Are Home Batteries Safe? The Data, Not the Headlines
NMC (Tesla Powerwall) can experience thermal runaway at ~210°C. LiFePO4 (all AGAIC batteries) threshold: >270°C, and it does not release oxygen when heated — fires self-extinguish.
Real Statistics
Fire & Rescue NSW (2022–2023): 37 lithium battery fires. E-bikes/e-scooters: 67 ignitions. Home battery systems (R-BESS): only 3. That is 9.2% — and most were non-CEC-approved systems installed by unqualified electricians.
AGAIC Protection Layers
- LiFePO4 chemistry — inherently non-combustible
- Multi-cell BMS monitoring
- Thermal management with auto-shutdown
- IP65-rated steel enclosure
- UN38.3 / CE / IEC 62619 certified
