Inverter Solutions for Utility-Scaled Photovoltaic Power Plants

This paper presents an overview of the key technologies and solutions adopted in utility-scaled photovoltaic inverters for large scale photovoltaic plants. The overview starts by presenting the circuit topology and cooling system. Subsequently, it focuses on the on-site integration and deployment of the system and finally on the introduction of a modular-type solution that enables photovoltaic and energy storage in the same low voltage bus.
