Central Inverter Technology Integration in Utility-Scale Photovoltaic Plants
Metlen and Ingeteam have integrated central inverter equipment across six regional photovoltaic installations to deliver power conversion for 236 MVA of renewable capacity.

Ingeteam and Metlen have completed the deployment and energisation of 144 central power conversion units across six utility-scale photovoltaic installations in Australia. This cooperation addresses the grid integration and power conversion requirements of high-capacity solar assets feeding directly into regional transmission infrastructure.
Division of Engineering Responsibilities
The execution of these utility-scale projects relied on divided responsibilities matching each company's technical specialisation:
- Metlen: Acted as project developer and engineering, procurement, and construction (EPC) contractor, directing site engineering, civil works, balance-of-plant design, and overall grid interconnection.
- Ingeteam: Provided hardware manufacturing, system configuration, and commissioning support for the primary power conversion systems via its engineering subsidiary in North Wollongong.
Cooperation between the developer and hardware manufacturer was necessary to coordinate plant-level grid compliance with electrical conversion parameters across multiple geographical locations.
Technical Architecture and Power Conversion
The deployment comprises 144 central inverters distributed across six utility-scale sites, providing a total combined operational capacity of 236 MVA. Central inverters manage direct-current (DC) to alternating-current (AC) conversion from large arrays of photovoltaic strings before stepping up voltage for transmission.
In utility-scale energy infrastructure, central architectures streamline operations by consolidating power conditioning hardware at designated electrical stations. This approach optimizes thermal dissipation, simplifies scheduled maintenance, and standardises reactive power management to meet strict regional grid compatibility standards.
Multi-Site Deployment and Grid Integration
The systems were implemented across two Australian states, involving six discrete utility assets:

Multi-Site Deployment and Grid Integration
The systems were implemented across two Australian states, involving six discrete utility assets:
- Corowa Solar Farm (New South Wales)
- Junee Solar Farm (New South Wales)
- Wagga Solar Farm and Wagga Stage 2 (New South Wales)
- Wyalong Solar Farm (New South Wales)
- Kingaroy Solar Farm (Queensland)
Commissioning involved verifying dynamic inverter response, phase synchronisation, and voltage regulation against local network connection agreements. All six facilities are fully energised and dispatching electricity into the National Electricity Market (NEM).
Operational Impact
Standardising a single inverter platform across 236 MVA of generation capacity simplifies operational logistics for Metlen. Centralising maintenance protocols, spare parts inventories, and monitoring interfaces across six facilities lowers operational complexity. Furthermore, predictable power conversion and automated grid-fault ride-through capabilities maintain plant availability and stability across both the New South Wales and Queensland network nodes.
