Description
Advanced Insulation & Safety Tester for Professional Solar PV Systems
TIS PV-ISOTEST Solar PV Multifunction Tester
The TIS PV ISOTEST Solar PV Multifunction Tester is an innovative solution for insulation and safety testing in modern photovoltaic installations. Designed to meet IEC/EN 62446 requirements, it enables reliable insulation resistance testing of single modules, strings, or entire PV fields up to 1500V DC.
Unlike traditional insulation testers, PV-ISOTEST eliminates the need for external DC-rated switch boxes. It performs all insulation measurements autonomously, improving safety and efficiency during commissioning and maintenance. This makes it ideal for installers working on high-voltage PV systems.
Equipped with an advanced Ground Fault Locator (GFL), the PV-ISOTEST can accurately identify the position of insulation faults within a PV string, helping technicians quickly locate issues caused by moisture ingress or insulation degradation.
