Can I Install a Home Battery Anywhere?
No. In Australia, battery energy storage systems (BESS) must meet AS/NZS 5139:2019, Western Power’s WA Electrical Requirements (WAER), and the manufacturer’s guidelines. At Australis Solar, we ensure every system meets these standards so you can enjoy reliable, safe and rebate-ready battery storage.
Locations Where Batteries Cannot Be Installed
According to AS/NZS 5139 and GSES guidelines, batteries must not be installed in the following areas:
-
Inside habitable rooms – bedrooms, living rooms, kitchens, or any frequently occupied space.
-
Ceiling spaces or wall cavities – restricted due to heat and ventilation issues.
-
On roofs – unless specifically approved by the manufacturer.
-
Under stairwells or evacuation routes – must not obstruct safe exits.
-
Within 600 mm horizontally or 900 mm below any window or vent into a habitable room.
-
Within 600 mm of an exit door (including garage doors), unless there is >1000 mm clear passage in WA.
-
Near other appliances such as stoves, motors or heat pumps – keep ≥600 mm horizontally or ≥900 mm above. Inverters directly connected to the battery are excluded from this rule.
Where Can You Install a Solar Battery in Perth?
Safe and compliant options include:
-
External walls – ideally shaded or under eaves, on a non-combustible surface or with a compliant fire barrier.
-
Garage or shed – permitted if ventilation and clearance rules are met. Vehicle impact protection (e.g. bollards) may be required.
-
Dedicated battery enclosures – purpose-built, ventilated and fire-rated cabinets designed for BESS.
Clearance Requirements
Clearances vary by brand and model. The stricter of AS/NZS 5139 or the manufacturer’s specification must always be followed:
-
Windows & vents into habitable rooms: ≥600 mm horizontally, ≥900 mm below.
-
Exits: ≥600 mm from doors (with WA exception noted above).
-
Other appliances: ≥600 mm horizontal or ≥900 mm above.
-
Fire barriers: If the wall behind has a habitable room, install a non-combustible barrier (AS 1530.1) extending ≥600 mm each side and ≥900 mm above. If the unit is within 900 mm of the ceiling, extend the barrier across the ceiling by ≥600 mm.
-
Manufacturer airflow/service space:
-
Sigenergy SigenStor – keep 300–600 mm free for heat dissipation; never block front covers.
-
Fronius Reserva – ≥300 mm side clearance; suitable for indoor or protected outdoor use (not exposed rain).
-
Fronius GEN24 Plus – IP66, outdoor-rated; PV Point and Full Backup functions available depending on model.
-
Why Compliance Matters in WA
Failure to meet standards can:
-
Void warranties and home insurance.
-
Increase risks of overheating or fire.
-
Breach Western Power and Synergy VPP participation rules.
