Multi-Channel I-V Measurement System measures the current-voltage relationships (I-V curves) of photovoltaic (PV) modules.
The system can both source and sink current, providing multi-quadrant measurement capability. This enables measurement of PV module I-V curves under either illuminated (light I-V) or non-illuminated (dark I-V) conditions.
The master chassis provides for measurement of a single PV Module, and the optional expansion chassis allows for the simultaneous testing of up to six PV modules.
Features include:
Configurations available for a wide range of PV module currents and voltages.
Input channels for module temperature measurements (Pt-100 RTD or type K Thermocouple)
Tracking modes, which allow the user to actively track Pmax, Voc, Isc, or any fixed current or voltage
System software to extract typical device parameters inclulding Isc, Voc, Impp, Vmpp, Pmax, and others
Ability to operate in either a standalone mode or as part of an automated process control system
Separate input for a PV reference cell for irradiance measurement
