Power Measurement & Curve Tracer for PV modules & Strings

Supplier: Zedflo Australia

The Gossen Metrawatt Profitest PV tester allows for measurement of characteristic I-U curves and individual solar panel photovoltaic modules and strings.

Price Guide: POA

The Profitest PV is a high precision and fast measurement (20ms) PV testing system.

With the patented process, the instrument can ascertain peak power, internal series resistance and internal parallel resistance directly on-site. This is achieved with only one measurement and without the need to enter the module data.

The unit features:

  • Internal data memory for up to several thousand measurements
  • Measures short circuit current ISC, open circuit voltage UOC, instantaneous peak power of a solar cell Pmax, internal resistance RS, and internal parallel resistance RP
  • Automatic conversion of momentary measured values to STC
  • Patented calculation process for evaluating PV generators - without the need for knowledge of  manufacturers specifications
  • Seperate measurement of temperatures at the irradiation sensor and the back of the module under test for increased measuring accuracy
  • High level of intrinsic safety due to load disconnector
  • Software for graphic visualisation, evaluation & report generation with integrated database

Testing and troubleshooting of PV systems, as well as documenting of system quality is executed quickly and economically during start-up and subsequent testing without a long learning curve. The simple yet decisive test assures safety for the customer and eliminates consequential costs for the manufacturer / installer.

The unit is manufactured in accordance with IEC 61010-1 and complies with IEC 62446 for use of the test instrument
