After one power outage too many, this energy-conscious customer decided it was time to go off-grid in style. The state-of-the-art BESS delivers all the power the customer needs for their residence.
To protect the homeowner from frequent grid instability and local blackouts, the installation relies on an autonomous routing layer to manage fluctuating rooftop solar generation. Integrating a highly advanced dc power management system ensures that energy distribution is 100% optimised between the PV arrays, the battery bank, and the home’s essential electrical circuits. This smart control network monitors individual cell health in real time, preventing deep discharge cycles and maximizing the lifespan of the hardware.
The Doonan SLR1000 represents a significant leap forward in home energy autonomy, utilizing a high-performance DC Power System architecture to ensure seamless energy storage and discharge. This setup allows homeowners to capture solar energy more efficiently, providing a reliable backup during grid outages while reducing reliance on rising electricity prices.
Many standard setups suffer from heavy conversion losses when repeatedly shifting power between alternating current and direct current formats. Opting for specialised dc power systems reduces these thermal losses significantly, leading to immediate energy savings over time. This streamlined architecture removes 100% of the standard conversion bottlenecks, delivering a 10% to 15% increase in total round-trip efficiency while providing a highly stable voltage output for sensitive home electronics.
To guarantee uninterrupted residential supply during extended low-sun periods, the internal power electronics incorporate a high degree of hardware redundancy. Utilising high-efficiency modular battery chargers allows the home storage unit to scale its charging capacity dynamically based on seasonal solar yield. This premium layout presents an excellent opportunity for growth in long-term site reliability, allowing individual rectifier modules to be safely hot-swapped without taking the entire domestic microgrid offline.
QUICK OVERVIEW
In the quiet leafy hills of Doonan in the foothills of the Noosa Shire, a residential property owner committed to a battery energy storage solution after losing power to his premises one too many times.
The site was already well developed sporting established gardens, pools, tennis courts and existing solar for the main house. The team at Solaron worked with the client to assess their power consumption needs and future expectations. A Battery Energy Storage System (BESS) was discussed and a design was agreed to using the Century Yuasa SLR1000 Advanced VRLA batteries.
Solaron completed the groundwork for the 30kW PV solar array including the civil works, land clearing and communication network. The BESS storage shed was designed and constructed by Solaron and the BESS power electronics were assembled with the support from Century Yuasa.
The success of this project can be attributed to the great relationship between the project owner and installer, Solaron and Century Yuasa who provided the battery experience needed to deliver this large quality residential system.
To maximise the lifecycle and safety of your lithium-ion investment, professional handling is essential. Our team brings decades of industrial experience to every DC Power System Installation, ensuring that your SLR1000 is commissioned according to strict Australian and New Zealand standards for thermal management and electrical safety.
