How long will a powerwall last?

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.

 

But in a market full of options, it may not be clear how they stack up, especially with extended power outages.

 

Currently, there are no solar-plus-storage systems on the market that can fully support the average U.S. electricity use during a full-day power outage. But customers can rely on them for some basics, analysts say. 

 

"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. 

 

Many households use electric stoves for most of their cooking to save electricity. Mild temperatures mean no need for climate control, but this consumes too much electricity anyway. However, in many cases, power outages can be dangerous for many people.


How long will my battery system last?

 

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.

 

Currently, two Powerwalls would need to be purchased in order to meet 100% of a home's clean energy supply and ensure at least 24 hours of power during an outage. recent data also shows that many homeowners installing energy storage systems are opting for two batteries rather than one to increase backup capacity. 

 

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.


Since 2003, BSLBATT provides electric energy more efficiently and reliably as best solution. Powerwall charges by day and powers at night for residential solar system with compact, affordable and easy installation features.
