- GRID PROTECTION BOARD
AS/NZS Compliant Grid Protection for Australian Networks
Purpose-built protection boards designed to meet DNSP requirements for every solar and renewable energy grid connection.
PRODUCT OVERVIEW
Manufactured to Australian Standards — Every Single Time
GreenBox Grid Protection Boards are purpose-built to meet DNSP requirements across all Australian states. Manufactured at our Clayton South facility to AS/NZS 3000 and AS4777 standards, each board is individually configured with the correct relay settings for your specific network area.
Every unit is factory-tested and supplied with full documentation including single-line diagrams, protection relay settings sheets, and commissioning test reports — giving you everything needed for a smooth grid connection approval.
Selectable relay options include ComAp and CHNT, both accepted by major DNSPs nationally. Available in single-phase 230V and three-phase 400V configurations with current ratings up to 400A.

APPLICATIONS
Where ATS Boxes Are Deployed
Commercial Solar (30kW+)
Meets DNSP protection requirements for large commercial rooftop installations requiring dedicated grid protection switchboards.
Industrial Rooftop
Robust IP65 enclosures and high fault-level ratings make these boards ideal for demanding industrial rooftop environments.
Ground-Mount Utility
Used at the inverter cluster level in ground-mount utility and agrivoltaic projects where centralised protection is required.
C&I Battery Storage
Integrated with battery energy storage systems to provide bi-directional protection and DNSP-compliant grid interface.
FAQ
Common Questions
Can’t find what you’re looking for? Our technical team is available to answer project-specific questions.
Which DNSPs are your grid protection boards approved for?
Our boards are configured to meet the requirements of major DNSPs including Ausgrid, Endeavour Energy, Essential Energy, Energex, Ergon, SA Power Networks, Western Power and TasNetworks. State-specific relay settings are applied at the factory.
What is the typical lead time for a standard grid protection board?
Standard configurations are typically available within 5–10 business days from order confirmation. Custom relay selections or non-standard enclosure sizes may extend this to 3–4 weeks. Contact us for project-specific scheduling.
What documentation is included with each board?
Every board ships with a full documentation package including the single-line diagram, protection relay settings sheet signed by our engineer, factory insulation and functional test report, DNSP compliance declaration, and a wiring schedule.
Are the boards factory tested before dispatch?
Yes. 100% of boards undergo functional relay testing, insulation resistance testing (1000V DC), and a complete visual and wiring inspection at our Clayton South facility. Test reports are included in the documentation package.
Can you configure boards to different state-specific requirements?
Absolutely. Relay settings, disconnect thresholds, and reconnect timers are configured at the factory to the specific DNSP requirements for your project’s network area. Simply specify the connection address and network when ordering.
What warranty do you provide?
GreenBox Grid Protection Boards carry a 2-year workmanship warranty from date of dispatch. Relay and component warranties are passed through from the relevant manufacturers (ComAp and CHNT both provide 2-year hardware warranties).
