Battery series · BYD · 4 sizes, all CEC-active
4 sizes from 5.12 to 12.8 kWh usable, from below the smaller-home band to the smaller home band. This page is for picking the size.
Each size is its own CEC listing with its own page. Household bands are the owner’s guide; rebate fit is against the WA scheme’s cap.
WA rebate fit: Under the cap
Household band: Below the smaller-home band
Full specs , 5.12 kWhWA rebate fit: Under the cap
Household band: Below the smaller-home band
Full specs , 7.68 kWhWA rebate fit: Closest fit to the cap
Household band: Smaller home (10 to 15 kWh)
Full specs , 10.24 kWhWA rebate fit: Over the cap
Household band: Smaller home (10 to 15 kWh)
Full specs , 12.8 kWhThe WA Battery Scheme pays $130 per kWh on the first 10 kWh, capped at $1,300. Capacities under 5 kWh receive nothing, and every capacity from 10 kWh up receives the same $1,300. A larger battery does not earn a larger rebate. Whether a particular product qualifies also depends on it being Synergy-approved. “Over the cap” does not mean you should not buy it; the extra capacity is simply at full price. Figures come from each size’s own CEC listing; SBP holds no verified per-size pricing for this series.
The Battery-Box Premium HVS is the compact sibling to the HVM, for installations with limited space or smaller capacity needs. It uses 2.56kWh modules (slightly smaller than the HVM's 2.76kWh) and scales from 5.1kWh to 12.8kWh in a narrower footprint.
The HVS operates at a lower voltage range (102-153V vs the HVM's 204-358V), which makes it compatible with a different set of hybrid inverters. That suits inverter pairings where the HVM's higher voltage is not supported.
Build quality is the same as the HVM: LFP Blade Battery cells, same warranty terms. The choice between HVS and HVM usually comes down to inverter compatibility and space rather than performance.
For Perth installations, the HVS offers good value for typical household needs. A 10.2kWh system (4 modules) covers most evening use while staying physically compact. The modular design allows starting at 5.1kWh and adding modules later.
