HT Instruments PVCheck Installation Safety Tester

HT Instruments PVCHECK Installation Safety Tester Multifunction instrument to check safety, parameters and performance of a PV plant. 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. IEC EN62446? Just in one test. Voc – Isc Insulation Resistance Continuity of protective conductors 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
