50 kWh AC-Coupled Battery Addition in Harrisdale

Expanding an Existing Solar System with High-Capacity Storage

This Harrisdale property received a recent upgrade featuring a 50 kWh AC-coupled Alpha ESS battery system. The installation was designed to integrate smoothly with the homeowner’s existing solar PV system while adding blackout protection for essential circuits.

Equipment Installed

• 50 kWh AC-coupled Alpha ESS battery bank
• Multiple cabinet-style battery units installed in a compact outdoor layout
• Essential-circuit blackout protection
• Hardwired conduit connecting all battery modules and control components
• Full integration with the existing solar PV system

Installation Setup and Layout

The battery units were positioned along the side of the home, spaced neatly to allow for airflow, servicing, and safe operation. Conduit was routed cleanly across the brickwork to tie the units into the inverter and backup supply components.

As an AC-coupled configuration, the system was connected to the home’s existing solar installation without any modifications to the current inverter. This allowed the homeowner to upgrade their storage capacity while keeping their roof-top system unchanged.

Backup protection was configured to supply essential loads during a power outage, ensuring the home remains partially operational even when the grid goes down.

Homeowner Advantages

• Large 50 kWh storage capacity for extended overnight use
• Greater self-consumption of solar energy
• Reduced grid reliance during high-tariff periods
• Backup protection for essential household circuits
• Clean, organised installation designed for long-term reliability

Result

The Harrisdale installation provides a valuable storage upgrade for an existing solar system. With significant battery capacity, dependable blackout protection, and a tidy, space-efficient layout, the homeowner now benefits from improved energy independence and added resilience.
