rated at 5,000 to 7,500 watts, you can run even the most critical household equipment, including things such as refrigerator, freezer, well pump, and lighting circuits. A 7500-running watt generator can run all these appliances at once.

Battery backup vs. generator: Which one is best?


Battery backups tend to be more expensive but do not require you to keep fuel in stock to power them back on. The price of purchasing and installing a large standby generator can range from $7,000 to $15,000 and this does not include any modifications that might need to be done to your home as installing a concrete slab to mount the generator outside your home and purchasing large containers of gas to keep them running.

If needed a Battery backup generator can be installed permanently and use a solar panel to maintain the battery during extended power outages.


Battery backups run independently, don't produce any emissions and don't require any ongoing maintenance. If powered by a Solar Panel this device can be left on standby for years. On the other hand, power generators require fuel and spark plug changes to keep then running.

A Generator maintenance checklist includes the following:

  • Clean Generator. Clean with Towels and a Degreaser Every 1 Year and Check for Leaks.

  • Change Oil after 25 Hours of use or every year that is not in use

  • Change Oil Filter

  • Change Air Filter

  • Change Spark Plugs

  • Check Fuel Filter

  • Check Battery

  • Add Fuel Stabilizer

Most people know the frustration of being left with out power and its consequences, we depend on power on our daily lives and investing on a power generator is always a good idea.
