Future-Proof Island Living with Reliable Power
A residential property on Facing Island, located off Gladstone Harbour, Queensland, was originally used as a weekend retreat, with long-term plans to transition into a permanent residence.
Given the remote island location and limited access to grid services, the client required a reliable, scalable energy system that could support full-time living both now and into the future.
DPA worked closely with RJ Warren Solar & Electrical to supply a robust off-grid solution designed for reliability, performance and long-term flexibility.
The Requirements
The primary requirement was to future-proof the PV and battery storage system to accommodate the client’s plan to live permanently on the island.
This meant:
- Reliable, continuous power supply
- A system capable of expansion as energy needs increase
- Proven components suitable for off-grid and remote applications
- Clear system monitoring and control for long-term confidence
The Challenge
The project site presented several logistical challenges. Facing Island is only accessible by boat, with a limited local ferry service. Transporting equipment to site required careful planning and flexibility to avoid delays and minimise disruption to the installation timeline.
How It Was Delivered
Where possible, the RJ Warren team utilised the local ferry service. When ferry access was unavailable, they relied on their own 6-metre vessel to transport components to the island, enabling after-hours access and ensuring the project stayed on track.
This approach allowed the team to deliver and install the system with minimal disruption, despite the site’s remote location.
The System Solution
The final solution combines proven components designed for off-grid reliability, system visibility and future expansion.
Key system components include:
- Victron Multiplus 48/10000
- Victron Smart Solar MPPT RS 450/200
- GX Touch 50
- GX Touch 50 Wall Mount
- Cerbo GX MK2
- SmartShunt 500A / 50mV IP21
- PowerPlus Energy 10x Battery Cabinet IP21
- PowerPlus Energy ECO 51.2VDC 4.7kWh LFP Batteries (ECO4847P)
- 400A 750VDC 3-Pole MCCB
- 250A 500VDC 2-Pole MCCB
- MCCB Terminal Shield Suits (various ratings)
Together, these components provide a reliable, scalable and serviceable off-grid energy system, suitable for long-term island living.
The Outcome
The completed system delivers dependable power with the flexibility to grow as the client’s energy needs evolve.
Through close collaboration between DPA and RJ Warren Solar & Electrical, the project demonstrates how the right planning, products and experience can overcome logistical challenges and deliver reliable energy solutions — even in remote locations.
