PVCHECKS KIT HT Instruments Curve Tracer

HT Instruments PV Checks KIT - Installation Safety Tester

The multifunction instrument PVCHECK allows prompt and safe electrical checks required for a PV system (section DC) as well as controls on working of modules / strings in accordance with IEC/EN62446 guidelines. PVCHECK verifies the continuity of the protective conductors (and the associated connections) and executes insulation resistance measurement of the active conductors on a module, a string or a photovoltaic field in accordance with the requirements of IEC/EN62446, without the need of short-circuiting the positive and negative terminals. PVCHECK allows verification of a PV string's working in accordance with the requirements of IEC/EN62446 by measuring the open circuit voltage and short-circuit current under operating conditions and reporting the results to STC (by means of radiation measurement). It provides an immediate outcome for both absolute measurements and for measurements compared with the previously tested PV strings. PVCHECK also allows carrying out performance analysis of PV array (DC) under operating conditions (connected to the inverter) providing an indication of the power generated and the efficiency of the field as specified by IEC/EN62446.

Features:

• PVCheckS + Hard Case + HT304N
• 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

Check the insulation of the entire PV array with a single test.

No longer need to wait for the night or cover the photovoltaic modules to verify insulation of the modules HT PVCHECK is able to perform the verification of the insulation system with voltage without the need to use an external switch to put in short-circuit the positive and negative terminals.

Available values for insulation test:

• 250V
• 500V
• 1000V

Performance Analysis of the photovoltaic field

HT CHECK PV also allows the execution of performance analysis of the PV array (DC) of the operating conditions (then connected to the inverter) with the use of optional accessories SOLAR-02, HT304N and PT300N providing an indication of the generated power and performance the same field as indicated by IEC/EN62446.

Reference Cell HT304N

The HT PV CHECK as optional accessory has a reference cell that is located next to the photovoltaic module using the appropriate bracket, will measure the solar radiation. This is necessary to calculate the performance of the plant in operating conditions.
