50 kWh AC-Coupled Battery Installation in Southern River

Supporting an Existing Solar System with Added Backup Protection

This Southern River home was recently upgraded with a 50 kWh AC-coupled Alpha ESS battery system designed to work alongside the household’s existing 6.6 kW solar array. The installation boosts stored energy capacity, strengthens backup capability on essential circuits, and helps the homeowner use more of their own solar power each day.

Installed Equipment

• 50 kWh AC-coupled Alpha ESS battery bank
• Multiple cabinet-style battery units installed side by side
• Integration with the homeowner’s existing 6.6 kW solar system
• Essential-circuit blackout protection
• Rigid conduit linking all units in a clean and structured layout

Installation Method and Layout

The battery cabinets were set out with consistent spacing and mounted securely along the alfresco wall. All interconnecting conduit was run neatly across the wall cavity to ensure a tidy, compliant finish that allows easy service access in the future.

As this system is AC-coupled, the batteries operate independently of the existing solar inverter. This means the homeowner can keep their current 6.6 kW solar installation unchanged while adding significant storage capacity.

Essential-circuit backup was configured to keep key areas powered if the grid goes down. This ensures refrigeration, lighting, and other priority loads remain operational during outages.

Benefits Delivered to the Homeowner

• Large 50 kWh storage capacity for extended overnight supply
• Improved use of daytime solar production
• Lower reliance on grid electricity
• Essential-circuit backup protection
• Retains compatibility with the existing solar inverter
• A clean and efficient installation suitable for long-term performance

Outcome

This Southern River project gives the homeowner a substantial upgrade to their energy independence. With a high-capacity battery bank, essential-circuit backup, and seamless integration with their existing 6.6 kW solar system, the setup is built for reliability, safety, and everyday savings.
