Darch 50 kWh Alpha Battery and 7.65 kW Solar Installation

Expanding an Existing Solar System with High-Capacity Storage and Backup Protection

This Darch home was recently upgraded with a 50 kWh Alpha battery system paired with a 5 kW inverter and 7.65 kW of new solar panels. The installation ties into the homeowner’s existing rooftop solar and includes blackout protection for uninterrupted power during outages.

Installed Components

• 50 kWh Alpha battery bank
• 5 kW hybrid inverter
• 7.65 kW rooftop solar array
• Integration with the home’s existing solar panels
• Multiple cabinet-style battery units positioned along the garage wall
• Rigid conduit linking all system components
• Blackout protection configured for automatic switchover
• Impact-rated bollards installed in front of each cabinet

Installation Layout and Method

The rooftop panels were arranged across several roof faces to maximise daily production and complement the homeowner’s existing solar array. This provides a strong combined output throughout the day.

Indoors, the Alpha battery units were mounted with even spacing to allow airflow and ensure straightforward access for future servicing. Conduit was routed cleanly across the wall to interconnect all equipment in a compliant and organised layout.

Safety bollards were anchored into the concrete floor to protect each battery cabinet from accidental vehicle impact. The system was configured to store excess solar production during the day and supply essential circuits automatically during grid outages.

System Benefits for the Household

• Significant overnight capacity from the 50 kWh battery bank
• Additional daytime production from the 7.65 kW solar upgrade
• Improved efficiency when paired with the existing rooftop system
• Automatic blackout protection during power interruptions
• Reduced grid reliance and lower peak-period imports
• Flexible setup ready for future expansion

Outcome

This Darch installation delivers a major increase in storage and solar capacity while integrating seamlessly with the home’s existing system. With a clean battery layout, protective bollards, and blackout protection, the setup provides long-term reliability, improved energy independence, and consistent performance year-round.
