Testeur d'installation PV HT Instruments PV-CHECKs VDE 0126 (1009501)

The PV-CHECKs stands apart as a dedicated photovoltaic installation tester, combining insulation resistance measurement, open-circuit voltage, short-circuit current, and continuity checks in a single handheld instrument. It addresses the specific verification needs of solar PV systems under VDE 0126, streamlining commissioning and periodic inspection workflows.

Highlights

• Measures insulation resistance at 250 V, 500 V, and 1000 V DC up to 999 MΩ
• Records open-circuit voltage (Voc) up to 1000 V DC and short-circuit current (Isc) up to 15 A
• Continuity of protective conductors with 200 mA test current
• Calculates PV performance parameters: Pmax, Vmax, Imax, fill factor, and efficiency
• Internal memory for up to 999 measurements with USB interface for data transfer
• Backlit LCD for clear readings in various lighting conditions

In daily use

The PV-CHECKs simplifies field testing by guiding the operator through required measurements and storing results for later analysis. Its rechargeable Li-ION battery supports over 500 measurements per charge, reducing downtime on large installations. Optional external sensors allow environmental irradiance and temperature data to be factored into performance calculations.
