The multifunction instrument PVCHECKs-ONE allows fast and safe execution of all electrical safety tests required for the DC side of a PV system, as well as functional verification of open-circuit voltage (Voc) and short-circuit current (Isc) of modules and strings, in compliance with IEC/EN 62446.

In the field of electrical safety testing, PVCHECKs-ONE represents a true innovation: thanks to the DUAL function, insulation resistance measurements can be performed on a single module, a string, or an entire PV array without the need for an external switch to short-circuit the positive and negative terminals.

The instrument also enables functional verification of PV connections and strings according to IEC/EN 62446 by measuring Voc and Isc under Operating Conditions (OPC) and referring the values to STC through irradiance measurement, including the use of the optional accessories SOLAR03 and HT305.

At the end of each test, an immediate result is provided, both in absolute terms and by comparison with previously tested strings, supporting a rapid assessment of the system status.
