Product details
TAURO
TAURO by Fronius is a series of three-phase photovoltaic inverters with a rated AC power of 50–100 kW, depending on the model. The version with direct string connection provides flexibility in system design and optimizes the cost of its additional components. Active cooling with a double-wall system enables maximum performance even at a temperature of 50°C.
Key advantages of TAURO
- Maximum efficiency 98.5–98.6% and European weighted efficiency of 98.1–98.2%, depending on the model.
- Direct connection of PV strings via Stäubli Multi-Contact MC4 connectors and 1–3 maximum power point trackers, depending on the model.
- Indoor and outdoor installation: IP65 protection rating and suitability for exposure to direct sunlight.
- Replaceable power modules and active cooling with a double-wall system.
- Integrated protection: DC disconnect switch, reverse polarity protection, DC insulation measurement and type 1+2 DC/AC surge protection.
- Communication and energy management: Wi-Fi, two Ethernet ports, an integrated data logger and web server, and digital inputs and outputs for energy management and load control.
Who is this a good choice for?
TAURO is an option for photovoltaic system owners who need a three-phase inverter with a power output of 50–100 kW and direct string connection. Users planning outdoor installation can benefit from the IP65 enclosure and approval for sun exposure, while those managing energy in the system can use the communication interfaces and inputs and outputs to control loads.
