TIS Solar PV Multifunction Performance Tester Kit PV-ISOTEST

TIS Solar PV Multifunction Performance Tester PV-ISOTEST

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 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.

This versatile tester is designed to evaluate insulation resistance at multiple voltage levels (250V, 500V, 1000V, and 1500V) to ensure the integrity of electrical insulation. It boasts a Ground Fault Locator (GFL) function that precisely identifies ground fault positions within the string, streamlining troubleshooting.

Additionally, the PV-ISOTEST offers essential measurements like the Polarisation Index (P.I) and Dielectric Absorption Ratio (D.A.R) to assess insulation health. Its measurement capabilities span both DC and AC circuits, meeting CAT III 1500V DC and CAT III 1000V AC safety standards.

With features such as AC TRMS voltage measurements (3 ÷ 1000V) and DC voltage measurements (3 ÷ 1500V), it provides accurate voltage assessment for PV systems. The tester also verifies the continuity of protective conductors with 200mA, enhancing electrical safety.

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.
