The TIS IV-PRO is the most advanced multifunction PV tester ever developed, being the combination of an I-V curve tracer meeting IEC 60891, and a commissioning tester meeting the IEC 62446-1 standards.
IV PRO is a one-stop test solution to take category 1 and category 2 commissioning tests, to measure the performance and functionality, and to troubleshoot single face and bifacial modules in PV systems.
IV PRO: I-V curve tracing (performance/acceptance test)
IV PRO verifies the performance of PV strings in accordance with IEC 60891 by tracing the I-V curve up to 1,500V and 40A. Through the solar radiation and PV module temperature measurements (main unit wirelessly connected and/or synchronized to the remote unit SOLAR03), IV PRO extrapolates curves to the STC (Standard Test Conditions: 1000W/m2, 25°C, AM 1.5) and compares them to the nominal values provided by the module manufacturer. The wide internal database already stores more than 40,000 modules, more modules can be added.
Finally, IV PRO provides a positive or negative outcome (OK/NO).
IV PRO: Commissioning tests
IV PRO performs all tests required by the IEC 62446-1 to commission a photovoltaic installation in automatic sequence. Therefore, by a single GO-key push measures and tests:
- Continuity of protective earthing and/or equipotential bonding conductors, where fitted;
- Polarity test;
- String open-circuit voltage test up to 1500V;
- String short-circuit current test up to 40A;
- Insulation resistance of the DC circuits by generating up to 1500V even on live circuits.
