At a Glance: BYD Batteries score 3.1 out of 5
Scoring is based on our solar battery scorecard which is consistently applied to each brand and battery available on the Australian market. This scoring reflects BYD’s residential LV and HV series models.
$$ Price: Based on data from Solar Choice’s network of solar installers, the average price for an installed BYD battery is $1,002 per usable kWh before any rebates deducted. This places it in the lower price category.
- Company Backing and Trustworthiness (5 out of 5): BYD has had an active presence in the Australian market since 2013 and is a well-diversified company operating globally in EVs, battery storage, and electronics. They have more than 100 staff in Australia and an established office.
- Warranty Offer (3 out of 5): The warranty includes a throughput allowance of 3 to 3.09MWh per usable kWh and a degradation guarantee of 70% after 10 years, paired with a 10-year product warranty.
- Customer Reviews (4 out of 5): Based on verified reviews through Solar Choice’s independent platform, BYD has received strong positive feedback with an average rating of 4.45 from 22 customer reviews. According to our review scoring framework, this earns a score of 4 out of 5.
- Functionality (1 out of 5): BYD batteries are stackable, are not able to be AC connected without installing a separate hybrid inverter. They also are rated at IP55, have no built-in fire suppression or thermal management, and lack modular battery balancing. These limitations reduce their flexibility and future-proofing potential.

Federal Battery Rebate Applies to BYD Batteries
As of 1st of July 2025, there is a federal battery rebate which can reduce the cost of installing a battery by around 30%. For example, based on our federal battery rebate calculator a BYD Battery Box Premium HVM 13.8 battery would receive a rebate of approximately $4,620.
This rebate can be paired with the state battery rebate in WA and the NSW VPP Rebate.
BYD’s Warranty Offer For Australian Customers
BYD supplies a 10 year warranty for their batteries which covers defects in materials or workmanship. This is commonly referred to as a ‘product warranty‘ in the solar industry.
They also provide a ‘performance warranty‘ which guarantees that their battery will still retain 70% of its nameplate usable energy after 10 years or if it throughputs a minimum amount of energy (whichever comes first). The minimum through-put in their warranty document works out to be around 3 MWh per kWh of usable energy, which would give you approximately one full cycle per day for 8 years.
In general this warranty is pretty typical of what we see offered from Chinese battery manufacturers, while some guarantee a higher percentage of retained usable energy after 10 years.
BYD have a local office in Australia to support customers seeking assistance, which is a important. Without a local office and support staff, customers can be stranded trying to contact overseas manufacturers when things go wrong.

Pros and Cons of BYD Batteries
Pros | Cons |
– BYD are a globally well-known brand and one of the biggest Electric Vehicle manufacturers – BYD are well-supported in Australia – BYD’s updated warranty terms compare well against other brands | – BYD batteries don’t have a built in inverter, so will need to be paired with a compatible hybrid inverter (e.g. Fronius) – At IP55, they are rated for outdoors but are best to be protected from the elements – Without battery balancing technology, future battery modules added to the stack will drop to the lower performance of older degraded batteries |

Reviews from Australians who have installed BYD Batteries
Don't know yet hasn't been made operational
Only brand that met my requirements, so far produces power down to 2% of capacity.
Just works well and is tiny given the power and output. Safer than the Tesla and actually works during an outage with the panels too, another main reason why I chose it and the Fronius Gen 24. Looks dapper too!
Battery Box Premium - Classed 3rd best in Australia
Happy to see what we are doing with our power and we never ran out of the Battery yet.
Review left 2 years after system installed
The batteries look and function great. I hadn't heard of BYD previously but wouldn't hesitate to install them again.
Review left 1 year after system installed
It’s a solid energy storage solution. There is minimal info provided by the battery itself other than a flashing light, so the Fronius app has all the settings & data presentation. It’s chunky though - the Powerwall is a more attractive product and was my preference.
Review left 2 years after system installed
I had a failure with the battery BMU and the replacement service was excellent.
Poor storage given overall system poor performance
