Mullaloo Solar Installation | Future-Proofed Energy with Sigenergy Hybrid Inverter
Project Overview – Mullaloo Solar & Battery-Ready System
This Mullaloo homeowner initially planned to install a standard non-hybrid inverter, but after careful consideration, they opted for a Sigenergy hybrid inverter at the last minute to ensure future battery compatibility. Thanks to Australis Solar’s flexible and customer-focused approach, we swiftly adjusted the installation plan to accommodate this upgrade.
The project also required:
✅ Main switch upgrade & RCD rewiring to meet Australian safety standards
✅ Removal of an old solar system to make way for a high-performance upgrade
✅ A phased installation to align with a planned roof restoration
Our expert team managed the process seamlessly, ensuring minimal disruption while optimising system performance.
