Electric and solar home battery backup systems For instance, air condition or heating may have to be sacrificed in order to avoid draining the battery too quickly. To last more than a few hours, home energy consumption may need to be reduced. Unless a large battery system is installed, they can support critical loads for only about a day. In addition to the higher upfront cost of about $10,000 to $20,000 for a medium-sized home, most batteries can only run for a short period of time.
Though home batteries have a lot of advantages, there are also some drawbacks.

The lack of fuel also means the air around you remains free of pollutants, benefiting the health of your family. Relying on the electrical grid also means less fuel is released into the atmosphere, making home battery backup systems even more attractive to environmentally-conscious homeowners. When prices are high, use the battery system instead of the main grid and watch your utility bill go down. Simply charge the home battery backup system when the utility prices are low. Rather than paying for fuel to power the engine, batteries store energy from the electrical grid, which is much less expensive.Īdditionally, if prices for your utilities tend to cost less at certain times of the day or week, you could use backup batteries to save money. Investing in a home battery backup system is a lot like investing in an electric car: the initial investment is higher, but they are easy to maintain and inexpensive to operate. Quiet, smooth, and effective, batteries are an excellent option for homeowners who experience frequent outages of a short duration, typically anywhere from a few hours to one day. Home batteries like the Tesla PowerWall connect to the electrical grid rather than fuel sources, providing clean and easily-accessible power. Therefore, if you live in an area prone to natural disasters, you might consider options that don’t rely on fuel. Fuel-powered generators require truck delivery of propane or diesel or natural gas supply lines, both of which may be hindered in a disaster. Additionally, in extreme weather, the source of fuel may be vulnerable. Though reliable under most circumstances, fuel-powered generators may be prone to breakdowns under extensive usage. Additionally, if you own an electric vehicle, you would not be able to charge it during a power outage. Fuel-powered engines can be noisy and less environmentally-friendly than other options.

In addition to the money you will need to put into maintaining the generator, you will also need to exercise the generator once a week. This type of generator carries a few disadvantages. For a medium-sized home, costs range from $7,000 to $15,000. Though they may cost a few hundred dollars a year to maintain, fuel-powered generators have the lowest upfront cost. They are reliable and able to provide power in all weather conditions. If you live in an area that experiences extended power outages lasting more than a few hours, traditional fuel-powered generators may be the safest bet.įuel-powered generators offer several advantages over home battery backup power. This is the most common type of backup generator out there. When power from the electrical grid shuts off, the generator automatically taps into a fuel source and starts up, bringing power back to your home.
Traditional standby generators are powered by natural gas, liquid propane, or diesel. Consider your household’s energy consumption patterns and your biggest needs during a power outage when making a decision.
Some homes are entirely off the grid and may require a generator that relies on fuel, battery power, and solar energy. If you experience longer outages, you may need a traditional standby generator. If you experience short but frequent outages, a home battery backup system could be the best option. What type of generator you buy depends on your individual circumstances. For stronger protection, some people opt for a combination of solar and electric power, or even solar, electric, and fuel-based power. An increasing number of people, however, are looking into home battery backup systems such as the Tesla PowerWall as an alternative. Traditional backup generators are fuel-based and reliable. There are a range of backup generators on the market that rely on different power sources. Home battery backup systems can provide a lot of the same benefits, but can have different drawbacks. They provide a layer of security and comfort for your family and ensure you are always prepared for a disaster. If you live in an area that experiences frequent power outages, you already understand the importance of backup generators.
