Project Overview
In Narellan Vale, we assisted a homeowner who already had a strong 13.2kW solar system in place but wanted to take the next step toward greater energy independence.
They needed a battery solution that could store excess solar energy and provide long-term savings, without replacing their existing setup.
This project involved adding battery storage to an established system, which required careful engineering and precise installation.
What the client needed
- Battery storage to maximise solar self-consumption
- An AC-coupled upgrade compatible with their existing solar system
- A clean and protected installation built to last
- Long-term savings through reduced grid reliance
Our objectives
For this Narellan Vale battery-only installation, our objectives were to:
- Seamlessly integrate a high-capacity battery with an existing 13.2kW solar system
- Deliver an AC-coupled solution without disruption to current performance
- Complete a complex cable run safely and professionally
- Ensure the battery system was sheltered and ready for decades of use
Provided Solutions
We installed a premium 25kWh Hinen battery storage system, designed to work as an AC-coupled add-on.
The solution included:
- A Hinen H5000 inverter for efficient energy conversion
- Hinen B5000 battery modules delivering large-scale storage
- An extensive cable run to connect the battery system from the opposite side of the property to the main switchboard
Despite the distance and complexity, our team ensured the installation remained neat, safe, and fully compliant.
We also positioned the battery in a well-sheltered location to protect it from the elements and support long-lasting performance.
Final Outcome
The homeowner now has a powerful battery upgrade that enhances their existing solar investment.
Key outcomes include:
- 25kWh of storage capacity ready to capture unused solar energy
- Reduced reliance on the grid, especially during evening hours
- A professionally engineered solution despite the challenging cable run
- A sheltered battery system built for durability and long-term savings
This upgrade sets the client up for years of stronger energy control and lower electricity costs.
