Episode 7: GoodWe Powering a Supermarket

On This Page

In episode 7 of Energy Matters, we explore how IGA Morphett Vale has embraced energy independence. By integrating GoodWe’s advanced inverter and battery technology, the supermarket is reducing its energy bills and ensuring uninterrupted operations.

Behind the scenes: IGA Morphett Vale's energy transformation

Owners Nik and Daniel Papatolis, in collaboration with Solaring, implemented a renewable energy solution tailored to their store’s needs. The system comprises a 60kW solar array, a GoodWe GW29.9k-ET Hybrid Inverter, and 102.4kWh of Lynx F G2 battery storage. This setup enables the store to generate and store substantial energy, reducing reliance on the grid and providing backup power during outages.​

Dean Williamson from GoodWe highlighted the system’s benefits, noting that the inverter’s oversizing capability allows for up to 200% DC input, maximizing energy production. The Lynx F G2 batteries ensure that critical operations, such as refrigeration and payment systems, remain functional during power disruptions.​

Since the installation, IGA Morphett Vale has experienced a 50% reduction in monthly power costs. Plans are underway to expand the system further, enhancing the store’s energy autonomy.

GoodWe EHB Hybrid inverter

Why it’s a smart choice

The ET Series isn’t just about pushing power, it’s about flexibility and future-proofing. With up to 200% oversizing, businesses like IGA Morphett Vale can install more panels than typical systems allow, maximising solar harvest without overloading the inverter. The ability to seamlessly switch between grid, solar, and battery power ensures uninterrupted operations, a must-have for businesses relying on constant power.

GoodWe Lynx F G2 Battery

The Lynx F G2 is a high-voltage, modular battery system suitable for both residential and commercial use. Key features include:​

  • Capacity per Module: 3.2kWh
  • Modules per Tower: 2 to 9 (6.4kWh to 28.8kWh)
  • Parallel Connection: Up to 8 towers (max. 230kWh)
  • Battery Type: Lithium Iron Phosphate (LFP)
  • Design: Stackable, self-detecting modules for easy installation and maintenance
  • Monitoring: Remote monitoring via a single app​

Why it’s a great fit

GoodWe’s Lynx F G2 battery is designed to scale with your business. Its modular, stackable design allows for easy expansion as energy needs grow, no complicated rewiring or downtime. Built with LFP chemistry, it delivers high safety standards, longer lifecycles, and consistent performance. For IGA, that means less waste, more savings, and power security no matter what’s happening on the grid.

The combination of the GW29.9k-ET inverter and Lynx F G2 battery provides IGA Morphett Vale with a robust energy solution, ensuring operational continuity and significant cost savings.
