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.
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.
While the Doonan project was residential in scope, it required the high-level engineering precision typically reserved for critical infrastructure. By applying our core Industrial Power System Services we were able to design a robust, off-grid architecture that ensures the SLR1000 provides seamless power delivery regardless of grid instability.
Working with Solaron
