PVPM1000X Innovative peak power and I-V-curve measurement device (curve tracer) for photovoltaic modules und strings up to 1000V and 20Adc

The devices series PVPM provide the measurement of the I-V-curve of photovoltaic modules as well as strings. By a patented procedure the device can measure and calculate the peak power Ppk, the Rs and Rp from a single I-V-curve directly at the place of assembly of the PV system. Calculation results and the diagram can be displayed on the internal graphical LC display.

The input of detailed module parameters is not required in common.

The PVPM1000X is a mobile measuring device with integrated battery supply and external battery charger in a durable and watertight plastic housing. The device has its own industrial miniature PC and a high-contrast LCD TFT display and thus its function is independent of other devices. However if desired a PC can be attached for data transfer and further analysis of the measured values over a standard USB interface.

The PVPM is operated comfortably over the touch function of the display and an on-screen menu. The functions are defined self-describing and the user is always led by the program. So no long training activities for the operating staff are necessary.

Build in a stable and waterproof (IP67) plastic case with carrying handle, automatic pressure valve and tough front panel.

Measuring Unit:

  • Miniature industrial PC 32Bit, real time clock, no mechanical moving parts
  • Sampling rate max. 100kHz
  • Resolution 0.01V - 0.25V, 0.005A – 0.01A (depending on sel. range)
  • Accuracy of the a/d converter 0.08% of FSR±1 LSB
  • Accuracy Peak power measurement: ±5%
  • Reproducement: ±2-3%
  • Duration of single measurement: 20ms up to 2 seconds, avoiding the influence of capacitive properties of the module under test
  • Non volatile data storage for several thousand measurements
  • Irradiance reference sensor (Phox) with integrated Pt100 or Pt1000 temperature sensor measures irradiance and cell temperature
  • Other commercially available sensors as e.g. ISET-Sensor® can be connected using a reliable cable connection
  • 4-wire-cabling between PVPM and generator under test avoids mis-measurement of voltage
  • Additional measurement of the back surface temperature of the module under test (second input for Pt100 RTD available)
  • Continuous long-term measurements of I-V-curves in selectable time intervals

The device may only be attached to a limited source of direct current (photovoltaic generator) with at most 20A
