About BYD, Solar Batteries

BYD solar batteries review

BYD stands for Build Your Dreams - and among BYD's many dreams is being the no.1 company for solar battery storage.

Situated in China, BYD has an impressive pedigree. Founded back in 1995 and listed on the Hong Kong Stock Exchange in 2002, it started out as a battery manufacturer and entered the automobile sector in 2003. That's the opposite of Tesla, which started out on electric vehicles and then moved into solar battery storage.

The USD $16 billion dollar company has built many of the quarter of million plus electric buses running around China (and many used elsewhere) - so it's had plenty of practice in developing EV and battery technology that gets a good workout. While many Australians may not have heard of the company, it's also one of the world's largest lithium-ion battery manufacturers.

BYD B-Box

In 2017, BYD brought the B-Box to Australia's battery battleground.  The BYD-produced battery modules are based on lithium-iron phosphate chemistry, which is currently the safest technology to use in a home energy storage system. 

Compatible with SMA, Goodwe, Victron, Sungrow, Selectronic and Solis hybrid inverters, it's a modular system available in varying capacities. For example, the BYD B Box Pro 13.8 offers 13.8 kWh of useable storage capacity, which is a tad more than the Tesla Powerwall. 

What is also more than the Powerwall is its weight - significantly so (175kg vs 122kg), but home batteries aren't the type of thing you have to move around once in place.

If 13.8kWh of useable capacity isn't enough for you - up to 32  B-Box Pro 13.8 battery systems can be connected in parallel. But if you need that much storage for a household, then the police will probably also take an interest in what you're doing with it.

The cost per total warranted kilowatt hour for the BYD B Box 13.8 is around the $0.22 (+ inverter cost) mark, so it's quite competitive on price.

One of the standout features of the BYD B Box battery system is its power output - a very impressive 12.8kW that leaves just about all other solar battery manufacturers in its dust. A compatible inverter enables DC coupling to solar and backup power during blackouts, and it can also be AC coupled

However, if you're thinking of installing it outside - you're out of luck. It's only rated for indoors. 

BYD warrants the B Box will retain either sixty percent of its usable capacity at ten years from the invoice date, or for a minimum output energy of 42.7 megawatt hours. The company has an office in Mascot, NSW, so any warranty issues should hopefully be sorted out rapidly.

Additional specifications of the BYD B Box can be located on our solar battery comparison table.
