Case Study: A 42kWh FoxESS Battery Upgrade for a Gosnells Home

Quick Summary: Each house had different energy use and a different installation story. This installation focused on increasing the efficiency of the existing 6.6kW panels by adding a compatible battery system, which also provided high-capacity storage rather than replacing the existing panels. The family in Gosnells connected with Solar 365 via Meta, and this relationship of belief and faith proved to be a great investment for the family without any compromise.
The 42kWh battery system with a 10kW inverter was the ideal recommendation for the family and the customer's budget-friendly needs. The system allowed the customer to store his excess energy, which was utilised at night.
The Customer’s Objective
The homeowner's main goal was to maximize his solar investment by adding a battery to store excess electricity for use at night.
The generation from his existing panels exceeded his usage, and the excess was transferred to the grid. He wanted to reduce his electricity bill and increase his storage capacity, thereby achieving energy independence at minimal expense.
The Challenge
The existing 6.6kW panels were sufficient for the customer's electricity usage, but the main issue was the customer's still-high electricity bill. The reason was that most customers used it at night. The excess generation from the panels was fed to the grid because there was no storage.
The issue here was integrating a high-capacity battery into the current solar panel system while maintaining full compatibility, optimal performance, and long-term efficiency.
Our Solution

After collecting the necessary information and completing an inspection of the existing 6.6kW panels' performance and compatibility, Solar 365 recommended the 42kWh battery to him, which gave him complete independence with his system. The battery system was a little larger than he needed, but for many homeowners, installing a battery was a one-time investment. They could claim rebates only once per property, and this system improved performance and self-consumption, providing both long-term and immediate solutions. We have helped over 10 properties in Gosnells benefit from solar power through professional installations.
Installation Procedure
After the site assessment was completed, the installation procedure was carefully planned to ensure the entire process integrated seamlessly with the existing solar system.
The skilled installers carried out the installation of the10kW FoxESS Hybrid Inverter and the 42kWh FoxESS Battery to the highest Australian standards.
After the equipment was installed, thorough testing and commissioning were carried out to ensure that the inverter, battery, and existing solar panels would work together effectively. After testing was completed, the homeowner received a full system handover, including tips for monitoring system performance.
Conclusion
This led to the installation of an energy storage system that worked in tandem with the existing solar system.
