The 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.

The SOFAR BTS E6 is a high-voltage modular LFP battery designed to pair with SOFAR's HYD hybrid inverter range. The 5.12kWh stackable modules scale from 5.12kWh to 20.48kWh, which covers most residential needs. SOFAR has grown in the Australian market since 2018. A Melbourne office handles local warranty and support over an Australian phone line. The BTS E6 offers competitive pricing per installed kWh, which puts it within reach of a range of household budgets. The SOFAR Smart Energy app shows real-time solar generation, battery state, and household consumption. The system supports backup power with automatic switchover during grid outages. For Perth installations, the IP55 rating is suitable for garage or sheltered outdoor mounting. The 95.8% round-trip efficiency is competitive, and the modular design allows starting at 5.12kWh and adding capacity later.
