PROVA 1011 PV (Solar) System Analyzer


The Prova 1011 is the perfect instrument for determining the ideal solar panel location and then can measure panel performance (I-V curves), maximum power point, isolation—all vital in making an efficient solar panel installation.

 Use the Prova 1011 for installations up to 12 kilowatts and also measure panel temperature. It can test individual panel performance for MPP (perfect for choosing roof location) and display I-V curves, VOC and ISC, VPM and IPM at max. power.

The Prova 1011 will measure the overall system efficiency for converting the DC power to AC power and can communicate to your computer via wireless bluetooth or through it’s optically isolate USB connector.

Prova 1011 Features:

■       I-V curve test for PV system.

■       Max. PV system power (Pmax) search by Auto-scan: 1000V, 12A (12000W capability).

■       The analyzer and the Remote Solar Detector is connected by Bluetooth wireless communication (Bluetooth 2.1 + EDR Class 1).

■       The Remote Solar Detector is moisture-proof.

■       Intelligent test logic with no personnel attendance required in the field.  PV system analyzer waits and tests the system until appropriate sunlight irradiance is detected.

■       Max. voltage (Vpm) at Pmax; Max. current (Ipm) at Pmax.

■       Voltage at open circuit (Voc); Current at short circuit (Isc).

■       Efficiency (%) calculation of PV system.

■       Temperature measurement of solar panels.

■       Irradiance measurement of sun light.

■       Series resistance (Rs) calculation of solar panels.

■       I-V curve with cursor to display each data point.

■       With data logging/open function, the I-V curves of PV system can be analyzed/recorded for a period of time (e.g. 60 min.).

■       Conversion of I-V curve under OPC to data under standard test condition (STC) based upon IEC standard

■       Provide Operating Condition (OPC) and Standard Test Condition (STC) test reports for verification of solar panel performance (OK, or NO OK).

■       Users can set up the parameters of solar panels; users can set up the series numbers of solar panels.  Parameters of many solar panels can be measured in one measurement.

■       Irradiances & temperatures of solar panels can be continuously measured, monitored and  recorded.

■       Built-in calendar clock.

■       Rechargeable lithium battery, low battery warning; AC power adaptor.

■       Optical USB cable for PC.

■       With OPTIONAL power clamps (SOLAR 15 DC Current Probe and SOLAR 21 AC Power Clamp), the PROVA 1011 can continuously measure/monitor/record the DC power output of PV system and the AC power output of inverter (1 phase or balanced 3 phases); calculate the efficiency of DC to AC power conversion and the efficiency of the max. output power
