Expandable in 2.76 kWh steps, from 11 to 44.2 kWh. Its partnership with Fronius makes it a go-to for premium DC-coupled systems.
BYD Battery-Box Premium HVM supplied and installed by our SAA accredited installers across Queensland.
BYD's Battery-Box Premium HVM is a modular high-voltage LFP battery built from 2.76 kWh modules. One tower takes 3 to 8 modules (8.28 to 22.08 kWh), and up to three towers can run in parallel for as much as 66.2 kWh. BYD rates it IP55, with round-trip efficiency of 96% or better.
How it works, simply: during the day, surplus solar charges the battery instead of being exported for a few cents. In the evening the battery powers your home before you draw from the grid. LFP (lithium iron phosphate) chemistry is known for thermal stability and long cycle life.
Its long partnership with Fronius makes it the go-to battery for GEN24 Plus hybrid systems, and it suits homes that want premium DC-coupled storage that can grow over time.
For Queensland conditions: the manufacturer specifies an operating range of -10 °C to +50°C, and its enclosure rating is Indoor/outdoor (IP 55). In hot climates many systems reduce output at the top of their range, so we install out of direct afternoon sun with clearance for airflow wherever possible. With storm season bringing outages, the backup set-up (which circuits stay on) is something we'll design with you.

Products from other categories that work well alongside the Battery-Box Premium HVM.
BYD publishes a compatibility list. In Australia it's most commonly paired with the Fronius GEN24 Plus.
The manufacturer warranty is 10 years, with battery capacity remaining at end of warranty: 70%; warranted throughput: 51,230. Terms may require product registration. We register it for you.
The manufacturer lists Indoor/outdoor (IP 55). In Queensland we still avoid direct afternoon sun where possible, because heat can reduce performance, and we'll recommend the best spot during the site visit.
Eligible installations may qualify for the Cheaper Home Batteries Program discount. We'll confirm eligibility and the current amount in your quote.
Most Queensland homes suit 10–16 kWh of usable storage. We size the Battery-Box Premium HVM from your evening usage, backup goals and solar array.
Backup capability varies by model and switchboard design. We'll explain whether the Battery-Box Premium HVM covers whole-home or essential circuits for your property.
Often yes via AC coupling or a hybrid inverter upgrade. We assess your current inverter before quoting the Battery-Box Premium HVM.
