Solar PV Multifunction Performance Tester The PV-ISOTEST represents a real innovation in the panorama of PV verification and testing instrumentation. PV-ISOTEST measures the insulation resistance of a single module, a string or even an entire photovoltaic field up to 1500V DC according to the IEC-EN62446 standard. Traditional insulation meters would require a DC-rated switch box to short-circuit the positive and negative terminals of the module/ string/ PV field under test. With the PV-ISOTEST the use of any external device is not required, PV-ISOTEST carries out the measurements in full autonomy and self-sufficiency. In addition, through the new GFL (Ground fault locator) function, PV-ISOTEST indicates the position of any poor insulation on a string of the PV system, due for example to water or humidity leakage.
