Description
Professional I-V Curve Analysis Tool for Solar PV Performance Testing
TIS I-V400W Solar I-V Curve Tester
The TIS I V400W Solar I V Curve Tester is a powerful diagnostic instrument designed for detailed performance analysis of photovoltaic modules and strings. It enables accurate field measurement of I-V curves for PV installations up to 1000V and 15A, supporting commissioning, maintenance, and fault diagnosis.
This advanced tester captures up to 128 points per I-V curve in standard or capacitive mode, measuring key parameters including Voc, Isc, Pmax, Vmpp, Impp, and fill factor. Measured values are automatically compared with manufacturer-rated data using an internal, user-updatable PV module database, providing an immediate OK/NO assessment of system efficiency.
The I-V400W supports irradiance and temperature measurement either directly or remotely using the optional SOLAR02 unit, synchronised with the tester for precise, real-world performance evaluation. Clear on-screen results and PC connectivity make it an essential tool for professional solar engineers.
