The past year 2020 has seen frequent hill fires in many parts of the world. In the United States, while fires are part of California's natural landscape, extreme weather exacerbated by climate change has made wildfires even worse.
Back in January 2019, a California state order went into effect requiring all new homes to include solar. The massive fires that brought the world to attention last year also forced more customers to seek resilient energy solutions.
Maintaining power supply in severe weather conditions or unfortunate accidents is a concern for most homeowners. Fortunately, it can be remedied by purchasing BSLBATT Powerwall. But in a market full of choices, many people do not know how to choose the Powerwall suitable for their home use, or do not know how many Powerwalls should be stacked to satisfy their home electricity consumption.
"Depending on the size of the battery, these home solar plus storage systems can add a degree of resilience: keeping the lights on, the Internet running, food from being destroyed, etc. It's definitely valuable," says Bella Cheng. regional sales manager for BSLBATT.
So before making a choice, we must understand how long a Powerwal can last for power usage!
Some batteries allow for longer backup times. For example, the BSLATT Powerwall's 13.5 kWh hour capacity at 10 kWh is higher than most comparable home energy storage batteries. However, these systems have essentially the same power rating (5 kW), which means they provide the same "maximum load coverage".
Typically, during a power outage, the maximum power will not reach 5 kW. This load is roughly equivalent to running a clothes dryer, microwave oven and hair dryer at the same time.
An average homeowner will typically consume a maximum of 2 kW during a power outage, and an average of 750 to 1000 watts during a power outage. This means that the BSLBATT Powerwall can last for 12 to 15 hours.
At present, some areas in Australia will choose a 7.5Kwh Powerwall as a backup power source, but some European countries prefer residential batteries with a capacity of 10Kwh or more as a backup battery system, and some areas in the United States usually buy two Powerwalls to ensure During a power outage, it can maintain a 24-hour power supply. It should be noted that it is impractical to use BSLBATT Powerwall (or any other type of battery) to run the load of the entire house, although the capacity of our energy storage battery has been expanded to 15Kwh or higher, Currently, there are no solar -plus-storage systems on the market that can fully support the average US electricity use during a full-day power outage. But customers can rely on them for some basics, analysts say. So, this is not the way most people use Powerwall !
BSLBATT has seen an influx of storage demand from existing customers looking to upgrade their systems, as well as new customers requiring batteries from the start. However, in terms of how long a system can last, it depends on the amount of power used by the home, the size of the home and the weather conditions in your area.
"Some of our customers may be able to use one or two batteries for an entire home backup, and then in other cases it may not be enough." said Scarlett Cheng, energy storage sales manager for BSLBATT.
To solve the problem of stable power supply during power outages, technology teams from many manufacturers are working to integrate conventional generators and demand-side management with their storage + solar systems to create a residential autonomous power system.
Because conventional generators use fossil fuels, this solution is not as clean as solar and storage alone, but can provide greater reliability during extended power outages.
Whichever solution customers choose, they say most people are aware that climate change is exacerbating the effects of natural disasters, whether they live in California or not. That's an encouraging change.
"There's no reason to sit in your house and not know when the utilities are going to turn off the power or when the power lines are going to drop. Frankly, it's a little outdated," Scarlett says.
As a society, not only in the U.S. but globally, we all deserve and have the right to demand better service. And now, more and more people are able to go there and get better service.
