Safe, Compliant, and Built for Sunshine Coast Homes
More homeowners across the Sunshine Coast are adding solar battery storage to their systems — and it’s easy to see why. Batteries help store excess solar energy, lower power bills, and make better use of your solar setup day and night.
But before installation, it’s important to understand the rules and standards that apply in Queensland. These regulations ensure your battery is installed safely, away from heat, gas fittings, and exits, and in full compliance with Australian Standards.
At SolarWide, we follow every requirement set out under Queensland’s Electrical Safety laws and national wiring standards. That means every battery we install is safely positioned, fully compliant, and designed to perform reliably through our region’s warm, humid conditions and everyday energy loads.
Read This First
All solar battery installations in Queensland must comply with:
- AS/NZS 5139:2019 – Electrical installations for battery energy storage systems
- AS/NZS 3000:2018 – Wiring Rules
Oversight comes from the Electrical Safety Office (ESO) under Workplace Health and Safety Queensland, with Energy Queensland, Ergon Energy, and Energex overseeing grid connection requirements across the state.
These standards set clear rules for:
- Where a battery can and cannot be installed
- Minimum distances from windows, doors, and gas fittings
- Safety barriers between batteries and habitable rooms
The goal is simple — to make sure every installation is safe, durable, and fit for Queensland homes.
Where a Battery Must Not Be Installed
To reduce fire and impact risks, Queensland’s standards specify where a battery cannot be placed.
Batteries must NOT be installed in:
- Hazardous areas, such as gas cylinder or vent zones
- Escape routes like hallways, walkways, or under stairs
- Ceiling spaces or wall cavities, unless inside a compliant enclosure
- Habitable rooms, including bedrooms, living areas, and kitchens
- Wet or exposed areas, unless the unit is IP-rated and correctly mounted outdoors
For most Sunshine Coast homes, the garage or an exterior wall is the best and safest location.
What Counts as a Habitable Room?
Under the Queensland Building Code (aligned with the National Construction Code), a habitable room is any space used for daily living — such as bedrooms, living rooms, dining areas, or studies.
If your battery backs onto one of these rooms, it needs a non-combustible fire barrier or must be moved to another suitable location.
Rule of thumb: Never mount a battery directly on a wall shared with a habitable room unless a compliant fire barrier is installed.
Minimum Distances from Openings and Equipment
Here are the key minimum clearances set by AS/NZS 5139 and Queensland’s ESO:
| Area / Item | Minimum Clearance |
|---|---|
| Openable windows and vents | 600 mm horizontally, 900 mm below |
| Doors and exits (≤900 mm wide) | 600 mm minimum |
| Garage or yard doors | 1000 mm clearance for access |
| Electrical appliances | 600 mm horizontally, 900 mm above |
| Gas fittings / vents | 1000 mm radius, 1500 mm in vent direction |
Fire Barriers for Walls Backing Habitable Rooms
If the battery is installed on or near a wall adjoining a habitable room, Queensland regulations require a non-combustible fire barrier such as:
- Brick or concrete
- Fibre cement sheet
- Masonry block
- Ceramic or terracotta tile
The barrier must:
- Extend 600 mm beyond the battery on each side
- Extend 900 mm above the top
- Be sealed with no openings larger than 5 mm
Access, Egress, and Impact Protection
Every battery installation must remain clear of walkways and exits. We maintain at least 1 metre of open space for easy access and maintenance.
If the battery is installed in a garage, carport, or driveway, it must be protected from potential vehicle impact using bollards or another solid barrier.
Tip: Bollards aren’t about aesthetics — they prevent costly damage and keep your home safe.
Indoor vs Outdoor Installations
For Sunshine Coast conditions, outdoor or garage placement is generally preferred. Indoor installs are possible but must meet all fire and clearance requirements.
During your site assessment, our team will check:
- Nearby gas fittings or hot water systems
- Pathways and access zones
- Ventilation and airflow
- Future battery expansion space
That way, your system remains safe, scalable, and compliant for years to come.
Manufacturer Clearances Still Apply
AS/NZS 5139 sets the legal minimum for battery installation, but each manufacturer provides its own airflow and service clearance requirements.
For example, the Sungrow SBR Battery Series recommends:
- Left/right sides: ≥ 200 mm
- Above: ≥ 200 mm
- Below: ≥ 100 mm
- In front (service space): ≥ 300 mm
- Between stacked units: ≥ 150 mm
These clearances ensure safe operation, proper ventilation, and easy maintenance — and must always be followed in addition to AS/NZS 5139 and Queensland Electrical Safety Office guidelines.
Our Compliance Process
At SolarWide, we ensure every system meets or exceeds the following standards:
- Tested and verified to AS/NZS 3000
- Labelled, earthed, and protected per AS/NZS 5139 Sections 4–6
- Inverter and solar compliance to AS/NZS 4777.1 and AS/NZS 5033
- Grid connection approvals submitted to Energex or Ergon Energy
Every detail is handled by our accredited team — from installation planning to safety documentation.
