Since 2016 the inverter standard mandates a whole raft of information be supplied to the end user. Any solar power system should come with a full 18 point documentation package, so under AS/NZS4777 you'll find clause 7.2 which includes:
- List of equipment
- Warranty information
- Equipment manual
- Equipment handbook
- Array frame/racking engineering certificate
- Shut down and isolation procedure
- System performance estimate, with numbers for monthly yield
- Maintenance requirements
- Earth fault alarm actions
- System connection diagram
- Site inspection checklist
- Testing/commissioning checklist
- Declaration of compliance
- Certificate of electrical safety (where applicable)
The rules have been updated at various times but for batteries the standard was updated in 2019.
As the popularity of batteries has exploded from 2025 onwards, it's worth noting systems are now much more complex. So you must receive a manual with at least 16 required items included, plus receipts and electrical safety certificate.
If your installer tries to leave you empty handed, remind them you need documentation as per the battery standard AS/NZS 5139. Documentation is not optional.
System manuals are mentioned as follows
Clause 4.4.1.2 details requirements for an integrated BESS (Battery Energy Storage System)
- Section 4 applies to a product that presents as an All-In-One system
- eg Tesla Powerwall 3, Sigenergy, GoodWe ESA
Clause 5.4.1.2 details requirements for a Pre-Assembled Battery System
- Section 5 applies to a product packaged and sold as a complete, tested system, but using a separate inverter and battery
- eg Fronius Gen24, Sungrow SH series, older model GoodWe & many others
Clause 6.4.1.2 details requirements for anything that isn't mentioned in section 4 or 5 above.
- Section 6 is "everything else" such as a more traditional remote area power system
- designed by a qualified off grid electrician
- built from separate parts
- often assembled on site
