Description
About This Product
The Fronius 100kW TAURO ECO Three Phase Solar Inverter Direct Version is a commercial three-phase solar inverter designed for larger grid-connected PV systems. It is part of the Fronius Tauro ECO range and is intended for decentralised system layouts using the Direct version design.
This model provides 100kW AC nominal output and supports up to 150kWp of connected PV generator capacity. It uses a single MPP tracker with multiple DC string connection inputs, making it suited to straightforward commercial array layouts where high power handling and reliable operation are required.
The unit includes active cooling, a double-wall housing system, integrated DC disconnector, DC insulation monitoring, integrated residual current monitoring and integrated overvoltage protection. It is built for indoor or outdoor installation and is suitable for demanding Australian commercial solar environments when installed to the relevant standards.

Introducing Fronius Tauro
Who This Product Suits
The Fronius 100kW TAURO ECO Three Phase Solar Inverter Direct Version suits commercial and industrial solar installations that require a high-capacity three-phase inverter for grid-connected PV generation.
It is a good fit for warehouses, factories, large workshops, agricultural sites, schools, retail centres and other larger buildings with suitable three-phase supply and enough roof or ground-mount PV capacity to justify a 100kW inverter.
The Direct version is best suited to decentralised system designs, where inverters are positioned closer to the PV arrays rather than relying on a fully centralised inverter layout. It should be selected and installed by a qualified solar electrician who can confirm grid requirements, protection settings, string design and site compatibility.
Specifications Explained
The Fronius 100kW TAURO ECO Three Phase Solar Inverter Direct Version has a 100kW AC nominal output and a maximum AC apparent power of 100kVA. It is designed for three-phase grid connection and supports 50Hz and 60Hz operation, with Australian grid compliance including AS/NZS 4777.
On the DC side, the inverter supports up to 150kWp of PV generator capacity, with a DC input voltage range of 580V to 1000V and an MPP voltage range of 580V to 930V. It has one MPP tracker and multiple DC string inputs for commercial-scale array design.
Efficiency is rated up to 98.5%, helping reduce conversion losses in larger systems. Protection features include IP65 ingress protection, integrated DC disconnection, DC insulation measurement, residual current monitoring, string fusing and integrated Type 1 + 2 overvoltage protection depending on configuration.
Communication and control options include Ethernet, WLAN, Modbus TCP SunSpec, Fronius Solar API, RS485 Modbus RTU SunSpec, digital inputs and outputs, integrated data logging and web server functionality. This allows monitoring through Fronius Solar.web and integration with suitable commercial energy management or plant control systems.
Summary
The Fronius 100kW TAURO ECO Three Phase Solar Inverter Direct Version is a robust commercial inverter for larger three-phase PV systems. It combines 100kW AC output, high PV input capacity, strong monitoring options and practical protection features in a design suited to decentralised commercial installations.
For installers, the key appeal is its commercial power rating, integrated protection, Fronius monitoring platform support and flexible system integration. Correct string design, grid approval and installation by a licensed solar professional are essential for this type of inverter.
Further Information From The Manufacturer
