Fronius introduces the first string inverter to the project market

“The Fronius Eco is the ideal project inverter. It is easy to service, extremely cost-effective and offers the high quality associated with Fronius,” explains Martin Hackl, head of the Solar Energy Division at Fronius International GmbH.

The compact design ensures maximum average power density and maximum yields
Its lightweight design (weighing just 35.7 kg) and tried and tested SnapINverter mounting technology make for quick and easy installation. With the highest average power density in its power category, the Fronius Eco is sure to impress.

The new MPP tracking algorithm of the Dynamic Peak Manager also plays an important role in maximising yield. It automatically checks the characteristic curve at regular intervals, ensuring that the inverter finds the global maximum and constantly operates at the point of maximum output, even in partial shading.

Unique advantages for commercial projects
The efficiency level of 98.3 percent is unique in the project area. Another highlight is the ability to connect up to six strings directly to the inverter, meaning that the system operator no longer requires additional DC or combiner boxes. The integrated fuse holder provides all-pole fuse protection for all six strings, and optional overvoltage protection is available for the DC side.

Thanks to the exceptionally high IP 66 protection class, the device can be installed in unsheltered indoor and outdoor locations. The Fronius Eco even manages to deliver maximum yields under extreme climate conditions. Due to the SnapINverter technology², the lowest servicing costs can be expected. The optimised display navigation simplifies servicing, while the Setup wizard saves time and money.

Future-proofing is our priority
Smart Grid Ready is a keyword for future inverter applications. So is plug-in card technology, which enables the device to respond flexibly to future requirements. “The best example for this is our Fronius IG series. These devices came onto the market 20 years ago and can easily be made compatible for wireless applications today. That's what we call future-proof,” explains Martin Hackl. Optional plug-in cards, such as the Fronius Sensor Card, are easily integrated using the Plug&Play feature and the inverter is state-of-the-art once again.

In addition to Modbus TCP and RTU SunSpec, a Fronius Solar API (JSON) interface is available. The Fronius push service enables system data to be sent to any server. The online Fronius Solar.web platform is also available for comprehensive system monitoring and can be used at the same time as the open interfaces.

The Fronius Eco inverter is one of the Fronius highlights at this year's Intersolar Europe, which takes place in Munich (Germany) from 10-12 June. We look forward to seeing you in Hall B3, Stand B3.230.
