Example of a compliant sign for SB & Labelling 16.
Under this standard, inverters may operate in multiple modes, including supplying power independently or alongside the grid. In these situations, operating an isolation device may not fully de-energise all conductors, particularly neutral and earth circuits.
Considering additional switchboards and system components
Battery installations may introduce additional equipment such as gateways or backup devices. Where these include switching or protection components, they form part of the electrical distribution path. In these configurations, they operate like distribution switchboards.
Applying the required warning signage at these locations supports a consistent understanding of system operation and isolation outcomes.
Supporting safe isolation through signage
To support safe interaction, the standard requires warning signage to be installed at:
- the main switchboard
- any distribution switchboards or gateway between the main switchboard and the inverter connection point.
The signage should communicate:
- an alternative supply is present
- neutral and earth conductors may remain energised
- shutdown procedures should be followed before work is undertaken.
Further learning and support
Solar Accreditation Australia’s Solar Battery Labelling Course (COM004), developed in collaboration with us, includes:
- battery labelling requirements
- compliant vs non-compliant examples
- common non-compliances observed in inspections.
Daily installation limits
The daily installation limits outlined in SAA’s technical requirements still apply.
The installation date is the day you’re on-site to test and commission the system. This will be the date of test on the certificate of electrical safety (CES). The installation date can’t change.
When taking on-site verification photos of the installation, remember:
- your photos must represent the total time on site – make sure to take your final photo when testing the system
- photos must be taken on approved SPV apps or on your phone with location services on and original metadata (don’t use unapproved apps)
- if your SPV app isn’t working, take back-up photos on your phone instead – they must include geolocation and time stamping
- DO NOT return to site at a later date to take selfies or change the installation date on your CES.
Critical labelling
You must take photos of critical labelling on all solar battery installations and provide them as part of your compliance paperwork.
Read our solar battery photo guide to see what photos you need to take and where to find more information about labelling requirements. You can also refer to our solar battery inspection checklist to see the labels that are assessed as part of our inspection program.
If your claim is failed, you can return to site to rectify the labelling issue.
