50 kWh AC Coupled Battery System with Existing Solar in Dalkeith

Reliable Backup Supply and Increased Storage Capacity

This Dalkeith home received a major energy upgrade designed to maximise the performance of its existing 6.6 kW solar system. The installation adds 50 kWh of AC coupled battery storage along with blackout protection on essential circuits, giving the property far greater resilience and control over how solar energy is used throughout the day and night.

What Was Installed

• 50 kWh Alpha ESS battery system
• AC coupled battery inverter
• Integration with the customer’s existing 6.6 kW rooftop solar
• Essential-circuit blackout protection
• Clean, wall-mounted installation with protective bollards

Installation Notes and System Layout

The battery units were positioned neatly along the internal garage wall, spaced to ensure proper airflow and ease of future servicing. Conduits were run cleanly across the wall and ceiling to maintain a tidy setup that meets current safety and compliance standards.

The existing solar system was left in place and tied into the new AC coupled solution, allowing the home to store surplus generation without changing the roof layout. The blackout protection was wired to the chosen essential circuits, ensuring key areas of the home continue running during grid interruptions.

Protective bollards were installed in front of the battery units to prevent accidental impact inside the garage, offering an extra layer of safety and longevity.

How the System Benefits the Household

• Significantly increased storage capacity for higher solar self-consumption
• Ability to store surplus energy from the existing 6.6 kW solar array
• Blackout protection to keep essential areas powered during outages
• Reduced grid reliance and improved control over energy usage
• A clean, future-ready installation with room for expansion if required

Final Result

This Dalkeith upgrade transforms an existing solar system into a high-capacity, blackout-ready energy solution. With 50 kWh of storage and a streamlined installation layout, the homeowners now enjoy greater reliability, improved energy independence, and far better use of the solar power generated on-site.
