Gosford Pines: Delivering Full-Site Backup with AlphaESS G3-H50 and Parallel Back Up Technology

For agricultural businesses like Gosford Pines, maintaining power is critical to day-to-day operations. The client required a solution that not only reduced electricity costs but also ensured the site could continue operating during grid interruptions. The project needed to: maximise self-consumption of solar generation; reduce reliance on imported electricity; provide uninterrupted power during outages; and offer flexibility for future expansion. Rather than protecting only essential circuits, the requirement was to provide backup power for the entire site.

Products

• 3 Paralleled AlphaESS G3-H50 (150kW / 361.5kWh)
• AlphaESS Parallel Back Up Box

Services

• Engineering and technical support
• System integration guidance
• System commissioning

The completed installation combines 3 paralleled AlphaESS G3-H50 with the Parallel Back Up Box, creating a battery system capable of supporting the site's renewable energy system while also providing full-site backup. Unlike conventional backup systems that only supply selected circuits, the Parallel Back-Up Box enables the battery system to power the entire site during a grid outage. This provides an additional level of resilience for agricultural operations where maintaining power is essential. The modular G3-H50 platform also provides flexibility for future battery expansion as the site's energy requirements evolve.

• Increased self-consumption of on-site solar generation
• Reduced reliance on imported electricity
• Full site backup during grid outages
• Greater operational resilience
• Flexible battery platform ready for future expansion

• This project demonstrates how Immersa helps installer partners deliver more than just battery storage. By supporting Flex Eco Services with the latest AlphaESS technology and technical expertise, we enabled the delivery of a solution that combines renewable energy optimisation with complete site resilience.
• For agricultural and commercial businesses where uninterrupted power is essential, the combination of the G3-H50 and Parallel Back Up Box provides a compelling alternative to traditional backup systems while supporting long-term sustainability goals.
