Professional High-Voltage Solar Clamp Meter

The UNI-T UT219PV is an advanced, heavy-duty digital clamp meter purpose-built to meet the stringent demands of modern utility-scale and commercial photovoltaic installations. As solar arrays adopt higher string voltages to minimise power transmission losses, field technicians require test instruments capable of safely handling extreme potentials. The UT219PV delivers high-tier measurement capabilities, accommodating up to 2500 V DC and 1500 V AC, making it the ideal diagnostic instrument for solar farm commissioning, inverter maintenance, energy storage systems (BESS), uninterruptible power supplies (UPS), and high-output industrial motors.

Designed for Dense Enclosures and Field Usability

Navigating tightly packed cable trays, array combiner boxes, and compact inverter switchgear is effortless thanks to the UT219PV's 35 mm ultra-thin jaw profile. Technicians can isolate individual conductors without pinching adjacent wiring. The dual 9999-count LCD screen provides simultaneous voltage and current (V+A) readouts, cutting test times in half. For environments with variable frequency drives (VFDs) and electrical switching noise, the integrated Low Pass Filter (LPF) suppresses high-frequency interference to yield steady, reliable True RMS measurements.

Safety, Reliability, and CE Compliance

Working around high-voltage DC circuits demands zero compromise on user protection. The UNI-T UT219PV complies fully with harmonised European safety norms, holding complete CE conformity alongside CAT III 1500 V and CAT IV 600 V overvoltage safety ratings. An acoustic and visual polarity alert triggers instantly if probes are reverse-connected on PV strings below -10 V DC, guarding equipment and personnel against connection mistakes. Furthermore, its IP65-rated enclosure shields internal electronics from torrential rain, windblown dust, and jobsite debris, providing steadfast reliability in demanding industrial settings.

Data Logging and Workflow Automation

Equipped with integrated Bluetooth 5.0, the UT219PV connects directly to your smartphone or tablet. Technicians can view measurements in real time from a safe distance outside the arc-flash boundary, record long-term trend data, and generate professional PDF reports on-site. When expanded testing capability is required, the unit is compatible with the optional UT-CS09D flexible clamp sensor, allowing AC current measurements up to 3000 A.

Technical Specifications

Frequently Asked Questions

Why is a 2500 V DC rating important for solar installations?

Modern commercial and utility-scale photovoltaic systems operate string voltages of 1500 V DC or higher under open-circuit conditions (Voc), particularly in cold weather. Standard 600 V or 1000 V multimeters cannot safely handle these potentials. The UT219PV's 2500 V DC rating ensures adequate safety headroom and prevents instrument overload.

How does the solar polarity alert function work?

When measuring DC circuits, if the meter detects a reverse voltage lower than -10 V DC, it immediately warns the user via a flashing red LED indicator, an acoustic buzzer, and a POLARITY icon on the LCD display, helping avoid miswiring before energising systems.

Does the UT219PV meet European safety and quality standards?

Yes. The UNI-T UT219PV complies with all applicable EU harmonisation directives and bears the CE mark. It meets international electrical safety standards under CAT III 1500 V and CAT IV 600 V overvoltage classifications.

What are the benefits of the built-in Low Pass Filter (LPF)?

Inverter outputs and high-power motor drives generate pulse-width modulated (PWM) electrical noise that can distort standard multimeter readings. The LPF attenuates high-frequency noise above fundamental power frequencies, delivering true, stable voltage and current measurements.

Can I export measurement data for client documentation?

Yes. With integrated Bluetooth 5.0 and the dedicated mobile app, you can stream real-time readings, record logs over extended periods, and export reports directly from the field via email or messaging apps.
