This table is provided for indicative purposes only. Installers should refer to the applicable DNSP requirements, connection processes and technical standards, and exercise their own professional judgement when determining system suitability and compliance.
The table reflects typical auto-approved system configurations applicable to connection applications submitted on or after 1 July 2026 and does not necessarily represent the maximum allowable system size. Larger battery systems can be assessed through a negotiated connection application, subject to DNSP requirements. Approval timeframes vary by DNSP and may range from a few business days to several weeks.
Additional battery configurations with lower AC output ratings are expected to become available later this year, providing greater flexibility in meeting DNSP connection requirements and auto-approval thresholds.
