CODMETEL: HV00PVCS-2001Inquire now
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 PV-215 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, PV-215 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. PV-215 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, PV-215 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. Instrument available on the Chinese market through HT China office only"
