Solar batteries are a popular upgrade for Australian homes and businesses. In many cases, a battery can be installed using a “standard” setup. This means the site meets typical battery installation standards with minimal additional work. However, not all properties fall into this category.
When a system is considered a non-standard battery installation, understanding why is essential to controlling costs, maintaining safety, and ensuring it performs as intended. Some common triggers include backup power configurations, switchboard upgrades, and specific solar battery installation regulations that must be met before installation can proceed.
In this article, we’ll discuss what makes a battery installation “non-standard” and what it means in practice.
Common Triggers for a Non-Standard Battery Installation
A solar battery storage installation is considered non-standard when it requires additional components, labour, or compliance measures that go beyond a straightforward setup. These situations often arise due to site-specific electrical layouts, building structures, or customer requirements.
Non-standard installations are not unusual. Many residential installation projects and commercial solar battery installation sites encounter one or more of the scenarios below.
For reference, a standard VoltX Energy installation carries a $100 installation fee with most typical variations included. That standard fee specifically excludes major electrical works, long cable runs, blackout (backup) protection setup, and travel outside standard service areas—which are exactly the triggers described below. The figures that follow are indicative industry ranges to help you budget; your exact costs are confirmed as an itemised quote after a site assessment.
Backup Power Configuration Requirements
Standard battery systems are often installed solely for energy storage and self-consumption. Battery backup installation is typically classified as non-standard, being more complex. Standard backup protection (up to 2 circuits) is $500 with a manual changeover switch, or $600 with a 40A auto-change contactor that switches from grid to battery automatically during an outage. Each additional backup circuit beyond the first two is $100. If your existing circuit breakers are MCBs without a test button, they’ll need upgrading to RCBOs to meet AS/NZS 3000, at $80 (single-phase).
Three-Phase or Advanced Power Monitoring Needs
Homes and businesses with three-phase power systems require additional configuration. A three-phase solar battery installation needs specialised smart metres and multiple CT clamps to correctly monitor grid import/export, solar production, and household consumption.
A standard three-phase smart meter is $450, while the premium meter with 6 CTs—which also monitors production from an existing solar system—is $550. This complexity increases installation time and requires precise commissioning to ensure accurate energy management.
Switchboard and Electrical Compliance Upgrades
Older properties often have undersized or outdated switchboards. To meet modern home battery installation requirements, AS/NZS 3000 (the wiring rules) and AS/NZS 5139 (the battery-specific standard), upgrades may be necessary.
Switchboard modifications can include replacing boards, adding safety switches, or reorganising circuits. This can turn a simple job into a more complex installation. A switchboard upgrade is priced individually (POA). Where extra capacity is needed, an additional 12-pole sub-board is $450 indoors or $650 outdoors.
Long Cable Runs or Remote Installation Locations
The distance between the battery, inverter, and main switchboard matters. A standard installation generally covers a cable run of up to 5 metres; beyond that, long cable runs increase labour, material costs, and the risk of voltage drop.
A run over 5 m but within 10 m (no backup) is $150, and runs over 10 m but within 25 m are POA. When batteries are placed far from the main electrical system, more conduits and heavier cables are needed, which also takes extra time to install.
Removal or Modification of Existing Solar Equipment
Some sites already have older solar systems that are incompatible with new battery technology. This may involve removing old inverters, reconfiguring panel strings, or modifying existing wiring layouts. Removing an old inverter is $150, and removing old solar panels is $35 each.
Any home battery installation in Australia that requires reworking existing equipment typically falls under non-standard.
Fire Safety and Compliance Requirements
Fire safety is a key part of solar battery installation requirements, and clearances and fire separation are governed by AS/NZS 5139. When batteries are installed indoors, such as in a garage or utility room, you may need to take additional measures.
These can include fire-rated backing boards or smoke alarms, especially if the battery is mounted on non-concrete or non-brick surfaces. A fireproof board (2400 mm x 2440 mm coverage) for wooden or other non-masonry walls is $300, and the two fire alarms required for an indoor battery installation are $350 for supply and installation.
Questions like ‘Can solar batteries be installed in a garage?’ or ‘Can solar batteries be installed outside?’ depend heavily on compliance requirements and site conditions.
Physical Protection for Battery Location
If a battery is installed in a high-risk area, like near a driveway or outdoors, it often needs protection. Bollards, required when the battery sits in a driveway or car-park garage, are $150. A UV-protected canopy for a battery installed in an area without a shed—protecting it from overheating—is $400.
Property Structure and Installation Complexity
Certain building designs naturally increase installation complexity. Double-storey homes, terracotta tile roofs, and properties with multiple roof splits require more labour and planning.
A double-storey surcharge for roof solar panel installation is $200, each extra roof split beyond the first two panel strings is $150, and terracotta tile roofs carry an additional labour surcharge (POA).
Location and Travel Distance
While the installation itself may be straightforward, distance alone can make the job non-standard. Regional and remote properties may incur additional travel time and logistics costs. A single trip of 50–150 km is $250 (Travel Fee Level 1), and a single trip over 150 km is $500 (Travel Fee Level 2).
Custom or Unforeseen Site Conditions
Some properties present unique challenges that cannot be identified until a detailed site assessment is completed. Unusual wiring layouts, structural limits, or custom electrical designs often require tailored solutions. These are typically priced individually (POA).
