50 kWh AC-Coupled Battery Upgrade in Mount Pleasant

A Major Boost to an Existing Solar Setup

This Mount Pleasant home received a significant energy upgrade with the installation of a 50 kWh AC-coupled battery system. The homeowner already had 6.6 kW of solar, and wanted deeper night-time storage, better self-consumption, and added protection during outages without replacing their existing inverter.

Equipment Installed

• 50 kWh AC-coupled battery bank
• Multiple cabinet-style battery units mounted along the garage wall
• Safety bollards positioned in front of each unit
• Rigid conduit linking all batteries to the control hardware
• Integration with the homeowner’s existing 6.6 kW solar array

How We Approached the Installation

The battery cabinets were spaced evenly across the garage wall to allow for airflow and future servicing. Conduit was routed cleanly across the brickwork, linking each battery to the main control unit while keeping the layout neat and compliant.

Each cabinet was fitted with an impact-rated bollard anchored into the concrete slab. This provides physical protection from vehicles and meets current standards for residential battery installations of this size.

The AC-coupled setup allows the battery system to capture excess solar production without modifying the existing rooftop system or inverter.

What This System Delivers for the Household

• Ample overnight storage from the 50 kWh battery bank
• Better use of daily solar generation
• Lower peak-time grid consumption
• Stable supply during outages
• Flexibility for future expansion of the solar array or additional loads

Final Outcome

With the addition of AC-coupled storage, the homeowner now has a robust, high-capacity energy system that works alongside their existing solar. The layout is tidy, compliant, and built for long-term performance while avoiding the need to alter the original 6.6 kW array.
