Multi-Channel I-V Measurement Systems for PV Modules

The Atonometrics 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

The Atonometrics PV Module I-V System can also be mounted in a in a ruggedized, portable carrying case.  This configuration of the I-V system provides all the benefits of our standard rack-mount I-V system, but allows users to make PV module characterization measurements in the field.

The Atonometrics I-V Measurement System for PV Modules is a versatile tool designed to meet your specific PV testing goals.  Contact us for more information on this or our other products.
