PVA-1500V4 PV Analyzer Kit

The PVA-1500V4 has been discontinued. Please see the PVA-1500T for the next closest model.

I-V Curves and PV Performance Verification

The PVA-1500V4 PV Analyzer Kit is a 1500 volt I-V curve tracer with built-in PV performance modeling and advanced wireless irradiance, temperature and tilt sensing. It provides unprecedented accuracy and delivers deep insight into the performance of your arrays.

For each string, the PV Analyzer measures the I-V (current vs. voltage) and P-V (power vs. voltage) curves with a single button click. The measured results are compared to the expected performance, taking into account the irradiance and module cell temperature at the time of the I-V measurement. The user interface is via your Windows tablet or laptop (not included), which connects via WiFi to the PVA, and presents a large clear display of your results in the field.

Irradiance, module temperature, and tilt are measured with the SolSensor. The I-V Unit communicates wirelessly to the Solsensor, enhancing safety and allowing freedom of movement during testing. Automated data analysis and reporting save you time.

Measure strings up to 30 Amps. This can be useful for measuring multiple strings in parallel, for example when harnessing before the combiner box is employed. Please note, however, the maximum current for strings of high efficiency modules with ≥ 19% efficiency is 10 Amps. For more information on high efficiency modules, see the Solmetric app note I-V Curve Tracing of High Efficiency PV Modules.

Save Time, Reduce Risk, Maximize ROI

I-V curve testing is the preferred method for commissioning, O&M, and troubleshooting of PV arrays because it provides the most complete performance measurement possible. Populations of curves can be analyzed quickly for outliers and data can be archived as a baseline for future reference if performance questions arise. Maximize your ROI--Return On Irradiance!


Included with the PVA-1500V4

SolSensor-300 Wireless PV Reference Sensor (included): Irradiance, module temperature, and tilt readings are captured at the instant the I-V curve is measured. Improves effectiveness of expected performance models. The SolSensor has a range of more than 300 ft and includes a module rail clamp and precision mounting system for POA alignment.

PVA Test Leads (included): 1500V rated alligator-clips ("dolphin" clips) enable connecting directly to combiner box bus-bars. more...

I-V Data Analysis Tool (included): Excel macro for analysis of populations of curves and data plus report generation. more...


Transit Case Option:
This rugged waterproof, dust-proof, and crush-proof Pelican case has durable custom foam cutouts for the I-V unit, SolSensor, and accessories as well as a pocket for a laptop/tablet (up to 14" x 10"). Includes wheels and retractable handle for easy transportation. Also holds the field recharging kit, including the folding solar panel. more... PVA

Field Charging Kit Option:
This field charging kit enables you to charge your I-V unit or SolSensor from solar or from an external battery pack for those extra-long days in the field.

Returns: Orders may be returned within 30 days of purchase with a 10% restocking fee. Returns are not accepted for orders more than 30 days old.

Computer Requirements

The PV Analyzer requires a Windows laptop or tablet that is not included with a PVA purchase. Minimum requirements and recommendations are given below.

  • OS: Windows 7, 8, 10, or 11
  • Processor speed: 2 GHz or more
  • RAM: 4 GB or more
  • Hard drive: 100 MB free space or more
  • Screen resolution: at least 1024 x 600
  • Bright outdoor readable display
  • USB port
  • An extended life battery, swappable battery, or external backup battery is convenient for full days of testing (a 4MW system can take 8 hours to measure every string.
  • For extreme, hot, or dusty environments we strongly recommend the Panasonic Toughbook or similar.
Systems that do not meet these requirements may not operate correctly.
