Available in power classes from 50 to 100 kW, the three-phase Fronius Tauro promises maximum performance, even in the most demanding conditions. Its intelligent hardware design not only helps to optimize system balance costs but also offers unprecedented flexibility in system design. With the Fronius Tauro inverter, both centralized (P version) and decentralized (D version) system designs can be implemented. In addition, one of the simplest installations and some of the fastest servicing on the market guarantee maximum safety.
Some advantages of the Tauro inverter:
There are many versions of the Fronius Tauro range, but how do we know which one we need? The Fronius Configurator will help you.
Using the configurator is very simple and quick. The system asks you 6 questions and you can choose from the answers provided.
The first question is the design of the system. For a centralized design, not short AC cabling but long DC cabling is required, and vice versa for a decentralized design. For large power plants (>1.2-1.6 MW) or if the transformer is far away, the centralized version is more practical, but in this case more strings have to be routed to the inverter in extra DC collector boxes. Also, the centralized version has the usual MC4 DC connectors, and the decentralized version has DC gland boxes that can accept 90 mm2 cables.

The second question asks you to choose the power rating (50, 99, or 100 kW) and the number of MPPTs of the inverter. The ECO inverters have 1 MPPT and a narrower voltage range (580-930 V), whereas the regular inverter has 3 MPPTs and a wider voltage range (400-870 V). ECO inverters are more useful for large power plants, where there is likely to be no different orientation and tilt. And the standard design can overcome these problems. The 99 kW inverter is needed to comply with the limits. In many calls for tender, it is stated, e.g. “power plant below 500 kW”. In such cases, 4×100 kW and 1×99 kW are the appropriate choices

Thirdly, we can select the fuses: a 15 A fuse is recommended up to 10 A module current, and a 20 A fuse up to 14.5 A module current. For modules with higher currents, such as the Canadian Solar HiKu7, we should choose the P (precombined) inverter, which has a significantly higher input current. Fuses are only required for the D (decentralized) versions, for P (precombined) systems they must be placed outside the inverter in a separate socket.

The next step is to decide on the SPDs. Do we need AC and DC T1+T2, or is plain AC and DC T2 enough? These SPDs are standard, so we can replace them with any other standard device in the inverter later.

SPD Type 2 (4,240,332)
The next option is to design the AC cabling. We have three options:
AC Daisy Chaining (4,240,330)
Single-Core (4,240,329)
Multi-Core (4,240,328)
Finally, we need to decide whether we want an AC disconnect switch or not.

If everything is selected correctly, the system will tell you which inverter you need and what features it has. We can add this to our configuration, or add an inverter with other parameters if required.
