Before the advent of Home Solar Battery Backup Systems, propane, diesel and natural gas generators have always been the systems of choice for homeowners and businesses to ensure that electrical appliances remain in operation during power outages. If you live in an area with an insufficient power supply or frequent power outages for a long time, you will know the benefits of installing backup power at home. Now, since Tesla launched the Powerwall, more and more people are turning to cleaner homeenergy storage systems. Although the use of homeenergy storage systems in the world is still very small, they will eventually become the trend of the world! In some areas, severe weather often occurs, such as storms, which often cause their grid systems to cut off power. The grid will not repair and supply electricity until the storm disappears. So homebackup batteries can change this situation very well! "A storm can mess with a power line, knocking out power for hours, but our Internet, furnace, and refrigerator stay on," says Phil Robertston of Woodstock, VT. Wouldn’t it be great if you don’t have to worry about power outages? According to data from the Solarquotes Blog, the latest data show that Vermont experienced an average of 15 hours of power outages in 2018, making Vermont the second state with the longest power outages in the United States. How Long Do Home Battery Backups Last? Home batteries have a lot of advantages: they are cleaner, quieter, more environmentally friendly, and help you save money on your utility. But when push comes to shove, are home batteries as effective as fuel-powered generators? Factors that determine the duration of home batteries 1. capacity of home battery backup power The capacity is measured in kilowatt-hours (kWh) and can vary from as little as 1 kWh to over 10 kWh. Multiple batteries can be combined to add even more capacity, but a 10 kwh solar system is usually what most homeowners install. For example, one of theenergy storage batteriesof BSLBATT can store 15kWh. Home batteries at the high end of the spectrum can usually last for 1 to 2 days, depending on the household’s power usage. Of course, reducing energy use during power outages will extend battery life. 2. Determining your home’s electrical needs Before choosing to buy a home energy storage battery, you must first evaluate the electricity consumption of your home. For example, the electricity consumption in a Canadian home is about 30-35Kwh per day, but a home in the United States can be as high as 50Kwh, so they may choose to buy 2-3 home batteries that can guarantee the normal use of their electrical appliances all night, so it is very important to choose a home energy storage system according to your own household electricity consumption. Different electrical appliances require different energy, not only to run but also to start. For example, a refrigerator may need 700 watts to keep running, but it needs 2,800 watts to start. To determine the necessary capacity of the home backup battery system, you should add up the power required to start each device in the home. Turning off unnecessary electrical appliances may extend the life of the home battery backup system by hours or even days. It is also impossible for your home to be completely disconnected from the grid. Home energy storage systems can alleviate your expensive electricity bills, or are the best alternative in the event of a power outage. If your home is not connected to the grid, when you generate energy without you when you use that much (ie: any time the sun goes down), your electricity will stop working. How much is a whole-house battery backup? The cost depends on the type of hybrid or solar inverter deployed and the capacity of the battery. Household batteries start at $4,000 and can go up to $20,000 or more, depending on their kWh or kWh (a measure of storage capacity). According to experience, the price of a typical battery is between 1,000 and 1,300 US dollars per kilowatt-hour. As the demand for homebattery systems becomes widespread, its cost is expected to drop. Tesla’s Powerwall 2.0 is a 269-pound lithium-ion battery. The entire device costs US$5,500, including the inverter, and stores 13.5 kWh of energy. The price of Tesla Powerwall 2 is approximately US$13,300, so it is approximately US$1,022 per kWh. The battery of the LG Chem RESU H series can hold 6.5 kWh of energy, the cost is about 4,000 US dollars, about 795 US dollars per kilowatt-hour, but the inverter is sold separately. This price is very close to Tesla. Sonnen’s smallest battery is 4 kWh, and the cost including installation is approximately US$10,000, which is approximately US$1220 per kWh. Each additional 2 kWh battery module adds approximately US$2,300. Enphase has a 1.2 kWh module, the price is about 3,800 US dollars, each additional one is about 1,800 US dollars. Each battery module has enough energy to power small loads. To match the size of the Powerwall, you need 11 batteries. Our BSLBATT Home Energy StorageSeries 48V Lithium Batteries have a capacity of 2-10Kwh, and the price of each battery is about 2500-3000 US dollars. It is also one of the most affordable and reliable battery systems on the market. Our 48V home energy storage batteries are compatible with most inverters on the market. Is house battery backup worth it? There is a lot of information that indicates that for any homeowner who wants to use solar energy, a home battery backup power supply is the best choice. Some areas have been facing rising energy prices. The use of home energy storage batteries may require a lot of investment at the beginning, such as battery costs, installation costs, etc. However, from the perspective of long-term development, household energy storage systems, the benefits are many! 1. For the environment Home energy storage systems can use the cleanest energy-solar energy to power your home appliances. In some European countries, they prefer to use the sun to generate electricity. After installing home backup energy storage batteries, your solar energy utilization rate will change. Get higher. 