Page 13: Criteria For Selecting The Right String Fuses
String fuses are used in the Fronius Eco to provide additional protection for the solar mod- ules. The maximum short circuit current I , the maximum module return current I or the maxi- mum string fuse rating specified in the module data sheet of the respective solar module is crucial in affording the solar modules the correct fuse protection. -
Page 14: Data Communication And Solar Net
Data communication and Solar Net Fronius Solar Net Fronius Solar Net was developed to make system add-ons flexible to use in a variety of and data interface different applications. Fronius Solar Net is a data network that enables multiple inverters to be linked up using system add-ons. -

Page 16: Example
After cutting out because of overcurrent or undervoltage, the inverter attempts to restore the power supply in the Fronius Solar Net every 5 seconds while the fault is still present. Once the fault is rectified, power to the Fronius Solar Net will be restored within 5 seconds. - Page 17 This S0 meter can be positioned directly at the feed-in point or in the consumption branch. As one of the settings on the Fronius Datamanager website, a dynamic power re- duction can be set under the "EVU Editor" menu subitem (see Fronius Datamanager Op- erating Instructions under www.fronius.com/QR-link/4204260173DE)
