    Choice of differential protection downstream of the inverter All FIMER string inverters marketed in Europe are equipped with a de- vice for protection against ground faults in accordance with the safety standard set in Germany by Standard VDE V 0126-1-1:2006-02 (please refer to section 4.7 of the Standard).
  • Page 42 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, FIMER 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 99: Replacing The Input Fuses (Version -Fs)

    8 - Maintenance Replacing 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 Verification 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.

  • Page 103: Behaviour Of A System With Leakage

    8 - Maintenance Behaviour 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 Measuring 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).
