    Safety rules DANGER! “DANGER!” indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury. This signal word must be limited to the most extreme situations. This signal word is not used for hazards relating to property damage unless there is also a risk of personal injury appropriate to this level.

    How a photovoltaic system works The amount of solar energy radiated worldwide amounts to approx. General 1,540,000,000,000,000,000 kWh per year (1,540 peta kWh / year). This is 15,000 times more than the total electricity consumed. We would like to congratulate you on your decision to make active use of the world’s largest energy pool.

    Needless to say, it retains all its settings and stored data. The FRONIUS IG is designed for use with solar modules with a wide range of voltage Voltage transfor- input. This enables the widest possible variety of types of solar module to be used.

  • Page 17: Monitoring The Mains Network

    Insolation In addition to the functions implemented in the FRONIUS IG, the wide range of data communication elements enables a multitude of different data logging and display options. The add-on system components required for this purpose are easy to install (see operating instructions for FRONIUS IG DatCom).

    In order to distinguish between several identical add-on system components, each one of them must be assigned a unique number. Likewise, in order for each FRONIUS IG to be defined unambiguously in the LocalNet, they must also be assigned a separate number each.

  • Page 65: Class 1

    Service codes in service class 1 generally only arise momentarily, and are caused by the public mains network. The initial response of the FRONIUS IG in this case is to disconnect itself from the mains. The mains is subsequently checked for the stipulated monitoring period. If no further problem has been detected by the end of this period, then the FRONIUS IG will resume feeding power into the mains.

  • Page 66: Class 2

    Class 2 service codes are also related to the mains parameters. Therefore, some of the testing methods overlap with those for service class 1. The FRONIUS IG will react in exactly the same way as with class 1 service codes.
