■ 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), 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.
