Off-Grid Systems

Wildwood Estate: 230kW Solar PV, 250kW/600kWh BESS & 176kVA Generators

Wildwood Estate is the holiday estate for a wealthy mining family, south east of Yallingup in Western Australia. Sunrise identified an off-grid stand-alone power system (SPS) solution as an opportunity to avoid the high costs associated with the required network connection upgrade.

Through consultation and analysis of the energy options available, Sunrise designed, supplied and installed a “small commercial solution”. The solution comprises of a 600kWh AlphaESS battery with a 250KW Sinexcel battery inverter, a 230kW solar PV array with 4x50kW GoodWe solar inverters and two 176kVA backup diesel generators.

The system was commissioned in September 2020 and has been running well since. The solar and battery can accommodate the maximum daily consumption without the use of diesel during reasonable weather conditions. In the first year of operation the system has provided more than 85% renewable content to the owners saving them electricity costs and creating a positive environmental impact.

Real time monitoring and control of the system is achieved through the energy management system (EMS). The below image shows an example of the EMS dashboard showing the generation and consumption data as well as the state of charge of the BESS.

Koobeja 1 : 40kWp Rooftop Solar PV array, 50kW/100kWh BESS & 50kVA Generators

In July 2021, we completed the installation of another SPS for the Wildwood owners at their Koobeja property in The Lakes, Western Australia. The solution comprises a 50kW Sinexcel hybrid inverter and 100kWh battery storage capacity using AlphaESS batteries and 40kWp of solar PV. The solar is mounted on a shed at the property and connected to the hybrid inverter that is housed in a custom-built plant room that was added to the back of the shed. A 50kVA diesel generator is also connected to the system and a second 50kVA diesel generator is available for backup or maintenance via a manual transfer switch.

Koobeja 2: 65kWp Ground Mount Solar PV array, 50kW/200kWh BESS & 88kVA Generators

In March-23, we commissioned a stand-alone power system (SPS) for a newly built home on the Koobeja estate. To maintain aesthetics, a custom plant room to house the battery and associated electrical equipment was designed and built. The 65kWp north facing ground mount solar array was installed, consisting of three rows with the plant room and diesel generator situated at the south end.

The client wanted high renewable content for this system, ideally as close to 100% as possible. They also wanted us to design the system so that it could support EV charging and make provisions so that the system can be expanded in the future. To help achieve this we created a load profile for the property which was then extrapolated into a 12-month synthetic load. Using this data, we modelled the solar generation and battery storage so that we could define the system requirements to achieve high renewable content. An 88kVA diesel generator was installed so that during winter when lower solar irradiance is expected the generator can support the house load and quickly charge the battery, reducing diesel run time and consumption.

Koobeja 3 – Shed: 34kWp Rooftop Solar PV array, 50kW/68kWh BESS & 50kVA Generator.

Another SPS at the Koobeja estate for the new farm shed was commissioned in April-23. Another custom plant room to house the battery and associated electrical equipment has been designed, built, and installed for this system.

Testimonials

Working with Sunrise and their partners for delivery of a 3MW Solar Farm at Boonanarring was a positive experience. They demonstrated not only a deep knowledge of renewable energy systems but were focussed on understanding our needs as a company and making sure they focussed on how these could best be served. Our satisfaction with the work done by Sunrise and their partners has led to an on-going relationship with Sunrise and they are our first point of call when seeking advice and solutions around renewable energy based projects.

Todd Colton ,

Chief Operating Officer

Sunrise Energy Group (Sunrise) and it’s partners (Avora Energy and Jarrah Solutions) were instrumental to the development of the Peel Industrial Renewable Energy Microgrid. They took on the lead roles of design, project management and construction of key components of this first-of-its-kind microgrid, notably with regards to the embedded generation and storage assets, the control and protection scheme and obtaining the approvals to operate and connection to the SWIS grid. Sunrise’s involvement demonstrated and highlighted their ability to navigate the complex landscape of regulations, network connections and operating licences in the WA market and was crucial to making the Peel Industrial Renewable Energy microgrid both a reality and ongoing success.

Rob Breden ,

General Manager

In delivering an off-grid renewable power system at our facility located in the South-West, Sunrise Energy Group and their partners proved to be a very capable, proactive and trustworthy supplier. The excellent performance of our system made it easy to select Sunrise as our partner of choice for delivery of similar systems at other properties and has also resulted in an ongoing relationship with Sunrise as we collaborate on other renewable energy based endeavours
