50 kWh AC-Coupled Battery Installation in Dianella

Enhancing a Standard Solar System with Large-Capacity Storage

This Dianella property was upgraded with a 50 kWh AC-coupled battery system to work alongside the homeowner’s existing 6.6 kW solar array. The goal was to increase stored energy for night-time use, reduce grid reliance, and provide a more stable supply during outages.

Installed Components

• 50 kWh AC-coupled battery bank
• Multiple cabinet-style battery units positioned along the wall
• Impact-rated bollards installed in front of each unit
• Rigid conduit connecting all battery cabinets to the control equipment
• Integration with the existing 6.6 kW solar system

Installation Layout and Method

The battery cabinets were mounted with even spacing, allowing airflow and ensuring clear access for any future servicing. Conduit was routed neatly across the wall to link the system together in a compliant and organised layout.

Each unit was fitted with a front-mounted safety bollard anchored into the concrete. This protects the battery bank from accidental impact and complies with current installation requirements for high-capacity residential batteries.

Because the system is AC-coupled, it operates independently of the existing inverter, allowing the homeowner to retain their original 6.6 kW solar installation without alteration.

System Benefits for the Household

• Substantial overnight supply from the 50 kWh battery bank
• Increased self-consumption of the existing solar generation
• Reduced grid imports during higher tariff periods
• Added stability during outages
• Flexibility to expand solar or add future loads

Outcome

The Dianella installation provides a significant storage upgrade that complements the existing rooftop system. With neat cabinet placement, clean conduit runs, and protective bollards, the setup is built for long-term performance and reliability while giving the homeowner far greater control over their energy usage.
