Off Grid Solar for a New Home in Mannum, South Australia.

Written by MyEnergy Engineering | Jan 28, 2026

Mannum is a well-known riverside town along the Murray River in South Australia, offering a mix of established homes, farming properties and growing rural developments, and is also a popular riverside holiday destination. While the town itself has grid access, new builds on larger rural allotments often sit too far from existing connection points. In these situations, off grid solar provides a practical and dependable solution from the outset, particularly where planning approvals rely on having an established power supply in place.

New Build Off Grid Solar Requirements

For this property, council regulations required a power source to be installed before approval could be granted for the future shed and home build. With no existing infrastructure on site, which meant no roof space available at this early stage, careful planning was required to determine the most suitable location for the system and solar panels. MyEnergy worked directly from the owners’ building plans to design an off grid solar system that could support early site works while delivering long-term value for the full residential build. The system was designed to meet the client’s needs today, with ample capacity to expand as future development plans progress. 

Scalable Off Grid Solar

The off grid solar power system was planned, built within a large vermin and weather-proof steel cabinet and thoroughly tested at MyEnergy HQ before being transported to Mannum for a seamless on-site installation. 

The off grid solar array consists of 16 JA Solar panels installed on a ground-mounted S-RACK system, with poles driven using a GAYK pile driving machine by our in-house team. Built to suit local conditions, including heat and dust, the off grid solar system features a Victron MultiPlus-II inverter, Victron SmartSolar charge controller and Victron Ekrano GX for monitoring. Paired with 24kWh of Pylontech battery storage, this off grid solar system delivers dependable power for early works while providing the capacity to scale as the property’s needs evolve.
