BYD Battery Box

Share This Post

BYD is a titan in the electric vehicle and battery industry. They have rapidly built their company into China’s largest rechargeable battery manufacturer and the fourth largest in the world. As such, BYD Battery Boxes remain one of the most sought-after energy storage solutions for both residential and commercial purposes.

BYD Battery Boxes are a range of solar battery storage devices that are sold by a number of large solar installation companies due to the flexibility and expansion capabilities of their extensive line of high- and low-voltage batteries.

If you have been considering this product, it’s no surprise, as many consider it to be one of the best solar batteries in Australia. But if you want to learn more about it and how it compares to the competition, continue reading below to find out.

What is a BYD Battery Box?

BYD Battery Boxes are a line of solar battery products ranging from residential to commercial applications. BYD Battery Boxes are used for backup power and off-grid power supplies, optimising renewable energy-efficiency, and everything in between.

Emergency power and off-grid utilisation are among the most common applications for the BYD Battery Box. The battery’s high discharge capacity enables its operation even when connected to the main electrical grid. The BYD Box can supply power to off-grid homes, remote cabins and even commercial projects with very sensitive loads.

Optimisation of electricity usage is another common application of BYD Battery Box customers. With the government pushing the switch to renewable energy, which comes with subsidies and rebates, more and more people are looking to increase their power generation self-sufficiency and efficiency. Continued use of renewable energy solutions such as this becomes more economical in the long run.

Of course, scenarios and circumstances where the battery box can be used are not limited to those mentioned above. There are many instances in which having an energy storage solution is beneficial beyond electricity cost, especially since you can start with a lower capacity BYD Battery Box and add capacity at any time throughout the product’s life.

Who Makes BYD Battery Box? 

BYD Battery Boxes are made by BYD Co. Ltd. (“Build Your Dreams”) which is a Chinese conglomerate manufacturing company based in Shenzhen, Guangdong, China, founded in February 1995. The company has two primary subsidiaries, BYD Automobile and BYD Electronic, with the latter manufacturing the BYD Battery Box. 

BYD Co. Ltd. is widely known for manufacturing fully electric and hybrid motor vehicles. They also manufacture battery-operated bicycles, forklifts, solar panels, and rechargeable batteries such as the BYD Battery Box.

The company was publicly listed on the Hong Kong Stock Exchange on 31 July 2002 and initially competed in the Chinese rechargeable batteries market against Japanese imports. According to BYD’s sales figures, they have surpassed Tesla for the highest electric vehicle sales globally.

The company rapidly grew after capturing more than 50% of the world’s market for mobile phone batteries. It is now the largest Chinese manufacturer of all kinds of rechargeable batteries and the fourth worldwide. In 2010, BYD ranked highest in Bloomberg Businessweek’s Tech 100 List, which included other large and fast-growing tech companies.

What Types of BYD Battery Boxes are Available?

BYD Battery Boxes come in three distinct lines: the High Voltage (HVS/ HVM/ HVL US), the Low Voltage LVS, and the Low Voltage LVL.

All BYD Battery Box models use a Lithium Iron Phosphate (Cobalt-free) battery and are suitable for use on-grid, as on-grid back-up, or off-grid. All have an operating temperature of -10°C to +50°C.

BYD Battery Box Reviews

BYD solar batteries have received an average customer rating of 4.7 stars out of 5 on SolarQuotes

“System got installed end of April 2022. It’s still early days, the installation went smoothly and the battery performance is excellent so far. Tested it it by running the Air-conditioner during the night for +- 2 has and mornings. Not once I had to use power from the grid. So far I am vary happy with the purchase.”Wolfgang, SolarQuotes

“They are big boxes but look neat and tidy. Able to supply 5 Kw from battery. Batteries are not quite fully charging in very wet weather but easily charge on sunny days.”Mo, SolarQuotes

“18kW solar & 22kW battery system. Solar has generated between 40kWh (rainy day) to 140kWh (sunny day) with the majority being exported. Nightly battery consumption is 20%. System has not been run to capacity yet as only 2 months since install and hasn’t been a hot or cold enough day to run air con. […] The batteries run silently.”Gordon, SolarQuotes

“the b-box is nice and discreet. time will tell the ultimate reliability. The modular ‘all in one’ set up is a big selling point for me.”Mat, SolarQuotes

“The fact if needed more batteries can be added at a later date was a big selling point.” Eldred & Joyce, SolarQuotes
