Home Battery Backup could store electricity energy locally for later consumption, also known as “Battery Energy Storage System” (“BESS” for short), with rechargeable batteries, typically based on LiFePO4, controlled by a computer. they coule be your power backup when it is blackouts or in an off-the-grid lifestyle.
If you live in an area with frequent power outages, you already know the benefits of having a backup power supply for your home. Before propane, diesel, and natural gas-powered generators have been the system of choice for homeowners and businesses that make the lights on when the power goes out. Now, more and more people are considering the newer and cleaner battery options.We could get the advantages of new energy by compare it with old models through the following aspects.
1.The roughly cost for the Home battery backup costs(The Home battery backup costsdepending on home size )：
Compared to generators, battery backups do have a higher upfront cost, and you may need more than one battery depending on the size of your home and your energy needs. For the average medium-sized home, an initial battery backup investment can range from $10,000 to $20,000—this is just an estimate for a small battery system that could supply energy for about a day. If the same medium-sized home is integrating a battery backup system with their solar panel system to generate power, upfront costs can increase to about $20,000 to $40,000.
2.The maintenance costs on 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. Not to mention, you need to store the fuel somewhere in your home.
By comparison, if you install a battery backup power in your home, 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 (a smaller-than-average 6-kilowatt solar panel system will cost, on average, $16,560 before incentives), but over time it can save you 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 time-of-use (TOU) electric 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.
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.)
Size/power load for backup power 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 battery 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
