Tucked away in the rugged countryside of South Australia’s Fleurieu Peninsula, McHarg Creek is a serene rural area. It is known for its rolling hills and bushland. With no access to mains power and limited infrastructure nearby, homes in this region rely heavily on well-designed off grid solar systems. For one remote homeowner in McHarg Creek, it was time for a practical and future-ready upgrade.
Growing Energy Needs
The house had an existing off-grid setup. However, over time, the household's energy use began to exceed the system’s capacity. Rather than replacing the entire system, the owners chose a more sustainable approach. They decided to build upon what was already in place. This included adding more solar generation, expanding battery storage, and upgrading inverter capabilities to enhance performance and reliability.
A Tailored Off Grid Solar System Expansion
To meet everyday demands of off-grid living, MyEnergy designed a tailored system upgrade. This upgrade integrated seamlessly with the existing setup. One of the key features was the installation of 6.16kW of JA Solar panels on the shed roof, mounted using a Clenergy roof mounting system.
The solar array connects to a Victron MultiPlus-II inverter (5kVA). This is supported by a Victron SmartSolar charge controller and monitored via a Victron Cerbo GX. Power is stored in three Pylontech lithium batteries, which have a total capacity of 10.65kWh.

System Overview
Solar: 6.16kW JA Solar Panels
Inverter: 5kVA Victron MultiPlus-II Inverter 48/5000/70-50 230V
Storage: 10.65kWh Pylontech Lithium Batteries
