    All ABB string inverters marketed in Europe are equipped with a device for protection against ground faults in accordance with the safety stand- ard set in Germany by Standard VDE V 0126-1-1:2006-02 (please refer to section 4.7 of the Standard).
  • Page 44 B ground fault interrupter. In accordance with article 712.413.1.1.1.2 of Section 712 of IEC Standard 64-8/7, we hereby declare that, because of their construction, ABB inverters do not inject ground fault direct currents. The use of an AC type circuit breaker with differential thermal magnetic protection with trip- ping current of 300 mA is advisable so as to prevent false tripping, due to the normal capaci- tive leakage current of photovoltaic modules.

  • Page 45: Independent Or Parallel Input Channels Configuration

    5 - Installation ndependent or parallel input channels configuration All the inverter models are equipped with two input channels (thus bene- fiting from two trackers for MPPT maximum power point tracking) which work independently of one another, which can be paralleled by levera- ging a single MPPT.

  • Page 47: Independent Channel Configuration (Default Configuration)

    5 - Installation ndependent channel configuration (default configuration) This configuration involves the use of the two input channels (MPPT) in independent mode. This means that the jumpers between the two channels (positive and negative) of the DC input terminal block must not be installed and the switch located on the main board must be set to “IND”.

  • Page 48: Input Connection To Pv Generator (Dc Side)

    5 - Installation nput connection to PV generator (DC side) Once preliminary checks have been carried out and no problems found with the photovoltaic system, and the channel configuration has been se- lected (parallel or independent) you may connect the inputs to the inverter. When the photovoltaic panels are exposed to sunlight they provide continuous DC voltage to the inverter.
  • Page 49 5 - Installation According to the system configuration, check the correct setting of the channels to indepen- dent or in parallel mode. An incorrect setting of the input channels can lead to loss of energy production. Polarity inversion can cause serious damage. Check polarity before connecting each string! Connect all the strings required by the system, always checking the seal of the connectors.

    8 - Maintenance eplacing the input fuses (version -FS) Using fuses with inappropriate specifications may irreparably damage the unit. Any conse- quential damage to the inverter is not covered by the warranty. In case of damage of one or more input fuses, the inverter (not being able to monitor the sta- tus of fuses) will continue to export energy to the grid without signaling any alarm.

  • Page 102: Verification Of Ground Leakage

    8 - Maintenance erification of ground leakage In the presence of anomalies or report of ground fault (where provided), there may be a ground leakage from the PV generator (DC side). To check this, measure the voltage between the positive pole and ground and between the negative pole (of the PV generator) and ground using a voltmeter whose input accepts a voltage sufficient for the dimensions of the photovoltaic generator.

    8 - Maintenance ehaviour of a system with leakage If the voltage measured between one of the two poles and ground does not tend to 0V and stabilizes on a value, there is a ground leakage from the PV generator. Example: When the measurement is made between positive pole and ground, a voltage of 200V is measured.

  • Page 104: Measuring The Insulation Resistance Of Photovoltaic Generator

    8 - Maintenance easuring the insulation resistance of photovoltaic generator To measure the insulation resistance of the PV generator compared to ground , the two poles of the PV generator must be short-circuited (using a suitably sized switch). Once the short-circuit has been made, measure the insulation resistance (Riso) using a megohmmeter positioned between the two shorted poles and ground (of the inverter).
