BYD Battery-Box HV

The Battery-Box HV is the first real high voltage battery that comes with a flexible and modular design with no cables inside. One Battery-Box HV contains 5 to 9 battery modules B-Plus H 1.28 in series connection and it reaches up to 11.52 kWh usable capacity.

The HV is a modular system, so the parallel connection of up to 5 (the maximum supported) identical Battery-Box HV allows a theoretical maximum capacity of 57.6 kWh. Have a look at the graph below to see how rapidly the company is moving. Fantastic signs for domestic and commercial solar systems alike.

The BYD Battery-Box HV

These high voltage, modular battery boxes are able to carry from 5-9 battery modules inside them, depending on which model you pick. BYD offer a 10 year warranty – we’ve reached out to them for more details (as I understand it they expect 60% capacity after 10 years) so watch this space. The enclosures are IP55 rated and all boast an impressive round trip efficiency of >95%.

BYD B-Box Australia in 2021 – Price, Review.

2021 Update: We’ve also written about the BYD Battery-Box HV – click to learn more!

BYD B-Box Australia – we wrote about the B-Box from Chinese manufacturer Build Your Dreams a few years ago and how the BYD B-Box compares to the Tesla Powerwall 2 – it has continued to see a lot of interest over the past three years so we have an article today with some more detailed information about the BYD’s product range, pricing, and some live data from the field to see how the B-Box performs in real-world settings.

BYD B-Box Australia – Price

The B-Box comes in high voltage (HV) and low voltage (LV) – with the B-Box LV Residential the most popular energy storage device BYD sell. It has a higher IP rating than the Pro variant, and separate circuit breakers for each battery module. 

It comes in four different sizes – 2.56kWh (2.45kWh usable), 5.12kWh (4.9kWh usable), 7.68kWh (7.35kWh usable), and 10.24kWh (9.8kWh usable). All four variants are IP55 rated and modular – meaning depending on the case you purchase you will be able to start small and upgrade if need be. You can get a total capacity of 57.5kWh which would work for light commercial usage. 

We’ve got some pricing available from some sites below, but please feel free to contact us if you’d like a hand with quoting of getting access to a specific B-Box:

BYD B-Box Pro 5.0 – 5.12kWh – $5315.00 ex GST

BYD B-Box LV 5.12kWh battery module – $4512.48 inc GST (at Queensland Solar and Lighting)

BYD B-Box Pro 13.8kWh 48V battery – $9,000 delivered (excluding install)

BYD B-Box Australia – Review

Things we like about this battery – it has blackout protection, is suitable for single phase and three phase power. They have local Australian support and offer a 10 year manufacturer’s warranty. The batteries are modular and can be partnered with inverters such as GoodWe and SMA Sunny Island for on-the-go monitoring. You can use them on or off-grid. 

The B-Box HV received the “PV Magazine Top Innovation Award” in 2017 and BYD’s factory is currently producing a massive 8.6gigawatts, 8 times larger than Tesla’s Nevada Gigafactory – so there’s plenty of room to grow.

Battery Test Centre have a live feed of a B-Box hooked up to a SMA Sunny Island Inverter and it’s performing very well so far – click here to view the feed and see what real-life application of the battery looks like. The B-Box 25 (2.45kWh usable) they’re using has a DOD (depth of discharge) of 95.7% and a BMS (battery management system) to ensure it remains safe when charging/discharging. The battery is showing 97%+ efficiency. 

The B-Box differs from ‘conventional’ lithium ion batteries (such as the Powerwall) as it uses LFP technology – lithium iron phosphate (LiFePO 4) battery  – a rechargable lithium-ion battery, which uses LiFePO 4 as a cathode material, and a graphitic carbon electrode with a metallic current collector grid as the anode. This is widely recognised as a safer technology than lithium-ion which was built for smaller devices like mobile phones or mp3 players.

BYD in 2021 – Electric Car BYD EA1

I know this isn’t technically related to the BYD B-Box, but I love this news so much I thought I’d share:

BYD has revealed a revolutionary new electric hatchback with a 1000 kilometre range and sub 3.0-second acceleration that will be sold in Australia.

Revealed at the 2021 Shanghai Motor Show, the BYD EA1 hatchback rides on the brand’s new e-Platform 3.0 and receives power from the new 800-volt “Blade” battery claimed to be capable of receiving 150km worth of charge every five minutes.

No word on price yet but I’m confident it’s going to be very competitively priced! Wonder what battery they’ll have in them? 🙂

BYD B-Box Solar Battery vs Tesla Powerwall 2

Edit: As of February 2018 we have a new page with more information about the BYD B-Box in Australia – please click here to read it. 

China’s BYD (Build Your Dreams), the largest producer of lithium-ion rechargeable batteries in the world, have released a new solar battery, the BYD B-Box, to compete with the likes of the Tesla Powerwall, Redflow and LG’s line of energy storage. The media launch was in late March in Sydney and BYD have signaled their intent to move aggressively into the Australian market. They’re a gigantic company based in Shenzhen with a market cap of $22b (Warren Buffet owns 8.25% of the company) and are bigger than Tesla (their battery factory is currently producing a massive 8.6gigawatts, 8 times larger than Tesla’s Nevada Gigafactory) , so they certainly pose a very realistic threat to the incumbent solar battery producers.

BYD B-Box Models

The B-Box comes in high voltage (HV) and low voltage (LV) – with the B-Box LV Residential the solar battery we expect to be the most interest to Australian consumers. The LV model comes in four flavours, listed below (please note you’ll also need to purchase a compatible inverter to go with the B-Box – but given the size of the company we expect that won’t be much of a problem):

BYD B-Box Price in Australia

BYD’s previous solar battery, the Mini, was a 6kWh system which retailed for around $11,000 AUD. Technological improvements and component price decreases means that the B-Box 10 will cost $8,500 AUD for an a 10kWh system, representing a reduction in price per kWh of over 50%. Liu Xue-liang, sales manager has indicated that BYD will be throwing their considerable heft behind the product and BYD’s electric car business, being quoted as saying: “This is not just a new product, it is a new industry,”.

BYD B-Box vs Tesla Powerwall 2

In contrast to the Bbox prices previously outlined, the Tesla Powerwall 1 was a $10,000 system at 7kWh and the Tesla Powerwall 2 will feature a 14kWh battery at $8,000 AUD – slightly more impressive figures for their second gen offering.

According to Adam Clements from Solar Australia the price declines in solar mean a 5.5kW PV roof solar system, inverter, and 7.5kWh BYD battery costs around $15,00 and pays for itself over eight years.

The BYD can have an AC or a DC inverter, as opposed to the AC only Powerwall 2. The B-Boxes also have very high power output, with the B-Box 10 able to give 10.24kW of power continuously (this would empty the battery in less than an hour). In comparison the Powerwall 2 can only output 5kW so if you were using it off-grid or as a backup for power-hungry devices, keep this in mind.
