PV Measurement Device for commissioning, troubleshooting & maintenance of PV systems up to 1500V DC

The PV-ISOTEST determines the insulation resistance of a single module, a string, or even an entire PV field with a test voltage of up to 1500V DC according to EN62446 (VDE0126-23). Conventional insulation testers require a suitable adapter due to the presence of the string voltage to short-circuit the positive and negative connections of the PV string to be tested. With PV-ISOTEST, the use of an external device is not necessary. The PV-ISOTEST performs the insulation measurements in full autonomy and self-sufficiency. In addition, the PV-ISOTEST, with the help of the new GFL function (Ground Fault Locator), also shows you the exact position of an insulation fault in a string of the PV system.

• Insulation measurement up to 1,500V DC even on live systems
• Localization of the insulation fault on a PV string using the new GFL function
• Low resistance measurement (protective conductor) with a test current > 200mA
• Measurement of Polarization Index (PI) and Dielectric Absorption Ratio (DAR)
• Measurement of AC voltage components in the PV string

The PV-ISOTEST is a true innovation in our exclusive range of PV measuring devices!