2. Protect your home from power outages The main reason for getting the backup battery option is that it allows you to be protected in the event of a power outage. During a power outage, whether due to maintenance or natural disasters, if a natural disaster causes a long-term power outage, the backup battery option can protect your home. Your solar panel can charge your solar battery to ensure that your home continues to supply power. 3.Save electricity bills Electricity bills are rising year by year, and energy costs continue to increase. With a backup battery solution, you can lock yourself at a lower energy rate and avoid peak charging. Even if your solar panel system does not generate electricity, your home will still run on the energy stored by the battery. In Europe, many countries will encourage the use of home energy storage systems and will give them some subsidies. After users purchase solar systems, they will even recycle the excess electricity from the household solar systems, alleviating most of the electricity bills. 4. No Noise Pollution Unlike generators, solar panels and battery storage systems don’t create noise pollution that will bother your neighbors. This is a unique benefit, and is a great way for anyone who currently has a generator to update their system. How Many Batteries Are Needed to Power A House? Under normal circumstances, we can measure the battery capacity or the number of batteries we choose based on our average annual electricity consumption. For example, in Australia: an ordinary household uses 19kWh, 30% of which is used during the day and 70% is used at night, then uses about 5.7 Kwhduring the day and about 13kWh at night. Therefore, simple mathematical calculations show that on average,Australians need about 13kWh of solar cell storage to offset all their nighttime use. Therefore, when buying a home energy storage battery, choosing a battery of 10-15Kwh is completely enough for their household appliances to be powered on overnight, but in the United States, the electricity consumption of some four-person households can be as high as 50Kwh, then according to the above calculation, A 10Kwh battery is not enough, they may need to spend more to buy 2-3 household batteries! Types of Battery-powered Solar Power Systems: Off-grid or Hybrid? The battery for solar energy can be used in two types of photovoltaic systems: off-grid (isolated system or autonomous system) and hybrid. For you to really immerse yourself in the issue of energy storage, it’s important to understand that there are two types of solar battery storage configurations you can choose for your home: Off-Grid Systems In the off-grid solar energy system, your property will not be connected to the electricity grid, therefore 100% of your electricity will be generated by your solar panels and stored in solar batteries for overnight use. Advantage of Off-Grid solar energy: Your property is your own electrically self-sufficient "island". No meter. No electricity bills. The disadvantage of Off-Grid solar energy: Full off-grid configurations are very expensive – the total cost of the system for a middle-class home ends up being around R$65,000 or more. Most off-grid solar power owners live in isolated areas where there is no other option but a diesel generator. Hybrid Solar Energy System – Solar UPS Hybrid photovoltaic systems are configured so that your property is connected to the electricity grid, in addition to storing solar energy in batteries. Hybrid systems prioritize the use of electricity stored in their batteries over grid electricity. Advantage: Cheaper than an off-grid solar power generator as you will need fewer batteries for solar power. It can be programmed to use the stored energy when it is peak hours at the distributor and allows you to have several hours of autonomy if the distributor’s network has any problems. Disadvantage:You still depend on the distributor’s power grid. And What is The Best Solution? Off-Grid, Hybrid, or On-Grid? It really just depends on your goal and budget: On-Grid Solar (Battery-Free Solar Power System) allows you to produce your own electricity from sunlight and reduce your electricity bill by up to 95%. Off-Grid Solar: Independence! It allows you to generate your own electricity from sunlight and never run out of power or pay a utility bill again. Hybrid Solar: This allows you to produce your own electricity with sunlight, reduce your electricity bill by up to 95%, and provides greater security: if the grid runs out of energy you still have your solar batteries.
