HT-INSTRUMENTS PVCHECKs Meter for safety, functionality and performance on PV plants The new commissioning tester PVCHECKs enhances the maximum current to be measured up to 15A. This speeds up the test procedure, and allows to test even the last generation PV modules. The multifunction instrument PVCHECKs performs prompt and safe electrical checks required for a PV system (DC section) and controls of the functionality of modules / strings in accordance with IEC/EN62446 guideline PVCHECKs: safety checks PVCHECKs verifies the continuity of the protective conductors (and associated connections) and measures the insulation resistance of the active conductors on a module, a string, or a photovoltaic field in accordance to IEC/EN62446 guideline, without the need of any external switch to short-circuit the positive and negative terminals. PVCHECKs: safety checks PVCHECKs verifies the continuity of the protective conductors (and associated connections) and measures the insulation resistance of the active conductors on a module, a string, or a photovoltaic field in accordance to IEC/EN62446 guideline, without the need of any external switch to short-circuit the positive and negative terminals. PVCHECKs: functionality checks PVCHECKs verifies the functionality of a PV string in accordance to the IEC/EN62446 guideline by measuring the open circuit voltage and the short-circuit current at operating conditions up to 15A and extrapolating the results to the STC (by measuring the solar radiation). Finally, it displays the measurements and a comparison to the PV strings previously tested. PVCHECKs: performance checks PVCHECKs analyses the performance of a PV array (DC) under the operating conditions (connected to the inverter) displaying the generated power and the efficiency of the PV plant in accordance to the IEC/EN62446 Functions: Safety test of PV installation Continuity test on protective conductors with 200mA Insulation test with test voltage of 250, 500, 1000VDC DC voltage DC current DC Power Solar irradiation [W/m2] with reference cell Environmental and module temperature by means of PT1000 probe SOLAR-02: remote unit for irradiance and temperature measurements (RF connection). Recording of PV plant parameters (DC side) with programmable IP (5s – 60min) Use of PDC compensation ratios according to environmental and module temperature Use of relationship to maximize the DC efficiency Outcome OK/NO Check of PV string's working Measurement of open circuit voltage up to 1000V DC Measurement of short circuit current up to 15A DC Measurement of temperature, automatic or by means of PT1000 probe Measurement of solar radiation [W/m2] with reference cell Mechanical inclinometer for the detection of solar radiation incidence angle Comparison with standard conditions (STC 1000 W/m2, 25°C) Outcome of testing: OK / NO Database to manage up to 30 types of photovoltaic modules Internal memory for data saving Optical/USB port for PC connection Help on line on display
