The UNI-T UT503PV is a dedicated insulation resistance tester engineered specifically for photovoltaic systems. It measures insulation resistance on live PV strings at up to DC 1000 V, meaning you can verify an entire array without shutting it down or short-circuiting panels and since the measurement doesn't rely on sunlight, testing is fully functional after dark. Compliant with IEC 62446, it offers four selectable test voltages (125 V, 250 V, 500 V, and 1000 V) and a measurement range reaching up to 4000 M with an accuracy of ±( 1.5 %+5).
Safety features include automatic discharge after each test, a high-voltage alarm, and a CAT II 1000 V / CAT III 600 V rating. The IP54-sealed body holds up to outdoor rooftop and ground-mount environments. Stepped-voltage testing and a comparison function simplify pass/fail diagnostics, while onboard storage holds up to 1000 result sets transferable via USB or Bluetooth app ideal for commissioning reports and maintenance records. Weighing approximately 1.1 lbs and compact enough for field work, the UT503PV is also well-suited for EV-charging and battery energy storage DC wiring verification.
