Battery System vs. Generator

Battery backup power vs. generators: which is right for you?

If you live in an area with frequent power outages, you already know the benefits of having backup power installed at your home.

Propane, diesel, and natural gas powered generators have long been the system of choice for homeowners and businesses that want to ensure that the lights stay on when the power goes out in the neighborhood. Now, an increasing number of people are considering newer, cleaner battery options like the Storz Power Batteries & Inverter controller and master whole home systems like SolArk.

Battery backup power offers many of the same backup power functions as conventional generators but without the need for refueling. Read on for a comparison of battery backup options versus conventional generators, including a review of factors like cost, fuel supply, size, and maintenance.

You can charge your backup battery with energy from the sun.

What are the savings with battery backup power?

The upfront price you pay isn’t the only cost to keep in mind. If you install a generator, you also need to buy the fuel to keep it running. Fuel costs can add up if you frequently rely on your generator – this is especially the case if you also need to pay for the delivery of fuel to your home or business. By comparison, if you install a battery for backup power, you can pair it with a solar energy system to charge it with renewable energy from the sun. This will add to your upfront cost (an average 6-kilowatt solar panel system will cost, on average 17,900.00 before incentives), but over time it can save tens of thousands of dollars on your electric bill. Even without solar, your battery might be able to save you money on your electric bill. Some utilities have TOU rates which vary throughout the day. If you have TOU rates, a battery can actually result in lower electric bills by providing an alternative source of electricity when rates are high.

Issues like fuel supply for your backup power!

The source of energy for your home backup power system is another consideration when you’re comparing your options. Generators are usually powered by diesel, liquid propane, or natural gas. Your generator can continue to run as long as you have the fuel to supply your generator, and some generators can even be connected to an existing natural gas line. If you don’t have access to a natural gas line, you should expect to refill your generator as needed. By comparison, a home battery backup system runs on electricity and can be charged either from the grid or from a rooftop solar panel system. If you design a solar plus storage system for off-grid backup power, you can recharge when the grid goes down, adding an extra layer of security for situations where you might be worried about having access to fuel for a generator. (Not all home battery systems can be recharged during power outages, so make sure that your installer knows that this feature is crucial to you.)

What is the size/power load for backup options?

When you’re comparing your backup power options, think about what you need to keep running when the grid goes down. If you just want to keep the lights on in a power outage, most batteries will do the job. Many homeowners who choose batteries for backup power are comfortable knowing that “critical loads” like power outlets, lights, and small appliances will be powered in the event of a power outage. However, not all batteries are capable of quickly discharging enough electricity to get energy-intensive equipment up and running. If your home relies on a sump pump, well pump, or other equipment that uses a lot of power to start up, you’ll need to install a Storz battery and the SolArk that is specifically intended for backup power. If you install a conventional generator, you won’t have to worry about critical loads. As long as you choose a generator that is sized properly by your installer, you should be able to keep your home or business running without issue, assuming you have adequate fuel onsite. And you generator is able to run 24 hours a day 7 days a week? Which most are not warrantied to run more than 5 hours continuous in one day.

Costs of operating & maintaining your backup power system?

Generators powered by propane or diesel can be hard to ignore when they’re running. One major advantage of a battery backup system is that it operates quietly and doesn’t burn any fuel, unlike a conventional gas-powered generator. As a result, you don’t have to deal with exhaust fumes or other polluting emissions – a win for the environment and for the air quality around you. Generators powered by fossil fuels like natural gas or diesel can also have higher maintenance requirements than battery backup options. In addition to refueling, some generators need to be run and tested regularly to ensure that they’ll be operational when you need them most.

Additional issues before you buy, compare solar & batteries to other generator options.

Diesel, propane and natural gas-powered generators are relatively inexpensive and easy to size for your property’s power needs, but there are also benefits to installing battery backup power at your home or business. When paired with solar, you can actually save money on your electric bills, and batteries offer clean, quiet power that you can’t get with a conventional generator.

If you’re talking to a contractor about installing a generator, consider getting quotes for solar systems that include batteries from Treeium Energy.
