How to test a PV installation using the new HT PVcheck s

http://www.ht-instruments.com Safety test of PV installation Measurement of open circuit voltage up to 1000V DC Measurement of short circuit current up to 15A DC 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 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
