Fronius ECO 27.0-3-S WLAN DC OVP Product Description

Eco 27.0 3 S WALAN DC OVP

Fronius Eco 27.0 3 S WALAN DC OVP
THE COMPACT PROJECT INVERTER FOR MAXIMUM YIELDS.

The 3 phase Fronius Eco in power categories 25.0 and 27.0 kW perfectly meets all the requirements of large scale installations. Thanks to its light weight and SnapINverter mounting system, this transformerless device can be installed quickly and easily either indoors or outdoors. This inverter series sets new standards with its IP 66 protection class. In addition, its integrated all pole string fuse holders and optional DC fuse mean that string collection boxes are no longer required.
SNAPINVERTER TECHNOLOGY The SnapINverter generation of inverters features a simple, standardised mounting system, making installation and maintenance easier than ever. A special feature in the design of the device is that the connection area is separate from the power stage set compartment, with both being installed separately. The remarkably light connection area and all its cabling is fitted to the wall first, followed by the power stage set. The innovative hinged system makes installation and servicing extremely user friendly. The inverter is simply placed in the wall bracket and then secured. This means that it is not necessary to remove the entire inverter for servicing, just the power stage set. All the cabling remains in place.
INTEGRATED DATA COMMUNICATION We are the first inverter manufacturer to offer a data communication package with fully integrated datalogging, WLAN, Ethernet, energy management, web server and a range of interfaces. The inverter is connected to the internet by network cable or WLAN without additional cabling and grants you the perfect overview of how the PV system is operating. Connection to third party components is provided by means of interfaces such as Modbus TCP SunSpec, Modbus RTU SunSpec or Fronius Solar API JSON . The open interfaces can also be operated in parallel to the Fronius Solar.web.
SMART GRID READY Fronius inverters are ready for the Smart Grid of tomorrow. The inverters are optimally equipped to meet the technical requirements of grids in the future. A series of smart functions, known as Advanced Grid Features, are built into the devices. They include a number of control functions for optimum feed in of reactive power and effective power. These functions are designed to enable stable grid operation even when the PV system density is very high and to prevent unwanted interruptions to feed in and associated yield losses if grid parameters exceed the thresholds. Fronius inverters therefore help to guarantee the yield of a PV system. Furthermore, where feed in limits are imposed, Fronius inverters can provide dynamic feed in control with self consumption taken into account. Just connect the meter and set the feed in limit!
DYNAMIC PEAK MANAGER The Dynamic Peak Manager is a new MPP tracking algorithm that dynamically adapts its behaviour when searching for the optimal operating point. Its special feature is that the Dynamic Peak Manager automatically checks the entire characteristic curve on a regular basis and finds the global Maximum Power Point GMPP , even in partial shade.
ZERO FEED IN Today, an increasing number of grid operators in various countries are stipulating a PV power feed in limit as a precondition before a system is connected to the grid. With dynamic power reduction, Fronius is offering a solution for optimum feed in management. The Inverter supplies the household consumers with energy first and then reduces the system Output to the maximum energy feed in permitted by the grid operator. With Fronius inverters, zero feed in is also a possibility thanks to this function, meaning that no PV power is fed into the grid. The relevant requirements of the grid operator can be fulfilled by simply enabling a Setting on the inverter's web interface.
ACTIVE COOLING Active cooling technology relies on 1 or more fans, which not only avoid hot spots, but also regulate the air circulation inside the inverter, thus keeping the temperature of the power electronics low. This has a positive effect on the service life of the devices, optimises yields and reduces costs. At Fronius, active cooling is supplied as standard in all devices.
