Solar PV Tester PVChecks for PV System

The PVCHECKs is a multifunctional testing instrument designed to perform rapid, safe, and fully compliant commissioning tests on photovoltaic (PV) systems in accordance with IEC/EN62446 standards. Tailored for DC-side verification, it enables users to conduct all required electrical safety and performance checks on modules, strings, and entire PV fields—without the need for external shorting switches.

✅ Key Features and Measurements:

• Insulation Resistance Measurement up to 1000VDC on modules, strings, or entire PV arrays—compliant with IEC/EN62446

• Voc (Open-Circuit Voltage) and Isc (Short-Circuit Current) measurement up to 1000V / 15A

• Continuity Test of Protective Conductors using 200mA test current

• Automated Test Sequence – Perform all core PV safety checks with a single command

• No external jumper required for insulation testing, ensuring greater safety and speed

• Real-time comparison of string performance, both at Operating Conditions (OPC) and Standard Test Conditions (STC)

• Optional performance analysis under live inverter connection using accessories like SOLAR-02 and HT304K
