UNI-T UT503PV Solar Photovoltaic (PV) Insulation Tester – 1000V

The UNI-T UT503PV is a specialized insulation resistance tester designed specifically for the solar energy sector. It uniquely allows insulation testing on live photovoltaic (PV) strings at energized voltages up to 1000V DC without requiring a system shutdown. Measuring up to 4000MΩ, it features Bluetooth app connectivity and automatic voltage recognition for seamless solar plant commissioning.

Secure your solar investments with the UNI-T UT503PV Solar Photovoltaic Insulation Tester. As Pakistan rapidly shifts toward renewable energy, solar installers face a major challenge: testing the insulation of a massive solar array during the daytime when the panels are actively generating high-voltage DC current. Standard insulation testers will blow their internal fuses if connected to a live solar string. The UT503PV changes the game entirely.

This instrument is engineered to perform highly accurate insulation measurements even when the Device Under Test (DUT) is energized up to 1000V DC. This means solar technicians can troubleshoot active arrays and string inverters without shutting down the entire plant or waiting for nightfall. Delivering test voltages up to 1000V and measuring up to 4000MΩ, it guarantees the safety and efficiency of your solar installations. Results can be synced directly to your smartphone via the UNI-T Bluetooth App for instant digital reporting.
