54kWh Sigenergy Battery & 30kW Inverter Installation In Ivanhoe East
A large solar system can generate plenty of electricity during the day, but without adequate battery storage, much of that energy may be exported instead of used after sunset. At Albert’s Ivanhoe East home, the key challenge began after 4pm, when solar generation dropped while household electricity demand continued. His existing Schneider solar inverter was already supporting the property’s PV system, but there was no substantial storage to retain excess daytime generation.
Green Electric Solutions addressed this gap by installing a 54.24kWh Sigenergy battery system with 54kWh usable capacit and a 30kW three-phase inverter, adding high-capacity energy storage to the existing solar setup.
Why a 54kWh Battery Was Added to This Existing Solar System in Ivanhoe East, Melbourne
Unlike a typical residential battery project, this Ivanhoe East property already had an established solar PV system and required substantial energy storage. The installation added 54.24kWh of nominal battery capacity, with 54kWh usable, providing significantly greater energy-shifting capability than a standard home battery.
The existing solar system could generate surplus electricity during the day, but without adequate storage, much of that energy was exported to the grid before being purchased back at higher retail rates during the evening. The battery provides a way to retain more solar energy for later use.

How a 54kWh Battery System Was Installed Safely and Compliantly by Green Electric Solutions
The installation includes a new switchboard with dedicated circuit breakers, AC isolators and clear safety labelling for shutdown and earthing procedures. The battery inverter features a digital display, ventilation fans and neatly routed, colour-coded cabling through weatherproof glands. An outdoor enclosure provides additional isolation points, while the utility meter is secured with sealed, tamper-evident tags.
Two external emergency shutdown buttons allow rapid system isolation when required. Overall, the installation demonstrates careful switchboard segregation, accessible isolation points, clear labelling and organised electrical work designed to support safe operation and maintenance.
How 174 Battery STCs Cut the Project Cost By $6,786
The project received a substantial upfront reduction through 174 Battery STCs, with the homeowner assigning certificate creation rights to Green Electric Solutions. Based on the supplied project figures, the STCs provided a $6,786 reduction. This incentive significantly reduced the homeowner’s upfront investment. However, Battery STC values and eligibility can vary by installation, certificate rates, and applicable requirements, so the final rebate should always be confirmed for the specific project and installation date.
| Cost Component | Amount |
|---|---|
| Subtotal incl. GST | $32,116.00 |
| 174 Battery STCs × $39 | −$6,786.00 |
| Total incl. GST | $25,330.00 |
