PVCHECKs – Device for electrical safety and PV performance

PVCHECKs – Device for electrical safety and PV performance

Description

Multifunction device for commissioning tests on PV systems.

Automatic test in a sequence of:

  • Measurement of insulation up to 1000VDC
  • Open-circuit voltage and short-circuit current Voc/Isc up to 1000V/15A
  • Continuity of protective conductor with 200mA

The multifunction device PVCHECKs allows quickly and safely carrying out the electric safety tests provided for a PV system (section in DC) and the functional test of modules/strings the system consists of according to the requirements of Standard IEC/EN62446. When testing safety, PVCHECKs is a real innovation, since it is capable of measuring insulation of a module, string or of a whole photovoltaic field (IEC/EN62446) with no need to use an external switch to short-circuit the positive and negative terminals. PVCHECKs also allows checking the functionality of the connections and of the strings in a photovoltaic field, according to the provisions of standard IEC/EN62446 by measuring the open circuit voltage and the short-circuit current at operating conditions (OPC) and referred to STC (via the optional measurement of irradiation, also with the use of optional accessories SOLAR02 and HT304N), providing an immediate result as regards the measurement just carried out, both in absolute terms and by comparison with the previously tested strings. Finally, PVCHECKs also allows analyzing the performance of the photovoltaic field (DC) under operating conditions (therefore connected to the inverter) with the use of optional accessories SOLAR02 and HT304N, providing an indication of the generated power and of the performance of the field itself, as required by IEC/EN62446.
