Project Overview
The homeowner in Moorebank was ready to move toward total energy autonomy but faced a significant hurdle: space. Living in a townhouse-style property, there was virtually no compliant exterior wall space large enough to house a high-capacity battery system. They needed a technical team capable of thinking outside the box, literally.
What the client needed
- High-Capacity Storage: A large-scale battery (32kWh) to capture maximum solar energy.
- Compliance in Small Spaces: A solution that met strict Australian installation standards despite limited property footprints.
- System Modernization: Integration of their existing solar panels into a new, high-performance battery ecosystem.
Our objectives
- Create Installable Space: Design and build a structural solution to mount the battery where none previously existed.
- Complex Re-Engineering: Decommission the old inverter and re-cable existing PV arrays to work with the new SigEnergy controller.
- Long-Distance Integration: Manage a large cable run across the property without compromising aesthetic or electrical efficiency.
Provided Solutions
We recommended the SigEnergy SigenStor, a modular, “5-in-1” energy storage system. To solve the space crisis, we suggested building a solid concrete wall in a previously unused “dead space” on the property. This allowed for a fully compliant installation while keeping the footprint minimal.
Our technicians replaced the existing inverter with a 10kW 3-Phase Sigen Controller, effectively turning the old solar system into a modern, DC-coupled powerhouse. This required extensive re-cabling of the existing arrays and a complex cable run to connect the rooftop generation to the new battery location.
Final Outcome
Despite the logistical challenges, the team delivered a flawless installation. The customer now has a massive 32kWh of storage, allowing them to run their townhouse almost entirely on self-generated power. The custom concrete wall not only ensured compliance but also saved the client significantly on alternative installation costs. The result is a high-performing, future-proof system that has left the client extremely satisfied.
